Have you ran this combination, boost, fuel and timing, before? The reason I'm asking is the last blower motor(496 C.I Hemi with aluminum Stage V heads, 10:71 blower with two 1050 Dominator blower carbs) I dyno tested didn't like 25 degrees with 12% overdrive that made 12 lbs at 6500 RPM using Union 118 octane race gas. The same motor liked 33 degrees BTDC with 10% underdriven making 7 lbs boost at 7300 RPM on CA pump gas Don't be afraid to sneeck up on the timing, we went to much to start with with the O.D. set up and tried more, 28 degrees, and ran out of dyno time before we could try 23 or less Please let us know what the motor makes and the details, Good Luck Mr.Cab Racing and winning with Mopars since 1964.

Cab there are a lot of thing effecting what fuel to use.i was running 110 sunoco before without the intercooler at 270* IAT,30* timing.NGK #8 plug,14lbs of boost at 10% OD. With the intercooler and tap water my IAT was 130* and with the bigger carbs the engine will be happier at that same OD.i went .200 faster with 20% less drive with the bigger carbs so at 10%OD it will make more HP.

The last motor liked 130 IAT a lot better with 7 lbs of boost underdriven than it liked 180 to 190 F IAT at 12 lbs of boost with 25 degrees BTDC overdriven with the better gas There was around 100 HP differences, 927 HP at 7300 RPM with 7 lbs boost and 33 BTDC timing and 130 F IAT, twenty minutes later the motor made 1024 HP at 6500 RPM with 25 degrees BTDC with 180 IAT at 12 lbs of boost, it started to go into detonation so we pulled the throttle back Mr.Cab Racing and winning with Mopars since 1964.

Or the delta temp between staged and traps? Just curious. I have little to no experence with roots blower setups and would love the info just to compare. Thanks. Aaron M
