Supercharger kit for the MP5??????
- Thread starter Z-wagon
- Start date
unforetunately, no! there is alot of interest on this board for a supercharger (me being one), but there are no vendors who supply s/c for the protege community. wagner motorsports has expressed an interest, and I belive one other supplier may have one in the works. but to answer your question in a word, no.

tttP5....geez man. Gotta do some homework for yourself. Go buy a book on Forced Induction. Do a search on Amazon.com. Should be a good read for ya. Just take it slow.

The bigger question is whether supercharger or turbo puts more stress on the bottom end.
Had the same thoughts as you, quicksilver5. It seems like there are alot of people on the board who have been losing their t/c motors lately. I'm wondering if supercharging is less destructive to our motors. When I used to hang out on the Miata boards, I never really heard of anyone losing their s/c motors.

I that it is due to the nature of how each works. The supercharger is more continuous pressure through the entire RPM range; whereas, the turbo builds boost and then shoves it right down the engines throat, so to speak. I think turbos are more sensitive to heat as well. My father and I used to race a modified Buick Grand National (86 intercooled turbo). When cool, it was a high 12 second car. But if we didn't keep it cool and iced, it would run through the traps in low 14's.
Load on the internals is directly related to heat & cylinder pressures. NOT boost pressure. Either one of them can and do cause engine life to decrease. The problem with FI is high rpm and the tensile strenth of the rods. Second is the right management. Detonation will kill an engine that normally doesnt see 100% VE as early as a FI engine does. And for such sustained periods of time in a given drive cycle.quicksilver5 said:
Some of this is correct. The misconception lies in the fact that many people think a turbo doesnt produce the same low end torque as a supercharged engine in theory would. It is because of a significant boost threshold that has to be met. You get that explosive torque increase so suddenly. Dont be fooled. If you look directly at two well tuned FI dyno charts, one with SC and one turbo you will see a much broader and earlier torque curve take form for a turbo charged engine. Again alot of this is generalities here but in lamens terms they are two completely different animals. There are alot of misconceptions in the way some people think they work that is all.quicksilver5 said:
My 2 1/2 cents
Unless the conversation warrants I wont get too technical. As there are AGAIN mixed opinions rather than fact on this subject too. These are the facts.rktktpaul said:
It is not a product of higher boost pressures.
Is it related. Not directly.
Any time you are "forcing" a mixture into the cylinder, rather than inducing it via cylinder vacuum, atmospheric pressure or just plain old scavenging, you increase volumetric efficiency. It is the measure of how well the engine can process the available air and fuel it is given.
Boost pressure is the amount of pressure above atmosheric pressure that is pressing against your intake valve to fill the cylinder and increase your VE.
If you have ever noticed that at every throttle angle, load, gear airtemp, etc you will have a "ideal" timing value. Or initial spark to start the flame front. This is all in accordance with cylinder filling. The more cylinder filling the less advance you will need. Because the cylinder pressures will help move and burn the mixture faster. As cylinder pressures increase and the denser the mixture the faster it will burn once intiated. The key then is to move the timing advance to where it would optimally need it to push the pistons down the bore. Usually around 5-15 Degrees AFTER TDC. (depending on engine design) Timing is very important. It plays a role in power and reliability. It directly affects exhaust gas temperatures, Cylinder pressures and thus the occurance of detonation. If your timing lead is off and starts the process a little too early. "Peak" cylinder pressures will happen BEFORE TDC. That will smack the pistons surface and the harm begins. So I guess what im trying to sum up is the fact that you need to be optimally tuned for the specific application. That way you "minimize" your chances of detonation. Preignition is another story all together but related.
So you can see that boost pressure causes you to increase your volume of potential combustion ingredients but does not directly cause the detonation problems. Your timing lead needs to be "corrected" or implimented to the system correctly.
Just like a car with higher NA static compression characteristics, the timing curve will be completely different then that of basic economy vehicles we see today.
Heat is also a huge factor in detonation. In fact I always thought that detonation was when you had combustion before/after the combustion cycle?
I would think a supercharger would be harder on the engine than a turbo. One thing that I would research first to see whether the FS-DE engine is a good *STOCK* engine to supercharge is the crank strength. I can't remember off the top of my head if the crank is forged or not. Once you figure out what kind of crank your looking at I would move on from there.
There are so many diffrent things you need to take in to account when either supercharging or turbocharging. In my opinion if you want to just set it up and be done with it supercharging is the way to go. Again that is just my opinion.
Damn beat me to it!!!
Im also willing to let them use my car!

Way to go Nick....Just postwhore somewhere else from now on!!
j/k. Very good info for NoObS.

Well contact him directly . I think he is still looking for someone.akhilleus said:

s*** with the new EMS we are working on this will be a nice project.
