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...

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.

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?

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...

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...

I have a controller that I'm trying to bypass 12v to "prime" the alky system prior to it going into use. I got the controller off a wrecked car, so needless to say, it doesn't have all the features that I'd ideally desire. My question is, I've heard that if you bypass the controller to...

I know that most of the systems out there read off the maf sensor. What should I do since my car is speed density? Or do I just go off the map sensor? This is for a 92 LT1 vette. Thanks!

I have plenty of flow at the psi it came from the factory set at(100psi). Is there any advantage to bypassing it other than higher flow? Will it make the response of the system smoother, ie less tiny fluctuations from the pump cycling on and off at 100psi?

I have the 8000-543-238 pump (2-3851) which is rated at 100psi. On the pump there is one wire into the controller and then one red wire going from the controller into the pump. I spoke to a tech at shurflo who said that you can bypass the 100psi controller by connecting the red wire to you 12...

What sealer is alcohol resistant? I would like to touch up my bulkhead so that it doesn't leak at all.

Just curious...

You read that right, $100 shipped. These sell for $139 all day long. If you're going to a dual setup, this is the perfect buy. It comes with the 30 micron filter sock, high pressure tube, harness, clamps, rubber isolator sleeve, and instructions. It is brand new in the retail box. This is the...

Or post a link to where I can read about the sizes. I saw a post where I saw M10 and M15. Is that in reference to the flow in gallons? I've never had to size nozzles, so help me out here.

Which is the most tunable? I already have the rest of the kit, just looking to upgrade from a hobbs switch to a fully tunable controller. What do you suggest and how much is it? I have four cars to buy these for, two of them are mine and two for my buddies. Also, what features do you...

What mix of h20 to meth, boost level and horsepower level are you at and what is the flow of your nozzles?
