New turbo set up! Group buy
Cheers

Edit: I have the car here just south of Pembroke if you would like to come for a rip >:]

IC is the only way to go then...
Any word on gas mileage with the kits?
But if you have a heavy foot and you're into boost all the time, Dont expect it to be wonderful

Don't forget that you are not seeing an improvement due to the intercooler. It is due to the ability to run more boost with one. The non-IC graph appears to out perform the IC graph as would be expected at low boost numbers due to pressure drop across the intercooler and the earlier onset of meth/water injection. A little back of the envelope math tells me that a 5 PSIG increase in pressure is going to add (roughly) between 40F and 50F to intake temps from ambient (between ambient of 10F to 115F) BEFORE the m/w injection which would drop the temps considerably and it was not a huge temp increase to begin with.
You would put more power down to the ground below 4600 RPM or so with the non-IC kit. I don't think you are going to see much difference on the street due to not being able to put all the power to the ground of either kit at lower speeds (both would vaporize your rubber at any RPM in first gear @WOT) and the power advantage of the IC/higher boost would require you to get above that 4600 RPM or so in second gear (over 80 MPH before you got any improvement in output and then you might be playing catch-up) I think the non-IC kit is the way to go in a street car (the way I use it) and that is not even considering the substantial difference in costs for the full kit. Now if you wanna build a top-end track car, push more than that 5 PSIG of boost, or do the half-mile street racing thing, then sure, IC/more boost is a no-brainer. I just don't believe that a primarily street driven (front drive LS4) car can really use that much power.

Sooooo price on the intercooler and everything else to upgrade?
