@2.4

Got the mail.
I'd say you have a boost leak.
Why do you hit full boost at 4k? That seems a little high.
Would also explain the perfectly linear boost drop.

You're on a 44, right?

Man, I wish my car would spin 3rd :/

I Still get boost drop even on PCM control. I blame mine on my shitty TurboXs. last night it was about 24psi falling to 22 at redline. I hate that shit

2.4HEMI · 07-04-2009, 12:58 PM

yea im falling 4 psi from the point i hit full boost to redline and i dont hit full boost till 4k i still want to try pcm control though, i probably do have a boost leak

I think my Greddy BOV doesn't seal right either...
My spool seems fine, right around 3500, but I drop a lot.
Drop isn't linear though, it looks like a freakin valley

Kason23 · 07-04-2009, 12:59 PM

Yea you gotta a boost leak there my friend. Mine will hold till about 5500 then drop like a rock.

TmP · 07-04-2009, 01:01 PM

Goes down, comes up ... no idea.
Hope the boost box might fix this.

Kason23 · 07-04-2009, 01:10 PM

looks like a boost control problem to me. What MBC are you using again?

Mine looks ok I guess long as its running good times I dont really care.

TmP · 07-04-2009, 01:12 PM

I'm on Joe's MBC.
Like I said, have my hopes up high for the boost box.

Yours gradually drops too, not much though.
Who said that the turbo was able to hold 23 psi rock solid anyways?!
Maybe that's how it's supposed to be?

Kason23 · 07-04-2009, 01:14 PM

That it might be. But I figured since big wheel stg 3's that are externally gated are holding 25psi that we should be able to right?

TmP · 07-04-2009, 01:19 PM

One would thing...

Have you ever SEEN a 25 log?
I haven't.

Impossible until proven guilty... or something like that

Kason23 · 07-04-2009, 01:26 PM

true true lol. I just made a post in AGP's section so we will see what they say when they look at it. This most I have ever got the car to hold was 23psi in third(all the way to 6500rpms) and almost 24psi in 4th at redline. I think I will do another boost leak test today to see

TmP · 07-04-2009, 01:28 PM

Well, AGP and all the fans there are going to rip you apart as soon as your question can be somewhat mistaken for an insult...

Kason23 · 07-04-2009, 01:31 PM

yea I know how it goes lol. But like I said I dont care if it cant hold more.long as it does 120's at the track on pump im good haha. Those spark plugs are way better then my 4306's I was using

TmP · 07-04-2009, 01:34 PM

What plugs exactly?
I'm on NGK Iridiums right now.
Was hoping that they'd fix my knock, but no, not so much

Kason23 · 07-04-2009, 01:46 PM

Yea NGK Iridiums 5107 2 step colder. They seem to like the nighttime 70-80 degree weather alot
