What RPM are you guys launching @? (Si)

954K20_SI · 03-25-2006, 08:50 PM

Ok I still don't see how some of these 06 Si's are running 14.9~14.8 bone stock? My guess is these guys gotta have the summer tires b/c these pilots suck! My best run stock, was a 15.3 and another FG on here ran a 15.0 what RPM are you 14'sec stock people launching at?? I tried 3 grand and spin like a mother..no grip..well my times should be much better later this week after some more goodies go on

Ive been launching 2.5-3k, around there, but thats only when someone wants to race.

**twistedframe** · 03-25-2006, 11:49 PM

me too, but even at 2.5-3k i still get a good bit of tire spin. (damn crappy all season tires)

endless254 · 03-26-2006, 02:35 AM

My 14.9 was with the stock all season's. I launched at 4k.

celery gt-5 · 03-29-2006, 01:15 PM

yeah u need to launch higher then 3k with a low torque car like the Si. i bet 5k would work pretty well.

**twistedframe** · 03-29-2006, 01:23 PM

at least for me 5k give me hella tire spin. granted i'm not the most experienced drag racer.

You dont want to spin the tires hardly at all when launching, that's what slows you down.

celery gt-5 · 03-29-2006, 01:28 PM

well u gotta feather the clutch, but idk from what i hear i-vtec gives u guys more low end torque then one would expect a 2.0 to have. I would think w/ the LSD and fairly wide tires u guys have u should be able to launch fairly high. an experianced racer i talk to said when he would launch his brother's prelude he would just rev it to just below vtec and that gave them the best launches. He ran 14.87 w/ a stock spec v and 14.1 or 14.2 with a 6 speed maxima w/ just intake

my car needs to be launched real high to get good times, but i think u guys have a good amount more low end

obviously. thats why u slip the clutch

**twistedframe** · 03-29-2006, 01:31 PM

thanks for the info!

celery gt-5 · 03-29-2006, 01:46 PM

i suck at launching..lol..idk maybe its my car, but if i launch at 3 or 4 it takes for ever to get into lift(toyota vtec)

Ep3racer954 · 03-29-2006, 04:19 PM

i believe 4k is the magic number... thats what i used to run 15 flat.. just gotta work on those 60' times! ahhhh traction traction traction!!! if only i knew what that was!! lol

60103 · 04-16-2006, 10:39 PM

on the traction topic, what psi are you guys running in your tires at the track?

Launching at five doesnt work.... I say anywhere between 3.5-4k. Anything after that is just a waste of tire and anything before that, would put you way before vtec once you take off.

bw787 · 04-23-2006, 01:09 PM

use 20 psi in front tires and upped it to 40ish in the rear. get some azenis and watch those 60ft's dive.......
