Your a smart guy... you can figure it out for yourself.
nothing that has been done different in the past with other turbo cars.

I ran 114mph but only 13.3 because the clutch was also slipping off the line when I dropped it. I barely had any miles on it. under 8000 miles

I think it's great that they are making all this power, but they are leaving far too many questions unanswered IMO. I wan't to see a datalogs for the IAT2 temps, MAF, and the torque figures on the dyno graphs personally. Not saying it's not possible, but I would definitely like the see some more data out of pure curiosity.

agreed

the IAT2s had to have been be fairly low though with crazy pulls like that

The MAF is custom, numbers wouldn't mean much to you.
IAT was 109 at 22 psi exiting the front mount. I'm not sure yet on post liquid IC. We've done nearly 100 pulls with various configurations and on different days with different ambient temps. Our goals are to learn more about the car, tuning and our kit, show what the potential of our kit is, show that we are the best at what we do, show that the torque and power curves are unmatched by other power adders, and prove that customers cars will leave here safely because we will have them detuned a long ways from our 500WHP goal.

yeah but didn't you get brake fluid or something on yours?

I had thought I did but there was no evidence of it. Just trying to look out for others, that is all.

Exedy is only rated at 280ft/lb on slicks which is crazy. And the support sucks from them. They don't answer emails and don't offer replacement discs within 2 months. So I went Spec.

Someone is ninja editing lol

increadible.

congratz on a great kit guys.

Nice numbers.

Any chance we will see a full dyno pull or maybe an HPTuners log of a run? Would be an interesting comparison to a pure turbo setup.

x2 on that. Still have a stock clutch on mine, 23 psi from the TVS and its never had a problem.

Which just proves the stock clutch is capable of more than most any one is giving it. Just depends on how you drive the car.

There are lots of full pull runs posted on the site. Our power curves look a million times better than turbo only setups where you have a little peak power for bragging rights at the top of the rpm band. Our kit gives double the power down low and a smooth power band from start to finish. Again, many examples are posted on the site.

We are having trouble with hpt logs giving us all the data. Our custom MAF does not have temp reading and it's making the scanner not show IAT. What pid do we need to add to log the post intake IC IATs?

If you are still using the stock intake manifold the stock MAP sensor is actually a TMAP which has the ability to show intake air temp after the blower before it reaches the head if you still have the stock MAP in the same location. The PID should read IAT2.

The other IAT is built into the MAF. A FSM should show you the two wires that are IAT specific for relocation purposes if you would want to relocate it.

I'll look for the other dynos. Thanks again.
