super charger.....

[chevyndn]

i was wondering what kind of super chargers everyone is using, and what kind of price range i am lookin at. also what kind of specs on the engines. i know of vortech and pro chagers, but im tryin to decide what is the best bang for the buck.

[americanmusc1e]

not all of us are running superchargers, some of us run Nitrous and some run turbos..................JK

give some info on your engine and transmission before we can help you.

If you have a nice ZZ502 Big block, you'd neeed something quite different from a stock 350

[Ackattack]

I'm thinking of running a Magnacharger or a Kenne Bell on my 5.3L

[chevyndn]

Well i got a mild 383 and am wanting a super chager, but im not sure what one is better, or if your just buting a name or whatever.... but its a 383 with 10 to 1 comp. weind team g intake with a 750 holley up to, i cant remeber the specs on the cam tho...im just tryin to get some ideas on the set-ups

I have a Procharger on my boat running 7 psi of boost and it gives me 540 HP from a 383 I am running a intercooler but still have to use 92 octane gas. The unit was simple to install and cost $4800. Procharger says you can run them on a healthy stock engine. What I like most is you cruise at less RPM's

[BossHogg69]

if you're wanting to run much boost, you'll have to get that compression ratio down a couple points... So figure some new dished pistons into the equation from the get-go.

[PanelDeland]

Your compression is pretty high for a street supercharger.Are you looking for the performance or for the "WOW" factor?Most recommendations for a street supercharged engine I have seen try to limit CR to about 8:1.Not trying to rain on your parade but you really need to balance the combination to make a supercharger work well.

Most supercharged engines run lower compression pistons and use the boost to raise compression. You can call Procharger and they will give lots of free info. Their web site is procharger.com

ok....thanks for the info every one!!!!!

As outlined above, you've really got too much compression to run a blower. 9:1 is probably about the max you should run on the street with a blower...and that's max. Less would be better.

nevertheless, a lot of people don't think about them much anymore but the older style roots draw-thru street blowers really work pretty good for what they are, and the beauty of them is that they are cheap in comparison to the centrifugal chargers. Another bonus is that one of those will fit under the stock hood in our trucks. I'm referring to something like a Weiand or B&M 144, 112 Magna-Charger, etc. If you look around you can pick one of those up for under $1000....they are real easy to install, still have good driveability, good blower sound (whine), and they make pretty impressive power....a lot of torque, which is good for our trucks too b/c lets face it, they are heavy vehicles. You can run a regular Holley or Edelbrock carb with the draw-thru design too....no need for high dollar blow-thru prepped carbs with positive floats, etc.

I have a friend that used to run an older B&M on a fairly mild combination 350 SBC in a 68' GMC.....it had just enough duration with the cam that when combined with the blower sounded tough as nails at idle. The only problem with the truck is that he could never get it to hook....but from a roll it surprised a lot of people.

i guess if push come to shove i can blow the dust off the 12.5 to 1 high domes i got layin around and build an all motor power plant....

Good luck finding fuel for it

My buddy has a 300hp GM crate motor, with a 142cu. weiand supercharger, with a single 750 carb with 6lbs of boost and it made 417hp and 505lbs of torque to the tire, I thought that was dang good for a stock crate 350..350 was around 2200$ and supercharger was 1900$ not bad..

I gotta agree, if you're going for all-out power and maximum expense, go big with a big procharger or BDS 8-71....................otherwise, for a 350, use a weiand 142 and for a 383 use a weiand 177.

OR........if you wanna retain SOME fuel economy (with more initial expense), go with a Edelbrock or TFS Eaton-based MP122 blower.

I wanted to do a turbo charged 8/71 on Nitrous but I'm having some conception troubles.

[chevyndn]

I'm like the rest of you, Ive got a craving for power.... but I'm not sure witch way i wanna go about it.... with a super charger i could get away with premium, with a high dome piston id have to go high octane than that.... but nitrous i think is a cheap but efficient way to go, but I'm not sure what i wanna do yet.... I've managed to come across a lot of stuff this far. maybe ill find a good deal on the other stuff i want to.

[prostreetC-10]

Pros about a super charger or blower is that it's constant power. The NOS is just a button that can't be used all the time. This is assuming we are talking on the street.

[Hart_Rod]

I'm running a Vortech supercharger on my 383. It's got 9:1 compression and dyno'd over 630 TQ and HP, . I've been very happy with it.

[c10addict]

I have one on the shelf but can not decide what I want to put it on... 68, the 64 or one of my other projects ????

[prostreetC-10]

Hart Rod is a show-off!!!

I can't remember if we ever figured out what that vomit color our trucks are painted is called?

Do you know what psi booster that thing puts out??

Just do it!

Brown,

I'm not sure how much boost I'm running, I need to install a boost gauge, .

[mplex2000]

If you go with anything but a roots blower you might be able to get away with that compression. Roots is cool but roots intake temps are hot!!

I have run moderate turbo setups on engines from 9 to 10 compression on 93 octane without issues.

[chevyndn]

hmmmm. thanks againg for all the info guys
