What you see in the above graph is my setup that I have been runing this year (APS) through the 4L80e with a peak power of 925rwhp compared against the new setup (IPS Twin Turbo) through the 4L80e with a peak power of 1072!
So, in short... I WAS running 9.04@157 on the old setup...
Results from the new setup comming to a track near me soon!
Lots and lots of time and R&D went into the improvements you see in the graph above and we are very pleased with the results from our prototype kit. We were hoping for bigger numbers but with the converter un-locked and with the 4L80 robbing as much power as it does we are still quite happy with the gains over the old APS set-up. I think we had 5 or 6 pulls all over 1100rwhp which isn't bad at all.
I would love to see what this set-up would make through a 6-speed
Track times to come soon and I can't wait to see what this car makes on the big-end now

Very nice #'s!!! What turbos? Still running similar turbo placement to aps?
The turbos are still in the same general area as with the APS kit (Not a rear-mount kit or anything). The turbos out-flow the APS 35Rs at bigger boost levels and yet still offer great low-end response as well.

that is bad ass, how has the 4L80 treated you? any failures?
The tran's has been great! I didn't brace it when I put it in at first and seperated the rear from the trans on a lauch once. That caused some issues but the internals were fine.
For big power applications (over 800rwhp) I would recommend the RPMtransmissions 4L80e. Under 800rwhp I would use the more effecient and lighter 4L60e.
