cam chang benefits

Greg, you told me those 250 blanks were chinese with a fraudulent Brazil on them. Is that the ones your selling? Engine Power Comp. right?

It would be great for everybody to do a heads up comparrison in an unbiased testing facility. The general public would really be the winners. Don it has been quiet lately without you slamming me with false data and and general B.S.
Should I ask you again if you would like to go head to head? .......... Chad Westfall is wanting to get a story together for one of the diesel Mags. How about it? Would you like to have Lunch and talk about it. I'll buy

DDDAAAMNNNN!!!!!!!! talk about callin a mother f..... out. LOL

Hey zach, looks like no bite yet. JUST done turn this thread into a pissin match. But look like don has been schooled a time or two before. LOL.

All i am saying is yall both have awesome products and may the best triumph over all.

I'll volunteer my time and truck-- been meaning to get a cam anyway. I'll ask Reb if he and his dyno are up for it, and set some time aside if you guys are serious.
 
I will volunteer to do a cam swap I havent done my and I am still bone stock. I would like to see you as the best cam on the market right know.
 
I will say this, highest HP in a CR with single and NOS had a stock cam, and highest HP CR on diesel was F-1 H-2. Tow things on the dyno need to be checked, peak HP and power gained or lost under the curve. This is Very important and must be checked, this will show driveablity and How the power comes on.
 
Okay this is starting to get me going. I've been quiet about cams for a long time and let me tell you what WE have learned here. (I'm sure there is somebody else that know's more and has done more, yaddda, yaddda)

Question that opened this thread was "What do cams do (benefit) and who's to buy? In my opinion the cam is one of the last parts you buy for your engine. Peak power doesn't change much, but power under the curve (ie. torque, driveabilty) does go up. The over lap and timing is better suited for HP and TQ and NOT emmisions. I'm sure F-1, Max spool, and Ham's smaller cam will do all of these on a 300-700 HP engine.

The only time i would put a huge cam in would be a 6000 rpm engine with huge chargers, then more Lift will benefit "the cause".

Power under the curve is very important, this is why a year ago, a bullydog would make more peak HP on the dyno and a smarty would be half a second faster in the quarter mile. Smarty had more power under the curve. After tuning sessions with Marco, we were over 200 HP over the bullydog under the curve, and then we got the peak power up and over the Bullydog after.

The problem i have with max and ham cam's is that there is too much gasser thoughts going into the cam process. It's not a Gasser, its a 3500 RPM DIESEL!!!!!!!!. 3500 RPM. Cams don't do much at 3500 rpm, but a well built 3500 rpm cam wil give you TQ and power under the curve, and thats what most of them do.

Comparing these cams would be cool, i always love to see how different things work in comparison. It would have to be Same dyno, same mods and graph all 3 dynos and look at the curves, this will tell you everything. Seat of the pants will tell you Nothing and bias starts to kick in, the Dyno Jet 248 is unbias.
 
Let me put it like this. I just got back from my 3rd tour in Iraq as a tank gunner. I try to buy the best for my truck. If it's made in Texas I'll buy it here. At the very least I buy American (when possible). Everyone know's all these cam blanks come from Brazil. Sure there's a few Chinese fence posts floating around. But Bullet said they weren't worth grinding and that's all the further that junk ever went. Well, after I did the research I only had 3 American ground choices.

Bill Fletcher at Diesel Pros
Don M at F1 Diesel
Greg Hogue at Maxspool Engineering

I went with Maxspool because he was the only person I could speak to directly. The only man that picked up the phone from a soldier in Iraq.
 
Mine is a 12v but I put a h2 in this winter and it took me a few weeks to notice all the differences and one was spool up is quicker from a stop and when up and running down the road, EGT are lower for sure, gas mileage up alittle, pulls though the lock up at all speeds better, and I noticed on mine that mine revs up the r's quicker and maintains a higher rpm when gunned.

Zach, thats an odd statement to make. First off - its a well known fact you two don't like each other. Why would he call you and tell you he has chinese blanks just so you could turn around and bash him for it. I have run alot of different cams from different mfgs. I can not say anything about your cam though - never run one. After a statement like that, I doubt I will.


Dyno time is important, but real world performance often does not follow the dyno curve. A dyno run that looks like it will perform may not be the hot setup. A dyno does not load the engine like real world results. You do not have as much boost, heat soak is not a problem plus you can not duplicate the effect of air across the front of the engine. Trucks that make the big numbers on the rollers are often the ones getting beat on the track.

No disrespect meant, Reb. You guys build some awesome trucks. Just giving my 2 cents.
 
Why dont the cam people stick to making a great product and focus on making it better vs bull****ting , pissing and whinning on line. Answer the questions directlly asked answer the phones in a buisness manner and move on with more r&d.
 
