i pitted at the end of lap 2 incase the weather opened up and it did from lap 3 to 5 had to stick to inters the rest of the race at lemans
 
I've had a lot of fun with the BoP/stock Gr4 events, so I started thinking about other categories to toss into the WTC 700 grind. After a bit of testing here are some ideas for GrB, Gr3, and Gr2 in the same spirit of winnable but not boringly easy.
1. GrB rally cars, racing hard tires, max down force, stock turbo and the one thing to buy, custom RACING transmission for taller gearing. All I did for tuning was lower the ride height and set 6th gear at 305 kph. The stock GrB's destroy this race on all levels so I came up with a hybrid BoP system based on PP with different values for MT and AT.
a. Easy mode; 600 PP for manual and 603 PP for automatic. Needs power restrictor to get down to 600.
b. Normal mode; 610 PP for MT and 615 PP for AT.
c. Hard mode; 625 PP for MT and 635 PP for AT.
2. Gr3, racing hard tires, all stock with aero at 400 and 600. Experiment with the aero, I just used stock for testing. I found more PP variation with the Group 3's so their detuning is simply power based.
a. Easy mode; Computer at 70, restrictor at 75. I didn't do a lot of testing on EASY, might need adjusting.
b. Normal mode; Computer @ 70, restrictor @ 85.
c. Hard mode; Computer @ 70 for MT, @ 75 for AT, no restrictor.
3. Group 2 only '19 and newer for now.
a. Hard mode; Just get under 700 by any means necessary! Normal and easy mode are just too easy...

Pick a flavor and have fun!
 
Checked another 20 million car off the list, the Mercedes W 196 R '55. I took the 70 year old F1 for a spin around le Man box stock. First lap I'm dicing with the back markers, figuring out fuel and brakes. Brakes are great and looking like 7 laps on FM1. Second lap sitting in the draft hoping for a dry race no stop, not to be. A fast moving storm shows up near the end of lap 2, doesn't look like a monsoon but I gambled on inters and no fuel. Start of lap three the rain hasn't begun but it's coming, I glance down to check the lap 2 fast lap time and see the Viper post a 4:15! I forgot to change off Hard mode, oh well let's see what happens. I got lucky with the weather and was able to nurse the inters 5 laps for the win. Great little car, but next time the 604.92 PP will be on Easy mode.

I was searching my garage for more low horsepower candidates, which means searching by weight, and found one I had previously overlooked. The seventh lightest car in my garage weighing in at 1213 lbs, the Red Bull junior. I think the high downforce made me pass over it before but decided to give it a try. What an amazing and versatile little car! It has awesome brakes, ridiculous fuel and tire economy and handles like it's on rails. The versatile part is that anywhere close to 700pp it will destroy any WTC 700 event on any difficulty and at full power, a whopping 246 Hp, can easily win all the WTC 800's up to normal. But I was looking for a low horsepower contender and found one.
Le mans; Standard no stop on inters strategy, easy win @ 119hp, as low as it can go and with worn oil. FM1 could go 9 laps.
Spa; First try at a low Hp run at Spa, no stop FM1, mostly dry race on RH, winner @ 168 Hp.
Sardegna; One try @ 199Hp no stop win on RM.
The low Hp stuff obviously done on easy, a great car for anyone looking to try out goofy low horsepower attempts.
 
I dusted off my original low horsepower mule, the Honda RA272 to run seven laps around la Sarthe. All of my previous low horsepower attempts have been based on the wet race, six lap, no stop on inters strategy. Could a car win a dry seven lapper at under 120 Hp?
YES! The little old Honda at 118 Hp does a seven lap no stop on racing mediums for the win.

Of course I had to try the RA272 as low as it can go, in my case 111 Hp with worn oil. Mostly dry race, laps 3 and 4 were damp and slippy but stayed on slicks. Same strategy as before, no stop FM1 on RM tires for the seven lap win! The Honda is a unicorn here.

Anybody else having experiencies with RA272 one-make races ?

That‘s one of the things I am still planing, but I only have 5 of them in my garage yet…is it worth to get 20 of them…?

