NX Dragster new pistons

comp.....youve by far surpassed the title "douche bag"
honestly, ive never heard you do anything but speculate and critisize everyone else thats going out and actually doing what they want to do and advancing our sport. all i hear from you is your chops flapping together with worthless babble. plainly put, youre a nobody in my book because i havent SEEN or even HEARD of you doing ANYTHING to help this sport.
Put your f*cking money where your mouth is or get off the high horse dip****.

sorry, rant over................
oh and im sorry if we cant be friends but i honestly dont care good buddy lol

just curious, who are you and what have you done? :confused:

Greg may rub some people the wrong way, but the guy has raced professionally, ol' Banks hooked up with him, and he's still in the mix rubbing elbows at the top of the heap and getting stuff done.

he's done PLENTY to help this sport!

what have you done? :confused:

X2. A lot of people dont like Greg, but he has seen and done a lot for diesel racing. So he has a big head, you would too if you were in his shoes.
 
I have to say this to all you Haters... the NX dragster has came a long way since last March when I helped Greg pick it up in Witchita Falls to this weekend. Just like Dalpilot's project is taking time. Any real project being bilt by a normal man will take more time than everyone expects it to take. It's only a matter of time before the NX dragster shuts alot of people up. The car looks more refined as does the engine program. It's coming together people. Talk BS now because next season it's going to happen for real. Greg's just making sure all his i's are dotted and t's are crossed.

Come on, we all know Greg is just out shopping for a gold plated bullhorn to too his horn. LOL
 
thought I would show a few pictures of the piston and rod combo before Tommy stuffed then in the motor.

The bowl is incorrect in so many ways. I cant believe it; you went further in the wrong direction than you did when you used CR pistons in a P pump application. You always keep me laughing Greg. Good luck IF that rod is aluminum too.
 
I have a lot of questions about this whole setup too.

The problem is, if it works, then everything I think I know, is junk.

And I'd have to punt.
 
I'm a nobody and I don't claim to be anything but that. I work a normal day job like everyone else and help my friends out and try to advance the sport in an area that the full diesel trend hasn't quite hit yet. I help people like chris when he brings the nhrda to topeka for the first drag big drag event around here, help a buddy of mine at a certain shop in kansas, and go out of my way to help push the diesel thing along with the means I have in front of me.
I just don't like the "my **** don't stink" attitude and running chops when you're still watching from the grand stands instead of going out and doing anything. I build my own rigs and don't claim they're the top of the list as they're not. This is my first pull truck built just for it but I can lay claim that its all mine and will be a lot of fun. I have helped on some things that have and will advance this sport and the power we make but I will not take full credit as I'm not the creator. Ill just keep lingering around doing what I love and knowing what I know. I help when I can and keep the sh!t straight.
I like ya forrest and you're a great help to people like it should be, I'm just not a big fan of hogue and his chops.

Then if you know that is so wrong how about you come out with something to prove him wrong? :poke:

Pistons of this design are not new to the performance Dmax world or the performance diesel world. Very similar to the bowl design used by Arias for there Dmax pistons. Very similar to the bowls in pistons Arias makes for Schieds, Haisley, GMS, and Enterprise. They must all doing it wrong to?????

Mike Woods NX Mustang runs this design piston. I can tell you first hand I was very impressed. Why? Timing! Just like when you change cylinder heads on a gasser to ahead why a much better chamber. You need less timing to make it run. I have considerably less timing in the Mustang tune up then I do in the Z28 Dmax. The Z28 has a LBZ style bowl. But the timing curve out of the Mustang does not work well in the Z28. Both Tommy and I attribute that to a better chamber design of the pistons in the Mustang. Which runs 9.7s with virtually no smoke.

I guess we me must be doing it wrong. Because this engine has out run and out lived the conventional piston design engine that was in it before.


Also on another note. As a person of Eastern European decent I find you’re continued used of the screen name Soup Nazi repulsive and classless. I as a young man I listened to the stories of my great grand parents of the Nazi take over and the atrocities that ensued from the take over. I find it odd that a supposedly educated man as you would want to tie himself to such regime.

Off my :soap:

well I suppose that's fair :o

I've just talked w/ Greg a number of times, and he's helped me out a few times, and he really does have a passion for this stuff. And he is building a dragster

JFC..... its just a reference to one of the funniest and most popular sitcoms ever.... don't get your lederhosen in such a knot

LOL

IIRC, didn't someone kinda give Don that screen name? He used to be on here as himself, I thought.


As for the piston and rod....

The bowl shape, I'd like to see more discussion about it. It would be nice to see a cross sectional view of it versus the re-entant bowl as a function of crank angle and spray pattern.

