310kpa or 44.9psi!! (only in the top of 3rd and 4th gears tho, I'll fill in the boost everywhere else next season, plus more total if needed) 162.5mph to date.
The engine still seems happy too - 2 drag seasons, 2 powercruises, 1 dirt drags, and some street use later. Hopefully it does a 3rd drag season.
Surprisingly enough the engine appears to be several times more reliable than the methanol 13B's we race against. Trap speed is equal to the methanol 28x9 tyred cars too (this with our smaller tyre and heavier car), and there is still more power in the engine yet I'm sure.
In retrospect it's quite amazing how much reliable power such a low spec basic engine build running on petrol can produce. Only with WI of course, it wouldn't even get close otherwise. Frank Walker of Pratt and Whitney resoundingly proved this all those years ago.
Still running inductive ignition too. It's cheap and reliable.
