Is this a certainty? I was under the impression that once a drivetrain was certified for emissions compliance, it was a full green light. Hence Lotus using unmolested Toyota drivetrains because they had already cleared EPA emissions testing.

Valvetronic and Vanos (single or double) are not similar in intended effect. Valvetronic is utilized to decrease pumping losses during low throttle/load. Under normal operation, the throttle body is disabled- with the Valvetronic system's continuously variable intake lift controlling engine output. This is NOT a…

considering that the SRT Viper puts out about 76 hp/L (highest specific output for an emissions compliant 2 valver, right?).....74 hp/L from the half as expensive base C7 is pretty damn good.

good one!

different engine architecture than the euros (or any one else, really), so the specific displacement argument is a bit disingenuous. Comparable or better power, torque, fuel economy, engine mass/volume, etc.

"and since poor people tend not to own cars, it doesn't have the regressive implications of a sales tax"

Believe that I read that this was VW's only non-unionized plant. The home country and much of Europe is very pro-union, so I would consider this catering to its own consumers as much as its home work force.

V50-R, V70-R...whatever the nomenclature is- R wagons with 3 pedals!

Too right!

the one that first addressed the SRT letter, didn't know it finally leaked.

That would seem to be the only logical explanation. Although Stubberfield did just teleconference with regional heads and reportedly was beyond intoxicated, so maybe logic isn't in the equation. Very surprised that/if the feds aren't already investigating a non-profit with over $million in revenue that clearly has…

bingo

Major problem seems to be that Chrysler has (heavily?) subsidized and officially sanctioned this not for profit organization for many years. From appearances, the for profit spinoff parts company has been siphoning the non-profit clubs revenue (including Chrysler funding) while becoming a competitor to MOPAR and the…

safe haven for BMX and heavy metal as well!

on the upside...consumers might realize how much power they're losing with an automatic or the big heavy wheel/tire of SUVs!

I didn't think manufacturers were required to post any output numbers (in the U.S.). I don't recall any gov't agencies involved with 99 Cobra, Miata, etc. that didn't produce advertised horsepower.

good example with the turbo GTI- many variables greatly alter output with forced induction, especially when aftercooled. Fuel temp,oil temp, ambient temp, underhood temp, fuel quality/characteristics, vehicle speed, engine load, and many other factors have a much more pronounced affect as compared to atmospheric…

boost in a turbocharged engine is load dependent....there's no way peak torque is at 1500rpm in lower gears.

Of course! more tech=more better

pistons don't come to a stop? isn't that where "reciprocating" comes from? are higher mass valves good for torque as well? How about driveshafts (they have kinetic energy as well once underway)?
