also keep in mind that the dyno operator can add any notes he wants.the dyno i use prints out everything [egt,s-afr-oil pressure-water temp-oil temp-and whatever the dyno operator is instructed to add to the note section.

The power have 40 hrs and that's Hard hrs.
It's simple you don't have my combination of parts. I'll have Jim at Ozark Speed & Marine get you whatever you want on there. Keep trying different combos
this is the fourth generation of my Big Chief setup.
And 10.5to 1 is way to rich.
If you want to complain about Unbelievable power take a look at My own GTR's power on 93oct with 11.35to1 AFR's on 23 psi ,170 cid inline six it'll make you rethink what your doing. 712 hp 510 trq ..on the wheels so like 800hp on motor...and I'm running 26 psi on it now ZERO knock.

How much is your last dollar if it's enough I'll haul one to your dyno. lol I might have enough to buy the gas to get there but I'd have to win to make it back.

You can't say what any combustion chamber will do unless you've ran the same combo. Do you even have Big Chief heads on yours how about my one of a kind intercooler cores in the Lee housings?? I know my Diamond pistons are one of a kind they made them for me. I made the coolers it all makes a difference
My proof is setting in my shops and in in boats.

Just because it's Jim Darrs boat don't mean anything other than I've been in it with the throttles against the dash for 20 minute spans.

So as it stands your motor and my 598's are JUNK compared to this 170 cid rig from Japan sucks don't it??

looks like it is pro charged,completly different.

couple of things,first i don,t recall complaining,2nd the picture of the engines don,t look like big chief head valve covers,3rd 20 minutes at wot with 12-1 afr,sure.4,do you think you are the only guy with a custom 1 off piston?5,40 hrs on the big chiefs ,time for guides&valve job,maybe that,s why jimbo can,t seem to sell the boat.6 i have 500 bucks that say it will not make the same power on the dts dyno we use anytime you want to proove me wrong.7 if the coolers are not whipple or the ones dennis makes well no big deal.8 big chief heads on a pleasure boat,WHY when today,s conventional heads are so good?guess it,s more than a couple things,lol.

No I'm a Turbo man and a Precision Turbo dealer. That one is a 6766 cea but I have a 6466 on it now that the red line on the dyno graph. I've done and tuned a few centrifugal setups they hit to late to be any good on a boat but psi is psi.

And I'm a fan of PSI blowers.

I have FOAC's setting on my shelf. Yes there Big Chief heads no I run Titanium valves.

You don't know much about tuning any power I'd guess but yes it's ran many 20 minute full throttle runs. I just build better power then you it's not a big deal. There's a lot better builders than me I'm not on the net showing I know less then them why are you?
Heck even my MTI is making 1300+ on 93oct very common anymore. I think you know a few others that make over 1400 on 93 right go get'em lol I've heard 1600+ on 93

And my Racecar is my 598's as well no intercooler on 93. Soon to be the fastest 93 oct car in the world.

Looks like it's Procharged ........my goodness don't get out much do ya.

well id say you are pretty full of yourself but no problem,guess you and jimbo have a lot in common,you are both full of chit.carry on with your dream world big shot.anytime you want to prove me wrong bring it and your money.

by the way,the burn out in front of the bus co was very impressive,lol.

Clown you have more in common with Jim than I your the one talking without knowing what your speaking of. That's evident to all who read this. The more you post the dumber you look Sad but true.

I'm hearing the burnout looked good thanks. But it was just a brake check for fun I didn't think out in front of McDonalds where you might happen to work would be a good idea. LOL

Maybe you should bring your weak not tuned correctly power down to me. Pay me to tune it....just a thought. Because I'm sure your dyno guy lied to you had to to keep from hurting your feelings.

How's that for reality?? Or would you like to post more to look even more STUPID

Oh also if you knew the power that was all around that " Bus Lot " you'd realize again how utterly STUPID you are. People who are actually in the Powerboat world will know what I'm talking about.

Stop posting you cant win this one.