I have been giving my copies liveries of other Formula racers of the time period, Jim Clark's Lotus, etc..
What i would like to try sometime on a weekend is set up a room and only allow fellow RA272 drivers and have a good old nostalgic race...

Just did a run with the 1989 Le Mans winner, the Mercedes Sauber C9.
Here is some history of that day....

SILVER TURNS GOLD

Mercedes-Benz, now presenting its cars in a nostalgic silver, landed a resounding 1-2, and it was even more impressive than the similar result 37 long years before. The factory team had the fastest car in the place, monopolized the front row of the grid, and took a third car to the finish, in fifth place.

Hermann Hiereth and his engine team in Unterturkheim developed the M119-HL, a racing evolution of the twin-turbo, 5-litre V8 with which the company's Group C project leader, Gert Withalm, reinforced the works status of Peter Sauber's team. Rated at 720bhp in race trim, the new, DOHC engine was more powerful, responsive and fuel-efficient.
The Sauber C9 was given a number of aero enhancements, resulting from the team's constant research in the Stuttgart wind tunnel, and was now much faster in a straight line. After the high-speed tyre failure in
June 1988, Michelin had come up with new solutions and these were thoroughly tested on the Ladoux and Clermont test tracks and at speed on a Canadian airforce base at Lahr, Germany. The revamped team began its 1989 programme right in the ball-park, with a 1-2 at Suzuka and a 2-3 at Dijon.

Jochen Neerpasch, the newly appointed Mercedes racing manager, brought 86 people to France, and TM Dave Price presented three cars to the scrutineers, their weights within a kilo of each other. All were fitted with low-downforce noses and underbodies, developed through substantial testing effort.

Jean-Louis Schlesser had declined to race here the year before, instead working as a TV commentator, but now he showed his affinity with the circuit when all alone in his car, away from the crowds and the razzamatazz he disliked so much. His C9, the only one equipped with a special electronic chip for qualifying and big, ventilated brake discs,
secured pole position aftfer reaching 282mph (373kph) on the Ligne Drofite.
Mauro Baldi ined up second even though his C9 (right) achieved 249mph (400kph). Jochen Mass, who hated the hype of Le Mans as much as "Schless', did not get a run on soft tyres before his fifth gear broke, which looked ominous to Bruno Fluckiger, a Swiss former Brun Motorsport engineer who was race-engineering this car.

Mass started and went all the way to second place during the first two stints. Manuel Reuter took over, but soon ran over an exhaust pipe dropped by another car, and lost five minutes in two stops to restore the front bodywork. A very strong recovery took the car to fifth place before midnight, and then Mass and Stanley Dickens, making the most of the best Sauber fuel economy, were consistently the fastest drivers all through the night. and steadily closed down the front-runners. When, at 6:15am, the leading Jaguar was delayed, the race was between two Saubers.

Baldi, his regular WSPC partner Kenneth Acheson and Gianfranco Brancateli drove cautiously at first but came on strong during the evening. Despite a spin by Acheson at Mulsanne corner, and time lost after the timing transmitter was dislodged in the cockpit, this car now took over the lead under challenge from its stablemate, and with deteriorating brakes. The pole position Sauber was racing out of contention in sixth place: Schlesse, Jean-Pierre Jabouil and Alain Cudini were unable to get maximum RPM from its engine, and had been delayed after Cudini clanged the barrier in avoiding a spinning C2 car.

At 7:30am, Baldi ran out of brakes at the Dunlop chicane, and scuttled into the gravel. Before he could rejoin the track, the lead was lost to Dickens, his grateful team mate. Baldi stopped for new pads, but all hope of retrieving the situation disappeared early in the afternoon when Acheson found his gearbox jammed in fifth. When time was up, the gap had opened out to five laps. One of the crew of the winning car had even found the time to clean up the three-pointed star on its grimy nose.
The team completed the season with six more FIA victories, clinching the Teams championship and the Drivers title with Schlesser.

I ran the Le mans 30 minute with another winning car, from 1995 it was the last GT car that had won Le Mans outright, and on it's inaugural run!
Here is more history on this specific race...


