Was the bypass bleeding off pressure?
We think so. The drop in horsepower at around 6100rpm makes that suspect. With torque being so close to HP, also is suspect. We had issues with it in the beginning not closing. We think the diaphragm is hanging up. Its a cheap aluminum housing Chinese made no name bypass. I'm going to probably get the bosch 710n bypass. Same as the 102 but is able to support more boostWas the bypass bleeding off pressure?
No. You think I will only see a 20WHP gain now that I cooled the charge temps and can get a bit aggressive with the tune?I say 450ish. Do you still have the IMRC's ?
I am already pullied down to a 3.12. Im afraid if I go to a 2.87 I will see belt slip. I think stock pulley size is 3.6, so I went down 2Are you planning on upping the boost any?
I guess the dyno run will tell all. My goal is to reach that 500whp mark. Now that I am going in the right direction I am unsure what would be next.The biggest upside to intercooling isn't a huge peak power gain but a consistent reliable source of cooler air. You should be able to ad a degree or two more timing but heat soak will no longer be an issue is the biggest gain imo. In fact I would not be surprised if the power level stayed the same or lowered slightly due to the intercooler pressure drop while using the same pulley combo. I would not consider this a net negative however. On a dyno it might look like a loss but on the street your car was likely pulling timing from being heat soaked which should no longer be an issue.
I think the nearest E85 station is 30-50 miles from me. Thought about that route but I really do not want to go there just yet. I thought about dropping to a 2.87 pulley and see what happens. Use to be a bunch of them for sale but of course when Im looking, they arent out there.E85 and a pulley down to the next size will do the trick for sure.

Never asked about timing. Kinda thought it was a waste to ask with how high my temps were. I think on that day it was an average of 190. I thought about doing a 10% lower, Kinda crazy how much they are. Does anybody have a good deal on a used one? I truly believe if I go to a lower pulley unless I use a grip tech that I will be dealing with possible belt slip. Im not trying to make a 2hr job for myself changing belts every 500 miles.If you are not changing the pulley, the only HP gain will be from adding timing. As you are going to loose PSI with the intercooler, but temps will be better to allow you to add timing. How much timing are you running on the on the 430 HP run? You can add a 10% lower and keep the 3.12 upper and get aggressive with timing to shoot for the 500hp mark.
