What is max power from stock turbo & auto?

[shav]

I would have said water to air was for people trying to chase maximum throttle response, seeing as the inlet tract would be about 8 feet shorter than the FMIC. FMIC is still the best option for HP in my opinion, just be aware that it will induce a little lag.
That said. A good bolt on TMIC, a good exhaust and a good tune is all you will need. Don't get too hung up on dyno numbers, otherwise you will just end up sad when you don't meet your targets.

I agree. numbers are just numbers. However, as a reference is all I would use it for. Essentially all I'd want to do it get good 0-100 times as the car is 100% daily driven and needs to maintain reliability/driveability.

Mine to is a daily, but I am a little soft in the head.

Hey guys, I tried to do a search for the past half hour and couldnt find what I wanted.

Just wanting to know what the max power atw someone has gotten from running the stock turbo and auto gearbox, but with aftermarket bolts ons, like TBE, TMIC, BOV, Injectors, Fuel Pump, & KiDo tune etc.

Also is it beneficial/worthwhile to run a bigger trans cooler to help longevity of the trans?

FWIW, I'd like to try and get better 0-100 times. No interested in 1/4 much or track racing. Looking for better/faster throttle response and torque.

Hey Shav

My GT is an auto and I got 170kw atw with just a dump pipe, TMIC and a tune (check out my profile thread).

I later added a Mild Steel X Force 3 inch centre and Y pipe with a retune (still 170kw atw).
It didn't lift my peak power at all but i got much more power and torque in the low end and mid ranges which made it much more enjoyable to drive around town.
I would recommend you upgrading the intercooler if you have plans to upgrade your turbo at a later stage.
Just a Turbo Back Exhaust and decent tune should see you get around the 170kw mark (+ or - 5kw).
Once you get this done it will put a big smile across your face every time you push the loud pedal

That's awesome Peter. Great results. That's basically what Im looking for. So are u running stock mufflers?

Ill check your thread out.

yep, stock mufflers to keep it quiet.

You will only make another 3-4kw at peak revs with after market mufflers (stock turbo) and they're as loud as hell on an auto wagon. They also drone like a bitch.

Unless the mufflers are providing an exh pressure drop at stock boost levels, in which case it will limit the turbo's efficiency and thus affect its ability to run more boost and thereby cost you ALOT of power.

I wanna avoid that like the plague. I might change the tips but keep the mufflers as I want maximum stealth with sound.

How much power loss is there running stock turbo and mufflers, but with dump and tmic?

[PoidaGT]

My tuner (MSR) reckons i'm only losing 3-4 kw at 6500rpm with the standard mufflers fitted. It might be a few extra kw now that i'm running a bigger turbo.

I couldn't live with the noise and drone from the aftermarket mufflers so i sold them and put the stockers back on.

It wouldn't be nearly as loud in a sedan (on the inside).

[peadya100]

Total newb question.
Are you guys suggesting running an after market exhaust and cat with the stock mufflers? If so do you still use a 3" exhaust?

I'm looking at buying a gtb as we speak and this thead is answering all of my questions beautifully!

[alexeiwoody]

Some aftermarket mufflers drone on an auto, and wagon is worse off than the sedan. Hence going with stock mufflers is the easiest way to deal with that. You can also try finding aftermarket mufflers that don't drone.

Most people on here would have a 3" exhaust from what I've seen. The stock mufflers aren't 3", and you'll be holding some power back compared to better flowing mufflers with a 3" inlet. Only 5kwish so if you've an auto and can't be bothered finding good aftermarket muffs - stockies wouldn't be as annoying.

Awww, mine only dyno'd at 156kw atw with similar mods LOL (done TMIC, dump pipe, mufflers)

Shav, in regards to mufflers, Matt was able to tune out some cruising speed drone for me - I could barely hear it over the road noise driving out to the track on Monday. I've got the TCP Quads. You still get a nice noise when driving hard, but if it's just cruising it's fairly chill. I just wish I could replicate the external exhaust note inside the cabin fully when driving hard. I sent Karl out in my car for a bit on Monday to get an opinion on some issues I was having, and I went and stood by the fence while he was doing laps. I'd say it was one of the quieter cars out there (although louder than Daniel's with the stock STi quads) but it sounded fantastic

[alexeiwoody]

I'm making 160kwaw with dump, muffs, inlet pipe. Matt said there was probably another 5kw in there once the engine and tmic cools.

Your lucky, im only making 159.8 in my auto with a VF52 and a heap of bolt ones and forged pistons :S

i have a dyno sheet up on my build thread (viewtopic.php?f=10&t=20193) im a bit disappointing now that other with autos are getting such higher power figures or about the same with a stock turbo :S

[shav]

When the time comes, I'm gonna stick with the stock mufflers. From the research that I have found, you'll be paying a good 500 bucks for after market mufflers, gain another 5kw and have a louder exhaust, that's cash I'd rather put towards other things like suspenstion which will give greater bang for buck. Im passed that ricer boy BS and I would rather the stealth appeal. Keep the stock muffs but improve the mid and Y piece, do the dump pipe (seriously considering PHAT dump), TMIC (see what PHAT has to offer on that. Still tossing up between AVO, Perrin or Process West), 3 port boost solenoid and a retune. If I get about at least 160kw at the wheels, significantly improved lower and mid range torque/power and faster 0-100km times, I'd be pretty happy. Then again I'd love to get closer to 180kwatw but I know it may be a pipe dream.
