i've read alot of mixed reviews bout running the stock h.e with an upgraded one..i just wanna do if theres any downside...pros and cons?

 

im runnin just the stocker but ive read its better to just use the upgraded one with the dual pass and option b

 

i dont know of any cons but it helps more if u run both, the stock h/e does little work but it does do something. And of course the aftermarket one does alot more

 

i run the ott heat exchanger with the extra inline resevoir aka "stu" mod with the stock endplate and it seems to be working quite well. I only see IAT2's get to about mid 130's at the most even on a hot day.

 

This is what I have done, and have removed the stock unit...

 

everyone has there own opinion... no 1 has done any tests yet( if i had money i would) but i would say to use both because of more coolant u can hold the more collant= more cooling... but on the second hand it could be a waist to have the second h/e ( might get no air and could cause more heat from the motor=more harm than good)

 

I just intalled a heat exchanger and i love it. Next will be dualpass!

 

That is an incorrect statement. You only can cool so much vs. with the cubic feet of heat exchagner. Adding more liquid to the system doesnt cool better.

This has been brought up like 800 times, everybody has a different opinion.

The stock H/E is getting air pulled from the fans at a stop, you may lose efficiency while you are stopped because it is sitting in a different spot.

I dont see why you couldnt run the stock h/e first then the after market.. Seems like it would be more efficient. But have never done it, so I dont know.

 

I have heard that if you keep your stock h/e, add an aftermarket h/e and option b, that you will be pushing your pump to the limits because it pumps based on volume.

 

All pumps do that.. You dont need a option B when you get another H/E, that is when you get DP. Plus you have to check the ft. of head the pump can push out and check all lines and pressure drops from the equipment to see how much room you have to play with.

 

I don't think there are any significant pros or cons to running either setup as far as cooling is concerned.

More volume in the system means more work for the pump though, so you may want to consider that.

My setup will look like the following, for better or worse:

Dual-pass end plate
Opt. B
Stock h/e
OTTP h/e

These are my stats with a 100% stock cooling system (working pump):
ECT is thrown in for reference even though it is not part of the S/C cooling circuit

Starup
ECT: 115
IAT: 88
IAT2: 88

Light cruising
ECT: 180
IAT: 91
IAT2: 113

First 1st-->2nd-->3rd Pull
ECT: 183
IAT: 90
IAT2: 129

Second 1st-->2nd-->3rd Pull
ECT: 183
IAT: 90
IAT2: 142

Third 1st-->2nd-->3rd Pull
ECT: 183
IAT: 91
IAT2: 142

(All pulls were within a 20 min time frame)

Would anyone with just a heat exchanger mind posting similar stats?
