If you had 700 H/P NA at the flywheel what?
 
If you dynoed 700 Horse Power NA at the flywheel, what would that equate to at the wheels going through a 4400 Yank converter, turbo 350 tranny, steel drive shaft, Ford 9" with 430 gears and a spool, 28" tires.

Locked up ???

Not locked up ???

Just wondering.

thanks
tom

Damn, 700fwhp N/A only equates to 10's? <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

Well Tom if you did not have a Hot Tubbed car my guess,586HP at the wheels.

Do I get a prize?LOL.

A Prize? You bet buddy. How about a few passes in the new MONSTER. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> How would that be? <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> 2nd prize is one of those New York big buck drinks.

WooHoo,you bet buddy.I might even buy a round of those special drinks.

700 brake hp would make me giddy.Giddy-up.

John, looks like you figured around 17% loss through the drive train.

570ish at the wheels and easy 9's with any decent chassis.

Good lord Tom...is that what your new motor is putting out?

440 converter = 96% efficiency unlocked - loss of 4%

turbo 350 - auto, but a decent one. Loss of 10%

9" with 4.30s - loss of 3% with 9", 1% gears. Total 4%

steel driveshaft - maybe 1/2 % if even that

Total loss is 4+10+3+1+0.5 = 18.5%

0.815 * 700 = 570-571 RWHP

In reduced weight car, easy 9s.

You are really predicting 700 fwhp with LS1/LS6 style heads??

<strong>Tom,
Sorry if I've been under a rock, but would you mind outlining this new engine? Those are impressive power levels for N/A and I'm still on the fence as to how I want to proceed (N/A or FI). Would love to see what you're doing to get 700fwhp.

Thanks!</strong></font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">The engine is all speculation at this point. I have no real specs at this time other than it will be a re-sleeved LS1 aluminum block.

The bore at this point is undecided. The crank is undecided. The cam will be BIG but no specs yet other than it will be a solid roller.

The final HP lies upon my decision on what compression ratio to go with.

I still have an LS6 intake. To achieve this power level I may need a sheet metal intake. Can't afford one of those right now.

I'm not saying it will be 700 FWHP right out of the shoot. It will take a little more $$$$ mods to achieve it. If it is possible at all. We will see. We are just talking right now. The engine should be started soon and that depends on how I decide to proceed.

That's all I can say right now other than the rotating assembly will be strictly N/A.

When the time comes I will post more info but I truely don't know right now.

Tom

Sounds good Tom! Right now I'm having fun driving around the 396 with the little 229 cam, but I'd like to throw a 250-duration size solid roller in there soon. Why don't you do a 4.125" bore, 4" stroke, 13.5:1 cr, LS6 heads, and 250ish duration solid roller setup? I bet you should get 520rwhp with your lou'se goosey tranny. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
