yes but if you choose to have an heavy unstable car its becouse you know that its more important to have the possibility to draft. in real life, on suzuka, if you lost 1.5 seconds in the esses you are in trouble. no one would choose 10hp and not downforce
The amount of downforce you had is equal to more than 10hp. I was pulling away from you on every straight even when you were drafting me. If you didn't have my draft, you would have been 3+ seconds behind after the two straights. Any racer would gladly take that extra power. It is extremely difficult, if not impossible to cleanly pass on the esses without contact if the driver in front follows the proper racing line (which I was doing until you tapped me and forced me to lift off the throttle). With 450pp racing, you can't be fast on every part of the track. Compromises have to be made between weight, power, and downforce. Your tune allows you to make up time in the esses, but it offers no ability to pass in a straight line. It gains you about 2 seconds per lap but when you are behind someone you have no way to get around except to push them out of the way.

You weren't gaining position. You were temporarily gaining ground only to lose it very quickly afterward.
I get that completely...but your original comment said you didn't find much difference at point "x" which lead me to conclude that my divebombing was in fact a fast line through turn 1 allowing me to gain track position. I assume the two laps you were referencing did not include a draft right? Also, you had more ballast than me and thus more hp...which could count for something as well.
 
i drive with a wheel so i try to tune for stability, good weight transfer "flickability" and good power delivery. I started firming up my spring rates but i often forget about the weight reduction and ballast affecting the spring rates. But this car was well sorted.

Video from GVE-R from my bumper. Grenade and I can argue about who's line is faster all we want but I see myself gaining tons of ground on lap 3 and 4 through turns 1 and 2 without losing any ground going up the hill. You can claim its the draft if you want but its clear in other parts of those laps that the two of you could pull away from me on the straight. Of course, my high speed through turn 1 is very risky and prone to running off...as noted by lap 2. But I will continue to run it when I am not challenged from behind.



A few of my blunders...

I apologize to Mike and Rockin for lap 2. After going off, I stayed outside to let Esh and Grenade by. Then I hit the gas to get going again. I spun one of my tires and it caused me to fishtail up the hill. I think the two of you were planning on going to my inside before that happened.

Lap 6 I hit Esh by accident. I think I was talking at the time and forgot to get off the gas...it wasn't intended to be a pass...I just forgot to brake. I slowed up to make sure he got back going again and we continued our battle with Grenade.

Well, I had a detuned car in hopes we would have run some faster tracks. I had 288 hp. Probably only 4-7 more then you. My hp/kg was probably lower then yours.

You were definitely gaining track position. You basically slide through those turns using 100% of available grip for turning. This allowed you to gain on me as I went into turn one. Coming out of turn one, you slid to the outside still losing speed. Whereas, I braked and then accelerated.

I am comparing what I saw as your fastest turn 1 and 2 to my lap 8 turn 1 and 2. I hit 73-74 through the apex of turn 2 and you hit 71-72. I should have been quite a bit faster through my "x" point but it seems you actually out accelerated me or equaled me.

Basically, it looks as if your turn in on turn 1 is much higher then mine which causes you to go a bit wide on turn 2. Not much. Just a little. You weight is still on your right side when you begin braking which is why you continually go wide during the laps.

My turn in is substantially more subtle then yours on this turn. We both accelerate out of it. Since my car is flatter through turn 1, I don't run wide into turn 2 and hit the apex and gain more speed.

Then looking further into my "x" point (another 10-15 car lengths past apex of turn 2) you have caught up some time despite having a slower apex speed. I attribute this to your better hp/kg ratio then my car. We are talking 1-2 mph here, but sometimes that changes .1-.3 seconds.

Technically I can quote the same thing on laps 8 and 9 where I caught up to you substantially through turns 1 and 2 even though you ran them cleanly :) GTP_esh stayed basically the same distance from you throughout laps 8 and 9. Yet, I gained substantially on you both with no draft. Look at GTP_esh mirror going into the final straight on lap 8, then look at it after the tunnel. Also, look at where GTP_esh was compared to you after the uturn after the tunnel on laps 8 and 9. He basically stayed in the same relevant position to you, but I went from being barely in his mirror to right on his ass. :)

This is concrete. I was 72 at best when I hit the apex right. When I missed it, I was down to 68. If you can achieve 74 as your slowest speed at any point then you've got a faster turn 2 for sure. I'll load it up and watch your replay at some point to see.
 
Man, I just did not have the acceleration. Like I said, I wasn't the best through the corners, but I see myself in your rear view just fading. Oh well.

