i have a 05 plate hawkeye running around 350bhp, when i try launching off the lights i get a smell of clutch suspect it slipping does anyone else suffer from this or should i consider a better clutch? whats the next option as i dont want to go paddle, also genral hard driving the clutch is fine

mellinator

its your clutch mate.

Its normal to get that smell when your launching.

You have got to remember that you have 4 wheels trying to dig into the ground under hard revs.

I learnt the hard way and went through an evo clutch in 4 weeks!!!!

thats what i was thinking but didnt know what the next option was i dont want a paddle clutch as there a pain in the back side cheers mellinator

I sometimes get the same in my bugeye STI. I found it was because i wasn't being ruthless enough when dumping the clutch at high revs (ie above 4000). But the other problem I had was if I dumped the clutch when the revs were too low (ie below 4000) the engine completely lost power and a fiesta 1.1 could beat me off the line! So the only way round that was to slip the clutch. catch 22 or what

exedy organic clutch is a good upgrade, mine has been in for a year and attended 4 drag meets, last 2 at approx 450bhp and starting to suffer now when launching at 6000rpm & 1.3bar!!!

The subaru clutches are relatively small diameter and don't have much heat capacity, the key to a good launch is keeping the clutch slip at just the right amiunt to get it rolling without dropping the rpm into the offboost area versus slipping it to much and overheating it so it keeps slipping, the larger the turbo, the harder this is, having peak boost at 1900rpm is a big help!

rev the car more and dump the clutch in a fast motion, if it slips and smells its because ur not dumping the clutch quick enough!

or too much power

300bhp/ton

Yep the drawback of small displacement, fairly large turbo charger and 4wd.

You don't see many top level 4wd drag cars for a reason

An alternative would be to use nitrous off the line, this way you could have the nitrous take up the slack off boost so ultimately get a better launch but less brutal.

when you sort your clutch out, you will be asking how to stop all 4 wheels spinning on the line

try 888's

ill look at the upgrade option but idont want anything that makes the car a nightmare todrive ie a realy heavy clutch pedal

I was considering the AP Racing organic clutch. It says suitable for everyday use

Advanced Engine and tuning Products for your Subaru Impreza, Turbo, WRX, STi or P1

Anyone any thoughts on it?

im running the ap organic clutch with a ACT prolite fltwheel (4.3kg)

and it is good for every day to day driving, think i have only stalled it 2-3 time in the last 6 months, normally reversing lol

scoobyluke23

daone, how do you find it now yourve got a lightend flywheel any diffrent?

Ian

i find it normal to drive now, sometimes you have to give it a little bit more of a rev when pulling away, but soon get use to it.
worth doing

What a plonker: unsecured dog in the bag and driving like that!

To say nothing of the fact that that looked like a residental road with a 30mph speed limit: that kind of stunt gives us all a bad name!

Agreed but the the launch is a good'un, poor dog tho

I went from stock clutch to organic upgrade to ceramic button clutch. The best was the organic upgrade but it did smell sometimes thats why I went to the ceramic clutch. but it lasted around a hundred 5500 rpm launches and about 12000 miles.

The ceramic clutch works fine no matter how hot it gets but is a bit abrupt when driving normally.
