It is more than possible for a 2v running that boost to make that power. My best friend had a vortech that peaked @ 11psi, o/r x pipe, flowmaster muffs, 3.73 gears, and all the other bullshit that is needed when boosting a car on his 04 GT 5speed. With a tune his car put down 403 rwhp and 38x rwtq. This was with the engine otherwise untouched on the stock bottom end, he ran this setup for 15k miles before he sold the car with not one problem, it's all in the tune. This guy the OP is talking about might be lying, but they can reach that power level. Oh, and my friend would eat modded LS1's all day long in his car. Funniest kill was a 01 WS6 that had the license plate GTKILLR. So if he is telling the truth, watch out. People on this site always seem surprised that a blown 2 valve reaches that power, cuz around here they are everywhere. 8 out of 10 charged 2 valve(pi cars) I see make no less than 380 rwhp. Of course, we have some great Ford shops around here, that no there **** and how to tune., when it comes to Mustangs (Modular Powerhouse,Higgins, couple of others)

Oh and it's really no comparison of a 96-98 2 valve and 99-04 2 valve. They are totally different, as others have mentioned, so dont go off what you know of blown non-pi GT's, they are teh suck, and make no power.

I must depend on the car and the tune. My friend had a 2000 Saleen vert with a Vortech blower. On 13 psi and race gas it made 403 rwhp. He put a larger pulley on it and tuned it for pump gas. Never redynoed it, but we raced about 10 times from a roll and everytime I would pull him about 1 to 1-1/2 lengths from 60-120. At the time my Z28 made 344 rwhp. He had his top down and I had my t-tops off. I had a 190lbs passenger and he had a 110lbs passenger.

I don't know where you come in with this "GT will beat you" crap, because no GT with 10psi is going to touch my car. Mine lays down 520 on a 150shot so I don't think i'll ever see the back end of a supercharged GT on 10psi. I never said anything about beating one anyway, or getting beat by one. Again, upper 300's on 8psi, I would love to see some proof but I doubt you have any.

400rw is a bit much for a stock 2V and if he does put down that power the block wont last long. a buddy blew his GT block with a blower and now has a 03 cobra bottom end

First off....Intakes come with blowers...so that's not saying much. It is pretty much a given. Secondly....how do we know he only has a catback? Nobody has talked to this guy at all. So this is all hear-say ****.

Can a 2v reach 400RWHP blown..sure they can. Does this one?...I doubt it. (if he only has the blower and catback). IMO, he is ~380RWHP....but that's just me.

bottom line....we can speculate all day, until someone talks to him, and looks at his dyno run.

And I am glad to see this post......it helps weed out the LSx folks that really know mustangs, and those that have no clue.

I think the car with the drag radials will win.

He blew the block? Or blew a rod out the side of the block? Cuz a GT block is ALMOST as strong as an '03-04 Cobra block. It's the internals that are the weak link, and with PROPER tuning, 400-415rwhp is the limit I would go on pump gas, for a daily driver. I've seen plenty of stock-internal GTs with 390-410rwhp, as daily drivers.

i dont know what he blew but i wasnt pretty. when i see him i'll ask him

"stock"

sorry buddy but 97gt's were non pi and dogs trust me i own a 96gt.The 99 with a pro charger at 10psi with a cat back and a good pump gas tune will make 415-430 easily.

"stock"

im not on here to be a smartass or anything i own a mustang and i joined because i want a ls1.As for your comment about upper 300's on 8psi i can show you several got one friend with a 03gt vortech 8psi no aftercooler making 362, another with a 96 gt procharged 10psi making 427 and shane ONEMEANZ knows both of them.There are pics of these cars on here under local mustang club i think is the name of the thread.
