I have a 2.8 pulley and i want to know if the heat exchanger is better than the dual pass?

or what is better to put?

 

H/E is more effective IMO.

 

If you can't do both, H/E first

 

I would go dual pass before H/E. That's actually my next mod. I'll do H/E after the dual pass.

 

So what is you IAT2. Mine sit around 135*F winter not sure about summer.

 

are you talking about after a run kaiso?
thats pretty darn hot for winter time here.

my cruising temp IAT2s have been around 30-60 lately.

 

Is that *C Anom. Actually I was cruisin around today and they were more like 115-125*F.

 

*f

thats VERY hot for cruising IAT2s in the weather were in right now....

 

do both at the same time...

 

I'll check them tomorrow again. maybe I'm wrong. We did have +10 degrees today though in Calgary.

 

i think the warmest ive seen my IAT2 for the last few months is 80, most of the time its 30-60 depending on temp.
generally cruising you should be only about 20-30 degress warmer than ambient.

 

I will check tomorrow. I had just got my car back from the dealer and they disconnected my battery and the PCM was doing a relearn. There was a point where I noticed my fuel econ was at 30L/100km then it settled down after about a half hour so maybe I was getting a fucked up reading on my IAT2 as well.

 

id give your IC fluid resevoir a check too (the little one in front of the blower), and maybe check it with the car running just to be certain its bubblin away in there.

 

well I have been having to fill it once in a while. I am talking about less than a quarter cup and it was topped up at the dealer when I picked it up this afternoon.

 

just installed my HE not too long ago. definately seeing better temps.

 

i saw slightly better temps with my heat exchanger. hoping to see alot better temps come spring time. im adding meth and the dual pass

 

WHEN U GUYS TALK ABOUT TEMP is not the coolant temp right... is the manifold temp that u check with a different meter?

 

They're talking about intake temps. It's not something you get a reading for on your display.
Lower intake temps, denser air, bigger bang, more power.

 

Holy crap thats high for crusing especally in the winter, my IAT2 temps last night coming home were a low of 44, average of between 50-60 while cruising, even after a 1-4 WOT run this winter has never exceeded 125 degrees.

I havent even installed my cooling mods yet, just stage 2 and catback for the winter

 

thanks

 

Looks like my IC pump may not be working. I just finished taking her for a good run and when I pulled over after the car got up to operating temp I popped open the IC cap to take a look at the fluid and there was no pump turbulance. Now I just had the roll pin for my shifter replace a couple of days ago and maby when they put the fuse box back in the nocked the fuse or something or the pump is shot.
