Engine/Transmission (1994 - 1998) cam plates

[Dieselholic]

why do the piers and tst kits only boost the numbers up by 15hp and 65 tq??? (these are for the emissions legal plates) Sounds a little wimpy to me. but then again my current daily driver only makes those kind of numbers downhill

 

[JGheen]

What plates are you refering to?? You can make more or less power with a given plate depending on it's position under the AFC housing.

 

[Dieselholic]

im talking about the tst #12 for 96-98 manual

sorry for not including that part

 

[JGheen]

A #12 plate is a pretty mild plate. Those power inceases sound about right, but again, it depends on where you position the plate. Full forward should give the engine more fuel and power than advertised. I bet those power and torque numbers are given when the plate is replaced in the exact same position as the stock plate.

 

[Dieselholic]

why is it only smog legal to have such a mild plate then?? i guess no one in the EPA drives a bombed CTD

 

[JGheen]

What do you mean?? Out here in California, diesels are exempt from smog. And I thought that this state had the worst smog rules of all. Where are you at?

 

[Dieselholic]

it says on piers website that only 230/605 cam plates are emissions legal for highway use in North America.

[JGheen]

Where are you located?? And what pump do you have 160, 180 or 215 hp??

 

[Dieselholic]

ill have a truck soon, preferably one with the 215 pump and im in PA, there's no diesel emissions testing here as far as i know but i dont quite understand that little warning on piers website about emissions

 

[JGheen]

I wouldn't worry yourself sick over it or worry about it period. Call Peirs and find out, maybe it's a Canada thing being that's where they are located. I am running a #10 plate and blowing black smoke all kinds when I stomp on it and cops around here don't seem to give a rats a$$ cuz there is nothing they can do, it's exempt.

The Piers web site is right. Now if you want you can bomb away but check with your local laws about opacity testing as in Nevada. In Cal. we have no testing at the present time.

[Driftwood Ram]

Some parts of Washington State also test

We may have a right to smoke , but eventually we'll lose it if we insist on it.



Smoke is partially burnt wasted fuel/HP in any case and one day the car behind us will be driven by someone connected to the smog busting committee for our particular state, when we decide to exercise our right to smoke.



In any case, most States/counties/cities have smoke abatement regulations which can result in a ticket.



I say save our smoke for the race track and dragstrip and concentrate on turning as much fuel as we can into power .

Try like 15 hp but 165 ftlbs of torque, not 65.

Stock 96-98 5 speed 12 valve was / is rated stock at 215 hp / 440 ft lbs of torque.



The #12 plate is 230 hp / 605 torque.

That's a 37. 5% increase over stock values.



It's also below the torque where most toast the stock clutch!

Piers is only being responsible in notifying you that if you use a plate which produces more than the 230/605 figures, which are the limit of what the EPA has certified our engines for use in this country, you will be violating U. S. federal law when you drive the truck.



jgeen,

You're gonna' get a surprise one day. They may not do emmission testing but no vehicle is exempt from CA clean air act regulation. You're in the L. A Air Quality Management District? I don't remember where Valencia is, but even if you're not you can be ticketed as a gross emitter and they can make you clean up.



Nowadays people take a great pleasure in calling up with their cells to report heavy smokers. It happens all the time most places, and especially in California. One of the reasons I moved out of the state after 53 years there.

Not only can you get a ticket, but it's interesting to note that the UK cracked down on diesels years ago, because studies linked diesel particulates with damage to the lungs, particularly in children.



More recent studies on vehicle emissions are showing a linkage to respiratory problems in children too (e. g. BBC News Report , Houston TX Report). The problem with diesel soot, is that up to 85% of the particles are under 1 micron and easily abosrbed by a kid's lungs - they breathe quicker and are closer to the ground due to their height.



I'm not on a crusade, but just believe we can be the solution and not the cause of a problem, nor provide ammo for the lawmakers to legislate our diesels out of existence.

Damn, take it easy guys, you make it sound like I am blowing smoke like an old school freight train!! I don't have that much, it clears up after about 1600 rpms and only gets heavy on a hard bottom end launch. I could back off my AFC a bit to reduce that pre-boost fuel, but it's not that much. I can really control it with the go pedal.

I don't know about that smoke study and how it affects children. If that were the case then I think all diesels would be strictly emissions tested and there would be a 0 tolerance rule about diesels being heavy smokers. Diesel smoke can be just as harmful to adults as well as children, and cigarette smoking is just as bad for adults and the children who breathe the second hand, but we won't get into the details of that... ... There are way more diesels out there than just mine and most of those big rigs contribute to the majority of the smoke rather than just my little 5. 9L. Once that sulfur free diesel fuel is nation wide, diesel emissions will be cleaner than gasoline emissions... ...



Edit: I am not worried about it anyway, being I have a good friend up the street who is a CHP and he gets such a kick out of the power and smoke my truk makes. Plus he has already written off a few tickets for me and I doubt he would think twice about doing me that favor for a "gross emitter" ticket.

JGheen: nothing personal intended, a little smoke is understandable - just trying to make sure we'll still be allowed to extract the max power from our diesels without drawing unwanted attention from the lawmakers et al.

I heard they also want to increase the cetane level like the European diesel as well as lower the sulphur. Of course even cleaner diesel can be burnt inefficiently and smoke just as much ...

No offense intended here either, just expressing my opinion on that subject.

That is awesome about the cetane boost, maybe now we can get the same quality diesel that is used in Afgahnistan, which unbelieveably is where I heard the best quality diesel in the world is found.

Glad I didn't **** you off, too many people seem to take my comments too personally and throw them way out of proportion.

 

[britannic]

No point being too sensitive anyway, bulletin boards and emails don't always convey the necessary cues to determine the actual tone or intent of the writer.



In any case, I was always taught that to take offense too easily or quickly is a sign that one thinks more of themselves than they ought.



My chief passion is diesels and extracting power from them, so just about every dieselhead I meet becomes a friend if they're into the same thing.



I don't hold to any particular make or model, but of all of the diesels I've worked on in the US and abroad, the I6 Cummins is my favorite for strength, relative ease of working on, ability to easily extract more power and just that awesome distinctive sound!
