Rob just called me. Engine let go this morning in Stockton, on the way to the autocross. (IMG:style_emoticons/default/sad.gif) Sounds like a piston skirt broke off and trapped itself between the crank and case, and then blew its way out. Now he's got to wait for a tow truck. Ooooooh man. Poor Rob. I'm sure he'll have some pictures (with garbage cans) when he get's it back to his place. (IMG:style_emoticons/default/hissyfit.gif) (IMG:style_emoticons/default/barf.gif) |

QUOTE it's amazing what one can learn from these little cars And the assholes that continually make smart assed comments concerning them. Want to learn about the Human Race?? Own a Business and do your best, be intense and take your work seriously... The assholes will always be there, trying to spit in your face and most of them are purely jealous and have never accomplished a damn thing themselves. FWIW I have had several engines die from bad gas.. I once bought a tank full of gas for the dyno out of the same pump that I ALWAYS buy all the dyno gas from.. Got it back to the shop, filled the dyno tank and the EGT was uncontrollable immediately, which was odd because I had just been running the engine and ran out of gas. Brent and I chased the issue for an hour, the EGT got so hot that it scorched a carbon fiber valve cover while we were trying to troubleshoot the issue.. Changed the fuel, problem solved.. Come to find out that some genius put the 87 octane in the 93 tank and vice versa, so I was trying to run a 10.5:1, 200 HP engine on 87 octane and didn't know it... Till we took a whiff of it (yes we are that damn good) and knew it wasn't right. That engine didn't see any damage because it was under telemetry and we saw every move it made.. It has happened to me with race engines and bad race gas as well... Bad gas can and will take out any aircooled engine if its not caught.. Why the hell do you think that airplanes have fuel samples pulled daily??? I have seen 60,000 gallons of JP-5 Jet Fuel test bad and it put our entire squadron on the deck of a carrier.. Those tests are done with a Mason jar and some sunlight.. I try my best to buy gas at the same station and same pump when possible... EVERY time you get a tank of fuel you are taking a chance that it's crappy. This post has been edited by Jake Raby: Jul 15 2009, 09:44 PM |

Bla,bla, bla Another form letter I've seen before, full of invective & specious logic. I can name call also, Jake. You want a taste? It would have to be off line as it is against the rules here. Oh, I forget, you're tight with the admins and rules don't apply to you. I have experienced detonation from an air cooled motor. I couldn't hear it but I could feel it. I quit pushing hard up hill in 3dr gear. No rods popped out of the case....go figure. |

I have experienced detonation from an air cooled motor. I couldn't hear it but I could feel it. I quit pushing hard up hill in 3dr gear. No rods popped out of the case....go figure. Long sweeping right hander at freeway speed. No detonation heard, no change in feel. Just pop, smoke, oil spray... Still ran on the three remaining cylinders. Oh, and no rods popped out of the case... that was piston shrapnel. Same with the wood chipper. Piston blew up. The gas is discolored and separates when you put it in a container into two distinct solutions. Even without analysis I'd say that it is bad. It isn't supposed to do that. I am having a hard time finding your point. Are you a better driver because you felt the detonation? Was the engine better because it didn't blow? Rhetorical of course. I don't really care about your answers. You like six cylinders. We get that. Your always bagging on California and Jake and Type IV motors. We get that. I built this motor. If you want to insult someone pay attention to me. I'm the one you'll piss off. And you can (IMG:style_emoticons/default/KMA.gif) |
