Turbo Cars During Summer

[Rolls]

A bog stock falcon doesn't lose half its power in summer compared to winter thought, my point was, whilst a turbo car technically will lose more, it shouldn't lose half it's power, hence the standard air boxes are the way to go.

i have the air temp sensor between the intercooler and throttle body so it measures the air going into the throttle body.

the other day when i started the car it was at 0deg and after warming the car up it went up to 2 deg. it is cold here

as for your cars in the heat, just dont thrash it for extended periods of time. give it a squirt every now and then but then also give it some time to cool down a bit and it should be fine.

my pod sits on the front of my turbo and i cant say i have noticed a huge difference, 3rd has slightly less traction when its cold but thats about it.

Well if you are having trouble with traction in 3rd when its hot I think we can safetly assume you have enough power that it simply doesn't matter

I was mainly refering to dudes with stock rb20/25s.

Hahaha

Has any one else got any air intake temperature readings/graphs to compare to mine? Possibly with a decent airbox setup?

Honestly compared to a hot day and a nice cool night mine feels like two different cars. Similar to the difference with driving by yourself or three other people in the car.

my setup is an apexi pod in a cold air box with cai from the grille...

cooler is a hybrid gt

on a hot day i really barely notice any difference

[LANDSCRIBBLE]

I might look into getting an oil cooler, ive heard people covering or blocking them up during the colder parts of the year due to oil temps taking too long to warm up, or something along those lines.

if anyone could give insight as to how much id be looking at to get one fitted to a stock r33 gtst? cheers. also do they all have to be mounted behind the drivers side fog lights? or is there another place better suited?

thanks!

Stick to the standard air box with a high flow panel filter. I´m running 250rwkw and barely notice any major reduction in performance on hotter days. Adding three passengers in the car results in a different story...

Keep in mind as well that it´s not just the hotter weather but the humidity that affects the performance of our turbo beasts. Car companies calculate power using the specific heat of DRY air. I know for a fact that a NA car on a 85% humidity day can theoretically have almost 10% less power than on a 25% humidity day... This would be higher on a turbocharged vehicle. Anyway, a little extra info for all the car nuts out there

btw, I´m not pulling this out of my A$$, I just finished my final year project on this kind of study.

I wish I could run my stock airbox - cant as the FMIC piping is in the way

[simpletool]

Mine is only a bit slower on hot days - no issues with over temp. Running china-spec larger radiator, HDi FMIC, standard airbox with K&N filter. Running 10psi on stock turbo - seems dandy. I'm even getting frosted air out of the AC on humid days.

just peace of mind, install an oil cooler, best protection around for the heat

Actually I would say a large radiator is better protection.

Actually I would say a large radiator is better protection.

from my previous experience, by just installing an oil cooler, water temps stay more constant. As oil temps go up, water temps follow because of the heat exchanger near the oil filter which uses water to cool down the water or uses the water to bring up the oil temp when the car is cold.

Yes a better radiator will cool more, but installing an oil cooler will

1. keep oil temps optimal 2. keep the overall engine temps down.

If you install both an aftermarket oil and water temp gauge you'll know what I mean.

I don't think I articulated this that well.. friday at work, blah

[Rolls]

I would still install an upgraded radiator before an oil cooler.

[JonnoHR31]

i know i should check with a gauge, but if the water temp stays fairly low then is it safe to assume the oil temps stay fairly low to? my oil pressure seams to stay higher which would suggest the oils not getting hot enough

How high is 'higher' ?

Hmm there you go, must be the huge humidity that we get up here that kills the performance.

its really hot here today (37+) and water temp creeped up to 78C (highest it ever gets) and the oil pressure got done to about 1.5kg/cm2 at 850 idle. usually stays up around 3-4kg until it gets over 70C. thats with hpr5 (5w-40). thinking about going even thinner oil after summer, it takes way too long to get hot enough to get down to the right pressure
