Bigger tubes won't help much when all of the flow hits #1 and #2 cylinders first, expands, loses pressure, and eventually makes it down to #6.  For a while I was considering the Pusher intake that has a runner directly to #6, but I figured it wasn't worth it.

 

Btw, this was stock piping with the VPMax boots. My new theory is that this is enough pressure to help push the flow down the shelf to #5/#6. :evilgrin:

Better off without it. Personally your just placing the heat closer to the oil.

 

Then it would help to do some measuring of the oil first before buying coolers. I just spent 4 months where my oil temp never got over 100*F. Then in the summer time I rarely make it over 170*F even towing. Don't even need the coolers.

I ran some quick numbers and looked some of my old heat transfer stuff.  (I could spend a day modeling it and still have a lot of questions on the variables.)

 

Since the exhaust pipe and cooler do not touch, there is no conduction.  When the exhaust is hot, you are moving down the road and the air is passing by, so no convection to each other, but cooling to the atmosphere happens.  The only mode of heat transfer is radiation.  (remember from the other thread, radiation is driven by emissivity...)

 

It comes down to a simple heat shield will in most situations reduce the radiated energy by half.  (watts/foot)  (I agree yes/no lets sit down with lots of beer and argue the finer points...)  Now that is radiated heat, not actual temperature.  Radiated heat is like at a big bonfire how your face and arms will feel like they are starting to sunburn (radiant heat) but when someone walks between you and the fire, you are all of a sudden you are cool.  (they blocked the radiant heat) 

 

Insulation seems to work better on paper.  (according to a spreadsheet I am running.)  6mm of the right insulation reduces the lost heat energy to 1/5.  (I thought the heat shield would be the same or even slightly better.  It may be, as I didn't factor in the the heat loss of the air moving by the surfaces...)

 

It looks like wrapping the area or going to a ceramic coated exhaust in that section would really cut down the heat transferred to the transmission.

Done a mock up on the passenger side fast cooler....

 

So what do yall think about this clearance here...

Heat is the obvious issue here...

That's why I put a filter on passenger side and a heat shield for the exhaust, only used one cooler on the driver side
