That would be 8psi over the vacume of a lead foot, say .5 bar thats nearly 1\2 a KG at ISO or only 1\4 KG at 70Deg C.

But i agree with you, i would build Nos Kitts, simple maths. first question was how much more HP, second question was how long do you wish for it to Last.

But Cool always works, big turbos big boost = heat and heat doint work.
One converstion i saw on a sportsman Lotus Espri was the air intake was though a aircon driven cooler, if you do the maths it makes sence to a point

In reality, if you put a turbo or blower on anything and give it a bit of boost, you will get a power increase regardless. Way back (8 years ago) when i was a wet behind the ears p plate deiver, i replaced my ac compressor with a toyota SC14 supercharger to my 300tdi defender ute. Fitted a 90m pulley and fed it through the turbo. Now before you say this would not work due to the blower being at lower boost than the turbo, It did pull 2nd gear cherpies with 33s, and was quicker with standard gearing and 38 inch tyres than my fathers stockie defender. All wrong in theory and all right in real life. It lasted 10000kms before i pulled it off the road to make it into a bushranger, but thats another story.
