Ryan Cruser's T04S dyno results...pics, vids, etc...
Just got back from a couple fun days of dyno tuning @ Excessive Motorsports in Hillsboro, OR. I'm posting this for Ryan because he is a self-proclaimed internet idiot and can't even attach pictures in his posts...
I'll try to be as complete as possible in recapping the last couple day's events...but some of it was slightly cloudly due to a some excessive alcohol consumption
Okay, first off Ryan's mods...
Atkins street port motor with 3k miles
XS Engineering T04S
Apexi Power FC
Apexi AVC-R
HKS Racing gate
M2 Medium SMIC
850cc primaries
1600cc secondaries in RP rail
BIG Bosch Motorsports in tank pump
SX Reg
midpipe
Apexi N1 Dual
HKS Twin Power
Those are the basics...but I might be mising something. At first Ryan was running the RP high flow pump, 550cc primaries, and 1200cc secondaries. He spoke with Ralph @ Excessive about the fuel and decided his setup would not support the power levels he wanted. At first they were just going to run 850cc x 1600cc...but later swapped out the fuel pump as well. According to Ralph this Bosch pump flows something like 120ghp @ 70 psi...not bad...
So pretty much all Thursday and some Friday morning was spent installing the fuel stuff, relocating the intake air temp sensor and some other misc tweaking.
Friday afternoon Ralph started the tuning on the dyno. Here are some pics...
Frank the magic machinist
Mustang Dynamometer
Ryan the pump bitch...PUMP BITCH PUMP! Nummy 108 octane!

Now for the good stuff...
Both Ryan and I thought the M2 Medium would be a limiting factor as far as big hp numbers. Not so at all. Ambient air was between 72-74 degrees the whole time, and intake air temps stuck around 90 degrees after quite a few hard runs. We did have a small fan blowing through...the IC did a pretty good job.
All runs were done in third gear. Fuel was about 1/2 92 pump and 1/2 108 aviation fuel.
We did have some issues with the wastegate/AVC-R controlling boost. Found out that the HKS gate was a 14 lb spring, when we needed a 10 lb spring.
Anyhow...here's a couple charts and vids. I'll just get right to the big one.
461 rwhp @ 20 psi, 7250 rpm. A/F ratio 12.5ish.

http://gt3540.com/vids/ryan_dyno_461hp.MPG
http://gt3540.com/vids/ryan_dyno_461hp2.MPG
Obviously these are some pretty decent numbers, but Ralph felt that it was pushing it a little to close to the edge. Next runs he added more fuel, and lowered the boost a lil bit.
Here was the next run. For some reason it didnt capture the A/F graph, so I don't have that to share
432 rwhp @ 18 psi, 6750 rpm. A/F ratio 11.8ish
http://gt3540.com/vids/ryan_dyno_432hp.MPG
Ralph still wasn't happy with the A/F on that one.
This is where we finished at. Unfortunately I didn't get a vid of this one.
419 rwhp @ 18 psi, 6750 rpm. A/F ratio 11.5ish
This morning Ralph did a little more tuning, including completely changing XS's timing maps. He pulled some timing out, and a little fuel. He didn't put it back on the dyno...but I'm guessing it's pushing more than the 419 he left off at last night.
Basically Ryan's car ******* hauls ***. Right after the tuning we went out for some spirited runs. The vids suck, as it was night...I was taking the vids with my digital camera (not a camcorder)...etc.
This vid is the *** end of a 0-110ish run. I didn't know they were gonna take off, and by the time I got the camera up and pushed the record button we we're already doing about 90. Ralph was driving with Ryan...I was filming from behind riding in another T04S FD running 15 psi.

Just an FYI, all the tuning etc was done by Ralph Friend of Excessive motorsports. Ralph knows his ****, is very friendly, basically an overall super nice guy. I highly recommend him if you are in the Pacific Northwest.
Here is his XS To4X2 FD at this year's HIN in Seattle. Can you say 600 rwhp? I knew you could...
Sorry for all the big pics 56k guys. Get into the 21st century man! Get a fast modem!

