Seriously....because the turbo will be at its limit right off the bat. Will it make his goal? With out a doubt. Will it be efficient? NO! Will he need bigger injectors? I'll bet on that too. Why because of the heat that its gonna generate (efficiecy) he will need more fuel as a band-aid.
Not knockin his build..I love turbo cars! They are a lot easier on parts to maKe power than any other power adder on the maket hands down! Cheapest? NO Effective? Absolutely!
