I will ATTEMPT to explain this for the slow people (Mikey) aka Stewie.
Lets use engine dyno numbers for this example since those are real numbers.
(1) 370 cubic inch motor makes 500 na with stock heads.
(2) Same motor makes 750 with 7lbs of boost
(3) Add some heads ported by Nix (had to Brandon) to the NA combo and it adds 80 at the crank for a total of 580
(4) Same amount of boost will now make 820.
Now, please explain to me how heads dont make as big of a difference on a boosted motor please.

He said he has a motor tune in it..so I’ll go out on a limb and say he needed his shop to show up to load the nitrous tune…
I “thought” the benefits of running a dry shot were you could keep the timing of a n/a tune till you sprayed and then it would retard the timing once the PCM sees the IAT drop…
I could be wrong…

Mikey/Stewie/Wizeass or whatever, he is basically right. Cylinder heads, more specifically the ports, are much less crucial on a turbocharged engine than an N/A or N2O engine. I won't bother to explain this, because it seems to me that this thread has attracted more **** talkers than anything else, but I will say that Katech has echoed this same conclusion at their seminar at the last PRI show.

Is this a real example, or are you just MSU?

Heck... they need to speak with engine builders like Erik Koenig and folks like Rick at Synergy... heck even the guys at RPM can explain it to em.
BTW, I am running a plate kit on a carb intake with a closed loop tune. I have to have the nitrous tune to spray the car. No standalone or maf in my setup. It does have a maf but it is before the nitrous.

Sounds like you should have went Forced Induction that way you won't have to wait on anyone to race your car. Mikey go buy a copy of HP tuners have the shop load the Nitrous and NA tune files on your laptop that way you don't have to wait for anyone. just switch the tunes your self. Makes sense to me.

Mikey is saying, and has been saying for awhile that stock heads are just as good for boost as anything. As usual this is just dumb.

Takes 2 mins to change between tunes for different sized shots as well.

MSU? You might be closer if you said MTI. Now you are talking about port shape and velocity. You are very correct that cross section and flow for an NA combo are completely irrelevant when talking about boosted combos. A head for a NA combo will loose a lot of flow numbers when shaping the port for boost. Pressurize the air on the bench and see how it picks up.

stock heads suck no matter what. They just are not as important when you start putting PSI in them. I was referring only to the percentage gain. When you put heads on an NA motor the % gain from the heads is much greater. Same thing with nitrous... add the bottle and the % gain is not the same as NA.... especially when you now have the luxury of upping the boost or increasing the shot. A motor guy has none of those options.
My point was stop using it as an excuse.
