Recently hooked up my scsn tool to my car to see what timing and iat were at. Noticed my iat seemed a lot higher then I remember. They were close to 200f!! and lowest ive seen them go to was around 135f. My question to you guys is, what are your air temps and how can i lower the temp back to what I remember them being at 20 to 30 above ambient? Can it be a iat sensor or a bad pump? Also what are you guys seeing as a normal reading for timing ?


Mods are h.e, johnson cm 30 pump, shorty headers, s.c pulley, intake and exhaust mods and 80mm t.b..

All help is greatly appreciated juat trying to make sure i wont have any issues.

Those are crazy high. Check the pump or see if there is fluid in your reservoir if you have split system.

CM30 do go bad our time. Seems like a failing pump

As Denroll & Shard stated...most likely a bad pump. Upgrade to Bosch 010

i run always about 10-15 degres celcius above ambient with bosch 010 ...no split system

Way high! Is your S/C shutting off at WOT?
I see appx 15-20 above ambient, measured at surge tanks.

Im gonna swap out tthr pump to test with my stock one but thr weird thing is there is no s.c shut off. Car still feels like it pulls when I get on it. If its not a pump could it be a bad iat sensor? But thanks im going check out the pump and get back to you guys were can I find a bosch pump?

My IAT around 190F .. and the temperature is ~100F, stock with 010 Bosch pump ....

bnzuovr

that's the first thing I checked and I do not have a split cooling system. I hope its just a pump.

Hulk

Split the cooling will help, check the pump first

bnzuovr

yeah mine right now it's 73 degrees outside in my intake air temperatures are showing about 145degrees. sounds like you might have a bad pump as well

Split the system and change the pump out. Then look into a killer chiller trunk tank and for extra fun add meth. Super cool IATs

bnzuovr

Thanks guys im gonna try the pump first and see if that brings the temps down. I've been thinking of doing a split system hopefully that will be my next years mod. Which pump do you guys recommand bosch or meszire. Not sure if i want to get another johnson all though it hasn't givin me any issues in the past maybe a cm90?

Wow yes, even on 100F days here, cruising AITs are "only" 15-20F above ambient. I just have a Bosch 010. No split or H/E upgrade.

Hulk

Bosch 010 pump, 90-100$ and you will be happy

At cursing speed? If so, then yes something is wrong and most likely pump. If at WOT, it can get that high and higher depending on your mods.

bnzuovr

those temps were at cruising speeds if im wot for a few mins it will go well over 100f above ambient.

black06c230

With my KC on 95* days I can cruise at 80 and my temps range 75-81*. Love the KC and tank.

I have a CM30 and it stopped functioning about a year ago. It was the fuse. The CM30 draws more current than the Bosh. I think it was originally 10 amp and I replaced it with a 15 amp.

bnzuovr

Where is fuse located? Trunk?

mAMG

I had the old pump installed before and the supercharger used to shut off after 1 WOT.

Bought the new Bosch pump the supercharger shuts off after 3 runs.

Is it possible that the new pump is defective ? Or it's just the temperature here is very high ... ?

mAMG

I remember there where a chart shows that merize is good, and the best was an amg pump which is expensive.

sircl55amg

your pump is dead ^^ or the fuse

bnzuovr

Anyone know the updated bosch pump part # and a recommendation on were I can purchase one at.

Denroll

It's not really a mod you'd need to save up for. I got my reservoir on eBay for around $35 or so.
