hey, thats pretty cool looking


how much boost are you running now compared to when you were non-intercooled??

Formula

I think there is something wrong with my boost gauge because its saying 7 (I added a 3.4 pulley, intercooler, headers and the power pipe), and it was 8-10 with the brenspeed kit depending on the weather. When I was at the drag strip and ran the 12.9 it only went up to 5. It was over a hundred degrees and I hot lapped it 4 times.

My gains were:
Stock @ 5800 rpm: 230hp
Brenspeed @5800: 340hp
Brenspeed @6400 (3 months later - so broken in): 360hp
Now @5800: 430hp

These are all on a mustang dyno and corrected, it is about 15% lower than a dynojet.

your base numbers seem low. Were you running the 8 psi standard non-intercooled kit??

Maybe you were still pulling boost??

Formula

yeah, it was the 8psi kit.

On the same dyno an eforce made 360 so its numbers are pretty low. The big thing to look for is the difference in the initial reading, I'm 200whp over stock now so I would probably be around 475-480 on a dyno jet.

damn.. makes me wonder how much power I am really making..

sure dosen't feel like 400whp, more like 380ish.. maybe less even at the advertised 8 psi canned brenspeed tune, though I do only have 90 oct (tune) up here..
