Supercharger and bottom

[SMCBUILDERSINC]

How long can a stock bottom end on one of the high horespower charged kits last under a lead footed driver? Im talking about the 750 and 850 rwhp cars and the factory forged pistons cars. Do the rings tend to wear out causing loss of compression under continuous loads of 10-12 PSI?

Seems to work fine, so far...

about 28,000- 30,000 dialy driven miles and runs like a clock. Only complaint I have is I'm corrupted and NEED MORE POWER. I explained a little more on the alley site.

So far over 30,000 sc miles. i havent noticed any extra oil burning but if i did i wouldnt be disappointed. If i had to put a new motor in today i would have no complaints, i got some hard earned miles.

I had forged pistons put in my otherwise stock bottom end car. It gets a lot of driving and abuse with NO problems. I'm running about 12 psi of boost and make about 843 rwhp.

I ordered a Roe super charger. Does that one only run five pounds? Shoud I be looking at others? I already have a Venom 500 package on it.

The stock forged TRW pistons & rings will survive on a well tuned forced induction engine. The top piston ring land on the stock forged piston is located 0.280" from the top of the piston. The cast Mahle pistons have the top ring land located 0.156" from the top of the piston. Of course, the piston with the ring closer to the top of the piston is most vulnerable to the harsh elements.

Detonation and excessive combustion chamber heat causes piston rings to lose their tension, rob engine performance and enhances even more detonation - oil in fuel
reduces octane. Running over-rich fuel mixtures (referred to as "bore wash") removes much needed oil lubrication off the cylinder walls and causes premature ring and piston wear.

With a properly tuned supercharger package your stock piston/ring combo can survive.

Best of luck,
Doug

Well said Doug.... So far so good here .
