His runs more than mine but the boost taper is more intense.

 

Haha until he breaks down and dumps the black for something bigger. 10 bucks says before the end of next summer.

 

 

damn his falls off hard! why is that? i did a guy on a black and 2.0 and he had 14 at 6500.

im curious why mikeys car falls off like it does tho? mine holds 33-34 uptop pretty easily. imagine if you could get his car to hold more uptop. thats a 700whp car easy.

 

Cause he has a 2.4l

 

short answer-

VE. Head + cams + intake.

longer answer-

Boost is just backpressure in the intake manifold and is irrelevant. We are only worried about the CFM the turbo can output vs what the engine can use. 33psi in the intake at 8000 (on a large motor) on this turbo means the engine isnt breathing well enough to use the CFM that is there in my experience. Luke made the same power with roughly the same boost curve on his 2.0L, 41 peak falling to 34 out the top. Now reduces those numbers vs displacement and the curve is pretty much the same which means its using the same amount of air to make the same amount of power. Mikey's might be falling off more up top overall since the bigger motor is expelling more exhaust mass and is forced into a small housing. VE works both ways, it can help overall but limit faster depending on whats happening in the turbine.

 

so if you actually tried to run say 8psi higher boost into his engine at the higher rpm's you're saying it would choke out on it because it doesnt want that much? i thought it would just gain more power, but i wasnt really thinking of the limitations of the engine either. so it would spit it back out and surge the bov and turbo basically?

 

Well not quite that intense, but head pressure is head pressure. Its working counter to the turbos ability to spin, shaft speed drops and so does boost in extreme cases. We see this on the turbo quads which are as backpressure sensitive as rotaries.

 

turbo quads.. i think i seen your youtube videos of those. they are nuts.

I like that 7* ramp from 4800 to 5800 and again from 5800 to 6800 Aaron.

 

It's odd how that goes. I blame some of it on logger speed and length of pull. I mean I cant deny how the curve is but it definitely looks like it ramps up extremely wicked according to the log. Mikey's car has a V7 map and is interpolated really well, thats the really weird part.

 

Off topic kinda...

So this is probably a really basic question and I just don't know where to look, but how do you guys tune load that high? With my setup I'm hitting loads in the high 300s, beyond what is listed in the ecu, so I'm not sure what to do to tune those higher loads.

I'm not even sure why I'm hitting that much load, my car according to the virtual dyno isn't making that much power...

 

What's wrong with extremely wicked?

But yes, agreed, I'm sure that at that power level, 3rd and 4th go by so fast, that timing curve gets exponentially "wicked".

 

next time you need something like this go to google.com and type in your question followed by evom after it and it will categorize every thread on the forum for you with your questions already answered.

so maybe your maf needs rescaled or the screen is no longer in it etc. can make it ready higher then normal.
