Thanx for that. From what i've heard about this subject,the low and mid range of a compressed turbo setup is more apealing to me than out and out mid to top end power.I would be very happy with a motor that pulls from nuthing to 8 grand with a couple of hundred h/p.Not realy a lot to ask for.I got an n/a c/a for free so thats why the interest in the blowers effect on this particular setup.
