no open cylinders wont creat power it will eat up your power you need back presure to help creat your low end power there is a ballance you have to have of back pressure and free flowing to mutch of one or there other will kill your power

 

Right so you agree? A properly sized exhaust system on an N/A car is essential.

 

I forgot about lag.

I've heard that about back pressure and low end before, but I really don't understand the mechanism there. It seems like any back pressure is just resistance against the cylinder moving up to expel the exhaust, so would rob power at any rpm.

 

DUDE,,IT WILL WORK LUST LIKE A COLD AIR,, PLUS IT LOOKS PIMPER. JUST GET IT , DONT BE SCARED. I THINK ITS SWEET.

 

A HAHAHHAHAHA, this coming from the guy who uses 2 commas and types in All Caps. ROFLMAO. I dont know if someone already mentioned this, but too big an intercooler on a small turbo, think front mount and using a 14b or t25 will cause too much of a pressure drop from turbo out to manifold in.

 

fist off cleantc i pray you are kidding and 2nd off dudehitt read this you need to learn about exhasut pulse and it also explains how restricion creats low end tourq if you need more info let me know i can give you some more links but this one lightly touches every aspect of the exhaust

dudehitt read this http://www.nsxprime.com/FAQ/Miscella...austtheory.htm

 

Wow... Bet Revilo has no idea what can of worms he was opening up here....

Cool it down a bit guys....

There is a lot of engine theory regarding exhaust....

A few tips...

Restriction on airflow into the engine is bad.... therefore no IC on NA cars...
Backpressure on exhaust is good, too much or too little gets bad results.

And... if you want to talk about IC sizes, please start a new thread in F/I, as those guys will educate you greatly.

 

Unless you are running pretty beefy power in your NA engine. You won't have enough to pull air through the intercooler for any beneficial gain in power anyway. If you don't have F/I don't bother with intercooling.

 

I think the reason I was told this is he meant the biggest intercoler you can fit on your car as in no matter how big you get it it will not be able to overcool your turbo, as for the exhaust NA cars you def need a right sized exhaust and sc cars I think too, the no exhaust is best exhaust only was meant for the turbo. Ive heard the no exhuast thing quite a lot from people that know their stuff so I am pretty sure thats true, however the intercooler I dont know as I have very little actually experience with f/i cars.

 

i knew this thread would come one day

 

 

This thread is ridiculous. Basically what Revilo is saying is, he wants to cool air coming from the outside with... air coming from the outside. Now think about that for a second... how smart does that make him sound?

 

this is getting ugly

 

Ok I get it...

N/A - - - better exhaust

Turbo and SC - - - intercooler

Thanks

 

No you don get it. Both Turbo and SC and Naturally Aspirated engines WILL benefit from a better exhaust. The turbo and SC is correct. How talking about exhausts came into the conversation when we were talking about intake is beyond me. Oh and:

No matter HOW "beefy" (lol) your engine is (naturally aspirated) you will never in God's name need an intercooler. LMAO, "Unless you are running beefy power". OMG Just DONT HIT THE REPLY BUTTON if you have no clue about the mechanics of the subject. PLEASE save yourself the embarrasment .

 

Eh your wrong buddy. When your car is NA running 13.1 compression ratio in a v8 short block you can run an intercooler. With that engine you would have the power to actually get the air through all the piping efficiently enough to get some cooler air into your engine. When you can buzz a large v8 at 8 grand you CAN run an intercooler for gains. I also stated unless you are running F/I don't bother with an intercooler. And the statement about running an intercooler with an NA engine was a general statement. It has and can be done.

 

I'm totally confused here. There seems to be some misrepresentation as to the function of an intercooler here. What function does an intercooler serve on a N/A setup....NONE! What does compression of the cylinders have anything to do with an intercooler? As stated above, you would be cooling outside air with outside air, how in the bloody hell would that work?

 

Compression ratio of your engine directly effects teh power of yoru engine. To run an intercooler in a N/A set up you need power to get the air through the piping and intercooler effective enough for an intercooler to actually do any good.

 

That would be like wetting water with water

 

intercooler? you can get an interfooler.


its just a thin sheet of metal to look like an intercooler lol.
