OK guys went to ESP last Saturday( 16th), Cobb AP tuned 291 WHP and 312 WTQ( Mustang dyno).Tuned for 20 PSI ZERO knock.. Props to Mike and Dave, Thanx guys. Dyno sheets should be emailed to me today.. Lets just say this thing HTIS HARD.. ***street racing removed by mod***very happy and this is definitly a option for guys looking to make some good power and staying direct bolt on.

Nice numbers! Now save for forged slugs and rods and hope for no zoom zoom boom.
You have an upgraded fuel pump right? Don't see it in your sig.
 
Yea I have the PTP internals. Did that a while ago, May need to update the sid again, LOL
 
Max power at 6200? That is awesome, I was a little let down for you when I saw that max was only 291. But it is a mustang, which reads lower, and all that power at 6200 is definitely proof that the reworked k04 is worth it, grats man.
 
Yea I almost got caught up on the 291 also, But they reminded me it reads lower than the others. ***street racing removed by mod*** :)

What if you got protuned and then down the road got the reworked turbo? Would you need to retune?
 
Yes you would the Reworked flows 30% more air( They say) But you can see that on my Dyno Power is all the way past 6k the stock K04 falls flat at 5k.
 
hmm you're probably right, makes sense that you would need a tune. I just remember hearing that one of the benefits of getting a reworked is that you can still run the same amount of boost so you don't need a tune. But if you're making more hp then that means more fuel, timing, etc. so i dunno
 
I am glad that anm6 found a tune that would work for his higher flowing reworked K04. HT tune would not handle that much more flow.

Anm6, those are fabulous numbers on a Mustang dyno. I don't think anyone can get a stock K04 anywhere near that on any tune without blowing up!

But I must respectfully disagree that the stock K04 falls flat at 5k rpm. With the HT tune (Excel map) and mods below, I am producing good power out to at least 6,200 rpm before any significant fall off. Attached is a G-Tech accelerometer data log on power produced in a fourth gear pull.

BTW: On the Gen 1 MS3, gearing is 16.0 mph per 1,000 rpm, according to Mazda specs, so do the math. This is an almost flat power curve from about 4,000 rpm to where I let off at 6,200 rpm. The two runs were made back to back on the same road in opposite directions to account for any uneven or unlevel surface (it is almost ruler flat) and any variations in wind.

I am also attaching a link to the power loss through drag calculator. Because the car is not stationary, G-Tech uses real world conditions out on the road and the engine must push the car through the aerodyamic drag of the air, you have to allow for frontal area and drag coefficient. Frontal area on our cars is 25.5 square feet, and drag coefficient is .32, both according to Mazda's specs.

This means that the "dyno" numbers on the chart are deflated by about 12 horsepower at 60 mph and a whopping 50 horsepower at the point where I ended the run. But seriously, as with a chassis dyno, the numbers are really just calculations. In this case they come from the accelerometer's measurement of g forces. So you can't take them as absolutes, but rather as relative numbers. The point is that the stock K04 can be safely tuned with HT to produce a good, flat power curve out beyond 6,000 rpm.

When taking into account the considerable increasing effect of drag, this tune is still building more power above 5,000 rpm. For hp to remain essentially flat at is peak as the effect of drag increased with speed was a huge and nice surprise.

Not to jack the thread, just wanting to point out that good and safe tunes can extend the power curve on the stock turbo too.

Great info, as always!


But wait! HyperTech did a special dyno test, with exhaust and Cai. If the numbers are accurate, they as good as his. See below.

Of course great INFO. I was only saying the stock K04 with out any tune of any kind.. :)

Remember I had the HT the car made power above the 5k and pulled to 6k.. But on the stock fail tune it falls of a cliff. I was very pleased with my HT and would do it all over again if I was stil on the stock turbo..
 
Hey anm6!
Qust a quick Q! Did you make hard research before going PG reworked? Did you consider going PTP SST instead?
Just wondering what way should I go - PG reworked, PTP reworked, or hybrid from BNR with GT28 central assembly... Too many options and each has its benefits...
If someone has some pros and contras in mind - I highly appreciate if he shares them here :)
Thank you!

[EDIT] By the way, anm6! I remember you was complaining your numbers are not so high but you are fully bolted. I can say that adding tubular mani made VERY nice punch to me! Stocker got VERY fast spooling with it, and very smooth flow also! Just FYI! I am still happy with it, but put it on a month ago.

PtP is in bankruptcy court, Chapter 7 so, I wouldn't go that way if I were thinking of it.

The story's pretty ugly, if anyone cares.
 
Now I have no problems with the one part I have from PtP on my car (internals) but, this is old news from elsewhere. The business has, according to John, been sold to his mother in law before the proceeding, which is a pretty obvious way of trying to shelter assests, in my view.

For those that have not heard, John/PTP are due in Chapter 7 (liquidation) bankruptcy court in Seattle next Thursday, October 14, 2010. Since John and his wife are sole proprietors, PTP and all their other DBA's are not separate from their personal assets and liabilities.

If you or any member or vendor that you know of have any outstanding issues with John/PTP including but not limited to needing warranty repair/replacement, products/services owed, or money owed, please contact myself and giggles and John/PTP's bankruptcy attorney ASAP. I have also contacted my local business attorney for advice in case we need local representation.

It's possible we are s*** out of luck, but at least we can give it our best shot.

341 Hearing Date & Time: 10/14/2010 02:30 PM
Case Number: 10-20828-SJS
Names: John E Bushbaum, Regina M Bushbaum
Attorney: Jay S Jump
U.S. Bankruptcy Court - Western District of Washington.
Jump Law Group - Bankruptcy Attorney Seattle, WA. Richland, Pasco, Kennewick, Kent, Davenport, Spokane, Auburn, Puyallup, Federal Way, Renton, Washington Offices
 
[Yea I did tons of looking around read many differnt things, Ways to go ETC, I went this way cause if fit my buget.. I did not have to pay a core fee, An I did not lose the car to send mine in. The numbers I have now I'm very happy with, the numbers that where not so good where on the HT with the Reworked,. .. But happy now.. Next mod will be the Manifold for sure, Or maybe Bronze wheels??
