Dude I would lick the scar if it got me more power.
Sir, Dan has an ETS exhaust and I think its one of the best sounding systems Ive ever heard. Very throaty and growls.

 

my iphone causes all kinds of typos. i meant parts.

you'll probably make 330 to 345 after the tune. the 3 port solenoid would be my next mod along with cams. the only thing going against you is the amount of boost and timing you can run with pump gas. that set up on e85 i'd bet would get you at least to 370 on that dyno or more. on e85 and the stock turbo the boost is totally maxed out as far as i know.

if pete's tuning it, he'll tell you all about what he can and can't do.

 

i doubt you'll max it out on pump gas. there are people holding 30 psi on e85 on the stock turbo using the 3 port and wastegate mods.

i am not a tuner but you'll probably be anywhere between 24-26 psi i bet......that's because i'm a betting man i live dangerously.

 

You did write "PARTS", I read it as "PANTS", gotta get my eyes checked.

Was that directed to me? I agree, I really love the ETS growl, but I got it with the resonator and HFC to ensure it wasn't too loud for the VA Roads. By now all of you must've figured out how much VA sucks for performance junkies. The only thing I did not get is the DP. I'll be doing that with the turbo swap next year or maybe even sooner if finances permit. This is what I do every year:

Months 1- 3 : Save all money earned for long term savings.
Month 4 - 6 : Spend it crazy on stuff I want.
Month 7 - 9 : Save again
Month 10 - 12 : Spend again.

I'm a contractor and don't have a 401K etc, so I just save up whatever I can for the rainy day. Its worked fine so far for me. I have both the cars paid off too so its all cool.


Haven't spoken to Pete directly yet, I did not want to waste his time before the car was ready for a tune. I figured I'll just do everything and then drop him a line.

 

I can say 24-26 with confidence. I don't think any tuner will boost than that on 93 and tell you to your face it's a safe tune. However, I will leave it to the expert tuners to tell you whats best.

 

Any audiophiles here? I need a double din navi unit for my nice new orbital kit waiting to be installed.

eyeing the pioneer x920bt or the alpine w900

 

Did you consider this?

Its not for you if you just want it do whatever you want. you'll need to tinker a little bit with it.

 

pete tiebout is the guy to talk to about audio stuff.

 

since apparently certain "people" thought I died, just figured i would drop in and say hi. hope everyone is doing good. battling allergies, teachers, finals etc. later guys (and no new injuries to report mr. chu) haha

 

Dd any of you look at this thread?

He's doing 38 psi on a stock 9 turbo. I knew the 9 had a bigger turbo than the 8, but damn that's high. Can the turbo on the X even hope to put out that kind of PSI?

Also, People keep saying that the pump gas limits boost to around 26 PSI, is that due to the octane and burn characteristics of the gas or the turbo? Is the limitation the same no matter which turbo we use? I thought if you made more boost and pump more fuel using the injectors, the ratio is still kept safe. The only downside would be the timing. It'll probably need a little bit more advance to ensure all of the mixture burns and in the process, cause some knock.

 

Come on... you haven't hurt yourself at all? No good roofs to skydive off of?

 

Any turbo can run that high. It's how long it will run that way and how hot the charge air is as it leaves the compressor housing that really matters. There isn't a magic boost number that translates to power, it's all in the efficiency of the turbo. You can make more power at 20 PSI on a more efficient turbo than 40 PSI on a little one. The IX turbo is great but I can almost guarantee he won't make it more than 5-10K miles before it grenades. As boost increases so does the RPM the turbo is spinning, and the faster it spins the quicker the bearing surfaces wear due to lack of adequate lubrication and the various loads the shaft sees at upwards of 100000+ RPM. Simply put the oiling system can't keep up and the turbo was never designed to spin that quickly. A smaller mass wheel has to spin at a higher rate to reach that output. Advances in blade design have helped but there's only so much you can do before it becomes a rotational issue as opposed to blade design. It's compressor wheel and housing at a certain point stop being efficient and start blowing hot air. When the charge air is hot as it enters the engine it's causing pre-detonation and not making power Ie: knock. The pump gas limit is more detonation and engine based. Engine limitations aside, higher boost leads to higher cylinder pressure and if it gets too high, certain fuels can't properly combust without help of some sort and you also get pre-detonation then as well. Hope that makes sense I have a tendency to ramble on.

 

well said josh

 

what josh said.

and what pete said earlier. it just starts blowing hot air.

the replies definitely reflect the personalities.

 

i may show how little i know but physical properties aside doesn't the boost controler (whatever may be controling) start creating an obstacle as you increase boost to super high levels?

idk. i am going to stop posting. i know what i want to ask but the brain shut off already.
