NA engines always runs worse map/tip which effects the power output in a negative manner, and without knowing what level of street port as well means that your figure could be in the mean average of what to expect?

Maybe easier to email me mate?

Thought this is worth a revisit as I get asked allot about this! there is some spurious bullshit out there on the internet that is for sure
This example below is of a very relatable engine....
1998cc 4 cyl 2lt turbo set up for endurance racing, heavily regulated (read: map absolute pressure limited) a few years back to achieve parity to a gibson 600bhp V8 4.2lt engine as used in LMP2 classes around the world. There are not inlet restricted and are simple durable motors that do around 70+ racing hours before a mandated rebuild.

This year and last the BOP has jacked up the power a bit to differentiate them from the shitbox LMP2 cars but estimate around ~650bhp is valid, the bespoke race V8 boat anchor engine in the 'Cadillac' was given an air restriction hole increase! thus they could not be passed on the straights anyway..... Mazda finished second just yesterday with this AER Life Racing controlled engine in the back of their DPi Daytona 24 hour car car.

Specific power ~165bhp/lt/bar
**NOTE: These engines in their final year were making from 740bhp to 780bhp***





Below is the 2020 BOP
