Dynomotive hit 600 BHP at the wheels with 2024 Ranger Raptor (w/ ported heads)!

[Bonus Oz]

I sense we are going to need a tuning and mods section :
Dynomotive are developing a bolt on kit but are running a test unit that has hit 600bhp at the wheels on the dyno .


Future post : first Raptor to hit 1000bhp.

Yeah, but this isnt full bolt on. They are porting the heads and such. Id like to see what just pure bolt ons will do; intercooler, cat-back exhaust, intake, tune etc..

I need to go through the videos, but I’m also digging the tires they have mounted. Must be a level kit too.

Fabulous Fabrication has hypothesized that the RR runs a closed loop fuel map, and makes adjustments to maintain its settings. They also showed that a cat-back exhaust does nothing other than add sound because Baja mode already makes the stock system essentially free-flow. Similarly, the intake did nothing but make more noise.

Unless the RR runs MAP fueling, that will adjust automatically to less restrictions and more air, we’ll have to wait for a tune to beat any performance fruit.

Sorry, I meant "turbo"back exhaust. The videos Ive seen of those are showing 30hp gains. I really wonder what the Ford tune will offer when they release it. Ive never heard of a factory tune before or researched them to see if they were tamed down to preserve warranty or balls out to give the customer what they want.

I am sure it will be a conservative bump, because no OEM wants to dealer with a customer-induced headache. I'd wager the tune would primarily up the boost a few PSI, to remain within the turbo's thresholds. Similar to when BMW presented the differences btw the standard M4 and M4 Comp...mostly fuel mapping with mild adjustments to boost pressure. Mechanically there are no engine differences between the M4 & M4 comp...it's most tuning & exhaust.

How's the transmission holding up?

Episode prior to the above shows results prior to porting heads etc.
Shows results from the bolt on kit available .


Transmission - larger pan was fitted to drop the temps 20 degrees but rest is stock

The RR indeed runs closed loop under WOT and most driving conditions. The two AFR sensors, one for each bank are also wideband sensors.
I would hypothesise that it is running a throttle mass flow (TMF) setup with the independent pre-throttle boost pressure (TCBP) sensor, post throttle MAP sensor, manifold temperature sensor and the known throttle body size. This would be awesome as it is a setup used to good effect in a few high end aftermarket sports DBW ECUs.

Larger pan makes sense. What is engine oil capacity?

After racing with SCCA for 32 years, I can assure that flowing heads (not just porting) is where power is generated. However, that also needs better flowing intake and exhaust to make it work and it is important to have those tuned together. I never worked with a turbo but I am sure all of that is still true. Kind of similar to bumping compression ratio.

Flowing the Raptor head will be a challenge as there not the conventional design . These Ecoboost heads have the exhaust manifold built into the head casting with no access .
The Turbos bolt straight to the heads via a single port outlet to each bank.
So what has gone on in the past and what was important is now not so much and a differant way of thinking is needed.
The head design is very good and flow is great from what I have seen apart from the cold start lip to the exhaust valve bowl not much can be improved.
This cold start lip could be removed with a dremel if you were game enough as any further engineering would be pointless to these heads.
Future tuning attention will be around boost pressure levels , fueling and keeping that intercooler cool i suspect.
Ive been tuning V6 twin turbo engines since the 90s in the form of the 6G72 Mitsubishi GTO /3000GT and they became quite easy to pop to 600bhp .
2 x bigger turbos , 6 x 1000cc injectors , fuel controller and a boost controller .
Issues using a stock engine was detonation , Main bearings would let go , Rods would bend and it would then try to push the heads off.
All of these issues wont show in the Raptor engine as we are starting with better basics and I will be the first to say one day someone will get 1000bhp from the little Raptor engine.

 

[gdub]

You are 100% right. I have not dealt with turbo charged engines, only N/A engines. I forgot the turbo not only increase compression it also pushes air through the ports. Sure improving flow of the ports can help but improving the turbos will have more effect on power. Of course, getting the exhaust gasses out efficiently is important too.

check my dyno results post, it went from 355 whp stock to 420 whp with the mods. that is close to 500 hp at the crank
