super or turbo

[jordan.v]

thinking about getting a super or a turbo.... i need a little help...

[Bagged02]

supercharger for v-8 IMO.

[jordan.v]

ok thanx

Depends what you want. Parish has turbo on his truck and it hauls some sweet ass.

[James B.]

Well, you pasted the same vague question on a few different forums.

It's like coming in here and saying only "I'm thinking of buying a 2WD truck or a 4WD truck.... and I need help...."

If you want intelligent responses you need to make an effort to provide some up-front information about what your goals and budget are. Everyone has different intentions for their truck and chooses their power-adders accordingly.

well i wanted a vague answer all i wanted was whether super was better than turbo or vice versa... as far as adding power and what the pros and cons are of each...

I agree. Or else you'll get retarded responses from people who have no clue WTF they are talking about. A detailed question usually weeds out the idiots ;)

There is no one better unit. It all depends on the requirements of the individual. The quesiton is compounded by the multiple choices in superchargers as well. :)

Why dont you tell us a lil about your truck and your end goals and typical driving style.

I think turbos are more cooler, 'cause they gotta make more power, 'cause diesels use them, and everyone no's deisels is the most powerfullest motor in the world!

You mean responses like that???

Totally! Hahaha

Depends if you want low end, top end? One's not going to be more poerful than the other, depends on the kit you get. What sized turbo, both applications will require additional modding and lots of upkeep.

But if you wanna go faster, get a turbo cuz a supercharger runs off the engine and uses horsepower to create horsepower, it will help your low end go crazy and break your axles, if you wanna get up to super-high speed freeway action get a turbo.

ok sorry to be such a noob... i have a stock 4.8 i drive about 50+ miles everyday when school is in, i dont kno about the summer but w/e, and i would like to be able to take it to the trak and not get dusted by some little ricer. eventually would like to take on an L and not hve to worry tht im goin to be watching his taillights fade away in the distance.
i appreciate all the help.

[James B.]

Okay, good info. That does change things.

You use this truck for school.
1. Do you have an alternate vehicle to drive when this truck is broken?
2. Will you be happy with a 10-30% reduction in fuel economy?
3. Is making expensive repairs and/or replacing major drivetrain components something that will not be an unmanageable burden while you are attending school?

And for the original question, sounds like you want a good setup for the dragstrip. In that case I would suggest a turbo with a torque converter that has a 3200RPM stall speed.

[F8L Z71]

Like James asked. it is going to come down to what you can afford in the long term not just for the blower kit. If you are a starving student like a lot of us then an expensive blower kit may not be the way to go unless you can get a killer deal on a used one. Even then you have to worry about breaking something expensive.

If you have plenty of money then a turbo kit or a centrifugal blower like the Procharger would work awesome coupled with a 3200-3500 stall. The only drawback is if there are no good tuners in your area as these setups can easily destroy an engine if not tuned properly. If done right not much can top this combo.

If you are a starving student then I would recommend doing a 3000 stall, cam, long tubes and a custom tune and maybe a lil weight reduction. You can easily get a full second difference in the 1/4mile and have a lot of fun with the local ricers and your chances of breaking anything diminish drastically. Later on down the road you can add a blower or turbo as money dictates. :)

[jordan.v]

yeah i am kinda one of those starving students u talk about... i geuss i will have to wait until im outa college, but as a noob im not sure wut the 3000 stall is, i kno wut the others are and those will defiently be in the near future

[jordan.v]

the amount of hp that a super/turbo adds is that just hp or rwhp?

[jeep45238]

Turbo.

More torque, more power, better milage, non-rpm dependant boost.

Only downside is it's slightly more complicated and more expensive to get setup, but the benefits outweight them by far.

[jocww]

twin screw all the way cant beat that whine:scared: :scared:

[Googs]

I'm with James, from what it sounds like you're looking for, a turbo system would suit you. The best parts about a turbo is, under "normal" driving you'll never know it's there, & you'll get the same gas milage, possibly a small improvment.

Stall speed has to do with the torque converter in your trans.

I think the efficiency of a turbocharger is something like 85% whereas a supercharger is only 35-50% efficient. The only horsepower wasted on a turbo setup is the small amount of back pressure, which only wastes something like 15% of the total hp output of the engine. Whereas with a blower (supercharger) you are turning it with a belt from your crankshaft on your engine, so you are losing much more power, that you would have otherwise had if you were turbocharged rather than supercharged.

I think they both require lots of tuning to get it perfect, so that's about the same. If you don't get exactly the right turbo(s) for your engine then you will have some serious lag (too big) (turbo lag (look it up on google)) or not get much top end power, if your turbos are too small. I think with turbocharging you really have to know what the heck you are doing to get it "right". Anyone can build a turbo manifold and slap a turbo on anything, and it will likely start up and run, but either won't perform well or will blow up shortly, but with a supercharger, it's pretty easy. Bolt it on, get a free flowing exhaust installed, get your computer tuned for supercharging, hit the road. And yes, you gotta love that whine from the supercharger, and the low end torque, but I prefer turbochargers and the whistle sound they make, personally, and I like when they come on strong and put you back in the seat while simultaneously going "whoooosh". A good friend of mine had a 94 Toyota Supra twin turbo with all kinds of mods, but still had the factory twins, ran 11's or 12's in the 1/4 mile and riding in that car is a unique experience compared to supercharged cars/trucks. Of course the car wasn't build for drag racing, it still did 170mph or so on the highway, and ran 11's or 12's in the 1/4 mile.

Another friend of mine had a supercharged (whipple) Big block in his boat. It was like a normal engine till he hit the gas hard and it would whine like it was some kind of sick beast coming for the kill... that was awesome too.

I think the turbocharger route is actually less expensive if you are capable of doing most of the work yourself. The companies that make blowers (superchargers) are very proud of them and they cost an arm and a leg.

To each his own, if your a techie nut that likes to get the most out of everything, and not scared to blow stuff up, do a turbo setup, if you are just a normal guy, go buy a blower. Either way you'll like it.....
