Furthermore, and more importantly, you are converting inches cubed to inches squared simply by dividing by a unitless number. This does not make any sense at all with dimensional analysis.

That being said, the rest of the stuff is great. Thanks a lot for putting this info together.

]]>The GT-R can looks like “boring” no manual trans, everything is under a electronic, but for unbelievable heavy (3800 pounds), they made the car faster than a lots high-expensive cars and half-priced. Then some authors (who drove a GT-R) said that the GT-R is normal car, when you drive daily there are no pushing for a speeding, in low speeds. When you drive fast the car goes alive and the car feel mechanic, not electronic. ]]>

what’s about sequential twin turbo? You wrote it is difficult to make it. I know it takes long time to write it, but I am REALLY interested in it. It is a great set up. How should I make one? What is the math formulae like? Where can I find it.

I am interested in it, because I would like to have daily car, that can be used for hard race. I mean 800hp and 8000RPM (Nissan Skyline GT-R 34 with an engine RB30DETT (head RB26DETT stage 3) – standard is RB26DETT).

Thank you

]]>Given the overall quality of your information, I would gently point out that the above quotation contains an obvious typo:

2110 lbs{960 kilos}/300 hp = {approx.} 7.033 lbs per hp: Not 3.2 lbs per hp.

A power-to-weight ratio of 3.2 would yield:

2110 lbs{960 kilos}/3.2 = 659.375 hp.

I enjoy your very informative articles…keep up the good work.
