Well I thought it was time to resurrect this novel..lol
Phos or mang bronze???....used forever by the pro racers...great product in its time but now the technology has advanced just like the wooden wheel to inflated rubber tires or from a corded phone to wireless.
After countless hours of research and talking to top engineers from around the world pm guides are the bomb. Though originally developed by bsa and going thru much testeing and developement for diesel engines it is now running in your favorite dailey driver and also F1 engines....just tell those mad scientist what application your engine is for and they'll brew you up a special formula to handle your needs. "0" clearance with no gauling or seizing?? No gualing or seizing with no oil?? Best heat dissapation on the planet?? Got some valve train irregularities that would wallow out your bronze like a 60 year old french hooker?? The pm guides have you covered.
So really good bronze guides have been used forever and they will last longer than the rest of your engine components...RIGHT??? So why go to the pm route...Has anyone looked into the ME and TE of a high performance 9K rpm lightweight screamer?? If you think that the best bronze guides are ok and there is no need to go pm then why not put some snow tires on your 355 CH and do some hot laps....tires are tires right....they are both made out of rubber.
When the rest of your engine goes south atleast the guides won't need replacing..that ought to save you some money on the rebuild..lol
