Anyone running a super-charger in their Rams? Anybody have any opinions on different super-charger manufacturers? Price, Performance, Quality, etc...

Kenne Bell?
Paxton?
Powerdyne?
Vortech?

I dont have one or any experience - yet. I do know that the Kenne Bell will give you more bottom end power than the other three you listed, because of the type of blower that it is. The centrifugal's are better for mid to upper RPM power.

Tunis,

If its one thing I know it is Superchargers.. I have installed several of them.
Paxton, Powerdyne, Vortech, ATI Procharger.

I think that the Kenne Bell is the only one I havent done.

Currently all of them make kits for the Ram other the ATI and they are working on it. I saw a picture of a prototype.

The only one that I would really want on a truck is the Kenne Bell since it is made more for torque that HP.

You will see full boost anytime you hit full throttle above about 2000 rpm.

Most of the kits are in the $3500-$4500 range but do come complete with everything you need to install them.
IF you want a Vortech, Paxton, or Powerdyne let me know. I have a friend that is a dealer and can get you a good price.

Can't go wrong with Kenne Bell but I've seen an article on the vortec supercharger and the 5.9L Dodge got 460 ft lbs. of torque which is not bad for low end power.

Bill,

That's awesome! Yes, I'm very interested! I was looking into the Powerdyne Super-Charger...they are priced very reasonable (under $3000.00) and produce about 6psi of boost. Could you get me a price for each system? Thanks Bill... <IMG SRC="/board/images/smilies/bigthumbup.gif">

Tunis,

Check out his web site.
http://www.need-4-speed.com
He is based out of Florida so you don't have to pay any taxes. Shipping on most kits is about $50.
He has prices for the Vortech and Powerdyne on his site already. If you call him let him know that you are a friend of mine and he may be able to give you a better deal. The prices on his site are low to start with. He doesnt mark up superchargers very much.

Talk to "cmyindy" on http://www.dodgetrucks.org He is running a supercharge, you might want to talk with him.

I'm looking for some type of forced induction and i think the best is a turbo kit.but most important is an intercooler, because when you compress air, it gets hot, and hot air has less oxigen, which means less power. A turbo, on the other hand, doesn't rob power from the engine to do its work, it uses the exhaust fumes (a blower can take as much as 15% of the power it delivers to do its job, but a turbo only 3 to 5%)that's why turbos are so popular on small cars. And about turbo lag, it all depends on the turbo you use. Diesel trucks have little or no lag, because quickly spool up, so you need a turbo that spool up fast too. y the way, i'm from Chile.

a turbo doesnt do you any good off road when your not going very fast to have the motor spool up the turbo. a turbo doesnt really start making power till around 2000 rpm. and if your just crawling around trying not to bang things up you really dont see anything over 2000 rpm. a blower makes power at any rpm. also it probaly cheaper to setup than a supercharger.

Compressed air is hotter than non-compressed air, but does not have less oxygen. Hot air is less dense than cold air, therefore you can't pack as much into the cylinder as you could if the air was cooler, thus the importance of an intercooler.

Anybody knows of a V-8 turbocharged Ram in your country? with a friend were thinking of installing a couple of turbos on one, but maybe is too complicated. Kits, anyone?

Maybe you're right, but this truck need power for sand, so low end torque is not that important. Besides, a blower with m6 psi of boost pressure gives me only 90 h.p., while a turbo with the same pressure could give me something like 120 h.p. Turbochargers are much more efficient than blowers. When was the last time that you saw a supercharged Kenworth?

comparing apples to oranges arent we? yes if your drag racing and have a ton of cash go for the turbo. since this is an offroad board we dont drag our 4x4s(and if you do well thats your own thing). for one your comparing a industrial diesel engine that can see a million miles and is a totally different setup to a gas engine thats lucky to see 100k before a major failure. a blower will give full boost around 2k rpm, while a turbo will need to see 4-5k before full boost. which do you think is easier on a motor a turbo or a blower. obviously its the blower since it doesnt have to rev close to redline to make the same numbers the way a turbo has to. 4cyls is a different ballgame compared to a v8. they have less moving parts since most are an overhead cam, so a hi-po 4cyl can run around 7k and up rpm range and use a turbo. ever check the cost of a turbo kit. minimum 4k, and thats just for a kit that will only get you 100hp. no i can take $3500, hand that over to kenne bell get 100hp and have that power at around 2k rpm. now tell me which one is more efficent.

Shawn is correct... Turbo's are used on diesels but not hi reving turbos. Think about it... Diesels redline about 4-5K (common redline, some are lower some higher). They don't make power up high normally which is why the turbo is there... to help the powerband.

Superchargers are more commonly used on gasoline engine due to the reliability and ease of use. Turbos are a pain to install... you have to change your whole exhaust setup to accomodate the turbo where as superchargers come with the necessary ducting for intake. Superchargers are more reliable because technology has reworked them again and again. I used a 14psi blower on my '96 Z-28 383 Stroker LT-1 and got up to 613 Rearwheel HP. Paxton is my brand of choice, but they are all pretty equal in performance/reliability.

