When in reality all they have to do is to raise the rev limiter just 400 rpm higher (from the actual 7450 rpm) even if the power gains would only be marginal (say 10-15 hp).
How?! Just loook at what insideline said:
And they are right about this... so let's go back to the math:
7450 rpm (BRZ's rev limiter) * k (const.) = 59.2 mph
y rpm (new rev limiter) * k (const.) = 62.0 mph
y = (62.0 mph * 7450 rpm) / 59.2 mph = 7802 rpm
So, with the rev limiter placed at 7850 rpm the engine is allowed to rev freely to 7800 rpm and the Toyobaru can reach 62.0 mph in 2nd gear which means that only one 'time-consuming' gear change is needed!
The 0-62 mph (and also the 0-60) time can drop significantly from 7.6 sec. to sub-sevens... say:
2014 New Toyobaru R (racing spec.) 0 - 62 mph in only 6.5 seconds, 7800rpm redline!!!
How about that as pure marketing propaganda?!
True. Either that, or, if they don't want to risk the higher redline, slightly adjust the gear ratio.
