I was on top so I wasn't totally slacking!!!

All diesels are direct injection. The trick to diesels is to add more fuel, which creates more boost, and then retard the injection timing. If you can you lower compression and turn up the fuel even more to get more boost. That is all you have to do to one to get insane power levels out of them all at low rpm. My 400 big cam 3 cummins has teflon and ceramic coated pistons, 17:1 compression, +2 size injectors, series 4 Holset high altitude mapwidth enhanced turbo (series 3 is stock), dual fuel line kit (feeds the front and back of the heads instead of just the back), retarded cam timing -.080 where -.070 is stock, turbo boot, recalibrated fuel pump. I push 270lbs of fuel pressure (stock is 170lbs) at wot with just a wiggle of the big toe. It'll push 36 pounds of boost (stock is 24lbs of boost) at around 2200 rpm which is 601.2 fwhp. It's getting 500 rwhp and the pyro won't get over 750 degrees! I can take off from a dead stop on the high side of the transmission and use the top 5 gears. It'll spin the tires going around a corner on dry pavement if you hammer it. It drives like a car and is fun to drive. Pulling big loads is a dream but it does suck the fuel. My mpg's went from 8 to 5mpg.

Now I feel like Cozy z Cole does every daY!!! Work it baby!!!!

My sister got me a birthday card that said, "Do everything your not supposed to do!" So, I DID! :lmao:

Thanks guys. Plans, well, I have some engineering plans to do today. Going out with the new woman, kids and her family tonight for steaks. Old GF wants to rock my world but I think I'll pass on that one. LOL

And here I thought if you wore a timex it would never quit! Supposedly they take a licking and keep on ticking. I have often wondered what happens to the mass and how much energy it would take to get to the speed of light. Probably never know I guess. I asked Scotty in engineering and he said a potload of dilithium crystals should do the job. Too bad I'm fresh out. I knew there was a good reason to build a fast z!!!

That was rich!!!!

:lmao:

Your the winner!!!! I only have 6.

Keep on technical track here please.

LOL, run 14:1's, roller cam, AFR 220 heads, run 9's.

I think mid to high 13's is about right on, which is pretty darn quick. There is no debate. It's all about preference.

Stay away from it!! Give me his phone number too.

Nope, haven't lived that long and was planning on not living that long. Besides, the z proves that theory wrong, it's always not in motion except for brief periods of time! :lmao: Space is not empty. Most people find this statement surprising since we generally think of space as a vacuum. To a certain degree this is true, but space is not an absolute vacuum. It is filled with very thin electrically charged gas consisting mostly of protons and electrons. The gas is so thin that a thimbleful of air holds as many atoms as does a cube 2 miles on each side in space. Pretty thin, but it is still there.

No such thing as too much power!

What you heard is complete bunk. Everything that has mass has gravity associated with it, that includes yourself and everthing on the planet. It is a calculatable gravitational force. Space is zero vaccuum, there is not much there as far as gasses go. There are other planets, solar systems and much much more. Our planet revolves around the sun whose gravity keeps us right here where we are. The z's around here have gravity and they affect my wallet, money seems to fly out of it and go right into the car, never to return.

Very Cool!

Based on ET that 13.8 calculates to 263 rear wheel horsepower and the 12.4 calculates to 363 rear wheel horspower. I doubt that is stock 302 by any means as that would make that engine making about 300hp at the flywheel, which is almost 100hp over stock HO motor.

Works great

You mean tune and then turn it up to 10psi and tune some more, correct?

Memory foam, I have alot of it. Works great, starts at 3 inches and you can compress it down to about a half inch. I cut it on my band saw about a 1/2 inch wide and glued it on the tanks and just stuck it in the core of my pete between the A/C and the Rad. Been there for several years now.

Looks good, like it's ready for more boost!

I think for this thread we need to stay on track. He's not talking the fundamentals and intricacies of fluid dynamics to describe reductions in drag and improvements in downforce. And as you get closer to the skin of the car at any point you will always have laminar flow, just depends on how small of a thickness your looking at. We need to keep it fairly simple and for the most part he's on the right track IMO, so let's look at the general areas of HP and LP and how to route the air to make it work. We will leave the hair splitting to another thread. Sealing the IC, TC, and Rad are all good ideas and well worth the effort. Foam works fairly well sandwiched imbetween them in small strips.

I believe it has to do with combustion chamber shape, elimination of hot valves, diluted intake charge, etc.

I have seen that before. Poor quality valves. Ferrea had that problem when they first came out. I built a 434" sbc alky sprint car motor with brodix heads and those ferrea valves and at the first race during hot laps the engine started missing, valve adjustments were tight, re-set them and car went out again only to come back with the same problem. Tore the engine down and the valves were "tuliped" The center where the stem meets the head had pulled and the valve length was was alot longer. Odd problem, but was common back in the early days especially with stock valves and lots of spring pressures. Switched to Manley sever duty valves and no more problem. Switch valves and your problem will likely go away.
