As I recently bought a infra red thermometer I decided to have a play and find out what some of the parts heated up to after a run (15 mins @ 70mph on bypass).

The engine is standard mapped only changes are:-

Forge Blue air hoses

Audi TT wheel arch mod (slotted vent panel glued in)

The following temps are derived from the external surfaces mentioned :-

Stainless charge pipe (at rear of engine).........63 C

Intercooler air exit........................................22 "

Inlet Manifold (approx midway along)..............40 "

Manifold feed pipes to head............................50 "

Exhaust downpipe lagging looks a good idea and a Phenolic inlet gasket (think Bowders has done these) .

Interesting figures there, think it says a lot for having a phenolic gasket, I wonder how many cars there are with FMICs installed which get the temps down to 20 instead of 40 but then as soon as that charge hits the manifold its back up to 50!

Do you think though the air will heat up that quickly when the car is being used 'in anger'?

The figures would be less on the move with cooler airflow

Thats the thing. Whats the difference in performance in real world scenarios to justify nearly £70. Actually, £70 doesnt buy a lot these days.
