So i had my car tuned by Steve Kan about a month ago with some seriously bad intake temps on a dyno dynamics dyno. My intake temps got as high as 65 degrees c. I properly ducted it and got to a consistent 42 degrees c. and re-dynoed the car at Drift Office in Auburn. Today it made 379whp. Which is exactly 1hp away from what i was hoping to make. Thanks Bob for an awesome experience on a very nice Brand New Dyno! Very nice equipment there. Here is the nice new chart. 4th gear by the way if it matters to anyone. Enjoy.

Hey looks great. I'm going that route someday. JUdging by the torque, acceleration from 3k on up looks pretty scary Do you have the dyno operator's runfiles? I would like to see them.

The boost curve looks rather bumpy, although the torque seems to be pretty steady above 5k... and A/F? Almost looks a little lean from the graph above. What was your own WB02 telling you A/F wise?

EDIT: Would you mind spillling more details on the tune... gas you used, timing under boost? What EMS? Thanks

That is the worst boost curve I ever seen. What gives?

I was going to say the samething. Whats weird is you dont see much variation in the HP which is common when the boost is all over the place.

The problem here is, i'm running my wastegate with a 7lb spring at 15psi, so the boost is a little strange to say the least. I have a new spring on the way which should really help smooth things out. That will allow me to properly tune my boost controller. So yeah your right. This is only really the first incarnation of this massive project. Lots of little bugs to iron out. Lots of fun so far and lots more to come i'm sure. And yeah you are right this car is completely insane from 3k and up. Not even slightly disappointed with any of my choices here.

92 octane pump gas, apexi power fc, the tune was done by Steve Kan with some boost oscillation which is seen in this chart. Oh and i'm pretty sure that its not lean at all. Probably the contrary. It looks to me to be at a pretty consistent 11 or 12.1 afr which my friend is quite rich.

likely a boost controller with the gain set too high, classic overshoot symptoms

Congrats!
Looks like the power was still going up at 7k rpm.
There's a huge difference in power and tuning between 11 and 12:1 AFR's. That's not consistent afr's. Also 12.1 afr is not considered rich and is quite lean by rotary standards especially for the fuel being used to tune. Lean do give nice #'s on the dyno if that's important to you.

Sad thing is that it most the time is the most important thing to many people... Who cares about the 2-20k in engine work and the fact that I paid good money for my mack daddy fuel system.....I just want a queen

Nice numbers...

which GT35R are you running : T3 or T4...Rx7store or an A-spec. Also like to know if your motor is ported or still stck?

It is a t3 with a .82 exhaust side, and an anti surge housing. Mild street port. I made the kit. The manifold is made by clr motorsports. Pretty nice stuff. Kick *** powerband. I have no idea why people bother with divided t4 1.06 stuff when they come from garrett capable of this.

Not sure what you mean?
Capable of what?

My brother's car run's a T3 1.06 and he's making 450hp+ at less boost then you run.

I feel .82 is too small..

crispeed

Your .82 housing might be limiting peformance base on your setup like Enzo said above. You're basically makng around the same power as a FD with stock turbos for the boost level.
How much boost were you actually running? I said this before but it looks like the power was still increasing at 7k rpm so why didn't you take it higher?

That's one good reason right there. It's all about what your after.
