Change filter and cat-back give 40hp !

[Christiano]

I change the stock filter to a K&N Injection Kit. Removing the BCS and change the cat-back to a 3", had 40hp increase in powerfull. Amazing ! If you have some information about "how to make this better" please, talk with me !

you will notice more if you get a bigger downpipe

Get a MBC and -30 to +30 boost guage and set it at 15psi. You must upgrade your upper ic pipe and get a 1g bov for that tho, the stock 2g bov leaks above 12psi.

Thats if you havent melted a piston by removing the bcs.
20-21 psi on stock fuel system not good.

If hes still on the stock upper ic pipe and 2g bov he shouldnt have to worry to much since it leaks above 12psi.

But get a boost guage and MBC right away.

Was this on a DYNO? OR G-tech?

You're on your way to the boost bug. Now get a downpipe, UIP, and a MBC. Might want to re-wire the fuel pump, or get a new one altogether. It's a never-ending cycle...

oh yea forgot about that
ok then his turbo is pumping 20-21 psi and his bov is letting most out, which means whatever air that makes it into the cylinder detonates. :laugh:

Ok. So, I´ll need: downpipe, UIP, and a MBC
Somebody can explain what is this ?
downpipe ????
UIP ????
MBC ????
I just change the filter to a K&N and remove the BCS, and I do not change the cat-back yet. What do you think ? Remove the BCS was not a good idea ? If I change the cat-back (3") can be damage to the engine ?

 

[BoostinAWD]

Removing the bcs is not a good idea period, at least leave it plugged in.
Get a Boost guage, and a manual boost controller.
I dunno what kind of octane you have in brazil, but if you rewire your fuel pump and run premium you can run 15-16psi.

But you need an upper intercooler pipe and a 1g blow off valve to be able to go over 11-12 psi.

A turbo back will definetely help too.
Hope this helps a little.

Yes, help me, but I don´t remove the BCS totaly. Just remove that little restrictor of plastic, inside the pipe... this is not good too ?

You know a good place to send me some parts to Brazil ?
Thank´s
