But i always remember 510 because that what it actually has once it was setup in the motor and measured. Do run the .022 valve lash? My turbo is a bitsa i got made to what i wanted, its a Gt4294, but with a 71mm borg warner billet wheel. Same size as the gt4294 wheel roughly that flowed 850hp that i had, but this flows 925hp at same rating and i think 975hp at 30psi, as its a high pressure wheel it loves boost. Gt4202 flow 950hp at the same rating as this ones 925hp. i just wanted a good pump fuel turbo and this in the states is meant to be the best (precision basically sell it as a 71GTS). if i wanted to drag it, i would have gone for a 76-80mm turbo(probally a 78mm) How long did JPC take to do you mani etc, they took 12 months to get me a intake mani modified with the 90mm throttle body..crazy cheers darren Some original photos have not been recovered yet.

im running .016 rocker clearence as recomended on the cam chart .022 is way to loose.. its got about 530 thou lift. I brought my intake manifold secondhand but new! cant beleive you had to wait 12 months!

Mine says .022..., but that sounds excessive, will be giving Mark a call to ask him what he sets them to before i start it next century..lol cheers darren

hey, how did u go with the tune that was already in the autronic i sold... do many changes?

im pretty sure it was all changed different timing curve etc etc

it had 28 degrees timing all over jake was like it hadnt been touched

wat do u mean?

it was 28 deg across the board it didnt matter if you were at 2500rpm or 8000rpm it just had 28 deg no variation at all

28 degrees of timing and 35-40 pounds of boost, lolz that would be funny KKKAABBBOOMM cheers darren

timing and tune was done by jpc and u never see there cars blow up, every tuner has there own ways... tune was rich, and was a part failure remember, not caused by the tune.... afta wat corran told me tho it is interesting to as y they set the timing that way?

man 28 degress timming is epic!!

this might be the stupidiest question in the world, but it is possible for the comp to reset it self after not having power for so long etc?

It was full of C16 wasnt it Jake?

It had c16 in it, not bloody methanol..lol, this is the bit your all missing... HOW DO YOU RUN 28 DEGREES OF TIMING AT PEAK TORQUE WITH 40PSI...ROFLMAO( as it had 28 degrees everywhere), not just at peak power at the top of the rev range where there is less cylinder pressure cheers darren
