I've got a Powerdyne on mine and thats because I couldn't pass up on the deal I got. I've never ridden in any other vehicle thats been supercharged before. You can't feel it kicking in till around 3000 rpms and up. Then it feels like a powerband hitting on a dirtbike. I got this one cause I thought it might be better since it doesn't start working till later in the power range. Of course I wish it had more, but I am satisfied with it. Hav'nt raced it since I put it on yet, but I am hoping on doing it very soon.

 

Being A Combination motors Turbo owner myself
I would say that this a a prety advanced kit for the do it yourselfer
It has some Kinks to be ironed out yet
But nothing Seth isn't working on
Parish and I have the very first kits out so there were a few hickups with things
The potential of this kit is pretty Crazy for sure
I Plan on pushing things further than Parish

 

Uh oh parish, those seem like fighting words

 

Hey GMC Ski or Parish

I was seriously looking into getting this set-up and am curious if you can elaborate on "It has some Kinks to be ironed out yet". I want to know what i am up against.

Thanks

 

Nothing really huge for me there might be a slight fitment issue with the 4wd version of the kit
With the Cross over and such only on 4wd vehicles i think seth has since changed the design
GM has a different designfor all of the trucks it seems
I'm a 2wd and had no issues with the cross over exhaust pipe
For me i was missing a few pieces with the kit no biggie as Seth shipped them next day express
Other than that it's a tight fit for sure on the passenger side
I would say give Seth a call about the kit for sure very easy to talk too with any questions

What are you going to put it in ?

 

I was going to put it in an SS silverado. I was also looking at the STS kit, but am waiting to get some results on that kit for the 6.0L

 

Don't waste your time on that Kit
It comes with no tuning that alone is worth 500
And if your willing to Drive to Las vegas Seth can do the install and dyno tune i'm sure
these two kits the STS and CM kit are apples to oranges
The CM kit is built by people who know ls1's inside and out do you think STS does ?
With AWD I think your truck would be a monster

Sorry about taking over the thread
