The 5 second dyno run does not bode well for the performance above 150mph, the next ~15+seconds this thing runs at full load to reach ~190mph are an unknown I guess ?

In Europe the biggest weak point in these cars is the gearbox which is proving very fragile with torque much over 800NM due to the shear spread of the torque - flat out at 3000rpm in 6th to 7000rpm is killing the boxes....
I really doubt this car needs 15s from 150 mph to 190 mph. one way to find out is to take it to the TX mile. next one is in october and with this power my guess it should hit 200mph in under 25s.

I was meaning a total of about 20s to do 0-190. This sort of power will deliver this sort of performance - Getting a 5s dyno run to translate into this sort of power for a 20s fully loaded run is a challenge and stopping the gearbox from shredding an even bigger one

yes, i have asked tym to take my car to the texas mile on my behalf. i will be in Spain so unfortunately i will not personally be able to attend. the redline is currently set at 7800 rpms. i shift out between 7000 - 7200 rpms for regular gear changes. 7800 rpms was so that i could finish a race up to 150 mph in
4th gear without having to shift into 5th.

Geez and I thought my 7300 redline was high (I get to 140mph in 4th). If I can make it this year to TX I will definitely check your car out. Never thought stock internals could tolerate so much stress....
