88iroc-z 5sp vs 94 mustang gt 5.0 5sp

Me and my friend argue all the time about who's car is faster yada-yada-yada.
But with his mods which aren't much just a flowmaster 2 1/2in exhaust and my iroc-z's fiberglass ram air hood, flowmaster 40's, and the fact that I'll probably have my holley throttle body back in by then.
I just gotta know, because the driver is the bigest variable in a race but statisically the odds seem in my favor. No??

Please leave some comments and I'd like to see some kind of discusion going.

Re: 88iroc-z 5sp vs 94 mustang gt 5.0 5sp

its purely a drivers race. both cars weigh roughly the same and have the same power. both are manuals. both have catbacks. your ram air hood wont do anything unless you have the airbox setup to go with it. a bigger throttle body will net you no improvement

its gonna come down to who can launch and shift better

Re: 88iroc-z 5sp vs 94 mustang gt 5.0 5sp

Im pretty sure the 88 IROC had 195 HP stock and the 94 GT has around 215. Not much differance. I think if you are both equal drivers he will probably barely edge you out. But like tpivette said, it more than likely be a drivers race.

Re: 88iroc-z 5sp vs 94 mustang gt 5.0 5sp

Good to know I kind of take both sides of the sword so I expected it to be that way, but to answer tpivette my ram air hood is fully functional the air-box sits behind almost right above the radiator. I haven't gone so far as to go into specs and what not just common facts about both, but I figure if confident with my driving it should be cake but always expect the unexpected I guess.

Re: 88iroc-z 5sp vs 94 mustang gt 5.0 5sp

the 88 IROC with the manual trans was rated at 220hp i believe. the autos got the 190hp version. i think the 94/95 Stangs were rated at 225, but im not 100% sure on that

i cant tell you exactly how much the functional ram air will add... maybe 5 - 10 hp. its still going to be a drivers race either way

Re: 88iroc-z 5sp vs 94 mustang gt 5.0 5sp

Your right....I forgot the M5 got the higher HP. I am pretty sure 94-96 302 stangs had 215 hp but I may be confusing them with 4.6's. I have never been able to find any consistant data on them.

Re: 88iroc-z 5sp vs 94 mustang gt 5.0 5sp

ya, idk if hes going to go through with it now lol. I'm going to see if he will soon but he's said anytime and every time I ask he gives me an excuse but, I'm in no rush hes got going on right now so I'll cut the poor guy some slack he came by when I was working on it and kinda went on and on about his car and every time since then I rag on him about the race.

Re: 88iroc-z 5sp vs 94 mustang gt 5.0 5sp

If you know how to shift right like you seem confident in doing, you beat him, remember, you have low end torque, so if you can get through the first couple of shifts you should clearly beat him. yea 88 iroc got about 220-225 hp with the 5 speed,mustang has same power about.

Re: 88iroc-z 5sp vs 94 mustang gt 5.0 5sp

The Mustang's 5.0 got downgraded from 225HP to 215HP in 1993 supposedly due to a different rating system (I believe that is was downgraded to not make the upcoming 4.6 look bad...). However, it is still the same 5.0 from 1987 with just an intake bend, hypereutectic pistons and different accessory drive. The SN95 was a couple hundred pounds heavier than a comparable Fox-body. I think it will be a great race!

Re: 88iroc-z 5sp vs 94 mustang gt 5.0 5sp

Ya, if only he would come around. I was considering going to my 1/4 strip Infeneon raceway and see if I'd get lucky with a 94-97gt kill. Like you say it's the racer and I'm as stubburn and confident as it gets. I usually know when I'm going to loose although a few sleepers have gotten me before. I'm hating this weather sigh rain, rain, and more rain

as much as i hate mustangs it should win, the 305 is a good motor but it never had enough to beat up on mustangs, the L98 was the pony killer

I think you will have a much easier time with a 1996-98 (pre-PI) 4.6 Mustang GT. They were total slugs...

Re: 88iroc-z 5sp vs 94 mustang gt 5.0 5sp

the only reason why i say you should win, is because realistically we always compare these races against the mustang against 3rd gen automatic. you have the 5 speed in your car though. trust me, the manuals in third gens makes a huge difference on these cars, and they are stupid fast if you know how jam through each gear like a bat outta hell. the 305 makes up for having a stick mated to it, the autos are just slow and boring.

