I think that will be the way to go. Hopefully the motors being offset will help with clearance and prevent heat soak.

Sucker fans do indeed work better than blowers. Also, thin sheet metal heat shields work better than you would expect. For my 2 cents, you have a good plan for two sucker fans.

Keep tilling the V8 garden and the salad days will be here soon.

Thermal energy ( heat ) gets carried away by air flow. It is the radiation that emits from a hot manifold that is the problem. It gets absorbed and converted to thermal energy.

Reflective materials reflect radiation that is how a sheet metal heat shield works. It also means the engineer that designed the fans screwed up by specifying black for the case of the fan motor. The darker a object is the more it absorbs and converts radiation to thermal energy. The basis of Solar Thermal Heating. Also the reason you cook if you wear black in the summer.

Thought I had the front drive dealt with. Order a left and right axles for a 2006 - 2007 S60R/V70R. Each from different eBay vendors.

The right side fits.

The left side the spines on the transmission are too small but are the same as the right side. Checking reviled the 2007 XC90 TF80SC does have different spine diameters left to right. I have narrowed it down to two possibilities.
① The left axle I got off eBay is not the correct axle for a 2006 - 2007 S60R/V70R.
② There is a difference in left spine diameter. between the TF80SC used in a 2007 XC90 V8 and the TF80SC used in a 2006 - 2007 S60R/V70R.

I am inclined to think it is #1. When I google P30783090 it keeps coming up 2006-2008 V70 D4 or D5. I think these did come with a TC80SC. Perhaps some in Europe can access a better parts cross reference.

Anybody have the left drive axle for a 2006-2007 S60R/V70R laying around? If so could you measure the diameter of the spines on the transmission side. The vendor could be mistaken? The axle might be for a M66 manual not a TF80SC?

Hmm... maybe the middle one is an M66 axle?

Need to find a way to determine what it is. Got any M66 axles laying around?

I got the TF80SC part number of the transmission 36050320. When I look up part number 36050320, vehicle fitment reads: Volvo XC90 3.2l 6 cylinder 2007 - 2013. I pulled it out of a 2007 XC90 4.4L.

I don't but someone on the Facebook pages probably has one.

The TF80SC is marked Volvo Part Number: 36050320. If you run 36050320 through the Volvo parts catalog it comes up: Volvo XC90 3.2l 6 cylinder 2007 - 2013. I did pull this out 2007 4.4 XC90.

Interesting observation... maybe it was replaced? Either way, I guess that means the SI6 bell housing is the same as the B8444S.
