After the cam swap, I've notice a big difference in engine temps. After 30-45 mins of parking my car in an inclosed garage, it heats the whole garage 15degrees (like walking into an inferno). So my question is this:
What can I do to cool down the engine more effectively? Would a better fan do any good? (if so any recomendations) Possibly a vent in the hood?
I know this extra heat has got to be affecting the performance a bit too.
Thanks all!!

 

just a question, what cam are you using? i have an oz i am looking to change the cam next sorry i dont the a good answer for you.

 

RPW stage 1.5

 

How high has your coolant temp raised, if at all? If you're not seeing it there, then you shouldn't worry too much. You're always going to be hottest idling (esp after a hard run) too because you have no more air flowing through the radiator (which will still be hot).

 

I agree. As long it doesnt show on your thermo then its no biggie. Cars today run extremely hot.

 

take out that thermostat, it will make the car run colder, but it will also tax the water pump a little more. or a higher peformance radaitor, i heard the evos have the same one as the lancer. or you could always get a vented hood also. =)

not much temp change in the coolant, but doesn't the hot air effect the SRI?

 

Jeff,

obviously a vent would help but I would be nervous cutting your hood and such. Maybe try venting your wheel wells or something like that?

 

wrap the headers in heat wrap. kinda costs much but i've heard it's worth it. 50' x 2" for $37, i think? probably will need more than that though.

 

$37.99 for DEI thermal wrap from Summit Racing.

 

I was thinking about that too Rhyzin, but maybe a heat resist coating. I really don't want to cut into my hood either, but I may buy a vented hood to throw on when I need it.

 

They also have a silicone spray coating that's $6.95.

EDIT: And it's prolly hotter due to longer intake and exhaust valve open times.

Oh, and the heat wrap and spray can be used in conjunction with each other as well. Spraying the wrap will not only increase thermal retention capacity, but it will also prevent deterioration of the heat wrap.

 

Get a CF hood.. Functional vents... plus they looooook so hot

 

About the heat wrap, do it wrong. You'll trap moisture between the wrap and header. In due time, cracks will develop on the header.

 

A turbo timer leaves a fan on after you shut the car down, right? Maybe you could put something like that on your car, even though it's n.a. Or are you looking for something to cool it while you're moving as well?
