i just spent yesterday doing the following things to my z28

-installed a full pan splash shield under my rpm intake.

-totally blocked off the heat cross over

- rerouted fuel line from pump to carb away from the block, resealed fuel pump to block, moved the fuel line on the frame farther away from the header.

-covered fuel lines with foam to try and keep heat of them in the engine compartment.


going to the track next sunday wondering if this is going to make the car mph more or not. i think its not going to make a difference but i thought i was worth a shot.....


i went yesterday to a garage sale and bought a nice wall mount thermometer,barometer,humidity meter gauges.

i was going to take this with me to the track to record readings from it. shoulld this be placed in the shade for reading or where is the best place.....

right now the gauges read in my house 71 degrees,27.35 barometer, and 44 percent humidity......what does this tell you .....as far as how it comes out for above sea level.....how do you figure for elevation......

I always place my thermometer in the grass, in the shade under my trailer to try and keep the same conditions. I don't know the best way but I try to keep it the same way every time.

i just got done doing some reading on the car with a digital temp gun....it appears that my fuel bowls are running about 25 degrees cooler and the intake near the heat cross over is about 40 degrees cooler......the carb bowls was about 130 to 140 degrees to hot to kee your hand on them but now there about 105 to 115 degrees cool enough to keep your hand on them now......the intake near the heat cross over use to be around the 220 degree mark but now reading are around the 175 to 185 mark......of course this is a fully warmed up motor......

so it looks like the little things i did are helping some...not sure its going to make the car faster but might make it more consistent....before the car would fall of quit abit if it was warm.......i was getting my best e.t.'s with the car at 150 degrees before i hit the water box.....by the time i got done the car was about 165 degrees.......

looks like i might too lay mine under a trailer or something for readings now i just need to learn how to convert the information to sea levels and what not.......

Do a search for auto math and weather conversions. I have found some good stuff but don't know the sites.

This one was in my favorites.

good site thanks.......if i figured right then the info i put in the caculator says in my house it represents 3950ft above sea level right? the actual ft im above sea level here in kansas is about 1600 ft i believe

You realise that the barometric pressure changes constantly, and that your calculated altitude above sea level can vary by hundreds of feet from day to day.
