BOOSTED my ego! HeyArms' Supercharger thread
Heyarms,
Best of luck with your build... shame you didn't get a stock dyno on the same machine as well.... one question though- didn't see any mention of engine management of any kind, is that right?
If so, based on the data from Pepos (the other 7 psi boosted 250) you're going to be running dangerously lean at higher throttle levels.... that's what he needed a MAPECU3 to fix.... are you doing any datalogging during your testing, and if so are you seeing similar fuel trim results?

Never knew I'd be doing this so it is what it is, at least ill see my gains between the two stages though.You're correct, no engine management at this time. When i dynoed my car with I/E/H my a/f ratios were actually pretty lean as is, i saw numbers from 13.5-14.3 (i dont know the max value seen, it was a quick scan as they went through the log. I'm new to boost also, but they were measuring a/f from the drivers side exhaust outlet, not sure if this is more/less accurate than a wideband gauge inserted further up the exhaust piping?
) so even without forced induction, the car was lean.
I am not doing any data logging, i guess you could say I'm running on hopes and dreams, and Pepos's opinion that is isnt crazy to run 7psi as long as I'm not racing around constantly at high RPM's. I want to do MAPECU3 to calm my nerves and also be able to run safer. A few friends/mechanics want to try a different management with Pro EFI or other options, not sure if theyre even possible as no one else has done it or been successful so i should probably bite the bullet and get on some MAPECU3.
I should also add that before spring comes, i will be adding meth/water injection as well.
