see Kane can vouch to that as he was witnessed it himself. Man it sucks that my motor jacked up as I wanted to show off what a badass turbo it is. But maybe one day I will get off my *** and have it fixed. Kane when do you come back? I will have it done for sure when you get back and have you tune it again haha

I will be back in March of 2011.

My pleasure man, that was a fun two days - next time I am going to stay longer and do the mechanical check first before we go to dyno.

I am in Texas now. So I hope you don't get tired too much of the hot weather!

But yes definitely get the mechanical things squared away..

Canada doesnt have any emmissions standards for aftermarket either, well not enforced anyway... I meant just so they could continue production of the 2jz-gte....... Anyway a BC is not on my intial purchase list... pretty amazing what a tune to it can up the BNR to though. Do you think your kit is more of a rare thing seeing numbers like that or have people just not figured out how to tune for the BNR completely yet? Kind of mixed answers of people sayin it can or cannot hold higher boost till redline.

Getting a lot of power out of any FI car is no walk in the park . Lots of issues always arise and if you are relying on other people with limited time it becomes even more difficult .
I think this is why we don't see the results we expect for most of the FI cars out there .

MM,

I have no reason to lie about how much psi I was able to get or not get. I had a HUGE boost leak, and I was still able to achieve my target boost goal of 13psi with hold 11-12psi to redline.

Kane even said in his above post "and it was holding it with a pretty big boost leak."

Oh well I guess Kane and I have to get our eyes checked.

I have flowed damn near 400 g/s with the BNR turbo.

It seems as if I have been the only one that has not run into any problems with achieving my desired boost target whether it be 9psi or 13psi....

^^^

I don't think that was an attack as much as it was an observation that a steady 7psi isn't that remarkable. Plenty of people can push 6-10 psi fine (my personal target) without problems (and I would also consider a boost leak a problem). Your not on the cutting edge here, just as I am not; so lets not crap this guys thread out.

Who said you are lying? The dyno you posted up shows 6/7 PSI across the board.
Its right there on the sheet.

That is what the GReddy does easily.

I guess I shoulda looked at the image, that was before I flew up there and tuned it along with the BC.

The tune on the car when I walked away from it was 11-12 to redline, and it did have a pretty huge boost leak...almost 100g/sec worth actually.

I think more people are having problems tuning their BC, I've had two that had problems bad enough to warrant a phone call to me due to low boost, one GT3071 and one BNR. Both issues ended up being the BC mostly.

On the two upgraded GReddy TCs that I've seen, blocking the wastegate signal completely still didn't produce full boost after 7200 RPM.

By comparison, it only take about 20% added DC to get increasing boost on my car.
So, something is going on there.

Wow yeah, that is interesting.

If memory serves, it was between 30-35% Duty Cycle to get it to 10 PSI...

That all depends on the actuator diameter, preload and signal source.

Yeah, but unless something happened that I am unaware of, JCabs was all stock greddy.

I hate my boost controller.......i feel like i can never get it right lol. I have the E-01 and i feel like no matter what i do i cant get near my target. I want 8-9 psi....Ive fiddled and diddled but i cant get it dialed in.... Can you approximate Hp off of g/s?

Probably not the fault of the boost controller - more likely the actuator as MM alluded to above .

You can , but it's only going to be reliable if you have a base run on a dyno to compare against .

^ i guess im crap out of luck lol for the approximate but for argument sake what is the calculation?. Hmm the actuator is the one that comes with the 3071R kit by MM. I think i would blame myself for the boost controller lol i feel like a monkey when im dialing it in i grunt and throw tantrums.

/\ very rough guide is whatever g/s you have is your flywheel hp so take 40ish hp off that for whp . But several people here have g/s numbers that don't follow that example so like i said - dyno for a baseline first .
Most people with the MM turbo/actuator combo manage to get 9-10psi to redline without issue but it does start blowing open the WG at that level .
