Whipple FTW!

Making full boost at 2,500 RPM is great. You gotta love the lowend torque. Plus Whipple = much less than twins.

I would think for a street vechicle, and a truck at that, that a screw blower would be much better suited than some twins.

If you want to build your truck for pure drag racing purposes then I would say go with the turbos.

 

IMHO with most of us that use them for various things, and aren't convertored to 3,000 rpm, our Heavy Trucks need the Low end Grunt to get it moving, so I say stick with the blower of your choice. If your making just a straight line beast, and not worried about it running anywhere else go turbo.
personally, in our club, we have a few GNs, and other turboed vehicles, about 2 out of the 7 at some point in the season are down from eating up turbo bearings and breaking turbos it seems (not always the same ones) but none of us have toasted a blower, And we don't have to sit on the line and worry about Building boost

 

turbo

 

wow that's convincing

 

LMFAO! Full boost @ 2500 rpm....you must be spinning the hell out of your S/C.
I bet that its curve never stops climbing as well?

 

Care to elaborate on your turbo experience?

 

Well Scott keep laughing. I'm running a 2.93 pulley(about 13 psi) on an unported Eaton, and yes it makes full boost(or close to it) at about 2,500. I don't care what you say a screw blower is better than a pair of big *** turbos on a street vehicle.

Im just laughing cause Ive spun an eaton more than youll ever have. BTW it doesnt and cant make full boost that quick. Also an eaton isnt screw its roots.
Im sure its your vast experience that is telling me the Screw is better than a Turbo.
You are a cheerleader and nothing more.

 

Well your **** and nothing more. Don't talk **** to me. If your stupid enough to believe that having a powerband that last all of 1,500 rpm is better than one that last through your whole RPM range on a street car then have a nut. I would happily give up some topend power for a broad, usable powerband. I don't care how fast you've spun an Eaton. With all the money I've spent on my car I could be doing alot better than the factory blower if thats what I felt like doing with it, but that time will come. And if its like that then I've thrown my car through a turn faster than you ever have, so whatever.

 

Sigh, just plain not true man. A single turbo can without a doubt be made better than a supercharger even on a truck, and especially on a built truck.

People that sit here and talk about "turbo lag" simply don't know what they are talking about. A properly designed and tuned turbo setup will have absolutely no turbo lag...AND, to boot, most people probably have more than enough trouble getting traction off the line, so the supposed downside to the turbos you all keep bagging on would actually help. There is no denying that a turbo will put out more power at the same boost levels...

And before you call me a turbo lover, refer to my first post and my recommendation.

 

WOW I geuss you told me yeesh with all of your experience concerning s/c and turbos I must say Im floored! Your the man!

Can you teach me to throw my truck through the corners?

 

^ Go at it as fast as you can and then lock your wheel in the direction you want to turn.

I'm not saying that your truck is suppose to be a great handling sport car, its just if your wanting to go tit for tat then the suspension is were I've spent the majority of my money on my car and it handles pretty good for a Mustang. I will soon be concentrating on making more power out of my car.

Also if you like Turbos better than screw blowers thats cool, their much more efficient. I prefer the S/C though, and I was just giving my opinion.

 

This is a interesting debate, I think that both peoples opinions are correct. You can go turbo and spend a ***** pot of money and make it faster then a Twin screw all day long, However if you want a street truck that is fun to drive and does not have the inherant troubles that turbo's have then go Twin screw. Now I have had both well kind of, I have not run the twin screw on my lightning yet but its comming. I have a 76 mm turbo set-up that is comming off the truck, beefore I even finished it. Why you ask well I rode in a 76mm street truck and then rode in a Whipple twin screw and hands down the twin screw truck was a much better driving truck, FOR THE STREET however the turbo truck was faster in the 1/4. Both trucks where simillar builds and after I rode in the whipple truck I instantly decided to change directions and now I am in the process of going Whipple 3.4 or Kb 2.6. So in a nut shell for the street I would go Whipple, at the track I would prefer the Turbo truck!

 

Why limit yourselves when you could do both???

There are a bunch of cars to be introduced that will have both a supercharger and a turbo. VW is about to introduce a mid-size SUV with that very set-up. Properly designed, you get the benefits of both without any of the draw backs.

 

if that so true then why are there no TOP FUEL teams that are Turbo!!
