[Lotusv8]

Been searching this board but I can't find some direct answer to my questions. Here r some of my questions:

Without turbocharging, can you get 25 hp in stock engine ?
I can't find anyone here or in other forum (unless I missed it) were able to attain 25hp.
If so, what are the modification to attain that extra power?

In turbocharging, do you need to lower the compression to boost 8psi ?
Anyone here turbocharged a stock engine? Does it last?

I have a project and I need some help.

Thanks a million
