Does anyone know specifically how they are controlling power on the procharged combinations that are on street outlaws. There have been a few hemi procharged setups and I was wondering if they can manage the power to get down the track just with timing or are they controller boost ? changing ratios ? I had heard that you would not be able to pull enough power with timing alone ?

It would appear DV hasn’t done a lot of tune up work on 60’s era Mopars. Quite a few used TDC as the spec for timing at idle...... and there are also some that use 2-5deg ATDC.

Depending on air temps, I would use anywhere from 0° to -10° to maintain rpm and build boost when staging (turbo). Procharged cars can use timing for smooth power management, and/ or blow off valve actuation for abrupt traction loss. Timing is more effective with a blower than with a turbo. Reduced timing with a turbo increases exhaust heat, speeding up the wheels in the turbo. That effect is non existent in a procharged car.

Nobody I know uses any kind of boost control with blowers of any kind. It is all done with timing and fuel.

If they get into a position where that's not enough they add a bunch of fuel.

If they are using the individual coils per cylinder, with Fuel Tech, I heard they can pull a ton of timing, even going way negative to bring the power in as they want. ...... https://www.youtube.com/watch?v=ewNUmH8Y4HY My 01 Lightning that's how I control it

my procharged hemi we use timming , i have a FAST ecu and a digital 7 ing box but its all done though the FAST , even when my air charge temps go up it takes out timming to compensate for the heat. its a big learning curve hope to get some better passes next year its been 160mph in the 1/4 on street tires and a base tune at 3960 lbs

My Moroso speed calculator tilted on that one. Lol. Over 1200 HP.

i could not get it to leave the starting line it had a 2.60 60 ft and ran 9.43 at 160 mph !!!! it did go a 5.69 in the 1/8 at road killnights in aug i was fighting a tuning prob but is was enough to win the big tire dodge class [5,000.00] my tuner wasnt at the track with me ,last time out im going to get it on a chassis dyno in the spring , yes it did make 1381 on the engine dyno on a base tune it is true hemis like to be blown LOL
