Well I did some # crunchin this Morning with the flow stack...and here's what "I" came up with..

I only did 1 with the CompCam Specialty Cam...with the cam Installed on a 106* Int. 114* Exh.

510hp @ 6000rpm
482lbs..TQ @ 5000rpm
375lbs..TQ @2000rpm

So its Makin good Hp Now and Good TQ up in the rpm range thru-out!!

I hope I didnt miss anything?? It was to early this morning even to see the Keyboard!! LOL...

That was done on the DD2...I havent tried yet to run it on the EA3.2 too see what the Difference's are...But I will sometime today,and let you guys know (the one's that are interested ?)

Russ

 

russ, i would like to see a comparison with ea. I am interested why the dynosim makes more power than dd2000.

 

Well Matt , I still havent gotten around to doing it yet...I was out Putting in somemore stuff in the Vegi garden...And Defrosting a 1lb Ribeye!!

The wife and kid and Grandkid, all went out and its just me and my Buddies...(Dogs) Juke Box is a Crankin..and good times a rollin!! I'am going out in a bit and Polish the Turbine's on the truck... (wheels thats is) lol..and get them ready for sale!!

And to answer you Question..the EA3.2 Take's in a whole lot more infomation on an engine!! Bore-stroke-Rod Length-small or large bearing surface's-Case pressure..windage-Piston skirt Length..Stock rocker's- improved rocker's-Roller Rocker's-Exact size of the Header's..Primary Diameter-Collector Dia. Primary Tube length-Collector Length..Head port Dia- Head port Length-Runner length-from The Plenum to the Valve.. lol...

That just for starter's...I think you get the Idea now?? lol..

Russ

 

Hrm, I thought the consensus was that DD2k was optimistic with it's numbers. Maybe not?

 

No Kurt, I think if you check some of my Past post's...you will see where I have said...Depending on the HP range it uasually come's in about 6 to 8hp from my EA3.... Depending??

But this program gets right down to the Nats ***......lol...but it take's awhile to log in all the info..if your jumping from build to build!!

It was a $700+ program..a couple years ago...

alot of Engine Builder's use it..they just dont claim they Do!!! lol..

Russ

 

So Kurt!! what did you come up with on the Flow stack?? that I posted??

Russ

 

Well I ran everything thru the EA3 this morning..And came up with..

523hp @6000rpm
481lbs of tq..@ 5000rpm
270lbs of tq. @ 2000rpm

And all over 400lbs of tq from 3000rpm on up...

Russ

 

Ok here we go: Your flow numbers, 10.25:1 compression, single plane intake, 870cfm carb, large tube headers and mufflers, your custom Comp cam. Came up with:

493hp @ 6000rpm, 478ft-lbs @ 4500rpm, 366ft-lbs @ 2000rpm.

 

OK Kurt, I got 498hp @ 6000rpm and 482lbs of tq. @ 4500rpm and 381lbs of tq. @ 2000rpm Open Header's tho.. On the DD2..

Looks Like some Fun!!!

I ran some Crower Cams..and didnt like the Tq... Curve at all..But they made some HP @ 6500rpm...LOL..

Thanks for Verifiying!!

Russ

 

Run it with the Crane 343941. You get almost the same hp, but a better (IMHO) torque curve.

 

Well Kurt, I still ibetween walk and dont walk, on the Cam.. there are a couple that will clear 500hp by about 12 to 25hp..but then again thats giving up some low end..

I guess I want to much.. .I want a nice lopy Idle also...Just to put some Fear in those New Dodge's....My Neighbor's for one !!

And gas Mileage is the least of my problems.. As the truck is not a Daily driver..But I want to keep it depenable enough to be, if ever needed...

Well I have a few more Sims to run....I am documenting all my Finds on the different cams...

We will see....Thanks for you Help with Verifiying the #s I came up with....

Russ

 

RapidRuss,

Have you tried playing with lobe separation numbers on any of those cams you have been running sims on?

You can get a custom ground cam with just the lobe separation changed for almost the same $'s as the pre ground one.

Tmod

 

No Tmod, I havent made it that far yet?? LOL...I am just getting pulled to many different ways, than to just get to set at the Sim, and play!! lol..

I'll spend some more time on it? when the wife goes back too work!! lol..

Russ

 

Isn't the Crane 941 cam's idle smooth?

 

It depends on how you have the advance rigged. With the vacuum advance plugged into full manifold vacuum like I have, it idles good. 15-17" vacuum hot idle. With the vacuum advance plugged into ported vacuum, it's about 9" and sounds choppy and agressive. In both cases I'm running 6*BTDC initial. The vacuum advance pulls a lot of timing at idle when plugged into full manifold vacuum, enabling good idle with a big cam. The sound is still noticable though.
