GReddy Kit + D16Y1 SOHC VTec E-manage Untuned = 97.5WKW Not Bad!!

Are you getting a full 2.5", or 2" downpipe with 2.5" catback ?

Not to sure

I'll have to think about it

[1996ek1]

I say go full 2.5!

Althought shouldnt you have got it tuned after you get the exhaust done?

Yeah you should..

Its my understanding that when the gas leaves the manifold hot it can go through smaller spaces thus you can go from say 2" to 2.5" as the gas cools down it expands...

Not sure how true this is but that's what heat wrap on heaters dose, keeps em hot to the gas moves faster...

Someone correct me if I'm wrong?

Hot shit is usually more expanded

Thats why they tell u to keep deoderant outta the sun

hey, nice build, i cant wait for mine.
i've got a 2.5" exhaust system, its piss quiet, not even loud on boost either.
ends with a cannon muffler.

However Im upgrading to 3", if your interested, let me know. I'll pull it out for you, you should feel gains straight away with a bigger exhaust system.

Yeah but that's compressed already..

Header wrap list's the benefit of using the wrap is that the wrap keeps the header hot and increases gas flow..

Quote:
Header wraps are designed to keep the heat in the header to improve scavenging of the cylinders. Keeping the heat in the header allows the exhaust speed to remain high. (the right idea)

[Limbo]

it helps scavenging and it keeps the heat in the engine bay lower.

I've wrapped my dump pipe. That's also part of the issue why its not done yet

[grumpy rooster]

On a turbo setup, the bigger the exhaust and dump pipe the better. ie a 2.5-3" dump and exhaust would see you make some decent gains.

Yeah I might have to do that..


It dose feel like I'm missing out on power somewhere lol

hey dude i'll give you a ride in mine this sat if you want i'm gonna go see adrian to tune her up.
Just fired her up today and she purrs great. Can't tell it hasn't been tuned.
But it does have a turbo base map

I got all my exhuast done to 2.5"

Sweet bro
Good to hear man

I'm books for next week final tune 2nd

Let me know how she goes

What boost ECU are you running?

Its a big drive for me anyway lol

[Limbo]

running PFC.
Turned on AC & stuff also and it didn't miss a beat.
Might need to change the BOV spring through cos it seems abit off.
Since i plumbed back it had an extra spring but i think i'll go back to the original spring
