hiya,
im just wondering- aswell as fitting a secondard aux fan to the passenger side of the front of the rad....
what do people think i should do to get vented air to cyl5 and 6?

i'v been thinking either chavy vents on the bonnet (wehay actually bonnet vents that have purpose and i have a spare bonnet to play with luckily)
or have two ducts clipped to the back of the rear rad fan and use the rad for the air supply

thinking about it more indepth i could put mesh on the fog light plastics and put ducts there (needs to be moving though really for that to work hence why i said behind the radiator

let me know
thanks

from some miggy modification sites I remember they increased the water flow capacity of the block..(they really dont give much detail) ..
and they used higher capacity water pump..

also air cooling can be done but I think it needs extra cooling surfaces mounted.. :-/

also I see somewhere else they do port polishing on V6 air inlets..

The problem is the air slows down under the bonnet so venting the hot air is a must. Yes a chavy vent in the lower wing or even the bonnet will help  :-/

yeah, if i could then i'd go for more subtle air vents like on the camaro

ER..........yes, ok I think. Getting rid of the hot air rather than trying to push more cold air into the engine bay is the way forward

how would i be best going about pushing hot air out?
i'd need cold air coming in to replace the hot air.

unless your suggesting i have a complex hoover like arrangement
-cold air coming from the top via vents, a hairdryer fan lol! and then it going out by the exhaust manifolds!

If the exhaust vent for the hot air is greater than void for the cold air you have created a vacum, which will drag in more cold air. At the same time you dont want the hot air exhausting under the car as this will cause turbulance and compromise the road holding.

point taken ian!
you could just force cold air in and try and disperse the hot air, anyway those camaro vents are at the top, and we all know hot air goes up! lol...
might have to try and get some templates drawn up for surgical bonnet operation! lol - just wondering what shape would look best/which way round to have them

The cylinders are cooled by liquid. Getting air to their vicinity will do nothing at all!

Spot on - specific heat of air is so much less than that of water.  (http://en.wikipedia.org/wiki/Specific_heat_capacity)  the table about half way down the entry shows the huge differnce.

i swear my v6 has 2 fans! does the 3.0 have 2 if it does why not just swap the rad?

afaik the 2.5 has a single fan and 3.0 has the twin fans...
i happen to have a set of twin fans

just a question,
how much does the low running temp thermostat lower the temperature?
