  • Nitrous plate with spacer?

    When I mounted my plate kit I had a 1 inch spacer under the the carb.I pulled the 1 inch plate when the Nitrous kit was installed.I noticed right away mid to top end performance was lacking N/A.I am thinking to add the 1 inch plate above the Nitrous plate.Any clue if performance will be had adding the spacer back above the Nitrous plate?

    Was it open, or a 4 hole spacer?

        I would put it back on "below" the nitrous plate. This way the nitrous mixture will mix sooner with the carburetors atomized fuel.

          I was thinking the same but Stevie owner of Induction Solutions says he preffs the spacer above the Nitrous plate.IDK going to try both under and above and see if any gains will be had..
          I will say this if youre running a RPM air gap or non airgap RPM intake.The one inch open spacer will wake up the RPM intake N/A.

            I mounted the spacer above the Nitrous plate..This time of year I run 7.5's in the 8th mile..No changes in jetting or timing with the spacer ran in this order..7.46 7.45 7.44 seemed with the cooler air coming in the better my et was had.Yet it was very humid weather.Never dead hooked either through out all the runs..Lost 60ft times not hooking but picked up 1 mphr..I have a few things in mind to adjust before my next outting..
            Sidenote my conrads at the track said THATS A BRACKET CAR that will win many rounds..Very consistent but my rt's were all over the place.

              Are you using any kind of traction bars? Or maybe a torque arm?

              I picked up a factory torque arm mount for my Vega a couple of years ago. But it seams to run straighter with just the traction bars.

                4 link with boxed lower arms with solid bushings. Top arms are adjustable..Kit was purchased from Southside performance..Its time for new rear meats these are done...
                I found my old 4 hole spacer that I used..Its a 1/2 inch the 1 inch open spacer clearence to hood was to tight for my likings..
                Thanks for your speedy reply BITE ME...

                  Update last outting 7.36 no change in the tune.Timing on this tune is very conservative..Going to add some timing and get after it..Hold on to your hats for my results..

                    I came to the conclusion old faithful isnt going to get me to where I want to be 8th mile.Nothing is wrong with the engine just time to step up in performance..
                    421 SBC AFR 210cc's headed12:1 Lunati custom roller cam is being built as of last week.Steel crank forged rods and pistons.Engine builder is well known in my area.
                    Builder said this combo will ET on the motor better than what my current combo is doing on the nitrous.
                    Once dialed in will introduce some nitrous to the combo.
                    Stay tuned for vids of the new bullet.

                          Sounds good.
                          I need to get a pair of plates for my dual quad Ford 460, before I do a piston, and camshaft swap. Then I'll only have 1 vehicle that doesn't have nitrous....till I get a LS core
