Can someone run this through a Desktop Dyno?

[Killer_Mopar]

Can someone run this engine through a desktop dyno and give me the readout??

400 stroked to 451 CI
10.5:1 compression
Ported stock heads with 2.14/1.81 valves

Hydraulic Cam with .520"/.520" lift, 276°/276° advertise duration, 230°/230° Duration @ .05, and 110° lobe center

1.6 roller rockers
Headers
Torker intake
and an 850 Holley

If you need any more detail just ask. T

[pishta]

need seat to seat stats (event timing) from the cam card.

[Killer_Mopar]

Havnt purchased the cam yet so I don't have the cam card. The cam is an engle grind and their website doesnt list the timing. The reason I want the simulation is to see if I want the cam What sucks is that you cant even take an educated guess on that.

Try it with this other cam I thought about getting..... Its the "HEH 2328 BL" in this list

[rumblefish360]

OK, this is how I made it fit in. Also understand that a single plane intake has in the past proven about equal to a dual plane intake in the real world in most cases of a street build up and the 230*'s at .050 is a small cam that could be driven with everyday. The run gets listed as a dual plane.
Also on the heads, you asked for them to be listed as ported, but how far?
Pocket porting or fully ported. If you have flow rates, let me have them.
There listed here as "Wedge, pocket porting large valves.
The cams lobe centerline is 110. I made the intake centerline 106.
Also a carb is a carb to this basic program. CFM ratings apply, not brand.

Bore, 4.375 X stroke 3.75 450 cid exact
Heads 2.14 / 1.81 pocket porting large vaves/wedge
10.5 ratio
Induction is 850 cfm/dual plane
Exhaust, small tube header w/open exhaust.
(Think real effcient exhaust system.)
Cam/Hyd, Timing for 230* @ .050
9/41
49/1
w/ .544 lift

478 HP @ 5500
517 TQ @ 4000.....

With the Hughes cam pluged in @ 1.5 rocker ratio.
475 HP @ 5500
522 TQ @ 4000

w/1.6 rocker
478 HP @ 5500
524 TQ @ 4000

[Killer_Mopar]

Thanks rumblefish, I was thinking 500 HP and 500 Tq...guess Im a little low on the HP. The heads are between pocket port and fully ported. The exhaust will have electric cutouts, so I think it will be pretty efficient. Thanks again.

Where do you guys buy Desktop Dyno? I'm thinking of getting a copy, last I checked, I think it was 40$ from the local speed shop.

[BDS 871 Cuda]

Desktop dyno is a toy for the computer. Don't put to much stock into it.
Have fun with it, play a little, then let a pro shop with the right program
set you up the correct way.

If you still need Desktop Dyno, you can have mine. I stopped using it
after about 2 weeks. It was part of a gag gift from some work buddies.

[ewatts94ram]

Hey BDS if you're just going to give it away I'll take it in a heartbeat. I think it'd just be fun to mess around with different combinations and different motors.

Same kind of boat here. The program is OK for understanding how things work and what can occur with what changes. It assumes the best built engine and other things that are not asked for the dyno run.
I have had a few people say there computer run was close to there actual build dyno run.
I almost for got to say last time, and allmost allways did in the past.
Take this with a grain of salt.

Things like cylinder head flow and actual math on comp. ratio, etc.... will do this $40 program credit. But there in lies the key. $40 program. Not bad for what it is.
Fun. Helpful. Teaching and showing.

DST, read above. I think for $40, it's a fine thing. Summit or Jegs have it as well.

Here's something that maybe you could play with:

That'll be great! I'll use it to teach myself some things.

ewatts94ram: I'll burn ya a copy if ya want.

I bought DD at Supershops years ago for 79 bucks. Call me rich, but not anymore....Anyway, it was a DOS based program that took almost 5 seconds to run a 1000 RPM slice and it was on 2 different windows (computations on one and graph on the other) It was real primative but it was fun to plug in wild cam specs and see the TQ go down to 0 after 8000 RPM. Anyway, I got a copy of Dyno2000 and it is light years ahead of the 1.0, lots of new variables and you can even build a head from flow numbers off the internet. I plugged in a set of 906's stock from a flow test so they are "as cast". Remember that you are Dynoing a "blueprinted" motor as it takes all the stock measurements to heart, perfect bores, rockers that are the correct ratio, stated compression ratios, etc. I still think it is a real interesting program and you could use it as a too to determine if a cam change would get you in the performance ballpark that you wanted. I have given away the 1 diskette V1.0 for years to whoever asked as it is now considered "abandoned ware" and I dont feel Im hurting anyones pocketbook. I got my 2000 and 2003 from a buddy, look on Limewire or other P2P servers for it as it comes up every now and then. Ill put the 906 flow file link on my board in a minute.

You know, I have never seen it on my P2P software... Every 6 or so months I search for it but never a result.
I guess car guys don't like my type of P2P stuff...

