YD25 Upgrade Intercoolers
Note in the pictures above (3
0n left) how inefficient the large inlet tank is,
evidenced by the heavy build up on the roof & walls of
the cavernous wrong shaped chamber where the charge air
slows right down & tumbles in circular eddies, causing
extra pressure drop & lag. Little things like this make
a noticeable difference to efficiency, & so performance,
drivability & economy. The difference depends on a
number of factors & so is varied & specific to each
application, but is always present.
Following are a few of the data log results during our development programme for the TD42 Patrol. We also did the same programme for both the 3.0L ZD30 Patrols & got similar results,. ( Click me to go to our Patrol Web Page). We have not done as involved programme (the Patrols cost us over $20.000 !! ) for the Navara as the intercoolers are from the same manufacturers, similar & from over 40 years spent on both flow benches & dynos ( both engine & Chassis), I have a good idea of what needs doing. I did spend time on the flow bench with the intercooler inlet tank as the pipe position was different & not good for performance. The outlet tank is a very good design & only needs work on the outlet radius.
Some Results of our Patrol 4.2 Litre Intercooler & Scoop development.
We do not sell front mount intercooler KITS, because the performance of our upgrade intercoolers when fitted with our scoop ( under development), is very close to an average front mount (& better than some), without the hassle of routing the pipe work & then the chance of it rubbing, the extra throttle lag they cause, but importantly, drops the engine water temperature a little, the average front mount increases the engine water temperature approximately 5 to 7°c ! This is very important to consider. An air/water system also raises the engine water temperature, but not as much, but if built properly, is at least 5 times the price.
