I assume when I do it I am removing the top plug on the stock h/e and leting it run until i see a steady stream of coolant and not it swelling up and out then back in right?

 

If you had opt b I would be of more help to you. I havent bled the stock filler neck setup in years.

but yes, the plug on top of the stock heat exchanger is a bleeder plug.

 

From my personal experience when I added my dual pass, h/e and option b I didn't really notice any drop in IATs after a pull but found the temps to recoupe much faster. What I meant by that post is people are saying 160* after a pull is too high and that's why it's knocking where I ran those temps for a few months with no issues. When I drove mikes car after you tuned it down the highway the temps were at 150* and went to 190* after a pull. I told mike right then and there something isn't right. He found the pump not to be coming on which is what I kinda thought, smacked it with a hammer and it kicked on. Then started seeing temps like 105* down the highway and 160ish after a pull. But the car still continues to knock like crazy.

 

It's all in how the tune is set up.

GM tunes start to pull timing when IAT2's get to around 140ish.

I know Vince is very conservative with his tunes so I have no doubt in my mind he kept a lot of the fail safes as they are from the standard GMS3 tune.

160*F after a pull is rather high, and if Vince is correct about the 200*F IAT2's than its no question as to why his car is pulling so much timing & seeing KR.

 

hmmm.

and like i told mike. the butt dyno is noticeable that there is power being lost. I hope the bleed works. I really want mikes car fully opperational before i leave for calgary on thursday.

 

I remember when my car had trapped air in the cooling system. For one the car would not drop IAT2's after a pull along with temps toping out at 160*F+. It was aggravating, but once I bled everything my temps went back to normal.

I also felt a noticable power decrease at the top of 3rd as well.

 

Well looks like there is a lot of air in the system let it blled for like 20 mins and all it did was bubble. Man I thought I had done a good job on that before.

 

It happens man.

I bet your IAT2's will be much better after a pull now.

 

We can re datalog once your ready mike. I should have some free time tonight hopefully.

 

Good to hear. Now let's make some powa! Haha

 

Meth? the Drug?

 

That would explain Vince seeing 200* IATs lol

 

that was tasteful.

 

cant do it tonight got a movie date. but maybe tomorrow. I wanna bleed more as I only had a bit of time at work to do it. and also drive around a see if it helps the KR3 if not no sense doing another data log if we still have the issue right?

 

I didn't say it to bash? But mike sees 155* IATs and Vince sees 200* IATs. Still don't get that

 

I wasnt calling it a bash. I said it was tasteful.

Truthfully Mike said he saw 180 IAT2 temps.

I don't think Vince is going to make numbers up. My guess is it peaked somewhere high of 180's-190's and he generalized it by saying "someones iat2 temps hitting 200* is not normal"

 

Is mike recording his IAT2's on the interceptor, or just going WOT and watching them. You will def miss peak IAT2's if you dont record them. I say record IAT2's and rpm at the same time, along with IAT2's & knock. Might help determine where and when the problems is happening.

 

Ya when I drove mikes car his
temps were 190* but last nite he
did a pull and said it didn't go
over 155. Whatever i just hope this is the problem.

 

So how do i record on yhe interceptor. I tried one night but didnt figure it out and then how to play back the recording.

 

Should be in the menu section under record. IIRC. I never used it but i thought i saw it there.

 

Just found an online manual so I have learned how. Stay tuned for more as I feel a disturbance in the force. Muhahahahahaha.

 

Thats what i tell my girlfriend everynight...hahahahahahahahhaa


then i sleep on the couch...

 

That was tasteful!

 

Thats what she ...said?

 

after you bled it, how much coolant did you have to add?
