What should my IAT's be when im in idling, cruising, and after a pull? I have an OTTP heat exchager, dual pass and an Option B.

 

depends on pulley and it'll be different for everyone, way too many variables

 

GMS2 pulley, and mine are at like 130 just cruising around...i feel like thats way too high

 

Many people say about 20 degrees above ambient temp. Mine usually runs about 25-30 degrees above. First check your fluid level and make sure you see coolant flowing.

 

yeah that is way too high it's like 40 degrees at best outside right now lol, check your hoses for kinks, did you do the laminovas correctly, did you do your hose routing correctly, do you have the .040 orifice in the bleeder line, etc.

 

130 sounds normal, what temps is your weather at?. I had the TVS with stock pulley, meth injection, CA H/E, 2 step colder plugs, injen CAI, 11.9afr and 25* timing and i was only seeing 140* after 3 pulls back to back on a 35*C day.

 

its like 50 degrees out

 

He said his is at 130 cruising around. Mine stays around 70 when I cruise on a mid 40 degree day

 

lol 95 degrees on a stock pulley, more efficient (less heat) blower isn't really comparable to an m62 in 50 deg weather.
but like i said you can never accurately compare iat's with someone else way too many variables. 130 is too high though.
also check ic pump.

 

how can i tell if the pump is dead?

 

eh with option b it's kinda hard, is it the og pump?
if it is and you've got 40-50k on it i'd say it's a safe bet that's what it is.

 

yea its the original pump and my car has like 70k on it

 

oh wow haha, i'd say that's the most likely cause then.
you can try tapping it with a hammer or something to see if it'll start up again, that won't work forever though haha.

 

how much are they to replace?

 

Cobalt & Ion ---> ZZ Performance

 

Bosch Intercooler Pump - Over The Top Performance

or just search ebay for bosch intercooler pump
it's the same one used on 03/04 cobras

 

opps, missed that, yea something is fuckie...

 

how will tapping it with a hammer work? and should the car be on when i do that?

 

it sometimes causes it to loosen up.. its a trick for nearly any pump but as stated its a temp solution. and yes do it while its on

 

Someone correct me if i'm wrong but there are like metal brushes on the inside that after a while get stuck. Hitting it with a hammer will knock it loose and it should work but only for a little while like a week or so ive seen peoples go a month after but you should definately replace it. Hit it with the car on

 

lol ill try and see if my temps go down, and look for kinks and everything. Somethings always wrong...

 

that is too high for those mods.

if it isn't the pump, you have something plumbed incorrectly.

 

Is there any real way to tell if the pump comes on?

 

i tore into my pump and you wouldnt belive how much crap falls out. after i did that its hasnt stop working. there is a how to on doing it pretty simple. if you take the filler cap off and put something in it like a straw and see if it tries to pull it, or move from the coolant being pulled. that or pop your hood go and start your car and get out real quick and stare at the filler neck. if nothing starting going threw or bubblen its probely bad. it take about 15 sec for the pump to kick on after car has been started.

 

I have opt b, should i be able to see movement in the tank?