John, just because "everyone" is using it doesn't convince me yet. If we went with what "everyone" was using, we would all be using Banks' junk.

Secondly, you take a 1.375" stock wrist pin and trim it down to that petite little thing? Wow. The static stiffness is far less than stock. So it'll be interesting to see how the bushing and pin make out over time. I could see hollowing out the pin and keeping the stock OD, that would still be stiffer than this.

And for the rod, without seeing the FEA, only experience will say how well it will work.

No one seems to have much good cylinder pressure data, so it's hard to say what's acceptable. This just looks awfully gasserish to me.

I mean, hey, if we can run BBC parts, zippidee do da...!
 
All I ask is that you be a profesional about the things you do or say. Hell, it gains a lot more respect and better yet, keeps the respect people have for you. Settle it on the track and respect your competitors. There's no reason to be a d-bag if your claiming to be at the top of the game. Look at gale, he's done big things and what not but he acts like a stupid f#ck in his adds. Real data (its hard to get actual data lol) and customer approval is what sells products, not your retarded mottos in your 30 page adds.
Basically, respect your competitors, shops, and especially your fans and they will in turn do the same.
 
Yeah, I was given the name. LOL. Im proud of it and it fits somewhat.

Just try and get the top secret parts and products out of us. Your results will most likely be very similar to the poor guy who had his soup taken back.
 
The 1.156 .300 wall tool steel pin is far stronger then the stock dmax’s pin.

This is the same pin that lives at 1000 hp per cylinder in a Top fuel engine.
The data on cylinder pressure dose tells a story, if you have the ability to look at it, And most that do are not sharing it.
The results are what you are seeing in this design. I started years back by going bigger and bigger with the bowl, in the Dr Performance truck and the timing requirement became less and less.

With Project X , I went with the bigger bowl and picked up close to 100 hp with the same injector . The Ross pistons I speced for my 5 liter Cummins Land Speed piston, looked just like this, with out valve relief’s .


As to aluminum rod , this is the same rod design , that withstands 1000 hp per cylinder as well.

. The results from this 1000 gram of bob weight reduction allows a greater stability in the rotation assembly, and the ability to internal balance , taking 10 lbs off the balancer alone and a total of over 20 lbs off the total assambly .

In any case the results will speak for them selves , The dragster will be ready after the first of the year, its just a lot of money.

I have zero financial backing on this car , and every dime that gets spent on it come out of my pocket. Sure we get parts , but that is a small part of what it takes to get to the track. .
Most of my projects take a few years , as did the Predator truck when I took two years to build it, in the back of RayMacs shop .
I have very little help on that one as well spending a lot of money out of my pocket as well .


As to what I have and am doing in the diesel world , This year, I sponsored a purse for 4 diesel specific drag races . Provides a truck to race for the eventual the winner of 2 of those events.
I sponsored 4 dyno event prizes . Went to 5 events including TS . Was invited to Displayed a Diesel Dragster at the front door in spot number one at the PRI show .

Along with Hot Rod Drag week , The Texas Mile both with a diesel Powered Vehicle , so drasko who ever you are.
get your facts straight , and quite being such a sheep and wanting to make points
 
Greg, you missed the point entirely on the pins. Strength and stiffness are not the same thing. Modulus of elasticity does not vary much with alloy content, period. So you can heat treat it all you want and add alloy all you want and it will not get stiffer. You should know that.

That pin will deflect more under load than the stock one will. It's not a debatable issue, it's statics 101 for freshmen. Because it is strong, it probably won't permanently deform, but bend more it will, I guarantee it.

Now, if the deflection is acceptable for a race engine, then OK, what works, works, and the original deisgn is way overdone.

I just see a lot of force being put on a small pin being held by 2 aluminum parts, and I wince. You might not, and that's OK. Only experience will tell.
 
wow Greg. I'm impressed, did a 12 year old help correct your grammar on that post? It's an 7 out of 10!


Sorry, had to :)

delete if you will.

How about this....can you please explain this to me more?

What do you mean by "less timing" to "make it run"?

Are we talking a few degrees? Because that could be explained by engine-to-engine differences...you know...pin locations, gear accuracy, absolute cam timing, etc., all that.

Or are we talking more?

What other factors could be contributing to that? How about injectors?
 
Top fuelers make under 8000 HP now with the 90/10 mix or even less at 85/15. Also, their tq is 6000 ft lbs or less. Instead of TQ being double the HP like a Diesel would run, the top fueler is actually lower than most gassers tq/hp relationship.

The top fueler only has a brake mean effective pressure of 80-100 bar. Lower than many Diesels. Its a relationship between RPM and power produced Greg.
