turbotrana Member 2,586 Member For: 21y 11m 7d Gender: Male Posted 16/10/06 01:45 PM Share Posted 16/10/06 01:45 PM There are two types of piston failures. The catastrophic where the piston totally breaks apart and the rod makes a mess of the cylinder and there is the non catestrophic where you may break a ring land or put a hole in the piston, usually thru bad tuning. Usually not a big deal. Just put a new piston in.I have yet to see a catastrophic failure in a BA turbo piston. I have also pushed around 500 rwhp thru a stock ED piston and only ever had ring land failure. The current generation of ACL performance pistons is surprisingly good.If anyone has had a catastrophic failure lets hear about it. Link to comment Share on other sites More sharing options...

Makes me wonder why people are forking out the big bucks for the built motors Link to comment Share on other sites More sharing options...

I think it may of been the rod failing not the piston though. Maybe DBOSS can enlighten us as to what actually happened and how much power he was running.

I didn't want to end up a tilt tray with a busted engine or worse How long would a stock bottom end last with 400+rwkw's? I certainly did not want to find out the hard way and be worried everytime I put my foot down. What if you wreck the head when a rod lets go or a piece of piston goes through it??

I decided to try out some of Royal Purple eng oil that seems to be all the rage at the moment and im quite surprised at the difference it made to the cold rattle. The motor used to produce piston noise between aprox 1100 and 1600 under no load. the range has reduced to aprox1300 to 1500 rpm and is barely audible from inside the car,(although it was always pretty hard to hear it over the t56 anyway....) the oil was quite expensive but seems to be doing the trick at the moment. Apparently 10000k's is the recommended interval for the 5w30 with a filter change around 5000k's. So although the oil is basically twice the price of regular oil, the extended interval (i would normally change it at 5000) may mean it works out around the same. I have a clean control sample and i'l be getting another sample done in 5000k's to see how its holding up.... Link to comment Share on other sites More sharing options...

Makes me wonder why people are forking out the big bucks for the built motors ←I think many of us are happy enough with the performance gains with the stock bottom end. 11's are achievable quite easily now, with aftermarket addons and a good tune, and that's exceptional for a street car.Going quicker becomes a costly exercise..... I think most guys who are powering up their T's are aware that 330 rwkw is around the mark for maintaining reliability with the stock bottom end.Most workshops have been responsible enough to tell their clients that if chasing more power, a stronger rod (at the least) is required.I guess, if replacing rods, may as well set up the whole bottom end properly whilst its off the road... (stronger balanced crank, rods and pistons)That takes the cost of upping the ante quite significantly.Then there is the requirement for a roll cage if breaking into the 10's.... more cost.Gearbox limitations are also holding back many from chasing more power.Once the gearbox limitation is rectified, I think quite a few more T owners might exercise their wallets for the next benchmark of 400+ rwkw and easy 10's!cheerstom Link to comment Share on other sites More sharing options...

They were tuned by "local QLD tuners". Edited 20/10/06 05:42 AM by Adam Link to comment Share on other sites More sharing options...
