turbo or s/c ?
 

just looking for pro's and con's to increase hp on daily driver?any thoughts?

If I were you I would go with a turbo kit.

Though they are more expensive they are (from what I hear) alot more efficent than a supercharger.

Turbos run off exhaust which from what I understand don't put any wear on your engine internals.

Superchargers from what I understand do put more wear on your engine internals and because of there pully system it will take horsepower to make horsepower.

All in all...you can make alot more horsepower with a turbo than you can with a supercharger.

There has been extensive debate on this issue in the past. Do a search and you're bound to find numerous threads detailing the pros and cons.

there hasnt been to much talk on this board about the difference between the two.
it can go both ways, but if you want to go easyer on it i think this makes sence :wink:
but ppl may say different.

MY OPINION go turbo!!! As noted it doesn't use horsepower to make horsepower. If you're not on the throttle you aren't making boost. The 1997-2004 Buick regals GS guys are swaping from M90 superchargers to Turbo set ups for racing. There are a few around that have done this swap. Anyone that goes to Sparta will see a Blue Regal GS running a turbo set up!!!

Well maybe I'll try sparta once more when i go instead of Grand Bend. I'll be starting to put all my twin turbo stuff after I try once more for 12.999 on the E6 heads......I just wish they weren't so worn out :( and that I had some slicks on a light rim as opposed to my 10.5 10 year old ET Streets on 7 inch turbines

Very true.

Any boost added to the engine puts wear on it.

The pulley system can put a side load on the crank bearing. If you have a proper pullet system and don't reef the crap out of the blower, pulley, it's a mute point.

Not true. You can make a boatload of power with either.

Same applies to centri blowers
For a daily driver, you could go either way. It depends on the cash you have to spend. Both are proven to work well.

TURBO all the way :biggrin:

Most importantly there is a big difference in price between the two.

fell apon this thread, hope it helps, :tup

1. Turbo's are more "efficient" than a Supercharger, IE, they don't take power to make power like a Supercharger does.

2. Turbo's require more plumbing (single Turbo) or a LOT more plumbing (Twin Turbo) to install. They are typically harder on the engine oil (they have extremely hot exhaust gasses going through them all the time) which may or may not be an issue, depending on how you look at it.

3. On a 302, you can make more power RELIABLY with a Turbo because of the lack of parasitic drag on the engine. With EITHER form of forced-induction you can make enough power to split the block, this is a given, with a Supercharger, that number is ~500RWHP, with a Turbo, that number is ~600RWHP, why? Because technically, both motors are making the same power. The difference is, the Turbo doesn't TAKE any power to run, so the 600RWHP is delivered to the wheels, where as on the Supercharged car, there is a 100HP loss required to run the blower. The 100HP is relative of course, not all of them take that much power, some take less, some take more, its very dependant upon the blower in question and what the actual power numbers you are making are, but its a good point of reference anyways. The same goes for the block, not all stock bottom-ended 302's will take 500/600RWHP reliably, but some will, again, just an average point of reference.

4. Cost and labour: The Supercharger is MUCH easier to install and is much less labour-intensive, this can often be the biggest factor in some people's minds; having their car down for a day or two rather than a week or two for plumbing in the Turbo setup.

5. Tuning: Turbo setups can be more difficult to tune as well, this can also be a factor and a number of people will end up running stand alone fuel management systems in order to tune their setups correctly, like FAST systems and the like.



Hopefully this information is helpful.

Basically for a daily driver, a supercharger would be the logical choice, a roots-style would be optimum, but a centri would work well too, I guess it all depends on what you want. A centrifugal works best at higher rpm, a roots better at lowerrpm, more of a flat power curve, also easier on the engine IMO, a roots of course is more expensive, the KB unit is very nice, if you can afford it.

Depends on your pocket book..

If your planning on spending some coin.. Twin Turbo would be where I would toss my money.

Turbo = free boost. Supercharger takes power to make power. :biggrin:

I was sold on turbos until I figure out it would cost me about 3k plus tuning and a supercharger w/intercooler is gonna cost me 1500, plus tuning.Both used prices)
Since I want to install my self and this is my first power adder, im gonna go with the s/c.
cheaper and easier, and with my combo about the same hp.
just more boost to get the hp level with s/c.
:poke: its the turbo vs s/c war.....

thanks for the input already went with the s/c and had a Kenne Bell Blowzilla installed @ PSP by Paul and it runs great.

Every one is saying that turbos are "free power" and that s/c's take power to make power. When both require power to make power, with a turbo you are suvearly restrict exhaust flow in order to spin the impellers, and make boost. As well you are going to have to wait for that flow to gain enough momentum to make boost, ie turbo lag, this lag could be shortened by going to a twin turbo set up, a shorter spool time but less top end than a massive single. Really, power is cool how ever you make it :thumb1:
