Default Turbo 5.0 coupe vs. STS LS1 T/A

actually it was pretty even. I don't get into to many races anymore much less against another turbo car. Had a chance to pull over and talk with the guys in the T/A. Good looking car and a couple of great guys. I'll see you guys at the track sometime....

cool, but w/ your wheel horse power I don't see how it was even. sts systems on stock boost put an fbody into the 420+ rwhp range. that wouldn't be a fare fight. Hey, but anything can happen, maybe he sucked ***** at driving his car. at least you had a good run.

rwhp only matters when your dyno racing, vehicle weight plays a big roll when you're actually racing. My coupe is 3200 w/me and i'll bet they were close to 4000... my car and yours seem to have dynoed very similarly, what kind of times do you run?

Its true that weight has a huge factor in street racing but judging by your 1/4 mile ET he should have beat you even if he was closer to 4000 he would have been able to hit 12's IMO.

Nice run though

umm, i don't even know how to respond to that. I didn't come in here to start a fight. Just making a post.

we ran from a 45mph roll, traction at that point was a non issue. And considering on my 13.02 run I had a lousy 2.23 60' and I had to feather the thottle most of the way thru 2nd to prevent wheel spin 12's are easily obtainable... And the car usually cuts 1.99-2.0 60' times.

anyone else want to speculate on why the T/A should have beaten me? Maybe his lane was longer than mine on that particular stretch of road which means he would have had to drive a longer distance to catch me.

Or maybe he should have won on the basis that this is an LS1 website

well from a roll the difference in weight plays a much smaller role. Considering he should have had an honest 75rwhp over you, better gearing and better aerodyrnamics, it seems kind of off that it would be even. But anything can happen I suppose.

and fwiw, that 350rwhp seems high for a basically stock engine with 4psi.

I run 12.9's-13.0's w/ the weight being 3,7xx lb car + me (240 lbs).
so I out weigh you by ALOT.

and a T/A does not weigh 4000lbs. more like 3650-3750, maybe he a few people in the car??? I could see it that heavy if it was a vert w/ passengers.

dman, I'm not tryin to bust your ***** man, it just sounded a little fishy that's all. I have seen plenty of dyno runs on fbodys w/ the sts system and on stock boost they were all making really good numbers. It is good that your cars weighs alot less, you probably had him by 500 lbs less weight. It was a street race anything can happen and did. Congrats on your kill. w/ your current 60' times, if you get those down your car has mid-high 12's in it. Why not crank up your boost some???

I agree. Trapping 113 tells me your car is leaving a lot on the table. Get some slicks and you should see at least low 12's. Nevertheless, good kill.

wait a minute here!!!!! I NEVER said I beat him. He was behind me when we hit it and he pretty much stayed there. Not once in this post did I ever say I won. I would only base a win or lose on if both cars were side by side and left at the same time, which we weren't. I'm in no way talking down about the T/A, I just figured I would post this so maybe the guys (yes 2 guys as I mentioned before) would see this and could keep in touch. I would bet money his car was pushing close to 4000 lb's as both guys were an easy 200 lb's each. My buddies 00' SS camaro weighs 3550 without him and he's done some things to lighten his car so thats why I estimated his weight at 4000 lb's.

car ramrod - I really don't know he had a 75rwhp advantage on me (neither do you) . when I dynoed my car it was 110* in the dyno room and the car was hot from the drive over. Not to mention it was at 4psi and now it's at 5psi (which in my past experience is worth about 20-25rwhp) which would put me closer to 375rwhp.(The car dynoed 265rwhp before the turbo install) Now throw in the fact that he had just been in boost catching up to me so we could race which most likely put some added heat into the equation I see no reason the cars couldn't have been even at that time.

01mmmz28 - what was your MPH ? ET is effected more by 60' times as i've gone 12.86 @ 104 on slicks before the turbo. MPH is the deciding factor in a street race from a roll.

superstocker - I agree. sticky tires will put me right in the 11's and also improve my trap speed. just for some added info my 1/8th mile numbers were:
8.65 @ 88.27 which means despite the car laying over after 5000rpm it still picked up 25mph from 1/8th to 1/4. My last combo in this car picked up 6mph in the 1/8th going from non-hooking radials to ET streets.

i had the feeling this would happen if I posted here. Fishing was not my intent, Willie and Jose said they were on this board so i figured i would post here and say hey....

dont worry man, were just posting up questions as to why it didnt make much sense. Now that you said your prob making close to 375 rwhp with 500 lb weight advantage, that does make sense.

Nice run, you had some fun, no one got a ticket, and you had a good talk afterward without bashing each other. I would say it was win..win for all involved.

alls I want to say is to many people on this board get caught up in dyno numbers and what it should have or should do.
go to your local track walk around look at the cars and see what they run.
that mustang has 11s writen all over it.
oh and good race!

bro, nobody said anything outta line. You take this stuff way so serious and personal. If you held him off and he didn't pull ya, I'd say you got him.

asking about my times: best ever was 12.910@ 107 mph 1.9 60'
best current : 13.00@ 111mph (spinning )
w/ a 2.0 60'
both were on street tires.
take it easy man...........

My car stock motord with 100 shot went 7.8@88.56 with a 1.79 60 @ the 1/8th on my 12.3 pass. I think with tires that car should easily be in the 11s.

01mmmz28 - hey i'm cool. I was just getting the feeling I was being called a liar. boosted99 is right, everybody hears dyno numbers and thinks that it's an error free conversion over to track numbers. So many variables are at play when it comes to a street race especially when it's from a roll and one car is behind the other. I really don't consider it a win unless I start out next to someone and end up in front of them.

I guess we've beat this dead horse enough, so lets move on.

Don't worry about these guys, most of them overlook the obvious when they hear that a Mustang ran even with an LS1.

Nice run. Now go buy a real block, some good internals, and crank up the boost.
