I think Jerry sees your point. I think he believes you are blowing it out of proportion. Does anyone ever bash HKS for not tapped the hole in the end of the cam? Seems far more severe than simply not being supplied with the correct bolt. maybe you should just make it clear to your customers you may have to charge more to install cams that dont self install?

 

We have used quite a few sets of Comp Cams (custom ground) over the last few months and have had ZERO issues with any of them.

 

If you think that is acceptable, please don't manufacture any parts and sell to the public. To have to do all that is total BS.

 

Kinda hard to argue with this.....

 

Splicing wiring to install a wideband brain has nothing to do with an expectation of having to mutilate parts that are designed to go inside of a motor because they don't come properly machined from the factory. We're not talking about bending an exhaust hangar to make it fit better under the car - we're talking about cams, a one of the most critical engine components. If a cam or its hardware is defective, it could lead to valves dropping and making contact with pistons and essentially trashing the motor.

As to my experience, I'm no pro engine builder, but I've participated in 3 or 4 builds including a DOHC and OHV V8's. And if we ever encountered an important part, such as a camshaft, that was flawed we wouldn't use it. And keep in mind - these were our own cars, where there would be nobody to blame but us if something was installed wrong. I would be twice as cautious if it were someone else's car that I was being paid to work on, which is exactly the kind of caution that TTP has demonstrated by warning us all about Compcams. And if you'll notice, TTP's warnings have been seconded by at least two other vendors.

 

did you read all the posts? i'm saying it is not acceptable to make a part like that. what i am saying is, making a bolt fit in a hole isn't rocket science, and as such is something your average mechanic can overcome. so IF you buy a product that isn't quite perfect, someone who knows what they are doing can make it work.

 

and if you'll notice, i also said that it was a problem. i said why would you buy comp cams when you can get HKS or GSC cams which fit with modification.

HOWEVER, it IS possible to shorten a bolt to make it fit. if TTP cannot or doesn't want to do that, it's not my problem, it's their customers problem. i only do work with my customer standing next to me watching me do the work ( i work out of my garage). and as such, if i encounter a problem, which does happen from time to time like the comp cams, we discuss it and because i am able to do pretty much everything (machine shop access) shortening a bolt is as simple as using a zip tie to hold back some wires. and having a pretty good understanding of how an engine works (ok, very good understanding...) i know that the bolt, if it needs to be shorted a few threads, will not hurt the engine, or how it functions. it holds a sensor for gods sake, its not holding the cam gear on.

remember, i'm not advocating comp cams, i'm just saying a decent shop wont be hindered by a bolt that is to long. and if you have any race car experience at all ,you will know **** like this comes up all the time and everything is custom, including bolt lengths.

 

Yes the bolt can be modified to fit. This is not the point. The point IS that comp cams is not competent enough to include a bolt that fits with their cams. For this reason I will never purchase any of their products ever again.

 

Well, it seems quite clear that it's a quality control issue as it happend some times but not all the time. The point a number of people are missing is that is shouldn't happen at all and once it has happened they should be able to make sure that it doesn't happen again. The fact that it has, seemingly quite repeatedly, does not give a good impression of the company.

Yes, they make cams. But if they are going to make cams and supply other parts with it also, they must make sure that it all the parts are correct for it. I mean, it's them who drilled and tapped the hole so there's no excuse for a wrong bolt. And it costs them just as much to send the right one as the wrong one and probably about $0.04 less for not tapping deep enough - the thing is the customer has paid for all that to be done right. It's just wrong to say that they make cams so anything else is not their problem.

Yes, I'm sure the fastener can be made to fit or a fastener can be found that fits. But if you need to do all that (find the right bolt yourself and/or cut the bolt etc.) then it should say so on their website or somewhere on the packaging so their customers know they will need to go out and buy whatever before the install.

Seems a shame because the cams they make are (as I said) probably as good as any out there. To be let down by such a minor issue is silly and I hope they can fix it soon. Their cams are what, $370 a piece? If you buy the bolts in bulk, you can probably get them for close to $0.5 if not less. And I doubt it would be the end of the earth if they just tapped that hols say 1-1.5mm deeper than they need to just in case.

I think this thread is useful not because it slags off a particular company but highlights a problem (some) people have had and that's no bad thing.

 

I'm an idiot...

We had a couple cams where the cam angle sensor bolt was either too long or too loose.

The issue with the bent valve car was actually the other end of the cam, on the cam gear side. The bolt hole was a bit too large, we assume, as the bolt was able to back itself out within a matter of hours, and it was torqued down properly.

I was confusing two different issues. The cam angle side has been an issue for us before, but we worked around it by using a different bolt. The bent valves were due to a hole tapped too large.

Sorry, I got it bass ackwards.

the whole point these guys are trying to get accross is if they are going to have different size threads & lengths on there cams supply a bolt that will solve the problem..

 

Still happy with my comp 280's.Turbotrix still sells them and recommends them. i wonder how many sets they installed over the last yr.

if i had another evo, i'd buy another set.

 

Damn Scotty...

You're a pretty bitter man, you know that?

Most of your posts are intelligent and very beneficial to the community and then there are posts like these.

It's not the end of the world man. Take a deep breath and relax a little.

 

whats this gotta do with the evo 9 cams? I don't drive a evo 9. Why u tryin to rag on turbotrix. Don't be so bitter.


And why are u not surprised i like them. My car makes more power then some of my friends with the same set-up, just a difference in cams.

 

Wow, this sucks. Comp cams makes great products for other engines, mostly V8 stuff of course.... and the guys who have 'em on their cars seem to love them.

I hope they have this sorted out by the time I go to buy cams, I was hoping to use their 280's
