Whats a stock 06 MR supposed to boost at?


What are flashed ECU's capable of pushing stock turbos to?


And lastly, how accurate is the OEM boost gauge in these MR's?

 

3500 rpm is max boost at 19psi, Tapers down from there

 

06 MRs boost to 20.3 psi and taper down
flashed ECUs dont control boost unless WORKS does it for you...
get a TBE and that will net you a ballpark or around 300awhps and then flash it to get around 350ish

 

Whats the reason for the taper down with the higher RPMs?

 

taper is mitsubishis way of not letting you blow up the stock motor
also get a MBC or EBC to get rid of that taper

 

Your going to taper no matter what even with the MBC in place since the stock turbo just can't flow that well high rpm's.

 

well, this thing has stock exhaust, a flashed ECU, and its burying the needle past 1.5 bar, so im not sure what to think at this point.

the person I bought the car off said it was flashed for the stock exhaust, but its hard to trust anybody these days.

 

I see 19-20.5psi depending on outside temp.

 

1.5 bar is 21.75 psi i beleive.

 

Maybe get a better gauge that could read a bit higher. It's kinda dangerous running a gauge that only reads to your max boost lvl. You don't know if your boost is spiking or not.

 

555R, please, do not answer these newbie questions with random stuff that isn't true.

1) Stock boost on 05/06s is 20.3psi peak @ 3500rpm tapering to 17psi by 6500rpm.

2) The taper is going to happen no matter what on the stock turbo unless you only run 16-17psi all the time. This is because the turbo is not capable of keeping up with the flow of the head when it gets to high rpms on high boost (as RNM alluded to).

3) No, an MBC won't REMOVE taper, but it will LESSEN it.

4) No, Works isn't the only flash that controls boost. In fact, there's doesn't raise boost at all, nor does anyone else's, which is why they send a special boost hose that regulates the boost differently than the stock hoses. Any flasher can do this, and some do it all the time (e.g. Vishnu).

5) He won't randomly get 300whp with a TBE then 350whp with a flash. He needs the proper combo of mods, and it depends on the dyno, the altitude, the climate, the octane, the correction factor, etc etc. Plus, that doesn't even answer his question. He asked, "What are flashed ECU's capable of pushing stock turbos to?" The answer is "around 400whp," but the real answer is that it's not the flash that determines how much power can be made - it's the turbo and its supporting mods regardless of the tuning tool.

6) The stock gauge is fine, but it maxes at 21.75psi, which is usually not enough.

 

Actualy the Taper is Calculated and by the Ecu and is there to keep you from Blowing the Turbocharger. The more RPMs the More Air required the more Air required the faster the turbo has to spin to maintain boost. So therefore at 6500 RPMs you need hypatheticly 180,000 rpms of the turbocharger to maintain 19psi. Instead of 150,000 t rpms that you would need for 19psi at 3500 rpms. So lets say the turbo charger can safely spin at 150,000 rpms there for it cannot mainttain the required boost at high rpms, but the unit will try. Instead of it trying Mitsu put in a Calculated taper to keep you from Blowing the turbo. But I don't know of anyone who has blow the turbo by lessning or eliminating the taper, or rasing the boost reasonably.

 

400hp at what boost level?

Im worried that with this stock exhaust and cat in place, this turbo is boosting to hard. To much backpressure cant be a good thing. Anyone ever deal with KTR performance in Ayer, Mass?

 

with meth around 28psi

 

well i answered based on my own experience on my 06MR

a TBE alone got me 297whp on a dynojet on a africa hot day (iat's were and or over 100degrees)
it seems the local tuners stated the my hp figures were on par for all the other IXs that were dynoed, hence i stated ballpark

my Greddy EBC hits 23.8 psi with minimal taper, i dont have a datalog on how much , thats another story ( ok u got me on that since i wrote it wrong)but i did state it hits 20.3 and tapers

apparently so i misunderstand how the Works flash controls the boost...and i decided not to go with a mail in since a few tuners are nearby anyway...

i never said anything about the stock gauge

so i am not entirely wrong...nuff said and i stand corrected