A MYTH EXPLODED

Conventional wisdom had it that no manufacturer would win Le Mans at its first attempt. Only Ferrari had ever done it, in 1949. And McLaren's achievement went further. All seven racing versions of the 'F in existence started, and displayed remarkable durability and pace in atrocious conditions. F1s were among the fastest cars out there when the rain was at its worst. One was crashed out, another broke its transmission, but the others finished 1-3-4-5, and 13th The winning F1 GTR (pictured) was raced by JJ Lehto Yannick Dalmas and Masanori Sekiya.

When McLaren went into production in Woking in 1992 with its innovative three-seat, mid-engined, butterfly-doored sportscar, it had not, envisaged racing it. However, designer Gordon Murray had created the ultimate 'supercar, using high-specification structures and running gear developed in the racecar industry. It was stiff, it was light, it had great, balance, it had 200mph performance - and it had a flat bottom between the axle lines with a ground-effect rear diffuser. The F1 was an advanced-composites monocoque, mostly formed of carbonfibre weaves over aluminum-honeycomb core material, with a front bulkhead of magnesium alloy. The carbon/Kevlar body, styled by

Peter Stevens and developed in the MIRA wind tunnel and McLaren's own facility, enclosed a cabin in which a central driver's seat was located slightly ahead of a passenger seat on each side,

After Honda had turned him down, McLaren chairman Ron Dennis approached BMW to provide the engine. The manufacturer's accomplished engine chief, Paul Rosche, purpose-designed a compact, lightweight, quad-cam, 6.1-litre, 60deg V12 with variable valve timing, and BMW built, tested and delivered it in only 13 months. It was bolted to lateral chassis extensions and a wide alloy casting, linked to the transmission bellhousing by steel tubes. Controlled by a TAGtronic management system, its output was 625bhp at 7400rpm, driving through a transverse, six-speed McLaren/Getrag gearbox.

In 1994, Dennis was finally persuaded by F1 owners, notably pharmaceuticals entrepreneur Ray Bellm and banker Thomas Bscher, to engineer a GT1 racing version for the 1995 BPR series. Dennis formed McLaren Cars Motorsport and recruited former Spice Engineering managing director Jeff Hazell as the project manager. Murray took the 19th F1 monocoque out of the production line and used it as a prototype to test modifications he designed with Barry Lett, including a non-structural rollcage, an adjustable rear aerofoil, various cooling ducts, and upgraded double-wishbone suspension and braking systems. BMW Motorsport took a close interest and the air-restricted race version of the 'atmo' V12 was rated at 640bhp at 7500rpm, with the catalytic converters and silencers removed.

After four months of development. six cars were delivered to four racing customers: two to Bscher, two to Bellm and his new racing partner, Lindsay Owen-Jones (who needed another in April to replace a car destroyed at Jarama), and one each to Noël del Bello and Fabien Giroix. The best-driven of these McLarens immediately set the pace in the BPR championship, taking six wins from the first seven four-hour events that preceded Le Mans.

In early May, the prototype completed a 22-hour test at Magny- Cours, evaluating a Le Mans kit and a dry-sump oiling system for the gearbox after several failures. The specification included carbon brakes and, to cool them, NACA ducts in the nose and engine cover. There were modifications to the underbody, extra protection for the radiator inlets, and strengthened lower suspension arms.

The customer teams were dismayed when the unpainted 'O1R' prototype arrived at Le Mans, attended by several McLaren personnel including four mechanics). This looked very much like a works entry, McLaren was outraged!

The company's line was that this car had been leased to a Japanese-owned company called Kokusai Kaihatsu UK translation: 'International Development UK"). After a deal with Giroix had fallen through, Paul Lanzante, a personal friend of Dennis who was operating a Porsche in the BPR series but had no Le Mans entry, was running the car here. Lanzante Motorsport was also on Le Mans début, but the car was race-engineered by former Spice technical director Graham Humphrys. The engine of the 'non-works' GTR was over-revved on Thursday, probably because a bent selector rod in the gearbox had damaged the synchros. The crew had to devote Friday to changing the engine and 1 rebuilding the gearbox, and the car was shaken down at 2am on race morning on the adjacent airfield. Another last-minute alarm came with a fuel pump failure on the dummy grid: the car raced throughout with the reserve pump.

