1990 IROC that kills 5.0's,4.6's,LT1's, and L98's
I'm getting sick and tired of 5.0 mustangs having blowers just to hang with a 350 chevy. At the strip this weekend My car ran 14.5@ 95mph, while that doesn't seem too fast, for 5500 feet it was fast enough to beat almost every non supercharged car there.I only lost to two supercharged cobras with slicks. I hate supercharged 5.0's I would only loose by two or three car length's.

hmmm.....
What is your best corrected e.t.????
Those must have been some weak-sauce Stangs for you to hang like you say.
A modded supercharged 5.0 should be DEEP in the 12's or in the high 11's. Depends on traction two, and the type of blower.
If you lost to a C5 by a fender that means you are in the low 13's with a possibility of 12's.
Supercharged stangs running 13's????

Just put someone who can drive behind some of those cars, and you would have lost quite a few more of those races. I guess that your car is running mid high 13s. And s/c 5.0's pulling 2-3 car on you is more than running with you, that is beating you by quite a bit in the 1/4. Bolt-on 5.0's would probally be hanging with, h/c guys would be past you.

Just wondering where in New Mexico you are. I was in Roswell last year at about 4000 feet and was running 14.1's at 9X, don't remember, I only ran a few times. Sounds like you had a fun two nights though, good kills. What mods do you have?
Whoa, I just read though your list, "96 Z28 w/LT4 heads and cam," that surprises me, about the same mods I've got. Must be some terrible drivers up there. Not putting down your car at all, just would have thought that car would run faster than that. Good kill nonetheless.

Yeh man ur right those drivers must be terrible. The 96 Z-28 should run a low 14. My buddies 95 Trans am 350 auto stock ran a 14.4 and he could do better. 5.0 Stangs 5speed should run high 14's than with exhaust and intake around mid. They should be givin u some trouble. good kills anyway makes u sound better

Just curious...would a supercharged or turboed car get the same altitude correction factor? I would think not since they are not nearly as affected by high altitude compared to NA cars. If they got the same factor, it would be incorrect because the non NA car would not run what the factor says at sea level.

all the free mods in the world couldnt put that car into the 12's.... unless he has a set of ported LT4 heads and LT4 hot cam and took off about 300lbs. Also, TC, and rear gears...
Maybe with an LS1... but LT1 with just that... thats fantastic!

Yea, at 5500ft, that is about 1 second slower than sea level. So read his initial post and subtract a second from all the "casualty's" times. Good kills man. At least we know you can drive down there in "stunt" mexico

I had a HOT cammed WS6 and the best mph I ever turned in that car was 111.7. Best ET was 12.4@111.
Not going to happen with those mods, more to it than that.

I have race numerous close to stock LT1's on and off the track. They are not that much faster IMHO than a 89-92 L98
my girlfriends LT1 94' Formula with over 115k on the clock has run a best of 13.6 at 101mph with only drag radials and cold air. this is in 80* weather and with her driving! highly doubtful an fbody 350TPI can match those #s with those mods
we just installed a SLP "loudmouth" catback, and with some cooler weather were looking for some 13.4s at 102/103mph. not to bad for just 2 boltons and tires!

uhh I know many a blown 5.0 running 10s... that's just a BIT faster than your regular old BUILT 350. I hate fords as much as the next camaro guy, but your blind hatred is lame. a 302 isn't a dinky dick motor, it's got a great deal of potential and the stockers were just a nudge behind a 350 TPI and an LT1. thr 4.6 was the *** motor.
Not to flame... but another *** dam mustang chit chat?
Jesus... back to stangnet.com for you guys!! I guess they dont have anything cool going on there?
Yes 5.0's are easy to mod and parts are cheap...
but a 350 can be as cheap if not cheaper to do... just present EFI applications seem to cost to *** dam much. By the time you get a decent intake with all the parts, and a engine that can haul.... you can just get a LS1 crate motor... or LS6. mmmm LS6....
