Great stuff Carl You're going to find that your new injector is going to make this thing a whole lot faster! Faster equals more fun! LOL When you get to tuning it - if you need any help, let me know. Did you do a leakdown on the spool valve - to set the leakdown - or just manually getting it going. How many lb spring do you have in your idle poppet?
Na Dale i didn't do a leak down, 5-6 spring on Idle poppet, .120 main jet, .011 nozzles and she shure sounds great need to get some seat time and TnT
Tell you what Carl - I will get out my fuel injector formulas and do some calculations on nozzles, main jet, etc.. One thing that is a problem is that we have no idea as to what your pump flows. Which version is it - is marked on body as to the size. That may give me enough for a ball-park estimate as to where to start. Also, I can't remember if that is a Hilborn or an Enderle pump??? Having a 'leakdown' gauge setup to set the spool valve is a good idea - otherwise you're really guessing as to how much is going through at idle. It seems to me that four .011 nozzles will be way too small. On the FlatCad on gas, we ran eight .026 nozzles and about a .108 pill at 15 lbs of boost (372 cubic inches - 570 HP).
Well somedays ya cant find the fitting you are looking for so..... what to do? well get some brass stock..... remove everything that doesn't like what ya need, And presto grigeo...... a fitting emerges..... beats the hell out of the mickey mouse adapter I had on it...............
Got the info back on the pump flow Dale 2000 rpm 7psi 1.02 gpm 4000 rpm 29psi 2.68 gpm 6000 rpm 62psi 4.09 gpm 8000 rpm 100psi 5.18 gpm
Hey Carl - over the Holidays I've been working on a software application to help with MFI tuning - and associated conversions back/forth to EFI (which is for my own usage). Now there are a lot of simple applications out on the WEB, but they don't have all the stuff I want/need. So - I decided to take all the math and write my own application. It is in the early stages, but I think it can help you even as is . . . as it has calculations for things like air density changes -- to automagically calculate the approximate main pill changes to account for how the air changes. Anyway - will package up a version over the weekend and get it to you. This is written for a Microsoft Windows application world - hopefully you have a PC that is running Windows 7 or better? Let me know . . . B&S
Yea Cowboy too bad my camera battery went dead or the video would have been longer, she really lites my fire now....got a grin from ear to ear........more video later.....
