Graph looks way smooth, don't think he is having any issues. But I do hear what you are wondering about in the video. I noticed it on the first dyno but not the 2nd one so much maybe it's a roller making the noise on the first one?

I think there is music overlayed throughout the whole video. It does sound like some kind of oscillation at high rpm though.

Damn 38 psi on a 6870 for only 900 whp. I think the N54 head is just not meant for big power
The head while bad stock is ok when ported. They just need work. Leaving the head unported going for this kind of power honestly makes little sense. The head is off to build the motor, and instead of addressing it you just put it back on stock? It flows so poorly stock, you are working everything else so hard to make the same power. There is a reason Tony made similar power with almost 10 psi less. Flow

So after a couple more pulls we tore down the transmission to check to see if it was happy or not. The guy who "upgraded" the transmission just did a rebuild turns out and the clutch packs where starting to go bad. So while its apart it will get nizpro shafts and propulsive clutches. I'll let you know how it goes. This car also has the xhp stage 3 flash

propulsive clutches wont fit in the nizpro baskets already inquired. Last time i checked Nizpro only had a couple hardened shaft and basket sets left for 5 grand. Nizpro has their own upgraded clutches for it.
