Hey I have a 2005 Escalade EXT 2 wheel drive converted with a built 4 L 80 e transmission with a 3600 stall triple-disc Billet Circle D transmission with a Eaton posi Detroit truetrac 4:56 rear end. I have a 408 Stroker iron block forged LSX engine it has flat top pistons with valve relief from CP Carrillo. I currently don't know the compression ratio I think it's at a 10.5 up to 11.1. My plan was to get a LSA supercharger from a ZL1 but was told since I have a 408 stroker I should look into getting a bigger supercharger like Whipple 2.9 or some other type of roots style since my truck weighs 6060lb that's with the heavy wheels and 400lb audio system. I also been recommended to do turbo but I'm not a fan of Turbo and having to spool it up. My truck is a daily driver I'm not making it a track truck just Street and strip mostly Street and to have fun on daily drives. So what blower do y'all recommend me getting?

 

Then do the LSA blower. It'll provide plenty of pep. No need to reinvent the wheel here.

 

ok so stick with getting the 1.9 LSA?. I didn't mention info wanna kick *** when I do go to the strip lol.

 

with a 3600 stall I don't see you having any issue lighting off a decent sized turbo

 

Nice truck!
#1 TVS 2650
#2 Whipple 2900
#3 TVS 2300
I personally wouldn't consider anything else except possibly an Edelbrock but I don't like it as well. Whipple is the **** imo lol.

 

You're opinion is biased.

The problem with him using the Whipple 2.9 is:

1. They're built for rectangle port heads

He'd have to swap heads or using adapters. I don't know if the newer trucks have the same spacing as the NBS setup. That could be an issue as well.

 

You can get them on cathedrals... I have a 2.9 on a 4.8 right now


tell me more about your cam and converter. Honestly a direct drive procharger may be a good option for you. A high compression 408 with a decent stall speed... when you hit it off the line with any type of boost you will flash it to 4500 at a MINIMUM. A decent procharger would already be making some serious steam there. I have a feeling it will be the best fit to some of the key parts you already have.

 

I am biased lol and I have to revise because I missed the stall being 3600. It would BLOW through the fun part of a pd blower so no bueno unless you change the stall out or have it tightened. Agree with above, a PC would be a hell of a lot of fun and also would probably have lower IATs. I would go big enough though not a P1 on a 408.

 

Wow email didn't notify me of replys!

 

yes I know, I'm looking into a L92 heads or prc ls3 heads
