HP guesses?! Building my 3V!!!

I also agree on the HP for the street. I have mine tuned for 500rwhp for the street and still need DR's for real traction. I also have an auto, which is much easier to drive with high HP than a stick.

Man y'all should talk to my buddy who has a twin charged c4 vette with 1200hp that he takes on the power tour! lol but I agree too much power can be dangerous so just have to cross that bridge when I get there.

My Bullitt had a similar build. I had a new JDM stroked block, Ford Racing (Livernois) stage 3 heads (bigger valves and higher compression than stage 2), VMP TVS 1900 blower pushing 15psi, etc and put down 643hp on the dyno. Ran 138mph in the quarter low 10's.

What cr did you end up with? Full weight car? Your 138mph trap was on 93 octane? What rpm did you spin the blower? I'm only asking because I also have a vmp 1.9, 9-1 compression motor, comp 127550's, limiters, stock heads, 14psi(stock lower with griptec 65mm upper). The best I could get so far on 91 octane is a 10.6 at 128mph (1.47 60 ')...with a 35 shot! Lol. Did you spin the blower past 18000rpm? I'd like to run an OD lower but not if I'm going to get diminishing returns. Tuning for E85 with Lito right now so I'll see where that gets me. Thanks!

It's been so long I really don't remember specifics. Although I do think I had an oversized crank pulley, otherwise I couldn't get a belt that would work. Next size smaller would have been way too short.

Lito did try once or twice on tuning my car at my request but I went back to Justin. We were trying to work out low speed drivability issues and Lito was willing to help because he originally got started with SCT software from Justin. If he still has the files he may be able to tell you what I had specifically. I don't remember.

What year is that F-body in the background? I have a 76 F-body (pontiac) that I'm building right now.

What drivability issues were you having? I'm having an issue right now with a lean tip in from a stop at light throttle. It clears up around 1500rpm and then it's fine. Happens since switching to a return fuel system

little off-topic, you can guess HP by multipling the MassAirFlow value in grams per second times 1.2
And there are some Dyno apps for phones avaliabe which are pretty much accurate.
