Competition Anyone Running a "Comp Cam"????

[GreenB]

"The new build HAS MANY enhanced internals including pistons, rods, cam, and cylinder head development, along with some fillers and additives. ( couple of fun buttons for you slow fellers like Sled Puller) The new build should put Duallie's -duallie solidly in the 11's... . which aint too shabby @ 8000+ lbs. "



Duallie,

Out of curiosity what kind of pistons and rods are you using?

Pistons and rods are vastly different then the 98. 5 pieces Different design on both.

Care to mention which manufacturer for them? No specific details though.

I'd really rather not:-laf ... ... ... Some things need to remain in the garage..... But I've researched these pieces for some time, things like bowl design, how the injection cycle works with these bowls with the right injectors and pump delivery psi's, weight, strength, and other factors such as performance coatings for durability ect, torsional harmonics in the rotating assemby, different bearings and mods there as well, even the ring pkg.....

I think that's enough info to work with ... .

Hey RD!!



Nice jungle jim!!! :-laf



Whats the estimate on a finish date for that one?

 

[RacinDuallie]

Hey RD!!

Nice jungle jim!!! :-laf

Whats the estimate on a finish date for that one?

I wish it was done yesterday:{ ... ... The chassis has to be "tabbed-out" then body mounted, then its in my hands for plumbing, wiring , engine program, trans, ect. ect.
This is a ground up build up, built for Pro Mod Diesel Racing, I believe its the FIRST true ground up -build up- for Pro Mod Diesel Drag Racing, not a converted ex gasser... .

I may- slim chance- still run the ol duallie, along with this new project. But for right now- this project has my fullest attention... . Oo. .

 

[COMP461]

Been busy, Jr.



COMP has posted his own numbers.



When he posted over the winter his FLYWHEEL HP numbers, then a few days later, several legitimate Diesel drag racers posted theres at the WHEEL, any gasser trash V-8 rev-gain technology he is using for his engine program has got to be flawed. Look at his time slips, nice. :-laf



Like I been telling him all along, this is a 6 cylinder Diesel, not a small block Chevy.



How can people who do worse when they build a new engine, still sell you guys parts????????



Oh, and about half a dozen DHRA Mod pulling trucks are not using COMPs cam, and have at least 2 more HP than he does. And the Super Street class. And at least 2 in the Street class. :-laf

Sleddie, I noticed some of your Hero’s up on the mountain using 3 or 4 cans of ether, and boiling transmission fluid to try and get them to spool, Poor Old Tractor Pullers Trying To Drag Race

 

[Sled Puller]

, Poor Old Tractor Pullers Trying To Drag Race

I think its more like, "Poor Old Flatlanders Trying To Race At Altitude. "



Who was there? I have no idea, this is the hot season for the real Diesel sport, and I haven't paid much attention to racing. Like you always tell me, "Go drag something heavy... . " :-laf

 

[banshee]

Hey Mr. Know It All (that would be you Compy),



That's what you get when you're not huffing in an entire bottle of nitrous per pass. I'm sure their chargers would have spooled well had they been running 4 or 5 solenoids just like you!! Nevermind the fact that they ran the 2nd fastest truck time there

COMP 461:



FWIW,. . I was at the "ATS Truckfest" with my buddies Jimmy and Dale Smith who towed their Scheid Diesel/ATS Diesel/Valvoline/CORSA Sponsored Dodge DHRA Pro-Street Truck and I am assuming that in your statement above it is their truck you are referring to. I was there with Jimmy and Dale helping them in the pits and down at staging so I know what did and did not happen there.



AS USUAL COMP,... ... . you have AGAIN "let your mouth overload your a**!"

I am going to state some facts here to let everyone know you are again WRONG in your statements of what actually happened there.



#1. ) You stated: "I noticed your heros up on the mountain using 3 or 4 cans of ether and boiling the transmission fluid to try and get them to spool. "



FACT: While ether was used by Mr. Smith to get the truck started AT NO TIME was there 3 or 4 cans used!! Just another exaggeration by you, as usual! There was enough used to get the engine started and that was it!



