Defined Autoworks 523whp 35r!!

[Rotary no Densetsu]

Hell yeah man, this thing is so badass.

[Force13b]

Sounds awesome! Bad ass build right there.

Is the 523 Hp Whp or corrected to flywheel Hp by a conversion ratio? [I saw the Torque (flywheel) on the bottom]

Do you have a dyno plot that shows the AFR? I am curious how lean you went.

It would appear from the power curve that you were lean of 12:1. If not, that is an impressive plot indeed.

Its wheel horse power. We made sure on the dynapak the everything was like it should be. We were not running lean at all. I am running two denso pumps in the tank. We had a wide band on the car, when we were tunning. The fuel was holding in there, and appears to have more. I am going to try to get it back on the dyno before winter.

Correct it is Wheel horsepower. Dyna packs read actual wheel torque, which in this case was 1,578 ft-lbs. But of course that isnt easily translated, so you select to view "flywheel torque". But its not actual flywheel torque of course.

ultimately ou cannot say anything until you see the sheet with the TCF listed as 1.00 (which is not on the screens provided).

I.E. Like this >



I can take his word but this sheet will silence any doubters

p.s. lots of shops put in different TCF values (which are not shown on other screens) to guess flywheel HP or to correct for other types of dyno standards that return higher numbers.

[GtoRx7]

We are going back to the dyno monday, so I will be sure to save the TCF values, and boost charts. But as a side note, if there is a TCF value entered in the "flywheel power" and "power" will not be the same number. The flywheel power will be higher the exact percentage the user entered.

Impressive. Time for me to upgrade my old T04B60-1 Turbo.

Stupid question. My car does not make that backfiring popping noise. Only did that when I changed it to ignition cut. Is that ignition cut? (Ok I am stupid should read instead of just clicking the video link)

I run fuel cut. I always thought that ignition cut was bad.

Either way always impressed to see big numbers. For some reason the majority of us only make around 400rwhp. I hit 409rwhp about 7 years ago on a dynojet. i had to up the boost to 18psi to make 400rwhp on a mustang dyno.

Have fun with that beast.....

Regardless awsome work Logan!!! As for the 35R cant say enough about them good for street set-ups & weekend warriors! Did a 13B-PP with twin 35r made 972RWH @35psi (methanol)

Thank you! Peter (co-owner) is also responsible for building this car. It was his personal car originally as well I am glad Fdwarrior took the time to take it back to the dyno and let me re-tune it. It surprised everyone involved!

[GtoRx7]

Alot of people were wanting charts such as boost pressure, corrections etc. So here is pretty much everything I could think of that documents the results. Its still the highest 35r non-billet turbo 13b dyno chart backed by verified proof that I've seen posted. These numbers will be re-broken again I am sure on monday once we get back to the dyno again. But until then, enjoy!

First off is the charts showing TCF. And it of course is 1.00


Next up is the boost chart by itself


Then we have the boost chart and torque line to show relationships

[RICE RACING]

again very good job, those graphs should silence any doubters

For what its worth that (if you average all the runs) around ~7% to 8% more power at same peak rpm than what my old nugget had on 18psi running street port, plumb back waste gate, and 3" quiet exhaust system in 2002 on H trim (~57mm) compressor old T04B... S5 T2 engine block.

I wish you would post AFR on the graph (or are you not logging it to the dyno?)

I am curious what more experienced Turbo engine tuners run, as a lot of people I talk to say nothing lean of 11:1 and I think that is leaving a lot of power on the table.

Peak power (for pump gas) is 13.3:1 (0.9 lambda). There is not much gain to be had lean of 13.0:1. As far as I know, this holds true for any chamber pressure - it is definately true for naturally aspirated applications.

Your VE must be relatively high if you are running 11:1 AFR.

[TitaniumTT]

I run about .82L (12:1) I must not be very experienced or know what the hell I'm talking about at all.... I mean when people are making 437 RWHP with Meth @ 22psi on a GT42R.... I mean, how can I compare right?!?!?!?!?

In all seriousness, this are the things that I like to see. Convinces me even more that I'll be able to break the HP/Torque that I want to make with a very similar turbo.

Nice numbers.... Love the setup....great job

Honestly I should let Logan respond, but I would say he is about as experienced as it gets. He currently has the highest horsepower from a 2 rotor n/a using a street port. He also just made 421, with allot more left from an n/a 3 rotor using a street port and semi-p port. Rally I would not let any one else touch my car. I would sell my car before having to go some where else if those were my only two options. Im just talking from my experience as a customer, along with what I have seen come out of there shop. I know for a fact there is no other n/a 3 rotor that even comes close to his. Logan's semi-p port is almost touching documented full p-port numbers. I would not be concerned with experience.