After a great opening shift by John Nielsen, the first McLaren driver genuinely to lead the race was his co-driver, Jochen Mass, in the cockpit of one of Bscher's cars (below) operated out of Bookham, Surrey, by David Price. Despite a malfunctioning windscreen wiper, Mass, Nielsen and Bscher himself led on-and-off for more than nine hours. Soon after 3am, however, Mass pitted ahead of schedule, unable to cope any longer with a slipping clutch. After a 70-minute delay, Nielsen drove onto the beach at the second chicane and, with no drive, the car stayed there.

The other DPR-tended F1 C left, caked in carbon brake dust) Was raced by Andy Wallace with father-and-son co-drivers Derek and Justin Bell. Wallace led for a while on Saturday afternoon during a remarkable triple stint, some of it spent excitingly on slick tyres on a mostly damp track surface. When he finally handed the car to Derek, Price's crew had to spend 12 minutes replacing a broken throttle cable. Derek did a terrific job to claw back both the lost laps and, when the West FM-sponsored sister car had its clutch problem, the yellow Harrods McLaren was right there to take over the lead.

The KK McLaren was now chasing hard. A thoroughly absorbing battle ensued, during which the 'non-works' F1 came close enough to take the lead several times during the fuel-stop sequences. On Sunday morning, more exceptional driving by Wallace established a clear advantage, but then the Harrods F1 had to stop for fresh brake pads. Lehto charged. But 53-year-old Bell showed why he had won this race five times, and matched his lap times - until his transmission started to play up. This caused a 360deg spin in the Virage Ford and later, when he made the car's penultimate fuel stop, a five-minute delay while he found a gear (sixth) to get moving again.

The KK car took over at the front, and for good. Its sole problem was that spray and grit from the track surface were contaminating its external gearshift mechanism, but the crew immersed it in a bath of ND40 lubricant at every pitstop, and it held

In his final shift, Wallace was hampered by the gear selection problem and could not resist Bob Wollek's Courage WSC racer. After having a car in the lead for 21 hours, the DPR team finished third.

Fourth place fell to one of Bellm's Gulif-ivered McLarens (below), operated out of Cranleigh by GTC Competition under former EMKA Group C constructor Michael Cane. This car started We// with E strong double shift oy Mark Blundel, but then the team owner crashed in the Porsche curves. The repairs consumed 45 minutes. The Lotus F1 driver and Maurizio Sandro Sala did what they could to retrieve the situation, and the car reappeared in the top five at half-time.

After Pierre-Henri Raphanel had been delayed early on by a puncture, Philippe Aiot was also quick in the other Gulf car. Just before nightfall in fact, when the track conditions were at their worst, he passed Mass to take the lead. Forty minutes later, Alliot was clipped from behind in the Porsche curves by a GT2 Porsche he had just overtaken, and punted into the wall.

The French-entered McLarens were not equipped with the full e Mans kit and raced with ferrous brake discs. Giroix Racing, run by Thierry Lecourt out of a south-eastern Parisian suburb, used a synthetic composite fuel here, based on alcohol distilled from beet. Its owner started but could not fire the engine after his first fuel stop, at a cost of 18 minutes while his crew replaced the starter motor. Olivier Grouillard and Jean-Denis Délétraz eventually hauled the car up to fourth, but finished fifth after a Sunday morning brake change. Bello's, run by BBA Compétition from St Ouen, was also delayed early on, by a broken gear selector that cost almost 40 minutes. Marc Sourd, Hervé Poulain and Jean-Luc Maury-Laribière could rise no higher nan 13th.

Afterwards the race winner was proudly taken back to Woking. where McLaren continued to deny that it had been a works entry, while the Lanzante team prepared its Porsche for the rest of the BPR series. Nielsen and Bscher went on to clinch the BPR title to conclude McLaren's fantastic maiden season in European sportscar racing.
