Questions about vortech tuner kit
Considering the vortech tuner kit and assuming I already have an EMS I have a couple questions...
Do I need an aftermarket adjustable fuel pressure regulator? I've read a number of posts that indicated the stock regulator is fine, is this true? Will the stock regulator increase fp with boost? Do most tuners prefer to tune with stable fp or fp referenced to boost?
It looks as though the vortech complete kit does not come with injectors. I assumed I would need larger injectors. What size would be recommended for 7-12 psi?
I intend to run the tuner kit + ems + walbro 255 + ~650cc/hr injectors with the UR air/air fmic... missing anything?

I bought the V3 tuner kit but my car is on flashpro so it didn't come with the FPR option(can't comment).
I would suggest getting ID1000 injectors since the (ID)750cc and 1000cc are the same price. Currently tuned on the stock 8psi pulley and already at 64% duty cycle on the ID1000's.
Stay with the air to water aftercooler/heat exchanger the kit comes with.

Lol...What you don't realize is that Vortech's base kit already comes with the bigger heat exchanger that SOS offers as an upgrade. Pretty sure you'll be alright since air to water is just as good(if not better) of a means of cooling than air to air. If you want more cooling then upgrade your radiator to the FBM aluminum Rad with the slim fans.

It's a track car so it's going to be difficult to cool.
I'm afraid it would heat soak even with the larger heat exchanger from SOS, hence the air/air fmic.

Problem with water to air once the heat exchanger gets heat soaked it is much harder to cool it back down. For normal driving the water to air is much better for a supercharger as it is harder to heat soak. But once soaked harder to cool down.
You will lose 3-4 psi probably with the fmic. So you will have to run a tiny pulley if looking to run 10-12 psi. On an AP1 the 4" pulley makes 12.5 psi. Since you would be running the fmic you would need to run the 15+ psi pulley to get that most likely which will be moving a bunch of hot air up there. If aiming for 10 psi you should be ok.
As mentioned above I would definitely go with the Injector dynamic 1000cc injectors. No need for a fpr. That is what is used when you don't have a stand alone ecu to tune with.

Yes, I have. Once in the dry and once in the wet. :-)
And I have a buddy that tracked his '00 ap1 with the upgraded V2 kit pushing 14psi(400+ whp) as well w/o issues.

They were evening/night sessions. Ambient temps were around 50-60 degrees. I did not log oil temps, The few times I glanced the oil temp did not go past 245 degrees. Did not look into IAT's or Water temp. Car didn't show signs of fatigue or overheating. Only mishap was losing the BOV filter somewhere on the track during one of my sessions.
