Im not dogging you or anything, but I had 1999 Ford Mustang GT, I had a CAI, Patriot Stage 3 heads, Comp .500 lift cams, Typhoon three piece intake (ported and polished upper and lower) it was punched out and stroked to be a 306 (as opposed to the 281) I also had an NX 150 shot, and all necessary mods for that, ( Forged Rods and Pistons) and the whole msd ignition system as well. A Sachs stage 3 clutch, Built Tremec T45 Tranny, 4.10 Gears and the IRS from a '99 Cobra.
So you're saying that with your mods you are pushing 410 RWHP out of an auto tranny. ... it just seems odd to me, because with all my mods untuned I was pushing maybe 360 HP, Tuned off the bottle 425, and 575 on the bottle was obviously projected... ( never sprayed it, it was fast enough) Now, I was a mustang guy for years, and I know that the 4.6 modular motor will not make 410 RWHP off of A pair of generic heads, (even tho they are a good brand, still not particulary mustang specific) An FR Intake, MSD Ignition system, and Headers and CAI. They come stock with 260 or so HP. Without the stroke, the manual tranny, or the Cam, I just dont see it happening.
Now I know the truck is much heavier than a Mustang is, but 13.7 out of 410 HP is means one of two things, Youre either eating your tires all the way down the quarter (but with a trap of 111, I dont think thats the case) or your truck just doesnt make the numbers you say.
Untuned I could run a 13.1 @ 106.3. and spin that beast all the way through 3rd. (Street Tires) Tuned I ran a 12.03 @ 114 ( Launched with Drag Radials.)
Like I said Im not calling you out. I just dont see how you spent way less money than me and are making as much power as I did. Before you question how any of it was built, I can assure you mine was a quality build, and my tune was awesome.
I think Im just jealous lol.
