Optimum take off for auto?
So i was out today messing around and i was wondering
If you use the "Low" gear to take off and hold the brake to "boost" start is that quicker? but then in what rpm range are you to slap it in 2nd, then Drive?
I'm going to be taking my car to the track soon down in rockingham and wanted some opinions.
What do you guys think an SC400 with a cold air BFI, K&N filter, and deleted resonators + magnaflow muff's will pull? I'm on stock rims as well.
Thanks in advance guys

That is what i figured. But really can't you just go as high with the rpm's as long as you keep the tires from breaking loose? I guess that depends on your tires though.

yeah you can go as high as you want the better tires you have the higher you can go.. the other night i could only get up to about 1800ish before the rear tires broke lose but it was also cold.. in the end it is up to you

ahhh, ok yea i get up to about 3,000 rpms but it still feels kind of sluggish but that's why i am replacing my dying cats.

The trans ECU will shift at 6k rpm even at WOT. The 'L' position will allow you to roll up to 6250 (stock redline).
Two things:
(1) Peak power is at 5600rpm on the stock fuel map. The farther you go into the rev range, power output actually starts decreasing.
(2) If you are able to have the presence of mind and the dexterity to shift into 2 between 6000 and 6250rpm: great. But, shifting like that, you will be risking hitting fuel cut by bouncing off the rev limiter.

i launch around.. 2.5? abuot there.. when conditions are perfect..
tires/rims play a big roll :] wider ur tires the better (in general)
this is what i do im sure it will work
right after u launch.. when it hits around 3k-3.5k i shift to two.. (with it still 100% gassed) also press that lil button behind the gas pedal.. it will shift PEFECTLY.. and not redline or preshift or w/e its called
