We recently did a little testing of the Haltech intake using a customer's 2006 Z06.



UPDATE: We finished the tune on the car and these are the final before/after results using SAE correction on all runs:


We started with a baseline pull in completely stock form with the stock tune. This is the blue curve.

Then we installed the Haltech intake to see what it would do without tuning. The intake gained 12whp over the stock baseline. This is the green curve.

Finally, I performed a custom tune on the car using HP Tuners. After a couple hours of fine tuning everything, we ended up with an additional 18whp for a total gain of 30whp or 7% over stock. This is the pink curve on the chart

This car will soon be getting headers and a cam as well and we will document the gains from each mod individually.

Hopefully you guys find this sort of data interesting or at least mildly entertaining .


Thanks

Are these raw numbers? Or have they been adjusted for changing ambient temps throughout the day?

 

These numbers are uncorrected but the temps were pretty consistent. I can post up the SAE corrected charts tomorrow.

Yes. Love info like this. Please keep doing it. Thanks!

 

Thanks for taking the time to do back to back testing.

 

Hey Ed if you want to be entertained, install and compare the Calloway Honker.

These are great posts please keep them coming!!

 

Thanks guys we'll definitely keep these up!

411 seems awfully low for a stock Z06 - does your dyno read relatively low? Other dyno runs on this forum seem to show in the 430's to mid 440's for a stock C6 Z06.

Any idea why so low? Thanks.

 

As Mike mentioned, we have the dyno calibrated to read like a lower reading Mustang dyno as apposed to a dynojet. Generally our dyno will read 10-15% lower than a dynojet or dynapak.

There is a reason I calibrated the dyno to read this way. When I started tuning back in College, I was doing mostly road tuning, so I developed my own nice road dyno software. This program used RPM/Time data from a log along with gearing, tire size, weight, and aero parameters to calculate your actual on-road acceleration and derive the HP and torque needed to achieve that acceleration. This gave me a very consistent and repeatable HP/torque curve just like a chassis dyno. What I found really interesting was that the numbers produced from my software were always within 2-3whp of a Mustang dyno. Since my numbers were based on real world accelerations and some very basic physics, I was impressed that the Mustang dynos were nearly dead on with these results. Ever since, I have been much more used to working with such dynos rather than Dynojets and Dynapaks which tend to read about 15% higher.

Remember, however, dynos are just tools and what's really important are the before/after gains not the absolute number. Our dyno gives very consistent readings which makes it a great tool for comparing results. It can just be a bit tough to explain to some people why the numbers might be lower than they'd expect.

Thanks

Mike/Ed,
Thanks for the explanation.

Based on the 10 to 15% plus up required to bring it in line with other dynos, it would appear you had a real sceamer for a stock Z06.

411 plus 10-15% = 452-472, pretty healthy stock engine!

But I get your point - it is the delta after the changes that matters.

 

Just updated the first post with the final tuned results. I also changed the graph over to SAE weather correction since the final pulls were done on a different day.

Thanks

Not to get too off topic but did you guys ever finish tuning Mikes Z06 after the MF103 he did? I know he gained 6whp just putting it on but what about after retune?

 

We've been very busy and haven't had time to tune his car yet... I'll post results as soon as we do.

-- Ed

 

A little update on this car... he ran 11.7 @ 126mph!

-- Ed

 

nope it was 11.5 @ 127?

 

That was Mike's car which did about 455whp. The car referenced in this thread is a customer's car and he ran an 11.7 @ 126mph yesterday.

-- Ed

 

Yup, 11.743 @ 126.01 MPH, Infineon Raceway. Wasn't my best 60', either... I actually had a 1.975 (Invos) when I forgot to take TC off.

The car runs GREAT!

 

how did mike only make 7whp more with Ported Intake Manifold and Ported Heads over just an Intake/Tune car?
