I have compared fuel to air in testing and setting poppets and it does not make enough difference to worry about so I don't make it complicated....
I mean the port poppet not the nozzle....sorry.
Lucky, is your port nozzle set at? Have you checked it lately? Rootes blower should run pretty cool at idle. If you feel under the rear of the...
The port poppet keeps the port nozzles shutoff during idle so that all the fuel goes to hat to lubricate and cool the blower. If not you would...
Eli, SoDak asked what would happen if the clearences were too tight. The only time a blower should be considered too tight is on the initial...
If it is too tight it requires more HP to turn the blower and generates more heat.
I think the better quote would be "If it worked then everyone would doing it already"
Again, the power at rpm is really only available at a specific air to fuel ratio. As I previosly stated the Rootes blower has real bad efficeincy...
Dave, sorry I confused you. Yes, leak testing a BV is so you know how much fuel is going through the BV at idle. The percentage amount is a...
You can leave them hooked up and use the percent solely as your own reference but if you try and compare it to someone elses percentage then you...
You leave those lines open
If you are leaking the barrel valve the hoses to the hat and ports should be disconnected from the barrel valve and the idle return should be...
If you drill the poppet then surely you would change the pop point. Are you doing this so some small amount of fuel enters the port nozzles when...
That four hole JBR is a great hat. One of the things that can be done to improve it is to add a custom CNC spacer from Darren Mayer see...
What hat do you have now? What carbon fiber hat are you talking about?
Post Tim Rudy's phone number and email address and we can sure let him know (lol)
If I understand you correctly you are asking about a Rootes blower and not a screw blower because they are totally opposite on fuel requirements....
The fuel requirements of a Rootes blower are totally different from a PSI or Whipple screw blower because of the inefficiency of a Roots blower...
Which -10's....the R5671A-10 or the R6061-10A
We use a front crank support and we find that it stops our crank from flexing and gives more life to the main bearings especially number one and two.
