You experts are wrong on the LS3/L92 cams...

[wkmcd]

I've been sitting on this post over on CF and forcing myself not to respond but he finally raised the level of BS high enough I couldn't take it anymore,


"Huge cams dont work so well and would require you to reagin piston/valve clearance by reducing your compression. The biggest thing that fights these heads is tight lobe separations. If you have less than 114 it isnt a great match but can work ok. In addition, the 1 7/8 headers will only compound the low TQ issues associated with big cams and these heads."

This was in direct response to someone using the same cam I took out of my car that worked pretty damn well.

What do you expect from corvette owners:icon_bigg

[SStrokerAce]

Sent you a little help Kevin....

BTW we also know that those heads aren't very compression friendly as well.

Thanks Bret....Between this guy and England Green with his "named" cams CF is more uneducated than LS1toke. CF really should stick with the "What color mats" questions..:strokin:

"He" is just not credible on most topics IMO.

*GASP*

You don't think that names like Whiplash, Godzilla, and Bunny make more power than everyone else's named cams? I'll even include myself in that mix since I have a named cam. :D

Then you will never do business with East Coast Supercharging (ECS) or any of the other leading Corvette Tuners in the United States.

ECS has more 9 second Corvette street cars running their custom proprietary cams than anyone else, BTW.

We protect our R&D and intellectual property. If you have a problem with that, you do not have to buy the cams.

While you guys are over there infiltrating, check out this one. I think it's post number 11?
Now we're into TFSs making 535 on 6.0s. He says it like it nothing. LOL
Also second mention of 12:1 comp. I guess that's his magic number.

No, no...the magic number is the 8.7 DCR that the 93 octane wanted to see. :D

I corrected the guy who said he'd didn't know if anyone CNC's the L92 heads and hadn't seen a bild using them. He's a little smarter now.:moon[1]:

You can do it but you can't run more than 24 degrees on lead. Don't ask me how I know. Not the best for making power with L92/LS3 heads. They LOVE timing around 30 degrees.

Kevin, that's Richards.... some changes here and there and they might like less... but that still doesn't make then less sensitive to knock, actually the exact opposite!

This guy is really stuck on the 12:1 CR like it's the magic key to make power with any setup. I know CR can make power but if you mainly run 93 in your car at what point are you taking a step backwards because of being limited on the amount of timing you can run? I have read about motors with less CR making as much if not more HP because they have the ability to run more timing.

[SStrokerAce]

Depends on the motor... but I've always found it's better to be able to give it all the timing it NEEDS (not more) without knock, rather than more compression and less timing.

That makes more sense to me!

As far as the motor I was talking about a 12:1CR setup compared to say a 10:8 or a 11:2 setup running on 93 octane. I would think that the lower CR setups could make just about the same if not more HP than the higher CR because I think 12:1 CR would be limited by timing it could run on 93.

Obviously I am no expert but that is just my understanding of it.

[SStrokerAce]

You basically run as much compression as you can before it becomes a problem that limits the timing you run. I'd rather have 11:1 than 10:1 or 12:1 because it's the best BALANCE.

Bingo.

I get so sick of "How much comp. can I run??"

Nobody ever asks "How much should I run??"

That's about it in a nutshell. I think I got it pretty well figured out, after doing 2 or 3 of them. Most of the LSs will ALWAYS run better, make more power, and be more tune-able with about 11.5:1 as opposed to 12:1. On pump gas that is.
Kevin's isn't the only one we've dropped compression and made more power with.
Also, as Bret stated earlier, there is a point were you have given a motor all it needs as opposed to how much it will take. Usually there's about 3-4 degrees worth where it either won't make any more before ping, or makes very little diff.
The lower the compression, the wider this window is.
The low compression L92/6.0s, now they take an ass load of timing, and keep making more power as you pour the coals to em.

When I saw this I had to laugh. Have you ever seen any car come out of his shop that has made any power?

I can tell you about some cars that came in running perfect and when they left they were in a bucket.
