Rick, thanks for posting this. Thats the loudest I have heard personally.

 

Eric,

It seems slightly louder on video than in person, but it was pretty loud.

??

Is that noise with the Comp Cams Phase limiters?

 

The comp phaser limiters would still allow this to happen. It may not be as loud, but still would result in uncontrollable cam timing and possibly major damage...

 

Hey Andy, what cams do you recommend for a 3-valve Whipple set up? Heads are stock and I'm looking for the old school sound and some good mid/upper gains. What's available and what's in the works?

 

we are working on our own cams, but are limited by the available grinds.


Believe it or not we use the 127300 cams alot, while they have very minimal lope and are technically stated for NA not boost, they work GREAT w/ a whipple.

 

It seems like cams are really just getting cranked up for 3-valves. I think I'll be patient and hold out a while.

 

I did learn something I didn't know about the limiters. They are designed for the cams that keep the stock valvesprings. If you have stock valve springs, I don't see there to be any need for limiters. What am I missing?

The VCT issue is caused by aftermarket valvesprings.

 

This is our gripe here... Comp has not addressed the real issue with the VCT... Phaser failure, sure it might POSSIBLY save an engine when the phaser fails, but really maybe 5% of engines out there have enough PTV that phaser failure wouldn't crash a valve by limiting the range to 20*. Then you still have the issue of a failed phaser that needs to be fixed.

People will always try to eek out every drop of power they can, but in my opinion keeping the phasers unlocked on a modified application is just waiting for trouble...

 

With the Comp cams that require springs what has happened with engines that utilize the phase limiters? Is it true that the added friction from the heavy springs have caused problems with the cams ability to rotate in relation to the crankshaft during cam phase changes?

 

Yes, thats the problem, and limiters do not fix the problem.

 

That's interesting. As much as I'm ready to make the move on cams I'm really thinking a few more things need to be sorted out for the 3-valves.

 

Does that happen on ALL phasers or only certain versions/production run?

I guess I'll find out soon enough.

 

Crap, I hope MickeySaleens phasers don't fail. I'm almost set on the SPR Stage 2 cams. I wonder if the phaser lockouts result in lost power???

 

Confused....cant see the link to the vid.

Thanks got it.

I have the lockouts on my car but was under the impression that they reduce power quite a bit. Can anyone confirm this?

 

I have a set of Comp cams "Mutha Thumpers" for sale, plus lockouts- $550.

 

Why are you getting rid of them. Did you have problems with noise?

 

Thanks for the reply - I have BBR stage II and my car is n/a
