Additionally, the MP62 hits a pricepoint. The tooling is likely fully depreciated. Eaton is probably splitting the market into 2 tiers, high and low-end. They will have to pay for the TVS tooling AND they charge a higher price on the TVS because they can. Ultimately, the price is what keeps an intercooled TVS off the market. Lastly, you get to a point of diminishing marginal return. That is to say 10psi on an 11.5:1 compression motor is the practical limit on pump gas. The fairly horrid efficiency of the MP62 at that pressure ratio is compensated by the intercooler. The TVS is more efficient, so it doesn't need the IC to cool the air at that pressure ratio. Would it be cooler with an IC, sure, but not alot. Is 10-15 potential horsepower worth the loss of throttle response and the extra $1k-$1.5k for the IC setup? Undoubtedly a few of you will answer "yes". But how many people would at that pricepoint? Could a company make a business case for it?
