damn this winter!

how much horsepower you guys think I am running without the nitrous?

 

i think you will see a nice gain, but you really need some heads to make good use of all of your other performance parts. I am sure you will be well into the 13's. Put a sticky tire on and you will be surprised.

 

I hope I can break in the mid-high 13s.
I have another engine that came with my car that was suposedly rebuilt, and the heads look like they have new valve seals and stuff, would it be worth the hassle to port the exhaust bumps and put these in? or would it make a difference, sometimes at idle after racing my oil pressure goes down to 19psi. could it be from leaking valve seals, or jsut a worn out oil pump?


do you think I will break my rear suspension?
I looked at my torque boxes and they are a little messed up.
I couldn't fit my reinforcements in yet.
I still have stock suspension.

Bone stock - 10.5s


LOL

 

Well, this is the what I ran before I got good heads, and a pro m 75mm MAF, and an adjustable fuel pressure regulator. and I was on a worn out *** drag radial launching pretty easy cause I had a long drive home:

Rebuit engine E303 cam, Lontubes with offroad H and flows, Ford Racing GT40 Intake and #24 injectors, 65mm tb,stock MAF w/ adapter, MSD 6A ignition, upper/lower control arms, King Cobra Clutch, 4.10 gears, gay *** K+N cone filter sucking hot engine compartment air, B+M Ripper Shifter, Ford Racing wires and MSD cap and rotor, I think thats all I had at the time and I ran a 8.62 in the 1/8th @ around 82 or 83 mph. I used an ET calculator and that translates to 13.2 @ around 102 mph in the 1/4 mile. I want to run at a 1/4 mile track this summer and I hope to be into the mid 12's with my new heads, roller rockers,maf, and afpr.

 

You launched at 4k RPM with 4.10's in an otherwise stock rear end?? HOW!!?!?!? Let me know!

 

I ran at the track again and my best time was 14.3 @96mph.
without my nitrous.
I am scared to try it untill I fix my torque boxes and get subframe connectors.
