Buddy of mine picked up a 94 Mustang GT with the 5.0, 5 speed. Put a 70mm throttle body on it, bigger injectors, fuel pump, digital 6 msd, and topped it with an On3 performance turbo kit with a 70mm turbo. Pushing 11psi the dyno he was on says he is pushing 496whp and 567torque. Im not new to stangs but this sounds WAY to high for this application. Any opinions on this?
Sounds a little high, I'd be a little surprised that his turbo put down that much torque for sure...but I'm not the expert on Mustangs, there are a few on here that put down good numbers.
Fwiw though, that On3 kit is sort of shoddy....you can put it together for about half of what the guy charges....and he sells the Chinese turbos.
Bone stock internal 302? Or is it bigger? Got a nice top end setup? It seems high for a stock bottom end 5 liter, the torque especially. What kinda Dyno was it on? I know you mentioned some parts, but w/o having even a cam swap, not so sure.
The hot side looks decent, it's hard to beat the price especially for the 4.6 kits.Quote:

that motor stock put out about 190 rwhp i call bullshit on 11 psi
Did your buddy show you the dyno sheet?Quote:

Im actually going to agree.Quote:

Also lets not forget thats a stock block lol Ive split a valley at 450 to the tire, but that was spray totaly different situation. Put back the 15% lose and thats a 570/652 at the crank...lol Im gonna call BS as well.... But bang for the buck thats a nice kit.
Maybe some of the guys on this forum that have ACTUALLY ran a turbo/stock 5.0 long block can shed some light on this.
On3 claims that their kit, on a 5.0 SN95 will make over 400hp to the tire @ 7psi.
So add another 4psi, if the engine doesn't let loose, I think it's possible. The torque number that your friend is claiming seems kind of high to me for some reason, *shrug

I can't imagine something that makes. 225hp at the crank stock making well over 400hp at the wheels, 100% internally stock with something less than 10psi of boost. It probably is possible with alot of boost though.
Just because you can't imagine it, doesn't mean it is not possible.Quote:

That's the thing...THAT claim seems implausible.Quote:

If they're making 400whp, then it's producing more than 7 psi (and prob 15ish if one asked me, on a stock 5.0) . If it's producing 7psi, it's not making 400whp.
You guys need to go back and spend some time on the 8 or so pages of bad feedback about On3 in a number of places. His rep is better on Mustang sites, but turboforums and ls1tech have had some issues.. He's mislabeled and misrepresented parts, kits and numbers on just about every forum he sells stuff on. Sure, for $1500 your not expecting a friggin Heffner turbo setup. The thing is, what he sells can be had cheaper if your really want the same stuff....or you can spend the same $$, and actually end up with a turbo that won't grenade itself or fall in half. He was selling the SAME line of turbo's that were "glued" together from the Chinese manufacturer. Although they don't ship those anymore, he DID sell them and he didn't do SHIT to take care of the customers that ever got screwed. He also won't return phone calls or pm's and complains to mods to have threads deleted if they are "hating" on him.
I'm sure not everything he's sold is junk, and there are plenty of people on the turboforums running ebay variant turbos and home built setups making great power.
Just for a point of reference... I made just over 400 to the wheels at 13psi through an auto. Engine had stock 1983 heads and stock flat tappet cam with an EFI explorer intake.
I agree with the OP that the '94's numbers sound high.
As far as the On3 kits go, I have seen two at oscars. One Sn95 and One Fox. Both owners said that the kit's were trouble free for the most part.
totally off point, but i did tune a 3V 07 mustang with a on3 kit 2 years ago and it appeared to be pretty nice looking, the owner put it on him self and it made 450 at the wheels on 8 or 10 psi. But it seems there is headroom in these kits to make numbers, but limited by the engine they are attached to haha.
Chad the owner got a Ban from the turboforums for the way he treated customers.
I'm not trying to shit on it, I'd just stay away from it if I were in the market. Some people have the kits and it works fine, but many many people got kits with shitty turbos, and a HUGE fluctiation in build quality. I'm pretty sure there is still some threads on YB and the like about him selling kits that never fit from day one to some customers.
If you get your information from Corral, they will tell you he's the god of cheap turbos and that you can haz Cheap Reliable Horsepower....cuz those 3 things come to mind with a budget turbo kit :)
