Big Chief heads for big block Buick

Please pass me some popcorn!

 

Haha, love it! (And if you pass some of his "popcorn" around its gonna get real interesting in here!)

 

Off topic: Mike empty your mailbox! Thanks. Carry on. And pass the popcorn. BTW I have T/A Stage IIs w/ shaft rocker system. They work great!

 

you sure you weren't imaginarying it ? ou:

 

I started eating popcorn in December wondering if anyone new would like to comment on a published flow sheet, attached. Actually, it was pretty quick that once the questions started, the posts were deleted, and I had spent some time to really TRY to explain things kindly in layman's terms to get the message across. So no more popcorn.

This was a report based on the before and after flow results with the reshaping of a combustion chamber. I doesn't matter who, what type of cylinder head.

Can anyone else see the fundamental problem with adding up the numbers and making conclusions like this? Hint: pretty much the most basic macrophysics class attendees, and even those who didn't attend that class, get it and can see the problem. This is a simple oversight and mistake made in basic math, and I hoped my input would be welcome, and I was nice about the whole thing! But of course that discussion was deleted and nevertheless, I'm the bad guy.

Gary and Jordan, give me your thoughts on the sheet too, if you get a chance.

I've got no problem being seen as some bad guy. I'm not in competition with anyone, I'm not pushing myself as a head porter, engine builder, what have you. I have nothing to sell, unless I decide to dig out some more old Kenne Bell intake gaskets. I don't do any of those things for a living.

That won't stop me from being direct and abrasive when need be when I see crap math and physics. Would you?

How do u reshape a combustion chamber to get more flow, at a constant 28 inches of water columb? And how do you drive around at a constant 28 inches. I would think one would need to work on the port for more flow, not the chamber.

 

From an earlier post where only .1 et and 1 mile an hour was picked up in a quarter mile, could you feel that on the street. Street racing is illegal but do you race for a quarter mile on the street? I say save your money and spend it on things that you can feel in the seat of your pants! Where the heads that are being worked on will not be for the street, hugh gains will be made in performance.

 

Devon, Post and say what you want, everyone knows you will. You live off Google search buttons and your math might work when counting your fingers but really really blows big time when it comes to understanding air flow. Instead of shooting off your mouth about a topic you no NOTHING about try shutting your mouth, put down the key board and pick up some tools and learn.

It is just like the argument that was made saying that you don't show gains in flow #s, you use %'s instead and total air flow #s were also criticized on the same flow sheet. Absolutely wrong on both subjects, I posted many flow sheets showing the same Data displayed.

I posted Data you guys don't understand but it's easier to run off at the mouth then it is to wrap ones head around it try to understand how it works. Instead you guys think you are a experts on air flow and ran off at the mouth about something you knew 0% about or understood. Instead you guys ran me into the ground to the point that I deleted my posting off MY own thread and destroyed all the work that had been posted. I will say it one last time and make is as easy to understand as I can, a engine runs on air and fuel NOT %'s If posting flow #s is good enough for TA Performance, JW's head guy, AFR and every other head porter it is good enough for me. The total air is very important data that I guess flew over heads here.

Devon you are a huge jerk, plain and simple. You are lame and something is seriously missing in your life dude, if you want to run around destroying threads and screwing it up for others then so be it. This whole deal is a BIG joke and you are the one wearing the big floppy shoes and red nose, head BoBo you are! Get a life dude. If they want to let you run around here bullying in the name of stroking your HUGE EGO then they better expect people to call a spade a spade!

Lets just keep running people off V8buick , its become a huge topic on other web site's.

Had I not been run off my own thread you would have learned that. If your statement was true then why re shape the runner on the other side of the valve job? Why can the angles on the valve job kill or improve air flow? Anything you change 1 inch on either side of the valve job can make big changes in air flow.

 

Buick Day tomorrow at Lebanon Valley. Hope to see some of you guys there!

 

The port is under the valve, as well as the runner. Your right I didnt mention the runner. Your paper says the chamber, Are the gains from unshrouding the area nearest the valve.? Would angle milling the heads be another way to produce gains in flow of the combustion chamber?

 

Yes, unshrouding the valve, changing angles, sweeping that area with a cutter etc. You set the head on top of the block to scribe a line indicating the bore size right? You then sweep the area with a cutter that controls/changes the angles, blending etc from the valve job to the deck. Its all part of the combustion chamber.

 

What do you think made your numbers go negative on the top.

 

I made changes on one side of the valve job that effected the other side, my intent was to do things step by step to show how it all worked together until the BS got thick and deep. These heads when finished went 342cfm @.650 lift and dyno'd 648hp on 91 octane, NA. I was set to keep posting all the Data until this BS started.

 

was it ext affecting intake or the other way

 

Being im very close to purchasing stg II TE heads, im absorbing as much as possible. I have home ported 2 sets of big valve irons, my generator , and a stand up scooter, i see no need to do my lawn mower. I dont plan on getting carried away, just some blending in the right spots.

 

I see where you added up all the numbers at each lift point to get a total "value of improvement" problem is this isn't a valid way of comparing flow data nor does it relate to horsepower and engine performance. It's the same thing as an engine builder dynoing your engine and saying he picked up 85hp on your combination, when in reality he just added up all gains and each rpm point. I think the customer would be disappointed to say the least. From looking at your chart and not knowing anything about the test of the combo I would say you picked up some mid range and little to no top end power.

Is is this the head that picked up .1 in the quarter?

 

I like to thank you for actually showing the difference's in changes when something is done. Here is my problem with a lot of people on here, Air flow is a "fool's errand" IT's velocity, velocity, velocity, swirl, then Air flow. Keep up the good work. Gary

 

So, Regardless of what you are saying, Mike at TA is stupid for going forward and making a new Cylinder head? Really? Jim, I'm sorry if I come off sounding mean or what ever, I'm Sorry! But I do know that making a cylinder head does cost money but, It's like you making your own Torque convertor, please don't change over to billet piece's it will cost you to much, even though you might already have a C.N.C. machine there! Jim, Mike can do 90% of his own R&D if he would take the simple class and learn more then you can comprehend. I'm not being rude on that part either, it's the truth. If big name NASCAR, NHRA, Cylinder porters and many others come there to learn something they don't know maybe you should look in to it. I sure did and learned more then I did know. Mike is very smart and I have talked with him for several hours on the phone already, We have talked about what he has tried and what has failed, but there is this thing called hope and he is running after it, Thank God....
