I'd be confident in my lightly modded LG4 beating that particular mustang, given he's stock. I could routinely pull the slightly heavier 95 5.0 Cougar my buddy had, and that was with my low 15 second Grand Am, we never got to make a run against the Camaro, but I can tell that the Camaro smokes the Grand Am pretty easily. I would think a stock L98 would have the win pretty easy win, with a cam it would just be even less of a race.

I looked at the car, its in between from what i saw a Cold air intake, and gutted cats with a stock exhaust

Maybe a throttlebody but i didnt see anything below that unstock


... Heres what he just sent me "just research it! 285 hp get over it cry baby."

Hahaha he is going down!!! I just got my injectors in today.. SHELL fire up by tomorow!

btw 25thmustang, is that your stang in your avatar??

Thats beautiful... i normally dont like them to much, Besides my uncles 90 notch with a 302 bolt on with 7 psi makes about 600 to the rear wheel :O

It takes more than 7psi to put out 600 hp at the flywheel let alone at the wheels with just a "bolt-on" 302

Re: 87 l98 VS 95 5.0

before he had it tuned it made 523 rwhp, and 540 ft pnds of torque

he has a stock block with forged pistons, trickflow heads, 42 pnd injectors, and a cobra r intake.


and he has turbo headers, y piped to the intercooled turbo and a 3 and a half inch downpipe dumped under the floor.

Hes in the process of tuning it now, and just yesterdathey had it running lean and picked up about 50 horse, and they still have a ways to go

Re: 87 l98 VS 95 5.0

Yes thats my car, and thanks I just got it back on the road and back on the race track.

The motor in your uncles car sounds stout, but there was no Cobra R specific intake, so it might just be a stocker Cobra. Other than that I assume its a simple HCI car with a small turbo on it. The power he made seems alright, but 7psi seems low to make that. I figure 8-10 would be a minimum unless there is work he isn't telling you about. All in all still a fast car I'm sure.

Re: 87 l98 VS 95 5.0

yeah, its a quick car, and still has alot more in tuning

I just got my car fired up today, Kinda rough :/ I need to adjust the valves because the vacuum gauge was flucuating between a solid 19, then jumping 15-10-15-10

Re: 87 l98 VS 95 5.0

7 psi, of how much air dudes? and at what temperature? compression ratio? lotta variables left on the table to write that off. also rpm, if it spins to 6500-7000 that's a big difference.

Re: 87 l98 VS 95 5.0

it's a stretch but not as huge as they make it out to be. hp is dependent on rpm, and people that base power in a turbo car on psi alone haven't spent much time in the turbo scene. i haven't either but i've seen plenty of "noobs" on 240 sx forums asking how much boost it takes to make x amount of power and they get the talk that psi isn't even close to the only number that affects it. how large is the turbo, whats its efficiencies, a/r ratio,lots of stuff. if you have a turbo the size of say my fathers in his 5.7 liter turbo diesel, you can push 500 hp stock. why? rediculous torque, my t/a fears that damned dodge...

I agree but only 7psi?do you really think that you could put out over 600 whp with that amount of boost with only 302ci and a couple of bolt ons?i say prove it!!

I'm not calling you a liar at all if you have seen the dyno sheet then its all good i just think theres more to the car then what he has told you because those are pretty big #'s for what your telling us,thats all

It doesnt matter if you have the best turbo money can but if the entire package doesnt work it wont make power!Im not trying to say that a 302 cant make 600whp im just saying it cant do it with only 7psi,sorry for any mix ups

Re: 87 l98 VS 95 5.0

A 302 could do it with 7psi, it's just a matter of what HCI set up, and 7psi from what, like stated before. A solid HCI car done right, with a larger turbo making 7psi, could put down that power.

Make sure you get your eprom adjusted for the larger injectors or you'll run far too rich and loss power. If you spent a little more time on the spark advance, you could gain even more. A properly "hands-on" tuned eprom could gain you up to 4/10ths (half for the fuel and half for the spark).

Re: 87 l98 VS 95 5.0

If you just put injectors on, and nothing else, you're not really gaining anything. As far as the post goes though, I think you'll have the mustang in a race.

the 94-95 5.0's werent special but im sure if you spun out of the whole you would have a hard time catching up on the top end TPI is good for out the whole and low rpms that 5.0 im sure has more 5000+ power and torque then your l98 so im sure you can top end you
