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!

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

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?

mrbelvedere

iTrader: (3)

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

sjc0013

iTrader: (6)

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.
