I am building a 20b 3rd gen.... I was wondering how good a FC's oil cooler would work if I could find a spot to mount the thing. I want to get the rotary extreme dual oil cooler kit eventually, but I am getting very low on funds and would like to save some money this way. I've heard that these coolers are good to about 700hp and I'd beleive it since they are so big. The fitting should be easier also since the 20b's front oil line threads on the same way as the FC, and I know the rear lines fit both the fc and fd. What are your thoughts/experiance on this?
Thanks,
Jesse

 

I plan on using the stock fc oil cooler on mine. they arent very small.

 

I just ordered this Fluidyne and associated parts and will be installing it by the end of the month.
It fits in the stock location but has more surface area, is thicker, has a better fin and endtank design plus a larger capacity.
It has been race proven in FC's to improve oil cooling over the stock oil cooler and even dual stock oil coolers run in parralell or series.

Here is a parts list from Summit:

Im keeping my stock fc oil cooler. You still have the 3rd gen for sale soon?

 

Did the same thing as rx. Twin fluidyne's but not as big as his. Rotary extreme's cooler is about 3 to 400.00 more than putting it together yourself.

 

I'm going to use and Fc cooler as well. I believe the key is getting the air to flow through it. That's would be a little hard to do if the air also has to go through the radiator. Ducting would be key for it to work properly on a 20b.

 

Thanks for the ideas!

fcdrifter: I finally ordered the intercooler piping, haha. So... hopefully it will be ready real soon. I have some other projects going on at the shop right now, but as soon as I'm done with them, I will thow the piping back on and get it back on the street.

 

cool just let me know a week or so before its ready and Ill see what I can do. Do you have any pics?

 

I can get pics tomorrow when I'm at the garage... I have some old ones, but it was before the paint job.

 

Get A Pwr Oil Cooler From Australia

 

I run 2 FC oil coolers in series. It takes me about 5 minutes of driving plus a couple minutes of driveway warmup to even get to 160 Deg F. Takes about 10 minutes of driving to hit 180 F and my normal range is 190 to 230 depending upon how hard I drive it on a 60-80 Deg F day. Hotter days it stays around 220-230 F and it works just fine.

 

I heard the pressure drop is pretty extreme with the series setups. I run dual FC coolers in parallel.

 

Parrallel always cools better provided adequate airflow is present to the two and the setup also has less pressure drop than does the series setup.

The Fluidyne oil cooler I just installed cools better than two stock collers, no matter how they are plumbed. Cannot argue with on-track results.

The cooler also fits in the stock location using the stock mounts. I just had to make a tab from the cooler for the stock mounts to bolt to. I also had to plumb in an oil t-stat. Oil temps come up pretty quick from a cold start and stay up in the normal range even when it is really cool out unlike the stock system.

 

That would explain the pressures I get then. Under cold start idle they get to 70 psi but under hot idle they drop to 18-20psi. Normal driving pressures are in the 40-45psi range.

Mind if I ask where you purchased the Fluidyne cooler and the oil t-stat?

 

Here is the parts list from Summit that I previously posted. I did not include any -10 line or fittings with the list. How you plumb it is up to you. I did mount the t-stat to the inside of the drivers side frame rail in front of the engine.

It turned out to be a very clean install...if I do say so myself

A quick note about the -12an to -10an reducers. You need to cut off at least 1/3 of an inch from the -12an side so the fitting does not bottom out on the cooler before the 37' angle seats are set and sealed.
I won't tell you how I know about this

 

Sorry, I'm too ignorant to look through to the beginning of the post and see that you already gave the parts list...duh.

The only issue I'd have is that neither of my oil coolers is mounted in the stock location, they are stacked vertically and between the IC and the radiator on a custom bracket. Pretty sure I couldn't fit a 3" deep cooler in there, 2 is about the most I can do.

 

I've also heard that stacking them will give you alot of cooling issues, chokes the radiator of precious air.

 

My coolant temps stay at 190 F all the time, would think it's more of an issue with having the proper draw of air through there as well as strategic fan placement, ducting, etc.