The reason I made the statement is that I was looking at those cams. Greg said I was a fool to touch them because they were chinese. I think I am justified in having a little fun with catching him in a lie.


Brad, after all the B.S. and flat out lies that were started about my camshaft, I think it is ok to bring out facts and have the other manufacturers reply in a public forum. I do spend a lot of time improving my products, thankyou for your concern.

Zach
 
back to the thread... Twins will be in within the month. No boost leaks, timing is dead on, and the overhead is in check. Think im going with Source to feed the air. Cam pulls like a muthur in the mid range. Thanks for all the input Zack!

Reb,

will an aftermarket cam shift peak power higher in the RPM range?

It seems like stock cams make peak power around 3,000 rpms, but aftermarket cams peak closer to 3500.

Yes - without a doubt, BUT, it depends on the cam.
 
My Maxspool 2.5+ goes nuts from 2,200rpm to 3,700rpm with TNT-R high rpm setting. It's still a much more rev happy engine with all programing turned off. Pulls hard from 2,000 to 3,000rpm, where as before it would fall off around 2,500rpm.

Zach, that PRI show was 2 years ago. You want to bring up something recent? How about 5 months ago when you cut all your dealers throats on your springs??? Now back to your regularly scheduled program of cam change benefits.
 
Is power up or down? What injectors, turbo , head work, intercooler , and what smarty programming are you running?
First, check for the easy things. Boost leaks, valve lash, too much fuel for your setup etc....

These cams really move a lot more air than the factory cam will allow. On trucks with closely matched injectors, programming and turbos, you will see major improvements in driveability, power and egt reductions. However on some heavily fueled trucks I have seen major increases in EGT. Before you second guess your decision to buy one of my cams hear me out.

In a truck that is slightly overfueled, the added fuel will help clean up the excess fuel and lower the egts as well as make a few more ponies.

On a heavily overfueled truck there are a few things to consider. First after you have enough fuel to make heavy black smoke, you are effectively using all of the oxygen in the cylinder so any extra fuel you add has no oxygen to combust. What you see in this instance is that the extra fuel turns from droplets to a vapor. Anytime a liquid turns form a liquid state to a vapor it absorbs a lot of heat. It is almost acting like water injection to some extent. A lot of pullers and drag cars use this super rich state to keep their pistons alive.
Now introduce 20% more oxygen to the equation. That fuel that was busy absorbing heat is now producing LARGE amounts of heat thanks to the added combustion.

In short if your power is down and temps are up, something is wrong. Look at cam timing, boost leaks, and valve lash.
If your power is up and temps are up then Congratulations on the added combustion! You were and are heavily over fueled. Get some larger chargers and some head work!

Your power is from Smarty TNT-R not the cam. Lets be realistic, you make it sound like its a whole other truck, didn't you say you had a stock turbo, there's no power there with stock turbo, and definately nothing top end.

Moving the power range is done more with turbo and fuel tuning. Take a 12v, falls off @ 2250, throw in springs and holds flat til 3-4K. You take two trucks, same air, same cam, one is a 12v with 5K springs and a CR and the CR will fall off early and the 12v with peak and flat line forever. This is what I have seen, and when the fuelling to figured out top end, the CR should be the same way.

Cams don't hurt, the peak power doesn't fall off, it just doesn't give alot. The biggest improvement is on 04.5-09 trucks with the cam retarted so far, I thought like 9 degrees, not sure though. This is the biggest reason most don't regring CR cams because it takes too much metal off to get the timing right.
 
It was a COMPLETELY DIFFERENT truck on the stock turbo after installing the cam. I pulled a 32' racing trailer to Goliad, TX with it on stock tuning and the only reason I didn't mind it was because the truck wanted to use the rpm range instead of peaking at 2,500rpm. I'm talking 35psi on Texas grades of 1 to 2% here with no tuning at all. I had to turn my Dr. Performance variable gain off 30 miles from home because it threw a High Rail Pressure code on STOCK tuning. You're right. I was running out of air on the big end but, at 3,000rpm, I still had useable power. Instead of reading between the lines, you should just know I'm black and white. To appreciate how big of a difference it made on a stock truck with good tuning you'd have had to drive it. Since you haven't, I'd say your argument isn't credible. What's the deal, anyone that agree's with Greg is a liar? Greg's been nothing but honest with me and has treated me with the utmost respect from day one and I'll stand up for him and his product just the same.

And yes, it's a whole new world with the Silver Bullet. Yes, I have to rev higher now with the SB, but there's no doubt in my mind that the only reason I can daily drive my SB with TNT-R pod at 62 is because of the cam.

Here's my SB, good tuning, and cam on STOCK FUEL> http://www.youtube.com/watch?v=ezIG...OMfxQm0/hqdefault.jpg&feature=player_embedded
