A second H/E won't add power, it will prevent the car from heatsoaking as much and losing power on back to back runs.

 

wtf are we thinking guys???? lets just roll around with a cooler full of ice bags in the trunk and every once in a while put a new ice bag on top of our supercharger

 

Hey, I've seen it done at the track...

 

My buddy used to do that when he came out to the street racing spots sometimes. He'd just keep it on top of the blower the whole time, when he left we put it on someone elses car until he came back.

 

I just cant understand why anyone would buy a modified end plate kit and not bother to eliminate the wacko stock reservoir...

 

Ummm, probably because there is no space for a larger tank under the Cobalt hood where the OEM tank sits. If you look at the pic of under my hood a few pages back you might notice that the coolant tanks are of different sizes. theone on the drivers side is OEM while the one on the passenger side is from the Ion Redline. IRL's have larger tanks.

 

funny thing i have fitted Saturn coolant reservoirs for aftercoolers on the passenger side tower of lets see maybe 12 Cobalts....

 

for those with the dual pass end plate if u have ur stock one still please let me know by pm, im looking to buy

 

Yep, it's easy. I did it too. Did you look at the pic I suggested in my last post? I even have a Ingalls torque dampner installed next to it.

 

what is this switching of lamova tubes?

 

You need to re-route the coolant flow for dual pass, hence the "flipping" or "switching" of the tubes.

 

If you look at my (crude) diagrams, the lower 2 laminova coils need switched around in order for the fluid to go correctly with the dual-pass endplate. You are re-routing/re-plumbing the entire system.

 

anyone have a pic of this?

 

Pic of what, the whole system or what?

Please refer to page 6 of this thread.

 

Tennpen and domin8 I looked at those pics again, nice installs, congrats guys,and really helpful information I hopethe forum appreciates the time and effort you made to show this. Something i learned is to run the hoses from the reservoir sloping down to the h/e laminova pump area, not going up or along the level of the reservoir. OPtion B is self bleeding to be sure, but why go to extra work when water runs down hill ?

hair brained idea.

build a dry ice box. fill with said dry eye. run the take tube through said box. remember to vent said box. or box will not like you.

dunno, just a thought for those concerned with iat temps

 

Would help for sure. Cool can for the fuel would help as well.

 

Wow I dont think I have ever read that many posts at one time .lol ok I am going to try and apply common sense to this .If I take a water pump that pumps 225 gph put 1" hose a Y(like a dual pass endplate) on it changing it from 1- 1 " output to 2-1" and measure the gph out of the 2 combined its still 225 gpg just less coming out of each so the dual pass is doing nothing you will not see a diff on a dyno .


.For the dual pass endplate to be any advantage 1- it needs a bigger or another tap on the single side 2-a higher flow pump to push the extra or just make it so you use 2 seperate setups 1 pump each line going into the plate, 2 exit ports 1 going to each H/E ,H/E back to pump. oh and you would need a check valve on each line and pumps need to be matching gph pumps also I do understand with the new routing inside the water runs a shorter distance ,but realize it stays in 2x as long

 

Wow, that sounds like a lot of work for basically a dual-pass/option B setup

 

ok then you did not read it correct or I put them 2 close together .If you put a system on like I described you would pump 2x the amount of a dual pass as people are setting them up and using them. people are still pumping the same amount threw it as a stock set up.unless they upgrade to a higher gph pump

 

The pump is adequate (as long as it's working...) to provide the amount of cooling needed. If you were to go through all the trouble to make this work, your money would probably be better spent on a meth system. An upgraded intercooler pump is not worth the money, IMO, because the stock one already flow 6.9 Gallons per Minute. An additional heat exchanger and/or a meth kit would be much better options.

 

5 gpm but thats still ok....tennpenn83 you are usually right on the money

 

If The pump is adequate then no need to use a dual pass plate.Since you are not gaining any flow . I already have the extra 2 qt tank ,cobra H/E and upgraded pump.Bigger pump flows more water through the system, increasing the potential for cooling far more then the dual pass and cost less .My pump flows 500gph so 8.33 gpm so 3.3 more gmp then stock and cost less then a stock pump and for even more cooling at idle or slower speeds add a fan behind the h/e A 7" fits well behind the cobra h/e and they are cheap around 50$

 

Link to the aftermarket pump you are using please??
