You are 100% correct. Some people just don't get it. Not only does RPM kill or shorten the life of an engine, so does friction, heat, and the vibrations / harmonics. If others don't agree im sorry, but if you like proof then tear a engine down for yourself. I have built many race engines and every off season a complete tear down was done to replace the bearings, rings and to inspect the internals. The harder you push a engine the less life you'll get from it. Just look at nascar/nhra/ihra/ etc etc. they all get town down and rebuilt with very little run time. The best think you can do if building a engine is use light weight Pistons, rods, crank, a high quality bearing set and rings for your application. It all depends on what your goal and use is. Also to change your oil more frequently and to control the oil temps and make sure the oil system is up to snuff. Don't forget a perfect balance and balancer. Another thing to think of is a oil accumulator.

Thanks I speak from experience as well, I also own an E46 M3 which BMW built with a factory 8000rpm limit. As a few of these cars approached 100,000 miles it became fact the high RPM limit, also found in the V8 M3 was causing premature wear on the shells.

A few people have tuned the M3 past 8000rpm, to say 8500rpm, so a mere 500rpm increase and a few thousand miles later spun a shell or very nearly spun a shell.

As RPM increases so does wear and when your revving past 7000rpm exactly as you say wear increased at an increased rate due to vibrations, harmonics and simple physics more RPM, more heat, more friction all equals more wear on the engine parts.


Anyway it is good to know our engine shares the same critical components such as rod bearing, pistons with the BOSS 302 which had a 7500rpm limit so I am happy to increase my rev limit to this in the knowledge that 100,000 miles later all shall still be well as long as oil is changed more frequently than Ford recommend, say every 5000 miles.

But revving to 8000rpm, even 8250rpm I am sure will be fine on a fairly new engine, but if the car is used daily and does indeed see 8000rpm daily I'd be inspecting the shells every 50,000 miles and keeping my ears open for bottom end knock just in case. As such I'd rather just play it safe and not have that worry. But my car is a daily so I need reliability, if the car was just a weekend car or raced at the strip and I had a slush fund then yeah I'd happily take it to 8000rpm and IF it did spin a shell or put a piston through the block I'd know why.

But as you say, you are spot on, when you get to very high RPM's more wear occurs it is why motorbike engines need rebuilds but motorbike engines are cheap.

I dowel pinned bearings before and that will keep the bearing from spinning. But I've also seen them fail, but on a VERY rare occasion.

Lol yaok

The numbers are not that impressive guys. Trust me. But I guess if you compare it to the price of the Cj intake it's ok.

Link please?

I'm a bit disappointed in the numbers. I should have just gotten the GT350 manifold when it was on sale, instead of waiting for these poor numbers...

Link please?

its april fools there is no link

Hahahah ffff

When they called this thread "TEASER" they weren't kidding. Damn near 2 months to the day and 25 pages and still no info. We were all made in 9 months! I thought the wait for my Shelby was long. Damn.
