S.C. high rpm's
 

Just wondering, Would a supercharger be ok if you were to have a redline close to 9,000 rpms

These cars have oiling problems at high rpms, what are you going to do about that?

Dry sump would be needed forsure and even then I don't think you will be able to spin it up to 9k safely.

I would think it would be cheaper and safer to just buy a kit that offers the HP you want with a normal redline.

Also have to remember that as you increase the engine RPM you are spinning the SC unit higher/faster.
I know with GTMs kit that at around 7500 RPM (factory set) you are at the max limit of spinning most rotrex units, especially once you drop below the 90mm pulley size. So pushing the engine RPM up will put you out of spec for the SC and overspinning gives you no benefit other than killing the SC faster.

This is strictly speaking for the rotrex units, stillen's kit (vortech) might different but I imagine it has limitations as well but it might have a higher threshold.

Yes I would have a dry sump if I were to rev that high. I got the answer I was looking for about the sc being out of spec. I'm going back and forth about boost or buying a dry sump and going for big power NA.

What's with this recent craze for high red-lines?

Wanting to see how far the VQ motor can be pushed, we all know it can handling boost like a king. For people wanting to keep it NA and make decent power has been my quest. Just trying to way out the options on spending 6K on a dry sump or 6K on a SC kit

Are you going to be at sebring april 12?

Who is there April 12th? As of now I plan to be there March 28th (Chin), May 2nd & 3rd(NASA),June 21st & 22nd (NASA), August 22nd (PDG) and October 3rd & 4th(NASA) this year but would love to add more. I'm going to Homestead tomorrow night.

April 12th is chin motorsports. I won't be running my car as it isn't nearly set up to be ran on the track, my buddy is taking his Z06 vette and i'll be riding with him. I'd like to check out your set up.

I've already paid for the May NASA event so that is probably to close together for me. If you go to any other events with him let me know, if I'm at the track I will gladly take you out in the car.

cheers!

I was close to 8000 rpm .... I was.......


This was one of the problems that made me for almost 6 months pass without my "Z" :icon08:
