ET and trap speed issues with ls7 clutch
I have searched and read all I can with no for sure answers found, but I always get a for sure answer when ive posted issues here. The problem is still same ET as stock but 7-10mph gain...2001 WS6, T56 stock down to the cats and exhaust and just a lid/filter,street tires in 2008 I ran 13.18@101mph with a 2.0 60'(launched @2,500 no spin). In 2009 I had a spec stg 1 clutch,LT headers,ORY,built T56,pro 5.0, bald street tires and I ran 13.07@111mph(only gained .1 tenth from stock but 10 mph) 2.10 60' (launched off idle and spun thru 1st and part of 2nd), that clutch went out a week later with just 3500 miles. Then in 2010- installed LS7 clutch kit and new fuzion street tires and ran 13.00@109mph, launched at 2500rpm and it bogged out the hole with 2.0 60'. This year I installed full rear suspension,CE rear 3 way drag shocks,nitto555 xtreme perf street tires,BMR trq arm,A/C system removal,AIR removal,front swaybar removal, solid pinion spacer,4.10 gears,welded tubes,alum rear cover/girdle,drill mod and car feels much better except my 1st run I launched at 3k easing out slow and the tires didnt even try to spin and it didnt throw me back like on a street launch, then shifting into 2nd my rpm's only dropped to 5,500 from 6k redline and I had to shift to 3rd very quick and the same thing happened, then again in 4th and finally into 5th crossing the 1/4 @5,500 rpm in 5th!?!? 13.01@109mph 2.2 60'. Ive never got into 4th with 3.42's. My last 7 timeslips from 2 years ago were all 13.0@109-111mph, now with 4.10's and suspension and full boltons, built t56 and no traction or shifting issues I am only .1 tenth ahead of my stock ET and 8mph with 4.10 gear? I havnt found anything about the ls7 clutch not holding a 340rwhp LS1, but many threads on ls7 clutch and issues launching. What do you guys think/recommend? Also on my 2nd pass this week I launched at 4k and the shifter moved a couple inches and popped outta 1st when I let the clutch out and I went back in gear and gave it hell and with a 3.6 60' I ran 15.0 @ get this 109MPH!!!!???? What is going on? My motor mount on pass side has the rubber split in 2, I have new poly mounts not in yet and already have poly trans mount on car. my clutch budget is no more than $500-$600. Thanks in advance and sorry about the long post.

Idk.... I'm running 7.60 in the 1/8th on Hoosier qtp's, they're slipping, not my ls7 clutch with 30k on it. 1.68 sixty, 91mph trap. Moser 9" 3.89 gear. I can't complain about my ls7 clutch.
