FS: Brand new 41mm 'Bigger' SSI Heat Exchangers

[SkunkWorks]

Selling a brand new set of SSI 41 mm heat exchangers.

These are the new updated version featuring larger 41mm diameter design that is significantly improved and suited for 3.2 and larger displacement engines. These are THICK flange (not thin) and have an O2 oxygen sensor bung in the stock location.

Included are everything as received new including the original documentation and SSI canvas bags. These have only been taken out of the box for pictures.

Price is $3000 USD shipped within Canada and the CONUS. Paypal friends and family or add 4% fee. Two sets available.

Nice heatders Bra��

I’m interested but have a question for all the SSI gurus.

I have a set of thick flange on my SC. Currently rebuilding a 3.2 euro engine and driving a 3.2 us spec targa. Did original SSI thick flange HEs come in different diameters for 3.0 and 3.2 displacement motors??? Or are all thick flange real deal SSIs HEs the same ID????

The originals are all the same ID regardless of thick or thin flange.

Doesn’t seem to jive with the title “bigger”

Bigger, as in larger OD tubing.

As John mentioned, these have a larger OD for the primaries of 41mm - pic attached.

OD of the primaries for the original SSI is 38mm.

Thanks
Understood, however this quote is what prompted the question.

“The originals are all the same ID regardless of thick or thin flange“

So tube wall thickness is greater by 3mm and the ID is the same?
Wondering if there is better flow for 3.2 liter than the originals?

Seems odd all ID are the same.

Why in the world would they make a set of exhausts with 1.5mm thicker tubing? Answer, they didn't.

[Redliner911]

I didn't know these were released yet. Last I saw it was thin flange only. It's unfortunate SSI raised the price 30% over the 38mm

[Scott Longballa]

I agree that they went too high on the price for these new larger SSI's. They are what we've been waiting on for a long time now! Glad they're making them!! I'm assuming they're only making them thick flange?

They are also available thin flanges

Skunkworks,

What is the inlet diameter at the flange. From the pictures I see the tube extends past the flange into the head. Are these designed to fit an unmodified 3.2 head exhaust port?

Thank you

I have a set and will put out 2 videos. Once the engine they are going on is done. One showing open box reveal, and a second on a 82SC case fitment. The engine will be a 3.2 with 10.2CR Mahles, S cams, and RSR size MFI from TRE.
I hope to have the engine done by years end. We're waiting in the S cams and a Fairchild custom MFI space cam.

These are designed for a 3.2 so yes, they will fit.

[LSR911]

Thanks for answering on the 3.2 fit. Once again what is the inlet diameter of the tubing at the flange?

38mm ID

It's Dansk, JP Group, that raised the price. This is most likely because of the new tooling needed to make the 41 mm heat exchangers. SSI never made 41 mm heat exchangers.

[john walker's workshop]

Probably 1/16" wall, so subtract 1/8" (3.175mm) from the OD.

1 set sold. 1 still available.
