Very nice! That combination will really wake up with some headers!

That's with headers, according to the Katech website.

Just for clarification, the 509rwhp chassis dyno sheet posted was for a car without headers.

I see your recipe includes an MSD intake did you guys test the before and after with this set up, curious if it was a difference maker, the pictures look like a stock cover on on the manifold not the MSD one.

Why do you run a 160 thermostat? Everyone knows they don't do anything and they are bad for your engine.

Yes. It makes a huge difference. The photos were taken before the intake was tested.

Anything you can share as to how much it added?

My car made similar horsepower as this one but I did have headers but no intake manifold.

Default Headers

No headers on this car explains the additional 30 ft-lbs torque for the website car, which listed headers.

That's more HP from a mild cam than what I've seen on here, so part of that increase must be the MSD intake manifold.

Oops, sorry, didn't see the 523 ft-lbs above. The website lists 533 ft-lbs, so looks like the headers were worth 10 ft-lbs.

I'm sorry for digging this thread up, but I'm curious if any testing has been done with this combination and long tubes. I love that it doesn't seem to lose much down low, but still pulls very well to 7,000+. Most cams seem to shift the curve way more to the right than this. Thank you for the information that you've posted!

The engine dyno test was done with dyno headers inititally to develop the camshaft. The final package was tested on the chassis dyno by the time the production MSD intake came out and that car was not equipped with headers. It made 509rwhp. We have not tested a car on the chassis dyno that has headers.

With headers and E85, another 40-50whp would be very possible then. That's incredible with a mild cam setup. Do you happen to have any videos of the idle? I'd like to keep the idle pretty tame to keep from burning up cats.

I'd like to see an idle video as well if it is available.

So, this LT1 cam sounds just like this Z06 at idle? I'm not sure I follow.

Sorry. Wrong videos. I'm pulled in too many directions today. Let me see if I can find the videos I was thinking of.

You don't have to run through yourself for a video. I'm basically just trying to find out if it's safe for cats. Don't want to dump too much fuel at idle and melt them.

All four cats have been on this car with this cam for about a year.

Here is the video.

Pretty good power with a pretty soft cam. I know there is lots of work on the C7's when doing heads and cam.... But is it ?!? A smarter choice to to a stroker when spending lots of cash ? Not bashing at all... I'm a guy that will spend $2,000.00 to get the last 5hp. My 15 A8 is still stock. I'll pull the trigger at some point. Waiting for the correct time.

Valid questions IMO. My 2015 A8 is stock except for a Trifecta tune, and I'm leaning towards the stroker route. I estimate the additional stroker cost over heads & cam is worth it for a street car that don't get beat on drag racing a lot, so long as a guy got the extra cash.

Thanks so much! I'm amazed by how mild the idle is, the car practically sounds stock. I think this is the perfect setup for me. I've been searching for days on end for a combination that keeps most of the low end torque, increases the usable power band, and is catalyst and wife friendly. Check, check, and check.
