IIRC; HD M2 roll bar is 1.5" diam x .120" wall (or 38mm x 3mm wall for us)
Also this is going in when I figure out how to configure 36-1 trigger setup in Adaptronic

What is this creamy thing doing in my valve cover and cylinder head :(
Time to do a compression&leakdown test:
cyl#1 = 203psi. leak-down = 4%
cyl#2 = 193psi. leak-down = 16%
cyl#3 = 196psi. leak-down = 10%
cyl#4 = 209psi. leak-down = 5%
Nice. Head is warped ..again.. (I did loose a water hose last summer and it overheated)

...and there we are now...

Thanks man.
With the large exhaust, boost creep seems to be a constant headache. It’s same with the 2871's internal WG, even if I zip tie the wastegate lid open boost still creeps to 15psi towards the redline. It makes the road tuning little bit difficult as I have to concentrate so much to traction.

Looks promising

Keep in mind that last year when I did that 287whp virtual dyno run, I went to the DynoDynamics after that. Real DynoDynamics dynamometer gave me 284whp so there's a very small error margin. Both runs had been taken in the same road, same gear, same tires, and same VirtualDyno profile
Although VirtualDyno isn’t a real dyno it is still a good result, 330whp with only 15psi. Seems that the Honda IM is flowing well
