Weak points on turbo K20A3

[USAF EP3]

I would think that the reason that the power is greater down low is because the fake vtec begins at around 2800 on the a3, to get it moving.

It's not "fake" VTEC. VTEC = Variable Valve Timing and Lift Electronic Control. Doesn't matter if it's two lobe or three lobe or any lobe. VTEC is VTEC. Also, it engages at 2200 RPMS on K24A1/4/6/8 and K20A3/Z2. Quoted from Wiki:

"VTEC was initially designed to increase the power output of an engine to 100 HP/litre or more while maintaining practicality for use in mass production vehicles. Some later variations of the system were designed solely to provide improvements in fuel efficiency."

And yes, it makes power faster below 6000RPMS because the profile for the secondary lobe is larger than the primary lobes on the three lobe VTEC engines.

Also flips over at 2200rpms....

All that was repostings that were posted almost 10 years ago when the 02-03 Si came out.

I was joking. Most people think of vtec as increasing horsepower, not improving fuel economy. Hence the "fake" word.
