Using the FBM Stage 1 Turbo Upgrade and FBM 850hp Intercooler Full Blown were able to extract 501whp and 476 ft lbs tuned on Cobb Tuning.
The Ford Focus RS Ecoboost uses direct injection for its fueling. FBM quickly found that the DI system needed support in order to meet their fueling demand.
Their solution was a secondary port injector system that adds (4) additional injectors on its own manifold/spacer and fuel rail. This allowed them to run the maximum ethanol content available at the pump (E83) to suppress detonation.
Although the factory clutch seemed to be doing its job, it was actually slipping worse after each dyno pull above 450ft lbs. Full Blown contacted their friends at Clutchmasters and came up with a solution to put down the power. After installing the clutch, they went back on the dyno and laid down the first 500hp pull.
I wonder why you wouldn’t just install a fuel pressure regulator and uprated fuel pump. Adding more injectors and rails seems OTT for this jump, and I’d do it using a larger turbo and forged internals instead of putting race fuel in the car.
Did they send a graph with the RPM at the bottom of is that cut off deliberately? Seems a bit odd to remove that unless it’s laggy and they don’t want anyone to see.
So hang on, now internals have to be changed? Where does it mention that above!?
Has anything else been left out?
I see several comments on the FB page asking why extra injectors and so on.
For me this has been a headline grabbing exercise that hasn’t really delivered on expectations.
If I’m spending that sort of cash to forge the engine and so on I’d be looking to an established UK company like Mountune or Pumaspeed.
It will go BANG. The work these guys are doing is highly impressive, but they are doing it for one reason and one only – to test what self destructs at elevated power and torque – to then replace it with better components. Headlines = attention = publicity = sales.
Stronger internals are already being advertised via several tuners and this company has not recommended or suggested anything other than they have reached a number on a graph
They have said that the clutch was struggling and I’d be stunned if it wasn’t (even though it’s considered strong) and TBH if you’re going to add another 50% power to any forced induction car then surely internals should be a consideration if boost levels are tripled
people are fitting the forged internals that are looking at the early to mid 4’s in order to be on the safe side
there is a really safe alternative though……leave the car standard and stop worrying
I suspect dyno’d in 2wd mode therefore no stress on the rdu at all. Let’s see how this works out. If that tune, with limited hardware change is reliable and maintains a decent degree of driveability, then I’ll be impressed…
