Oh oh, your story is changing (more of that wacky tobaccy perhaps?)! You originally said "To let you in on a simple mod to turn your 750f 17 pounder to a 21/23 pounder only change the older fuel pump the the latest fuel pump (simjet/ jetcat/ FTE) all can work". Now you are saying that you need not ONLY use a new pump, but also a modified ECU that allows a CP Max of 1400. That's not what you said in your 12/27 post.

I will take your bet and everyone here ion R/C U can be the judge. I have already won as the RAM 750F can indeed produce "more than 1200 /1000 (CP) with the older pump". Heck, it was a 1300 mb CP max engine stock in 1999 (with the "older pump" that it originally came with)! I know, I had one. And then I ran it for quite some time at 1400 CP max with the same "old pump" design! And I am certain that if I talk to Andy (whom I talk to by e-mail all of the time) or Carlos they will indeed confirm what I am saying.

What are you trying to claim? That all of those happy early RAM 750F owners were getting screwed out of 2 or 3 pounds of top end thrust (1000 - 1200 mb CP max instead of the 1300 mb they paid for) and no one complained? I can assure you that those engines ran very well at 1300 mb (about 17 pounds of thrust).

Please send my P-120 today. I will pay for overnight Fed-Ex. PM me for the address. Thanks.
