If that was the case, I would have posted exactly that. The unexpected twist is a good thing! :P

Re: GheyrodX - bigger, fatter, gheyer!
 

LOL that was my first thought sadly.

Re: GheyrodX - bigger, fatter, gheyer!
 

Dun dun dun indeed! LOL

First I'll start with the twist: I'm out of fuel pump! This isn't supposed to happen on a pump gas stock turbo X, I must really be flowing some air ;) My tuner says the car definitely has more in it so once the new pump is installed the tune will be further tweaked.

Prior tune = 342whp/360wtq
Baseline = 345whp/359wtq
+ PPI extreme ported exhaust manifold
+ Mil.Spec ported IM
+ Mil.Spec ported TB
+ MAP phenolic IM gasket
New tune = 360whp/378wtq

That's +18whp/+18wtq from my previous tune plus gains, including quicker spool, throughout the entire powerband! Damn impressive for stock turbo/pump gas on a Mustang Dyno especially considering the car has more in it yet. For comparison sake, my IX (w/cams, etc.) put down 360whp/369wtq on this dyno.

I am beyond excited to get a new fuel pump in the car and get back for more tuning!

^DUN DUN DUN!!!!

Re: GheyrodX - bigger, fatter, gheyer!
 

Impressive Kracka,

That is some awesome power gains, what are the predictions with a new pump? How much is left on the table?

Re: GheyrodX - bigger, fatter, gheyer!
 

Tough to say, but even if they're minimal and only add a bit extra margin for safety I'll be very happy. If I hit 380wtq I'll be thrilled, but that may or may not happen since it's not down low where the car is out of fuel. I'd say probably at least a few more whp but we'll shall see...today exceeded my expectations, we'll see what happens next time :)

Re: GheyrodX - bigger, fatter, gheyer!
 

Awesome gains chip!

Re: GheyrodX - bigger, fatter, gheyer!
 

Nice! You just made a FQ-360 on stock turbo. Could never understand why Ralliart UK needed to swap turbos on any of the FQ series ( VIII, IX, X) to get those numbers you just achieved.

Re: GheyrodX - bigger, fatter, gheyer!
 

Kick ass man! Lets see some graphs! maybe an overlay with gheyrod IX before she blew?

Re: GheyrodX - bigger, fatter, gheyer!
 

As soon as Cobb has them up I will post!

Re: GheyrodX - bigger, fatter, gheyer!
 

Good stuff man! Those are some great gains. Do you think the elevation change between MN and TX made a difference?

Re: GheyrodX - bigger, fatter, gheyer!
 

Doubt it, the difference is what, maybe 500 feet or less?

Re: GheyrodX - bigger, fatter, gheyer!
 

Shitty cell phone pic of my chart, but it will have to do until Cobb gets their online database updated.

I know it's tough to read, but you can get the general idea of the gains, slightly quicker spool, and relatively close boost curve. The curves will be further smoothed once the new fuel pump is in, but there was no point finalizing the tune last night when it's all just going to need adjusting.

Re: GheyrodX - bigger, fatter, gheyer!
 

Looking good! whens the turbo coming?

Re: GheyrodX - bigger, fatter, gheyer!
 

With these kind of results seen on the stock turbo it will be a long time, if ever :) I want to make sure the car stays nice and reliable for DD street use and hopefully retain the stock clutch for a while yet.

With a new fuel pump though I'll only be injectors away from being able to support something larger.

Re: GheyrodX - bigger, fatter, gheyer!
 

Do you still have stock injectors? Based on my car, it was never too obvious which was the problem.

Re: GheyrodX - bigger, fatter, gheyer!
 

Yup, stock injectors.

Re: GheyrodX - bigger, fatter, gheyer!
 

Nice powa!

Re: GheyrodX - bigger, fatter, gheyer!
 

That is quite impressive.

Re: GheyrodX - bigger, fatter, gheyer!
 

Awesome!
