Hi everyone i was wondering if anyone could point me in the right direction and technical advice about supercharging my engine (2.3 8V) websites/dealers. Its a real beauty but just underpowered would have loved a 3litre but the price of fuel in the u.k is just to expensive to run a 3.0. So please any replies recieved will be greatly appreciated thanks in advance Nick.

Nick,
Can understand you're wanting more power in a 3500lb car than the 2.3 has but don't think anyone has a kit to fit that motor.

Suggest you put a 2.6/6cyl in the car and find a kit for it as companies as Mosellman etc make kits for the 3.0 and the 2.6 is the same configuration. If you tell them the application they can advise you and help with a kit. As they say, nothing beats cubic inches (millimeters) but the price of gas is the downside of power so you have to find the balance you're satisfied with.

Good luck,

TobiasMB

As Tobias wisely noted, whenever you add (big) power to a car you invariably lose some MPG. Granted there are better power/gallon ways to get it. Some of these can depend on how you need that power. If you only need the extra power very occasionally but "when you want it, you want it NOW" go for NOS. Its easy, cheap (compared to other alternatives), and provided you don't run more than the driveline can take, is fairly safe. If you want more power all the time, all rpm bands, etc....either a supercharger or displacement bump are the only good alternatives. For more top-end power and reasonable efficiency, I would consider a turbo kit. Unfortunately I do not know of any turbo kits for your application, but you may be able to adapt a kit for a 190 2.3 8v to work in your car. You'd surely have to get some custom bits done, but the 190 kit would be a good starting point. The only other thing I could think of would be looking into finding a Roots style supercharger and doing your own kit. Then again, if you would like more luxury, zero engineering/headaches, more power, and keep resale value intact just trade up to a faster factory model.

Hope this helps,
Lee

You may be better of going with a camshaft upgrade from Brabus or some of the others.

Howdy,

Not too familiar with what's available for MB, but I have a Chevrolet performance background. Here's my $.02:

(1) Nitrous: Good--easy to install, moderate to extreme increases in HP, high HP/$$ ratio, can stay emmissions legal, no impact on economy. Bad--only runs in short bursts (for drag racing or stoplight street racing), WILL blow your engine if additional fuel is not provided via a fueler unit.

(2) Supercharger: This is actually 2 categories: centrifugal and roots style. Centrifugal are much more popular as add on kits cause they have very little affect on driveability as long as you "stay out of it". There are multiple Roots or screw types out there as OEM installations due to their silence and their low RPM boost. Good--power always available (only at higher RPM's for centrifugal units), very high HP available with compression ratio changes, cool whining sound coming from your car (you can buy silent units now), amount of boost easily controllable with pulley changes, can remain emissions legal (or at least pass a sniffer test). Bad--kits can be expensive, centrifugal units have been known to fail spectacularly (mostly by people who run them too fast), WILL blow your engine up without providing additional fuel using a fueler unit, timing retard unit also required for higher boost levels, $$$.

(3) Heads/cam: You probably need head porting work, a free flow exhaust and intake, along with a more agressive camshaft if you are to see any benefit. A cam alone that is agressive enough to provide a significant HP boost will kill your low end torque. Good--significant HP boost possible, high rev "fun" power, works well with displacement increases, no problems with leaning/engine blowups. Bad--loss of low end HP if cam is not selected as a system along with exhaust/intake/head changes. Can't pass emissions with very agressive cam, doesn't idle well, no fun to drive in town (low RPM), going to require a fuel curve recalibration if very agressive.

(4) Turbo: Turbo's are cool because boost is available at very low RPM's (so long as you get past the lag). Turbo's are uncool because they have a significant amount of plumbing necessary over and above the technical challenges required for a centrifucgal supercharger.

Here's the route I'd take to more performance:

(1) free flow exhaust/cold air intake--worth as much as 10 - 20 HP. These are FREE HP as well, so your mileage will go up and these changes don't affect emissions.

(2) Nitrous if your interested in stoplight action. Most nitrous systems are wired for full throttle only, so you can drive your car normally until you want it. But, since their wired for full throttle, you have your normal car until you floor it and then you have 2X your normal car. I'm not sure this improves going around the twisties very much.

(3) Low boost supercharger. I'd go with Powerdyne (http://www.powerdyne.com/) because they are belt driven (silent) and therefore does not require you to tap into your engine's oiling system.

(4) High boost supercharger. Units like Vortech and ATI procharger are much more powerful than the Procharger but also more of a hastle. Both these companies, however, have more vareity of choices and cater to home made systems.

(5) Heads/cam/displacement changes. More dollars.

(6) Turbo. It can be done. Check it out: http://www.xmission.com/~dempsey/minivan/

Just my 2 cents.

Sholin
