jdeprato Posted May 11, 2013 Report Share Posted May 11, 2013 Has anyone tried starting off in second gear when launching? I'm wondering if that would help with the launch. Quote Link to comment Share on other sites More sharing options...
shoman04 Posted May 11, 2013 Report Share Posted May 11, 2013 Good thinking but it will not work in our car. If you go to manual and 2nd you are still in 1st but the trans will try to go to 2nd as soon as you start moving.(DCT w/tor-convertor 1st) Not sure how bad that would be on the trans too.!? Best I know this is true. Quote Link to comment Share on other sites More sharing options...
jdeprato Posted May 11, 2013 Author Report Share Posted May 11, 2013 Yeah I haven't tried it myself. Just wondering if it would help with the launch. Quote Link to comment Share on other sites More sharing options...
ShoNuff Posted May 11, 2013 Report Share Posted May 11, 2013 That might make sense if you were in a lighter weight 500 plus RWHP stick car. On a heavy 4 door AWD car you should have no worries. I launched by brake tq'in around 2500 RPM. Drag racing is ALL in your 60 ft time and if that's slow you will be slow. So here is what I rec'd having just been to the track....traction control off, sport mode, launch from 2500 RPM. Quote Link to comment Share on other sites More sharing options...
jdeprato Posted May 11, 2013 Author Report Share Posted May 11, 2013 I can't get traction launching without feathering the throttle. So I'm not sure how you are launching how you are describing. Is your car PP? Do you have the H&R springs? What tune do you have? Quote Link to comment Share on other sites More sharing options...
jdeprato Posted May 11, 2013 Author Report Share Posted May 11, 2013 Okay so today the temperature was in the 80s and when I hard launched I didn't have the same traction problems. So either the car made less power or the tires were a lot stickier with the extra beat or a combo of both. Quote Link to comment Share on other sites More sharing options...
ShoNuff Posted May 12, 2013 Report Share Posted May 12, 2013 Stock tires, non pp, livernois tune, kn intake....how did u run? Quote Link to comment Share on other sites More sharing options...
jdeprato Posted May 12, 2013 Author Report Share Posted May 12, 2013 I wasn't at the track just on the street. Definitely had better traction with the warmer weather. I plan on hitting the track once I install the methanol injection and the catted downpipes. Quote Link to comment Share on other sites More sharing options...
ShoNuff Posted May 12, 2013 Report Share Posted May 12, 2013 Yes. Im gonna do catted down pipes next as well but no meth Quote Link to comment Share on other sites More sharing options...

HighBarSHO Posted May 12, 2013 Report Share Posted May 12, 2013 How many miles on your Goodyear F1's? I have owned a few cars that came with these from the factory. All of them turned to crap much over 8-10,000 miles. Yes, when it is hotter outside you will have more grip. Livernois says 1700-1800 rpm brake boost and go in "D" drive. Let the transmission shift for you. Quote Link to comment Share on other sites More sharing options...
jdeprato Posted May 12, 2013 Author Report Share Posted May 12, 2013 I have run nitto dr and mickey thompson on a couple of different mustangs and they worked great once I heated them up but we don't have that luxury with this car Quote Link to comment Share on other sites More sharing options...
dmharvey79 Posted May 13, 2013 Report Share Posted May 13, 2013 I had no traction issues standing on the throttle (2500 rpm brake stand) off the line with all-season tires and temps in the low 50s, TS/SC all at normal settings. As a matter of fact, the car is bone stock and it ran a 13.499 at 103.6 (1.983 for the 60' time). Quote Link to comment Share on other sites More sharing options...
jdeprato Posted May 13, 2013 Author Report Share Posted May 13, 2013 My car isn't bone stock. The tuning makes a big difference in regards to traction. Quote Link to comment Share on other sites More sharing options...
boltmann Posted May 16, 2013 Report Share Posted May 16, 2013 I have always found that street tires always bite better on the street vs. the strip. Imo Quote Link to comment Share on other sites More sharing options...
jdeprato Posted May 16, 2013 Author Report Share Posted May 16, 2013 Yeah I mean that has been my experience as well. When the track isn't prepped well though that also doesn't help. And you want to stay out of the water box with street tires also. Quote Link to comment Share on other sites More sharing options...
homer Posted May 17, 2013 Report Share Posted May 17, 2013 you seriously would want to start in 2nd and bog than to spin a little in 1st? Quote Link to comment Share on other sites More sharing options...
jdeprato Posted May 17, 2013 Author Report Share Posted May 17, 2013 I get serious wheel hop at times depending on the temperature outside. Today was warm so it wasn't as big of a deal for example. Quote Link to comment Share on other sites More sharing options...
homer Posted May 17, 2013 Report Share Posted May 17, 2013 traction bars? something to stiffen it up? you will go faster spinning that bogging. My 5.0, we changed the upper and lower control arms and got rid of the wheel hop Quote Link to comment Share on other sites More sharing options...
jdeprato Posted May 17, 2013 Author Report Share Posted May 17, 2013 I think someone on here has already had some front end suspension pieces made and they made a difference in his launch. The reason for my question about the 2nd gear launch is because with the PP transmission the shift points occur so quickly I was just curious to see if anyone had tried a 2nd gear launch. Since the torque curve starts at such a low RPM and the PP gearing is also very low, it seemed plausible at least for someone to have tried a 2nd gear launch as a test. I believe SHOMan commented though that the transmission while allowing you to shift into 2nd gear while stopped (I know it will because I tried it, just didn't launch from 2nd) the car will quickly down shift back to 1st thus not allowing you to launch from 2nd gear.
