Applied Flow Technology - Competition Cylinder Heads

[505197]

The fucking robot machined perfect cylinder head, one after another produced to exacting specs. Fuck them goddamn souless contraptions and their assembly line perfection. I paid my dues sittin for hours grinding away, blending, match porting for real, not to a damn gasket shape the hope it matches when bolted on. The porter/tuner was a rare bird, and I am one of the best. Now a machine turns out Picasos, oh the humanity of it all. I was asked if I wanted to sell my Souix grinder, FUCK NO!!

@505197.....

What does a soul have to do with each combustion chamber/port being identical ?

If you are a good as you say then submit your chamber/ports for testing by BRODIX or AFR.

[505197]

@5150jafo I was saying that somewhat tongue in cheek, but it does bother me some. Have you ever actually sat and turned out a pair of heads by hand? Or built your own flow bench when no one had one? I have, and it kinda irks me that now they can spit out one head after another. You can air flow test a running engine, did you know that? Measure the exhaust flow..or spin an entire engine with electric motor and test in real world conditions, mercedes did in the 30s with their 700hp 5,7 L.

I've done the same deal using a valve grinder...flip the stone upside down and open the pocket..any questions?

[Spencerian]

Nice Job. :)

The machines a newen they cost like 250,000 au dollars but its an utomated machine all computer controlled. the last and greatest valve seat machine

[Marvosa]

is it possible to mess up soo bad that the engine wont work after this i mean... if u try a different way ... if anyone knows what i mean..

[MoPar7055]

What? Mess up so the engine won't work lol. You might seriously disrupt flow but why wouldn't the still engine run?

[mikethecollector]

if you try porting and polishing a head your self, and you do it wrong, you can have spots of the head in the combustion chamber that get really hot and can crack, or if its shaped really messed up and you leave a divot or something in there you can have detonation and blow up the engine

[MoPar7055]

but why wouldn't the engine still run, you aren't going to see detonation at idle and cruise because of a small divot are you? Of course you might see preignition and detonation if you crank the boost up and go WOT but that's always a risk.

[mikethecollector]

whats the point in doing head work at all if your not going to go WOT? The engine will run, its just most likely not going to run very long lol

[MoPar7055]

All I said is the engine would still run, and it would wouldn't it? I think it's a stretch to say that a small divot is going to cause enough detonation to blow up the engine at WOT too, if somebody is doing this much work they're going to be monitoring knock and such.

[mikethecollector]

my engine blew up because of a small divot in the bottom of my head next to the spark plug.... so it does happen

9,400rpm's doesnt help either tho

[minivanin]

agreed, as soon as i saw the chamber, it looked just my 3.3 (201) Dodge V6 heads

[iadr]

Could someone confirm for me what head that is?

[wheelhorse701]

It appears to be a 201 c.i.d. Chrysler V-6 head. Not sure what liter that converts to though.

[zapwatt]

201 C.I.D. means 201 "cubic inches" (inches squared). There are 2.54 centimeters per inch. So a square centimeter is 2.54 times 2.54 times 2.54 (square, right?) 2.54x2.54x2.54=16.387 201 c.i.d. times 16.387 [201x16.387] = 3294cc (cubic centimeters) 3294cc = 3.3 liters.

302x16.387=4949cc~5.0 liters

you can do it in revers too:

1.8 liters=1800cc divided by 16.387 = 110 CID

2.7 liters=2700cc divided by 16.387 = 165 CID

5.7 liters=5700cc divided by 16.387 = 348(350)

[MoPar7055]

Just multiply by 61.05

[65ShelbyClone]

The numbers appear right, but you're getting squares and cubes mixed up. Cubic inches is inches³ or the inch x inch x inch measurement you described. Square inches is inches² and is a measurement of area, not volume.
