High HP guys--- Strange noise under WOT
I get a strange noise under WOT. It sounds similar to a midget beating on the firewall with a ball-peen hammer. When I have good traction it does it. When the tires are spinning, nothing. It won't do it in 5th or 6th, even when spraying N20. But in 3rd and 4th, when the tq load is high, I get the noise. I can't seem to find any thing that's hitting in the driveline area. I was just wondering if anyone else with big power has had a similar problem, and figured it out.

symptom: It sounds similar to a midget beating on the firewall with a ball-peen hammer
fix: took hammer away from midget under dash.
sorry man i just couldn't pass it up.
i would suggest you take a good look at your exhaust. mine can make one heck of a noise at 48 pounds of boost sometimes. and i am still not sure where it is coming from.

Very Funny....
Flywheel bolts are tight, but it is a strange coincidence that this sound only appeared after I installed the Twin Disc clutch...

I went from a ConFE to a DD. The FE wasn't slipping, I just wanted to start sledpulling. I did add some power,(went to the Twins program and CLDL) at the same time, so I think it may be due to the extra torque.
What I'm really thinking it is.... The double-cardan is binding up and the ears on the yokes are hitting each other under good traction, quick acceleration pulls. The lift-kit magnifies it by increasing the angle the front driveshaft makes... I'm almost positive that's what it is.

Might be a little off topic....
I had a sports car that I really enjoyed. If I drove normally, no problem. But if I started to take turns a little faster, I would hear some noise. If I got a little throttle happy and started breaking all of the speed limits, then the noise would get really loud. And really annoying.
I finally figured out how to correct it. I stopped taking the girlfriend in the car with me.