You can go with a sealed or oiled system. Oil systems are nice but can be a pain because you have to either drain/fill the blower or plumb it into your oil system. I had a sealed blower on my Z and never had a problem with it.

But... the choice is yours.

've tried to know prices of kenne-bell blowers, but i can't find any. I found a turbo kit for Rams and cost $3100(www.turbopower.bigstep.com) and the price of a vortech V-2 SQ is $4.000. I just need some kind of forced induction but with intercooler, because that's important, and i know that turbos are MUCH more efficient, and the not work only at the top end, besides, i don't need too much low end, i already have 4.56's, but on sand it dies, badly (i was humilliated by a Samurai!!, but with a twin cam motor and turbo) so i ask here because its obvious that you've much more experience with blowers and stuff (over here, there is no much late model V-8 supercharged trucks, as you may understand), but you have a lot.

I would still go with a supercharger... turbo's are not that much more reliable. What I meant to say, and what I think Shawn meant too (not putting words into his mouth if he didn't) is that turbo's don't make power very steadily until high rpm's. They will make some increase as the throttle increases (as the exhaust gas increases because thats how they work) but the powerband of a turbo is real sparatic. Superchargers being belt driven are forcing air from idle all the way to redline so your powerband is alot smoother and with less flatspots.

Plus like I said if you get in with turbo's your talking $3,100 for the turbo kit. That doesn't include the larger exhaust you'll need, the various brackets to mount the turbo to your exhaust manifolds (yeah you'll need anew setup there as well....). Its just ALOT of work, where you could get a supercharger and install it in an afternoon and be done with it. Superchargers are the modern day turbo of ole'.

FYI an auction on ebay just closed for a kenne bell supercharger for $1400. also kenne bell claims that his 'chargers dont need an intercooler. from the look of it is because they have an aluminum casting that goes from the whipplecharger to the intake and doesnt have the thin tubing in between like the others. he has a website thats underconstruction its http://www.kennebell.net, i think you can pull a phone number off that.

p.s. chris, thanks alot, i have a hard time explaining things verbally sometimes. i looking to put a turbo on my 2wd nissan kingcab, but so far i havent seen one for an '87, might have to swap a newer 240sx motor in it to get the turbo. i wonder what a built up turbo charged 4cyl on NOS will do in the 1/4 in a pickup?

No problem :wink: Terminology is a PITA.

Secondly, Becareful spraying NOS and a turbo!.... I had that blower on my Z and NOS, but I ran NOS more as a intercooler (because basically all NOS is is REALLY cold air). I was only spraying a 50hp shot after the blower but before my intake to cool the air down alot. With it being a 50hp shot I actually made about 80hp from it. Because not only the NOS, but it was cooling the air better so the blower could stuff more air into the cylanders. Just do some research before you spray and turbo.

So I don't think that everyone understands that all superchargers are RPM dependant on boost and only make boost at wide open throttle.
turbos can make boost at lower rpm but still only at wide open throttle.
the kenne bell will make more boost at lower rpm since it is a roots style unlike the vortech or paxton that won't make full boost till like 5k rpm.

Superchargers are not RPM dependant... TURBOS are because they are driven by exhaust gas. Superchargers are belt driven there for they are constant power.

Blowers and turbos can make power at both ends of the rpm band. it all depends on how the driving force (ie. belt, exhast) is geared. The turbos in diesels will spool up at lower rpm's because thats where they need the power most. Blowers do not give constant or "always on" power. If they were to be producing boost all the time, how would the engine stop? the blower would be forcing the air through the intake system and past the throttle blades, basically just climbing the rpm's. turbos are the same way. thats why they use blow-off valves. to release sudden spikes in pressure.

Here is a <!-- BBCode u2 Start -->http://www.paxtonauto.com/tech/" TARGET="_blank<!-- BBCode u2 End --> straight from Paxton's website:
"Q: Is the supercharger always working?
A: While the supercharger is always spinning and moving air, it is not always producing boost in the engine. Boost is a function of engine load and RPM. The majority of the time your supercharger will not be producing boost. The supercharger produces boost under high load conditions which may include heavy acceleration, going uphill, passing another vehicle or under towing conditions. Paxton superchargers offer the power you need on demand, the reminder of the time the engine is working just like a normally aspirated engine."

iS KENNE-BELL A ROOTS-TYPE BLOWER? I THINKIS A SCREW TYPE, WHICH IS MORE EFFECTIVE THAN A ROOTS. .ANYWAY, ANY BLOWER SHOULD HAVE AN INTERCOOLER. iT MAKES THEM MORE EFFICIENT (EITHER WAY, I PREFER A TURBOCHARGER, I LOVE THE WHISTLE)
