The diesel engine as a viable performance option

First I’m primarily a gas racer; I cut my racing teeth as a Competition Eliminatorcrew member, and racer. I get a woodie when I put my foot on the throttle of a 11,000 rpm small block.

I was stranded without a affordable and competitive engine program at the end 2001 season, after a fairly successfully 5 years of campaigning a D/ed with a Splayed valve V6. I stumbled in to the diesel performance world, and found it to be a new found passion.

The diesel engine development curve is where the gas world was 30 years ago. I speculated it would rapidly catch up, and it’s coming along, there are a lot of inovatators in the diesel couminity .
When I first started with diesels, mentioning cylinder head and cam development was laughed at. They stated that boost would overcome it all. 6 years later the shop that I begged to do my head, and build a sheet metal manifold has a 3 month waiting list to get a head and manifold.

So is the diesel engine as a viable power plant for a muscle car, bracket car, or even race car .
I don’t mean the typical smoke belching engine, but well refined engine programs. The diesel engine has made huge gains in this arena with the advent of electronic common rail high pressure with 20,000 to 30,000 psi fuel systems.
With the CR systems you can tune around destructive peak cylinder pressure as the engine goes thru peak torque. The solution to this before, on mechanical fuel systems was to reduce compression ratio, killing low eng cylinder pressure, and this worked on all out engines, but killed bottom throttle response. These lack of bottom end , also effected the AR selection on turbo’s

The advent of cylinder heads that in effect doubled air flow (Cummins stock 144 CFM ) ( Duramax stock 140 CFM ) to both heads flowing close to 250 CFM on streetable heads and 300+ CFM on all out race heads.

Cam design, which I made one of my pet projects, was way behind. The major player would grind BBF RV grinds on the Cummins 54.5 mm core, the events were to big , and with way to much overlap
Problems was the turbo diesel engine cores were on at best 102 to 106 LSA and the overlap was one of the greatest no no’s on a diesel . The diesel engine has little scavenge with 1.2 to 1.5 boost to turbine inlet pressure ratio’s . The tipical street cams would open the intake 10 ATDC and close at 2 or 3 ABDC . I use a cams that is 230 230 on a 116 in at 116 . and do it on 60 mm cores


So to the latest in Chevy Duramax engine for a street engine
First forget the huge injectors, twin pumps and compound turbo’s. A stock short block Duramax with a good cylinder head, and cams program will breath well, and make 600 hp and 1000 ft lbs of torque, and rev to 5000+ rpms and last forever. The great part about doing the heads and cam, on a entry level engine is, that now this good breathing engine will make a good power curve at low boost levels. The great part is no need for an intercooler at this boost level. Just use Water injection on the street.

This engine in a muscle car will run good, smoke free, and get 40+ MPG on # 2 diesel fuel. Go ahead and put a good set of rods in the motor and the hp level is close to 1100 hp with nitrous , which doubles as an intercooler.

Here are some pictures of the NX Mustang and My Dragster and their engine programs based around the Dmax diesel engine.

Oh and I love this forum, the knowledge level is humbling.

I am a TDR and DTX guy, this has been the most amusing thread. I'm glad that people know Greg and can call him out on his b.s. He thought he could fly under the radar on the Bullet :smt102

So in honor of probably one of the biggest douchebags in the diesel world my sig will do the talking.

I don’t know why you bunch of douchbags if that’s what your favorite word is, are continuing this fraudulent posting. It’s evident that this mob action is but a few individuals that are so unsecure in their scrotum contents, that they must attack the genuine deal. If you look at the facts contained in this thread, its very evident that Greg has been there and done that in the motorsports world, and these individuals just have street trucks, that make you squeal like a girl. I guess that these individuals are wanting guys riding in their trucks that are more like girls , therefore they don’t feel as gay. The goal is to discredit Greg with Propaganda. You know the saying, tell a lie often enough, and its starts being called common knowledge. I am not Greg, and really don’t care if you think I am, just tired of watching this fiasco unfold. I have talked to a few people in the diesel business, and they had nothing but positive feedback from the experiences with Greg. He is well respected in the competition eliminator community as well. I talked to the people manning the NX booth at Sema, and they had nothing but positive things to say about him as well, as did the guys at the ARP booth, both were proud to be associated with him. The bottom line is once again 4 or 5 nobody’s are conspiring to make Greg look bad. These individuals are scum of the earth , and will not reap the rewards of their endeavor. The owner of NX told me that the Dragster was a partnership between he and Greg , and Greg was racing the car very soon. He also explained that He was confident that the car will run in the 6.70 to 6.80 range with the power now avalable.

Greg sent me a message that this thread was not worth the sweat off my balls , and ask me to please butt out , so I will respect his wishes .

I must admit I do not really understand how anyone can stand to benefit from this. Surely we all are involved or at least care enough about this industry to not want to be looked at as most have acted in this thread.

I guess I dont have the energy to expend by disliking someone else this much or try to defend myself vs the people who do seem to have the energy. While I am all for a little "roasting" this is just amazing. I do not mean that as a compliment.

I would like to add that NX's opinion is what we post and what we say. I would appreciate if both sides would leave out the " Mike Wood said this" "NX said that". If we are worried about what anyone one thinks of us we will post. I appreciate that people have not really drug us into this too bad

As said earlier I will be posting in compD. I am by the way, the only person who posts for NX with any real frequency. If you guys have any questions on any of the sites. Feel free to pm me or post. I am of the opinion I would rather have people talk down about me than compromise my own professional attitude. So I will not really argue with anyone. I am happy to trade information and even disagree at times. Arguing is not helpful and a waste of both our time.

Graham.

You have to love the bullet right?

I believe there is little doubt that these two people are one in the same. My biggest problem with the whole JP persona is he is pretending to be retired Air Force, which is a huge insult to the brave men and women that keep this country free so scum like this can lie and get away with it.
Also, If JP is a real person, why wouldn't he want to take five minutes to meet people that could easily clear his name? Just doesn't make sense.
I really can't imagine NX wanting to be associated with people like this. Weather you believe it or not, the type of people you associate with says a lot about who you are.

John Preston, I offered to verify your existence if you could have stopped by booth 23416 at SEMA. If you stopped by the ARP booth, you were about 25 feet away from me. We were next to the Meziere booth, and the ARP booth was across the aisle from the other side of the Meziere booth.
