Maybe I missed this, but how can you keep the blower temps down, without porting it? Will an upgraded H/E work??

 

heat exhanger upgrade, dual pass upgrade, water/meth injection, stuff like that

 

H/E only prevent heat soak. They don't really drop temps much on short runs. The dual pass is the ****, I'd do that. And a H/E is very complimentary to a Dual pass. Also Methanol sprayed before the TB will cool it all too.

 

upgraded h/e with dual pass should net you something like 20~30 degrees difference

 

smaller pulley.

:shrugs:

 

Not even close LOL!

 

I think that will increase heat....

Anyone know the link to the How to dual pass, and how to H/E?

 

sorry, bigger pulley. i had my head up my ass for a second

 

lol it happens to the best of us man

That is the next mods I want to do. I have all GMP, I want to install my manifold. I heard the stock aftercooler is already to small for stock blower. This means mine is not at a good point considering I have stage II.

 

hey i was woundering where i can get one of those for my car never herd of it but i wont mind putting one on my car

 

Go buy the duel pass off crateengine depot along with the surge tank. I believe it comes with instructions. Go buy a used heat exchanger from a cobra at a junk yard or ebay. You can buy the mounts to bolt on the exchanger from Bwoody Performance. Throw some meth on and you have done just about everything you can to keep temps and the blower cool.

it's simple really. the compressor map for the m62 has a peak range of 7.35 psi

this is before the band aid fix of the after cooler, which does help. i'll give it that.

people spinnin these lil guys to 17+ psi is just pissing the blower off. hence more heat and silly hot iat2 temps.

lower the boost, make the motor more efficient. the heads on these cars suck. pure and simple. another band aid fix is water injection. it will help.

as far as doing a new intake manifold with a bigger after cooler. i see this as a bad idea.
keeping all the cylinders flowing the exact same cfm at the exact same psi is a huge task, and im not really sure you want to take the time and go through all the science, flow testing, create/re-create headache to do so.

just me thinking, carry on my wayward kiddies

 

Nos

 

you're fired.

 

he's hired

 

Meth (30 degrees) HE (15degrees) Dual pass (about 15 degrees) Ported Blower (another 15 degrees) = 75 degrees ! (thats really really cool) Im thinking I would not get past 130 after a WOT run and my Temps would ussually be very close to ambient temps.
-Since Heat is what Pop these pistons with all those mods, I really doubt anyone will be blowing up anytime soon.
Let me know what you guys think.

 

so hows it looking up there? dark? smells like sh&t?

 

the remains of pizza hut do not look pretty on the other side

 

If you run the car below about 160 degrees you will actually cause damage to it becuase the cylinder walls will never get enough heat in them to properly expand. What happens then is the pistons start scraping the cylinder walls and not only scores the pistons and the walls, but sends a lot of little metal shavings all through the motor which in the end will result in a blown motor.

 

he is talking IAT2 temps
not coolant temps.

 

LMAO!!! Wow, I guess I'm the expert of cooling mods. BOTH those threads were made by me

 

yeah, Not coolants temps by any means, IA2Ts.

 

I didnt know porting the blower would also drop temps as well. I know all of the other drop the temps. How does porting the blower drop the temps??

 

If I am not mistaken it decreases air resistance/friction and has less surface area for the intake air to absorb heat off the blower.
