I don't understand what you're saying here? You damaged your motor due to an issue with the supercharger installed?

Tough to say if it was a pre-existing problem or not , would know better if I was advised to do compression test first before spent 10K. Either way I HIGHLY RECOMMEND doing a compression test before anybody spends 10K otherwise it could cost you like me another 10K to fix.

After the supercharger was broke in, the second time I was driving the car the it went in limp mode. The check engine light and traction control lights came and would not reset. I had the OBD code read and it said P0307 that means misfire in cylinder 7. Then I had it towed back to the shop and ran a compression test which confirmed cylinder 7 was not holding compression and looking like a the piston failed. Its going to be taken apart tomorrow and I will know more then about the failure.

Damn, that sucks! Thanks for the update though. Curious as to what you'll find out.

Did Rafi chime in as to his thoughts on this failure? The only cases here on CL that I've heard of someone blowing something in their motor was from running too much nitrous (like a 200 shot or something). The 6-7 psi that the Rotrex produces isn't that much, but wonder if this is a condition of boost coupled with a 11.8:1 compression?

DAAAAAMMMM!!! this blows to hear such an amazing engine going out like that. to me sounds like low compression in one cylinder usually indicates a bad exhaust valve.

Any updates? The blown engine is kind of worrisome and if the OP does not object, I don't see why this information shouldn't be shared by another member who had the SC installed. This thread is about SC install, so any experience from other members is valuable, don't you think?

This thread is for all of you. As long as we keep it on topic (supercharger), I'm good.

I second this ^^^^^^^. i would like to know what failed. because i've spoken to Rafi before about the supercharger and he states that they have been running their Supercharger since they first came up with their prototype and now are using their production line supercharger and they have multiple track days with hundreds of miles already on their system and yet to encounter any hiccups with their setup. so i'm eager to find out if this is due to failure to maintain the engine and car at its due interval service schedule, before the supercharger was installed. or a self install failure. I'm looking to do this install sometime in the fall or next year and i might just take the car to have Rafi to have them install the system for me.

Sorry, I didn't update you guys sooner been very busy at work so I can pay for all of this. Anyway all the drivers side pistons were found with cracks in them. Pics show cracked portion of the ringland on pistons. Had a leak test on engine before disassembly and found leak of 20%-40% on the drivers side. The block is now being honed at machine shop. Next step will be ordering custom forged pistons.
