Full Race Stock Location Turbos

[Kmorgs]

Pure Turbos has an option as well, don't know pricing but i do know they take your stock ones and modify them.

What are the weak points on these engines? Rods?

A big plus with this kit is that the factory electronic wastegate actuators are re-used.

Boost control on most other turbocharged engines that we've become familiar with uses a vacuum diaphragm and spring to open and close the wastegate. A boost control solenoid can take a frequency signal from the ECU to bleed off some of the pressure reference to the diaphragm to keep the wastegate closed for longer and build more boost pressure. These systems have a lot more nuance, but you can consider this a 10,000ft. view.

On the Raptor, you've got an electronic wastegate actuator per turbo that receives a commanded position signal from the ECU to open and close the wastegates and modulate exhaust flow through the turbo. Electronic wastegates offer super quick response, huge improvements in precision, and will hopefully be more reliable in the long term since you don't have to worry about leaking vacuum lines.

BUT, to my knowledge there does not appear to be any way to convert the signal delivered to the electronic wastegates in the factory harness to a signal that could be used by a boost control solenoid. This means that if you install turbos on your Raptor that do not use electronic wastegates, you lose the ability for the ECU to operate the wastegates. Ford boost control is super advanced and works really well in a wide range of environments, so I think you'd be hard pressed to implement an auxiliary, standalone boost control system that works anywhere near as reliably. As a calibrator, I definitely know which way that I would push a customer.

Just something to consider when selecting turbos!

Why would you not have a bracket made to keep the waste gate. That’s the plan.

Side note, why is the signal type they give off in oem form?

Yes, the stock engines are stout. On my 2014 gen 1, i have 60,000 miles of twin EFR abuse. On our 2018 there is 3000 so far. If the ignition timing is not aggressive + decent fuel used, its an absolute hoot behind the wheel for a long, long time. Typical Dyno numbers are in the low to mid 500 range for a reliable stock motor setup. the powerband is so.much.fun - the dyno chart does not do it justice. Of course big turbos are not for everyone. you need to know what youre getting into and understand proper install/tune.



Hi Sam, thanks for posting your thoughts. The electronic wastegates are a double edged sword. We agree its a fantastic tool for turbo shaft speed control - we're testing the OEM Raptor Electronic Wastegate actuator on an unlimited class Pikes Peak entry this year.

On one hand, you are correct these are quick and accurate - the built in position sensor allows for incredible visibility and provides valuable data. On the other hand it's extremely sensitive to any misalignment, does not yet allow for much higher boost levels and is a source of great confusion for most installers. Electronic actuation is new to the aftermarket, and the installation of the actuators can be challenging and time consuming. we've been working on a few solutions, but it takes time working with the big OEM suppliers.

That's why precision's turbos retain the actuators and basic oem turbo configuration, easier install but less top end capability than an EFR or GTX/G25 rotor group



correct - that is the tradeoff. lose the oem configuration, and spring pressure or external boost control is the solution. That said, it works pretty well for every other car ever - and its a BLAST to drive a big turbo raptor with pneumatic actuators

Geoff, what would be some of the higher or boost levels that these oem waste gates can handle and or be able to use? This is a hair concerning

With all the downtime, what is the status on turbo options for the Raptor Full Race?

 

[Wfo]

I am interested as well

 

[full-race geoff]

the EFR twin turbo kits continue to perform. here is a Raptor dyno chart from today - 4.2L RMB stroker with our EFR turbo kit. The dyno chart does not do this vehicle justice whatsoever.



We've made a ton of progress on the engineering side of the G-series stockish location turbo kit.. until Covid19 caused our supplier Garrett to shut down operations, and do not know when things will resume. This is our holdup. I will put a detailed post together once we are closer to production, I think it will be worth the wait

Any results on stock motor?

Any results on stock motor?

Not from us, but have seen some people on facebook

Any results on stock motor?

i have some stock motor EFR dyno charts in the 500-600hp range. but i would not feel comfortable pushing the stock rods and pistons above 700hp (maybe on E85?)

Good stuff
