Nathan! So what did it run? Don't keep us in suspense.
Also, You have to know that after too long a buffering time, because of my dial up connection, I am able to watch your video with no hitches, glitches, or hesitations, even in full screen mode. Remember what you did for my memory and be informed that it worked. Thank you again.

my best was 13.2 or 13.3 that I heard.. I just couldn't get out of the hole and had no traction in 1st or second. If I tried to crawl out of the hole the car would just wheel hop like hell and bounce me all over and if I tried to come out a little harder it would just light up in smoke. I couldn't find a happy median yesterday except once, and my time wasn't recorded.. this video was my best run of the day by far but they didn't record my time for some reason. Something with the lights or something missed me. The GTO was running 13.2 - 13.3 all day and I think this was my best overall launch, bad wheel hop and spinning at the top of 1st and second bad but it somewhat stayed straight out of the hole... You can see when my 3rd gear hits I start hooking and pulling hard.. No idea what I ran though, my car just LOVES top end, keeps pulling harder and harder the faster I go.. the 1/4 mile needs to be a little longer, just for me.. lol i154.photobucket.com/player.swf?file=http://vid154.photobucket.com/albums/s259/LoganGTO/wendover/cts-vwon.flv

yeah it was REALLY bad yesterday.. the hop was scaring me..
I am done racing the car until I have drag radials on it and the BMR anti wheel hop kit. they say it reduces wheel hop by 75% without affecting ride quality, I guess I will find out. Not sure what else to do.
I think I just found the potential of my tires at the track, not my car.. Just like my friend jeremy in his nissan.. he can be at 15 lbs of boost or 25 lbs of boost and he cant do better than 13.3.. kinda funny how thats exactly where I am stuck too..

I'm not sure what the BMR anti wheel hop kit is, but I imagine it will help. Vince says the IRS like yours doesn't respond to drag radials that well. He claims that you need the softer sidewall of a bias ply slick that will wrinkle and absorb some of the shock to avoid the wheel hop. It appears, however, that you are aware and on top of it.

It looks like a Pretty stout kit. Have you thought about designing a kit of your own? Take their kit, and make some changes to use the Energy Suspension Urathane (How ever you spell it) bushings, and design your kit around there, and then return their kit unused. I bet you could pretty much prototype your kit, and install it, have a test vehicle running it, and be about the same money, but now you could be the other guy out there offering a kit. Just find someone that can draw up a set of plans for it, and have a machine shop build it, (Or get Shawn to get a small bridgport, and produce them inhouse). You say that their kit is the only kit available. Wouldnt it make sense that a second kit would be a good thing in this market?

I agree. If that were my car, I'd buy the bushings and start there. It looks like the kit in question is mostly bushings w/the lateral support bar for the sub frame. How much flex/bounce is there that far forward on a non-arm? Not much would be my bet. But building that bar would be cheap and easy anyway. I also think the pinion support would help a lot. IF he ran a 13.2 -13.3, then you ran upper 12's easy on that particular run. You smoked him good.

I was looking into the pinion support as well and I do have that little " clunk " they talk about and they say it fixes it.. I was going to buy that support brace for sure. I am just torn up on what to do in the rear first for the hop..
I know the wheel hop issue is fixed under the GM 50K warranty, but I just missed it. I am 53K.. They supposidly replace the bushings and it seems to fix it on a lot of cars. I am trying to get a hold of a parts guy at GM to see how much they would just sell me the bushings for that they use in the warranty work..

Interesting, Young Chev said the fix is not for ANY suspension components, just replaces the rear body mount bushings and supposedly helps.. My cost is $130.00 for the bushings.. I am wondering if it is the same thing as the BMR bushing set for $199.00 ?