I always felt the same, why have something like a thirdgen and not go stick. Unless you put alot under the hood but still. Still wish chevy made the 350 CID 5.7L with a stick but they never disburse I can't argue I wasn't born then lol only 19. A buddy of mine is making the effert to make his 93 notch mustang lx haul *** only problem is he's got an auto running really high gears like 4.10(which I though where too high I went with 3.73's) and he just got his nos kit installed.

Oh sweet you live in the Bay Area? Where abouts? I live in Windsor, north of Santa Rosa. Yeah these cars don't do well in the rain. When I first bought my car I almost lost a race to a 4.3l V6 GMC Sonoma due to no traction almost through first. Well, I also had a plug bridged with carbon and it need a full tune-up so lol. Mine only has around 200 anyway .

Live between Newark and Fremont it's so close if I had to guess I'd say Fremont. Ya, this rain is just a huge mood kill. I just want it to pass weather forecast says 70's next week but ehh. I want some 80's, I always told myself the worst thing I did to my iroc when I bought was take it from Arizona, there the laws are alot better then Cali not to mention the weather lol

Be glad you're not in the northeast. We got 18 inches of snow two days ago.

trust me the gt 5.0s arent the ****, my buddy has an 95 gt 5.0 with shift kit, built tranny, completely stock other than that, and i beat it o my stock L98 with a shitty 700r4 in it. dont worry about it, and if your buddy is adding all that crap, tell him to man up, and stock being a p***y and race motor to motor. only way to go.

You guys are lucky...almost all the mustangs here are BEASTS and I'm no where near ready enough to take them on with my 'bird. Big mustang following around here. Although, I've noticed more and more 3rd gens as of late

I say you've got him!

I love Arizona. I love the roads heading there and back. Forgive me, I forgot the names/numbers, but those old desert hwys where every certain amount of miles you see a white cross on the side of the road. They've always been family trips, but I've always wanted to take my car out there and see how fast I can get her up to.....and also try not to earn myself a white cross lol. Arizona is great though, we almost moved to the Prescott/Chino Valley area. When in bloom, the desert is beautiful. I don't think Arizona has any smog tests, right? That would be my main thing .

ya Arizona was amazing, it vast nothingness but desert and track is perfect for a thirdgen owner. I can't tell you how much dust i got out of the engine compartment when I cleaned it tho lol but it wasn't bad the previous owner only had 49k miles on it. I think its really low smog laws I still think some are there but they treat it like Mexico treats underage drinking no one really cares lol. An added bonus is the tint law isn't enforced in Cali the officers are scared someone with tint will shoot them through their own window so they only allow the back window tinted to w/e or it have to come with the tint stock. In Arizona its a matter of making your car 15-25 degrees cooler then outside temp. Still I love the bay, more people, car shows(like goodguys in pleasington on march27-28), and things to do. I just hate the weather right now lol.

Ya true don't get me wrong. I live in Fremont,CA and there are so many mustangs it's gotten to the point where you see more of them then Volkswagen Bugs lol almost made a game out of it but there isn't a silly name to call it when I hit my friend in passenger lol. Seriously tho, I see some thirdgens but they are more common in union city/Hayward here in town theirs like 3 that I know I know 1 person with a GTA tho. I live down the street from a 1970 mustang mach1 and its completely restored the guy says my car is amazing while I'm speechless of his mustang lol.

You'll beat him and when you do, tell him "shoulda bought a fox" or better yet "shoulda bought a camaro".

Let us know how it goes! I'd love to put roller 305 in mine, so at minimum I have closer to the same horsepower yours puts down. Yeah, yeah....go 350. In California that's easier said than done.

true that, with all the crap we face in california its not fair anymore lol. We practically have to be bone stock to pass emissions and the cops are getting more annoying then usual. I had one pull me over trying to say I didnt signal at a turn(which I did, I won't lie sometimes I don't always signal but I saw his *** in my rear view mirror and I signaled) then he wanted to look under my hood and I told him no. Lol, he couldn't do anything he had no right to look under my hood I basically said "what seems to be the problem officer" he told me the whole signal crap and then I said "what does my signaling have to do with under my hood?" so he gave me the ticket and got a few people who saw me get pulled over give me their info, I'll see his *** in court. haha

The tpi 305, without the peanut cam, was rated at 215-225 hp, 302 gt's have 225, my friend owns one, and the gt has 10 more tq. I may be wrong, as i dont know much about 305 engines, I have heard that the 302 in mustang gt's walk all over 305's,I think its because 302's are high revving engines, and 305's have a short power band, but I hate saying that because I want a 305 tpi insanely bad.

A stock 302 will beat a stock 305 TPI, L98 has NO problem beating a stock 302 no matter whats behind it....