Looked like I was lagging quite a bit, not sure what I was doing on lap two either, looks like I was being a bit aggressive.

I think lap 6 was my fastest. Lap 8 is a good example of a clean line (not the fastest I don't believe that I ran). I wasn't 74 at my slowest point. But I was in that range and up to 74 at the same point you were 72.
 
I was terribly slow through turns 1 & 2 laps 9 & 10, which would explain the gain in position. I didn't average nearly the same lap times those 2 laps as I had the previous 8.

Overall it was a great race though, and the competition was tight between the 3 of us. I had no way of passing Esh while he was in grenade's draft so it was good practice for me in following closely behind.
 
chuy - Can I please get the ghosts as well? Thanks
 
Good, that was the point. I don't like the way you race and while there was some kind of lag glitch at the point i went off track, you were driving dirty for laps before and after that. I'm just ignoring you from now on.

I think i possibly had the fastest car last night but rarely had the consistency for it to pay off. I ran a 1:23.x in qualifying with a bunch of errors and my last lap i was .4 up on wii or AOK, whoever had the pole, but everyone was ready to race so i quit to the pits. My tune:


weight reduction 3
chassis reinforcement
ballast 160kg at +50

Engine tuning
Engine stage 3
power limit 99.9%

Sport manifold
Sport cat
Ti race exhaust

custom trans 199mph top speed
twin clutch
semi-racing fw
diff stock settings
carbon drive shaft

Suspension
-4/-4
7.5/7.4
4/4
4/4
4/5
camber 1.0/1.0
toe 0.00/0.20
brakes 5/3

It was stable and fast. Nic was battling with me in the first few laps, it was a quick car.

i hope that 16 in your nick stands for your age

im goin to host a room if nobody else will do it. 450pp comfort soft like the other week
 
Ive got a 450pp comfort soft room open for a while if anyone wants to join
 
whats the room number? i can't see you online in community
EDIT: oh nvm, found it
 
Room number pls.
 
nmcp1.. it will probably be chuyler's private room so you need to send him a FR.

tried that already but he's got quite a few friends.....:)
 
Sorry, it was a pub rm, i'll post the num next time. I had to remove some friends from my list. If i removed you just send another req or msg me and i will add you back.
 
Any suggestions for themes next week?

I have a request pending so when you get a chance. Looking forward to getting in on the action.👍
 
Regarding themes, have we done trucks in a while? ff cars? Kei cars? Roadsters excluding S2000/Miata?
 
In for wagons, but we would have too make it fair. Maybe a 420pp wagon race? That would open it up from 4WD and one FR wagon (unless there is something besides the IS300 wagons??) to finding the Lolvo wagon, and maybe some FWD stuff.

EDIT:

Kei cars night sounds awesome, as long as its not just the Capp, we might have to drop its pp as well. So the Beat, and the FWD Daihatsu (Cuore?) can get in. Just a suggestion.
 
How many wagons are there? I can only think of 2-3. Volvo, Lexus, and i think there is a Mazda6 wagon?
 
subaru and audi
 
oh yeah, forgot about the audi and subies
 
With wagons, the scoobies dominate...but we can try it

Keicars are tough. Even though they all look competitve on paper, some are way faster than others. Last time we tried it, boost was required.

I'm definitely up for a open FF night. I'll make the schedule tomorrow.
 
i have done a test on daytona speedway to see how much speed you loose with a wing and the result was that i was FASTER with a wing. only 0.100 sec but still faster. i have set up the wing to 10 so the loss of hp was about 12. in the straight the cars was running togheter. this with a spoiler set to 10. my silvia the other night was set to 5, so its all about draft. if you have 15 or 20 hp more you can be slower by 2 seconds in practice and still have the chance to pass on the first straight. this sucks

What were your specs for the tune (Silvia)? I was about half a second off the fastest lap time, maybe a little more, and was getting drafted and passed quite easily by chuyler and grenade but wasn't ever really able to draft until the very end of the straight. It didn't matter if I had multiple car lengths on them.

I would be curious to know what everyone's hp/weight ratio was.

On a side note, I purchased an HDCP compliant graphics card, as well as an HDMI capture card, and will try to record some replays. Here's my pov from GVE-R in the Silvia. I built my desktop in late 2006 so the quality isn't going to be HD but it's clear enough to see. Don't really understand why the quality is so bad when the .avi I made is over 1GB in size and looks great before it goes up to Youtube.
