MSD 20 to MSD 44

We run a Chevy 540 with a 1471HH. Right now we are running in the 3.90s with a MSD 20 and was thinking about running a MSD 44. Would we see a big increase in the amout of fuel that could be burnt and HP gained or would it stay about the same.
Thanks for any info.

I believe the HP would be about the same, the ignition will just be more reliable, and it will run cleaner. How much timing are you running now, you might want to back that off a bit. Someone else on here might have more experience as to whether the tuneup will change or not.

 

Ken we are running 30 Deg in the car.

 

I guess it depends on how much compression you are running, and boost. Typically, with a 44 amp mag, I would run a maximum of 28 degrees with a roots blower, but your compression shouldnt be more than about 11.2 to 1. If you are getting good boost (40+) and have higher compression, I wouldnt run more than 24 degrees.

 

Msd 44

Ken we are running a roots, the compession is 11.5 to 1. We are making 48# in the 1/8 and 52# was the most.

Thanks TJ

 

TJ what kind of roots are you running and how much overdrive?

No shit add like to know how much overdrive and name brand of blower also

 

K11 Superman at 44 over... made 52 out the back ...48 to the 1/8...now 50 over because she's a little bit worn makin the same..i own and drive the Altered

 

We spin the blower faster to make the blower think it's got a hemi or promod motor underneath it

 

I'd venture to say that blower wouldn't make that much boost on a hemi head. More flow = less boost.

 

We shift the 1-2 at 8400, that's when the clutch gets tothe motor any later and it starts going into shake and shift the 2-3 at 8800
