[TECH] 3a dyno in and I am disappointed, sorta...

[txrocco at sbcglobal.net (ATS - Patrick Bureau)]

Brian I understand what is the most $$ efficient way to HP producing power
plant, the point I am making by trying to get the most of out of my 8v is.

To prove to myself that I can put out as much HP as I can out of it,
(thinking process of building an air aspired engine is much more challenging
than splapping a turbo (no offence to any self-turboed owner this is not a
bash follow on my mind process) but any kid that owns a rocco 18+ wants to
build a car that will eat Hondas with turbo Vtech.

Personally all I need is to hold off on my speding for a few months and PAY
someone to do it for me.. But that would defeate the purpose of the creative
mind,  for example underpulley can provide # amount of HP versus a normal
pulley on a dyno (been done thousands of time, over and over and increase an
turbo engine from 170HP to 185HP..)

But I am talking about, air aspired.. every once counts to get 1 hp...lol
its not about.. My car will beat yours.. heck I can do that with any
american muscle can against any tubo car I know out there on the market..

I have driven the 1/4 miles at 9.2 seconds.. speed is no longer a NEED for
me, I enjoy it... but my mind is basically trying to find a creative way
mechanically to improve a small engine to a very respectable power band, and
if it does not impress anyone that an 8v 's potential can be 140-145HP air
aspired, so be it...

But I'd like to know if I can reach it, because to my knowledge (and I will
admit not knowing it all like Larry does), there is not 300 air aspired car
8v that do that number compared to the number of 1.8/2.0/8v turbo vw that
produce 185HP... and in my eyes, being part of the few, that are "different"
is what gets my adrenaline flowing when I look at my car..

its just me... or I am "old school" sounding tonight ?
