Replying to: mtbrider (Oct 04, 2006 5:56 pm) A turbo has to spool up from exhaust gases before it supplies power. Larger turbos not have any appreciable power below 3,000 RPM. Some newere smaller turbos and twin turbos will spool up faster. VW has gotten 90% of Hp as low as 1,800 rpm, but this isn't typical. VTEC used to be twin cam and there was a dramatic power increase arounf 4,500-5,000 RPM. New VTEC is a continual change of cam and the affect is very linear power increase with RPM increase. To drive a VTEC sporty the RPMs need to be kept high. However as opposed to a turbo where you typically have a .5 second turbo lag if it is not already spooled there is no lag with VTEC. Having said all that the STI is a different beast altogether. With 300 Hp there is a lot of horspower there! Even without the turbo there is a substantial amount of horsepower as compared to the standard WRX and most other turbos. Having said all of that, I like VTEC better than turbo by far. I had one turbo and that was enough. I have had many VTECs two Hondas currently and an IS300 which uses the same principle. To run properly a VTEC needs a manual transmission. Good Luck in Understanding, Cheers, MidCow

Replying to: mtbrider (Oct 06, 2006 5:55 pm) The Si is a reasonable daily driver. It gets good fuel economy, has a fun feel, is throttle responsive and handles reasonably well. The STi gets horrible fuel economy (I averaged 15 mpg) and has a turbo lag of greater than one second unless you pop (and wreck) the clutch. It has great cornering and high speed stability. In my opinion, the STi is strictly a weekend car.

Replying to: john500 (Oct 07, 2006 5:43 am) Are you sure you owned an STI? From your description sounds like you had a regular WRX. I have to tell you ...the STI is a completely different beast. It has INSTANT throttle response and due to very close gearing is ready to rip anytime your foot hits the gas pedal. P.S. Fuel economy ??????????????

How come there is no talk of the Car and Driver article in the Nov 06 issue, where the Si's holy pedestal is taken down a notch? Comments on the Si included "weakest breaks", "breaks that faded greatly after 2 laps", and "floppiest body motions". So much for the fun to drive factor. With its gearing, it only managed to beat an MX-5 around the track. All cars were unmodified production vehicles equipped with all the performance options available.
