rotayt

hey people my 13b bridge port with ida was getting dyno tuned yesterday got all set up on the dyno, set the timing with the iming light and locked the dizzy,



done a first run and found the ida needed to be modifyd took it apart and was jetted out to suit and took out a wall in side the ida for more fuel.



assembled the ida an put it back on and started the next run checking the air fuel ratio an all.



it got opend out to 8000 rpm and it sounded like it rev limited and he picked up sumthng on the knock sensor



as it came down to idol it sounded like like a 6 cylinder



turned it off and he checked a few things out at first he thort he broke a tip on the spark plugs



culdnt find anythng and then we did a compresion test ,the thing he picked up on the knock sensor was a breaking apex seal



and the front rotor was down on compresion aswell , but it had definatly broken a rear apex seal



the motor is roughly 600km old from a brand new re build new housings carbon, apex seals,new bearings with extra windows







im so gutterd about this as i have been building this rx7 up for 3 years.







i am going to talk to my engine builder and try find out why it has done it and hopefully come to an agreement.



as the engine is warranted for the engine build



iv always warmed it up befor i drove it never thrashed the crap out of it always run premix





any help on why you think it has done this will be greatly apreciated, is it the dyno tuners fault?? or the build i dont know
