Hey all, I'm new to the mustang world and was wanting to know in a ball park range as to where my car falls in the hp. I have a built 306 from ford which I believe to be the 340 hp. My engine specs are Powerdyne supercharger with to my knowledge is running 6 psi (haven't measured pulleys yet) 80 mm mass air, 75 mm throttle body, 42# injectors, gt forty lower intake cast upper, gt 40x heads, Forged pistons, b31 cam, Long tube headers and a 255 fuel pump. I was thinking maybe around 500 rwhp???What do you think?

 

I doubt your even close to 500rwhp. More likely in the low to mid 300s

 

Ran the car at the track last night. 7.69 in the 1/8th with this set up. Forgot to mention before stage 3 clutch backed by a 4 link eaton posi 3:73 gears hooked hard for 3 to mid 300 hp.

 

Sounds like mid to high 300s,depends on compression too. Put it in a dyno and know for sure!

 

Welcome to the forum, and congrats on that Mustang. But I have to agree with the above posts. Your not anywhere near 500 at the wheels if your running 6psi. But for reference only my car ran 7.94 @ 87 with 300 at the wheels. There can be alot of variables in ETs, but the mph will give a better estimate of power. You could post this exact question in the Street/Strip forum, along with a pic of the time slip, and we'll get you pretty close. Plus your race weight.

 

welcome

go to a dyno and find out.
