I will play wth it today and see if its not too hot. I have been reluctant to peg the throttle because its very warm her in So-Cal. Typical August..100

Oh, you Californians, always unhappy about the weather. You're as bad as the bloody Brits It's nice and cool in Blighty today - unfortunately the roads are somewhat moist, and the air has lots of stuff that won't burn in it.

If I got it on the floor as soon as I shifted into 2nd, it'd make boost pretty soon. Although the stock 930 once got the car quite out of shape when I just floored it in 2nd so I tend to be careful about doing that - and especially so, considering that 2nd is the weakest gear in the 915.

If you convert to a C2-style diverter setup, don't even think about the plastic Bosch valve. I held the one that came with my Kokeln in my hand for about 3 minutes. Then I went straight into the house and bought a Forge billet replacement on Ebay... Twice the size, strippable, rebuildable. New, it's twice the price of the nasty disposable valve. No-brainer.
'77 S with '78 930 power and a few other things.
