with any cams more than BD10 the pistons must be pocketed. NOT TRUE
Why the obsession with bhp? your car might make 400bhp but be about as drivable as a squashed slug!
AGAIN NOT TRUE
Im going on what i was told by not just Karl.
and how do you know any 400bhp cos is driveable? it was a generalisation.
its likely it'll drive very well, but you know about most of the bigger power japcars that have been tuned in japan only have a narrow power band
As far as your first q is concerned Mike, one has to set oneself a target. Whilst bhp is not the be all and end all, it helps to work to a goal, else you can just drift between a defined specification.
In respect of the second part of the question, I know where you are coming from, but this was kinda the point of the thread - to make a 400bhp engine that would do the job well, not just do the job. This is the primary reluctance to dropping the comp ratio.
A number here have posted that their low comp cars still drive well throughout which is interesting - this is turning out to be a very good thread - comparing each spec helps to see the pattern of similarities.