I knew that name sounded familiar...I sold Ryan the strut tower brace. He was saying that he just had his car rebuilt.
Either way...you're making me drool....I'm thinking about changing my compressor to a .70 so I can have a REAL t-04S

Thanks everyone for the compliments. It was hella fun, but I was one nervous little bitch while that thing was on the dyno. It was just ******* screaming, especially on the 461 run. At the end of that session when Ralph looks at the back end that was because the rear tires broke loose at the end of the run!!! I was very suprised by the numbers the car turned, I was hoping for 400. Brad the Three Eyed Swami (GotBoostd7) predicted the big numbers, though. Once again he proves he knows MUCH more about the FD than I do.
As for the brace it is for flex only. I actually traded one I bought with Brad due to fitment issues. I know he bought it off of the forum, but not sure who through. I am sure he would let you know, though.
Thanks again for the compliments.

What amazes me, is how soon you stopped the dyno!
That torque curve is absolutely sweet! Do you realize if you would have kept on the dyno until 8200 rpm, and assuming you maintain about 310rwtq, the power on the 1st run would have been about 485 rwhp!
Look at how high your torque peak is, and how flat. That car had more in it IMO
Impressive

How come his good friend Ralph Friend of Excessive motorsports did not put his car back on the dyno (Its not that much more wear on the Dyno)? Unless he has a lambda meter hooked up to the car for street tuning use, I can't understand how he is tuning the car (don't tell me he is doing it by the seat of his pants method). I could understand if he added more fuel just to make it a little more safe but you mentioned that he "He pulled some timing out, and a little fuel."
P.S. I noticed that Excessive motorsports has a in ground dyno, I still can't belive he did not put it back on the dyno! Thats just irresponsible as far as tuners goes!
Check out the friggen dyno I have to get on to, and my car is dropped 2" in the front and 1.5" in the back!

Well, we really don't know what Ralph did Saturday morning. We showed up around noon, and he had been working on it all morning. Maybe he did put it on the dyno, or atleast hookup the wideband. I don't know for sure. All he told us when we got there was that he pulled out some timing and fuel, and now the car goes sideways through 3rd gear
The torque brace was purcahsed from KZ1

Making Peak TQ @ 6800-6900 RPMs, that port will want to be efficient to around 8000-8200.
Look at RICE RACINGs street car. Very similar, just a more elevated TQ peak (7600rpms). He peaks out at 8500-8800 RPMs I believe. 590 BHP @ 18.85 psi.
Honestly you could probably raise the TQ peak just by using a larger exhaust housing (T04S is a 1.15 divided p-trim I believe). I think that housing is a great compromise, though. Nice numbers again.

RPM vers dynorun
I just wanted to let everybody know that the optical RPM pickup I use
could not pick up off the crank hub due to the intercooler mtg. I had to
use the powersteering pully which is a different diameter so the rpms
are 550 higher than it reads on the chart. I realize this sounds inaccurate
but when I tune from the beginning I take this into consideration on
settings. The optical pickup is far more accurate than a magnetic pickup
especially on a rotary with leading and trailing firing.
The datalogit is great!!!!!!!!!!!!!!!!!!!!!!!!!!!

Quick ?
Was this a T04S or a GT3540? I see in the post you refer to it as a T04S and the title for the videos you label it as a GT3540. Just curious. By the way nice numbers I hope I can get those kind of numbers with my GT3540.

It's a T04S.
gt3540 is the url for my website. I needed some webspace bad, couldn't decide on a name, so I just named it after the turbo that was sitting in my bedroom. Too bad I don't have the turbo anymore...
I hate you FortyOunce!

It was all just a matter of time, or the lack thereof. Please don't bad mouth Ralph, he does excellent work. He would have probably stayed all day on Saturday too if we wouldn't have had to leave.

Way to go Ryan!!!!
Great #'s, Congrates.
Now you definitely got a bug up my *** to visit Ralph to sort out my car. I know I got 50 more hp under my hood, I just can't find it
Head out to Bremerton one of these weekends & try your hand at auto-x
Check out the calendar of events at....

Ralph is realy very cautious. Infact, when we had my n/a fc on the dyno, i kept on wanting to take out more and more fuel. At one point when it was at a a/f ratio of about 14.25/1 he said no more. After pestering him enough, and telling him i would'nt hold it against him if the motor let go, he finally let me. In the end Ralph was correct as the car started falling off on power. But its nice to have a tuner that knows what he's doing and cares about his customers.
As far as the port in his engine....its realy big. He says it hits realy hard at 5k, then again at 7k, and he shifts it at 9k. Last i heard it put down 530rwhp@22psi. That would just be insane...
