Looks good!

that's what yours would be like unless you decided to step up to CNC..but definitely not necessary

I'm getting great response from the AKRacing/Promaxx heads... I'm pleased with the results and confident that they are without a doubt a solid player in the marine performance industry!!!

All this sounds sooooo familiar.....:party-smiley-004: :helmet:

Yup, the every reply being an Advertisement is getting old. Not even low spoken hints that you sell them, but proclaimed with !!!!! to boot.

IMHO.

Surprised Griff or another mod isn't all over this.

sorry guys... Yes you are correct, I build them, and I suppose I've gotten a tad carried away... as would anyone finding a new product that is great to work with..

agreed... I will refrain, I'll only speak of what is asked of... :poopoo:

I will fill you in with finished flow numbers. The heads have a lot of potential without question.

your inbox is full

Promaxx 317s
 

So here ya'll go... first real dyno session with the new 317s

[ATTACH=CONFIG]564769[/ATTACH]

^^^Get the sheet with the fuel flow (lbs/hr) and post them up, Thanks ! Airflow would be nice too.^^^

I wish I could run a 108 cam, that's some nice results... did I miss head flow numbers?

way back

It's ok SB I wouldn't want anyone to think I'm advertising my heads now would I? :angry-smiley-038:

I will look..

these are the numbers with my bowl blend before I worked the exhaust ports...

AK Racing 317s Intake .200 = 161cfm, .300 = 234, .400 = 292, .500 = 348, .600 = 378, .700 = 391 .800 = 396 exh .200 = 119, .300 = 162, .400 = 209, .500 = 232, .600 = 261 (w pipe 283) .700 = 272, (288) .800 = 280 (293).+++

Not saying that.

That sheet does not have much info. I would hope the owner of the engine received more info than that. If he didn't, he didn't get much for his money, other than, well, a sheet.

not my dyno

SB, i never see you question a dyno sheets validity when it was a marine kinetics build. But foxwells name is on that sheet, so it must be bullchit.

Still havent seen a dyno sheet , posted from anything youve built or dynoed

numbers look to be in line to me for the parts and cam spec I see listed...a tad hairy for a marine engine but power seems right on for the parts...

The thousands of threads plugging afr heads on oso over the years were ok. A guy plugs some new heads hes been playing with, and its a crime.

Were those heads ported by Scott Foxwell? I see his name on the dyno sheet. He's a talented cylinder head guy so it's hard to know what we're looking at. Out of the box power, or worked over by him? Also, are you going to blend out that lip from sinking the cutter in so deep? I like the Promaxx heads, I've used a couple sets of the 320's, and like everyone else has said, the quality is very good. One set was supplied by the customer who had Jason set them up for a marine app for him. I don't know if they'll still do that, it was a couple years ago, but the clearances were right where they needed to be.

Alex, those heads had a 2.300 valve installed, and a valvejob/bowl blend from foxwell .

OMG.

I study all sheets. Don't you ? No matter who built or dyno'd ?

Of all people, I know you want things legitimized.

How can you call BS or give out a congrats when a sheet has no info to validate ?

Stop being such an azzhole.

You kick Bob in the nutz every opportunity you get but it an't okay when I did with Straub ? If you haven't noticed, I stopped a while ago.

You pimped MK for a time. In fact, look to see where I pushed him on someone in OSO.

Okay, so he's done some work. Has he posted the flow sheet on those ?

By an advertiser or ?

It's one thing being excited about something and talking about them, it's another when you turn into a billboard to make $$$$$.

Al knew what a few of us mentioned this, and he was cool. I understand enthusiasm.

idk,i kind of like information on a product that that is somewhat new on the market.scott,s dyno numbers look good but i would rather see some out of the box numbers.big al is offering these heads for sale to oso members,so what, is he hurting anybody on oso?i am not sure why sb has a problem with it,i guess that,s the internet.ya just can,t make everyone happy even if you are giving money away someone won,t like it.

I agree Mike. Whether its afr, dart, engine quest, promaxx, whatever. Its all free info.

i understand what you are saying but i don,t know of any paying advertiser,s selling the pro maxx heads.also,maybe i missed it but i did not see big al pricing them on the thread.not trying to start any arguement with anyone,just saying.

I agree in a way and don't agree in a way.

To be more clear, mentioning something that has worked out well for you and sharing it ith the other members is all good,

Read back to the billboard posts. Again, Al got it, not sure others have.

There's companies paying big bucks for advertising...sure no promax, but other heads....you wouldn't be mad if you where spending hundreds each month when others are making money without doing so ? Check out OSO's advertising rates...they are big $$$$. Without advertisers the forum wouldn't be around.

That's all...trying to be fare. Not trying to pick a fight on this.

Why dont you start, by being a paying member, if youre so concerned about supporting the forum

Will that keep you from attacking me ? And not just on this current subject ?

The pin has been pulled 3,2,1... :)

myself,and i am sure many others never heard of engine quest heads untill you posted about them.i bought a set and finally got around to dropping them off for a cnc valve job&assembly today.they are going on a 509 i am building and whenever i find time to get it done it will get run on the dyno and i will post results.if big al wants to send me a set of his 317s i will swap heads and do some pulls with them and post those results also.

did not see that coming,lol.:party-smiley-004:

ya big al is cutting a fat hog on these heads,he sold one set and is working on set number two.i don,t think he is putting any paying advertiser,s out of business,again just saying.

Not the point.

I said my peace earlier and quickly...you guys keep bringing it up. So it sounds like I'm going on and on about it. I'm not, I'm just answering you guys.

Okay so you guys did get me to look at member prices as I haven't looked in a bit, Gold $24.95 6 mos, Platinum Member is $45 a year, Commercial is $500yr, and being an Advertiser is more. I don't need the extra benefits given as a paid member, but if keeps MT off my case once or twice a month ????

So, back on track. Can we get the other dyno #'s and his flow #'s to see ho good this motor / those heads are ?

Same info I got with my dyno sheets, it`s all the info I need, No complaints here . I`m interested in the power numbers and change in power who gives a $hit about some dyno air flow ..

Big Al don`t let this ass discourage you from posting here again , closest he`ll ever get to a big block is youtube..thanx Buddy.
