C5 Corvette - I/H/E - HP Tuners Dyno Tune

[top dead center]

This Corvette belongs to Kyle of Spartanburg. After installing new headers and exhaust, he brought it in for a tune on HP Tuners.

Kyles new LG Motorsports headers had slip on, high flow Catilytic Converters, but Kyle decided that those would be better replaced with straight 3" pipes. In an effort to keep the exhaust serviceable, we flared 2 sections of 3" pipe to fit into the headers, using the supplied clamps. This will make reinstalling the cats a simple task later down the road, if it's ever needed.



After the exhaust mods were finished, Kyles Corvette went on the rollers.

Here is the setup:

2004 Corvette Z06
LS6 / T56

Vararam VR-1B Intake
LG Motorsports Long Tube Headers
Cat Delete Pipes
3" Exhaust

Tuned on HP Tuners

The blue chart is the baseline pull, untuned. The red chart is the tuned chart.

this might help you in advertising 'results' in the V8 world:
H= Heads, ie non stock heads, not headers
If I miss you stating that this was a Heads car I apologize.
I= Intake, not a Cold Air Intake, we use CAI to indicate that. FAST is about the only Intake (I) people use on the LSx based cars.

So how does HP and TQ cross at 2 different RPM's on the same plot? I know since the scales are different it won't be at 5252, but they should be at the same point for 2 runs.

Scales not the same, notice the Left side is a different scale than the right. It happens. but he did say different graphs would be posted later....

New chart posted.

Thanks for sharing your unlimited acronym knowledge. I assumed that most people were capable of reading the mod list, thus understanding further the extent of the modifications, instead of drawing a conclusion from the title.

We use the I/H/E to designate CAI/Headers/Exhaust, as we do in all of our postings.

We post a few of our 'results' not only to advertise, but to start dialogue on the forums. We appreciate your input!

When I see "H" and "I"; I would expect something over 400 to the wheels which is why I looked a few times at the graph and then realized it was just exhaust mods and a CAI.

I know it will cross at a different point if the scales are off, but for 2 pulls it should cross at the same point still which it didn't.

Which graph are you looking at? The one I see has both runs crossing at 5,250 rpms...

What in the world happend to the torque up top?

Already posted up a fixed one.

Josh I was wondering the same thing.

It's an LSX (mainly excel in low-mid end power/torque). This setup would benefit greatly from an Intake Manifold and a Cam. Then we pick up more power and perhaps delay the point at which power/torque falls on it's face.
