Roger's Z has been under the R&D operating table and the results are awesome.

We took some time to verify the results of a few combinations and have come up with a very wicked, yet daily driver friendly combo.

Special thanks to Carlos at Vette Air for his camshaft.....nice

The graph below is the final numbers and it is in street trim. Final A/F was 12.4 -12.6 with max timing at 22°

The final configuration consists of RPM Heads, Carlos Cam, Callaway Honker, RPM Ported Intake & RPM Ported TB.

Solid N/A combination

Darn good numbers!

What was the stock starting point?

ayousef

only those mods? thats like the best ive seen for NA, and I am assuming that is a mild cam??

Stingray23

can you say torque?

0C_Williams@RPM

It's been awhile and when the owner will chimes in here he'll know.

I believe that the car was 450 stock, 480 headers/air intake, 498 headers/air intake/ported intake manifold.

These mods reflect the improvements of porting the heads, a much bigger cam, a cold air intake and a ported TB.

I've seen several cars make similar power with similar attention to detail and specs. You can't just point a finger at a cam catalog or guess.

Thanks,

Charlie

No, I don't consider the cam to be mild but on the same note, it's not crazy wild, either.

I would certainly characterize this cam as "lopey" but very much a streetable cam.


Thanks,

Charlie

0C_Williams@RPM

thanks....it pulls very well at all speeds

Thanks Charlie and wow, you did it again!

Look at that torque curve and power output...can you say power under the curve and "solid tuning" parameters considering the crappy CA gas and weather?

Yes, this cam lopes like a 427 should and it is VERY streetable. Folks, those days of big cams and no drivability are OVER!

Any capable tuner in the country can install this cam and tune it to drive like a cream puff. If you live in California, simply contact/visit Charlie; take advantage of his tuning offer, knowledge of this cam and workmanship prowess.

Many guys in Texas are well aware of this cam capabilities, drivability and beyond. Now it is time for the rest of the country to learn...thanks again Charlie

Stellar results considering the low timing and rich final A/F

Simply awesome Charlie...I'm on vacation on the east coast with my sons...I will give you a call when I get home Tuesday...

Nice gain, but what causes the big power drop at 6700 rpm?

cbgpe

Looked over the results and wondered are these RWHP or engine dyno hp?

That is the same cam that SW used in his car and he told me it was very drivable and made similar numbers in his car. Hes tried several iterations of cams in the two different Zs that he has had and is very happy with Carlos cam

I am very happy to say that I am the owner of this car. This is by no means a small cam. This is a wicked cam that has that great "hot rod" lope that sounds downright nasty at idle...Charlie's legendary tuning skills along with his expertise at head porting and engine building in general produced a combination that makes this cam very streetable, yet my car pulls like a freight train when the gas pedal is mashed. Charlie spend considerable time in dialing the tuning in just right. As a result, there is absolutely no low rpm surging that is commonly seen in big cams. I highly recommend this cam to everyone who wants to see significant gains in horsepower and torque without going the blower route.

I would also like to give a very special thanks to Carlos at Vette-Air for recommending this cam. I believe that Carlos has this same cam in his personal car that ran in the 9's in the quarter mile. Correct me if I am wrong on this Carlos.

You are right Mr. Wong, this is the same cam found in one of SW's Z06.

This cam down right makes power w/o sacrificing drivability and having to rev the motor sky high...power under curve baby!


Yes Roger, we tested this cam on my car and and many other cars for that matter. I ran high 9's w/o a cam at the track (oficial); cammed mid 9's are not officially recorded (no track)...G-tech pro tested only.

A new nastier cam is currently being tested on my car with bone stock heads seeing how it behaves...this cam is called Lucifer. Intial testing with ported heads has shown that this cam is downright wicked...more to come, soon!

Thanks,
Carlos

PS, every cam we sell comes with its individual "cam doctor" spec sheet. That's right, our cams are cam doctor so you know you are getting the real deal and not some off the shelf run of the mill piece.

tjwong

Carlos, that is great because as any reputable tuner knows that when one installs a cam and to insure its in properly one degrees it to assure that. But without a cam card that is impossible to do. Some suppliers of these "custom cams" won't supply a cam card and say "just stick it in straight up" Jeez how many cams have you found that isn't ground quite right? I would want to know, and I am sure you would as well!

0Myhardtop

That is an excellent point Mr. Wong!

Remember, I've been on the other side of the fence; I hate it when I couldn't get cam numbers and was at the mercy of the vendors.

Folks, if you buy a cam from me [Vette-Air], you will get a cam doctor spec sheet that has EVERYTHING you or your installer needs. We don't play games...we make power!

Oh yeah, our QM 600 cam is $399.95/ with spring kit is $699.95! You see, no vette tax!
Thanks,
Carlos

I never got a cam card with my builder and it annoys the heck out of me. feel like designing me a custom solid roller for a measly LT4 c4 ?

BTW awesome #s from that cam and setup.
