Default New dyno #'s. Track times coming soon

Dyno tuned the new setup. Same shortblock as last year but now has AFR 235 heads, Super Vic intake converted for EFI, 4-hole 2000 cfm throttle body, dual stage fogger/plate nitrous.


Motor only results (n/a)

538rwhp 493 rwtq ....this is with very cold #9 spark plugs gapped at .025

Nitrous results 1st stage only

824 rwhp 854 rwtq



Did not have time to tune the 2nd stage yet.

I thought AFRs were trash!!!

Killer numbers. Are those 235s as cast or were they touched up any? Was the supervic worked over to match?

I hear the supervic can have some nice gains with hand porting .

They are untouched in the CNC'ed runners. Only thing we did to them was convert them to reverse flow. Supervic was ported by Lloyd Elliot and converted to EFI by Charles Bourassa.

I can't imagine what it would do N/A with #6 heat range plugs and a more aggressive n/a cam. Hell my cam has a 114 lsa! lmao

nice job tony! that's a lot of valve you're running, small bore is killing you quite a bit I'll bet. Mind spilling the lift numbers on the cam?

I cut the cowl this year. Have not had it inspected in two years. So no...it does not see street time anymore. 2008 and prior yes.

from my experience... you're not really gonna wanna daily drive something like that. Trust me the compression/cam required to make that power make the car loud and drink gas. Make you're own thread instead of hijacking his ****.
