NOTES - # 1
L - is the core length between
header plates (the length of the charge air travel).
W - is the width across the core face, which when multiplied
by L gives the surface area too be cooled by the ambient air.
T - is the Thickness the ambient air travels through the core,
and has the least effect on cooling.
- # 2
These measurements are the overall
outside size the intercooler needs to fit. They include an average
length for the pipes out of each tank, but not any mounting
- # 3
The optimal kilowatt figure is to be used as a guide only !
As an example - Rob Vickerys intercooler core is only rated @ 850 hp
but is making 1072 hp at the wheels & so over 1300 flywheel !
- Mick McGreggors i/c. core is only rated @ 200 kw. but is
making 300kw. ! - Darren Watters i/c. core is only rated @ 135
kw. but is making 215kw. ! ALL these engines will produce more power
if fitted with the correct size intercooler.
Check out our
intercoolers must read
article for more information regarding sizing an intercooler for
you combination. The most important factor after power output, is
where your turbocharger will operate in it's efficiency range, and
one of the least important, money - if you can't afford to get it
right, save it until you can - your engine will thank you for the
rest of it's life !

Garrett & Spearco
bar/plate cores are more efficient at cooling per cu. cm. than our
own, but also suffer more pressure drop & Garrett can have leaks
from new. In all cases they are dearer to buy (prices listed here
are for our range), & in most cases we have too charge
extra too straighten the Garrett charge air fins before welding
tanks, but they do have there advantages.
