For those of you that read my post about my friends 2000 Mustang GT with the sean hyland motor vs. My '90, we ran this opening weekend at the track in Albuquerque, NM.
If you remember he has:
Sean Hyland Forged engine
ported&polished heads+cams
Intake,magnaflow exhaust
Racing clutch, 3.73 gears
tuned computer with MAFterburner module
He also got coated Longtubes and off-road X-pipe + 6 speed. We ran a bunch of times and I took him everytime by a lot. His best run of the day was 14.4 @ 96 MPH. I ran a new best of 13.8@103 (12.9 corrected for the 5500ft). It was my first time in the 13's at this elevation!! We were both on street radials with alot of wheel spin (I could only manage a 2.0 60 ft w/wheel spin). He spun too but no as bad as me. I say with slicks I could shave two tenths off the ET- 13.6 (12.7).
Other cars I beat this weekend:
Moded 02 Z28
03 SVT Cobra
01 Corvette
SVT Lightning
2002 Saleen Mustang 281
01 WS6 TA 6sp
Supercharged 5.0 5 sp
Lancer Evolution
AWD modded 95 Turbo Eclipse
HEMI Ram
Turbo Integra VTEC

Looks good but your friends car is junk... He ran a 14.4, which is what a mid 13 in the 1/4 corrected. Thats incredibly bad, he should be mid 13s (mid 12s corrected) at that elevation.

Your cars running pretty good, but his needs a lot of work.

Those are some really nice times for your setup. Do you have any work done to your Vortec heads?Either way those are excellent times. I am building a motor with simalar specs to yours(except for a holley 670,and comp cams XE256H cam) and I am just hoping to hit mid 13's.Nice setup.

yes he needs to do something about his car.

Those times are horrible for that car. Even at that elevation, that just doesn't seem right. My buddy has a 96 GT, 99 PI heads, full exhaust, all the bolt on's, dyno tune, etc... he put down almost 300 and the wheels. He ran a 14.0 @ 104 before the tune. It ran pretty crappy that night as well.

ive never heard of a sean hyland engine is he a good builder. can your friend drive with a 6pd and 373s he should be able to dig and launch like no other. the exhaust chip should have lowerd his ets alot lower seems like he either cant drive or this sean hyland engine is pos cuz he is going slower than a stock gt

25thmustang

First off the 6-speed will drain more power out of his car than any 5-speed...

Second Sean Hyland is an awesome mod motor builder. One of the best out there...

Third, I agree and as stated before, somethings wrong there... he should be easily in the 12s (down at sea level) if not low, low 12s.

All cars are like dog slow at our track compared to what you read in books and on the forum. The best I've seen a 99+ GT do all motor is like 14.8! That was with gears,intake,exhaust, tuning, and drag radials! And the guy was a good driver!! The same guy bolted on a vortech SC and ran 13.8. Stone stock LS1's are clockin 14.6-14.7 with an automatic and 3.23 gears, LT1's auto's are mid to high 15's. Our track has a lot of wind cause it's at the top of a mountain, so maybe that's why everything is so slow. My friend has an Evolution and he can only run 14.1 and that is out of like 20 passes and with a 1.8 60 foot time!!! My friend with the GT can drive his car well but I agree that he should be a little faster, maybe 14.1-14.0(13.1) but no way he'd ever hit 12's at sea level. He has had his car dyno tuned and he put down 260 to the wheels in Albuquerque WITHOUT the Longtubes or off road pipe, he said his corrected RWHP was like 285 at sea level. Stock GT's here dyno at 190 to the wheels. He has his car setup for autocross and his 60 is like 2.3 on streets (245/45/ZR17).

25thmustang

That car with head work and cams should be in the 12s at sea level with traction. My friend Mikes GT ran a 12.17 @ 110 with a stock motor, stock heads, stock cams, Bullit intake, pulleys, timing adjuster, Long Tubes, X-pipe, dumps, 4.30s and suspension. I forget the exact numbers but I think he dynoed 285 or so RWHP. There have been lots of accounts of 12s with not uch more than exhaust, gears and traction.

Im not preaching mustangs just letting you know I think his car should be 12s at a sea level track. From what I have seen.

IROCaholic

Out of all the times I have been to the track I have never seen a 4.6 mustang hit better than high 12's all motor. and thats with good drivers, but maybe there cars were out of tune. My friend had basicially every bolt on you can get and 4.10 gears with drag radials and he was runnin low 13's consistently and he broke a 12.9 once. Now supercharged mustangs is a different story I always see at least 3 or 5 supercharged mustangs runnin in the low 11's. Your friend must be a good driver and his car must be in perfect tune. (those 4.30 gears help aswell).

hydric

I couldn't agree more

jocww

how does a 6 drain more power they dont make more power but they keep you in ur band because its real close so your drop is maybe 800 rpm

demonspeed

Some people might thing that since it has one more gear, it has more rotational mass, which in turn robs some power. You're only in one gear when your driving.

Another good thing about a 6 speed is two over drives. This makes it nicer with lower gears. The tranny can also have lower direct drive gears as a result.

25thmustang

Well check page 7, about half way down you will see a silver GT. That car was the one that went 12.1 @ 110 with bolt ons NA. If you dont believe me I will get you in contact with him...

Also he is a very good driver (you will learn that the people I race heads up with are pretty much ALL good drivers), and the car was tuned on the dyno a lot. I actually know another guy who runs almost the EXACT set-up and went 12.19 @ 110 also. I have vids on my computer of them, so feel free to IM me at MHRA47 and I will gladly send them!

25th im not trying to call you out or anything, looking at most of your post ive seen that you are pretty much always right on the mustang stuff. I was just merely stating that Ive never seen one go that well N/A . I actually think its because most of the mustang guys down here wont put the time and effort into going all motor so they go the easy route and that is supercharging. Ill never accuse someone of lying just becuase I havent personally seen what they say they have seen. There are many different factors that can come into play with peoples ET's. So I really would believe almost anything when it comes to drag racing, its not as predictible as everyone makes it out to be.

Isn't the six speed also a good bit heavier???? The weigth diff in thirdgens with an auto and manual 6 speed are barey different.

25thmustang

Yes it is, and the Mustang 5-speed is lighter by a good 100lbs i believe.

I wasnt doing that to sound mean, I just didnt want you to think I was making it up, so I decided to show you I have proof. Its not my car, I just relay the message. I know plenty of slow Mustangs with SCs running mid to low 13s and such. I cant stand them because I see what Mike did and know they could have too.

IROCaholic

25th I didnt think you sounded mean or anything It just sounded like you were offended and I wanted to make sure I didnt offend you. To get back on topic GASGZLR you didnt answer my question earlier in the post do you have any work done on your vortec heads?

25thmustang

Not that just noone ever believes the times I post and the truth is most that I do, I have video to prove, just putting that out there.

GASGZLR

The only work that is done to them is I got the valve guides cut down, and replaced the stock springs with comp 981's that came with my comp XE268 cam. Then when I changed over to the LT4 HOT cam I left the same springs and that's why I don't use 1.6 rockers cause I am already pushing the limits of the recommended lift with these springs. If you were talking about porting work then NO they are stone stock from the box to my shortblock. I was going to port them but when I pulled a set of valves off to change the springs the ports were fine. There were no sharp edges that I could see in the bowls where you would normally port the head. The exhaust valve also looked backcut compared to a stock one, so I bolted those babies on stock. I got mine from GM performance parts via Jegs.

IROCaholic

Oh thanks for letting me know because I was just trying to get an idea of what my new engine will run. Mine is alot like yours and alot of people have been telling me I will only hit high 13's even with a built suspension and 3.73's.
