VRT 24v aftermarket oil cooler for the track

[24vGTiVR6]

During the winter I've been working on the VRT - getting it ready for my 2nd track season with this ride. Last season I saw really high oil temps - the highest I saw was 305F after about 5 laps during a time attack session in 35 C heat.

Recently I noticed that I have a low oil pressure problem. After dropping the pan / pump I found out that the relief valve is shot... and while I was there I took off the oil filter housing + cooler to check it out and I need a new cooler too.... so now I'm thinking about upgrading since it's all off anyway.

I do occasionally have to use the VRT in the winter and sometimes as a daily, so I'm concerned about keeping the oil too cool - plus I have a big eurojet race fmic so I'm not too sure where I would mount it so it would work properly.

There is zero issue with oil getting too cold in winter if you use a thermo sandwich plate. Oil won't flow though the cooler unless hot. I run a mocal in front of my rad and oil temps are under control.. never over 220 on hot days in traffic.

^ thanks

anyone have ideas of where I could mount the oil cooler so it gets good air flow? I'm running a eurojet race fmic so there's not a lot of room in front.

Im running a 25 Mocal with thermo sandwich plate.
Ive fitted my cooler in my front left scoop..neat fit..

Mine is similar but on the other side (ie US driver's side wheel well). Your appears to be in the front right, ie US pass side.

I think that's where I'm gonna have to put it - cuz my surge tank is taking up space on the pass side frame rail. Although I think I can only fit a 19 row in the space I have on the driver's side.... will that be sufficient for a VR?

v-dubbulyuh did u fit a 25 row on the driver's side? how exactly did you mount it?

[vergessen wir es]

Probably not an option for you but here's mine

Mine is a 19 Row and it is mounted identical to the one pictured there in the wheel well. The cooler sits vertical and spans the frame rail above and below. It is more than sufficient for a VR.

Other side has the secondary water rad installed and I have a charge cooler rad I front of the water rad, so mine is the only option available for the 25 row

thanks everyone

I'm gonna go hunt the wrecking yards for a 19 row setrab today and work on fitting it on the drivers side. if anyone wants pics after let me kno.

What is confusing/misleading is that despite you stating that it is in the left scoop your pics show right. What am I missing here?

[sTT eV6]

My oil cooler is in the left scoop as you look at the front of the TT.

What cars come with 19 row oil cooler? I know Volvo has 13 row, and Saab 9000 has 16 row.

good question, I couldn't find a 19 row in the local wrecking yards

I already have fittings + -10 AN braided line so I just need a thermo sandwich plate adapter + oil cooler.... which I'll probably just end up buying new.

[chc-rado]

Check out bat.inc they have load of mocal oil coolers and adapters too. 034 motorsports and BBM has them too. I like bat.Inc

[24vGTiVR6]

I ended up grabbing a second hand Mishimoto sandwich plate & a 19 row.

I want to delete the stock cooler - but the stock cap bolt is too long, so I'm gonna get a machine shop to make an aluminum spacer for me to get the sandwich plate adapter to fit with the stock cap

Also I've got a question about the coolant lines that went to the OEM oil cooler - can I just route the coolant hose coming from the crack pipe down to the nipple on the block?

Think you could post up as you install it with some, maybe with some pictures if you could?

It'd be nice to be able to get this thread added to the FAQ in the 24v forum, because I know everyone always asks about oil coolers, especially VRTs and it'd be nice to have something in the archives.

I've been considering an external cooler for my 24v VRT myself, but mounting location and all the details are still a blur to me

sure.... I always take pics as I go so once I have it sorted out I can update this thread

Not sure if the 24 valve is like the 12 but the stem of the cap should just be a pipe nipple cross-drilled. iirc the BBM kit came with both nipple lengths. see if your stem can unscrew like others. They can look molded together but aren't. If it it's threaded just make a shorter nipple.

doesn't look like it can come apart - it's all one piece and it's attached to the cap. And yah I was thinking I could just cut to the right length and use a die to make some threads. That might be easier.

[24vGTiVR6]

bump-

can I connect the coolant hose from the crack pipe to the nipple on the block to re-route? I figure that's the easiest / cleanest way to sort out the extra coolant lines for now until I can cap them properly.

[vergessen wir es]

I know you want to delete the stock one but you could just run it along with the external and be done. That's how mine is set up fwiw. But yeah you can loop it. That's all the stock cooler is; a loop.

[need_a_VR6]

The Mocal ones come with long/short nipples. You can get the short ones off of really early production 8v that had no stock oil cooler.

[24vGTiVR6]

thanks everyone for the info / assistance

I want to weld some brackets and mount the cooler today and I wanted to know about orientation..... does it matter? The only way I can get the -AN fittings to fit would be if the cooler was upside-down with the bungs facing down.

[vergessen wir es]

They work the same in any orientation. Imho ignore warnings about air pockets.

[sTT eV6]

Orientation doesn't matter as the do will self bleed the system.

wow thanks for the fast replies. hopefully I can get it mounted up today.

the mounting bracket:

[24vGTiVR6]

Installed:



I welded the bracket to the frame rail and up near the underside of the stock grounding point.

[24vGTiVR6]

I also decided to sell the mishimoto sandwich plate and I ordered a Mocal thermo plate for VR6 from INA Engineering. Still waiting on it - I'll update when it's installed.

[24vGTiVR6]

Took a while to get all the parts I needed.... don't ask my why.

It's all installed now, seems to be working as intended.

[creechrr]

How did you get the air out of the core? I've read the core should be mounted with the ports either at the top or the side.
