Competition Dhra Rules??

[Kyle03D]

Last time I checked those old mechanical engines were on top?

Something change lately? :-laf

Great, no need to change the rules to try to limit duramax fuel.

it wont be long and the dmax will take the crown, if only we had a efi live for our trucks they would not touch us :-laf

That EFI Live looks to be a very hot ticket right now.

Woulda, shoulda, coulda, do yu believe these kids? My daddy's gone whip your daddy. Thank the good Lord, Brandon don't talk it. He just does it.



And these "newer" truck's are getten beat with old 12 valve engines.

... oh yeah cp3's arn't injection pumps they don't inject nor time any fuel delivery to the cyl.

You might as well not even waste your time on this one. "Everyone" knows that adding 2 cp3's is the same as this. I mean it's gotta be right you know double the fuel.

 

[JFaulkner]

I bet some of this whining is because Mfunderburg's Fiance handed it to a bunch of street trucks in Hillsboro. Funny I own a Dodge and I don't remember mine coming with a box of tissues, my guess is yours didn't either so stop crying. :-laf



If your not going to allow 2 pumps then don't allow modded ones! Both are out to accomplish the same goal just different designs.

 

[nwpadmax]

I totally agree. Give everyone as much fuel as they want.



If the 12 valvers can run whoopass p-pumps, let the electronically injected trucks have 2 CP3s.

or you could p-pump your 3rd gen.....

That costs WAY more than the dual cp3's. Especially since Ted is the only one who makes the front cover and he's not having a good year with injection pumps, I'd bet the price goes up with each bad pump!

 

[PToombs]

What the helll is a cp3? Sounds like something from star wars... dang internet pullers...

Yeah, I had a cp3o, but it was too much trouble to time. I went to twin R2D2's and get more ewoks per gallon, but the fuzz is killin' my filters! :-laf

Well it looks like Jfaulkners rules are run what ever you want as long as it is a certain turbo charger size then your good. I guess the teching issue is solved.

Or they could use your "Helen Keller Rules" and as long as they can't "see" the mods it's ok. 13mm plungers are ok, 5k gov springs are ok, I can hide nitrous also is that ok since you can't see it? I suppose pusher pumps should be "illegal" also, since just like an extra cp3, your keeping the fuel pressure up. What about a pair of really heavy shoes? Do they somehow give an unfair advantage with the "lead foot" disease. I bet stickers add too much power also.



I think the D-Max guys are right, this seems to only be an issue since they've caught up.

 

[zstroken]

The idea behind stock appearing is it makes teching easier, Like I corrected myself ealier if your would read all of the posts completely, I said that dual CP3's are ok, but next it will be this, and then that and then we allow this, and etc, etc. People keep complaining about how unfair tech is. I have never once complained about how the tech went. Once you start allowing stuff that is non stock appearing, the teching job becomes more and more of a nightmare. And yes even 14mm plungers would be ok, and 5K springs are ok, I said modded CP3's are ok didn't I?? I mean if computer programs can run the RPM limit up, why not a set of cheap springs, heck use a piece of pipe in place of the springs. I think your getting the wrong idea, I am not against rules that are evening the playing field, just trying to keep from having a rule book that is 1000 pages long, or all of these gray areas for people to assume this and that.

 

[JFaulkner]

I understand what you saying. However it doesn't matter which forum you on everyone jumps all over the dual cp3 idea as being "unfair" but are "ok" with the modded ones. If the modded pumps are so good (one place is claiming 230% over stock for a mere $5k... . Please!!) then what is everyone that's "pro-mod pumps" worried about? Surely a 2nd stock pump could in no way compete with that! :-laf It just seems totally unfair that if you want to keep within the rules and your rail pressure up you only have one (very expensive and unproven) option.



Keep in mind the injector controls the amount of fuel not the pump. If doubling the fuel was as easy as adding another pump then why bother with bigger injectors and programming? Why. . because it doesn't work that way.

 

[zstroken]

Well to even the playing field since the CR can have variable injection timing, multiple shots per combustion, changes shouldn't need to be made then. Time will tell I guess. Maybe the old sled meister is reading this.

 

[jwilliams3]

Dan,

Please list for everyone your ideal set of rules for the DHRA street.

 

[zstroken]

I pretty much have somed them up. I don't care if there are dual CP3's, but as I said, you start allowing this, then you start allowing that. It brings up whining and tech issues. Well your allowing such and such to run dual this, why can't I?? I understand that stock appearing could add cost, but who knows. As you have found out the 2. 8 rule pretty much exceeds the stock drivelines power handling capabilities. The Dmax boys are twisting driveshafts and I think some of them have broken axles, the cummins are breaking axles, and output yokes off of transfercases. Maybe if we go to a 2. 6 rule then we would eliminate the need for dual CP3's?? We could also eliminate the need for the expensive driveline upgrades. Have a W/S class, and that is it, no non stock appearing items period, no pushers, intake and exhaust mods are the only non stock appearing items. Of course boxes, injectors, programmers are allowed. Stock Rev limit. Rear ujoint shield



Street stock appearing, except for intake, exhaust. Some sort of turbo limit(I think 2. 8 is plenty big), upgraded low pressure fuel supply systems are allowed. 4-4500 rpm limit(??), all ujoints shielded, all drive shafts looped. Since people feel they need dual CP3's let them have it. Same tire rules, transmission rules, stock block, etc, etc



There you go folks, tear it apart!!

can work stock trucks have guages?

 

[Tcolesanti]

What's the deal with these modded CP3's? Why are'nt they working? Are they grenading or not tunable or something? I have heard this alot lately and was wondering why?

I mean those 3rd Gen's at May Madness put down like 900hp and were street driven and towed 40,000lbs there and back and they don't have dual CP3's just modded ones right?

Yes they can.
