Paging Wizeass
what concept is he not grasping?
if a head has to move air on its own it needs to be as efficient as possible...everyone knows that...on a N/A motor the better the heads the more power you can make.
if it has a hairdryer ramming it down its throat it doesn't matter how big the ports are the air is going in it....end of discussion...all you have to do to get more power out of a turbo car is turn the boost up....you can have the shittiest heads ever on a turbo car and still make as much power as a N/A car with good heads...
and like Mike said, better heads on either setup will make a difference...but he's saying a N/A motor with **** heads will lose more than a turbo car with those same heads...make sense??
The turbo makes up for the heads being inefficient.

you can only cram so much air down a narrow intake runner...you can only get so much air out through an unported exhaust chamber. so the answer is YES ported heads do make a difference on a turbo application. is it as critical as a n/a setup? no, but yes it makes a differernce.
let me see someone cram 5lbs of **** down a coffee stirring straw....now let me see someone cram 5lbs of **** down a paper towel roll....
i understand a n/a setup is more reliant on a good set of heads, but we're talking about FI and stock heads.

This thread hurts my head. Lol.
Somebody needs to go back to the basics of turbo cars. Why do all the 4-bangers put huge intake manifolds, and wild port jobs on their turbo setups???

Because it makes more power, is more efficient, lowers EGTs, etc. But I bet you knew that already.

answer this question If you have 10 psi boost on stock heads, what would your boost be with ported and polished heads set up for the blower? Should the boost drop or go up in pressure????? What would happen to the HP output???

they bitch at me about excuses yet produce the same ****. I just called em on it.
Blowers have a different dynamic than turbos. Turbos are based on air flow, and density. So if you have a larger runner that flows more they spin faster and quicker. It does have to translate to an exhaust port that is efficient and can keep up with the increase of used A/F. Otherwise you just increase EGTs, for a slight HP gain. Blowers are a fixed output based on RPM, but it still equates to some type of bottleneck of the runners and combustion chamber. Again, with EGTs being the indicator. Low boost, low EGT, good HP makes a well setup car that will last. Same thing goes for an nitrous car. That **** has to get out the back out without being too hot and tearing **** up. There are several cars here local that put some sickass setups on the track and make a pass or two with catastrophic results. You guys know who you are. And they are because you can buy parts and know **** about setting up a engine and tune. Good luck running the time Mike.
who the **** compared anything to a N/A setup you ******* moron. jesus christ.
i said to Viciuos i'm limimted to about 800 HP or so due to STOCK heads. what dont you ******* get about that. its not a ******* excuse its a fact.
"I have stock heads"
sounded like an excuse to me.
The hypocracy around here is insane!
that is like me saying:
I have a **** converter
I have a 270cc intake port
I don't have tires
I have a baby cam
I have low bottle pressure
I am missing parts
blah blah blah...
I was only pointing out that you having stock heads on a forced induction car is a really dumb excuse to use on why your car is _____insert whatever here_______.
Just sayin.... you paged me.... not the other way around.
More flow/Better Velocity = More HP, PERIOD
Once again Mikey, stick to yes or no answer, do not elaborate anymore in front of people.
