fastbird232 Posted February 9, 2006 Report Posted February 9, 2006 The idea has been kicked around in my car club for a trip to Mid Michigan Speedway this summer. I'm wondering what I'll have to do to the car to get it ready for some 1/4 mile flogging, in terms of both performance (to go as fast as possible) and reliability (so I don't blow something up in the process). Also, what's the best sport-shifting method for a the LQ1? Quote
5speedz34 Posted February 9, 2006 Report Posted February 9, 2006 Umm, put it in drive and hit the gas? I would just make sure you all the maintence things done and it's running tiptop. Make sure you have good tires, and struts as those will help your launch. Quote
Prospeeder Posted February 9, 2006 Report Posted February 9, 2006 Torque brake it up to what, 3k? And then let off the brake and slam the gas to the floor Quote
Justin Posted February 9, 2006 Report Posted February 9, 2006 Leave it in 1 until the 4T60E shifts it into 2 for you, you'll gain some rpms in 1st that way. Quote
z284pwr Posted February 9, 2006 Report Posted February 9, 2006 Leave it in 1 until the 4T60E shifts it into 2 for you, you'll gain some rpms in 1st that way. Don't you mean in 2nd? I will say make sure the car isn't super hot. Ice is your friend as well Quote
1990lumina Posted February 9, 2006 Report Posted February 9, 2006 I'd be more worried about the tranny then anything....the LQ1 vehicles have tranny coolers right?? If yours for some reason doesn't, I'd add one. Quote
THe_DeTAiL3R Posted February 9, 2006 Report Posted February 9, 2006 Grippy tires on light rims... lower the tire pressure for better traction Get your e-brake working so you can do proper burnout beforehand... Just be easy on your trans, maybe take a break between runs... Although I beat the piss outta my old 2.8, I'd go run after run after run, and that 4T60 held out no problem. But that was only like 130hp Quote
99RegalGS Posted February 9, 2006 Report Posted February 9, 2006 Leave it in 1 until the 4T60E shifts it into 2 for you, you'll gain some rpms in 1st that way. Don't you mean in 2nd? No, he does mean in #1. It shifts about 100-200 rpm later. Quote
fastbird232 Posted February 9, 2006 Author Report Posted February 9, 2006 It'll shift itself into 2 if I leave it in 1? Quote
99RegalGS Posted February 9, 2006 Report Posted February 9, 2006 Yep, but it will not shift into 3rd. You have to put it in D or OD to get 3rd gear. Quote
fastbird232 Posted February 9, 2006 Author Report Posted February 9, 2006 Good to know. I had no idea. Quote
Psych0matt Posted February 9, 2006 Report Posted February 9, 2006 Good to know. I had no idea. :withstupid: Quote
Bossman429 Posted February 9, 2006 Report Posted February 9, 2006 Don't drive through the burnout water if you don't have slicks. Go around it and spin the tires a couple revolutions to warm them up, and get all the debris off of them. Quote
Tru2Chevy Posted February 9, 2006 Report Posted February 9, 2006 Play with front tire pressure to get the best traction. Don't take regular street radial tires any lower than ~25psi, or you will end up hurting traction. Air the rears up to 50-60 psi when you get to the track. This will help your rollout a lot. Make sure you remember to air them down before you leave. Take as much weight out of the car as you can. It will allow for faster times, and it will be less stressful on parts. Keep your hood up between runs to get the engine as cool as possible. Use a bag of ice if you want. If you are racing on street tires: if you can avoid the waterbox, do so. If you can't, drive through as slow as you can so that water won't splash into your tread or up in the wheel wells. Once you are past that, just hit the gas hard enough to spin the tires over 2 or 3 times. You aren't looking to get any heat into them, just need to clean debris off of them. Have fun! - Justin Quote
NeonKnight Posted February 9, 2006 Report Posted February 9, 2006 Go check out ZZPerformance's website i think it is a 96 or 97 grand prix GTP that runs 9.7 seconds smoked a supercharged viper hahahaha was good stuff. Quote
fastbird232 Posted February 9, 2006 Author Report Posted February 9, 2006 96 or 97 grand prix GTP Kind of a big difference, there. Which was it? Quote

Have fun! - Justin All good info. Thanks, guys! Now I just have to keep this thread bookmarked so I don't forget by the time summer rolls around... One question I did have: my 4T60-E was completely rebuilt two years ago. Is it strong enough to handle a couple floggings at the track still? Quote
5speedz34 Posted February 9, 2006 Report Posted February 9, 2006 One question I did have: my 4T60-E was completely rebuilt two years ago. Is it strong enough to handle a couple floggings at the track still? Ohh yeah, it should have no problems, especially if it was rebuilt. Quote

THe_DeTAiL3R Posted February 9, 2006 Report Posted February 9, 2006 I didn't know that about the waterbox... thanks for that info Quote
GP1138 Posted February 9, 2006 Report Posted February 9, 2006 I didn't have any problems with my wonderful 16.8 Grand Prix. The 4T60E keeps coming back for more and I flog it every day. I have no mercy. Just take everything out, including the spare. Quote

chadz34 Posted February 10, 2006 Report Posted February 10, 2006 Good to know. I had no idea. :withstupid: I didn't know either, I thought it'd stay in first and hit the governor??? Quote
fastbird232 Posted February 10, 2006 Author Report Posted February 10, 2006 That's what I thought, but I haven't gone out and tried it yet. Quote
