So I've been doing a little looking around and stumbled on the ARK RSpec Res TP.. does the Helmholtz Chamber make a world of different in terms of back pressure? Or again is this is just negligible and left all to preference..

I finally have some time for a proper reply. So to give you a straight answer; for $15,000, it is not worth getting the twin supercharged system. I got it for $10k installed. For that price, it was worth trying. When I first drove it, the thing was an animal. After a month of having it home, it just never made that kind of power anymore. Two tensioner pulleys broke, the stock tensioner pulley broke, belts shredded, and it squealed. I do believe those issues could be fixed, but I was tired of dragging it from place to place trying to get it to run right. I plugged in a basic boost gauge under the hood to see what it was making, somehow it went from 12lbs to only 4. I took it to a shop and asked them to check the BPV's, and they had found they were completely loose, essentially bleeding boost out. After tightening them, it did gain a lot back, but it was in desperate need of a retune. I started getting nervous with all the small issues cropping up, so I cashed her in for $33,000 and started fresh.

So the pros with the kit...
I do believe this kit can easily make 650+whp with 84mm pulleys and a built motor.
It looks seriously awesome under the hood.
The power was very linear and got faster the higher you revved the thing.
It sounded wicked and long tubes fit with the kit.

The bad...
The pulley issue
The squealing
Can still make more power with a turbo
A lot of moving parts
The 3" intakes neck down going through the core support
It was made by GTM and their support was not the best.

Thanks for your input. Sounds like it can take a turn for the worst very quickly.
