500bhp

[cossiedavid]

is there many of you running 500bhp on std comp

[Craig H]

is that possible

[jeardley]

hahhahaah no mate

[warrenpenalver]

I thought the big tuners were moving away from low compression on YB as the "standard" thing for higher power units??

[Tore_TJ]

of course it's possible! there's yb's with comp as high as 9 and above with more power. Mark Shead isn't running anything below 8 these days afaik. Correct me if I'm wrong on the last one though. Low comp is the safest and (maybe) the easiest way though.

The last wrc cars ran a high compression did'nt they. They done so for a more rapid response out of corners etc,

[FletchCossie]

Hasn't CossieRich off PF got standard compression (and even bottom end I think) running near 500?

[Paul RS]

Think he has 450ish bhp with a GT 30, standard head, standard bottom end but MAD's own spec cams?

surely he has valve cutouts for marks cams

[Kelv]

Yes Rich's is more or less a stock bottom end, other than the piston crowns having the suitable cut-outs to accomodate the cams/valve lift.
His turbo is an internally gated GT3071

Depends on the management your running , as newer ecu's can be mapped more acuratly to stop det ... erm or summit.
Mark shead did tell me this when we went there with Dan's car but , it was a while ago and im a little hung over today. lol

[cossiedavid]

thanks lads i have a L8 to run 8 injectors roller t4 hart inlet plenum with 8 greens 16 inlet cam 14 ex cam big ported head

[cosmagedon]

It is possible like loader says if the management can keep up with it so to say. Ive dropped mine to 7-8-1 for 500 as per Harveys instructions and thats going with pectel
