Save RPM for Boosted Launch

Safe RPM for Boosted Launch

So I was doing a little messing around in the back yard last night and thought I would use the 4 wheel drive since I havent done so in a while. Did some 4wd launches and wasnt able to build any boost till about 2100 rpm. Is this a safe rpm for parts? Whats the max one can go? I was on grass so I can see slightly less resistance than the drag strip but is that a safe level to boost at?

What all is done to your truck?

You sure.....oke:

 

[caladash]

At what rpm should I worry?

 

[STROKIN N STYLE]

are you trying to figure out where your truck launches the best?

I was launching at 2100 with a completely stock truck (except tune), I think you are ok.

I think you should be looking more at your boost instead of your RPM's. Leaving under 20psi and you should be okay. If it breaks something, it needed to be fixed anyway.

I am. The first launch I did didn't feel as strong as I thought I should so I did another. The first one didn't even move the boost gauge. The second one I built about 4psi but that was at like 2100- 2200 rpm. Just felt a little high but launched nicely!!

build it up to about 15psi and let her rip...

just don't leave anything on the dash or in the cubby hole above you.

when i drag raced a couple times a few years ago i had a 2100 stall tc and would flash it to 26-2700 on launch. lol launched the rubber bed mat out on the track one time.

worry more about boost pressure than the rpm... try leaving at 10psi, and go up from there. when i was running a smaller charger and a stock stall converter my sweet spot was around 12-15psi

 

[caladash]

Tried about 6 psi and it felt pretty nice!! Not even sure I could do 15 psi!!

That's my philosophy. LOL

Now Danny you break everthing you touch..... So how can you call that a philosophy....

I think it depends on what kind of landscaping you have in the backyard.
