promag 20 vs. promag 44

We run a 526 TFX, AJ fuel heads with an SCS 1471 (38# boost@7800rpm) in a 3000# T/S car. The fuel system consists of a 4 hole JBR carbon fiber hat and an enderle 110 pump. We're currently running a promag 20 and are wondering if it would be worth the money to step up to a promag 44. At first we were concerned the fuel pump wouldn't meet the demands of a 44 amp mag but saw one of our competitors running consistent 6.40's with an enderle 110 and a 44 amper. We also have a fresh promag 12 and Dunn dual drive and wondering if it would make sense running the 20 and the 12 in a dual plug setup. Also note that we have a 4.10 rear gear that puts the car through the traps at about 7800 rpm. @ 6.90's /187 mph. We plan to switch to a 4.56 gear soon. Any advice would be greatly appreciated.

 

I find that hard to beleive that you are running a 110 fuel pump, it is most likely an 1100 or even a 1200. Remember 110, 990, 1100, 1200 fuel pump castings are all the same, actually 110 is casted in, look at the numbers that are stamped into the fuel pump.

 

Almost all blwn alky cars run a single plus setup with a 44.

 

It's a 110.

 

Do you have the flow sheet on that 110 pump?

 

Kinsler flowed it but I don't have the chart in front of me right now. I also noticed a 110 (yes I looked at the casting numbers) on Joe Boniferro's car which runs consistant 6.40's. Also note that since we don't have a data logger we're afraid to lean it too far and every pass we've made has been with a pretty fat tune.
