More on Roush Yates 3.5 Ecoboost

[racingmason23]

So as someone previously posted Ford Racing has gotten Ganassi to switch from BMW to Ford Ecoboost for the new sportscar series.  The rules last year were limited to 500ish hp and Grand Am would adjust the rev limit if one manufacture had to much power, they took 500 rpm away from Ford 2 years ago.  Anyways like 4DR I have been bugging Roush Yates about the aftermarket potential, and a few questions on their fuel system but they have not returned any emails yet.  I did provide them with a link to the forum, and maybe they will stop by I can also see how they would want to keep their data in house. Here are some recent videos on the 3.5 they built for the DP.  It carries 70% crossover from the SHO. Maybe someone can't get ahold of Jamie Allison from Ford Racing!

I've sent emails, facebook, linkedin all ignored. Ford Racing on facebook said they can't talk to me. One of the major reasons why I gave up on the platform for a little bit, I need a rest from innovating and to follow some other people's lead for awhile.

I wonder what the reasoning is for not talking to a loyal supporter of their product?

What a crappy way to conduct business.

Most likely they have some exclusivity contracts with the various racing teams. Racing is BIG business and you can rest assured that there are some iron clad NDA's inplace on both sides of the deals.

Watch the third video and you can see how Rousch Yates solved the HPFP problem.  There are TWO HPFP's, one on each head.

Very interesting. Can we pull this off on our cars?

 

[FoMoCoSHO]

Stock block and heads....that means our cars are capable of some serious power without blowing up.

Maybe FRPP will finally give us some love now.

LOL, probably not.

On paper? Probably.  At minimum there would need to be a new cam (need the extra lobe to drive the second HPFP), new valve cover, possibly customer machining/fab on the head (so the HPFP can be mounted), new fuel line plumbing (both Low pressure and high pressure lines), and probably the most importantly, a way to control dual HPFP's.  It might be as simple as tying the sensor wiring of the new HPFP into the original wiring and changing fueling tables in the stock ECU to trick it into thinking that the single pump is flowing double, or it might take a custom stand alone fuel controller.  That doesn't even address if there is physical room in the transverse platform.

Bottom lne, it looks like at minimum a $3000+ upgrade and probably much for for the first brave sole that tries to go through all of this assuming that Roush Yates isn't going to have their own "kit".

Many people take the "stock block" statement the wrong way.  I'm as close to 100% as you could be in saying that "stock block" means the bare block, not the stock crank, rods, pistons.  Stock block, is also going to be the F150 block, which IS different that the transverse 3.5 Ecoboost.  the F150 block has extra main bolts and some other structural differences that make it stronger

 

[4DRHTRD]

OK so I make more power than their motor on a COMPLETELY stock block, pistons, rods, heads etc. Those guys have forged rods and pistons with stock crank along with porting/polishing of the head.
I've looked into a second HPFP, the low pressure lines/in tank fuel pumps I have handled. The valve cover will be $10K to $20K for me to get castings made to make the cover. The cam is where I ran into a brick wall and was hoping ford could tell me where to go to buy one.
The F150 and Transverse block are both 6 bolt mains, just FYI. No difference in the bottom end. They used a SHO block for their motors, I bought one of their take off manifolds for my aux injector manifold.

I have some more pictures as well.  The intake manifold intrigues me as they are using 2 throttle bodies and each turbo feeds a spilt intake. Early syncs showed it as steel and now it appears to be a plastic polymer.  The turbos each have the own air water cooler. Ford has put a lot into this ecoboost platform.

4 Dr have you tried contacting Ford Racing? They have been going with relevancy as the reason to race an ecoboost so maybe with some well worded discussions we can get some of the engineering to trickle down.

I have a feeling if the 5.5 l vs "voodoo" ecoboost for the go 50 replacement is true it will open even more doors for us. Ford can't unveil the new Mustang soon enough.

I don't know if you guys can share the video of my Flex putting down 600HP on a stock Ecoboost V6 or not but it would be great if you could show the strength of this motor. We've just upgraded fuel system and bigger turbos and new downpipes. Pretty simple mods. Thanks! Mike

I know you guys are super super busy but even a simple nice job or, sorry we can't share your video would be nice after I've sent you guys a couple of messages. I'm working my tail off trying to prove the Ecoboost platform is a valid strong engine and making great gains on my own. It would be awesome if Ford recognized it publicly or even better would share some info on how I can get some more flow out of the heads etc. So far all of my work has been done by myself and a few others I've convinced into making parts for me. Anyhow great job on the Ecoboost V6 race motor, I look forward to seeing what the stock block can handle as I am also pushing the platform as far as it can go. Also can you confirm or deny the following in your Ecoboost race motor: Forged rods and pistons Modified valve train and head work

I'd love to chat with whoever did the fueling, I've had to add auxiliary injectors and controller. To have an upgraded direct injection pump and injectors available for this platform would be AMAZING and allow us to tune within the factory ECU instead of with factory ECU + piggyback for the aux fuel injectors.

Mike, we saw your video on our wall and the power gains you have achieved are impressive. We can forward your note to one of engineers for answers. Thanks again for sharing the video.

We spoke with our engineers and without giving away too many trade secrets, here is what we were told. The EcoBoost Race engine has been designed and calibrated to withstand the continuous high RPM demands associated with endurance racing. The EcoBoost race engine uses a stock block, forged rods and pistons in conjunction with a slightly modified cam. The heads are stock castings with slight modifications to enable improved flow to accommodate the larger turbos. Due to series requirements, the VCT is locked out. Thanks again for your post and good luck with your high horsepower Flex!

Can I ask them one more question please, I need to understand if they modified the fuel system please.

Thank you very very much for your response. I'm literally all by myself at the power levels and modifications I'm at and any guidance is super helpful!

Mike, yes. Fuel delivery needed to be enhanced to feed the beast.

is the car still direct injected if so did they upgrade the factory fuel pump and injectors

I need to find a source to be able to upgrade my high pressure fuel pump and injectors

Yes, still direct injected with a bigger fuel pump. Good luck!

Typical response. I'm sure things will trickle down soon.
