Great stuff!
Not to wet blanket any of this - I think it's helpful to mention this however...330 brake HP is equivalent to around 280 wheel HP. Keep that in mind so it's an apples to apples comparison if you're contrasting this option with one of the Garrett turbos/MRX/Pumaspeed products. Dyno chart/video "A" might say "330HP" but it's bhp while chart/video "B" might say "300HP" but it's whp which is actually more than 330bhp. Can be misleading to the unaware.
I compared this to my dyno chart from my X47 and torque comes on almost identically. I imagine it's a similar driving experience and power with the same fuel mix is probably comparable. Very nice option for sure! I look forward to more results.
Does anyone know what target boost is for these on various fuel options? I'm curious to compare it to my turbo, which is 25.4 per Pumaspeed.
Great to have so many options for our cars.
EDIT
Brake/flywheel are somewhat synonymous, in that they are not wheel HP.....my point is that the 327.5HP figures are not really 327.5HP.

10% is the number used for drivetrain loss on the Fiesta. DHM has used this percentage and quite frankly Russell is very knowledgeable about dyno tuning so I'll go with his wisdom. 330bhp / brake horsepower or crank horsepower is just shy of 300whp (297). The 12.3 pass @ 113 mph car made 313whp on a dyno just as FYI
The charts shown here actually say (fly) which is synonymous with crank there are no deceptions or to cause confusion
If you want to compare apples apples I'll pay someone to do so
for example Turbosmart wastegates for the X47 or the "billet" gate option on the MRX you mention are upgrades
run these turbos on pump gas same as the 330bhp number as advertised on the RT330 states. I would surmise the X47 and MRX would have no chance to match the BHP numbers of the RT330 "as equipped"
wait until you see some numbers with the RT330 equipped with the Turbosmart 14psi wastegate then you may compare the apples to apples you mention