#2. ) "and boiling transmission fluid to try and get them to spool. "

AT NO TIME was the transmission fluid in that truck to a "boiling point" as you stated! WRONG AGAIN COMP!!!! In fact, the temperatures were very well within the "normal" range as evidenced by the CORSA system in that truck. If you or anyone else here doesn't believe that, Jimmy Smith would be glad to show you the computer readouts and I am sure Clint Cannon @ ATS would tell you the same thing!



While it is true that their truck was having some problems spooling up in the high altitude, many trucks there were in the same situation and as "banshee" so eloquently pointed out if Jimmy and Dale Smith had the amount of nitrous you did they would NEVER have a problem spooling ANY turbos on their trucks!



Also FWIW and "For the record",... ... . when they drew you in the first round of eliminations and were unable to go to staging that WAS NOT due to any type of spooling problem. In fact,... . it was a leaking #3 fuel line on the very top of the P-Pump due to a cut O-Ring. You are always harping about safety on this website and due to the amount of fuel leaking THAT was a safety issue and the NHRA/Bandimere officials agreed with that!



When you came into Clints garage at ATS and came over to Jimmy and Dale's truck I only wish you would have opened your mouth then so myself and them could have discussed your "opinions" and "observations" with you then!



Those are the facts and they are unrefuted!!

This was not aimed at you or your truck, but the entire concept in general of Sleddie cheerleading from the side lines, about the power of the so called big diesel engine shops and how much power they could make in comparison to the completely different power required to drag race. You can make all the power on the planet, but unless you can race in a real world environment, it is ineffective.



In the normal real world of drag racing, Auto Start is used; this is to keep the pace of racing at something more then a crawl. The tree is preset to activate on a random amount of time, not when every one is spooled and a starter drops the tree. A competitor has 7 seconds to complete staging once their opponent has staged. There is a lot of talk going on about the amount of time it takes to spool these pulling type motors. I realize that some people at these races are not there to be competitive at race, but to put a number on the board, remember if a competitor is timed out for taking to long to stage, a red bulb will go in their lane and no time will display.

Sleddie has been his usual abrasive self, and vehemently calls attention to what he perceives as short comings in our motor program. I see a distinct difference in motor programs, and the intended use. I believe that the message rang loud and clear, and it is evident in the volume of calls Ray has fielded, and the orders that are coming in.

COMP 461:



I am afraid I will have to disagree with you again here.



First off, it is my opinion that you were/are "aiming your comments" towards Jimmy and Dale Smith's Pro-Street Truck contrary to what you said in your most recent post above. I was not down at staging for every truck that ran, but for the times I was there, they were one of the few that were using ether to start their engine. There are obvious reasons for that, which I am not going to go into detail here about. If a person understands the concept of how a high performance diesel engine works with lower compression, then they should understand the whys and how of why ether is used at all.



You mention "real world environment" in drag racing. Well COMP,... . let me give you some "real world figures" on Jimmy and Dale Smith's Pro-Street Truck. At "Thunder in Indy" Jimmy ran a 10. 5 @ 132 MPH and if my memory is right had a . 200 reaction time on that run with Indy using the . 000 time as perfect there. IMO,..... that is a very good time for a 6280 pound truck and Jimmy's reaction time is very good also. For the other members here, you had a . 120 reaction time at Kentucky and Keating had a . 233 R/T in his run with you. So,... ... Jimmy Smith is very close to both of you and IMO had NO PROBLEMS spooling and leaving the staging lanes at the start. The fact is his truck has not had these "spooling problems" you mention since Clint Cannon and his ATS Crew have worked on the transmission to improve the earlier problems they had. So,... ... ... IMO Gene (Sled Puller) is right in what he is trying to say to you. You seem to call any Scheid built engine a "sled pulling engine" when in fact while the engine in Jimmy and Dales truck has some similarities, there are also many internal differences.



I also don't need an education from you on how the lights etc. work at a drag strip. I have raced vehicles since I was about 17YOA and I know how things work COMP!



