I'm seeing at most 1.1* of knock upon tip in. Is this that bad? usually it's in between 2000 and 3500. I need to get a wideband...

when you get knock, does it spike the reading of the o2's higher or lower? I'm currently seeing 02's in between 850-900 under wot in my Corvette. The only knock activity is when I punch it and it's 1.1* or less and quickly drops down to 0* after about 4,000 rpm. Am I on the right track? I have...

You're right on. That was exactly the thread I was looking for but I couldn't find it. I forgot to mention what the turn on was. I have it setup to come on at 3-4 psi and full at about 10psi now, but the nozzle size was overkill. As soon as it started spraying the power dropped off. I...

thanks for the response. I'm back on the right track!

pulled up the seach using the terms "nozzle flow numbers" but wasn't able to find out anything. I'm not asking what the amount of flow I need for my combo is but rather what is a ballpark flow volume for the nozzle at approx 200 psi so that I can select some nozzles that are at least close...

I realize that the pressure is dependent on the pump and the size of the nozzle. What's a ballpark increase on nozzle flow from 100psi to 200 psi? I'm just trying to figure what nozzles to start with. I forgot to take this into consideration the first time and power dropped off pretty good...

I was wondering if you guys could tell me what the flow #'s of the nozzles rated at 5,10, and 15 gph at 100psi are with the pump unregulated. I have the shurflow 8000 series pump.

nope, no clue unfortunately.

I'm pretty sure it's cut with methanol.

I had trouble finding that and even if I did, there wouldn't be sufficient clearance around the screen of the nozzle, so I went with the fitting I did and just changed the fitting that mates the hose to the coupler. I'm pretty happy with it now.

I was at a hobby shop today and I saw the hobby fuel. It goes up to 35% nitro, with the other part being a split of 99% pure methyl alcohol and 10% lubricants. Wouldn't this be similar to what snow is selling for $30 for 8 oz?

BTW, I'm probably not going to be running a super high concentration of meth with that grommet. I have a 9.75 to 1, aluminum headed LT4 small block chevy with 9 lbs of boost. I'm just hoping to be able to turn off my msd btm and hopefully will be able to do that with a 50/50 mix of meth and...

the female part that i was checking out is 50785k182 the grommet is 9307k27

Do you mean the aluminum vortech overflow tank? thanks for the input

I was going to buy some of these off mcmaster.... 9307K27 Military Specification Buna-N Rubber Grommet MS 35489 No.43, AN 931 No.A8-13, 1/2" ID, 1-1/16" OD and then I saw a post that said no buna rubber. Does it just have a short life, or does it actually break down in the methanol? I...

found everything I need at mcmaster. It just took a little more looking. I got some ideas from the blowerworks catalog. I went with a female to female adapter with 1/8 npt on one side and 3/8 on the other. On the side with the 3/8" I'm going to toss a male 90* on there. There screen for the...

I'll probably go with the female 1/8" to female 1/8" then get a 1/8" male to 1/8" male fitting to go in the opposite side of the nozzle. Thanks for the idea!

so you don't sell that part serarately? anyone else have any info? The reason I use mcmaster carr is because I usually get my order the same day since their warehouse is 10 miles from my house. I'm open to buying them from whomever at this point though.

I bought some nozzles at mcmaster carr and need a 1/8" male to 1/8" female npt connector to get them to mate up correctly. Also, I need to get something that will give enough room for the alky to get into the screen section of the nozzle. I checked mcmaster, but must not have seen it. Any...
