Prochargers dont start working well until they are spun over their "max rpm", its only over that arbitrary max when you are at peak RPM which is a tiny percent of the time. It also makes the whole powerband better spinning it faster.
this is the tubular crashbar, https://www.glanzerperformance.com/c...eservoir-mount

The 2 core procharger IC is only rated for like 550hp, it's pretty awful.

Not on E. Pump gas absolutely.

maybe I misunderstood him in just the fact that having a cooler denser air charge would gain HP? Going from 190* IATs to say 110* and with cooler denser air that aline will make a huge diff?

Yes colder air will make more power but that's not why your Dyno graph took a nose dive like SS said.

well i have no idea why it did that then. I spoke with Pat G about a new cam and he said not to change it and then guessed that up top was caused by heat soak. Outside of that I don't have a clue

Its a combination of the blower running out of steam, poor IC, and the LSA heads being untouched. That intake port wing is **** poor, get rid of it!

Agree, I've seen LS3 guys swap to the LSA head for boost and I'm like WTF are you doing?

I have no desire at the moment to pull the heads off and have them machined.....IC will be done sooner than later, it's been so damn hot I haven't even wanted to drive the car recently.

got new IC in, didn't get a chance to test it yet as it started raining. I went with the Treadstone TRV25O, 1500cfm and rated for 1000hp. Fit perfectly where the original ProCharger IC was. Also realized that my IAT's are reading too high at all times. Cold car, 80* garage and key in ignition, IAT's are reading 106* off the bat with car off (should read that garage ambient temp). I threw a new MAF in to see and no change. It is a LS3 MAF setup so my best guess is the scaling wasn't properly adjusted when being tuned. Dropping it off this week for some tune refinement.

I did find that the scaling was way off which was causing elevated IATs.

Car made identical horsepower but was significantly lower on the torque. This was on a mainline pro hub dyno. I want to say the car did pick up power though as the injector duty cycle is about 10% higher. Haven't gotten to drive it yet much and still needs some final street revision which I hope to do tomorrow. ​​
