I have HKS cam gears, set to the positions recomended by silver surfer before he left evolutionm, and with the bolts held in with red "locktight". I wanted Dave Buschur to play with the cam gear settings on the dyno, but it seems that some of the locktight got between the parts of the cam gear that actually move, and they may as well be welded in place.... they are NEVER comming lose

so hks are good? ive heard alot of stuff about cam gears slipping on other cars/motor setups but havent read to much on evom...

What would most recommend...

 

HKS cam gears running 272s installed by AtlanticMotorSports perfectly, no issues at all maybe around 20K miles or so. And that's the TRUTH!

 

anyone use aem"s?????

 

Mine slipped with lock tight. Don't know why maybe because i was enjoying the cams and driving like a jerk but they slipped after tuning my car after the dyno, on the way home. Just one slipped. I would never run gears again and just stick with factory settings and lager cams. Also my gears were slightly larger then the factory gears and made noise, I switch back to the stock ones when found out that my cam gear slipped.


IMHO

 

I have noticed that it is never the persons fault just the poor cam gears fault.

 

I did not use them on my car but I did install a few sets on other peoples cars and I really like those over any other that I have installed or used my self. IMHO

 

oh who would admit that LOL

 

Yours were slightly larger than factory? That doesn't make sense, if they were larger, they would spin slower than needed, and never stay in time.

I'm assuming when you say larger, you mean the O.D. was bigger?

 

I don't know what to tell you but after taking them off I put them back to back with the stock ones and just slightly larger. Tooth count was the same go figure.

 

agreed +1

 

I have Vishnu cam gears 40k without issue. I've moved them around, too. Great pieces.

 

Yes but it wasn't on my evo it was on my 300zx a few years back.

Improper machining was actually the casue of the failure

 

I have seen a set of fidenza's slip. dont know who installed them, just saw the aftermath.

 

I've seen several cases of cam gears slipping in other applications of a few different manufacturers... a couple user error... not all. What most forget is they are a "race part", and not a 100k OE part. I don't/won't run them on anything short of a weekend race car, and even that is debatable.

Since I've not personally seen them slip in an Evo application (like it makes a difference), I didn't vote.
