Re: Dave's Evo X Build/The Life of Dave blog
I should have some new parts today that I will post up pics of when I get them for the Evo, nothing huge but some needed stuff in my mind to polish off the setup. Still too cold to install them in my non heated garage, but can't wait for it to warm up to start wrenching again!
On another note, this was just posted on Evoxforums.
Twinscroll t4 ETS kit, 6466 turbo, ~1.0AR.
Seriously, this spools identical to mine, faster really, makes almost 700whp on 26psi! This on 35psi would be almost 800whp! I know what I am doing if I upgrade....might have to sell my new gun for this shit!

Re: Dave's Evo X Build/The Life of Dave blog
That's a fucking beast mode powerband, Dave.
What size motor was that on?

Sleeved 2.0L and stock compression, I could be looking at sub 4k spool on my setup. I really really don't want to touch my setup, but this powerband is beast mode for sure, I know of several other people switching to this already now just because of this guys' success. They were having boost holding issues with the twin 38mm wg's as they were the single springs. They are going to try 35psi when they get new springs. No crazy mivec or timing on this either, e85 though.
The guy with this graph is going for the X HP record right now and bringing the car to TX2013 or whatever the texas thing is called.

Amen. You will put yourself in the poor house quick trying to keep up with the Jones'. There's always something newer, better, etc coming out. Just focus on perfecting your setup, touching things that you haven't already touched.
What is different on your car that would allow you to reach the same boost level at less RPM than that one?
Edit: Ah just saw in your sig you are 2.2L.

Yep, 2.2L, from what I have seen the overbore is good for 400-500rpms of spool and making 8-12% more power at the same boost and then even a bit more power at the same boost with bumped compression.
I am not really trying to "keep up" with anyone at all. Just looking at the next step for improving my car. This is a slam dunk if I really want the whole big time turbo setup. But realistically its prolly not going to happen, not this year. Honestly, I just thought it was an AWESOME setup/powerband that got me giddy and wanted to share with everyone. Didn't seem worth making a whole thread for it. I have enough work on my current setup before I move up still.

Re: Dave's Evo X Build/The Life of Dave blog
That twin scroll 6466 looks nice. I wonder if the 1.0 A/R exhaust housing would choke it at all at higher boost levels.
One thing though, even though it is fully spooled at 4000RPMs, it doesn't look like the motor is able able to due much with the air since the HP and TQ at 4000RPMs are nothing crazy even though it's spooled up.

Re: Dave's Evo X Build/The Life of Dave blog
don't forget to differentiate 'spool' vs 'boost threshold' ....I'm sure it might have a decent boost threshold (4000rpm) but stomping on the gas at 4000rpm will probably be a pretty different experience in your car with the ef4 vs that one.

Re: Dave's Evo X Build/The Life of Dave blog
Dont change your set up. Leave the poor car alone and just drive it. If you want to throw money at something. Join halon cornfed and I in build a monster dsm for the track and the street.

This may sound like a newb question, but can anyone explain why this is, in layman's terms?
Guess I'm used to seeing the TQ line at least somewhat resemble the boost line, so this doesn't compute in my head. Usually I'm used to seeing when the boost line starts rising rapidly, so does the TQ line. Then when full boost is reached and the boost line tapers/flattens out, the TQ line isn't to far behind.
I think if I was going after a very fast spooling setup, and I managed to get a setup to spool as quickly as that one does, just to find out on the dyno that even though it spools fast it doesn't matter...
Random evo dyno charts as an example of what makes sense in my head:

Re: Dave's Evo X Build/The Life of Dave blog
That engine is not efficient at the lower RPM & flow. This could be for many reasons, extremely ported head, really big cams, etc. You can tell it was built for high RPM as the power doesn't fall off at all up top.

The motor isn't big enough or efficient enough at that specific rpm to use the air.
People always get all hyped about variable vane turbos, spool valves, or other tricks, so they can have the dream 1000whp turbo that spools at 1500rpms. But even if you get that to happen, it doesn't mean the car will make any power. That dyno chart seems to be a great example. It obviously hits full spool well before it starts making good power. That's not a bad thing, since it's probably decently responsive or at respooling at higher RPMs for a turbo that size. Maybe that Evo has cams and and intake manifold that give up low/mid range power for top end.
But anyways... Here is a helpful way to think about it. First off, a turbo is not like a roots style/positive displacement supercharger. It is not designed to make boost by stacking air and holding it it. A turbo makes boost inside the compressor housing and sends the air on it's way to the intercooler, engine, etc. So when you put a big turbo on a small motor and you get that turbo to spool really fast what happens? You get compressor surge. What is compressor surge? It is when the turbo puts out more air than the engine can take in and the air starts backing up and eventually backs all the way up to the turbo itself which causes the comp wheel to drastically slow down or stop(this is bad and very hard on a turbo). Compressor surge goes away as you go up in the RPMs because engine can finally use all that air. So what does an anti-surge/port shroud compressor housing do? It lets that excess air flow back out into the intake pipe in front of the turbo, so you are essentially just wasting some of the boost/air you worked so hard to build. It is also better to run a non-anti surge compressor housing if you don't need one, they usually make a little better power.
In other words, you can't have your cake and eat it too.

Re: Dave's Evo X Build/The Life of Dave blog
So it's an engine thing, not a turbo thing, is what you're saying? The engine is full more or less (air-wise), it can't use or do anything more with any more air at that rpm range.
So with that being said, really any turbo setup would not make more power at that RPM range either, whether it be a stock turbo, EF2, etc. Because this is purely an engine thing, and the PTE is already packing it as full as it can get with air.

That would make sense I guess as my EF4 could spool by like 3500 with mivec, but it just surged like crazy. I am guessing the PTE turbo's surge ports work a bit better than the EF4 ones which is why spool is so soon on this thing.

Re: Dave's Evo X Build/The Life of Dave blog
That is awesome, I say do it.
Is there anyone local making good power on a 6466? I haven't seen one outpower a 6266.

Re: Dave's Evo X Build/The Life of Dave blog
You can get a 6266 or 6766 for half the cost of a 6466, so it's probably not going to be that commonly used.
