once again you offer nothing to it...suprise? flame on!
k .... so is this
https://www.cobaltss.net/forums/forced-induction-50/what-20psi-does-plastic-intake-manifold-54808/
your almost right....not quite tho
It makes the compressed air go in faster...yes, not the total air molecules itself which is detonated. Saying it will go slower is like comparing you sucking on a straw and then with the same amount of pressure with a 3 inch pipe. Same air is coming in, just not at the same "velocity" and density. Why do people want 3' CAI? I know....why dont you hook up a 1' CAI and tell me why that fast air is making you lose hp?
keep it constructive

Yes, the supercharger can make a draw for air but to the point of utilizing and even being able to supply the supercharger that same velocity of airflow and a larger capacity with a 70 MM throttle body is not going to happen.
And also once again, you can only compress so much air and you can only draw in so much air when the valves open. Yes, you're creating 18 PSI of pressure in your manifold but how much of that pressurized air is being utilized, that's a different story.
Seriously, why don't you just do it and stop wasting our times. You come on a forum and ask a question, someone gives you a answer and you disagree like you know what you are talking about and you will argue your point left and right...just ******* do it. Who cares what we think cause evidentally you DON'T.
And thank you.
I don't understand this thread at all.
ROFL

He lacks a basic understanding airflow, boost, and power output. He's failing to realize that if you can pull 400hp worth of air through a 60mm hole with 0 pressure drop, then it simply isn't a restriction and enlarging that to a 1000000mm opening isn't going to flow any more air.
Restriction has to do with pressure drops. If there is not pressure drop across the TB, it isn't a restriction. End of story.

It's like these people so quick to trash their intake manifold for something "larger" when it's far from being a restriction.

You want restriction, perhaps you should be looking at the stock LSJ heads first. TB is a last thing to upgrade. Even a fully ported Stage 3 Ecotec head cannot flow faster then an stock EVO head. The head is pretty restrictive piece IMO, so is the crappy LSJ exhaust manifold design. The rest of the exhaust outflow the header so imagine that restriction..
All that larger TB will do is make the air dance around the inlet. Also, good luck tuning the extra coming in. The momment you put that TB on without it tuned it will throw it in limp mode because it cannot read all the extra air.

I agree the TB is the last thing that should be changed. I also agree that the head is restrictive BUT I will say it depends on the purpose of the vehicle as far as powerband and RPM band as well. Honda cylinder heads are known for being high in CFM flowing capabilities but they are also revving 8k and sometimes higher.
That means that we win...
WE WIN! WEEEE!

PSI is built for a reason, restriction occur with PSI. You cant say the engine doesnt have restrictions. The tb was only a question but when idiots come on here and mention HP and not CFM, Pressure and other things it just ticks me off. Cylinder Heads will need a port and polish I know, and I know the MAF from and oversized tb wont read correctly without a tune as well.
Bottlenecks I was talking about were with flowing more air through larger space. Not how much that space can hold via pressure, density, and heat.

All of our comments were mentioning towards your "70 MM Throttle Body" comment.
OH NOEZ! U LT DA S3KR3TZ OUT!1111111

Are MAF sucks. It's the most pickest sensor on any vehicle i've ever seen. Thats why since it's so sensative we constantly have to make changes to counter or adjust what it cannot compensate. Even throwing an intake on the car makes it wig the hell out.

No fabbing required, it bolts and plugs right in. Only need a new coupler for the intake. I put one on my car just to try it, it idled ok and responded fast as hell, but over about 20% throttle opening you got limp mode. Something for me to play with when I get HPT.

I apologize, I think I took it as you initially asking about TB changes.
