Default H/C vs. LPE Super charger -

Been talking with LPE about a H/C package. How about some feedback on whether you'd go with a H/C package or their Super Charger?

The LPE supercharger probably if you'll be content with what it gives you. If you would like the option of spraying or supercharging for even more power later on go with the H/C. Both give awesome power, but the S/C is better for a daily driver. :cheers:

I'd have to give the nod to the LPE-Blower :) :yesnod: It seems to be the pocket rocket. Check C5 General for a video of a dude doing a flyby! All you hear is the supercharger screaming!!! It's :cool:

Thanks for helping me out there ;)

I must have watched that 20 times so far :D. That's all you hear is that supercharger whining! It sounds angry :lol: I like it :D:D:D

The answer to your question depends on the use you plan for the car. If drag racing and hot street use are the plan, the SC is a good way to go. If you plan to go to a road course, the head and cam will not suffer from heat related hp loss as much as the SC will. Good luck! :cheers:

Awesome video. I would probably go with the SC. For something tried and true, I'd recommend the head/cam.

I was stuck for a while too. I decided on the H/C because of the option to spray for REALLY fast 1/4 times. Plus the huge wait on the LPE S/C didnt help, AND I don't like the hood.

You don't need both, the S/C improves the V.E. (volumetric eff.) w/o the H/C pkg. Prior to the S/C, the best (IMHO) way to improve the V.E. was a H/C, exhaust, intake, etc., however, w/ the S/C pressurizing the air charge (vast improvement over normally aspirated, 14.7psia vs. 20.2psia or 5.5 psig). The H/C pkg., if added after the S/C, would not show the same power increase as it would if installed prior to the S/C. I did the H/C before the S/C was availble, but I want the torque curve the S/C offers so I'm doing the S/C. There, are you as confused as I am now. :cheers:

Just something to think about... If someone plans on selling the vette within a few years, which vehicle is worth more in value? A heads/cam setup or a supercharger install??? Inquiry minds need to know...

Actually Steve I am going to have to disagree with you here.

I understand the physics side of things, but from a practical application that isn't the case.

There are plenty of cars (Supercharged Mustangs) which is where this has been seen a lot.

The move to a better set of cylinder heads actually shows a bigger improvement on a car with a supercharger than on a N/A car.

I am not saying that I have tested this on a LSx platform, but remember, boost is a measure of restriction. Remeber from the GN/TTA days. You could throw a set of ported heads on a car run less boos and make the same power. Turn the boost to the same pressure (PSI) and the car was faster. Why, more air and fuel = more power.

Go with the S/C. Nothing like looking under the hood of any car and have a blower staring back at you! This will be my next mod the first of the year. :cheers:

You could throw a set of ported heads on a car run less boos and make the same power. Turn the boost to the same pressure (PSI) and the car was faster. Why, more air and fuel = more power.
I was drawing from my experience w/ my 89TTA. I installed a set of ported,polished, bigger intake valve heads and didn't get that big of an improvement as a N.A. motor would've. I asked several "guru" types and they explained what I originally posted.
Basically, I'm trying to show that since the S/C mod doesn't have an intercooler, the max boost is ~6psi, going to an overdrive pulley will probably cause detonation probs.
I think since the boost isn't as adjustable as the GN's, the HP gains w/ a H/C mod aren't as noticeable w/ the S/C pkg. Example, if a H/C mod gains ~50 rwhp and a S/C mod gains ~ 100rwhp, the total rwhp gain for both will not equal 150 rwhp. Since both pkgs. cost about the same, I'd take the 100 rwhp first rather than the 50 rwhp.
As usual, dissenting views are always welcome.

I think I can attest, H/C is NOT necessarily "tried and true". ;) :cheers:
