We suspect that because of the extremely close proximity of the downpipes to the back of the block, cylinders 4 and 8 were getting extremely hot. We wrapped the downpipes in DEI titanium wrap twice, and reassembled.

After further testing on the dyno, 90% of the smoking immediately went away, everything else left unchanged. We began wrapping the downpipes on all of the F10 cars cars we've put together since
