Fishey Posted October 2, 2007 Report Share Posted October 2, 2007 A picture of the piston would explain everything..However, its obviously detonation caused by running to lean.Also, after reading about that company all I needed to do was read the information they posted and I found it to be laughable. I surely hope no one takes the company seriously when they use incorrect words and poor technical advice regarding turbos.Strait from the site...I about cried when I was laughing at this...

Boomin850 Posted October 2, 2007 Report Share Posted October 2, 2007 The picture I put up was from an engine with rods that were perfectly fine...it was custom tuned by RICA though. Not my car though when it happened Link to comment Share on other sites More sharing options...

Aequitas_Veritas Posted October 2, 2007 Report Share Posted October 2, 2007 How much HP did your car put down with the custom tune on the 19T?he didnt dyno in the whole week or two from the time it was together to the time his rod was bent.

Boomin850 Posted October 2, 2007 Report Share Posted October 2, 2007 How much HP did your car put down with the custom tune on the 19T?No idea...this was from "Rickards" car. When I bought it I tore the engine down and that's what I foundhe didnt dyno in the whole week or two from the time it was together to the time his rod was bent.2wks on the money ;) Link to comment Share on other sites More sharing options...
EricF Posted October 2, 2007 Report Share Posted October 2, 2007 What was he flooring it the whole 3 hours? Definitely looks to me like overheating, too much load and/or timing for the coolant system to keep up with... Which in 850s is quite a bit of load, probably what peoples' pistons look like when they have failures trying to do top speed runs.Here is a piston in a bone stock 855 turbo I purchased some time ago:That car wasn't poorly tuned, and wasn't running a crappy turbo... It's just a matter of pushing a car too hard. Detonation will bend the rods or maybe break the ring lands, heat melts pistons ( duh). Think it would be very odd for a piston to be able to melt from detonation in one of these engines without throwing a rod first. Link to comment Share on other sites More sharing options...
