There is a guy around here local with a 98 convertible Mustang GT with the 4.6. He said his car pulled 530rwhp with shortys and 580 with longtubes. His mods as he told me are: Vortech S-Trim supercharger, intercooler, BBK longtubes and off road X pipe, american thunder catback(flowmaster), and 4.10s. He said he runs bf goodrich drag radials and runs 7.40s in the 1/8th and 11.70s in the 1/4. He said he usually 60fts 1.85s to 1.95s launching at 3500. Manual transmission. He said he has changed the pulley to up the boost to 12-14 psi, and that it sometimes will go up to 15 at redline right before the shift. I asked if he had different heads or lowered his compression to run that high of boost and he said no. He did blow his head gaskets last summer though. He said it was stock compression and everything. He said that it only has like 16 degrees of total timing whatever the hell that means. Someone shed some light on this whole deal because I saw on horsepower tv where they took a 4.6 that made 200-208 rwhp and added a vortech supercharger and it went up to like 280ish rwhp. I know he is running more boost but I still call BS. What do you all think?

i call bs. 580 rwhp and only high 11's? hes going to need forged internals and a LOT of boost to see that much power out of a 4.6. besides, 98's have inferior heads to 99+s, and i havent seen any 99+ gt's making that power with those mods. either hes bs'ing about his rwhp, or about his mods

My best friend has an 01 bullit with a procharger at about 8psi,he also has bbk longtubes and an offroad x-pipe.He makes just under 400hp at the wheel.Yah,about the 580hp on stock guts.I've seen damn close with an air to water intercooled kenne belle at only 14psi on stock guts.But Turo is right about the heads they are non PI heads and are very restictive I'd expect 350-380rwhp on a good tune.Or maybe your not getting the entire truth?Could be all forged!

I've known this guy for a while, and while I was in high school(4 yrs ago) this guy was like a legend or something. He had a 95 cobra that had a supercharger and twisted witch heads on it, I think thats what they were called and some other mods. Anyway, that car was fast, I remember he raced a viper, don't know what year, but he did good. He has always had fast cars and is a real nice guy. I just thought when he told me this info on Fri afternoon that either he is leaving out a big piece of the pie or is BSing me on the hp #'s. I believe him on his track times though.

it dont take 580rwhp to run 11.8's i do that on nittos with 420rwhp

Twisted Wedge.

It's would take a fully built motor at about 20psi to make that kind of power. He's full of ****. He probably makes 400rwhp.

thats funny cuz their is a guy here in michigan who clames the same it was a black cobra i think same year not sure, said he had over 500rwhp ran 11s on drags and was running 15psi without an intercooler. i call bs.

technical

I think I like "Twisted Witch" better.

Dave@Ramchargers

No way a 98 car makes that kind of power on a stock motor. Usually the 96-98 cars with a vortech only run about what a good running ls1 car will run.

The guy is either a liar or completely clueless.

slow

maybe with a set of fully ported COBRA heads (32 valve conversion) , forged bottom end, and some spray, will he make those kind of numbers

It would need cams/heads/built bottom end, 20psi, etc. to make those numbers.

It could still run a high 11 second pass with the blower on a stock motor though. Don't get the dyno numbers and track times confused.

That guy is so full of his own **** it is hurting his convo skills. The stock bottom end and rotating assymbly will take a max of 400 hp, but that is not without cost. The wear on that boosted engine will litereally make those rods twist leaving him with nothing more than a mangled block and blown motor. He is running way too much compression to be running 15 psi, and I guarantee you the first time he does really hit the ammount of boost his engine will show him the meaning of pain and expense. As for the heads and intake on that car, they will hardly support that kind of flow from an S-trim blower due to the fact that they don't flow as well, and cavitate horribly with that ammount of preassure put on them. THe pre PI heads, intake, and ignition system were never designed to take that kind of abuse, so rest assured that he is talking out of both asses...his mouth and his...well ***.
Unit 213 knows exactly what I am talking about when I say twisted connecting rods, as alot of guys over at SVTP post pics of what their GT motors did after they boosted them. That car is slow, it may sound real mean, but it is still a mid to low 13 second car if he is a good driver, which I doubt very seriously that he is. How old is this guy 17 or 18?

LS1SS4ever

No way 580rwhp to run 11.8's!!!it should be lower than this #

unit213

400rwhp can hit 11.8's though which is probably what he's making...maybe less.

T-maxx

You are kidding..right? Not about the numbers but the " conversion ".

This guy is older than me and I'm 22. He's in his mid twentys probably. I am fixing to call him up and find out if he got his car back together over the weekend. He had said he tried the shortys to make getting to the transmission easier but it didn't help. and that he lost 50rwhp in the process. So he said he was putting the longtubes back on. By the way, he doesn't do his own work, he pays someone to do it. He has done all his dyno runs at TEA in Bowling Green KY, a little over a hour a way. If someone on here has the hookup with them they should call them up and get the real scoop on this car. His name is Nathan Rager.

He's either full of ****, sandbagging, or believing the people that are selling parts to him with false promises!!! The '98 GTs were dogs, I rode in one with an ATI Procharger and some other mods and it felt weaker than my H/C/I 5.0 GT. Even if it was a DOHC Cobra with an S-trim and full exhaust I'd be surprised if it put down more than 450 rwhp...

TEA doesn't do any of the work, that is just where he goes to dyno it.

I know, I wouldn't suspect TEA of doing something that shady... I had good luck with them when they flowtested the heads on my old Mustang.
