Just wondering what the results have been using 2nd gear in an automatic to start...any good results...spoke to rpm ...they said no harm in trying...some have gotten good result some not.
Comments?

From what I heard, it would be a good idea to have a trailer nearby.

thx for the laugh....thats a good one.....so i guess rpm is trying to guarantee some reoccurring business

wasn't it jpee who was trying this to loose a 1/2 sec in brackets and it was working out pretty well for him.

Why would you start in any gear but 1st?? note .. if you say traction.. that's the problem.. fix that, don't band aid it..

Sounds like RPM is ready to give you a new or a discount on a new tranny!

Not sure how good of an idea it would be -

I say give it a try and let us know!

I am in for getting a good 60' time so using 1st is the way to go -

MAYBE a 2nd gear start would be good for a better MPH!

Thanks,Matt

Don't Arun launch at the track in 2nd gear?

4DRUSH

Yes, well he did

I launched in second with good luck.

It doesn't hurt anything. Might get the trans fluid hotter because the converter will run right up to stall speed and sit there until the mph catches up. You do need to remember to move the lever to 3 at about 5000 so the car can do the 2-3 shift for you.
It loses .6 seconds in ET but runs the same mph in my car.
Might not be a bad idea if on street tires.

No traction problem...fixed that....I've seen lots of really fast vettes on you tube and totally sound like 2nd gear starts.... Lets hope Arun comments on this one....

I've got a huge independent cooler with a fan ...so temps are not really an issue.....and I'm not going to be on street rubber...M&H 275/50/17 dr

It takes lots of HP to launch in 2nd gear and and cut a 1:38 60ft!! Arun

Figure I'm at around 850

1st or second its a gamble north of 800 ..with all the best ..ive broke with 650 na ..and had multi 9.3 ss in the same day all from 1 2 3 lock up they were all 800 to 900 na + no2

Arun@Dasilvamotorsports

You need to be making a lot of torque and power to utlize a 2nd gear. launch-and the converter needs to be built around the fact your going to launch in 2nd gear.

In your case I don't think it will work-there are much simpler ways to kill power off the line and ramp it back in.

King of the street knows what he is talking about...tried it tonight....not that great of a result...car left the line nice but died off....pathetic 7.3 1/8 mile runs.....regular first gear start got me a 6.4 1/8 mile run ..... And killed 8deg of timing from idle to about 4800... New tires held great considering no track prep....so I'm going to put that timing back in

Nice to hear from Arun! Hope all is well!

Thanks for the trial run and update!

Thanks,Matt

There are boost controls that allow you to adjust your boost output. For example, you could limit boost to 10LBS in 1st then 15LBS in second.
