ya that shows the turbos built exceptionally well to withstand that kind of abuse. FP makes great products.

have you driven this car yourself on the street? im sure it feels great. its such a fun combination.

 

No I havent drove it at those settings and I will soon though! I agree with you on the FP turbos!

 

This is like a 5 psi fluctuation within 500rpm, it's not the smoothing. And mustang software allows you to select a smoothing value (filter) for any input, including no filter at all..

 

When you have a car you can do it on plot Emap and then tell me its pretty amazing.

The backpressure on that little turbo is probably outstanding. 1:1 no mas.

Seriously?

It's not smooth because it's not smooth. The boost dips and peaks are almost +/- 5 psi and you can even see it in the power curve of the car on the same plot.

You can find smooth boost plots on other Dynojet plots all over the place, in the thousands.

I'm bowing out of this now because you are blinded by your own self righteousness.

 

yea sorry dude but you should just retune it with a 3port,I could surf that boost graph!

 

It's just the EVC making it wavy like that, I actually have one so I can give input on it. What is the Speed Pulse set at? You try it at 2 from default 4 and is it still wavy? What is offset/correction coefficient set at? It's only supposed to be good to 36psi so I'm curious if you chose to try and go beyond that (to prove it can) and if your using a boost offset map (FUN3 or FUN5)?

 

Fun 3 and just like I said earlier, it only has 5 rpms points to control. But my boost sensor on my dyno does do this a lot with manual boost controllers.

Here is some graphs of other boost curves.

I think the Boost sensor is not reading as well as it should.

 

I got nothin then (other than trying new map sensor on the dyno), hopefully the other dyno operators can chime in.

 

Cool it holds that much boost, but holding boost doesn't mean power at all. Remember its a restriction...so less boost up top just means your motor flows more air. I know most people know this but if anything this could just mean the motor has lots and lots of restrictions.

 

I agree, but we just thought it was really weird it held that much after fixing a couple of boost leaks.

 

Very true that boost leaks affect it big time. Honestly I am sure most of us have at least one small leak. When you are going 30psi+ its tough to not have one or two.

 

Very true!

 

Beat me too it... I'm guessing they are A cup tit retainers. I doubt that B's or C's would clear the valve cover. :-)

 

Is retention a problem?
