(A few overlayed, best run in bright green cut short )
*This was copied from the Cobalt build but all of it will apply to any car, we offer "stealth" Turbo Kits for almost any car!*
This is built on a 09 Cobalt SS - Turbo. We could easily offer the same setup for either XRS or XR Matrix/Vibes. These new Turbo's are incredible. The give you great low end response like a smaller turbo with no drop in top end power like a larger turbo. It also has a integrated External WG style Internal WG along with a built in Bypass Valve! No need to buy and plumb a EWG or BOV, it's all right there
My impressions of our kit:
When you pop the hood it looks like nothing is done! In fact, you have to really look to see if it's even a turbo car. That part of it I love! All of the other cars we have made Turbo Kits for in the past were the same way. So, that was our main goal when making this kit. The CP from the turbo to the FMIC (what we would normally call Upper CP on SS/TC's) is routed under the engine and is NOT the lowest point on the car. The donor car was quite low and we have yet to hit that pipe on anything!
First startup with the kit on, you can hear an immediate difference in the exhaust note. It sounds much deeper then stock and just plain sounds sick when WOT! With the base map loaded we took the car out for a first drive. I was expecting a little bit of lag but in reality it drives very similar to stock, VERY responsive at any RPM in any gear! (again, comparing to stock SS/TC) In fact, the spool-up is almost identical making the car great for around town or Daily Driving. When you look at the Dyno Graphs posted below you will see it performs very similar to the stock turbo low end Torque wise. The big difference is the additional 70-80 whp up top. The car pulls hard right away and doesn't quit until you shift!
Last night we took the car to the dyno to run the new kit. I was feeling like it was around 380whp on the butt dyno. Sure enough, the first pull it did 390whp at 24psi. We tried several scenarios on the dyno, all netting similar results. Little more boost, the car knocked up top with similar to stock peak timing. Dropped it down just a tiny bit and tried a little more timing, similar results. The best run of the night it popped off a coupler mid pull You will see in the graph it was on it's way to being the best run of the night. All of the pulls were between 380-400whp and 380-400wtq as well. He is only running Pump Gas for right now, and without Meth. So as we kept adjusting the car we saw immediately this was a limiting factor. Jason also needed his car back and we decided to just leave it there and play is safe for now. We plan on running his car with E85 to bump those numbers up around 450whp!!!