You are right in in saying there is a "distinct difference in motor programs" from each diesel shop/diesel engine builder. You have a good program with the guys at "Ray Mac Racing. " But Jimmy and Dale Smith also have an excellent program going with Dan Scheid @ Scheid Diesel. Don't EVER doubt the fact that Dan Scheid and his great crew of technicians and engine builders know how to make power with a high performance diesel engine reagrdless of what you think COMP! And what makes them really great IMO is the way they handle themselves with customers and fans all across the U. S. When have you ever seen Dan Scheid come on this website any other to "toot his horn?" Answer: NEVER! While Dan may be somewhat new to the drag racing with the diesels I can promise you once all the bugs are worked out on his dragster and Jimmy and Dales Truck look out!! IMO, he has proven this in the sled pulling classes having won many titles etc. with his engines in not only the Scheid Pulling Truck but also many of the other top competitors there! You also say Ray has "fielded many calls" in reference to your truck! Well COMP, I can tell you unequivocably that Dan Scheid fields as many or more calls as Ray does!



One last thing,... ... ... . a fan overheard you criticizing your very crew from "Ray Mac Racing" and related to us and others for "sanding or grinding on a delivery valve" in your race truck! Not too professional IMO COMP! Do you to care to comment about that? It's funny that these are the same guys you praise, but then tend to publicly criticize them in earshot of fans walking by! If any of that is true THAT is what I am talking about when it comes to you and your relationships with others!

Comp, I smell something. I think you stepped in something. Check the bottom of your shoes.....

 

[banshee]

Hey Comp,



Have you taken the time to run the math on the HP being produced by your truck and the Scheid powered Pro Street truck based on 1/4 mile ETs and vehicle weight? You should... . because you're waaay off the mark. LOL. Imagine if they actually turn the nitrous system on with more than a . 020 jet!!



What's that comment supposed to mean Scott? Are you implying that John_P is lying or BSing about something? Please come clean!!!

 

[sbentz]

I am absolutley not implying anything about JohnP or the Smiths. As a matter of fact, they are probably the nicest people we have run into while diesel drag racing. These guys would give you the shirt off their back without batting an eye. For example, on our first pass on Saturday, we accidentally lined up against them and ended up running against them. They had a little problem staging and many people said "they hung us out to dry. " When both cars launched, Jimmy's crew was already over apologizing to us about how long it took to spool. They could not apologize enough when we got back to the pits. JohnP and the Smiths are the most generous and sincere people we've been around in a long time. Again, I was NOT implying anything about JohnP or the Smiths. I hope this clears up any confusion.

I read Scott's post to mean "Comp, you have created a mess for yourself".



Maybe I'm wrong.....

 

[BIG BOB]

I know that most of this thread has been directed at racing or pulling cams, and not to hi-jack this thread, could someone tell me about Scheid Street Cams. Thanks BB

 

[John_P]

BIG BOB:



As I recall, Scheid Diesel now has around five to six different camshafts depending on what you are looking for. They start with the milder "street cam" and go up to their full billet race cams for sled pulling or drag racing. You can call Dan Scheid or J. P. @ the Scheid Terre Haute Shop @ 1-800-669-1593 or Mike Wood at Scheid Diesel (Effingham, Ill. ) Shop @ 1-800-669-1934. Any of these guys can help you decide what would be best for your particular application.



Hope this helps you some.

The Cam I have been using, and working on, are done on a CNC Cam grinder, these are ground by the same people that grind most competitive Pro Stock teams. I can go from mild to wild, on more then just duration and lift. Most people use masters that IMO are very Lazy. This laziness causes the cams to have big seat to seat timing, and this bleeds cylinder pressure. Valve Crack is the point that the valve is first opened and allowed to bleed cylinder pressure this excessive timing is IMO the reason for the laziness and the difficulty in quick spool. .



The whole concept is to retain cylinder pressure , but move air , this is what you are seeing in the dramatically quick spool, is the result of air flow management , and not having to build big boost numbers to push air through a already restrictive port . These cams wait till the last degree and rapidly accelerate to valve open to move the maximum about of flow with out loosing cylinder pressure.







Now how dose this relate to the average street guy wanting the benefits of a cam program. Simple, you go with a cam that under these conditions is short enough to run with out cutting pistons, but will increase air flow, and give you that quick spool you want in a big charger truck

Where are you going with all of this Comp??? What your trying to say is your betting on winning race's against faster trucks soley on them not being able to spool on time??? Of course this is when they use Auto-Start, oh and for all of us dumb-***** on here the "tree" is the little thingy with the lights on it.
