Baseline Dyno Pulls Katech Torquer
A couple of weeks back, the following modifications were made to my 2006 Z06 at just over 20K miles.
Katech Torquer 110 cam
WCCH Stage 2 cylinder heads
Ported stock intake manifold
Ported throttle body
Callaway Honker CAI.
Aside from a base tune to get it started and some street data logging, the car has had no other tuning to this time.
Anyway, to get a "baseline" dyno before the tuning is complete, it was put on the dynojet and two pulls made.
The car has the stock manifolds, and a bung has been placed for monitoring the A/F ratios.
As seen in the graph, the car is running a bit lean, min A/F ratio at 12.82, maximum at 13.51, and there is still some KR in the higher RPM ranges.
It will go back on the dyno after changes to the baseline tune are made, but I was curious at this point as I am sure others were as well.
I am very impressed with the torque numbers, even though this tune is not quite on yet.
Depending on what peak power numbers are when the tuning is finalized, I may or may not go with the headers.
At any rate, the dynograph is below. At this point, right after installing the mods, it is at 508.10 RWHP /474.95 RWTQ. Running it up to 6800 RPM.
This guy was around 529/493 with headers so we're getting there.

Looking forward to the tuned results Ricky!

I would go with lg 13/4 Header I know people say bigger is better but that's not true. You will be at 525 and 490 500 torque hopefully....
Im putting my Heads on no cam full port job with full exhaust Im hoping to be at 515 with no cam. I am at 480 plus 470torque. with tune and exhaust.

I bet with the tune fully dialed in, you are gonna be within about 15-20HP of the guy with headers... then the question becomes, is that amount of extra power worth the extra cost of headers

Good numbers Ricky. PRP is calling your name. I figure you are going to Gettysburg the end of the month. If my car is ready I may go with you and get tuned for my heads and then we can run them at PRP that weekend. We need seat time before MIR.

With the car making this kind of torque down low, without the tune even being completed yet, I'm hoping that I have enough tire in the Hoosiers I have now.
Not to mention the clutch.

Torquer 110 or 116?

I agree, very decent numbers especially since the tune is not all the way dialed in yet

He should make WELL over 525whp with headers. He has Ported heads, decent cam, ported intake/TB, Cai, and tune. Add headers and he should make atleast over 550whp

Wholeheartedly agree. I'm making 522/502 with the 110, AR headers, and a Halltech 103. No head work. I know he has more in there. Also, I specifically told my tuner (NicD working off the Loudpedal Motorsports dyno) that I wanted it kept fairly conservative as far as fuel ratio went.

I always thought that most of the benefit from head work came from milling the heads to increase compression.
Mine were only milled .009, but are ported.
I was hoping for around 520-525 on the stock manifolds. But you think if I get there, that I'm leaving 30 horses on the table without headers?

I would think you would make more or atleast that on stock manifolds, there's people on here with just a CA "Smogable cam" and Cai who have made 520-525whp. So I don't see why with heads, ported intake/TB, and headers you wouldn't be over 550+whp. That seems very typical for mild H/C Z06s

Next week we'll know how much milling the heads .030 and 1 7/8" headers without cats are worth.

That is where I'm looking to get mine.
mmmmyeah, it would be.....if the tune was complete.
But the A/F ratios are not optimized yet, in fact at least a point off, and there is still a bit of KR in the datalog taken during these pulls.
I really put this up here to get us off some of all of this head talk in here as of late, and actually had strong reservations putting this up before the tuning was complete.
Posting a dynograph up here without a full tune was risky, but I thought I'd do it anyway. What the hell.
But, we will be able to chart progress in going from here to the next step, a new calibration will be going in it in a few days, and the steps after that.

Whats "depressing" is how you think his numbers are low. The truth is the dyno numbers for the same combinations have continued to climb on this forum over the years. It won't be too long before a tune only gets you 600rwhp.
