Hello fellow DC members. In my quest to squeeze out as much horsepower out of my 07 coupe as possible, I decided to let RevExtreme in Tampa Florida put in a cam and install a FAST intake for me. I already had 370+ at the wheels with headers, exhaust, tune, vararam, etc.
Kyle did the work for me and did a fabulous job- they got me 436RWHP and 398 torque. I was absolutely besides myself when I heard and drove it. Unbelievable! However, I had to leave for a 10 day trip the day after i got it back and only got to put 10 miles or so on it. I returned last monday and drove it an additional 40 or so miles, and on thursday, on my way to work, a very loud clanking sound suddenly rang out from under the engine. I was cruising at 50mph in 6th gear at about 1500rpms. I pulled over and had the car off within 30 seconds. Had it towed to RevExtreme, and within a few minutes, they showed me a titanium valve spring split in two- yep, these are the 918's model I found out after the fact that Comp Cam had been having lots of trouble with. We dont know what other collateral damage has been caused. They're pulling off the head tomorrow to check out the piston and other internal parts.
Has anyone had this problem with comp cam springs? and if so, I'd like to hear what happened to you, and also what I might expect in terms of additional damage that may be caused and how to proceed. Additionally, does anyone have recommendations on different valve springs that may be more reliiable? RevExtreme said that CompCam has apparently been handling these part failures well, covering replacement of all failed parts and parts damaged as a result of the failed valve spring and labor. This indeed better be the case. Needless to say, I'm heartbroken to have this nearly brand new vette, with only 3600 miles on it so severely damaged.
Any thoughts or feedback would be welcomed! Tim
