I was bored one night, and felt the need to learn a little more about the performance upgrades, so I went through and read the details. I was a little weirded out to see that for higher powered vehicles the twin plate clutch was actually better.

Compare the two details. The Twin Plate Clutch says, "This racing clutch kit features dual clutch plates, ideal for high-torque, high-power vehicles." After I had enough money for anything upgrade I wanted I would just get the highest settings (except for the LSD, I typically get the 1.5 Way because I suck with settings). While the Triple Plate Clutch says (this is towards the end), "This kit is ideal for non-supercharged engines with a narrow torque band, for instance, rather than highly-tuned cars."

Am I just really dumb and the rest of you already knew this and bought the appropiate clutch? Or am I reading something wrong? Eh? EH!?

PS - Sorry if this is a repeat
 
I did some tests, and it doesn't really help me. :P

I took a few cars. For all of the tests I used the same car, same settings, while the only difference was the clutch. I also used an automatic transmission and just floored it the entire way down the 400m and 1000m. Here are the results:

Fully modded Supra with a Twin Plate:
400m: 12.049
1000m: 19.561

Same Supra with Triple Plate:
400m: 11.791
1000m: 19.460

Hrm. Seeing as how it says for high powered cars, and this is running at about 1060hp, it gives a good example. I guess all thats left to say is....

NEVERMIND!
 
You can't pay attention to everything the descriptions say. Triple Plate is always the best, just like Racing Flywheel is always the best, just like Racing Muffler is always the best (except I think there's some kind of bug with the Beetle on that).

Now, my testing methods may not be the easiest thing to wrap your head around but check this out:

Code: 
Audi TT 1.8T quattro (232.3 base HP)
	Oil				   250	221 -> 232HP	  5.0% =   50cpp

	Turbo Kit/Stage1		 4,800	232 -> 252HP	  8.5% =  565cpp
	Turbo Kit/Stage2		13,500	232 -> 267HP	 15.5% =  871cpp
	Turbo Kit/Stage3		42,500	232 -> 325HP	 40.0% = 1063cpp

	Intercooler / Sports		 1,800	325 -> 338HP	  4.0% =  450cpp
	Intercooler / Racing		 3,000	325 -> 351HP	  8.0% =  375cpp

	Muffler & Air Cleaner/Sports	 1,600	351 -> 365HP	  4.0% =  400cpp
	Muffler & Air Cleaner/S.Racing	 2,900	351 -> 372HP	  6.0% =  483cpp
	Muffler & Air Cleaner/Racing	 4,800	351 -> 379HP	  8.0% =  600cpp
	Port Polish			 5,500	379 -> 394HP	  4.0% = 1375cpp
	Full-engine Balancing		12,000	394 -> 404HP	  2.5% = 4800cpp
	Racing Chip			 1,500	404 -> 416HP	  3.0% =  500cpp

	Lightweight/Stage1		 1,200 1395 -> 1297kg	  7.6% =  159cpp
	Lightweight/Stage2		 5,500 1297 -> 1241kg	  4.5% = 1222cpp
	Lightweight/Stage3		22,000 1241 -> 1185kg	  4.7% = 4681cpp

	Suspension / Sports		 3,200
	Suspension / Semi-racing	 7,400

	Clutch/Triple Plate		 4,700
	Flywheel/Racing			 1,050
	Driveshaft/Carbon		 3,000
	Transmission/Sports		 5,700
	Transmission/Full-racing	10,400

	Racing Tires/T2 Super-slick	10,500

What I've done here is show the % increase to the power/weight ratio that each upgrade gives. The last figure, "cpp," is the cost per percent, i.e. a Racing Chip costs 1,500cr and gives a 3% boost to HP, therefore you're paying 500cr for each 1% your power is improved.

I'm showing the Audi TT here because it's the one I did the most clutch/flywheel/driveshaft testing on. Here are the 400M times:

Code: 
	400M times (TCS 3):
	16.980	Stock 232HP
	16.781	+10% HP (256HP)... delta accel 16.980/16.781-1 * 843.27 = %power equiv.
	16.401	+40% HP (325HP), Turbo Kit/Stage3 functioning at 29.8% equiv.

	16.880	Stock + Flywheel/Sports			  450cr,  5.0% =  120cpp equiv.
	16.785	Stock + Flywheel/Semi-racing		  600cr,  9.8% =   61cpp equiv.
	16.727	Stock + Flywheel/Racing			1,050cr, 12.8% =   82cpp equiv.
	16.922	Stock + Clutch/Single			1,700cr,  2.9% =  586cpp equiv.
	16.844	Stock + Clutch/Twin Plate		2,700cr,  6.8% =  397cpp equiv.
	16.775	Stock + Clutch/Triple Plate		4,700cr, 10.3% =  456cpp equiv.
	16.693	Stock + Driveshaft/Carbon		3,000cr, 14.5% =  207cpp equiv.

	16.410	Stock + Flywheel/Racing + DS/Carbon	4,050cr, 29.3% =  138cpp equiv.
	16.249	Stock + Flywhel + DS + Clutch/Triple	8,750cr, 37.9% =  231cpp equiv.

What I've done there is show how the flywheel/clutch/driveshaft upgrades affect your acceleration, translated into terms of how much of an HP upgrade you would need to get the same benefit. As you can see, these upgrades are pretty much the best things you can buy for any car (unless you're on Test Course). The Stage 3 Turbo costs 42,500cr, but buying a flywheel and driveshaft for 4,050cr will give you almost the exact same improvement to acceleration. An Audi with 232HP and a clutch/flywheel/driveshaft is faster than an Audi with 325HP and stock clutch/flywheel/driveshaft. The more HP upgrades you add, the less of an actual effect it has on your acceleration, but the clutch/flywheel/driveshaft actually seem to work together to give you better acceleration than the parts do individually.

