what is the max power you can get from a t34.48? what difference would .63 make
running greens?
running greys?

depends on lots of things:

what psi you run obviously, whats the full spec? also you might be able to make it do the numbers on the RR but how long do you want the turbo to last

the turbo will out flow greens at around 350 ish

also greys will out flow the turbo

as an example i "think" james as MSD got 370hp and 420lbft out of a t34.48, but he ran 35 psi boost (spike) - but im not sure what the rest of the spec of the motor was (cams, inlet, head etc)

Mine made 363 when i had it Dyno'd on Greys, Leigh who bought it off me afterwards had it Dyno'd @ just 340, but has for your question, some on here have seen 380 on them so again, who really knows??

at the minute its standard 4x4 head, wrc gasket, skimmed standard pistons 200 block, greens, t34.48, 500i/c. but once i finish getting the engine out and send it off the bottom end will be rebuilt with standard comp pistons with valve cuts, 10 long studs.
was thinking of changing to .63 but just wondering how much i could get out of .48 with changing injectors

if it was me with that spec i would stick with the t34.48 or if you do want more power than ditch the t34 and go for a gt3071, with a set of greys or siemens you'll see 450+

the cost in changing the exhaust housing for the amount of power increase isnt worth it IMO

I just got back from ava and my mates saff made 341 atw with a tt t35.55

Ava said its the highest powered t35 they have seen on theyre rollers.


Very good specced car with msd sofware, seimans etc.

The things a rocket

i can have a wrc spec quick release .63 for £100 off the bloke who does my engine. what difference would it make to the power curve of my engine?

mine on a .48, but havn't had it rolled, its running enough to run 12.4's @ pod though (fully trimmed with stereo install),

My old standard engine did 358bhp at 2 bar on a t34.48

WongRS

thats what i expect from mine kev, although some people in the know think it may be more.......knowing my luck, it'll be about 260 though.

What's your spec dan ? Ive just got a rollerbearing t38 for mine.

standard lump, apart from head has had secret fettling i found out about the other day (lad who skimmed the head let the cat out the bag the other day when chatting to a mate of mine, he loves YB's, builds alot of NA ones for grass trackers, and got carried away with mine, but didn't tell me or charge me for it!)
usual stage 3 gubbins, bar 55's and 32 psi peak, 26 hold, coil packs and closed loop.

circa 400hp with a .63

I'd say around 360 then dan.

WongRS

iTrader: (11)

yeah, thats my guess mate, pulls well whatever it is, not really into number chasing, thats why its never been RR'd.

KSA-Cossie

yeah, does suffer a bit of spin! think it wants softer springs on the back to help it squat a bit.
