So what was the final torque number or is the first
line it? Give us a little low down of it. Nice
HP number on it

WOW that is some BIG #'s
Be prepared the doubters will be coming
I have a big camshaft in my 416 with CNC W5's and mine made peak HP at 6900 rpm and peak TQ at 5200 rpm
I thought my peaks would be in the neighborhood of yours with my camshaft. Something to think about forsure.
Is your engine classified info or do you plan on sharing with us. I would love to see all the deatils on the engine

Re: w5 dyno - 03/11/07 04:50 PM
how much did your motor make this is the frist we used this dyno but a stuska # are lower then superflow # from what i have seen stuska is what we dynoed it on the last time we dynoed this motor it was a 386 with w5 not ported by shady and less com it made 638 and we also have alot better pan on the motor now the real # are how fast it gose so we will see here is the old sheet

Re: w5 dyno - 03/11/07 05:02 PM
Mine made 670 at 6900 and 557 at 5200
Dyno #'s always gets everyone fired up.
My 416 is 11.3 to 1 cam is 278 and 284 at 50
indy intake and 1050 dom
went a best of 9.96 at 136.75 which is way faster than I thougt. This is on leafs and thru the exhaust. So its making some steam
When will this engine make it to the track and in what kinda car. Track results is where it counts but dynos are good for fix'n leaks and making adjstments

I did'nt realize you read/posted on moparts Alan.
Those heads are also angle milled to 16 degrees, and have what? a 42 CC chamber? Neat set of 5's, I did a true "round" exhaust port on them. Only set I have done like that. Here's couple pics of the heads, I ported them at least a year ago.

You certainly seem to have those puppies figured out...
if you could get them re-popped ..? that would be sweet..
then we could ditch the 360-1 /2's
i wish i had more money to spend.

7800 isn't even 500 over peak and it looks like it holds on pretty good on the sheet.
Crossing 800-1000 over peak might produce the best ET.

I just ported the heads & did the machining on the heads.... So I don't have alot of input on it.. ARC built it & it's owned by another guy in LI...
As far as I know it's never been back to track after licensing passes, but I hav'nt asked anyone about it, so that could be wrong. I think it went back to ARC's shop to get ladder barred? or More tire or something done in rear suspension..... I was told the race weight @ one time but I do not remember what it was, I want to say it is fairly light, under 3000 race weight, but again, that is going off of something I was told probably 2 years ago.... my memory is not THAT good. I know ARC is still popping around here a little as he just PM'd me the other day so maybe Alan will see this & chime in.
My opinion on orig question would be..... That thing has steel valves in it, & probably 8000-8100 would be about as high as I'd want to turn it.

As far as intakes: get RyanJ to port an indy W-2 to fit a W-5. It is much better than an M-1.

Best was 9.007 @ 146. Atco last fall. Sunday at Englishtown went 9.12 @ 144
The car runs great but still looking for that 8.99.
I think the cam might be a little off. It is 284/288 @ .650 lift. You think its too much duration? By the way, the indy manifold is hands down the best to use. Last year I switched it to an M-1 and lost 2 tenths.

i used the speed calculator on this site..taking 2750 pounds and the mph he gave is 651 ponies.
as a comparison, my old car at 3350 went 134.71, 639 ponies using the same calculator..i ran a 727 compared to this 904, so a good running motor no doubt, but typical of a w5 build power wise.

Barry, what does your Challenger weigh? (& for those who don't know or had'nt figured it out, it also has a W5 motor in it, W/ set of SDSS hand port 5's)
Your MPH is little low for the ET.
Yes I am not surpised the 4500 Converted ICH manifold I did for you is faster than an M1....Great looking E body
You guys got good little bunch of well running SB Mopars out there @ Englishtown these days....with those W5 cars & I know ARC has a couple good running W9's out there as well... Hopefully I can get Andy Bittle's new 439" ICH 360-1 motor done soon so he can join in the fun.

Ryan,
Car weighs 2700 with me in it. 60 ft. is 1.24. 1/8 mile mph is 117. The car never was big on mph. Still thinking about the cam. It is a Comp Cams part # 20-716-9. Engine made peak torque at 5200 and peak HP at 6400.

Cam specs say lsa is 108 and it is installed at 108. Does advancing the cam make more power or just move the power band higher?

Re: w5 dyno - 05/25/10 04:32 PM
Advancing the cam will actually move the power band lower because it's closing the intake valve sooner.
It may or may not make more power. Depends if the head flow chokes the engine at the higher RPM, or if the later intake valve closing overcomes it.
Hard to say...
But it must not be too far off, cause that combo fly's pretty good...

Are you sure its installed @ 108, for the power curve I would think its 4 to 6 degrees advanced, But your makin good power right in the easy up keep RPMs, not too much stress on parts below 7k, should be a easy engine for a lot of passes

OK, Got out the specs and dyno sheet:
torque: 575 @ 5200
HP: 680 @ 6800
Cam: 275/284 @ .050
Lift .658/.661
Head flow: 319 @ .600, 327 @ .650 intake
235 @ .600, 238 @ .650
Compression is 14:1
Springs are K Motion 950's
Peak HP @ 6800 on a 4" crank W5 motor is completely "normal"
Everything looks pretty good to me, probably bit more power in a different cam, but would need different springs as well.. probably not worth screwing with unless you need to see the 8's with it for some reason.

Re: w5 dyno - 05/25/10 06:33 PM
Only one reason, so I can say I have a SDSS w5 headed small block that runs in the 8's.
If I was crazy enough to do it, what cam would you recommend?

How did you get the 14 to 1, domes or flat tops?
Posted By: barryc
Re: w5 dyno - 05/25/10 08:19 PM
Dome pistons. Dome height is .210, dome cc is 11.200

Thankx. good info any opinions on domes vs angle milling on W5s

That is a question for RyanJ. He knows more about small blocks and W5's than I'll ever know.

Ryan,
Why don't W5's use 11/32 valves instead of 3/8. Wouldn't the narrower guide and valve flow better.

Thankx. good info
W5's have a VERY thin deck so dome pistons are THE right choice. If they had thicker decks then angle milling would defintely add potential power.
I'm sure when Ryan does the W5's he replaces the guides with 11/32 or at least installs liners to drop the stem size down.
Lately we've been dropping stem sizes down on Indy stuff to .312 with good results. Lightens up the valve train a bit.

Thankx Brian, any rule of thum on cuting W5 decks, like .050 is max?

Uh...from what I've measured, as little as possible!
