Well I calculated that using the same bmep and specific power as mine with the 270 cams. Working backwards to find power and torque, not the most accurate I know but better than picking numbers out of thin air

id be expecting 5/6psi and 10/20bhp with the smaller pulley.

well yes, but usually you get roughly the same percentage power gain as you have increased the cubic capacity by, so if you increase cc by 12 percent ,you will gain roughly 12 percent power and torque ....which is approx 20 bhp and 20ft lb torque.

not a bad gain that for a bit littler pulley drew, i think that's what garymgzs180 on here did, went for more boost from littler pulley and his is making good power.

raised the suspension a little, still need to do a bit more on the front. got some pics of the front arb and fittings..

Whiteline 27mm front arb..

made myself a front link up..

took a pic of the roll centre adjusters..

not a lot of space left with the brembodge on there. might need a little tweeking.

I used reduced diameter Nyloc nuts on the bottom joint cos they touched the disc otherwise.

Some good work going on there btw.

have you got your front camber arms on? that may help? mine dosnt need smaller castle nuts and thats fairly low.

Drew · 28-01-12, 07:12 PM

i do but havnt set the camber yet. more camber may help me, but i have roll centre adjusters that may be making it a little worse.

its still a little low so should get a few mm there.

oh well, one mod on, need another mod for it to fit, etc etc.

cheers
