Supercharger Question

kei169 · 03-24-2008, 03:29 AM

hi everyone,

I really desire to add a supercharger in my car. my current milage is 65000. I am wondering, if i add in this point, will i shorten the life of my engine and blow off very quickly??

Thanks

What year and what transmission do you have. And any form of FI will shorten your engine life.

all depends on how you run your car with the SC. i dont push mine hard well not that much. just maintain your car and you should be good

i am having a 04 auto!!

How much on wheel hp will it add more?
How is the 0-60miles result?

my car put down 242 to the wheels.

i have an 04 6 speed

An input supercharger, there's LOTS of info already strewn about this forum on it.

if tuned incorrectly. I've seen turbocharged/supercharged cars that has well over 300K miles on them. Its a matter of proper tune, and religious preventive maintenance.

I'm pretty sure a supercharger will shorten any engine life, no matter how many/little miles are on it. Like people have been saying, engine life expectancy is dependent on how hard you drive.

you will be fine as long as the motor is sound condition before the install and the tune is good. Id do a leakdown and compression to get an idea of your motors health. 99% chance it should be fine. as far as reducing engine life, ive been turboed 7 years and 50,000miles with 52 dyno pulls and 75 track passes. motor still compressions in the 210s and leak down is 3% across all four.

the two greatest stress or forces acted upon the rotating assembly are tensile and compressive forces. increasing either will to some extent increase wear and service intervals. it also makes it more difficult to maintain the clearances of the unit aka the rotating assembly and short block. increasing rpm increases tensile stress to a greater extent than increases in cylinder pressure and therefore compressive forces via forced induction to a point, obviously not including pre ignition or detonation. its also important to remember that i believe all k-series motors went to screw in rod bolts instead of the stronger pass thru design. im assuming that k rods at least have the bigger 9mm bolts of some of the better honda engines, but im not sure. anyways rod bolts only affect tensile strength. i would feel more comfortable on the stock rotating assembly to increase power by increasing cylinder pressure via forced induction than by increasing rpm, to an extent. or maybe i should put it this way, on a modern engine with a forged rotating assembly minus pistons aka forged crank and rods and a well designed head i would feel more comfortable with forced induction than spinning the motor sky high. plus anymore so many oems skimp out on rod bolts anymore.

Just trade your car in for a 2008 bmw 335i.

To TurboB18C1DC2. That's a lot of scientific words and mumbo jumbo. You clearly know more than me. But just to get it straight...

Theoretically a supercharger is less of a strain on n Honda engine IF the person drives at the same speed (using induction to compensate for non-induced RPMs). And thats IF they don't take advantage of the supercharger and actually drive faster (like I would)?

I have no idea what TurboB18C1DC2 said but S/Cing is worse than T/C because its driven directly by the engine, you are always on boost whether your engine is on load or off load. As opposed to T/C, if tuned properly, you are only on boost at WOT, or when your engine is on load. Thats why a S/C engine will have worse fuel economy compared to the same engine that has been T/C'ed

Not true at all. You are not always under boost with a supercharger. Driving normal you may never hit boost just like a turbo charger.

As for fuel economy, you make it sound like a supercharger gets horrible mpg compared to a turbo charger. Even with a supercharger and proper tuning you should still get better gas mileage than a stock engine. It's all about the tuning either way. A properly tuned engine, reguardless of what mods are done to it should last a long time. Of course the more you beat on it and race it, the higher chance of having a problem, but this is also true with a stock engine. But again, it all comes down to the proper tuning and if done correctly, will be completely safe on the motor.

What TurboB18C1DC2 is basically saying is people always feel that forced induction is worse than modding your engine the N/A route. When you do an equivalent N/A build, to take full advantage you will need to rev the engine to higher rpms therefore putting a different type of strain on the motor and possibly causing differnet types of problems that may actually have a higher chance of happening than the problems that could arise from forced induction.

eaton m62s and m48s all have integral bypass valves for part throttle. yes its crank driven but i havent seen anyone have irregular main bearing wear because of a supercharger.
