Re: My Ford Flex build from the beginning.

Nice Pix...  really shows the complexity of the cams.  Can you tell from viewing if they have variable valve timing?

Yes, the big chains on the round deal on the intake cam VVT. The other chains closer to the inside of the motor are the timing chains.

 

[4DRHTRD]

Intake is installed, car runs again just working on the fuel lines and the auxillary injector controller.

 

[4DRHTRD]

Intake is done! I'll post up some better pictures and info as we move through the tuning process!
Ford Flex auxiliary fuel system walk through

Any updates on this build?

 

[4DRHTRD]

Let' see, since then the following has been done:
Upgraded stock turbos with billet compress wheels installed
Dual in tank fuel pump installed, removed auxiliary fuel pump and fuel cell under the hood.
Fought boost leaks for 2 months....
Had new hard pipes prototyped, on the way home the car held a solid 23 PSI across the board in a 4th gear pull but at 9.2 AFR, I'll be tuning fuel tonight.
I need to dial in the aux fuel controller tune and then dyno test the current setup.
My new turbos ship out tomorrow or Monday and will be installed next week hopefully, so I can go back and re-dyno with the super duperdy cool turbos installed.
Going to be an exciting couple of weeks!
Once new turbos are installed I'll be heading to the local track to see what she'll put down and then possibly out to California for some runs in good air.

It will be tough to see what the gains are on just the upgraded turbos since you have done so many additional mods, but what would be the expectations for gains of going to upgraded turbos on a Stage 4+ build (CAI,downpipes, exhaust and tune)?

 

[4DRHTRD]

If you really consider my mods that's all I've done besides augmenting the stock fuel system.
My overview of mods:
Cold Air intake
Hot pipes (only to stop boost leaks) no HP gains
2.5" downpipes with cutout and stock exhaust
Upgraded stock turbos with stock size billet compressor wheels
Aux fuel system and upgraded in tank fuel pumps, no HP gains
E85 - this is the biggest HP gain I've added besides the turbo upgrade.
Nitrous is either on or off and mostly off

Latest update!
Installed turbo upgrade from ATP Turbo - new center section turbos.
Car put down 600WHP/642WTQ

More updates as they occur!

Slick!  I'm jealous

 

[askoncemore]

So where are the time slips with the 600hp?

 

[4DRHTRD]

Went 12.4@109 going into limp home mode at around 1200' - that's why so low of a MPH. 5800' DA btw, HORRIBLE air.

 

[askoncemore]

I look forward to seeing the numbers with better air.

What was the issue going into limp mode?

 

[4DRHTRD]

The Flex is LONG gone, put back to stock and traded for a CTS-V.

 

[QuickSilver]

Just your average 10 second CTS-V

[askoncemore]

They're all on Jacob's SHO pretty much has them all on his car except a few parts sold to others. Car was traded back in Nov 2013.
