Turbo's vs. blower on Gen 2?

Correct me if I'm wrong but a turbo is much more efficient than say our Eatons right? Turbos will put out anywhere from 75 to 100 percent more power over stock compared to the roots style eaton blower which puts out around 50 percent more power than stock(once again correct me if I'm wrong) so it would seem logical to go with a turbo right? What other changes need to be made for a turbo to work with our motors?

I believe If you shoot the NOS out of the whole this will eliminate some of the lag and make up some of the loss created by a turbo! Although the drivability and all out fun of the blower is now gone. Turbo Navi motor sounds like a 9 sec truck to me?
I just want to smack the ever living heck (LOL not really) out of the people complaining about lack of whine. I mean...have ya ever heard a nasty turbo?????? That is with out a doubt the most sexy noise in the whole wild world of sports (besides tight tennis chicks grunting!!) I mean, the whirr, the whoooosh, the weee....OH MY GOD....I'm going to blow one just thinking about turbo noise!!! BUICK GN's RULE!!! My bud has a TT LS1 with open exhaust, that rules too...it sounds like a 747 on take off when he's just rollin' down the street. In short I LOVE TURBO's!!!!
Would it be better for our trucks? I doubt it, at least for a street truck. I've seen several turbo/twin turbo Gen1's out there...cool yes...low end torque-mongers...eh, not convinced yet!
Oh, ya, watch a pro 5.0 weeeeeeee and woooosh to a 6.xx ya, turbo's are cooooool!

Actually, if you compare a turbo running comparable boost and CFM rating to the Eaton unit, it would only add about 55% more power, not 75% to 100% more. Turbos are more efficient than a crank driven SC, but not that much more efficient.

Dont take your flame suit out, Im just asking. Where do you get these figures ? Lemme give you a few examples of what I know that disputs the above post.
03 Cobra 8#s Eaton Boost 390HP 390FTTQ
03 Mach 1 5# Turbo Boost 396RWHP 426FTTQ
A Turbo is very much more effiecent than a SuperCharger. This is the reason that in any heads up class, Superchargers get alot more cubic inches and sometimes even get weight breaks. What is the CFM rating of the Eaton 112 ?

I have seen many power adder battles in my day...NMCA fastest street car shootouts...nitrous, blower, turbo or just cubic inches....and on any given day all can win....sometimes NOS works the best (Brandon Switzer)for a given track, and sometimes blowers do (Randy Adler)....but one of my favorites was Elias Delatorro and his turbo mustang....talk a bout screaming....this thing will make your old ladys screaming seem faint....
Steele, NHRA top fuel/funny cars must run a roots blower, maximum size 14-71. 19in rotor case length, 11 1/4 case width, max rotor cavity diameter 5.84in. Thats paraphrased from the '03 rule book.

Is practicality an issue for top fuel dragsters? I mean if they blow an engine because they were trying run a turbo set up who pays for it? The sponsors? And can you lose your sponsorship by not being practial with your setup?
after seeing quite a few top fuel drag races, im wondering what kind of turbo would stand up to the insane about of heat the must be generated out of the exhaust. I mean you guys have seen this, 8 4 inch exhausts spitting out fuel and fire all over, i dont think a turbo could take that kind of beating.
Although, maybe running that rich wouldnt be necessary with a turbo? Im kinda curious now too.

Another 500 or 1000hp won't really do anything for a T/F dragster. They already have more power than they can use, and are running at the limits of current tire, track, chassis, safety technology ect. If the car can smoke the tires at 300mph, does it need more power? Also, those zoomie headers are part of the downforce/aero package, what would happen without them? Can a turbo handle the EGTs a nitro motor puts out?
Its fun to dream on someone else's dime, but I doubt we'll ever see a turbo on a T/F dragster.

how about a twin turbo with a whipple 140. haha
i had a picture of a 67 chevy 2 nova with a 454 with twin turbos routed into a big *** (i think) 6-71 blower. man its the sweetest looking setup ever. if i can scan it i'll post it

Please do, that would be freaking insane. I always thought it would be intesting to have a dual stage setup running a S/C all the way up til you get the turbos spun and then bypass the S/C and run off the turbos. Dont know if that would be truly effective or not but who knows. Again, nice to speculate on someone elses dime.
