Ahh, I gotcha.

I got my nGauge and the gauge pod for my Lamdba installed and ready. Pro Charger is supposed to be here anytime starting tomorrow!

My unicorn Pro Charger finally arrived! I can't get to it for a few days but at least it's finally here! Stage 2 intercooler and a 3.7 pulley.

3.7 pulley 0.0! Are you upgrading fuel? Im definately going to check up on your build! Should be installing mine next week, fingers crossed!

You got it! I'm trying that pulley also. No cam but fuel upgrades.

The only fuel upgrade I have is the raised fuel lobe on my cam, but with the cam, long tubes, and better flowing larger exhaust it won't make as much boost as it would on a stock set up.

How is yours coming along?

Um, it's not how much boost your gauge reads that determines how much fuel you're burning, it's how much power you're making. Starting out in the upper 400s for rwhp, then adding the amount of air the supercharger is going to push with such a small pulley, is more than the stock lpfp is likely to handle.

An how does boost relate to power?? The guys at pro charger and my tuner have my spec and that is the pulley pro charger recommended with my spec.. not me. Everyone in this forum is so stuck on "X" power means you need the LT4 fuel system and when every LT1 will run out of fuel is static. It's all relative.. I agree though, it's very possible I could need more fuel. Especially given the LT4 stock cam has an increased fuel lobe and .2mm larger pump. We will see how it goes. I don't have much faith in the amount of extra output the LT4 pump has in comparison to the LT1.

Are you talking about the hpfp? Because you've increased the travel with your cam lobe so for that pump I'd agree, test it and see. What I think would be smart though, is increasing the low pressure supply. The hpfp is only as good as it's supply, and the amount of power you're likely to make with that 3.7 pulley and cam/headers is more than anyone has reported a stock LT1 lpfp handling.

Oh, I agree 100% on the LPFP. That is my area of concern for sure. It provides all the volume for that system. I'm wanting to see how it does, and will guy whatever I need I'm very familiar with DI engines and how it works. That's why I cring at all these people doing the high side first.

almost there!
