Did he mention camshaft, was it also stock?I had an interesting discussion with the owner of BJP Race in Sweden when I was looking for injectors. It turned out that he built 3 UT Mk1 engines 15 years ago. With big valves and ported head and Mitsubishi turbos. They produced 240 hp with stock internals. Whats even more fun, they are still working. Peter Björk (shop owner) meant that 400cc injectors are necessary to obtain this level. He also ment that modern injectors perform much better than legacy ones, so even a bigger injector would work also on lower revs and load. He recommended a Standard SMP 440cc that would fit (EV1) with *hose mod* and top adapter. The price is reasonable so I will go for those.
Now I am going to eat the next part of the elephant:
I think a Liquid to Air Inter Cooler would be best on our mid-engine cars. A lot of heat are generated and not much space available in the engine compartment. I've been looking at PWR and AVT IC's but they are very expensive compared to the IC's on Ebay, Ali Express etc. I've been warned about China made IC's; bad quality, poor cooling, pressure drop... But after watching this I am not really sure if I will spend 3-4 times more money to have a branded IC/Heat Exchanger.
Have a look a these videos. The first one is a "scientific test" the second a "On Road test".
