Projects rebuilding after the crash

Discussion in 'The Hokey Ass Message Board' started by racer-x, Sep 19, 2015.

  1. What do you mean by "went out"? I assume it means "lost fire" but why? What is the fix? Is it simply a need for new plugs or do you now have an internal issue like a piston with a hole in it, a valve with a chunk missing or a head gasket issue?

  2. I dropped the compression by a point. That makes the tune up rich. It just needs to be leaned out some more. There is so much volume with a nitro engine even with a 44 amp mag plugs can get wet. Trust me if you had a hole in a piston or a bad valve you would know it. Each cylinder has a pair of nozzles in it. They are easily exchanged for smaller ones. Dropping cylinders and running 45 degrees of advance or more is very hard on bearings. Yesterday i pulled the pan for a look. The rods were nice and shiny on the upper shells. They were replaced along with the mains. The car was converted for street duty. Its ready to hit some local shows. Georgee Porgies saturday Holtz Motors monday. Stop out.
  3. Cylinders are out. The raw fuel can be seen flying out. Screenshot_20220630-064921_Facebook.jpg Screenshot_20220627-211447_Facebook.jpg

    & another old trick when a cylinder goes wet / out you can lean pump by hand & 50/50 it will reunite those cylinder/ plugs , then pre stages & go full pump volume, Most of us know there a fine line running Nitro

  6. It was at the hit not on the burnout. Very bad things would happen at wot trying that. I do know what you mean and i have done it.

    Brian you are like the big show cars, if it drops one or two you are on for the ride then you reload for the next pass.
    You are living the dream.
    Keep it up.

  8. After the chassis dyno session last spring the car has run hot. Some areas of the fuel map were decreased by 25 plus percent. Now that its tuned and burning the fuel it gets hot To help with the heat during street driving im adding a extra set of fans that will be pushers for a total of 12000 cfm. Im maxed out on water flow. I have a 55 gal maziere pump. The water lines were increased from an -12 to an-16. So im going after air flow. The radiator is large and thick. Im thinking it needs help putting air through it. I have the extra fans mounted. I also reversed the air flow. It now pulls air through the trunks louvers. Pushing it out the louvers may have been a restriction. There may have been a high pressure area over the trunk while driving. You couldn't touch the trunk lid it was so hot. I will wire it up in the morning and try it out in the evening.
    If it was easy everyone would be doing it. There is no you tube video out there on how to tame this beast.

    Imagine filling a 55 gallons drum in one minute. Now try it through a -16 hose. I think the hose should be bigger.

    -24 perhaps? That's 1-1/2", like a lot of radiator hoses

  12. The hose is as large as the largest fitting i can put in the water pump. They dont make a pump with AN-20 fittings.
    There are two lines out of the pump going to the engine. Then two lines out going to the radiator

    Oh, I didn't know you had two lines going each direction. That should help a lot.

  17. The car was converted to a race car this morning. All it needs is a little cleaning. I have four guys that are going to video it. 20220707_093736.jpg

  18. I had to get after the tune up. I dropped the compression over the winter from 7.5-6.5. This took alot of heat out of the cylinders. It also makes it rich. So the car was fired up in the shop and a temp gun was used to get pipe readings. Number 2 was 150 degrees hotter than the rest. As we figured 5 and seven were cold. A few nozzle changes and it was fired again. This happened several times. We were not seeing the results we wanted on 5 and 7. We did a plug and wire change along with a leak down to verify it was mechanically sound. After two more fire ups all the cylinders are within 20 degrees. It took almost 20 gallons of well spent nitro to get it right. I fire the car on the car lift for safety. When the throttle was hit it sounded like a bomb going off. It almost jumped off the lift. Now that its on all eight at the correct temperature is sounds like never before. This will do wonders for the 60 foot times.

  19. Theres nothing like rolling into the cruise in on a big load of nitro. The car can be a little un nerving for those that haven't been around a nitro car. The sights; sounds; smell; vibrations etc become sensory over load. We fired it up later in the evening for everyone. It was a perfect summer night with thick nitro fumes in the air.
    There were alot of cool cars there. Even a street driven wheelstander. 20220709_172454.jpg 20220709_172501.jpg 20220709_181518.jpg 20220709_184934.jpg 20220709_185257.jpg 20220709_185421.jpg 20220709_185453.jpg 20220709_185501.jpg 20220709_185507.jpg 20220709_181255.jpg
  20. The tune up works. A bunch of new power is on hand. Up up and away. I see a four bar adjustment in my future. 5G2A7717.jpg 5G2A7715.jpg 5G2A7716.jpg

    Did the 60 foot improve?
    Another question, with the front end in the air and coming back down, what’s the effect on your ET?
    Third- looks awesome!
  22. Anything other than a inch wheelie is wasted power. All you need is a inch to get 100 percent weight tranfer. I tripped the 60 foot clocks with the rear tires 1.30 so its hard to tell et wise if it improved. Sure felt good.

    So, what were your times? It sure looks like it was fast in those photos!
  26. Not good times at all. I had to back out because it was still going up higher. A 4 bar adjustment needs to be done now that there is more power at the hit. 1.30 with the rear tires.
  27. Brian ,
    That right rear,,,in the first pic,,, was barely touching the track looks like .
    Man alive,,,,,what wonderful sound it was I’ll bet,,,,,the Mighty Hemi speaks !
