No you dont get it. Who said anything about temp?? Exhuast deals with flow/velocity. Flow is the speed of air. You flow FASTER with a small straw. With a big straw you can flow MORE air but at a SLOWER rate.




No its not backprssure. Please tell me houw a free(er)-flowing exhuast causes back pressure. Thats like saying an air pump pushing air into the atomsphere has backpressure, no it doesnt. You cant measure pressure of the air flowing out.


You tune the exhuast as a WHOLE. So if you have restrive mid pipe,bends/dia. then it will effect how the exhuast gases are pulled out.

belive me, i'm the one who gets it. and when you take your first physics class, you will too. and temp is at the heart of the exhaust system. air temp, velocity, density, flow all are directly related. if you change one of them, they all change. the only way for a larger pipe to flow more air is if the source of the flow is also larger.




your air pump doesn't have to channel more air behind the constantly changing air it already put out in a contained path. once you contain the air flow (as in an exhaust) you can measure the pressure of the air flowing out.

yes and as a whole, i assume you mean from the ex ports back.

Well it looks like we have come to terms but all im saying is if EGTs did matter, then that would be factored in when creating an exhuast system. But its not, its not as important as the intake becuase your not really using the wasted gases. You want it out of there as fast as it can while style flowing alot of air, whether hot or cold.

agreed..........

Didn't Shelby say something about horsepower selling cars and torque winning races?

Huh...

Anyways, so I saw this thread. I got a 4-2-1 race header from dcsports and 2.5" exhaust, I was wondering where to get a 2.5" testpipe. I got a high flow cat, but I want to test it out with a testpipe. Suggestions? So much junk on ebay, I don't want to get something that doesn't fit or is rusted when I get it.

Almedarj

i haven't seen one that i would buy but then i went with a 3in exhaust i tried a buddys car with a 2.5in cat backand you cant tell the difference in terms of performance but the sound is so much better with a 3in

Your kidding right?

Stock SR turbo set up? T25 is garbage, HX35 and call it a day, cheaper than a crappy T25.


This whole thread is full of FAIL.

Both ka-t and n/a. Also my best advice is to avoid zilvia for KA material. I love all zilvians but when it comes to KA's 95% of the members are worthless as was proved again several times in this thread. Granted no one tolerates stupidity to thoroughly search before posting any questions.

Are you talking out your ASS. I'm making 162 to the wheels stock internals and haven't even spent over $1100 yet. From stock thats over 40WHP. You will never find a cheap turbo bolt on application for under a grand and make 40WHP, seriously.

like umsports said....check out ka-t.org. tons of info!

Almedarj

i checked out ka-t and plenty of info for me found there thats deffinatly a good place to look but its all about forced induction there. Theres only like a few guys there talking about an NA/KA

2ndcar

If you want to do a NA/KA build then do it. I'm sticking with the KA for my DD. But it all depends on what you want from YOUR car.

!!chuy!!

im planning on doing the same thing on my ka,de... get ported/polished, slitely bigger injectors,fuel pump, cams, and slap on a t28 from an Rb25. is there anyone whos done a similar build? and how much power are u seeing?
Or should i save my money and get a sr front clip....?

Almedarj

don't get an sr i've had too many friends get popped by the police and then sent to the state ref and then they've lost all of that money, if you have a dd and then a fun car do it to the fun car

BigVinnie

I've seen more sr valve trains blow up than KA valve trains.. A lot of these guys these days think that you can rev the piss out of the sr. Fact is it's just as revable as the KA. Piston speed on the KA is a little faster on upward momentum, but the bucket hydraulic valve assembly is way more reliable than the sr's valve train.

I know 2tone1via is such a douche. Talks before he thinks, just like 80% of this forum.

KA-T all day. Well over 300hp @ 10psi daily driver. NA is just so much work and money for such little gains on pretty much any motor.

Whats your gas mileage like? 12mpg at WOT? That's really efficient.
Just go turbo mad hp with shitty gas mileage loads of fun boys and girls...LOL

Hmmm don't really drive at WOT everywhere I go so my gas mileage is fine. I thought this thread was about performance increase on a KADE motor not gas mileage. And since when is 300hp "mad hp"? I guess I must be in the "dick head" thread I meant to post somewhere else

I would go KA-T if #1 I didn't live in cali #2 there was a good intake for the KA. The horrible intake seems to take so much to overcome na or forced induction. I guess we will see how good the upper intake is with the recent KA-Rs popping up.

I'm still going V8 at some point down the road.

No reason to be asinine. the thread states ka24de performance. Not ka24de-t performance, no need to be a douche bag and say something stupid like , "oh just slap a turbo on it and make that thing go, get 300HP". That's pretty much what you said in a nut shell.
