CONTEST : Guess the HP and WIN!

-
To me, it will all depend on what the converter will let it do, and how good those tires are on the dyno.
Soooo, .... I will be very conservative and say 410 to the tires, BUT, if that thing is under 3000lbs, I'd predict very low tens.... or high nines.

Alright boys and girls. Time for a contest with a cool prize to the winner.

Heading to the chassis dyno (Dynojet 424XLC2 with 5% SAE correction) on Black Friday and whoever guesses closest HP to the tire will win a Swag Bag full of cool stuff. (Nitto Back Pack, Mopar Hat and custom A-Body t-shirt, BrawlerFab t-shirt and a Brawler Shot Glass. Free, shipping included!) The contest will run from now until about 4pm Pacific Standard Time this Friday which is about when we should be done on the dyno. I will post videos and pics at the conclusion of the contest.

Here's the combo to help:

Balanced 408 stroker with 12.5:1 CR running on Renegade 110 octane race gas
Out of the box Trick Flow Heads with titanium keepers
Out of the box Trick Flow Intake blueprinted on install to perfectly match up ports
Thumper 850 (flows 977) carb.
Comp Cams solid roller cam 660/660 and 258/264 @ .050 108 CL
Harland Sharp 1.5 ratio roller rockers
Hedman Hustler 1 7/8 race headers with 3.5" collectors
3" dual exhaust with mandrel bend x-pipe and Dynomax UltraFlow mufflers, with turndowns and no tailpipes.

MSD 7AL3 ignition with a MSD Billet distributor locked out at a conservative 36 degrees and a 7000 RPM pill.
NGK FR7 plugs gapped at .040

Built 727
PTC 5800 8" non-lockup converter (tight)

4" chromoly drive shaft

Fabricated 9" with 4.30 pro gears and spool and 40 spline axles (not that the axles matter other than they are heavier than say 31 spline....lol)

15x10 Billet Specialties forged wheels
295/55R15 MT Drag Radials.

What do you mean a 5% SAE correction factor?

Reading that, are you saying the dyno is in a temperature controlled room? Because the weather correction factor is based on the weather, not a fixed percentage. Unless of course the dyno is in a controlled room.

A 5% correction factor doesn’t make any sense outside of that (that I can think of).

It’s the correction standard as determined by the SAE (society of automotive engineers) and used by most dyno operators that want results that are inline with baseline standards. I didn’t add that info to confuse anyone. I added it because if I didn’t, then some would think I went for higher numbers by not using correction.

It’s ok to not understand it as I don’t fully understand it either. I just know that it is the industry standard used by most operators that want a more realistic number versus an inflated one.

That’s why I’m asking. Because the weather correction standard (no matter which SAE standard you use) is based on weather at the time you are on the dyno and it’s almost never constant.

I had one of my engines on a dyno a while back and I watched the correction factor change every couple of hours. It went as high as 12% that particular day.

So if that dyno operator is correcting to 5% all the time it’s ok as long as the weather doesn’t change, or the dyno room is climate controlled.

That much converter was my first thought on a chassis dyno when i first started reading this. I have to assume the tune is already spot on or all bets are off imo.

That said, i'll go 460hp and hope i didn't copy someone else...

Good luck Fri and don't break nothin' trying to hit a number. :thumbsup:

We will do some fine tuning on the dyno (weather hasn’t cooperated at all lately) before spinning it too hard.
 
I'll pm you my address because I know I'll be correct lol... probably the cheapest shipping too lol×'s 2
