man what wrong with this cams{t2} I broke a set of then when I miss a gear and it when from 3rd to second but my friend broke a set at the dyno at low boost now i'm thinking of take the set that they replace when I broke mine what set u guy think that I won't have this problem

 

how exactly do you break a cam ? got any pics because your entire head wud have to get f--ked serverly in the process

 

the one in my car ek9 with a b18c1 with 580whp it was going down the track and I down shift from 3rd to 2nd

 

an you broke a cam without messing up the whole cylinder head ?

 

no it bend 8 valve which they hit all four piston and the crank took the load

 

oooooh ok cause you stated that you BROKE the CAM

 

Ek9t72 perhaps you should slow down on the keyboard so we can actually discern what the hell you are trying to say

after about 10 passes on the dyno,and fixing a few stupid problems. my car finally started to clean up,we were about half way into forth gear and bang she shut down. it actually sound like we blew off a ic pipe,so we checked everything went to start her up and she would not turn over. comp test showed no comp in cylinder 4,3,2 but #1 was fine. so my buddy went to touch the cam gear and could almost pull it out of the head. both crower cams were broken in about three places,NEVER SEEN IT BEFORE IN MY LIFE! pics up soon,any insight on why this would happen? i'm kind of thinking crower wound know!

was everything in the head torqued down to the PRODUCTS manufactures specs ? also were your valves adjusted properly ? from the sound of it maybe something like a rocker, spring, or valve wasnt secure and when you hit mid way into the rpms the nightmare started. also how were the spark plugs and A/F's

 

everything was were it was supposed to be,a friend just told me the same cams broke on his car. so i'll call crower tomorrow

 

wow thats not like a crower product to do that who installed the cams ? also were they 402, 403, 404, or 405

the cams are about two years old and were used only in this car. i am very sure these cams were installed correctly,crower cams 63401 T2.

check out the pics bro!

 

from the looks of things you probably had something fail into the engine to cause that OR installers error we hate to admit it but it happens sometimes to everyone also was that cam cold chilled ??? ( not right name) or cryo-treated

 

might have been a bad core, they've been known to overlook a few those in QC.

If you want a custom ground camshaft, try bulletcams.com.

We do everything.

are you asking if they were cryo'd as in that being a bad thing? Idk anything about how cams react to being cryo'd, but from what i've read, the treatment is much like shot peening or aneeling metal and realigns the molecules and strengthens the metal to some degree. Please correct me if i'm wrong with that...<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by t . b o z &raquo;</TD></TR><TR><TD CLASS="quote">might have been a bad core, they've been known to overlook a few those in QC.

what kinda prices do you guys offer? I'll need a set of cams for a b16 for soon and have no idea if i should go aftermarket or keep my gsr's....

This thread has pretty much turned me off from crower cams...that is ridiculous...

 

cryo treating is good its better than heat treating and more control. i was asking because it would require a TON of force to break a cryo treated cam

O ok, that's what i figured you were saying
I'm going to cryo treat quite of bit of stuff in my build just for the extra ease of mind. I was shocked when i saw how chepa it is.

dont think so bro,this head was on two setups and never had a problem. both setups were over 500hp. this is not the first time this has happened with crower cams.
