Kenne Bell or Whipple on 8.1?

Lots of chatter on here about this topic, but I have yet to find anyone who has the Kenne Bell. Anyone? bueller...

Kenne Bell only will program if you have the 4L80e or 4L85e...no programming for the Allison. I've been running the Whipple for a while now with not one problem..very straight forward install and a very good kick in the pants too.

Ah, thanks for the info. Nice truck!

Do you have the intercooler addition?

No intercooler...left it off incase I wanted room to grow...still plenty of power without it.

8100HD,

I dont want to start a big supercharger discussion here in the wrong thread, but can you give me a thumbnail on the supercharger install and upkeep? I am REALLY flirting with the idea of adding a supercharger to my 8.1L. What is the basic install like? Did you do yours yourself? I just sort of cringe at the idea of making all the changes needed to add the supercharger. Injectors, wiring mods, new PCM flash (already have the Westers), adding the oil lube line/tapping the oil pan, and whatever else. Is there any upkeep other than the basic 3 month/3000 miles routine? Is the power increase enough justification for the expense? Any other info you may have, or things you would have done different?

Well stated, I have all those questions as well. This is my daily driver for the next year or so, and I don't want to create a pain in the arse.

Okay if I miss something, just ask again..After many searches and read threads on many boards I decide to go the Whipple route last year. Arrived at my door without a problem, unpacked it and took an inventory of parts. figured out when I was going to make time for the install and sat down with the install instructions and a cool six pack..I would re-read them off and on for the next couple of days...when the install day came I awoke early to get the truck and head to my shop, I started wrenching at about 9 am following the instructions to a T. Everything went as planned. The splicing into factory wiring was a cake walk, being MECP certified and playing with vehicle wiring for about 14 years now. The instructions from Whipple are very complete and very understandable(if thats even a word) Well I got to the point where I was going to turn the key at about 10pm that night...talk about nervous, she fired without a problem and has been running flawlessly ever since. Since the Whipple compressor is a sealed unit it has its own internal oil that I change at about 5k originally, but plan on stretching the interval a bit more...no tapping the pan and risking a metal chip in the pan. I am running the Whipple kit as it came in the box, which I reccomend to everyone except the guy who needs every single HP out of his motor...my feeling is that when you start messing with their package and changing injectors and tunes you start having some problems, but when set-up as designed by them it runs problem free. I have the 2 additional injectors and the Whipple FMU, put it on a wide band and my A/F ratio is right where it should be. The power increase is like no other mod you can do..it is a complete rush..along with the charger I also have TOG headers, Flowmaster cat-back, DirectHits ignition, modded mafs, and a factory airbox with Whipple mods. I can roast..I mean ROAST my 35's...even at 20mph and punch it she lights 'em up. I still run factory 3.73 gears and tow 8k at times...what a difference As far as numbers go, put it on a dyno this past summer, about 85-90* out with some good old Northeast humidity and rolled a 360/452 with my 35's on....thats hanging right up with a Hot Juiced Dmax...plus I got the cool factor...there is no mistaking my truck coming down the road...nothing sounds close to a Blown 8.1 whining away...let me know if you have anymore questions.

8.1

I've been pondering a Whipple for some time but the new direction I've gone its not a big enough compressor. Never the less a good right up there 8100HD
