And if you look at the factory units and the way they configure them for testing your going to see a SPRING loaded bypass valve so 1 1/2 HP isnt going to be the load at idle with the Pettit setup maybe 1/2. As for PSI rating, you have to take flow rate into consideration, if you allow as much airflow that your intake can except your never going to see 30 psi withought overspinning the blower and or engine. Would you like to take a wild guess what your tac would read to see 30 psi and not overspin the 1.7. Not that your overspinning the 1.7, your about 700 RPM short at 9K. Why do you think im trying a bigger blower???? What if its going to make 25 psi and not overspin.

well winter is really here in Ga--so I have an ignition system to build---the ms coils actually spec out ok and they sure look stout enough--the igniter box may have been the problem--wonder if i could just hook them up without an igniter box? They have 3 pin d type connectors.
Thoughts ?
I also have a fuel starvation/cut fix to work on(stay tuned someone will have to post pics for me!) and I do have a plan!

More MAF
I made this one this morning, the screen shot number is clearer on this picture.
Almost my best ever MAF reading.

Just get the yukon coils, they're cheaper than the OEM ones and are much better. Send Juan a PM about the connectors (4-pin), or give Ray a call and he'll hook you up.

Hesus Christos! That's a lot of MAF!
Is yours just a stock setup, or what else have you done. With that much flow you must be getting into the fuel / spark / injectors issues no?

I am itching to get a dyno reading.

Just for your edification, this is what the MAF/Load values are for my turbo car at 9 PSI:
This is just a casual rip through second and third on my street. Didn't even take it to redline.
As you can see, the MAF is pegged at its maximum value (369 g/sec) so, who knows what its actual flow is.
ABSLoad hits 2 in some spots (also pegged) - all at considerably fewer RPM than the S/C.
Fortunately, the fuel calculations continue to stretch until the end of the available injector flow or this would all end very badly.
So, take your understanding of power and how it relates to MAF flow with a grain of salt.
Data is below.
