Increase After Mods?

[BillyMako]

My R32 GTR is currently stock apart from cat back exhaust with compliance cat. Making 180rwkw on 12psi crappy boost controller around 12psi drops to 11psi.

I am wondering what increase i'll get once i put on a pair of HKS pod filters, aftermarket Mines front pipe from cat to dumps, a new HDI boost controller and high flow cat.

[NYTSKY]

Maybe 20kw.

[PAV34]

yeah 20kw is about right.

Hmm i made 200rwkw with my old catback, compliance cat, Pod filters & 13psi.

Here is my dyno sheet with the crappy boost controller and cat back exhaust.

i have pfc pods stock dumps, front pipes 3inch cat exhuast straight tho to cannon 13psi 262rwkw

12.0 on the 1/4 mile bad traction....

[R31Nismoid]

leave the stock airbox on

[PHA71L]

i would do the cat and front pipes next... cat will prob make the biggest differnce....

[BillyMako]

so i'm looking at about a 20kw incerase.

What if i also add a power fc while keeping the same boost?

[PHA71L]

pfc 1300 with hand cont plus a tune 400 500 some pay even more for a tune 750...

you would have to get 20kw easy if not more and better responce better on fuel also

[PHA71L]

if i was you i would put a decent air filter first in the stock air box say what 100bucks?

then either front pipes or cat next or both at the same time

then get a decent boost cont ebc leave the boost on stock tho

then a pfc

plus a tune then up the boost to around 12 13psi max on the stock turbos the power from stock boost 8 or 9 to 12 13 makes a big differnce!

by then you would need a good clutch to if you dont all ready have one

[R31Nismoid]

Basic format goes like this:

Exhaust (can keep stock dumps) + PFC + cam gears + 1bar boost = 250rwkw on stock turbos.

So 12psi its feasible you would be around 210-220rwkw depending on the dyno

Its more about driveability than anything. With the tider mixtures etc the car will driver nicer more so than make outright power.

[BillyMako]

220rwkw and i'll be happy.

I have a pair of HKS Sports filters, Mines front pipe and getting an X-Force High flow cat.

I am also looking for a Power FC but without the hand controller for now.

I'm also think of getting a pair of adjustable cam gears.
