Rematch: ls1 Chevelle vs. '11 5.0 GT Cliffs and car specs at bottom.
Was cruising with a buddy to a meet and we followed a noisy group of mopars (srt8 challengers and chargers) out of the lot. They seriously sat in the lot revving like ricers for 2-3 minutes. I was out to humble them some.
They didn't want to play when the time came.
So my friend and I decided to lock up instead when we came to a random light on the bypass. Nice straight 2 mile stretch of nothing.
Light turns and I don't know for sure if he's going to mess around, then by the time we are rolling around 25mph (I'm already in 2nd), I hear him roll into it hard. I do the same and the trans kicks down to first and starts boiling the 295s
(we never line up when I'm on the Mickey's)
He puts me at his rear quarter before I get into 2nd early and the car bogs a little. We lock up even until my RPMs pull up and I start pulling. I get nose to nose and am still pulling until he grabs another gear, he falls back by only inches and we lock even. My car hits third and he gets his inches back. I start to pull again after a moment and then he grabs another gear, once again losing a couple inches then pulling them back.
Neither of us wants to let out...we just stay locked door to door. I can see him cringing a little at how loud my exhaust is. Finally we are approaching a hill and not knowing if there could be traffic or a cop over it I lift and hit the brakes hard. I asked later and he said we were running 118-120mph last he looked.
Overall a very tight good race, the kind that are really a lot of fun.
Specs:
'71 Chevelle, cammed/intake/bolt on ls1, stalled auto, 295/50r15 street tires, 1 passenger/sub and **** in trunk, ~3900 lbs at time of race
'11 Mustang base GT with comfort package only, 3.73, 6 speed, MAC axle back, stock tires, 1 passenger, ~3800-3850lbs
Cliffs:
5.0 takes hit from stoplight 20-25mph roll, Chevelle spins then pulls even, cars lock up only moving during gear changes up to ~120mph.
Both cars have trapped 110-111 mph in 1850ft DA same track, same day

Yeah, his car frustrates at the track though. Between the **** wheel hop (even after some suspension tweaks) and just not being able to leave hard, his best is a 13.2@111mph.
Same day I was either spinning or babying out of the hole to run 12.24-12.3, if I can ever get the car to really leave like it should I will lose another .1-.15 in the 60ft.

Nice runs. From rolls those cars match up very well. Its always nice to get runs so close makes them very fun. Get a rematch with those mickeys stat. If he gets a tire out back it could get real interesting.

NIce run.
Although with comfort package and two passengers his weight is a higher. His car alone weighs no less then 3700. So with two passengers he least weighs over 400lbs. My car is a base model and weighed 3650 stock. Only option in mine was 3.37s.
Funny he having wheel hop issues. I never have had them yet. Even on a stock suspension. That was even launch at 6K on slicks. And 4500 on DR's.
With tranny the number that has had issues are small compared to the ones that haven't had issues. But if he going to have issues he should notice them around 3k miles.

He told me he weighed it at 3600 without him in it. Passenger was his g/f and he isn't big either (~160 and 120 being generous with the weights). If the scales he used were close then the posted weights should be really close. His is stripped other than the comfort and 3.73s, doesn't even have a wing. He also lost some weight ditching the heavy stock mufflers. Has the base wheels too.
My brother's CS didn't have wheel hop, but his '11 definitely does. So did his '10 GT and '10 GT500. I've seen a couple other '10-'11s at the track, a couple hopped and a couple didn't, it's weird.
He put in uppers and just made a trade for some other stuff...I think he said relocation brackets? Or maybe he put in relocation brackets and just traded for an upper, I can't remember. Either way he is trying to fix it.
His little brother is moving to town this week, with a very mildly modded Terminator Cobra. Look forward to some runs with him. (CAI, solid bushings, exhaust, and I think he just got a pulley and canned tune recently) At the track he ran a 12.3 on 17" drag radials and a light launch, trapped 115mph.
He will hurt me pretty bad from a roll, but on the street from a dig or low roll I think the tides will turn quick when I'm on the drag radials.

^you mean 3.73's right. I'm with ohio on the launching. I thought those mustangs pull out of the whole with little drama even on stock suspension. I could see if you had some power adders and the stock suspension hoping, but near stock should be pretty good out the hole.
seeing is believing so if you've seen some that hop and others that don't it makes me wonder if it would have anything to do with gearing as that seems to be the common difference other than transmission between stockish cars

Although since he has bought 3 brand new mustangs from the same dealer/salesmen in the last 2 years, you can bet your *** they would roll over themselves to fix his car if he had an issue.

Not sure if scale is right. Axle backs don't drop that much weight..
With tranny as willizm mentioned it isn't just the 5.0. The 5th gen Camaro had to stop production cause of an issue.
But on wheel hop same argument took place on modularfords. If the 2011 have or not. A bunch of us haven't had any while a couple have. Tell him his best bet though for wheel hop is doing LCA's, relocation brackets. Also we only have 1 UCA. Invest in some good springs. I like my H&R race springs. But i might switch to Cobra Jet springs.

Going to need to hurry and get my 799s on to keep these things at bay. Luckily most won't be driven by people who know what they're doing around here, but a well driven 5.0 (even stock) isn't anything to **** with if you have a fragile ego.
Of course you can always follow protocol and race them repeatedly until the trans strips the teeth off second gear. You'll win eventually
