For those of you with stalls around the 3000 to 3500 mark.
How do you launch? With the RPM almost to the tire spin point or just raise the idle a little? I was just raising mine to around 1500 or so with street tires and cut a 1.8 60' I have Nitto DR's now and want to lower my 60'

Thank's

 

Going to a 3500 stall so have the same question!

 

I have a vig 3600 and 420rwhp and BFG DRs...stock springs/shocks, Hotchkis control arms, panhard rod, both sway bars, and welded SFCs...I leave off idle but don't floor it right away...its kind of a "double-hit" deal....on the last yellow I half hit it until to nose comes up, then smoothly floor it...with 18 psi in the tires I've found this is the best way for my car to hook consistently in the low 1.7s..I've been a few 1.60s and some 1.69s, but all of the planets must have been aligned that day....It takes a few passes to get the rhythm, but it works--at least for my combination...

Sorry I have a 5700 stall and leave at 4500 off the transbrake.

It depends on how the car is set up but you don't always have to launch at high stall. Leaving off an idle lets the converter flash and doesn't hit the tires as hard. If you spin bad off the time, try launching at a lower rpm. If the car can launch at full stall just try bringing up the rpms a few hundred rpm at a time until 60' times don't improve any more. Holding the car with the foot brake won't always allow you to reach full stall because of the torque multiplication of the converter. The car's brakes can't hold back that much torque.

The purpose of a high stall converter is to allow the converter to slip at lower rpms which will allow the engine to climb quickly into it's powerband.

 

I have a Yank ST3800, ET streets, and a 2 step. From 2500 to 3000 it gets the best 60'. Anything more and it spins the tires before launch. Anything less and the 60' goes soft.

 

I stall my RPM's up too about 1,200 and let it "flash" It seems to hook better like that than stalling it up in the 2,000 rpm range. I have a Midwest 3,200 stall. My best 60 ft time doing that is 1.54 on 26X11.5 16" ET Streets.

 

Thanks for the impute it sounds like I just have to play with it a few hundred RPM at a time I would love to lower my 60' from to street tire 1.8 to a high 1.6 on the DR's.

 

I leave off idle.
I have had a ST3500 and off idle worked best for me then i changed to TH350/Vig 3500 and still leave off idle. The times I have left at 2500-3k it 60s worst than off idle...

But my best has only been a 1.65(N/A) with any set up. I need more gear with the Th350 ratios.

 

I just give it enough rpm to load up the stock rearend (1200 or so) and let her rip.I have a 3000 vig and run et streets.

 

I leave from idle on my Nittos, when I would stall it up it would launch harder, but it would spin.
