I wish we would have crossed pathes a few months back.
To answer your question I'm not sure about the inlet air temp.
Believe it or not we've had a rather cold winter here in Atlanta with a hugh ice storm just this last weekend. My project orginally included an air-to-air intercooler in the fender just in front of the pass side tire. The piping to and from the intercooler was a mess and I was lossing boost with all the turns so I took it off after a couple weeks. The performance inproved and I have had no hot inlet issues (yet). Once summer arrives I'll re-look at the intercooler idea and probably consider a small air-water unit.
Now a couple questions for you:
On the intake runners you have a boost gauge installed; what device was in that location before?
Have you made any changes to the ECU/ Fuel delivery system to handle the increase in air flow? If so what changes?
Thanks!

Hi!!
Finaly someone that has done "the samething" to he's engine
Nice to share experience with someone.
On the intake runners/plenum there were a device that separates the plenum. It crates a longer runner if you know what I meen. Long runners creates more tourq at low engine revs. And this "device" keep them separated intill the engine comes over 3600rpm's, then it opens the plenum so the runners become just as long as you can see on the picture (from the boost gauge and in to the enginehead.)
This happens at the same time as the intake cam turns 8 degrees.
I have mounted a computer controlled ignition og fuel system, it's name is electromotive TEC II. View

for details.
Becouse I haven't had the opertunity to test my car, I still have the originale fuelpump. But I'm unsoure this pump will give the flow required...
Injectors are replaced with Bosch's 440cc. And the enginehead are modified so the compression ratio are now 9,54:1 insted of 10,5:1 (org.)
