thermo's or std fan

[roadsailing]

i thought all fans were slightly unbalanced to begin with

every electric fan i see usually is, they have an odd number of blades and two of them are usually un-evenly spaced.

this is to avoid noise, so you dont have regular "beats" coming from the fan spining, you will find these fans are still balanced.

The PWR rads are designed so you can easily mount the stock fans back on, the only reason I didn't go that way was because I already had thermos and there wasn't enough room with the huge arse radiator in.

if i get pwr radiator i might have to go for thermo's

thanks

go to justjap webpage about$400 40mm alloy bolt a good cond shroud and engine fan on and your laughing.
my customers cars reg make 250rwkw with sr20s and none have a prob.
there is no way a thermo will use 5hp like an engine fan.
thick rads and coolers can block airflow and start multiplying problems.
good airflow to the cores is key to good cooling.
