2007 GT vs 383 HSR
My neighbor has been talking smack to me and all I can get from him is that its a S/C GT Stang with full exhaust. I know if I cant cut my ET to my goal of 12.00 I have no chance of taking this guy. He claims he has 500 fwhp...but i have never seen a dyno. Arent those things alot heavier than our cars??

Re: 2007 GT vs 383 HSR
.... its a S/C GT Stang....
Does S/C = supercharged? Not C/S for California Special, correct?
He claims he has 500 fwhp....
fwhp? Front wheel horsepower?? It is possible to get 475 rwhp with an intercooled Whipple with the stock 3.375" blower pulley. There are smaller pullies....
if its the gt500, its got 450whp i belive....
The GT500 is factory rated at 500hp. The '07s make around 420-425 rwhp stock. The '08 is rated the same as the '07 but they are making 440-445 rwhp.

My friends blown 07 GT pulls very hard. Me and my other friend were in his GT500 and raced the S/Ced GT and he walked slowely on us.

Re: 2007 GT vs 383 HSR
I currently own a intercooled Whippled '05 GT (5-speed) and a stock GT500. Although the cars share the same body style, each feels uniquely different so it's hard to make a true comparison BUT I'll try. The '05 GT feels like it pulls a little harder.
Flywheel, okay..... The intercooled Whipple kit advertises 500 hp.

Re: 2007 GT vs 383 HSR
Mid to upper 12s on average, a good driver could put it in the lower 12s, but the mph will be significantly higher than 107 which is where he will get you.

Re: 2007 GT vs 383 HSR
you should have more in that car than 107mph. i think you need some tuning work and then hurry up and put that bigger cam in there.
as your car sits, i think he's gonna get you depending on the boost he's running and his kit. I do believe there is one at my track that was cutting mid 12's at 110-112 mph.
a vortec blown 04 GT was there doing 11.70's at 116... he had some boost in that car and is abit lighter than the 05+ gt's.

Re: 2007 GT vs 383 HSR
yeah you may gain alittle with the bigger converter but i dont think it will be much more than 2 mph or so.
cuz with a 1.7 60 foot or a 2.0, i still trap the same and a converter generally just helps ET and mph doesnt change a whole lot. sometimes it will decrease mph

Re: 2007 GT vs 383 HSR
you have shorty headers on a 383? arent the edelcraps only 1 5/8" as well? your without a doubt leaving a huge amount of power on the table with that exhaust setup. definately get some long tubes with 1 3/4" primarys and a larger catback (although id run cutouts behind the longtubes and just bypass whatever catback you have when you go to the track). youd probably see 3 - 4 mph with an exhaust swap
where is stafford VA? i want to run one of those new blown Stangs in my Vette but i cant find on around here. id run him for you if youre semi close
25th, what does a GT500 pull mph wise?

Re: 2007 GT vs 383 HSR
Which C6? the old LS2 or the new LS3?
114mph huh? thats what i trapped in my Vette untuned. havent had a chance to run it now that its tuned (Cecil opens in late Feb) but id expect it to do a bit better
i figured itd be a good race... now i gotta find one. however, the chances of ANY GT500 running stock boost tho is probably slim to none!

Re: 2007 GT vs 383 HSR
In the FL heat, my friend's 100% stock 07' GT500 made 406 RW, trapped 109. CAI & tune, 480 RW - 12.20's @ 118+ w/ drag radials.
Another local 07' did 423 RW with more miles, 505 w/ CAI & tune. 13.30's @ 110 stock, 12.00's @ 119-120 modded. Both cars are on par with the rest I see at the track in Orlando.

I thought about doing the cutouts and not even trying to do the true duals or single 3.5" catback for cost reasons, but I cant find a mechanic that would pass me with cutouts on there.
