I would have run up to 45psi on the dyno (map sensor limit) but the wastegate spring will only allow 40.5psi (280kpa). If the engine is still going when the season finishes I'll probably change w/g springs and see what it makes on 45psi, time permitting. I'm not holding out too much hope though, the engines done almost 2 seasons racing plus 2 powercruise events, dirt drags, and whatever else. I'm glad I didn't switch to E85 yet, pump petrol is starting to get real interesting now!

That is just impressive as all get out. What ECU are you running and what size BW?

But but but.... bdc?

Oh really? I FINALLY have in my possession the Bosch Motorsports Coils (I've actually been using them for a number of years now) along with the IGN-1A coils (running my RX8) and a set of factory D585 LS2 coils (thanks Glenn) Whenever the FC does make it onto the dyno after I get her tuned to about 12-14ish PSI I'm going to swap coils, adjust dwell and make a pull. Whichever coil makes the most power, is the setup that will stay on the car. I think it'll be between the IGN and the D585, and I have a feeling it will be the D585, although the IGN was designed around a 2-stroke Merc outboard soooooo, it should be interesting
