Ok you win...but to be fair those who want a ride get a ride.

 

Allllll righttttttt

 

Ok Everyone so last weekend was a big weekend for the G35. On Saturday I entered my first show ever (JTuned) with Team Outcast and my G35 took 2nd place in the infiniti class. It was very exciting to place as this was my first show and I was not expecting to win anything.

BTW Congrats to 2C of Team OUTCAST for taking First Place in the Infiniti Class!!!!

But my weekend did not end there. My break in mileage has come and gone, and I will say the car has been awesome!! No major problems whatsoever. So on Sunday I decided to go to Technosquare to have the car re-tuned.

I came away very impressed with my final numbers. The car made 550WHP and ~480WTQ @ only 14 psi on 91 Octane!! Tadashi was also very impressed with the results, and he very much enjoyed his post tune test drive. The car is an absolute monster now. Pulls so hard up top it seems as though it does not want to stop. I could not be any happier with outcome, and the drive home was a blast!!

That's awesome man. I'm assuming it could be a lot higher, but Tadashi has it set for reliability more than anything?

That car is definitely a beast now.

 

Very nice. Congrats on both wins

 

EPIC thread & results Mike! Congrats. Do you plan on entering her in any other contests soon?

 

Great power but that is an odd power bump at 4600-4800 rpms with sudden drop off at 5k, but it's level after that. Did your tuner explain it?

Looks like maybe your clutch slipped momentarily (if it's not present on subsequent pulls).

 

We could have gone for more power, but honestly I felt it was enough. I think I will take the time to get adjusted to this and then maybe crank up the boost. Pretty good power IMO with only 14psi.

Thanks buddy!!

Thanks bro!! Yeah I am planning on doing a big show schedule next year with Team Outcast. Planning on switching out the wheels soon, and doing a whole visual overhall. I have not decided on which wheels yet (wanna do something different) and I am leaning towards a full Chargespeed kit. That should help set me apart from the competition.

Yeah you know thats a good catch there. I was so excited with the results I did not really analyze the graph too much. Im gonna stop by Technosquare and see what Tadashi has to say about that. Thanks buddy.

 

Actually with the Carbonetics triple plate in place, there's no way that's a clutch slip at 4700 rpm. Besides, Clutch slip wouldn't make more power in the form of a bump in the dyno graph. If anything, it'd show a momentary reduction of power transfer to the wheels. So no need to worry about that there!

What you're seeing is most likely Tadashi pulling timing and dropping wastegate duty cycles to prevent the turbos from spooling to their max potential. Remember, these GT30s are happiest ~22psi. This tune is only running at 14 psi peak on CA-91 Octane.

Mike, I'd be very curious to see what your boost graph looks like. If you could have Tadashi print that out, It'd be interesting to see what your boost levels are doing from peak to redline.

This car is making healthy power with very little effort. Each time through the mod-process that you decided to go all out vs hold back has proven to be well worth it. I think the head work that you had Portflow do has made a considerable difference overall, allowing you to have the turbos barely working to make such an abundance of power!

Congratulations again, Mike! And thank you for inviting us to be a part of the process!

 

There is a momentary reduction relative to projected torque at 5k rpms. I agree that a carbonetics triple shouldn't do that though (normally). It is an odd power spike or drop off (depending on whether you look at 4600 rpms or 5000 rpms) and I can't imagine a tuner would leave that in purposefully. Now that I take a 2nd look, I suspect there is an issue with boost control with a boost spike as the turbos spool. What kind of boost control is in place? Manual? One of the problems with using the stock ECU for control is that there is no overboost failsafe. I would ask your tuner what would happen if your boost controller malfunctions.

 

The boost controller is an HKS EVC Boost Controller.

Boost needs to build until it reaches the target level. Once it does, the time it takes the wastegates to open, generally causing a small spike. I'm not really seeing anything to be concerned about. What you're seeing is lower wdc (i.e.: bleeding boost) and possibly pulled timing. It looks like Tadashi just wanted to hold a flat, consistent torque curve to redline.

Mike, just for your own piece of mind, you may want to ask Tadashi about it. And again, I'd be very interested in seeing the boost graph. It would actually help explain a lot about the curve that rcdash is talking about.

 

Guys I appreciate the concern. I am going to go down to Technosquare and see what Tadashi says about all of this. I don't have the boost graph handy but, it holds solid...nothing crazy going on there.

 

HKS EVC - top of the line! If boost and AFR are flat line solid, then I don't get it. Probably nothing to be concerned about though I am curious to hear what Tadashi says.

With the investment you've put into this car, I would consider some kind of overboost protection. As I recall at least the HKS EVC has a warning alarm of some sort so you can let up on the throttle if it spikes.

 

How's that car running Mike?

 

The build list looks very nice, except for the Carbonetics twin disk.

The Carbonetics twin disk will be your limiting factor. It will not hold what that motor will be capable of...

XKR's Carbonetics TRIPPLE disk started slipping somewhere around 700 whp I think (it was rated for 800 hp). The twin disk probably won't even make it anywhere near that. Does anyone know what it is rated for? I'm guessing you may get to 600 whp with it, but that is just a guess.

I fried a Clutchmasters twin disk FX600 the first time I launched hard at around 550 whp with a moderate amount of clutch slip.

So, I guess what I am getting at is that you might want to look into a tripple or quad disk clutch if you want to be able to use those turbos that you have the way they were intended to be used. If you are not going to use the APS Extreme turbos to get extreme hp, you might as well use smaller turbos and enjoy the benefits of faster spool up - less turbo lag.
