got-cha but that might be true for turbo and centrifugal motors? my blower is my manifold and intake air temps are measured at the manifold (post blower) so I think it should be a good comparison as far as aerodynamics is concerned.

I will let you guys know soon.

 

The trans is actually probably cooling it down due to the lower running temp and extra capacity of the trans. Doing a seperate trans cooler is a good idea anyway, IMO. An engine oil cooler is fine as well, but just make sure your oil gets up to around 200F eventually. I put one on my turbo setup because I saw my oil temps going to 250F after very easy driving. Now I can do full WOT runs and it stays below 210F. It still needs to get warm enough to boil off water, however.

A high IAT at cruise conditions tells me the blower is already hot and is drawing in hot air from the engine bay, so Jake is correct; your blower is heat soaked. How is your air filter oriented? Have you thought about a phenolic type spacer that supersub makes?

 

Atomic,

Did you use a factory OIL cooler or aftermarket?

 

An aftermarket B&M 30,000BTU cooler with -8an stainless lines

 

the black heat exchanger is the your transmission cooler? that looks small, more like the size of the stock transmission cooler, the 40K is huge, what am I missing?

The reason I said my transmission is heating up the water is because i have a stall converter granted not a big stall but the water brings the transmission temps up real quick and will not allow the transmission temps to drop below the water temps, im assuming my transmission cooler is basically an oil to water cooler and is cooled by the coolant, I have to ask ron davis about this.

Also, I dont like the phenolic spacer deal unless it did not change the plenum volume, seems the spacer is acting like ablower with longer intake runners, hence more mid range torque at the expense of high end power and im saying this after doing some research on the topic

 

That is his oil cooler!

Did you have it plumbed to the factory location? I was wondering how you had that and your turbo feed and drain lines set up.

 

No, the black heat exchanger is my engine oil cooler, I have the 40k trans cooler below it and behind my intercooler. I think the terminology is what is confusing. The black cooler is 30,000 BTU while the trucool trans cooler is rated for a 40,000lb GVW vehicle and can transfer 45,000 BUT, so it is naturally quite a bit larger.

Heres the trans cooler:


I did the lines with this little guy:


I forgot you have a different radiator, but the fact is, you have a warm fluid (engine coolant) heating up a cool fluid (trans oil) since trans oil runs cooler than the engine coolant. If the trans gets over the running temp of the engine for some reason you now have the engine coolant cooling down the trans fluid. Doing it like this stabilizes both engine coolant and trans oil, but puts a lower limit on the temperature of both at the running temperature of the coolest one, ie, if the trans wants to be a 150 and the engine coolant wants to be at 190, they will be somewhere in the middle. This is really a moot point as long as the cooling system is sufficient, but worth mentioning IMO.

The spacer does change the plenum volume, but Ray showed this to be a good thing across the entire range. You can get different size spacers, even 1/4" would do well in separating the hot engine from the cool blower. What Tstat are you using? I would recommend a 160degree one.

 

Nice, it looks custom. Thanks for the pics by the way.

 

If you mean the block, I actually found it on ebay. It has 5 connections: the big ones are -10an, a bottom 1/4npt I used for turbo feed, side 1/8npt I used for oil temp, and a metric one on the top side I plugged

 

Do you have extra support for the hood latch?
