0-60 in 3.8 seconds?
 

well more like 1mph to 60mph in 3.8 seconds :popcorn:

Tune is not final yet, will get a little power increase, 200 more rpms on the 1-2 shift, and loose about a 100ms from the shift time.

Should be about 3.6seconds with all the changes from a dig.

4x4 ftw :secret2:

thats with 750hp in a rcsb truck?

I have a datalog showing my 5.3 doing 0-60 in 3.60 seconds. 4x4 is great, isn't it?

Are you having 4x4 launch traction problems yet?

what! 3.6? how where what?

well I felt i was at the limit of the 4.10s before I started having issues on street tires in 4x4, so I swapped to 3.73 and a 2800-3000 with some added power :secret2:

its 800+ just not sure by how much, since I put on a new set of mods.

I found a 3.9, gonna dig for the 3.6.

0 mph.

60 mph.

If you're 800+ in a blown 4WD rcsb, theres more to be expected than 3.8 for sure. I pulled a 4.0 on the street last night at 11psi with the 4.8, and thats low boost :)

just to clarify things, this is 800+ bhp, but yes it will be quicker, on the 3.8s run I started from 1mph and sort of rolled on the throttle believe it or not lol, check out the throttleposition in the log.

Working on the shift speed and raising the shift rpm and will try again, I know it could easily do 3.6, but not sure if it would go quicker than this? This is with 7-8psi

So how much power does a 4.8 make with 11psi?

Should be a bit faster then that with 8xx hp. Using a calculator I came up with ruffly a 3.20 3.6 0-60 with far less HP, on 6lbs of boost( given this was at the track on slicks)

ok guys youre asking for it, ill go out in a while and log a run and show you it could do much better than this LOL, lets call this the teaser until its done, hoping not to break any driveline parts in the process however.
