HELP - High IAT2 with C&R HE

[BrokenCool]

Hey guys,
So, I recently datalogged my car b/c I noticed my moroso reservoir was extremely hot for only 10-15 miles of city driving. I have installed the C&R HE and recall my reservior being luke warm to the touch when i first had it installed.

Anyways, today and thoughout the week I data logged my car and I saw my IAT2 where at 140-150 from just city 10-15 minutes of city driving.

Today's city driving datalog - iat2 144, iat1 100, engine temp 196.

I do hear the fans when the car is on and the water/water wetter circulating in the reservoir.

Are these normal temps for 90* weather on pump gas? If not, any ideas on what could be wrong? :shrug:

Thanks.

Did you check your intercooler pump ? Did u check for air pockets ? Make sure also your fans are kicking in right and not just at medium setting . Also , is always good to invest on a the reische Tstat 170 ...

You've either got an air pocket somewhere, low fluid or your intercooler pump is not flowing at the appropriate volume.

This can happen occasionally even though 144 isn't excessive it should be lower than that. I suspect your intercooler pump is fading or possibly check your alternator voltage. If you alt voltage is down the pump slows down and so does everything else thus making for a hotter engine.

Well I ran the car with the reservoir cap off for about 20 min and still no change.

What voltage should I see from my alternator? And how to I know if my intercooler is on its way out if the alt is fine?

Is there a way to burp the intercooler system? I have the C&R HE from Revan and had great results with the stock pullied blower. With the pullied TVS the computer is pulling timing because of 135 degree IAT's. Should timing be pulled at that temp?

Let's first log voltage with you SCT tuner. You should have 13.9 plus volts in the charging system. Then you need to check voltage to the pump and make sure it is consistent with ALT voltage.

If you are pulling timing at 135 that is a product of the tune. Check your voltage as well. Voltage is so critical on these cars I cannot STRESS it enough!!!

Well I datalogged and had autozone test the alternator and it is bad. I did research and everyone recommends PA Performance alternators, so my question is should I go with the 130 or 200 amp alternator?

 

[evasive]

200 amp. Revan Racing sells those as well IIRC.

When I get mine it'll be 200. You'll have reserve that way. The car will only use what it needs. With the 130, that's all the amperage you can get even if you need more.

Is the coolant really bubbling out of the reservoir with the cap off? It takes a bit of work to get it going right, ask me how I know.

 

[lawdude]

According to my aeroforce gauge my alternator is fine. Last time I checked, there was no aftermarket alternator for the 2010. Has that changed yet?

Though more amps is always better, is it really necessary? I just don't want to spend more then I have to.

 

[evasive]

Sounds like you've added more load than factory so I would get the 200.

Tell me about all of your mods and what year is the car? 2008?

I had a couple of PA Alternators fail and I stopped using them.

Not as of yet lawdude.

2007-2009 are known for alternator failure. You don't have a lot of additional amperage load. Just go with an OEM replacement (rebuild) and you'll be fine.

How high have you been taching the car? What's the highest RPM you've ever pulled it to?

I take the car to redline no higher.

Where is the best place to buy a rebuilt alternator, tousley?

How many miles? These alternators are known to fail. You might be better off just getting one from your local dealer because of the core exchange versus paying shipping back and forth and waiting for shipment and credit a credit card. etc.

17k miles.

 

[Van@RevanRacing]

17k miles.

I've seen them fail at 1,000 and 35,000.

Everybody should monitor their voltage. Get a gauge like an aeroforce so you can constantly see it.
