What RPM are you launching at?

[oktw88]

What do you guys launch at on slicks?

My car is NA with cams, exhaust, gears and suspension. What would be a good RPM to launch at on slicks at the track. My best ime right now is a 12.96 @106 with a 1.88 60ft spinning some because i had my tires at 26PSI..

 

[fin1]

stick or auto?

 

[oktw88]

5 speed

 

[chad05gt]

5000ish... depending on track prep, cond, the sun, Jupiter, ...

I was leaving at 7000 RPM WOT on days when the track prep was dead on. Dumping, not slipping. If prep was off, I would still leave at 7k WOT, but I would slip it like a mo fo! LOL My best short time was 1.68.

I would get just a little wheel spin (barely a chip or two). Without a TruTrack LSD or locker, you may not be able to pull that off though.

Slick M1 compound tires at 14 PSI hot (10 cold). It was some seriously scary stuff on the big-end. The trick is to make sure the tires are good and hot so they balloon to 14 PSI or the bead will break loose.

At 3800 lbs, I had some advantage with traction...

or wheel screw those suckers in there....or set them to 12 or 13ish and do a lighter burnout which mickey thompson recommends

 

[marcspaz]

Also good options...

Yes the stick and auto are both 5 speeds. Standard or auto is the question lol

+1 I leave @6500 and shift@6500 w/28" by 9" goodyear slick @14 lbs and I get approx. 1/2 turn of the tire, 1.57 60" wheels up and ass down. lol

 

[Matt D]

I launch at 6200rpms

26x11.5x15 et street

stock posi, stock clutch

 

[jp's performance]

6800rpm 26x11.5x17 bias ply et streets.1.62 60ft 4.30's stock clutch and posi stock driveshaft

 

[dragpac]

I have a tru trac posi,stock clutch and drive shaft.and yes I'm suprised my driveshaft is still holding up.

 

[Matt D]

I need to buy a tru trac... lol

 

[SlvrS197]

i have stock posi, and d/s and i usually dump it at 6000-6200
on 26x11.50 ET streets 1.60 60's

^^ Bitch. lol.

FWIW, not that anyone here gives two shits, but launching an NA v6 with the stock 18" BFG's, stall at just under 3K and dump the clutch. I've seen a 2.2 60ft with those. A friend of mine who used to have an 07 4.0 hit a 1.9x 60ft with ET streets on stock 16" v6 wheels with only JLT, AM tune, T-Lok, and 3.73s. I can't wait to put my spydershaft to the test by January..

 

[circusboy]

Last time at the track I was leaving at @ 5000 RPM, on ET Streets and skinnies up front. no slip, just dump and go, lol. pulled three 1.6's 60' in a row.

Now for my question, lol. I'm now Turbo, should I launch any different?
I was thinking maybe at the RPM that I'm making peak torque or should I just let here eat

 

[Freaknazty]

3700ish was my sweet spot....... less gear than you though but on 25" tall tires ......last time out at the track I was dumping it at 6k ( just couldn't get those damn shifts right though lmao )
