La Guera Is SUPERCHARG AND CAM

[tx tahoe z71]

I'm at 2000rpm at 70 with 30" tires (275/60 17) with my 3.73's

Checked this morning and I'm running 2400 rpm @ 70mph.

Thats about what cruise at with a locked converter, 4000 rpm stall converter, 4.88s, 32" tires behind the vMax engine.

Travieso you have a nice setup. You have to think, you have a twin screw supercharger, you make broad power, you have instant tq. You dont need a low gear. Maybe 4.30s max. If its on back order get some 4.10s.

High rpm combo that I and others may have, well a centrifugal style supercharger be better and take advantage of the fast rpms. Something like a Procharger for me D1. Makes for a mid-top end killer. But its awesome cause your still geared low. Wicked.

You are so right Man, I've been so indecisive/confused about what gears to go with, the truck will only see the track maybe 2-3 out of the year, it's mostly a weekend truck and i do take the truck for long trips, it would be very annoying to hear my exhaust or the truck revving at above 2500RPM, does of you know, having a Supercharger/Longtubes and No Cats with a 3 inch exhaust gets very loud.. But then again would i really notice the difference with 4.10's ? is the question i would like to know.. I've driven my buddy's truck with 4.30's on a 32" tire and the truck felt really responsive.... HELP !!!!!!

Man, thats nice. Soooooo any vids yet?

Here you go...

Should have alot more in it than a 9 sec 1/8th given your mods even with the 24's. Who is doing your tuning? You had it on the dyno yet?

yeah the 24's do take a toll on parasitic drivetrain loss, but i've always had a thing for going fast and looking good, anyways On November 4th a couple of buddy's and I are gonna be going to Famoso Speedway i will be removing the 24's and rolling either with some 17's-20's i should have my gears and TruTrac by then and we will see what she really does on the 1/4 Mile im shooting for low 13's

My Tuner is a local Tuner know as Wottuning Had some Issues with Justin, that's a different story but He's got it dialed in Very Good.

Nice, in for results! You have it tuned for E85? If not, you should look into it if you have access to it. Might have to up the injectors, I'm on 75# ones and they're at their limit.
