I wouldn’t worry about percent of overdrive. What Boost was he expecting. To put you in the safe ball park you should be flowing .37 gpm per pound...
Will send tomorrow
I would talk to Spud on the pump sizer. You can put one in and turn the check valve in reverse so it is shut off for now. I use the pump sizer to...
Yes it is. When originally published years ago it was based on the flow of water. I corrected it to be the flow of methanol. Email me at...
Think you should I think you should start off around 20-22% OD with this blower
Yes, you are going to need some fuel. How much boost at what rpm do you want to start off with? What is the cubic inches of your motor.
I think if you are going to have to get rid of fuel to go leaner then you are going to need a pump sizer with a 28 lb check valve
Is the Hammer blower a high helix? I would get the name of the person selling it and call Troy at Hammer and ask him about it. Phone 469.877.1957
You don’t have the tuneup for a better blower. If you put the LB22 you might go too lean. I would call Spud and get what you got going.
I wouldn’t change anything until you have talked to Spud. The high speed is set to come on at 105-115 psi so that is not a pump loop.
The ideal fuel pressure I have found to be 125-130 lbs at 8000 in first gear. If it is not there then I change all the nozzles by a percentage...
Motor week, do you think that maybe what you think is the pump sizer is the fuel shutoff return. If that is the case you don’t have a pump sizer loop.
Nozzle area is a factor of pressure. The higher the pressure the smaller the nozzle area. It is hard to compare one nozzle setup with another...
It appears that you are ignoring the fact that racers are advising you that you are way rich and you haven’t answered the question on the pump...
Spud at FIE makes one with a switch in the cockpit
Yes, I guess you could using a crossover switch.
Bob, sent them again to you. Let me know if you got them
There is no check valve or jet in your pump loop/sizer circuit. There should be a jet in the brass fitting that screws into the top of the pump...
Your plugs should color in one run. If not then you are probably way rich so much so that small changes to the fuel are not making any difference....
Email me at mike.c@mindspring.com and I will send them to you
