How Much Power Can The Stock Cooler Support?

[aquariuz6]

just wondering how much power can a stock cooler from a r33 gts25t s2 support?

how much rwkw can they handle before you would need an aftermarket cooler?

Well, i've been told by a few people that the R34 GTT cooler is good for around 200rwkw. The motor puts out 206kw at the flywheel, so there's a little room to expand on an R34.

I swapped my R33 cooler over to an R34 cooler, and the difference in core size is obvious, so the cooling may be a bit better. The stock R33 item seems to have smaller end-tanks and in/out holes, so i'd put a guess at 170-180rwkw? You'd be more worried about the intake temps at that kind of power rather than how well the cooler will flow.

it would more depend on turbo size and boost pressure and outside temperature. the higher the boost the higher the temp, but if you have a bigger turbo you get the same power at lower boost.

Its not also just a matter of power, but how _long_ can it support it. ie its heatsinking capabilities.

Ie go boosting in the hills for half an hour on a warm day and I'll guarrantee you'll burn your hand on it, even with say 150rwkw. However have 200rwkw and have a 5 second fang in a cold night and it wouldnt be has hot as the previous example.

Basically for heatsinking purposes, all stock intercoolers are built to a budget. ie quite poor.

I'm with Busy2k.

as everyone has said, depends on how much power you're chasing.

I also have a R33 GTS-T Series 2, updated cooler with r34 cooler (very easy upgrade, almost straight swap). Running 190.3rwkw fine.

The FMIC gives you more consistent power.

When the stock item becomes heat soaked (which is very very quickly) the car will be down on power not to mention much closer to detonation.

Give it a little bit of a warm day and ping ping ping.
