Congrats. Great looking car and great numbers for the street. By the way, I think you technically now have a stage 3 CJM fuel system

seems like a lot of boost for that power. I would think you could make that power at ~15 psi...?

It's not what you might expect because the kit is out of breath and making peak power at 5krpm.

Looks fun, enjoy OP.

Looks fun, enjoy OP.
the 700 should have similar sized turbos... maybe even slightly bigger than the standard aps turbos. GT28/86 vs GT28/71. my car made about the same power at 15 psi with the aps kit. Obviously different dynos and my car is 9:1



I am not up to date with recent parts, but cometic doesn't have a good rep from the research I have done. Is it a specialized spec?

Turbos might be similar but everything else is different -- the piping, manifolds, downpipes, everything is different than the APS which breathes far better than the JWT kit. You've also got a bump in compression ratio which adds almost 10% more power given ideal conditions. That said the OP has put down solid numbers for that kit and it looks like a blast to drive.

congrats Robert,

i have very similar results. i just tuned my car last week and except i have BC 272 cams.

JWT 700BB
BC 272 Cams

581rwhp on a Mainline Dyno 18psi drops to 16 psi. i think my haltech solenoid is not working as i was trying to bring boost up but didnt work.
