Thanks!
But is there any benefits of buying more expensive Procharger red race valve?

My goal is about 400hp using P600b. Now I have 330hp.

Here is the current situation...I need first build my head unit...

You might hit 400HP with the P-600B. It seems tough to imagine that you are at 330WHP currently, but if so that is great.


There is no benefit (for your power levels) to go to the Procharger red top BOV.

Ok. Thanks!
I have dyno tested...

I have now:
-113 Corvette heads
-1.6 rockers by scorppions
-mild cam by comp cams with 550 lift
-ported SLP runners and plenium
-34lb EV14 injectors
-Hedman headers
-2,5" exhaust no cats
-tuned orginal PCM

Next coming:
-rebuild P600b with billet D1SC impeller
-Aquamist methanol/water injection

Let see how I can get all those working in future...

You do have a few things in your benefit over factory. Good luck with the build.


BTW, I ran a P-600B for several years prior to moving to the D-1, and later R-series. That P-600B has the loudest "whine" of any blower I have worked around (not a huge fan). Straight cut gears tend to do that.

Hi,
Next I should find a good fuel pump for my setup.
I want a new one to be compatible to E85 for the future. And it must be in the tank installation.

What you think about this Racetronix system?

What do you recommend?

That 255L/hr pump would likely work fine. I run a big Weldon external on mine.

Also I will install Aquamist HFS3 methanol / water injection system. I am planning to use 50/50% water and alcohol.
I have also all electrical gauges which needed. (fuel, boost and AFR wideband)

Next, I need help to choose right valve to my supercharger.

Is the Procharger red race valve right one?
Or the Procharger surge valve?

Thanks,
Hi again,

I decided to buy TIAL Q 50mm blow off valve. But what's the difference those different psi models?
Is the right model that - 2 PSI Supercharger valve or higher PSI model?
