I have a cobra heat exchanger on my RL that just made out with a stone.





I know I can patch it and be fine but I thought I would take the opportunity to upgrade to something bigger.

I have seen a lot of threads about upgraded FMICs but has anyone tried a dual pass set up like this?



Which is better? Larger capacity or dual pass?

 

Just buy the CXracing unit and call it a day.

 

Larger capacity H/E is FAR SUPERIOR to dual pass!

 

I was afraid this would happen. I asked the Cobra guys the same question and they are saying the dual pass is better! lol

But I think they are limited by the amount of space they have. So a Larger capacity H/E like the CXracing one may not fit in their cars. That thing is huge!



Another question that I can't find a defiant answer to relates to the Stock Aftercooler.

Right now I have my cobra H/E running in series with the stock unit. With a larger unit like the CXracing one would I be better off by bypassing the stock unit?

 

does anyone have the link to cx racings web to this intercooler? i cant find it on there site

 

its not on their site only on ebay

 

http://cgi.ebay.com/ebaymotors/Heat-...spagenameZWDVW

its a very good deal.

 

type in air liquid intercooler in the search engine, youll find it listed there from cxracing. installed mine last week, looks very aggressive, simple to install, and performs even better at the faction of the cost from cobalt addiction

 

IMO, its always better to run it with the stock h/e cause it is going to hold more coolant and is going to get cooled twice as opposed to once.

 

Sweet , i didn't know about that h/e looks nice!

 

The only problem I can see from that pic on ebay is that the H/E sits what looks like 2.5" below the stock H/E. So what that would mean is that part of it would be exposed to "rocks - which the all are really", but you may have to be real careful about bottoming out the front end of the car and damaging the H/E. Other than that it looks great. I know when I recieved my Cobra H/E it was bowed a bit and had a small dent so on the cobra, whoever had it in there car bottomed that one out and it is smaller.

Mind you, you have a RL and they have a tonne more room to play with up front compaired to our cobalts.

Cheers

 

Yeah. Its defiantly important to mount that h/e as high as possible.

 

ive been looking for a heat exchanger.... but i didnt wanna go with the cobras and cobalt addiction still says 4 weeks backorder i dunno if it still is but thats what it says so i think ill go with this one for my cooling needs just make sure i put mesh to block the rocks

 

I have the one that is exactly like the cobalt addiction one, but sold on ebay and it works great, looks great and fits awesome..check out ebay for the HE that looks exactly like the cobalt addiction one, and its the same exact thing..

 

Good idea. Mesh I mean.

I was looking at the diamentions and that thing is a monster. You may have a problem with the hieght and the width in our cobalts. I would do some measuring befor you order it to make sure there won't be any fitment issues. My Cobra H/E with the Bwoody brackets was a tight fit. The nice thing about this one though is the hose connections are on either side.

cheers

 

I'm running a heat exchanger thats 3.5" thick and 7" tall and it fits well (cxracing is 2.5" thick and is 8" tall i believe), even put mesh in the grill to keep the rocks from killing it. The only reason i went with a dual pass is for the plumbing layout, with our system setup its more beneficial to have the inlet and outlet hoses both coming out on the driver side of the car. Routing around the passenger side takes more finesse and could lead to more tubing crimps and bends.

anything with hose adapters coming out the back or front like the stock cobra heat exchangers, definitely isn't the best setup for our cars either.

 

Amen...Brotha!!! side routing FTW!!!

 

True but the cobras are far cheaper than the others. I got one for 120.00 shipped with everything I needed besides the mounting brackets.

 

Agreed. Cobra h/e are the cheapest and easiest way to get started. I think they are great for Stage 2 LSJs. But IMHO any additional cooling will not hurt. So I figured its time for an upgrade.

Where did you get yours from?

 

griffin racing direct replacement in stock location works for me

 

go to walmart and get metal L bends for like a buck for both then go to auto zone and get 4 feet of 3/4in hose and some clamps, there you go simple as that.. the cxracing fits absolutely fine without any problems, just take off your bumber so you get room to work with

 

that cx racing one you just do it like a radiator pour liquid in. then crank then top it off right you dont have to hook it up like the cobras where you gatta keep as little air out. you know? does this make sense? or any i totaly off on this? i been at work all day so brain is fried

 

Close. Filling the cx racing h/e at the cap would be the quickest way to get started purging the system. But the h/e cap is not at the hightest point in the cooling system so you would still need to bleed out the system just like the cobra h/e.

This brings up another good question.

For guys running the CX Racing H/E, do you cap off the H/E overflow port or do you tie it into the system using an overflow tank or something like that?

 

yea thats how mine is and it was a bitch to install...

and when i talked to them awhile back they had tghem in stock, they just never update their site. the benefits of the C A one is that everything is routed on the driver side, making ease of install and it comes with everything you need to do it, and with stainless steel hosing, which is always a plus, not really needed IMO though. but hey, if you got the money to spend, buy theirs, if not, go with the CX racing one for its the same pretty much and cheaper..im probably gunna upgrade my cobra one to a CX racing one soon also.

 

ebristol whatever h/e you get you just gotta buy a second saturn coolant reservoir bottle and route it to ur h/e with a restrictor in the bleed line. if there is any air in the system you can have an h/e the size of a mack truck radiator and it wont help
