Spud Miller's Cave / Idle Fuel Pressure
« on: April 15, 2019, 06:08:49 AM »
Hi Spud, I know there are many variable but what approximate fuel pressure should we expect to see at idle.
392 Hemi, 6.5 GPM Hilborn pump, .034 nozzles, .125 Main with 22% leak down
Calculator shows around 110 psi at 8000 rpm.

 8) We also have a nostalgia meet at the end of April hoping to complete licencing passes beforehand so we can race.
Will be my first passes in many years, can't wait. ;D

I think most everyone has a legitimate point in this thread but, sorry Noslin,  I lean toward the bottles should not be that exposed. Even when legally mounted look what happened just this past weekend at the Gators.

I would say the program is compensating for an out of whack inlet to exhaust ratio. By increasing the inlet a more favourable ratio is achieved and therefore you see increased HP.

 :( So no one is using a cheaper option to a GoPro.
 ;D All good, glad to see everyone is focused on the important Go Fast stuff.

Thanks Jon clear as, 35-40 will be our starting point - no wing.

Jon's Wheel House / Front Tyre Pressures
« on: February 05, 2019, 06:41:30 AM »
Looking for some advise on front tyre pressure, 220" FED, approx. 1750 lbs wheels are alloy not spoked.

Even at 1800# a fairly mild methanol stack injected 392 with cast heads should make enough power to run 8.60
Currently helping out building a 392 now to go into a FED should be on track in a few months

Spud Miller's Cave / Re: 16 nozzles pressure
« on: January 26, 2019, 05:49:52 PM »
It would be unlikely that you could match your 8 nozzle area exactly when using 16 nozzle out of the box. eg 8 x .032 = .006434, .006434/16 = .000402.
.022 = .0003801, .023 = .0004155. Using .022 will see a bigger increase in nozzle pressure and decrease in main pill.
I would think more nozzles with the increased pressure would result in better atomization but the placement of the nozzles would be more important to see any improvement.

On the subject of water, what is your preference when running alcohol, pressurize the system or just fill.
Obviously pressurizing lowers the boiling point.

Electronics / Camera

Just wondering what brand, resolution, lens angle camera you are using onboard. Will be back in the seat after a long layoff and thought I might get a camera, initially to critique my driving.
