Supercharger vs. Turbo

[duplox]

Not one t3, two.. I'm running two .60/.63 T3's on my 351. I got the recommendation for these turbos from the site www.toohighpsi.com. They were used on his Budget TT 351w.

i have not read this whole thread.
i was just wondering if sequential turbocharching has been mentioned.

[duplox]

Don't think so.. Do you mean sequential as in one turbo for low RPM, one for high, or sequential as one turbo feeding another to achieve rediculous boost levels(ie two turbos, both compressing at a 2:1 ratio, one feeding the other... that gets you around 44psi... one turbo at 2:1 gives you 14.7.) If it is the first, its not an easy thing to do. The exhaust piping will get VERY large and complicated, not to mention expensive for all the valves you'd need. Something best left for the pro's... As for the second, you better have some very good gas(propane, nitro, toluene...) and a motor that is VERY good at getting rid of heat to withstand that kind of boost.. as well as a very low comp ratio! Not to mention the shortblock that would be required, and the extremely hot spark to get through all that air... Again, best left to the pros. It'd have no place on the streets anyways, who needs a 302/351/4.6 thats running 40psi on the street? That'd probably put you in the 2000hp range... Sweet.

I'd love to have that kind of horsepower in a streetcar it would be the greatest ever made.

The fastest street legal cars in the US run 6 second 1/4 miles... thats right around 2000hp!

Here's a question then:

Where would someone look for turbos on the 4v 4.6 Cobra engine(97)?

[Got Torque?]

correct me if im wrong, but 03 cobras and lightnings have EATON superchargers not WHIPPLE. there is a an upgrade kit from whipple for the cobras though. (im hoping there will be a kit for the 5.0s) as for the turbo or supercharger, if you want a street car, i would opt for the supercharger (i would prefer a kenne bell twin screw) (www.kennebell.net) but if you want a full out race stang i would definitely go for a huge turbo. they are much more better for making power and gobs of torque, but with the heat they create i wouldnt want one on the street for my mustang. just my opinion though.

On further research, yes the superchargers are made by eaton.. The Ford website says 'Roots type' for the cobras, but it says 'Lysholm Type' for the GT, which must be where I heard it from, and my poor memory kinda blurred it all together.

[Got Torque?]

yeah, i used to think there was a roots on the gt but my friend told me a few weeks ago that it wasnt. is Lyhsolm the brand of the s/c? cause ive never heard of a lyhsolm "type". from what i hear the brand IS actually whipple. not saying your wrong, i just want to know

[duplox]

I beleive it is referred to as both a screw type and lysholm type... I believe someone named Lysholm invented it, much like a rotary engine is known both as "Rotary" and "Wankel". Whipple is just a brand, but they're the big manufacturer for lysholm/screw types, so some people just refer to them as whipple superchargers. Lysholm Technologies is a brand though - although I'm not sure if they distribute to the US. Their website is http://www.lysholm.se/

oh, ok, thanks for the new knowledge
