Hey Folks,

We've been testing the MAFterburner STAGE2 as used in the capacity of a dry nitrous controller. Here are the latest results of spraying a 50hp and 75hp dry shot using only the MAFterburner STAGE2 (provided air/fuel tuning, RPM switch, and WOT switch) and 50lb/hr injectors to perform the fuel enrichment.

Please keep in mind that our goal for today's tests weren't max power, they were to evaluate the fuel system and the capability of performing fuel enrichment with bigger injectors and our STAGE2 MAFterburner.

Here are the graphs. 50hp jetting first...

...75hp jetting

and the 75hp jetting:

I'm not making excuses for the low numbers :eek: BUT is important to note here that:

1. bottle was running low on nitrous
2. pressure was low (couldn't run the warmer because battery was dying
3. wheels slipped on rollers which caused a break in the chart.
4. the supercharger belt is slipping BIG TIME (Dougy, I need a 3rd idler!).

Best,

MJ

Hey Jim,

Stock pump running at stock pressure results in plenty of fuel with the 50lb/hr injectors.

Impressive numbers! Which brand 50lb injectors are you using? Are you also using a Diablo Chip?
Bosch 50's, flow-matched by Precision Turbo & Engine

Same Diablo chip that I got when I first started modding. It was a file done by a friend out in SoCal which gave me more low/mid timing. Air/fuel controlled by eFPC and MAFterburner.

Can you send me some pictures of the Bosch 50's? I have never seen those before.

I thought Precision only sold Delphi 50's.
My bad, my recollection was incorrect. I just went through the old emails I had from the Ebay seller I bought them from and they *are* Delphi brand injectors. Ooops.
