is it true that sc's wear down your engine fast?
or just a myth?

 

its all how you drive and how its tuned

 

truth

 

well a stock engine running normal sea level has 14.7 psi in the intake. now add a supercharger and increase it by 7-10 psi and like most people, increase fuel rate, etc etc. its not going to decrease engine wear!

 

X2 if you have a good tune and drive like you have a brain you will get 100k+

 

i agree that a properly tuned and well driven s/c motor can last a long time.

but all things being equal, i believe that more often than not a stock vehicle will have less problems in the long run..

 

My lack of extensive physics, or engine knowledge...I would have to believe it would not last as long. Engine is working harder?

 

X3. By the time I get to 100k, I'll probably turn it in for something else anyway.

the easiest way to "add power" to your truck

 

I just rolled over 100K. Motor is still riunning strong and not using any oil (other than blow-by). From day 1 of the install, I had already given the thought of another moter..tranny...rear-end, cause I knew I couldn't keep my foot out of it.....

 

ive read that turbos are easier on ur engine. of course if tuned right and all that

 

A turbo requires less HP to produce the same amount of power as a supercharger. The parasitic loss of a turbo is about 15ph. On a supercharger it is say at least 50 and some times 75. So to produce 400 crank Hp the turbo engine requires 415 where the supercharged engine could require 475. So the turbo requires less out of the engine. So will the blown engine last as long as a N/A engine? The triton's weak point are the rods and then the pistons. The Rods will not live long a levels exceeding 450 hp. If you do not tune right detonation will destroy the pistons. So stay under 450 crank Hp and tune it right and your blown engine should last as long as an N/A version.

i'm running a 302 windsor

 

I've been told and read the ring lands will fold before the rods will break, either way it breaks, but just backwards from what you said. I have also heard the 450 hp is at the wheels, not the motor.

 

Well I hope it's 450 at the wheels! Can't imagine going to the trouble of a Roushcharger for 322 RWHP or less. I think there are plenty of guys running 380-400 RWHP with no problems. It seems like problems with the motor arise from some type of failure, like an injector, clogged fuel filter, bad tune, etc. My mechanic said to make sure and have a fuel pressure gauge and watch during hard acceleration. Fuel pressure drops I guess equals trouble.
