I don't know yet.. I have to put on my boost gauge....

to be continued....

 

Hardcore Tapering...... (Update) Map Verified

28 PSI @ 4000 RPM - 20.5 @ 7000 RPM

Increase boost..... and

30 PSI @ 4000 RPM - 20.5 @ 7000 RPM

I am going to guess I have a major boost leak... Going to do some tests soon .

I should be able to hold more than that..... since people like ElectricEvoIX spikes less and holds more . Grr. Probably explains my low traps at the track .

 

After a little more reading I see we can adjust the stock WGA arm and hold some more boost? Any of you guys holding high boost, have to do this? (MBC guys)

 

Warrtalon you're a ****tard so STFU already.

 

STOCK - 20Lbs

 

hallman mbc ... 22-ish psi and holds.. maybe drops .5 psi

 

34 pounds at 8k

 

in 85 degree temps at sea level i'm boosting 17psi tapering to about 12.....got a leak somewhere....need to switch to T-bolts and I am 100% stock

 

I hit 23 and it never tapers. (I use a hallman MBC)

 

I hit 22-23 psi peak and tapers to 19 (controlled by Ecuflash). Mods are HKS 264 cams, K&N drop-in, espelir dp, invidia 3"exhaust, megan resonated test-pipe, stock 03 turbo with 9.8 hotside, Walbro 255.

 

mine spikes to 25-26psi and tapers to 20psi with hallman pro rx

 

Im in your boat, higher elevation, does not matter what I spike to holds 19.7 at 7000, 18.5 at 7500, but nice 25 through the middle. But always seems to be the same at high rpm no matter what the peak boost. I travel between 3100-4200 feet. I have the forge as well. My friends stock IX with a flash hits 19 tapering to 16, he would taper to 14 before the flash. He was excited the other morning with the cold air held 17 psi.

 

using defi mine spikes at 23 holds at 22

 

Greddy EBC, 20g-IX-5 (FP EvoGreen) on pump gas (91 oct)

 

Profec B-spec II, bolt-on car (intake/tbe/fp), tuned for 110 oct: 29 peak, 26 hold. Yeah that's high, I know
