    I vapor lock in city driving when I'm using the saddle tanks, but only on those 95+ days. I switch to the fuel cell and problem solved. Only problem, 5 gal cell @ 5mpg. Hope there are no long delays.

    I should finish these last changes in time to do some road time next week. (or the week after next)
    Track time should happen Sunday in BG.
    Drag Week 2012 (wet paint and no transmission but finished) Drag Week 2013 Daily Driver finished in middle of pack (again) Drag Week 2014 #56 of 126 Daily Drivers. (getting closer to the 32)

      I just changed mufflers and taking the potatoes(flowmasters) out of the tailpipes really threw my air fuel ratio for a loop. Its one whole point more rich at cruise and 1.5 at the limited WOT I was able to due. Now I know why this thing didn't respond to jet or carb changes....it was constipated!
      I was thinking about real sound control devices this year but had no time or money to get it done. I did bite the bullet and got a AFR gauge kit and will install this weekend. Hope to get a little better mileage.

        Mike have you looked into fuel pump drivers that duty cycle the fuel pump? as seen on the latest Roadkill, so it has to work!? also I'm bringing same old Blue LX, 4 quarter mile passes, all sucked. been index racing 1/8 mile and some cruzing. Good to go.

          Went to my local 1/8 track last night with the 94 camaro and went 7.04 at 100 mph and got booted cause forgot my helmet. It isn't caged so will be limited to a 11.50 I believe. It's a 6 speed car so hope it stays together. Oh and I didn't get a spot for DW so I'm just gonna show up and hope I get in.

The vapor locking I still need to work on, the fuel gets hot and boils in the tank and then the fuel pressure starts droping. I plan on wrapping the exhaust where it goes by the tank. Any other sugestions??????
            How far away is the tank from the exhaust.. rapping heat blanket around the exhaust
            will help .. but if its close then in traffic you might still see a problem(the rap slows the
            heat transfer.. it doenst eliminate it).. maybe a fan or a deflector to push some air up
            onthe tank/exhaust area will help... I prefer the deflector style since it doesnt draw power
            but you have to be in motion
            EDIT
            If you can get air flow up on the tank it should cool it ... rapping the exhaust will
            help also... when you are idling in traffic you dont get much heat from the exhaust
            so if the under hood temps dont go crazy it should be ok... if the under hood temp
            stays high then a cooler would help

              Maybe run the return line through a trans cooler or something similar.

                I think it was GTA91 that is doing that and having good luck.

                    Going hoodless works for me Mike. I'm not ready myself, but working on it. No track time, and no road miles on this engine. Testing in front of my shop has shown it going lean at WOT. Changing carbs now. I was going to run it in Odessa fri night but not sure it will make it. I need to put a smaller pulley on the water pump because it's turning it too fast to let water cool in the radiator. But it RUNS, so I'll be in BG sunday morning. I need to change my seat belts out too. They expired in june. I already have the new ones.
                    Go ahead, pull my finger.

                        Are you sure it is vapor lock in the tank? I have been driving hot hot rods my whole life and have not heard of that. Most likely fuel pump. Is your tank vent working? If you have electric fuel pump, is it getting hot? Is your power wire to pump big enough? Hook a volt meter strait to pump and watch voltage when hot, check ground too. Even try piggyback extra wires just for a test. Try a return line to keep the fuel moving. I switched to mechanical pump because too many electric pump failures. Lutz runs a mechanical pump too!

                          A smaller water pump pulley should make it run faster, you might go smaller on the crank pulley to slow down the waterpump

                            Mikes deal is injected. And I'm pretty sure he runs a return style aeromotive setup. If he says the fuel is heating up he's pretty sure of it. All my fuel hoses from the trans forward are run in sleeving with reflective coating. I run a product engineering electric with a -8 bypass and a dead head regulator with a .022 bleed to keep it consistent. Is it all sleeved with heat sleeve?
