Over 1000bhp under 1000kg
Went to my local 'conservative' dyno on Friday and made 1010.5 bhp and 860 lbft torque. Boost was 1.6 bar midrange and rising to 2.0 bar from 6000 rpm (to limit midrange torque)
The turbos just wanted to take off, even at this level it was gaining over 30bhp per 0.1 bar boost with +3% wastegate duty. My poor open deck pegged block must be creaking a bit at 2 bar so I stopped there.....for now! (closed deck block is nearly ready to build)
On the street tune I had done at 1.2-1.3 bar it dyno'd at 777bhp and 665lbft, that was pretty much on the button as I only managed to get a measly 3bhp more with further tuning at that boost.
The max I plan to use on the track with this block will be 1.5 rising to 1.8 bar where it made 945.5 bhp and 825 lbft torque.
Fuel was scottimax version 2
No methanol is used in this version.
I had planned to test the 150bhp N2O kit but with circa 150-200bhp still to come from the turbos and already seeing 1.2 bar at 3700rpm (which spins the wheels up 1,2 and 3rd) there really was no point!
At this level in a sub 1000kg car, for the first time in my life I can honestly say I don't need anymore bhp !!

It's amazing to think how far you've taken things since the days of M104 FUG. I recall chatting with you at Well Lane years ago where you made 417bhp iirc, which at the time was an awesome result. Now with power nearly at three times as much it shows just how far things have progressed.
ill pay as a passenger tooo
