"The primary bowl (on the right) actually had a top feed n/s with a .250" needle size and the secondary was a normal top feed .110". The primary n/s was run at 2 psi (low psi-hi flow) while the secondary was run at 6 psi"

Start at about 11 seconds in and set to .25 playback speed in setting at the lower right hand of video. PSI is all related to the size of the N/S. 2 PSI kept the front bowl full. . . .2 PSI (Grins)

*Note the front of the engine is too the right in video

run at .25 speed and see the difference, the STD bowl is almost 100% foam

Mr. birdcage
you are certainly cutting into my sleep time--LOL
thank you---I am paying attention

HMMM, not sure if all of the wix stuff is gonna be made in mexico or if it means any changes in quality but worth some research

[doyle hargraves]

Been running wix paper air filters on my sons crate motor and thought they were doing a decent job. Took motor in for freshen and engine builder says it has been breathing some dirt. Says it has some abnormal cylinder wall and ring wear and he needs to hone it and install what he calls high limit pistons. Not sure if the problem is wix or just paper filters in general? He suggests walker Guess I’m gonna try them.

[doyle hargraves]

Forgot to mention we always grease the filter to base area and use a sure seal on the carb to base so don’t think the problem is there

[doyle hargraves]

Just thinking about this fuel bowl thing. I wonder if anyone has ever tried a fuel bowl setup with the n/s on the bottom??

[brad hibbard]

I caution you on your engine builder's piston selection.
there are no crate sanctioning organizations that I am aware of that permit a high limit piston

the Walker filters will do a great job for you

Braswell did one as an experiment, not sure it ever went far enough to become a product or why it was abandoned

[billetbirdcage]

Generally as long as it was a good paper filter (with the wix you are good) it's the base that's tweaked and not sealing like it should.

i never could bring myself to trust a paper filter , still swear by the ole k&n that you wash and spray , i did learn that you can spray them with type f trans fluid and clean them with white wall tire cleaner and it worked just as well as the expensive k&n kit....

Not in reference to crates but latemodels in general and specifically steel blocks. Methanol vs gas vs e85 pros cons, tune sensitivity?etc....

[brad hibbard]

this should take a page or two of opinions--

the gas family of fuels has to be broken up into at least 2 categories---oxygenated and non oxygenated and in the 9 to 1 world we have to also talk about pump gas which is actually an oxygenated fuel but we do not treat it like an oxygenated fuel because it won't tune like an oxygenated fuel
for now let's leave pump gas out of the conversation

my responses will be general for now and based primarily on the 9 to 1 crate engine

for torque we will always choose methanol
the exception would be in unusually cold conditions
the down side is the maintenance involved
most chassis guys will not want you to use it because of rapid change in percentages

E85---awesome fuel
BUT --it's not a lazy mans fuel ----constant content checking and adjusting is required
E85 runs best in high heat and humidity ---
a specific "purpose built" carb is needed -----there is much more to it than jets

Non oxygenated gas
very friendly fuel for our engine and fuel system
detonation is rarely a problem
corrosion is not a problem
stores easily without special containers
lacks in power and acceleration

oxygenated gas
makes great power in cooler temperatures
easy to tune----accelerates well in most conditions
very corrosive for valve guides--piston rings--carburetors and regulators
storage can be an issue---short shelf life
stinks and costs alot of money

that should be enough to get the ball rolling

In reference to e85 you say constant checking and adjusting. I am aware that you need to check it for correct content care to elaborate on the adjusting part. Jetting or actual fuel mix
