which would be a better upgrade first the dual pass kit or the front mount heat exchanger?

 

Good question. I'm going with a bigger heat exchanger not the dual pass. It's just easier.
I'm also curious about the temp differences for each individually too.

 

Front mount with the addition of an Ion overflow reservoir.

Can you do both?!?

 

Yes you can.

not really money does not permit.....yet. mu ha ha ha

 

So you can have GMP Stage III dual pass mod, and front mount heat exchanger?

Intercooler stuff is not my strong point...

 

front mount or dual pass will net you real gains... do both for even more...
I had em both on my car and saw a real nice drop in temps... add in meth injection and you'll be a little above ambient.

 

i would love to do both my wallet just wont allow it. eventually though they are both my next mods.. woo hoo for cool air

 

what kinda gains are we talking about?

 

doin both eventually.

 

Yea x2, and how much would it cost to do both?

 

I got mine from C/A they have the dual pas end plate kit on the site and the Front mount H/E (get to see a nice pic of my car apart for that one) ... I was seeing @240 deg IAT2 after 2 runs with just the 2.5. added meth I was hitting about 160 deg/s added front mount down to about 145 and dual pass I was peaking @120 deg's... and you can def feel the power increase because it lets the engine keep full timing (PCM pulls timing above 160 deg IAT2)

 

whats the best heat exchanger to get?

 

for cheap and somewhat ok a used cobra one (03-04) from personal experience either the cobalt-addiction one or the LFP lightning one.

 

Not trying to hijack but i noticed that you were located in az. I have a meth kit for sale if your interested? im selling it for $175. Pm me if your interested. Ok now back on topic.

 

Yes that is a nice little addition to the bigger heat exchanger.

I'm thinking bigger H/E, extra coolant reservior and maybe some Cry02 spray on the H/E later on.

 

I need to ask the stupid question of if a dealer sees a nice H/E sticking out of the front bumper, will they take away my shiny warranty?

 

They shouldn't but knowing chevy-Ya they probly will!

 

yes they will void your warranty... thats the main thing that cost me mine.

 

Seems to me you are not really picking up that much power with the dual pass unless you run 100 octane.

 

get the gm lower grill from the 2.4 ss and they wont see shat;P

 

its not really overall power...its reliable power and consistant power from not raising your IAT2's over 160 thus having the PCM pull timing.. please read my posts... I pretty much spelled out what it does.

 

Will the dual pass cobra H/E that lightning force performance sells fit behind the cobalts bumper?

 

should... we have a good amount of space back there.. specially if you remove the stock HE and AC condensor like I did.... lol
