TPI and top end don't go in the same sentence together, lol. My old LB9 even with a mid sized comp cam in it stopped making power at like 4900 RPM's.

It is a relief reading though some of these comments... nice to see many of you 3rd gen guys know your stuff, and seem very honest and non-bias towards Mustangs. Good stuff fellas! I'm impressed with the 3rd gen knowledge... Great stuff from members like Stangski09, whitedevilTA, and fly89gta

Great example from Stangski09 with the 14.5 - 15 second runs. The best (recorded time) any 3rd gen (non Firehawk or TTA) could do was a 14.4 and that was a 5.7 liter 1990 1LE model, with the 5.0 version manual pulling a 14.6 but I've seen some stock L98 1990-92 F-bodies run best of 14.5 and my cars (1990 G92 5-speed) has run a best of 14.7, and most new edge SN95 Mustangs were low-mid 14 second runners that usually dyno'd around 235hp @ the rear wheels. They are very competetive and even with an LT1 powered F-body. But anyone that has owned an L98 F-body knows that with a header-exhaust change and decent breathing on the intake side, they will run with an LT1.

Not sure about the convertibles times though, as stated, they are heavier... and the automatics are slower, I actually would have to give this win to the 5.7 liter 3rd gen.

I'm perhaps one of the least biased, check the sig.

I am getting tired of driving the Mustang, and seeing the IROC sit though. I really wanted a second daily driver to save a little bit of gas, but I think I'm finally going to stroke the IROC out to a 383 this year. I've been planning and planning, but I always end up wanting something else.

a 4th gen mustang gt, vs a 350 tpi 3rd gen should be a close race, I have heard the 4.6s aren't much to be scared of, personally I think they are pretty quick, the 350 tpi has it on torque, but the 4.6 has it on top end.

As far as shifting into 4th/OD at WOT, as far as 1/4 mile is concerned, unless you're running past 120 at the end it won't matter, with 3.42s anyways, highway gears you would have to run even faster, but I know that I checked once and my car is pretty much limited by the trans to 120, which sucks because it would probably do 140+ if it had 4th.

Mine will handle it's own against most TPI cars out there, and probably some bolt on LT1 cars. Then again, it's a 5 speed car with 3.73s, CAI, Flowmaster catback, custom tunes. I should be able to get a little more power out of it soon. I have a cracked catalytic converter that I suspect is clogged. So I'm ordering up a couple sections of straight pipe. The non catalytic converters from siliconeintakes. Already ordered some more custom tunes from Bama for an offroad mid pipe. My catted X pipe with a cracked cat isn't too much of a bragging point for performance. LOL.

I ran into a Chevy Cobalt SS that stayed pretty close to me until 100. I passed him at about 60 on the highway, so I suppose he decided he wanted a little race, and got the jump on me while I was downshifting to 3rd. It was an ego killer to finally run into a quick 4 cylinder car, even though I put a few lengths on him and ran the Mustang out in 4th, to about 125.

I believe the supercharged Cobalt SS was at 230 HP, and the turbo Cobalt SS is 260, but I have no clue if it was stock.

So, they aren't something to be scared of, but they are fairly quick, and will handle their own against a lot of cars out there. I know that my GT will feel slow as ***** compared to the IROC if I ever get it built the way I want. Aluminum 185CC Edelbrock Performer RPM heads, 10.5:1 forged 383 stroker from Eagle, full manual valve body for my 700R4, 3,200-3,500 stall, and probably a Comp XR300 retrofit roller. Cam seems like a bit much, but it should be good for that type of compression and stall. The only problem would be that I couldn't launch it with that setup, with my stock 10 bolt. I'd be able to leave the line at close to 3 grand just off the foot brake, and it'd probably instantly wind up to almost 4 grand with that combination of cam and the high stall, and just shred the 10 bolt.

1999-04 (new edge SN95) 4.6 liter 2V Mustangs are very respectable. A decent optioned 2002 GT was ran and recorded by Muscle Mustang & Fast Ford Magazine in one of my 2002 issues, and ran in the 13 second range, from the factory, with a seasoned Mustang driver, at Englishtown, NJ.

These 99-04 Modular Mustangs rev forever, and wake up with basic and common bolt-on mods. Hell, just Cold Air Kit and Exhaust mods will put these cars in the 250-260 rear wheel HP range on the dyno, coupled with gears (modular Mustangs come alive with 4.30 gears) and the DOHC 4V version Cobras are just super nasty with bolt-on mods and gears. Awesome cars that should be respected. I've always wanted to get one of these cars to play with.

I got alot of respect for those later Foxbody Mustang's, the 88 to 92's. They're lighter, agile, aerodynamic and fast when souped up with some bolt-on's, exhaust and CAI. I don't ever underestimate one of those if I go up against one. They're basically the only real Mustang that I would ever want to own and maybe a 03 Cobra.

nedaCFilms

2003-04 SVT Cobra Mustangs are legendary already... as are the 2005-06 GTO. I'd love to have one of each...LOL!!! But if I could have any car, it would be a dark green 1992 SLP Firehawk. Fat chance with only 25 produced...LOL!!! I guess I could always clone a '92 Formula, but it would be hard just trying to find one of those T-Ram intakes.

There's a guy on LS1tech with a turbo cobalt 4 door. They're a NIGHT and day difference from the old crap supercharged version. With only a tune on his he has run with some very quick cars and beaten a lot of the ones he races. I want to say he trapped around 107 mph in the 1/4 which is crazy for a tune only econo car!

I owned an 08 stang for a while. Those 3 valve engines aren't as great as the new 5.0 but they still respond well to bolt ons and the car was one of the nicer cars I've owned in terms of quality and performance. I don't care much for fox mustangs because they are too "escort" looking. The F-bodies stayed true to thier long nose RWD styling while ford started making the mustang look like a shortened economy car when the fox body came out. I still like some of the ones I see, but the style isn't my thing for the most part.

Amen, same here! Bruce from Hawks third gen owns/owned one and the car is gorgeous! Problem with those is you'll never get a loan through a bank for a 92 formula for around $30k which means thats a LOT of saving to do, lol.

That time on the 88 Iroc doesn"t look right. Stock 1990 Iroc 350 tpi,auto ran 0-60 in 5.8 1/4 mile in 14.4

SC 4.6 GT would kill the TPI car sorry.

Non sc you may still have your hands full.
Used to run against a freinds 4.6 GT cant remember all what he had done to it. Gears bolt ons etc. Beat him ea time in a stock 89 TPI Vette with catback it was very close though. Get him out of the hole every time, couldnt run me down in time but the gap was def. getting small towards the end. Dead even start think he would have nosed me out

This was about 5 yrs ago at LACR not on the street

I will say his mph bested mine and it wasnt far apart. From a roll thing the mustang would walk away easy.

nedaCFilms

I think they were comparing the TPI to a 4.6 liter cougar or something... but you are so right, no way a stock late 80's early 90's TPI can handle the 1999-04 Mustang GT with 4.6 liter... they dyno'd around 30 more HP at the wheels and ran low 14 second times, and high 13 second times with a skilled driver. Best any TPI car could do was a mid 14 second time.

I have had both. I think I would give the edge to the mustang with 260 hp vs the l98's 230. It would be a drivers race but the stang would have a slight edge.

That's why I strive to be the absolute best driver I can.

The best pass from an Lb9 5spd was a 14.7 modded with boltons full exhaust etc. 13.9back when they were newer.

You'll should get to the track more often.

I have seen a tuned stock L03/5spd car go low 15s with a 3.08 gear.
