Will mp62 overheat engine without heat exchanger
Friday, July 22, 2011 5:38 AM
Just a question is it safe to run the gmpp mp62 kit without a heat exchanger for a while, or will it overheat my engine? It doesn't come with one or suggest you get one in the instructions so I am thinking it works without?

You can run it but your IAT's will be sky high. Resulting on less efficiency from the charger.

It shouldn't overheat the engine unless you are out banging on it constantly all day.

So go ahead and do ti if you want but its a pain to install the heat exchanger/ pump/ lines and/or a dual pass endplate once the charger is in the car, keep that in mind.

Dont people in this case run the Cobra heat exchanger?

I would do it before the charger install, you know its the right way to do it!!

Yeah I know I guess its hard to wait. I know I'll have higher temps. It will probably be only run in winter before I install the exchanger. Just got to save up the funds.

I ran it for like a month with no H/E, you run the charger hard and you'll end up with less HP than with it on, a regular civic was the same speed as me, and i was misfiring like crazy after the heatsoak!

You'll be fine tho. the H/e helps tho.

I would go with meth/water injection if you're not gonna run a h/e...I'll actually be adding meth to my system even with a h/e, the m62 heatsoaks really quick.

what this guy said. I ran the blower for a month without a h/e. put the cobra one on, with the pump and basically the cobalt setup, and the power was better. car ran better, less hesatation and things after romping on it. you will notice a drop in you boost number, but that is normal with the addition of a heat exchanger. power should pick up a bit after the h/e is on, but you might not notice it with a but dyno.

Drop in boost with adding a HE? Should be a increase with cooler IAT's.

my boost numbers dropped a point or so. as far as i know, this is normal. atleast that is what everyone is telling me. the cooler dense air can make more power however.

Yeah I have heard drop in boost but more o2 due to the decrease in temp

I'm running a 3.1" pulley with a cobra h/e, I'm pushing about 12-12.5 psi at 7000rpm. Still a tad sluggish after a few pulls on a hot day, though I'm counting on my cars upcoming meth addition to fix that

Funny u say meth addiction! I was googling meth injection kit the other day at work and I realized how bad that could look to a non car person! LAst thing I need is a co worker or my boss asking me If I have a meth problem hahahaha.

With my car (M45), and no option for a HE, when I run meth I get more PSI, without meth less PSI. Cooler air for turbo with give more PSI, and yes more power with cooler air.

physics > you. Cooler air is denser and since the blower moves a certain volume of air, and then it gets cooled after its compressed it shrinks, thus making less boost because P1*V1 = P2*V2.

Sorry real life experiance tells me other wise.

So for everyone else in the world with the mp62 blower, lower iat2's = less boost but more power, but you're different.

Are you everybody else?

I do not have a M62, but a M45, but it does not matter.

Does the m45 have an heat exchanger ready intake mani? It's a roots type charger as well isnt it?

That's funny you say that. I talked to 2 friends of mine who both use to own SS/SC's. Both stated more psi with cooler temps.

No the M45 does not have a HE connected to it. Charger and manifold is one unit so you can't.

Yes it is a roots style charger.

during the winter my cobalt runs 2-3 more psi in boost

Like it should because your inlet air is cooler, thats not what the argument is about.

Colder air (IAT1) always = more boost on positive displacement superchargers. Denser air going in means more air moved per rev = more pressure against the head. Colder IAT2 does not change pressure much post laminova cores. The pressure drop that occurs due to lower IAT2s is between the blower and cores and the cores and head...Since we don't have a pressure sensor in that region, we don't see it. /arguement.

As far as runing without a heat exchanger - you really need some way to cool it, whether its any heat exchanger, or water/meth. The simple fact that you have an aluminum manifold bolted directly between an aluminum head and the blower means that everything will be fighting to stay cooler than the 180-200*F that your coolant temps reach. With water/meth and no heat exchanger, i can stay below 150* on the hottest days. This is far from ideal, but heat is the nature of a system like this and if you want to make the most of each revolution of that blower you'd do well to invest in every cooling mod you can.

Yeah I think I'm going to do meth / water injection first and then the heat exchanger after. I was just wondering if it was safe to run for a month before I add some cooling. Thanks for the input on this!
