What's your best guess???
O.K. guys and gals, I'm almost there as my motor is just about done. What's lacking? My oil pan. Canton has just about got it right (third time is a charm....I hope).
Anyway, with any luck this thing will be hitting the dyno Monday the 22nd. So, how much H.P. is this thing going to make? Read the scoop and then take your best guess! 417 c.i Windsor, SVO Yates heads: flowing 343/265 Compression 13.5:1 CAM: Solid roller- Duration:316int ,322exh. 278/282 at .50 Lift: Intake- 688 Exhaust- 672 Intake: SVO, ported Carb: Braswell Headers KOOK'S 2 1/4 with 4 inch collectors Rockers Jesel This will be done on an engine dyno so take a guess on the H.P. off of the motor alone. ------------------ SVO siamesed 351 stroked to 417ci,Yates heads, solid roller,Trans King glide and a little blue bottle of giggle gas. My Car |
613hp @ 6600rpm

with out giggle gas, I'd say about 450 or so. With gas around 600, give or take. The more the better though. Good luck and I hope it breaks the dyno!!
|
I'd be really suprised if the engine number wasn't well over 500 N/A. I'll guess 525hp N/A, I'm not sure what kind of N20 shot you're running, so I'll leave that blank.

I figured someone would ask that sooner or later!! How about a Mustang Works t-shirt to the closest guess without going over. Also, there will be NO nitrous pulls on the dyno.

One dollar, one dollar...oh sorry that was The Price is Right. I'm gonna go extreme here, I would say 660hp.

I'll say 575.

Given 13.5:1 comp, that size cam, and 417 cu. in. of big, bad, as$kickin' Ford Motor...I am going to guess 529 HP.

I think the numbers are way off my self. That motor is alot like the combo they run in Winston Cup cause he's running Robert Yates heads. So those motors crank out about 700-800 Hp plus they have some rules that he probably doesn't. He also has more cubes, so I'm guessing 725hp@7500. Good luck man!

Wheres my guess on there? 725@7500 or maybe 8000.

626

632
------------------ Clint MacAulay 88GT 347 150 NOS |
Well I think that cam you are using is aimed towards when the nitrous is on. So your engine will loose a little power running naturally aspirated. So I would have to guess about 670hp. Good luck with the engine. Hope it runs well!
|
Like 93CobraR said, that's close to Nascar setup. If they put out over 700hp w/ smaller 9:1 compression and you're at 13.5:1, ported SVO intake, w/ 417ci, you gotta be close, but on the Dyno and realistically speaking, I'm gonna say 635hp. (I can't see ANY way that it could be in the 400s. That's way too low.)

I agree with the nascar idea, that is why I guessed like I did (660). I was going to guess more, but I have a hunch it will be a little less, brand new motor, might be a little stiff. Maybe this will help the other guessers, even though I want that shirt also.

A hell of a lot more than my car! I say about 623. Light Em Up!!! http://www.mustangworks.com/interact...oard/smile.gif

Yeah, I am going to have to borrow my friends Internal Combustion Engines book and hook up the equations to figure this one out.
95mustanggt, yeah your right engineering does make you think of the technical side of things. I'm in my 3rd year going for a mechanical engineering degree and I always do stuff like that.

500hp is high? are you kidding? similar cube ls1s on PUMP GAS (11.2:1) are making 500+ rwhp.
my guess is 675hp. |
hehe a lot of these lower numbers could be made pretty easily with a 347 and not even close to the compression level he has.
btw Kevin-what kind of fuel will you be burning? |
705hp@7300 rpms. Plenty of breathing, lots of cubes, solid roller cam, 'nuff said.
|
OK I'll play, 630 hp!

Hey Kevin,
you get that beast on the dyno yet??

UPDATE UPDATE
The dyno session has been moved to January 29. Canton did not get the pan back in time http://www.mustangworks.com/interact...gboard/mad.gif So, hang in there a few more days everyone. As far as carb size, Braswell doesn't rate their carbs by cfm but by venturi size. If rated to cfm it would be around 900cfm or so. As far as fuel, dont know yet. At least a 106 octane. I will update the spreadsheet to see where we are at soon! ------------------ SVO siamesed 351 stroked to 417ci,Yates heads, solid roller,Trans King glide and a little blue bottle of giggle gas.

It has been started and warmed up and the final adjustments are being made. During warm-up got a torque reading of: 450lb @ 3200rpm This thing will probably peak (torque that is) at about 5200 rpm so so far this is looking pretty healthy. Weather permitting (i.e. no rain or 30 degree weather) we will dyno the motor Monday the 29th.
