Okay for Devon, this has been a money pit, and well 1st week he had the car
he spent 1500 for paint, 2nd week the engine locked up, after I dropped a
used engine in it, another 1000 later, Okay update,cleared the check engine
light and problems so far solved!, trans shifts normal for the most now!
any damage I blame on Advance auto parts, one for reading the codes to him,
but telling him he couldn't clear any fault codes? I'm like Okay whatever.
I never heard of an OBDII scan tool that couldn't clear the light out. so
he drove it after the fact, anyways my friend Joel brought his scan tool
over, we cleared the codes, and like magic, the trans was back in order for
the most, and well now 2 days later light still out and driving good, so
some good signs
Cylinder Head 204 - Porting & Polishing
This is a first-generation 1992 1.6L Hyundai Elantra
small-combustion-chamber head. Thats what it is. It's a J1 Elantra
cylinder head. Good luck finding another one like it. (read more)...
In Cylinder Head 106 I talked about the mainstream porting theories as they
are discussed. We looked at a cylinder head that I have thousands of
dollars of professional work performed on, and a bone-stock
second-generation head that I didn't port.
In this video I just might do something you haven't seen done before. For
some, that may be uncomfortable. The port and polish job I perform here is
what I think will work best for my current build. This is not an extreme
killer port job. What will be different here is where port textures are
concerned, I will be following the advice of a reputable source that will
remain un-named. You're free to port yours differently than I do in this
video, and I give you that out, around the 20 minute marker.
The Hyundai is far from being an ultimate-performance build. It's a $400
box of scraps with nothing but time invested. It's perfect for this video.
My finished product WILL be an improvement over what I had. I don't yet
have access to a flow bench. I still have an achievement to un-lock. As
far as you should be concerned with the techniques I employ... without flow
numbers there is no evidence of what this will do, but we will gather lots
of info from dynp sessions and drag strip time slips. If I could test it on
a flow bench, I would.
There are MANY, and when I say many, I mean thousands of flame war
mongering pirates floating around on rough seas with a hair trigger cannon
finger itching to fire if you port a head any differently than what the
herd mentality says to do while porting a cylinder head. I cover the herd
mentality because it has merit. It's been tested. Tried and true. But I
don't follow it to the letter of the law. I'm definitely not here to
de-bunk it. I would port a cylinder head differently for each build based
on how that engine was used. There's an extremely valid reason why
relating to air speed. It's not the texture of a port that maximizes the
effect of fuel atomization, but the velocity of the air running through an
x or y sized valve. The driving factor in this is the piston speed. I'm
not going to give you the technical information, but will refer you to
information about the Lovell factor. There's a better description of this
in the links below, and even a calculator to help you find your engine's
Why the Lovell factor is important:
Lovell gas factor calculator:
Only people who have flow testing equipment know for sure what really works
and have the capability to produce a perfectly-matched port job for the
ultimate performance build. Those guys know the definition of ultimate,
and THEY are floating below the water Aegis-class submarines ready to blow
your comment up if you don't know what you're talking about. They don't
care if you're an armchair mechanic or a herd of pirates. I will say,
they're zoomed in pretty close on me right now, and I'm expecting to take a
few hits. My work will be tested based on Dyno and drag strip performance,
and the results will be posted here. Fortunately, those kinds of videos
are a WHOLE LOT EASIER TO MAKE!!!
"How To" Port polish an intake manifold
In this video I show you how to port polish an intake manifold. Remember to
wear your safety gear and take your time. The intake itself took roughly 2
hours to polish. Removal of the head is recommended before any grinding or
polishing to ensure none of the filings make it into the cylinder bore and
cause damage to the cylinder walls.

Support 3800 vendors. I dont work for any of these guys but without them a
lot of us wouldnt be able to mod. Our cars are not supported by the big
aftermarket companies so heres a quick plug for the 3 vendors left.