[ewatts94ram]

Yeah man go ahead and burn me a copy if you would. Thanks man.

Eric

[pishta]

Here you go guys, dyno2000 for your entertainment...Its bigger than I thought but the server is pretty fast.
dyno2003 was huge so get it yourself,and it was only a demo ;-)
next...Stock 906 head here

dyno2000

Load up dyno and put the 906 flow file in the BB mopar head sub folder. I checked the 2003 folder for more heads but there are everyones except Mopar (1 Edelbrock head) as if they got black balled or something..Maybe they know we know better that to trust a program to get things cookin?

[Clead]

Cool! Thanks for the Dyno2000 link. Electronic Arts bastards stole mine when they cancelled MotorCityOnline. Many users demanded an offline patch just so we could access the Dyno2000 built into the game, but EA never even blinked. Bastards!

[Glen440]

That program is not too accurate.
606hp@7500 520tq@5000
Not bad for a mild little 400BB with a dual plane intake.

It has run 11.29@120.5 at 3615lbs, I'm guessing maybe 550hp at the most.
Online RWHP calculater says 493RWHP on that pass. I think that is too high also.

[pishta]

Mild? post your stats! Are we talkin Gross or Net HP? 60 HP could be parasitic loss.

[Glen440]

I have a .040 400, 383 crank, stock rods with arp bolts, KB240 pistons at zero deck, 10.2-1 comp, runs on 91, everything balanced, cnc ported E heads that flow 324@.600, custom grind comp solid flat tappet, .555/.565 246/250@.050, that is calculated with 1.6 rockers so its closer to .520/.530, RPM intake, 750 holley, 1 7/8 headers,3" X pipe into 3" race bullets into 2.5" dynomax super turbos with 2.5" tail pipes,4000 stall 9.5" converter, 4.10 gear with 26" tire.
Through full exhaust it went 11.37@117.5, just the 3" race bullets 11.29@120.5. I used open headers on the test as I don't see a straight through 3" muffler being restrictive.
The engine was built with my home ported 516 heads and went 11.71@115.3 but cracked both heads so I bought some decent ones.

This engine in my mind is a mild one. Its 1 step up from the 8-1 comp 400 I had in it before that ran mid 12's on 87.
The pics on my site were after a drove it home from the track with a 440 in it. Ran 11.9's then. I'll add pics from the track.

[pishta]

Glen440, I tried your combo , kinda assumed the cam and got a closer 470 hp/480 tq but that was with 326@ 600 flow Canfield BBC heads. Your heads are awesome at 324, worthy of some more cubes!

[rumblefish360]

Now how did you post that. I have the DTD program and don't know how to get that online.
It would be very helpful to know rather than type in the hi-lites.

[Glen440]

ok I have a copy of the dyno sheet. The original run was with 830 for the carb, it has a proform main body and that is what they are supposed to flow. This is with a 750. I used open headers as I figure a 3" straight through to be almost as good. The cam I cannot put in the exact specs, this one is just short on duration a little.

I figured out how to put the cam specs in, 609/520 switch to a single plane its 652/545 I was gonna try a single plane anyway, gonna be curious to see what gains i really get.

[BigBlockRanger]

Best thing to remember about computer programs is that if you put garbage in, you get garbage out. I like DD2003 and think it can be quite accurate, given you don't fudge the numbers. The exhaust section could be better. I have learned a TON about what engine changes do what to the HP/TQ curves by playing with it.

[Glen440]

I just played with the head flow#'s, they made that part real stupid. I put the .050-.500 #'s in and it gave the real high HP #"s. I just put the .100-.700#'s in and it got more realistic 544hp@6500 507TQ@4500 That is pretty much what we figure the engine makes. 530-550 range.

I jipped you on the exhaust valve size and probably a few other things. Do you trust is any more now?

How did we post? I did a print screen (alt+print screen) and paisted it into a paint program, then saved it as a jpg or a bmp after resizing it to 700X700, glens looked much slicker as I tried to shrink the file size using a black and white scheme as opposed to 256 or 16 color. You may be able to save the screenshot with software designed to do that but I used the hard way...

[toad490]

Could somebody run my setup for me? I'm too cheap [read broke] to buy one.

4.25 stroke 4.375 bore 511"
Indy heads 325 cfm @ .600 lift
12.5:1 compression
Single plane Indy manifold
1150 cfm carb
TTI stepped 2" to 2 1/8 headers
solid roller cam- Intake .761 lift, 328 duration, open 34 BTDC, close 74 ABDC
Exhaust .729 lift, 332 duration, open 76 BBDC, close 36 ATDC
I think the cams a little big, the specs are with 1.6 rockers. The guy I bought the heads from gave me this cam, its the one he used with the heads but he ran dual Rons alcohol injection. With 1.5 ratio rocker it would be .713 intake and .683, how would that compare? Thanks.
