First of all... What do 12V springs have to do with cams?



When possibe. When possible! As I stated earlier in this thread, I buy Americam WHEN POSSIBLE.

MY CAM WAS GROUND IN THE US PERIOD> Zach, can you say that? You can't say that your cam's are ground here in RED, WHITE, and BLUE. And yes, I was in Iraq. Calling during your distributing hours. Which, for you not in the know, is +16 hours. Sure, I didn't want to pull the card out. But, I did. That was my 3rd tour. Zach, how many tours do you have? How many friends have you lost, or scooped up off the ground? I'm combat arms, I do the real deal. What do you do for the U.S.? Other than send you cores out of our great country to get ground? If I can't get service then who can? It isn't a matter of wether I was drafted or not, it's a matter of I DID IT. And for your info, I loved it and re-uped on Christmas day in Iraq during my first tour and volunteered for my second.

You should first take pride in being an American. Then take pride in being a Texan. Instead, you have no pride at all. And you have the gall to blab about it on this forum. Way to go pal. A true American...

You all know how these threads are going to turn out... The only person that's ever going to post any actual info is Hogue.

Zach don't put yourself on a pedestal because you and Don shun him out of a shootout... Greg will put a cam in that "shootout" if I have to drive there, pull my own cam out on the spot, re-install it, and drive back to Ft. Hood, TX.

Wow, so are you saying that if someone isnt in the Armed services, we are bad Americans and dont do anything for the country? B/c Thats the way is coming off which is BS. Yes, thank you for what youve done and are doing, but those comments are out of line IMO.

And as far as Greg putting a cam in I believe he was offered already to put a cam in.
 
Zach, what kinda of testing you guys doing? You gonna do some real world testing as well or just drag race/dyno stuff. I want to try a new cam in my RV hauler/work truck. I might have one of your mild cams already from PDR was gonna try a helix 2, but ...

I don't know why Zach is getting singled out for where he does his work at. Go beat up on fords, dodge, GM or Cummins... start with the big guys, not the little mum/pops shops. Sorry, I like the info on camshaft more than the politics, we can beat this to death but as we still can have the best camshafts period for our trucks, I'll take it.
 
Mighty Goat- I asked greg if he wanted in and got no response. I did not shun greg.......greg did or his firefighting day job did. Whatever the case I asked him if he wanted in. He is a big boy, let him answer why he didn't come down and put a cam in the tests himself.


Sir as far as your service record, I commend you for the service to your country. Do we have that clear?

Can you just let it go?

Mike we did driving under all types of conditions. I have mileage before waiting on the after. We have boost and egt before and after. all I am waiting on now is the track times. I should have those within the week. Based on the dyno sheet, I believe mileage will be up and the track times as well based on the improved bottom end. But I will wait on Real data and not make any presumptions. If you have a cam from PDR, you do not have one of mine.

BTW mighty goat here is what was said on page 6

I can not WAIT untill someone spends the time to do some dyno testing between the diff cams out there.
THis would be much better than just always having big pissing matches.

Lance

Hey comp, I can do you one better. There is a magazine article being done about cam comparisons in the next week, you want in? I will even let you install your cam if you want to. 2006 cr with a s366. You down?

Wow Mighty Goat really loves Greg...Why don't ya let Greg fight for him self or did he ask you cause he's skeerd???? Hey where is Mr. Comp???

I tried to do some track testing this weekend but the mighty nv4500 let go about 60ft...

Back to cam change benefits.

Dude, you are the new CompD village idiot.
 
well lets get this kinda back on topic ive seen some guys run some custom cams on common rails they have a s366 which normally spools at 1800rpms on stock cam but now with the cam it spooled at 1400rpms one has a maxspool cam and other has a fletcher cam 400rpms sooner would be great as im looking at get a s465 and they spool at 2100 rpms so that would put me at 1700rpms but would a cam the increase the spooling by 400rpms also have side effects such as really high egts like 1800deg sled pulling as ive seen wouldnt this not be good on parts and engine for durabilty
 
KJP- early spool is a balancing act between a few factors. If maximum early spoolup is your only concern, you will be leaving some power on the table at high rpm due to negative side effects. A well thoughtout camshaft will have great spoolup and great power at high rpm, lower egt's and better fuel economy. As in most things there is always a trade off in engines and camshafts especially.
All too often, people that want great spoolup go for the big easy, open the exhaust earlier. Want it even sooner, open it even earlier. This is the easiest way to get the turbos lit up. For all out competition it is almost a win-win any way you look at it. But for a street truck there are many negative consequences that are not brought up.

