im not sure how many have done any at all..even if you just did a (clean up) on it show me some pics.

We've discussed the porting on my car's head previously & it is more suitable for turbo than NA so don't do this. Minimal bowl work & intake / exhaust ports opened up so flows well on a flow bench but has probably lost velocity in the intake as a result.

Concentrate on the bowl work & leave the intake ports alone is what I've been told by a couple of very reputable sources.

Ow ok! I was getting this done in the next 2 weeks!

Any more convincing info clint? I was going to port the head and get the valve seats cleaned up! I may just get the stock VE manifold ported a little bit.

How good are the VE heads concerning roughness from the blueprint?

If i dont port the head it will save me $800

It's such a shame to see my old engine used as a 'not-what-to-do' reference!:(
In fact it's down-right EMBARASSING, such good intentions, and SOO much $$ spent to end up as a 'don't-try-this-at-home' section.:squint:

I'm not having a dig at you Clint, just further venting my frustration; and watching my bank balance SLOOOOOWLY recover.

On the flip side MAAAAAAAAAAAAAYBE with enough tuning THAT head could do the business?

I guess we'll only know if someone is willing to try...

Maybe after a stroker kit! that should pick the velocity up somewhat! :D

yea... not that i would really know, but maybe the porting would be usefully on a larger displacement engine. like a stroked sr23ve or somthing....

more compression, on top of ported head with cams that dont even exist yet...


i dont believe that porting your head was useless.. more room for improvement.

im going turbo any other points to look at

Here is what I've been told:

99% of 2L NA engines don't need more than a 2.5" exhaust yet our VE makes the best power on a 3" with a 4 into 1 header & decent collector... why?

It's because the intake velocity sucks, which is why the N1 intake makes no difference... the VE literally needs the exhaust (collector) to create velocity by sucking the air through the head. Concentrate on the bowls & valves & don't open up the intake ports at all or you will create flow but it will bog in the intake due to lack of velocity.

This all goes out the window for turbo of course, which is why my VE head would rock on a turbo setup.

Not to sound like a negative person, but I think the information that you stated is false. A ported intake manifold has been proven to make significantly more hp than a stock one, but based on what your implying it shouldn't.

I'm not going to get into if the VE head makes more hp ported or not, because it will make more power. But people need to realize where they are porting and why... thats all i'll say on this topic.

By the way, anyone who's ever took a ve head apart knows where the majority of the porting need to be done (just look at the casting flaws).

Hmmm

Well seems like I will see the results of a ported head combined with SR16 pistons with deeper valve relieves and N1 cams .......

Boring....:o

Before you shoot down what Clint said too much... Is 200hp out of an SR16VE unreasonable? I'll just leave it at that I think.

Do you know what intake velocity is??

Sure the head can flow 200+WHP but when you are not flowing 200+WHP, then the manifold loses air velocity through the ports as they are just too plain big for the low lobes. They just cannot create enough manifold vacuum as the ports flow too much air and when that air is not required, it loses air flow speed and that can cause fuel to un-atomise and dribble into the cylinder through the valves :(

Casting flaws cause enough turbulence to atomise the fuel well and yet the port diameter is enough to flow reasonable amounts of N/A air... essentially, area under the curve suffers with a N/A setup at the expense of having the most peak power.

Interesting.

Your post is irrelevantly to what I typed. I do not plan on talking too much on this subject because of people like you who have their 2 cents to add with little real world information to back it up.

I have a ported head on a built motor that is making over 200whp, with pictures to back it up. Until you can prove the same real world knowledge, please do not quote me with your internet read information.:redface:
