Just been working on cooling issues after my modded x flow seemed hot in London traffic, (not surprised). Put in 11" Spal fan as on the front of my radiator is an oil cooler which I'd reckon blocks a bit of air. Anyway, easy to fix, not much cost, plug and pray. Next I had an insulating foam back kit sheets for an S3. Using these bits (with the nice pictures provided through this forum , most handy) I've been able to retro fit in situ over the pedal boxes and front of tunnel (till it goes on a ramp or rebuild for the rest of the tunnel). Had to mod with sciccors and clean panels to make it stick, but seem firm. Next I got two rolls of Titanium heat wrap, removed exhausts and sat in sunshine wrapping them. Metal cable ties seem shonky so using Jubillee clips. Will take pictures shortly, but wrapped the pipes from 1/2" off manifold to through the side panel for a hint of retro wrap showing. Used opportunity to replace exhaust gaskets. Obviously, have to report back on effect, and doing three things at once won't necessarily tell me whether any or all work or which has most effect...But fingers crossed. My passenger didn't understand why I put the heating on in traffic when temp went up, and explaining to her it was either a new head gasket or shoes didn't help. But I am keen to get temps down if possible on what is essentially to me a street machine, not a racer.
