I have a Greddy smic intercooler and when cruising iwthout any traffic I generally see on my apexi pfc low 40oC When in light traffic around 49-50oC when in a lot of traffic around 67-70oC was jsut wondering what other people see running the same intercoler. I know the readins on th pfc are not accurate as the intake temp sensor is located under the plenium so just heat soaks. Also has anyone relocated this sensor to get more accurate readings??

this morning I was at around 35C with my Greddy SMIC.

Stop and go it goes up to 50C.

Kinda curious how that is different than the stock.

 

I have the Greddy FMIC and when cruising Im usally at about 27-28c when stop and go its only about 32c, I think 32-33c is the highest ive seen it.

 

SMIC's heat soak like a ****. With my M2 Large, I usually see 29-32 C on the highway and 45-50 in city traffic.

 

That is a good point......... Greddy SMIC does the same job as a M2 SMIC in cooling.

The argument for the Greddy SMIC is that it's CARB certified, fits perfectly with NO hacking or parts bumping/rubbing, and consumes less space that allows more heat to escape.

 

"That is a good point......... Greddy SMIC does the same job as a M2 SMIC in cooling."

That's got to be about the worst conclusion I've ever seen drawn on an IC discussion heh. Geo Metros are as fast as an RX7 at a stoplight or while parking. Under that logic I beleive the stock IC does the same job as the Greddy at cooling and it doesn't cost anything extra. : )

Enjoy your Greddy SMIC in traffic and constant speed on the highway that's about all it's really good for. The others are made for racing.

Kevin, are you saying that the greddy SMIC is not adequate for a track event? if so could you please explain your reasoning for saying this. I am not flaming by any means, just trying to collect information

 

I had the M2 medium and got tired of it rubbing.

I got a Greddy SMIC and both seperate times had the cars dyno'd with everything else the same and guess what RWHP delta I have seen?

A whooping 2more RWHP on the M2.

Whoopy do!!!!

that was worth all the rubbing in the world.

THe SMIC instake duct is not large enough to provide cooling to all the surface area since the opening is smaller.

Can someone with REAL expertise in cooling and aerodynamics of ducts chime in to explain with some REAL formulas????

 

According to my datalogs SMIC normally sits around 65 degrees and heatsoaks to over 85 (also reached this when on a dyno ). Ambient temps do make a huge difference as in the last few weeks it's been 45-55 in normal driving (5 degrees ambient, running 0.8bar). Uprated intercooler and WI going in shortly

 

im a front mount man. I have the apexi fmic from rx7fashion. I love it. people say that front mounts are not very good because they can cause the engine to over heat due to the radiator being right behind them. I say bullshit, i would rather the little bit of heat from the intercooler go to the radiator then all the heat from the radiator going on my intercooler. Front mount intercoolers really dont get that hot anyways, unless you are constantly boosting

Are you measuring the intake temp using the stock sensor in the stock location?

 

Yes, I know it's not ideal, but it's all I've got to go by at the moment (and I dare say most people will be comparing the same).

 

Recently with the weather change in Florida I am at 24-32C. In traffic I am at 45-58. I believe the highest I have had was 72. Stock sensor, stock location. Stock IC definately would not cool down as quick. I remember when that one would hit 60, temps would stay there.

 

Yeah, I guess all of those experienced road racers are wrong....

Anyone that actually tracks their car will prove you wrong. Especially if they still have the twins. I have no problem maintaining reasonable air temps on the track with my smallish SMIC (worst was mid 60s C on a 100F degree day running 13 psi, this weekend was in the mid 40s C on a 50F day). However, water temps are a major issue when road racing FDs in hotter weather.

So, it's not bullshit.
