Schoolboy Error - 7a Cam disaster!

[merlin's S4]

I've had a 7a exhaust cam lying around for years and had finally reached the time when I was going to fit it today as part of my rebuild. However in a split second my intentions were struck a horrid blow! I managed to knock the cam off the bench, onto the concrete floor and it broke in two!! Looks like I'll be sticking with the standard cam afterall. Gutted...

Wow not good, i've heard of people damaging the gear on the end of the inlet but never seen one like this. If your after another pm spink as he has one afaik.

Best thing for it IMO

I was installing an RS2 exhaust cam yesterday in my otherwise completely RS2'd AAN (93 S4) and that was my biggest fear: dropping the cam on the concrete floor. I can imagine how bad you feel. Good news: it was a 7A cam - more of those around.

i got one a bit like that. mine broke in the engine though.

parts of me agree with jamo others are not sure yet. back to the pursuit of 7a goodness...somewhere over the rainbow

[volcano rs]

a bit of super glue should fix that

Seen them snap when people bounce them of the limiter as the caps make their way loose.

On the other front on a stock head no real gains on 7A exhaust on a reworked head I've got dyno figs before and after showing quicker spool and more power across revrange on a K24

it just snapped. i have no rev limiter.

presume weak. no engine damage. one valve stuck open.

lucky, lucky.

i think there is minimal if anything on a 7a upto 500hp. i think its also a proven thing. the aby's pull better than the 7a's
