can anyone help me with this i am looking on andy forrests web site with regards to a 20g on my uk turbo can anyone tell me the sort of torque figure to expect from this turbo and what clutch would be suited to this am am looking at a exedy organic clutch but been told it will only hold 350/ft anyone done this regards scoobzie

 

With regards to torque this turbo is capable of well over 350 ft/lb, speak to david at API, he does a hybrid API/Exedy clutch which is proven up to 400ft/lb, at a very good price

 

Try Knowlsey at Xtreme Scoobies, they offer good clutches, my preference is with the AP Racing organic, and several levels are available to suit power / torque,

I'd avoid Exedy as I had a Subaru dealer fitted one which juddered from day one and I was fobbed off by dealer - it will bed in, etc. - but got money back when I took them to small claims court!
Other Exedy ( hiper single inc. light flywheel ) I had juddered too ... so I seem to be unluck with Exedy.

 

i have a td06 20g fitted to my car. its running app 400-410bhp and i had the ap organic clutch fitted. clutch is more on off than standard but it was easy for me to get used to and is still ok round town etc. works very well with set up. i had my work done at api.

 

exedy have released a 5 spring high performance friction plate that now iliminates the judder .

 

I've (well JGM, really), got 392lbft from my car (td05-20g and 10% E85). Running on an API uprated exedy clutch with lightened flywheel at the moment, seems to hold up OK so far, but I've only done about 150 miles since remap

 

Mine is not taking 420-440ftlbs and has just begun to slip. This is not a complaint, it has just been taken beyond its limits.

 

out of interest, what gearbox are you running?

 

A very anxious WRX 5 speeder.

 

lol like mine then

Are you running funny fuels to get that kind of torque out of an 18g?

 

I'm running 360bhp / 330 lbft on an Andy Forrest 20G at the moment,will hopefully be higher in the future,boost drops to only 1.2 bar above 6k rpm,should be holding 1.6 bar !

I've got an API Exedy Organic Racing clutch and API lightened flywheel which has no judder and feels excellent. I've been running this for about a year with no issues at all

 

No, but I do have 500cc more than I should...

 

i have the small exedy clutch in my car (the 225mm one?) which iirc was designed for uk classics?

its running 390lbft on a 16g

fwiw i would rather the clutch take the grief, then the 120k miles 5 speeder

 

How did you get 390lbft on a 16G ??

 

2.5 sti shortblock and then whacked the boost right up and mapped it to within an inch of its life




300bhp/350lbft at the wheels, i suspect the bhp at the flywheel should be a little bit higher as its not showing much in the way of transmission losses!

have another run done just before this one that was just wheel figures only

was also running a 0.1bar boost less on the rollers compared with the road

 

Have this set up and its just the standard organic running 368lbs
