not slow at all just stating the facts he gutted the ports and made them to dam big these heads respond better to bowl work and less gutting of the ports so yes whoever bolts this on has a high probability of loosing power

 

for a forced induction car this would be muchhh better than stock. an NA car would lose power thats it

 

a stock head would out perform this head boosted or not

 

why do companies offer port and polish jobs then? Why do v8's respond with a 20-30hp increase with pnp heads? How do u come up with your theory that extremely restrictive exhaust ports in a stock head outperform a pnp head?

 

from what i understand about the head the intake wasn't done much but the exhaust was.. i thnk it was gasket matched.. so it actually shoul be a pretty good head

 

and all you guys shitting on my thread can go get a ****** life

 

im not shitting on ur thread i am trying to help u lol

 

do you really think i was talking to you, or the guy hating on the PnP'd Head.... Think about it for a second

 

well pnp head is a good thing it will help but knowing what and were to remove metal is what makes the difference just hogging out a port will hurt port performance/velocity it dosent have to be huge and hogged to make a big difference look at the gmr head or the zzp or lsjion's (his head flows within a couple of cfm of the gmr head) they all have smaller ports and i bet you they will flow and work better not bashing everyone has to start some where and learn and having access to a flow bench will teach real quick what will work and what wont

 

its hard to tell on this site sometimes lol u will soon find that out...had a guy freak out on me cause i defended him once

 

looks like u did a good jobb and if the head is gasket matched then it should work out alright. glws bro

 

he didnt take out a ton though..i had mone professionally done cause i didnt feel like witting a water jacket or anything but he said he gasket matched and just took some away. The exhaust ports on this head blow dick stock though..thats where u will pick up gains on an FI car easily cause that air gets so trapped cause the ex saide is crazy restrictive. I was shocked to see how much smg took out of my ex side and how polished and smooth it was. Looks like the OP didnt do too bad of a job and an FI car looks like it would pick up a decent gain to me.

 

one thing people forget about ported head are, too big can hurt, velocity.
look at cars that go too big on exhuast set up, guess what, they lose power, you should match flow to power goals, you would need a very healthy motor to ever need to take advantage of this, on a sc car, it might not hurt up top, down low, it will hurt torque. ask me how i Know. on a turbo car you want velocty to keep the turbo happy. I won't get into all of it, but some people need to do research and learn before they smash a well educated person and in fact make themselves look dumb

 

I've flowed quite a few eco heads, and you can pick up over 20 cfm from just taking casting flash out, and guess what, it performs, much better than one I went more out on. Camshafts are also something you that can be too big, but people go as big as possible, because they dont know any better.

 

to the OP I'm not bashing you or your work at all, it looks decent for someone who doesnt do much porting ( I'm only assuming) porting takes a looong time to get good at.

 

way i look at it is any car on here that wants or need to port their head is gonna be flowing a lot more air than stock. Im pushing 400+ hp im sure i am getting better gains with a ported head as opposed to a stocker....thats the whole point i was making

 

a ported head WILL make more power, all that was said.....to my understanding was that it seems to be over ported, which WILL hurt performance, even a gutted out head with make more power sometimes, but a properly ported head could make more and take advantage of it, Again no disrespect to the work that was done.

btw I yeilded over 20 cfm of a slight port with bowl work, the size of the port isnt as important as people believe,

 

for the last time its gasket matched, it will be no larger or more flowing then the space in our Exhaust manifolds.

 

it's clear you have no idea what you are doing when it comes to porting and polishing. why not leave it to the big boys?

 

he is not the one the one that ported it .. ease up on the guy

 

whether or not he's the one that ported it, he's defending this :


and is comparing it to ZZP's. he has not a clue what he is doing. i have no intention on easing up on the guy

 

And your the ****** Loser who's writing in a thread that you have no interest in, I Thought the Mods on this site took care of trash like you.

Yes ive never PnP'd a head, but ive seen and ridden in cars that the guy( who ported the head) built up himself.

I trust his work, Sorry that this head seems to be fit more for Boosted applications than NA, But all that happened was he gasket matched the exhaust ports and knife edged the intake side, but didnt remove much.

Honestly GTFO of my thread

 

you really have no idea what you are doing, and if this is your friends head instead of yours, then your friend hasn't a clue either.

i posted in this thread because i am trying to save some poor sap the trouble of installing this head on his car and loosing horsepower, from douches like you that think they know what they are doing.

i've been around this car for a while man, i think i might have a clue by now

 

what is wrong with the head jesus of head porting

 

it looks like ****. the runners are not even, not even in the same intake port. the bowls look like ****. the "D" shape that they were apparently trying to make is upside down, among many other things

please don't assume i am a newb and don't have a clue

and please don't compare me to a religious figure that likely did not even exist
