How to get 300bhp at 1.0bar




	Brother firkins asks: ...besides cam, turbo and intercooler [what 
needs to be done] to get 300hp @ 1.0bar...


	Funny you should ask.  Got the math laying around home somewhere 
that can get very close---if I can find it tonight I will post it.  In 
general terms you need the following:

	Much larger turbo---something on the order of a turbo from a 
930.  k27++.  Obviously, you need to match the intercooler to the turbo, 
and have a cam reground.  You also will [*if* you can reach 300bhp @ 
1.0bar with the I5] need mucho flow with header / exhaust; reconfigured 
fuel delivery; and, the engine will be bored and stroked. Head work is 
necessary as well.  

	300bhp @ 1.0bar is very difficult and expensive on the I5.  On 
the Porsche 6 you can get very high hp numbers at 1.0, but even that 
requires a huge turbo / intercooler and stretching the motor's insides.

	This is where we need to focus, I believe.  At 1.0, compression 
can be much higher [in fact will be much higher] without the scares that 
we should now all have at 1.8+.  

	I will try to post specifics when I find the bore / stroke 
numbers I have been playing with.
