You miss the point entirely which is that the data is a much more accurate indicator of power than a dyno chart. Then you add in some nonsense non sequitur about 900000 dyno horsepower actually being 4 hp which is not actually physics,just nonsense... The motor may accelerate more slowly with a heavier load but that does not change the power it is making to move the load...

Airflow timing boost RPM are not going to vary hugely among motors making similar power. We know what kind of airflow and timing it takes to make given power levels so it's easy to extrapolate from the data what's actually going on. BTW I have a degree in physics and aeronautical engineering...

Power = work/time; so for a given amount of power it will take more or less time to do work which is based on the weight of your car and the acceleration. SO a 300WHP car that weighs 2700 lbs accelerates faster than a car that wieghs 3300 lbs with the same power. Power does not change but the rate of acceleration does which changes the time to do the increased amount of work...

Thank you for the correction on the 90000/4 hp thing, i was thinkin too fast, do that sometimes. hehe

Though things like rotating mass will have an effect on hp.

Thoughts on my #s?

It's like holy crap you are logging too many parameters... The log is only to 4.6KRPM. You pull ~194 g/s at that point which is about 260 at the crank if your timing is good. Timing is 14* which ain't that aggressive for 19 psi. It's a long way from 300 at the wheels. You probably actually peaked out at about 300 at the crank which is like 230-240 ATW being optimistic...

On the other hand here is a log from a very aggressive 2.1 stroker

now at 4.5K this motor is flowing 45% more air and a bit less timing, lower IAT than your car. If your car was putting up 300WHP then this motor was making 430+ on a small 16G with an EWG? je pense que non....

You made an assumption that crank HP = WHP which therein lies your problem..

I'll give you credit for posting a 250-260 WHP log... No way it approaches 300WHP.

Same car, small 16G, and it would make 300WHP on almost any dyno. Actual power between 300 and 320 ATW. A little less aggressive on top AFR's 12.1 peak torque and 11.9 at power peak. It's a small 16G so notice how it's pretty much all packed up and done by 5.8KRPM with this boost curve.

Then you understand that you are nowhere near 300WHP of airflow regardless of what any dyno chart says.

WICKED! I started this thread (well actually the "PT Monstah" TD04 turbo with 19T compressor and TD04H hotside part of it) in what seems like a lifetime ago... it's nice to know it's still killing it. Happy conceptual designing and wrenching (always in that order)

BTW: I sold my GF8 that put down 262.5 awhp cf:1.28 (posting #1300) with this turbo about 3/4 years ago to a friend and the motor is currently being rebuilt and slightly built-up (excited!) due to high mileage but the turbo is still running like a champion --- NO FLAWS or FAILURES AT ALL.

Well I'm going to pick up a blown up 2008 wrx turbo this week. It needs a new comp wheel and housing. So its going to be getting a Kinugawa billet 19t wheel and comp cover and STS turbine wheel and rebuild it. I should be all in for under $500. Kinugawa claims there that their billet comp wheel flows enough air to support 30% more power than the 13t. So that would put my car into the 300hp neighborhood, especially with the STS turbine wheel, which should be the highest flowing and lightest turbine wheel that fits in the 6cm housing.

^^ Cool!
They also balance the whole rotating mass for that price?

Is it a 'send-in your old unit and receive the upgraded one a few eeeks later'- deal?

No, this is I order a bunch of parts and lay them out on my tool bench and a couple hours later I have a rebuilt turbo. That I need to take to a local balancer to get balanced. Though I'm considering not having it balanced since the components are neutrally balanced individually, so in theory there is only a very minute chance they wont be within acceptable balance when put together. This is the reason I bought an 08 td04 so I wouldnt have to machine the center housing for the larger exducer of the 19t wheel.

How reliable are these td04 19t's? and what are reliable shops that can build them from a stock td04?

Yes. I pulled the 08wrx td04 apart, its not a 19t. CHARA is only machined to 56mm and not 59.7 (IIRC thats the right size for the 19t). The wheel almost seems like its a 15t rather than a 13t though because its a bit big. I think I'm just going to double check the wheel, buy a new stock wheel and a rebuild kit and then just ebay it away as a rebuilt td04.

Reliable as stock, as the rebuilds use stock. check out Blouch Turbo. the 19T rebuild isnt on their website but they still do them.

For those interested I've got one for sale in the Nasioc classifieds. I had the 19t on an 06 2.5l engine for ~15000 miles. It performed well. Dyno results are in EFI Logics dyno database under Konrad Mann. Search my username to locate the 19t f/s classified.

Regards

I'm currently running a TD04-20T. Bought a used TD04-13T and then converted it using the Kinugawa 20T kit. Works good. Running on home tune at the moment and will need to get it on a dyno for real numbers.

Who did you have machine the bearing housing? Or are the now selling a 13t upgrade that has the same back plate size as the 13t.

I had a local machine shop machine the bearing housing to work with he 20T wheel.Then I rebuild it using an eBay kit and then ported/polished it. This one is using an 04 WRX TD04, so I believe its just TD04-20T. Not HL. I do have the original 13T housing if that's what you're asking about. I'll post the DIY when I get a chance.

I am actually selling a spare TD04 that I have. Could perform the conversion+PnP+Rebuild if anyone wants it.

I love the way it perform so much, that I might pick up their TD04HL-20T for a little added power.

ok, cool. Supposedly there is a company making upgrades for one of the volvo compressor sizes like the 15t or something that are designed to drop onto the bearing housing without machining. Now that would make a nifty upgrade. I've got a 13t from an 08 wrx just chilling in pieces after finding out that the rumors werent true and its not a 19t.

why not take it apart and see? The intake end diameter and wheel diameter should be able to tell you if it is indeed a 19T.

Well, I mean its in pieces on my work bench because I pulled it apart to measure the exducer... It needs a rebuild and a new comp wheel and one of the typical broken 08 wrx bolts extracted then I'll probably ebay it.
