For the self-initiated, the valve in the Pettit Kit is the Bosch #0280142102. This valve is used in many German/Euro applications and one of the first things these owners do is replace them with a billet upgrade. There are several sources available;

My 2001 Kawasaki ZX12R Radiator turn into a SC Intercooler Heat Exchanger Project
Take a look at my second project of the day…Sweeeeet!
Total cost $52 for the radiator and total with materials @ $75

The biggest difference (my son pointed it out) is that my engine temps are a whole lot lower and they crazy drop down after a session of drive it like you stole it mode. Keep in mind that my car has a BHR radiator. I think that the old SC Heat Exchanger was considerably reducing the airflow to the radiator.
Take a look at the video my son took (sorry no sound) while driving from 0 to 132 MPH. Pay attention to the boost (8.3), the steady climb of the IAT and Engine Temp.

Airflow through the rad is everything.
I just yanked my Koyo out and put the OE rad back in and saw a dramatic drop in coolant temps.
Your ambient temps are still too low for a real test - especially with that east-coast humidity.
I'll be interested to see the results when your ambient temps are in the upper 90's.
As far as IATs go, that is still high for an intercooled setup at speed, though not unexpected because of the blower outlet temps and the A/W saturation rate.

Juan. Are you going to try some of the springs with your new valve?? As you allready know, Phil is reporting 13-14lbs. I'm excited(and I hope others are also) to possibly learn this is reproducible by simply changing the valve.

It’s that all? To me it equates to taking my wife out for dinner at Taco Smell and giving her gumball machine jewelry. How about adding a BHRs Heat Exchanger upgrade, SC Pulley Kit upgrade and to top it off a BHR Radiator. Now THAT will make her real happy plus mega points for an upcoming night with the guys at the local strip joint. Needless to say you will be waking up in the morning a much happier man.

I talked to Cam and he explained to me that the reason for not loading a spring is to led some of the compressed air bleed back into the blower while cruising thus keeping the engine temps down, compressor noise down and it also saves fuel. Once you step on the gas the valve shuts immediately regardless if you have as spring installed or not.

substained high speed driving is the real test here --not a sprint .Although very useful and good info you really need to get on track to verify the cooling capacity while you have good air flow. City driving is another story.
Juan have you upgraded the water pump? It does make a difference. The coolant temps are not in range with really hard driving--you need to be at about 210f for that.
All this is without the w/m system---right?
Curious ---what is too high intake temp? What range are we speaking off and why?
oh by the way just picked up a turboxs bypass valve(bosch replacement type) at Summit---i had coupons!!! To install along with a new fuel pump tonight. new fuel pump just for the hell of it.
