And, unfortunatley, not my stock turbo. THat is, you're not using my stock turbo

 

an upgraded tme w/ the wr wheel

 

I know that

I meant, you aren't using the turbo I sold to you

 

Guys, could we please try and keep this on topic and free of non-thread-related posts? There are a lot of people subscribed to this particular thread, and I'm sure they would appreciate it remaining as fat free as possible.

Thanks, in advance, for your cooperation.

 

Pd1, please stick it out with these cams. There are a lot of people depending on you figuring this out including myself. I really want to have tuning technologies install these for me, but not until your problems are solved. I just ave a really hard time believing that the cams could be ground wrong, but ultimately I really don't know.

 

I'll do my very best, dsevo. If I'm anything, I'm stubborn. However, I must admit, this has been a trying ordeal thus far. Hopefully, we'll get this figured out and running well very soon.

 

It doesn't help at the moment, but Timzcat said it... there should be NO change in mechanical noise by placing the gears to 0,0. That in it's self is a clue things are not in a good way. Again, hope you find the culprit, and get things worked out!

 

I can't think of any reason that valvetrain noise would change with cam timing even if the cams were ground wrong, unless you actually had light piston to valve contact.

Could there possibly be valve damage and compression loss causing the power loss? Maybe a quick compression check would be worth the 30 minutes that it takes?

 

No one ever answered whether or not the lifters were bled.Can you confirm this.
I would try the stock gears as previously mentioned.Thats alot easier then replacing the cams.

 

I didn't want to bring that up and jinx him... however, I'd think symptoms would be far more sever.

 

You're right, it does seem strange. However, I can verify that the "valvetrain noise" did not cause the loss of power evidenced by the dyno charts. How can I be so sure? Well, the dyno runs were made *prior* to the adjustment of the gears to 0in/0ex...which caused the noise. Moreover, RoadRace Engineering claims that they've never seen a situation where a piston kissed valves and didn't break the valves. Apparently, the Evo valves are hollow and sodium-filled. Because of this, they are much more prone to breakage than bends.

With reference to the lifter bleeding, no, they were not. I asked TT about this twice before the install, and they assured me that with their method, it is not necessary. Perhaps Tuning Technologies could chime in if anyone needs a better explanation. It seems logical to me, though, that there isn't a lifter issue because the valvetrain is totally silent now, and only made noise with those cam gears set to 0/0. As TT says, the lifters are seeing the same load now as they did at 0/0.

Last minute scheduling is going to prevent us from solving this in Colton on Saturday. I may double-check a few things (TDC) this weekend and see if I can gain any insight. Right now, I'm penciled in to be at TT on Tuesday -- assuming I can play hookie from work.

 

I am sure you have already read it, but in another thread about problems with these cams, a guy said he had 7 lifters collapse with the install of these cams. After he replaced the lifters, everything was fine. If you haven't seen the thread the link is:

The post is the very last one. I think I will go ahaead and have new lifters put in at the same time I have my cams installed.

 

They bend , trust me !

I had timing jump b/c of a wreck and bent all 16 valves

 

Just the exhaust valves are hollow sodium-filled.

 

Okay. We're going to get to the bottom of this.

I've made arrangements with Tuning Technologies to leave my car with them on Wednesday until I return from a business trip on the 19th. This will afford them plenty of time to do all sorts of checks, and fix whatever may be wrong. They will have a known-good set of Revolvers on hand, and will be able to solve the mystery and have the car running like it's supposed to by the time I get home. We'll keep in touch during my trip, and I'll keep you posted on the progress.
