Got that right brother!!!! LET HER EAT!!

Glad to be part of the additional power equation.

I think Howard is at the track 2 or 3 times a week, Redline is keeping busy for sure.

Nice work, Nice driving.

Thanks Steve! Funny my name is Stephen LOL!
Thanks for making such a badass product! Your headers are AMAZING!!!
Yes he does and im always there with him LOL!

I'm on these forums way too much lol. When the weather gets nice, I get antsy, I can't help myself.

Your using the 8.66 inch lower crank pulley with the 2.55" supercharger pulley, correct? By looking at the graph, I can't tell what the peak boost is. What is the peak boost?

Also, how much of a difference do you think it would make if you were to use the 8.25" pulley in place of the 8.66" pulley? Would you loose a significant amount of boost/power? Just playing around with the numbers, keeps the supercharger RPM's a little lower.

If you are going with an 8.25" lower and 2.55 upper, don't go to that much trouble with a two pulley swap. Just swap the lower only to a 10" ring. Blower speed is 21,700rpm for the 10" lower and 21,000 rpm for the 8.25/2.55 combo.
Stephen wasn't running the higher boost in this early post (10.95) before he was running 10.40s. He has another graph with his higher hp/tq numbers.

Is there any downside to using a crank pulley that big? I may be thinking too much, but I would guess that there is less parasitic loss using a smaller supercharger pulley then a really big crank pulley.

Supercharger rpm is all that matters as many people use 10" lower rings or smaller 2.38" upper pulleys with no belt slip issues. The good thing with a lower pulley only is the supercharger doesn't have to be removed. You are overthinking the situation as the parasitic loss is inherent in a supercharger because it costs horsepower to turn it no matter what. Innovators west even has a 10.5" lower ring!! Have you seen the pulley combo chart from Lingenfelter?

I always over think the situation

As far as removing the supercharger, I was eventually planning on having the snout ported, which would require removing it anyway. I wanted to do it in stages to keep things interesting. For example, do long tube headers, high flow cats, root-fab intake, lower 8.25" OR 8.66" pulley and tune. Drive that for about a year and enjoy it, then go back and get the upper pulley and blower snout ported, and maybe throttle body also done. Keeps things excited for longer. At least in my mind haha

That sounds like a good plan! Get the 2.55" upper when the supercharger is off and you can dial in a lower. 8.25" lower only is pathetic...at least go 8.66".

Advice taken Biggest thing I've been researching right now is how to battle heat soak on this bad boy. Someone that goes by the name of "mlee" on here was saying that unless the reservoir under the SC can be increased, then a heat exchanger isn't much help.

The size of the brick exchanger under the supercharger is the weak link in the system. That is what mlee is talking about. As I pointed out in that other post, it is crazy expensive to upgrade to the ls9 blower with a slightly larger brick. If you can pump 50% more water through the brick in any period of time that is roughly the same as a larger brick. Water picks up heat so easily you don't really need a bigger brick as much as you need more water under there and the better pump is the answer.

I still would change the isolator bearing in the upper. I think one of the moderators deleted my post over there because I spoke my opinion and it was derogatory regarding the engineering of a spring into the isolator. I owned a CTS-V before my ZL1 and the isolator gave me as many problems as your head gasket....promise.

Thanks for the heads up. I'll probably do the isolator bearing as well when the blower comes off. Is there any noticeable difference between the two when you're behind the wheel?

I was looking at the Magnuson heartbeat which uses the TVS 2300 rotors and probably has better cooling. I'm not sure if I want to drop that kind of coin just yet, but it's nice to have that option. I'm assuming the Lingenfelter pump, a heat exchanger (still have no idea which one is "the best") and reservoir should keep things nice and cool. Well….cooler anyway.

No difference behind the wheel. Unless you want to do a lot of road racing with the supercharger, I would stick with the stock unit. The heartbeat is not a viable upgrade. I don't want to sit here and bash on it but it was engineered to go under the stock corvette hood and it makes a lot of compromises to get the size down. I still believe the stock unit is the best blower you can get for overall efficiency. It can be made to run trouble free to 750whp. It can make more power than that but can't sustain it due to heat. From what you have said about your power goals in your other posts, the stock blower is probably the best blower for you.