Therefore, if you're worried about money, the absolute best upgrade you can get for any car is a Racing Flywheel. The clutch/flywheel/driveshaft are always among the best thing you can buy for any car. The only other thing that is nearly as good a deal is Stage 1 Lightweight (and as you can see on the Audi, the Racing Intercooler is a very good deal).
 
*looks at numbers, feels penis shrink*
Ahhh nuts. :D
It's a little too much for me at the moment, I'll read it again when my head doesn't hurt. Thanks though!
 
Just a quick question, non relating whatsoever to the subject but what is "VG30DETT" is this some sort of motor cause ive heard of Nissan RB26DETT and RB30DET but never "VG" must be a North American thing???
 
interesting numbers there BBM.
I've always thought the flywheel and clutch were good upgrades and those numbers seem to back up what I've alway thought :)
 
The RB26DETT was the engine code used for the GTR 32, 33, and 34s. I've never heard of a RB30DET... Although... Was it possibly Top Secret's Nissan Skyline GTR 34? I read an article about theirs and I imagine they increased this displacement, but I remember they replaced the two turbos with one. None the less I don't believe it was ever produced by Nissan. I think I could pull some more Skyline information out of my rear if need be. :D

The VG30DETT is the engine code for the Nissan 300ZX Twin Turbo.
 
Ah it all becomes clear now. The RB30DET came out in turbocharged holden commodores i think??.
As for the Top Secret Skyline i dont know what the motor in that was.
 
Ehhh...
Well, see Nissan's engine codes are pretty easy to follow. RB26DETT breaks down into:

RB - Engine class, in this case, it was the Skyline. All Skyline trim lines had some sort of RB engine in them.
26 - The displacement of the engine. 2.6L in this case
D - Dual Overhead Cams
E - Electronic Fuel Injection
TT - Twin Turbo

So, the RB30DET would still be a Skyline engine, but they probably bored and stroked it out to make it a 3L. Then, the only other difference would be replacing the two turbos with one.

I looked up what a Holden Commodore was, because I had no clue. There was a link that said to look at V8 racing for more information. A RB engine is a straight six. So, thats just completely wrong. There could of been two very similar/same engine codes, or that Nissan sold their engines to Holden, or whoever. I'm not certain though.
 
Nissan made the engines for Holden Commodores in the late 80's early 90's the base models had RB30's in them and the upper models either had the RB30DET or a v8.
heres a picture of the car they came in.

lightweight flywheels are only non-beneficial of your shifting technique is lacking. in real life..the time that you spend with your foot off the gas peddle can drop out of the revs so quickly with a racing flywheel, that when you go into gear, the engine has to rev up again to match the tranny. this takes some of the speed away...but as for advantages, as long as you can shift fast, it revs quicker..and has a bit more hp due to the fact your engine doesnt have to turn as much weight. i have no idea what its good for on GT3 :odd:
 
Dad's cars' (my avatar) engine is a two litre single turbo. (RB20DET)

Carry on. :D
 
Until I found that website I only heard of them having RB26DETTs for the GTRs, and then RB26DET/RB25DET for the GT-S.

Bah! I suck!

thanks i never knew what they actually meant all those numbers and letters so that cleared it up nicely and dont u just looooooove the z's? :)
 
No problem. I like the ones that are easy/make sense. Some are just weird. Like a Hyundai Tiburon v6 engine code is "Delta". :P A Mazdaspeed Protoge is a "FS". I'm sure if you knew more about the car and it's history it would make more sense, but to me, they make no sense. I think Honda engine codes make sense. Integra's 1.8L GSR engine is a B18C or B18 I believe. The Prelude 2.2L is a H22 I think. Anyway, I just like those ones that make sense. I'm sure there are a lot more companies with them.

I like the Zs. I don't know too much about them. I chose this name because RB26DETT was already taken and 300ZXs are nice. I was thinking about buying one actually. Unfortunatly, the insurance company wasn't too hot about the idea that a 18 year old who already totalled a 1995 Nissan Altima GXE, wanted this 280hp, twin turboed two-seater. :P Insurance would of been about $450 a month. That coupled with the amount I have left to pay on my current car was too much. Gr!
 
It's nice being a 27-year-old who hasn't had an accident in 10 years. My insurance is $31.85/mo. It would be a little lower, but I've had a speeding ticket this year.
 
thats what yours says? i take it its a US copy

heres a snippit from the EU version.

"Clutch/Twin: Suitable for high torque, high power machines."

"Clutch/Triple: Ideal for cars with hard tuned engines."

keywords, 'suitable' and 'ideal'

Wow! thats really cheap. I don't know what car you are driving, but thats a good rate.
Mine is $104 per month but i do drive a skyline and im only 19, have'nt had an accident to date though.

I've got a Del Sol. Not exactly the sportiest thing, but insurance is higher for 2-seaters and convertibles (and they consider the Sol a convertible and not just a targa).

My last car was the amazing 1986 Chevy Sprint: 48hp @5100rpm, 57ft-lbs @ 3200rpm 1.0L 3cyl. It's the same thing as the Suzuki Swift. It also had 300,000 miles. The insurance for that was $14/mo.

WOW, thats cheap? I would kill to pay 104, Im 19 and I got an 89 bmw 325i 4 dr. I paid around 250 for liability. And as far as lightweight flywheels go, they're good and bad. If your drag racing like I do, lighter is better, but if you intend to downshift at all, you can forget it, make sure you got some big brakes.

How Paranoid of you.

Insurance rates are equally high in Australia, and you spend a total of 42 months on Provisional or Learner licenses, at least in my state.
