Hey everyone, just wondering what are your iat2 temps!

When I WOT, it goes over 180 and my regular driving sits around 150. My pump wasnt working so I smacked it with a hammer and its back to life. So its working for now, but the temps are still the same as yesterdays.

What you I do to lower my temps to a normal, safe temperature. I have a zzp #3 heat exchanger, injen 2.5" coi, 2.9" tvs

Thanks a lot!

 

put a pump on it

 

pump for sure needs changing. my m62 with a 2.8 and no name h/e doesn't get over 150 on a hot and humid day WOT

 

Dual pass endplate

 

no

 

Alright, so its the pump for sure then? lol

 

Stop beating on the car and change the pump.

 

Ok. I read one part where he was asking How to get lower IAT2s.

 

get a zzp phenolic spacer

Cobalt & Ion ---> ZZ Performance


and put this on the fron and back of the lower intake manifold

I apologize for the threadjack, but lol, I saw 190* doing 2 highway pulls, what the hell is going on? the first pull i let off at around 110 mph, and then the second one around 120 mph. I just replaced my ic pump maybe a month ago or so, so that isnt the problem. I wanted to do a few good pulls on the tvs but as soon as i saw 190 i was like holy **** i think thats enough for the day. I have the ottp h/e. Why were my temps so high after 2 pulls?

 

I'm running 180 during driving but when I sure at idle it goes from 200_220 then it drops back down. My car us stock minus the air box mod

 

We aren't talking about engine coolant

 

whoops my fault and that is why I'm cautious on what I post.lol

 

its all good man

bump.....anyone wanna chime in?

 

air in the system will cause that

 

How can I tell if i have air in the system? I also was thinking about this when I installed my option b, I used a 90 degree fitting to run the 3/4" hose from t fitting to the opt b tank, do you think this is hurting me?

 

if the option b isent hooked up correctly it can did you install the bleed line with the restrictor orfice in it

 

yep

 

Uhh... YES. A great improvement when I installed mine took longer for the temps to reach high and cooled down much quicker... but you definately need a pump first OP

 

I think I'll get another pump tonight from zzp. It doesn't seem to work correctly. Might as well get the Option B and dual pass at the same time. Seems a bit complicated to install tho

 

yea my option B took about 3 weeks for it to work right...i ran the car with the lid off for about a week then it started to run right lol

 

I made my own opt b tank and it was working as soon as the pump came on

 

Homemade option b, zzp s3, dual pass, zzp phenolic spacer, and meth that comes on at 8psi. I have never seen over 120ish after back to back pulls on my 2.7.
Definitely get a working pump and then get all the cooling mods you can afford

 

will that spacer fit my ls or will it have to be modified?

 

Hmmm maybe I will try this, there must be air in my system bc my temps should not be that high. Diggin the new sig btw.
