Ok, turbos give you the boost at the end of the rpm range and superchargers give boost troughtout correct? SCs cost so damn much are there turbos for our 3.9Ls? If so are they cheaper? I need some serous power here, but not enough to pay 3 grand.

Turbo systems actually cost more than a S/C.
We're working on a single Turbo system for the 4.7L at the moment (Liqued intercooled) and then over to the 3.9/5.2/5.9L (5.2/5.9L will be a twin turbo and the 3.9L will be using a Hybrid).

well saying that turbos give you boost only at high rpms isn't quite accurate. people talk about turbo lag as a big problem, but they don't realize that it's all relative to the turbo size. a mistubishi VR4 with the stock 9b turbos will reach full boost(11.5psi for 2nd gen)by 3500rpms with only 3.0 litres of displacement. while on the same block with a N/A engine a supercharger doesn't make full boost(usually about 7psi with the stock compression ratio) until redline, 7200rpms. a supercharger's amount of boost is directly related to the engines rpms., and will only make it's full boost(according to the size of the pulley that you use) at redline. obviously with a bigger turbo you'll have lag, but you also will have the option of turning up the boost higher and holding more boost to redline.
anyhow, xphile, if you're looking for LOTS of power i'd go with a fairly large turbo and lower compression ratio pistons and just turn the boost way up. however, that's gonna cost you a butt load of money. custom manifolds/downpipe/intake, plus the internals and all the work to do it. a supercharger is prolly your best bet. it's a direct bolt-on and can be done in a weekend with somewhat limmited know-how. bernds boosting 10psi i believe with stock internals. 10psi is alot of HP, so i'm sure you'll be happy with your gains.

Toxic, The VR4 (and Spyder) also use twin turbos with the primary unit spooling up quicker than the second. This makes for excellent broad range boost without any lag on bottom end.

My question is who makes a supercharger for the 3.9 v6, and how do I get into contact with them. Bern I see that you are running a supercharger 3.9, where did you get it from, and was it a modified supercharger for a v8. Also is it cetrafuge or twin screw?
Thanx in advance

actually bernd the stealth/VR4's turbos spool at the same time. they are NOT sequential(they're both the same size turbo, mitsu 9b's in a TD04 housing). however the Supra (inline 3.0l) twin turbos are sequential with the smaller turbo spooling first, and then the larger more powerful turbo takes over.
you can never really say for a fact that turbo's are better than superchargers, or the other way around. it all depends on what you're looking for. also, there's alot to know about turbo's and alot oc different options to choose from when adding a turbo to your n/a vehicle(different housing sizes, different turbine wheel sizes, cfm rating, etc. etc.). just make sure you research your options well and get what you REALLY want. because either way, it's a fairly big investment to end up only "sorta" happy with.
btw Bernd, nice new time, glad to see you got back to the track and broke into the 14's. and good luck getting those turbo kits on the shelf.

Oops...my bad, you're correct. (Got the ricers mixed up.) ;)
Efficiency wise, the Turbo is better...heat wise, the Supercharger is slightly better. Cost wise...well, that depends on the S/C or Turbo kit.
We've been working with several Turbo manufacturers and intercooler companies as well. This project was on the drawing board since May 2001 and we've finally got it down to the actual plans (fuel system included). Once the local shop is secured, we've got a 4.7L coming our way (for 3 weeks) for the proto-type, testing, and final build phase. (Whew)
We'll have all the details on the website once this is completed.

11#. Anything higher and the impeller bearings will fail. (Mustang people used to do this a lot and gave Powerdyne a bad rap because of it.)

Has anybody here tried to figure out their fuel mileage? I'm considering a s/c'd 97 5.2 over my current carburated 400c.i for my 74 newport. I figure small truck specs would be close to my boats! thanks
