Street Outlaws Procharged Hemis

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 ?

"An engine with ignition set at TDC does not produce enough power to idle": David Vizard

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.

Complete and utter fallacy.

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

Dave is a pretty smart guy but he was probably just thinking about Chevrolets.

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. ......

Look for solenoids on BOVs... especially on cars with dual BOVs. We all know how simple a BOV can be used/ plumbed. When you can’t see where the actuator lines go......

Timing is more accurate and much quicker acting. If they get into a position where that's not enough they add a bunch of fuel.

Or todays G3 hemi

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

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

And I no you said with street tires, but at a 160mph there were a lot of tire spend. What et did it run?

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
