Everything else has been done before. Hood is a problem but it's not insurmountable and I think it would look kinda cool. I don't see it cooling the compressed air well though.

We are actually referencing their (c38 -91/92) compressor maps. We understand and made it noted that the limits would be topped out in the low to mid 600's. Increasing the volumetric efficiency of the motor is key. Plus guys have made mid 500's on GTM's kit on the smaller C38 - 81 units which is what GTM sold as the stage 2. The Stage 3 C38 - 91/92 was never sold publicly. One of our customers has the only STG 3 kit ever sold by GTM. Even then the C38 - 81 was not pushed to its limits. The limitation came with not having access to pulleys and transparency in their kit. They used cheap parts including their intercooler. We firmly believe the C38 - 91/92 supercharger has the capability to put a solid 550whp and reach into the low to mid 600's maxed out.

For the Vortech it is going to be debatable on which unit we would have to use based on space limitations. However, if we can fit it we are looking toward the V7 trim if it could fit... But there doesnt seem to be much of any interest in this platform.

When it comes down to it we need to focus on efficiency of the kit and the motor. The more efficient we can make both the more power there is to be had. Once we have tested our kit we will put out official numbers and our ratings will be conservative. We only want to sell what we know everyone will make.

You have to use a water to air cooler. Similar to what stillen did in there kit and what whipple does in there kits.

We will see what we can do.

Can you talk a little bit about efficiencies of each option? I want my engine to last for 10+ years and 150,000+ miles. I'm looking to limit TQ to 350 FT/LBS @ the wheels. One of the reasons I would prefer turbo over SC is because with the SC, the engine needs to produce the extra power needed to run the SC, so I give up some extra wear and tear for a given HP target compared to a turbo. I've read differing views on how much power is being robbed, but that would be good info to have when comparing to turbo and even among the available SC options you've listed here.

Id cut my hood in a minute for a roots type supercharger!!!!!

Option 2 as I'm only looking for something in the 500 whp range, but I got not problem cutting my hood for a sweet blower at an affordable price.

looks like Roots Supercharger is making a come back.

Well, let me see if I can answer myself. From Whipple's own page.

BTW, Whipple is not a Roots supercharger, it's a Twin Screw.

Um, let's not start taking about "roots" or "twin screw"
There ALL top mount positive displacement superchargers

*They're* also different. I would not want a Roots type system. I also just voted for the Whipple. I think everyone should read up on the differences, and then vote for the Whipple Twin Screw.

I'm not against the twin screw option and its benefits, but cutting into the hood for clearance cuts out a lot of potential customers. So now you have to buy a new hood or be a redneck and run around with a hole in your hood to fit your supercharger.

I liked the stillen hood for the the 350z when i had their top mount sc. I even left the hood on after I took the sc off and went turbo. Got lots of compliments on it too and stood out from the rest of the Z's, Both visually and audibly. Oh how I miss that sweet sweet formula 1 whine!

New hood or hole in hood are not the best options.

Given the interest we may do both. The twin screw and the rotrex have their advantages.
