Picked up my 2001 ZO6 Friday After CAM package install at DYNOTECH ENGINEERING,FORT WAYNE IN.Phil and Jenny are superb .They listened very carefully at what i wanted out of my car as far as performance. and I am very well pleased with the outcome.Phil did a before and after Dyno with tune.while i was there.both times.I would post the HP &TQ# from the Dyno but there seems to be a few people on the Forum,doubt that the cam size Phil put in would not make the HP # he said. They did .I saw with my own eyes the dyno runs.I would highly recommend their shop to anyone who wants to upgrade their corvettes performance.

 

Yes... from Canada ...been there and seen the place...great people...and the work they do..fantastic.

Congrats and kudos to Phil & Jenny...

 

Glad to hear that you had a good experience and feel that you got the value for each dollar that you spent.

Please post the dyno sheet with the base line and where you ended up. This way, we can see just how much power you gained, what the AFR is set at, etc.

In my opinion, dyno's mean nothing without knowing all of the factors involved. I have seen plenty of dyno sheets as has a lot others on this site where all kinds of dyno tricks are pulled in order to get a "big" number.

Enjoy your ride.

yeah i wanna see toooooooooooo!! dyno sheet dyno sheet!!!!!!!!!!

 

This is the dyno graph from this car~ before & after for those that have requested it via PM.

Here is the dyno data control for these runs:
Date: 3-21-07
Time: 5:45 pm
Ambient Temp: 76.79* F.
Barometer: 29.54 in./hg.
Water Vapor/Humidity: 36%
Correction Factor: SAE 1.00
Smooth: 0
Rollout: 44.19
Tire Press: 35 psi.
Engine Coolant: 184* F.
MAP @ WOT: 96.4 Kpa
AFR: 12.8:1

As we've said before many times, we're used to seeing this kind of power with our cam packages when these cars come in here already modified with the standard mods we commonly see on these cars- (headers, CAI,) and it's nothing magic or earth-shattering to see these repeatable power figures from other C5Z's we've built all over the USA for many people. Our cams are specifically ground to suit the application, not the other way around.

Additionally, observe how broad our powerband is with our packages, compared to what the peaky "big cam" cars have, where they are a torque slug until 4500+ RPM and have to be spun very hard to produce any sort of real, usable power...

Denny's car runs very well and if you ask him, the drivability is surperb, despite what others have stated or would have thought it would be with a package like this. Hopefully he'll chime in with his thoughts on the subject, now that he's had a chance to drive it a while since he's gotten it back.

There is *FAR* more to the design of an effective cam lobe for a given application than just the advertised numbers that everyone sees and it's the sum of *ALL* the components working well together in a well thought-out package that produces exceptional power, not just from any one single component alone...

Been there, done that and we'll repeat it all over again on another car as we've done in the past.

BTW- We don't play dyno games- not in the past, nor will we ever....period, as we have no use for that B.S. and anyone who knows us, knows that we are upstanding.

Phil -

Thanks for posting. Nice numbers.

Quick question - About the results of the whole package -From what I gather, this customer has headers, intake, your cam, and a tune. I take it you also installed the retainers, springs, seats, seals, and pushrods, which are all part of a upgrade cam package, but do not produce power (Outside of the cam). Thus, I am just trying to understand how your package differs from tuners out there. I guess I mean when you stated that it is a process of the all of the components working well together. For a cam only package, this seems to be getting the results of my friends LPE and Mallett H/C packages. I think that LPE is running a larget cam though, 229/242 .631/.631 @ 114 LSA.

wow!!!!!!! nice!!!!! very very nice flat power curve!!!!!!i hope my cam does that good! woohoo 224/228 581/588 14 lsa

did you post your cam card numbers? and do you know if they advaned the cam on the install?

 

76 HP from cam only? Was then tune on the 01 that bad to start with? 351 seems a little low for an 01 with headers but 427 on a cam only LS6 seems high. JMHO!!

 

1st. question: The car had the standard mods on it that we typically see when a C5 comes in here- as already stated in the text....nothing different or special.

When a customer comes to us looking for a specific performance upgrade, I spend a *LOT* of time with them on the phone collecting data on what they want from the car, drivability characteristics, traits, etc.; then grind them a camshaft based on that criteria and design it to be optimized with they already have. Far too many folks always *think* that "Bigger is Better", when in reality, it most certainly is not for a street car and that is why you see folks like Tony Mamo from AFR (amoung others) produce such outstanding power with relatively small modifications, compared to what others do with "bigger" parts, but then get poorer results.

*J.L. often followed this very philosophy when building his engines/packages and he consistantly kicked everyone's azz at a shootout time-and-time again with "smaller" parts, that always kept everyone scratching their heads.. I learned from his successess in that regard when I was employed there (LPE) and I'll never forget it...

None of this is magic, however, designing a good camshaft for a specific application does require a *lot* of fore-thought to accurately hit the nail on the head the first time. Lastly, there is a lot of power in a solid calibration also and as anyone knows, there are near limitless ways someone can tune a car the right or wrong way...


2nd. question: The stock car came in at the power level you see and the customer was standing right there in the dyno cell watching the entire pull. Our dyno rollers are calibrated for weight bi-annually and we have no reason to believe the software isn't accurate either, as we have the latest version Dynojet offers to date.

3rd question: No, we will not post a cam card.........

One last thing- We knew there would be nay-sayers, as there are in anything in life and we don't mind. (Denny included) That is why we took the time to show Denny the dyno runs, while he was right there in the dyno cell with us on the computer, a number of other C5Z's that had this similar package done to them that were similarly equipped as his car was. As I said, nothing magic....been there, done that.

Phil -

Thanks for your response. I understand about every tuners desire to satisfy their customers. Glad to see you are fitting that bill. The combination of the package outside of the cam seems to be normal mods. So, this one component, your custom grind cam, is putting out what H/C applications at LPE and Mallett are putting out with LS6 ported heads. But, who knows. That is what my question was from my post.

Take care.

Those are some good results. The only thing that would make it look better would be if you could adjust the axis of the graph so that they are equal and the torque curve and horsepower curve meet at 5250.

 

We don't change the axis locations of any our dyno reports manually, as that is done internally with the software as a "snap-to-fit" function, so the graph fits the screen properly. The less interface the dyno user has on the software measuring parameters of the program, the more accurate the run data often is- 5250 intersection not-withstanding.

i may have missed this somewhere but just out of curiosity was the duration more than 224 and was the lift over .600?

no cam card there

 

Rusty:

I believe the cam specs were 228-236 on a 113. Lift is a secret!!

 

was the lift over .600 ?

 

From another forum:
Cammin ZO6

--------------------------------------------------------------------------------

CAM size-228-236-113 lsa custom grind.Was asked to not give out lift #,I said i wouldnt.HP #427 RWHP-391 RWT.These # are with Kooks headers and Cam Pkg Phil suggested/

 

then i am gonna say they were over .600