The four stroke engine is just a big air pump. How well it pumps air is measured in VE or volumetric efficiency. The camshaft is more or less the ECM of the air pump. It programs how well the pump flows at X rpm. To simplify how it works think of the exhaust and the intake as two separate entities. Forget about spooling the turbo for a second. What does the exhaust lobe do then. Its main job is to expell the "waste" of the engine most efficiently. It needs to be able to get the exhaust out with as little pumping losses as possible(frictional losses due to exhaust restriction). Independant of the turbo, if you open it too soon then you are wasting a lot of the energy and torque potential. Energy in the form of still burning fuel that should be pushing down on the piston and in turn spinning project x's tires, is now trying to spool that oversized turbo. Because of this early release of still burning fuel, you have a nasty exhaust sound, higher egt's, lower fuel economy than you might otherwise have, higher drive pressures at higher rpm, and slightly faster spoolup than a well designed camshaft. All at the expense of efficiency. On a side note, because of all that extra exhaust flow, Now that larger 74mm turbine wheel that is supposed to help lower drive pressure at spoolups expense, is not adequate to control drive pressure. Now at high rpm it is necessary to have an external wastegate to expend all of that extra exhaust flow. The same flow(energy) that should pushing on the piston and spinning project x's tires is now completely wasted to atmosphere, when it should be pushing the truck to another 14second run.
 
Because of piston cooling jets, retarded timing, Lower compression ratios, lower rail pressure settings and EGR(6.7l) it takes the fuel charge longer to burn and it burns much cooler.
The faster the fuel-air charge burns the hotter the combustion temps. If these temps. excede 2500 degrees, I believe, oxides of nitrogen form(acid rain), there is more power, better fuel economy and increased spoolup. This is why a small pressure box does wonders for a cr. Due to all of these factors the fuel, on a stock truck, takes longer to burn. Now increase the timing, rail pressure, Injector size, turbo boost and the fuel is completely burned sooner.

Stock 12v exh profiles were typically around 204@.050" duration, 24v's were 206 degrees @.050" due to the slower burning fuels the Common Rails went to a very small 191@.050". This exh. profile made the turbo spool much slower. That is why a 9cm housing was needed, to get spool back to decent.This smaller and retarded exhaust was ONLY implemented to give the fuel longer to burn and to lower N0x emissions. On 2006 and later, rather than to retard the cam further. So that they did not have to redesign the cam the factory mandatd .026" lash as opposed to .020" on 2003-2005 trucks. If a truck has had any modifications at all then the fuel-air charge is done burning before the factory profile opens the exhaust valve. So a larger exh. profile is in order. So that we don't negate the engines efficiency we chose a 210@.050 exh. It spools the turbo better but it does not get in the way of the combustion process. The cool part is due to the 181/210 design. the lash can be set at .020" or .015" lash. Set at .020" it has lower egt's, better fuel economy and more torque efficiency. Set at .015 it will spool the charger sooner, have slightly higher EGT's, slightly less fuel economy, and make between 15-20 more HP. This all due to the SLIGHT increase in duration, and the fact that there are many other things dealing with ramp rates, lobe separation and intake placement that help the 181/210 to spool and make efficient power.

Stealing energy from your rear tires with larger exh profiles to spool your charger is the dumbest way to improve bottom end! On street trucks it should be reserved for people ignorant of all of the facts, or those that take calculated risks in the racing world. Definately not for a street truck! It can negate up to .750" of the piston stroke. You more or less are destroking your engine! I choose effective longer stroke, torque efficiency, lower egts, better fuel economy, smoother exhaust, and faster than 13 seconds at drag week!

Ok.....

This is Apples to Oranges, You can talk about your Combat Experiences, and then hate on a guy for doing what he can to make $$$ in a FREE MARKET Capitalist Economy

And last time i checked, you werent drafted, and you volunteered for ALL of your tours, because we serve in an ALL VOLUNTEER FORCE Stop Milking your service, it wasnt that bad, and if your so bitter, get the F*** out and stop making the rest of us who are serving look bad. I dont know how you guys do it in the Army, but here in the Marines, we have tact, and a little bit of respect for ourselves. Stop looking for an argument over the net.... S***'s Weak.
 
Mighty goat, I attacked your economic views. Not your service record! Your gettin it all mixed up man! Come down to Liberty Hill, TX let me buy you a beer. I'm not 30 min. from fort Hood. I always will make time for someone that has served. I DO respect that.

I tell you what, if I give you a genuine made in the USA set of springs, would that help bury the hatchet(K-bar, m-16, or RPG) so to speak?

I got an RPG Buried in my back yard... If he doesnt, I'll take you up on that Beer, I live in Round Rock, so that isnt that far from liberty hill.
 
Mighty goat, jason, heck any comp D members. 6:00-7:00p.m. at my shop Beers on me. What do you guys drink? If you have been in the military and you have a comp D screen name. free 24v springs! I Support our troops, but not necessarily their economic views, sexual orientation, taste in women, or who they voted for. Signal, you might be a little too far away to take advantage of the offer.

Agree to disagree?

Sir, I'd buy you a beer first. However, Minneapolis is a little bit of a hike to tx for beers :)
