What is the stock boost for a Comptech Supercharger? Are there different variations of boost with a Comptech Supercharger?

Any downsides to Comptech Supercharger......

The older Comptech was a whipple unit and was offered with a high boost pulley, around 9-10 psi I believe but that requires a stand alone engine management. The standard boost Comptech is 6-7 psi, and uses a boost-a-pump to double voltage on the fuel pump which gets more fuel through the factory injectors to cover the 6-7 psi of boost. It is not perfect in terms of Air/fuel ratio, but it is fairly accurate and it tends to error on the rich safe side, not the lean dangerous side. It's a pretty proven system, some cars have had them on 75k miles plus, and many are tracked. The newer "autorotor" supercharger runs slightly cooler and develops 5-10 more HP. I have not seen a high boost pulley on it. If it is the standard Comptech, it's probably the low boost and that is 6-7 psi. It is the simplest system out there, the only one that is 50 state legal, and CARB certified.
cant wait till i get one in the future. i miss my s/c i had in my CL.

The Whipple takes about 10% HP just to turn as the turbo does not. Say, you're pushing 500HP, it's taking about 50HP just to turn it.
I prefer the more efficient tire shredding characteristics of a turbo. :biggrin:
I think your close.
Whipple low boost is 6lbs. High boost was 8 psi.
Auto rotor was 7 psi. Not sure on high boost.. Probably 9.
The auto rotor was making about 20 rwhp because it flowed more air and was ~1 psi more.
Lighter wallet. Tapped out credit card limit. And desire for more hp on your other vehicles to have comparable driving experience. I had to upgrade my fleet of vehicles to keep up with the NSX.
what about low boost with the rdx injectors would that run better
What do you mean by run better? Make more power? It runs great as is.
i mean would that be a better option then the factory injectors
i keep hearing about the rdx injectors lol

A downside would be supercharger whine if you don't like the way it sounds. For me it ruins the driving experience completely despite the added power and reliability. I truly envy those who are content with it bc of its practical advantages, but IMO NA cars are way more fun even if they're slower (and expensive to build) and turbo cars are more fun too (at the expense of complexity and added risk). It's all a balancing act so as long as you are informed you can make the choice that's right for you.

Actually, I wouldn't be surprised if it took closer to 80-100hp based on estimates from other cars i've seen :frown:. I still prefer the SC in most cases. If you're a mostly straighline racer guy I would like the Turbo. Being that I prefer road racing it's too much trouble (or i'm just not good enough) to keep the gas pedal down to keep the engine in boost. SC = Boost all the time but turbos are way more efficient if sized properly. That's a big IF.
That's been my plan - CTSC, I/H/E, RDX injectors, AEM FPR @ 58psi, Walbro 255, AEM F/IC
Just need to find time to do the install and tune. We'll see...
ewwww.....sounds like fun.........:biggrin:

thats my overall goal also. got I/H/E already, doing rdx injectors this summer.
why is that?
Because it's. Bigger. I was making 430rwhp on pump at just under 10psi.
CTSC seems to be safer from what I hear.
You would have to ask prospeed about that. I am not sure how the RDX injectors will work with a base CTSC system. Since it is a very simple system, I am not sure how it will respond to a reflashed ECU and if it will properly compensate to get the correct A/F.
Many people use aftermarket injectors when they go to High-Boost and can properly tune it with an FIC. I think the original high-boost kits came with prelude injectors. Still old tech.

Because the cost is very similar and the SOS makes more power. The SOS is just a Kenny Bell blower. Its bigger than the CT unit and make more power.
Yes its safer as I'm sure Batmans understands well. :wink:
But most of us in California use the CTSC because its CARB legal.
Agreed. Some day I hope to do the CTSC for safety and CARB. I know power is addictive, but things reach a point of diminishing returns and I'm sure 350HP is more than enough to get me into trouble.
wow so the sos blower puts out about a 100 more hp for the same price of the ctsc. im thinking ill probably do the the ctsc since i have an auto to be on the safe side, but that extra 100hp is tempting.
No it's not the same price and it's not the same thing at all. That extra power comes from an intercooler and heat exchanger and aftermarket engine management, different pump, injectors, tuning.
The CTSC uses factory engine management, and has many fewer parts. It is much simpler in design. SOS systems use aem ems's or aem FIC's and to get the extra power you buy the optional laminova cooler which requires a water pump, lines, and heat exchanger.
To go beyond the CTSC's power level you really need a significantly more complex system. All this info is already available on many many long threads on prime.
