Rotrex Supercharger Thoughts?

With antilag devices you can run larger turbos w/o the lag almost instant boost. With VNT tubos depending on the internal geometry can make up to 10psi @1000rpm. Centerfugals are ok but who wants to hit maximum boost @ redline. Roots and lysholm (twin screws) work great, sound very cool, and are an excellent choose for street or Auto-x due to excellent low and mid torque but who really want the parasitic drag. Turbos FTW best all around power with minimal losses & drivers adjustable boost control( no pullies to change or extra software and injectors to turn it up. As for track use I would preffer tubo. Or NA with lots of money for instant respose good for all around everything but@ 2+x's the cost. $.02

^ Yup. A turbo utilizes wasted energy to create a more efficient combustion cycle, a supercharger does not.

Yeah, but the properly sized road-racing turbo won't make any more power than a supercharger, so the supercharger is still a bit better as the lag is still slightly better. I'd say it comes down to cost and availability at that point.

I fyou compare a same engine, with both system runign almost the same boost and rest of avriables (assuming both has properly sized s/c and turbo for the HP goals) turbo will EAT alive the s/c setup...it is more eficient system.

That's been prooven.

turbo supercharger were used widely in the aviation industry. now days, i'm not so sure but if you do a search on turbo superchargers, you'll find enough information to fulfill your wishes.

thier are turbo supercharge cars out thier. i know that thier is a kit for a scion tc makes around 500hp but front wheel drive cars are lame the car was all so in super streets last issue.

[philip1]

a properly sized road race turbo has adjustable boost and therefore adjustable power levels. how do you adjust the power level on a supercharged car while going 150mph?

[Insanity]

for those who say a supercharger is vastly supirior in road racing i dont think that is completely accurate. a properly sized turbo on a road race car will do just fine, make plenty of power and not have horrible amounts of lag.

I saw a R33 skyline with a roots supercharger remotely mounted, in addition to twin turbos. No idea how it performs, though.

I have seen a picture os a R33 with a roost blower mounted below the blow/nexto to the block and two turbos mounted...I guess the blower was just for low end torque or response...twins will do the job in the high rpms when they are demanding maximum power for serious speed it's my guess!

I have seen also a Subi Impreza with two turbos and one roots s/c mounted next ot them.

haha really? any pics or vids?

[boom-monkey]

im going to put both a turbo and a supercharger on an engine somehow then watch everything break when i turn it on...
That will show you basterds. haah

It's been done.

Desing, hmm I wouldn't say that at all...see the size of the compressor wheel in the S/C and compare it to a mid size turbo wich you will notice is smaller, yet will make more power and torque... S/C is for ladies IMO. I own both systems and I know what I say.

c ya!:D

A centrifugal supercharger and a turbo pushing the same CFM will make the same power. The parasitic losses of the supercharger are easily made up by the non-restricted exhaust.

Also, you may "know what you say", but you certainly don't know what you're talking about. Superchargers are infinitely superior to turbos for track racing.
