Avalanche opportunities

[gandolphxx]

Hi, I am a newbie - have an Avalanche 2500 - 4x4 - 8.1L. I have read all of the problems and suggestions, still have many questions.

 

I want this beast to really perform. To date I have:

 

1. K&N FIPK - not bad, kicked it a little - tight fit on the cowl.

2. Gibson single side cat back - nice sound - kicked it some more.

 

On order:

 

1. "The Other Guys headers" - 1/2" flange - should eliminate any problems.

2. Yank 2600HD torque converter - should kick some more at the low end.

 

Wish list:

1. Whipple 8.1L Supercharger - after the new year - hope to see one in two weeks on another guys lucky truck.

 

What else would you experienced guys reccommend?

 

Topic2:

 

I have Mickey Thompson 16x8's - can only handle Firestone 265/75's because of wheel wells - tight as is. Don't want to raise suspension - but willing to take body up max 3" - will this help fit 285/75 Interco TRXUS. Will a body lift screw up towing [gooseneck excluded] - change bumper mounts?

 

Thanks in advance for all thoughts, criticism, etc.

gandolphxx,

 

get in touch with Tbyrne from Tbyrne motorsports.  He has a 8.1L Suburban on order and is going to do some major mods to it.  His Sub is the same chassis as your Av so you two can get together and talk about all the "big stuff".

 

He plans on supercharging his "burb" and that probably means some extras like headers and intakes and computer programming.

 

get ahold of him at ...

Thanks - sent them two Emails - never got a reply - found a local http://www.motorsporttech.com that really seems to know their stuff - they are the guys doing the supercharger bolt on.

lower it     thats how

[gandolphxx]

I admit to being a newbie, please explain or aim me to how that will help fit larger tires - or am I missing the point? I would no like to give up the 4x4 clearance that I have - streets in Houston are atrocious.

lose the big tires  throw on some 20's  thats how

I think LarryE is wanting you to put it on the ground. I see posts about these Whipple superchargers, do you have to cut a hole in your hood for this? You must really want some serious power since you alredy have the 8.1L.

I am trying to figure out how to have it both ways - a 4x4 and power - The Whipple bolts on with no hood mod - looks like it fills up the front end though.

Big and fast is easy if you have the money.  A 4-6 inch lift with 33-35 inch tires is all you need.  After that the supercharger is a direct bolt on although voiding the factory warrenty.  Make sure to adjust your ring and pinion for the taller tires and you should be able to smoke the bigger tires all day.  Plus if you can keep your foot out of it you shouldn't lose much, if any mpg.  

Come on ryr8828, the days of the roots style blower sticking out of the hood are all but dead.
