You Evo owners out there with boost controlers. What PSI are you setting it at? I have a Greddy Profec B spec. I set it a 23 and DAMN! ! I heard 26 is as high is we can safely go. Any thoughts?

 

Have you installed it yet??? How easy is it to install? Please give a detailed review after you test it out. thanx!!!

 

It's installed. I will take pics tomorrow. It took about 2 hours. I didn't do the install but I watched. Pretty easy. But I'd rather keep that for the professionals.

The Profec B spec is sweet, simple, and straight to the point. Holds solid boost and doesn't take a degree to use it. I wanted something simple and effective and the Profec is it. Setting for low boost and high boost. After installing, with the unit off, I got 10psi. Mind you the ECU is no longer controling the turbo. ECU must give it the extra 9. With the unit on low boost it maxed out at 16, which is cool. High boost I got as high as 23psi. And DAMN does it pull. Sweet thing about it is turn the unit off, run 10psi, save yer turbo. Wanna eat some V6 Stangs and Camaros? Use low boost. Wanna eat some V8 Stangs and Camaros? Use high boost and hang on.

 

LoL! Steve's on the run. Already got few goodies on his Evo. Keep us updated mang!

Btw.... where did you mound your boost gauge?

 

I'll keep you guys posted for sure. I mounted the BC in the little flipdown compartment to the lower left of the wheel, sweet spot for it. I need a little velcrow to hold it shut, the unit is real light.

 

theres a flip down compartmnet left of the wheel?

thats news to me. What about your warrenty stv? are you just chucking it away?

 

Not realy chucking it, pushing it so to speak. If something busts I'll put it back to norm. I f it doesn't cost that mouch to fix, eh, what the hell, just pay for it.

 

Nobody check the stock boost with boost gauge or BC?

The graph is my guess from EVO8's ECU data.
(It's a ECU's target peak boost. )

Y-axis: Boost (bar)

refer. : 220 -> 1.2 bar (17psi)
190 -> 0.9bar (13psi)

X-axis: RPM

Some body checked it, plz let me now.

 

 

I just installed my profec b. Mounted it on top of steering colum on top of Greddy turbo timer. Not my first choice to place them there, but the harness for the turbo timer doesnt give you much options. Stacked they look cool at night. The blue lights set it off. It took about 2 hours, and looks clutch! I have the low setting @ 55% and the high around 68%. The gain is @ 13% and set gain or start boost @ 46 on low setting and 59 on high. On a hot day i wouldnt boost past 23lbs. At night with some ice water mixed with rubbing alcohol in the I.C. sprayer, it's a whole nother story. On high boost @ night I boost around 24.5, 24.9, it constantly changes, so if this is happening to you, just keeping playing with the gain the get the boost as stable as possible. But if you always boost at these boost levels, you might damage the seal in the turbo, which will make it start smoking....blah, blah,. So be good to your stock turbo, so when time comes for a new transfer case or tranny, just slap the stock turbo back on. But...I love the Profec B. It's an awsome piece of equipment at a great price. I paid $300.00 from a local shop. It was easy to install, for me anyways.

 

stock turbo you guys are running 23lbs? what octane?

 

19.5-20lbs (im running 141Kpa)

 

Damn, I forgot about this thread. Just popped up in my email.

A lot has changed since then. I've got much more done to the Evo. Needless to say my warranty has been long gone for a while. It's funny to see what I posted back then. hehe
