I've got an Apexi N1 /w silencer. I'm not a big fan...

I have the non-sequential and w/o the silencer it will over boost beyond my stock intercooler and Petit computer can handle.

With the silencer in, I never have a problem with the wastegaste keeping up... but I am down power and it sounds bad (not that bad).

Are there baffles or something I can put in the muffler to experient with flow? I'd rather not drill holes in the silencer because it may weaken the metal.

Thanks, Thanh

 

what are your mods?

 

Yeah, if you already have a mid-pipe, since you already have a pettit ecu (Greatest ECU in the world), you could try a resonated mid-pipe. Or, a high-flow cat maybe.

 

i put a restrictor in my intake so i could keep the apex gt spec + midpipe sound without boost creep. you might want to try something like that. i could provide more details if you want.

 

WTF??? pettie ecu greatest ecu in the work??? i dont think so!

 

My setup:
Apexi Power Intake
Street Port Motor
Non sequential /w ported wastegate
Stock IC
DP,MP, into an N1 /w silencer
Manual boost controller
Pulleys
clutch, cooling system upgrades

Restrictor in the intake???? Please elaborate.

With the Apexi silencer out, the boost spool time is very small compared to it /w the silencer in. I feel more power w/o the tip and it sounds damn awesome. Almost like that JUN Supra but with a rotary bite. Just mean.

I'd think an intake restrictor would be easier to make than an exhaust restictor. I thought about drilling 2 1" diameter holes into the silencer. A bit ghetto...

 

I have N1 Dual and I know what you mean.. i'm running seq twins, full exhaust..

My car is loud.. with silencer.. its little better..

But I also have boost spikes without the silencers.. also spools quicker by couple of hundred RPM..

 

port the wastegate

 

Thats what BNR told me.. I'm going to do it when I replace my turbos.. should be within next 6 months..

 

My wastegate is already ported. It's the stockers, so it's internal, correct? What a PIA, but I guess it has its reasons.

 

LOL!!! I meant that for when the Power FC is not yet within financial reach. You can't go wrong buying one of these from someone for $400-450 bucks. That's all. Sheesh!!!
