TURBOCHARGE or SUPERCHARGED - The $64 Question

[AL427SBF]

olddog, didn't say "... an absolute fact in all circumstances", far from it - but you don't run top fuel on the street, we're talking a car that you can enjoy on the weekends and register with the DMV. I would still go torbo if I were building the motor from scratch, but I've changed my mind with an already built engine. Easier to jump to a supercharger, but I would go with a twin screw from Kenne Bell or Whipple, more efficient than a roots. I'm betting my "normally-aspirated engine" is built to do the job and I won't need to do anything.

How about a little NOS??

It's by far the simplist and cheapest way to get HP. The really great thing... If you don't like the power all you have to do is take it off. You also can keep your 10 or 11 to 1 compression, unlike a proper designed supercharged or turbo system. I'm thinking of a 100% hidden 300hp progressive fogger system in my 482" aluminum sideoiler for a winter project. the whole system will run me about a grand and I can adjust the power to come on a any rate and go (up to 300HP) as high as I can safely handle.


Oh, btw... drag radials will become pretty much a requirement.

If it's a twin screw it is a Roots style blower regardless of the marketing hype. I had one on our last Toyota Tacoma and am about to put one on our new one. From a simplicity and bang for the buck point of view I don't think that it can be beat.

Agree, I think you can consider a twin screw a perfected roots system.
