Done with break-in, want more power

Fujita is the stuff.

Thanks. Do you have the site?

That'll give me a head start for when I get my Lotus!

the IVTEC. I=integrated, which mean that VTEC runs more smoothly than regular VTEC. you feel more power throughout the whole rpm range. I have a AEM cold air intake system and it does not void my warranty. it's just more air into the car. and that along with a complete exhaust system you really do feel the IVTEC. I did a basic dyno when the car was stock. it had 187 WHP. not bad for a car that has 197HP stock, recently ran it on the track at 15.3

Was is a Mustang dyno? Those numbers see way off for depreation value/ drive train. Oh, and here is to your I=integrated.


[edit] i-VTEC
i-VTEC (The i stands for intelligent) introduced continuously variable camshaft phasing on the intake cam of DOHC VTEC engines. The technology first appeared on Honda's K-series four cylinder engine family in 2001 (2002 in the U.S.). Valve lift and duration are still limited to distinct low and high rpm profiles, but the intake camshaft is now capable of advancing between 25 and 50 degrees (depending upon engine configuration) during operation. Phase changes are implemented by a computer controlled, oil driven adjustable cam gear. Phasing is determined by a combination of engine load and rpm, ranging from fully retarded at idle to maximum advance at full throttle and low rpm. The effect is further optimization of torque output, especially at low and midrange RPM.

For the K-Series motors there are two different types of i-VTEC systems implemented. The first is for the performance motors like in the RSX Type S or the TSX and the other is for economy motors found in the CR-V or Accord. The performance i-VTEC system is basically the same as the DOHC VTEC system of the B16A's, both intake and exhaust have 3 cam lobes per cylinder. However the valvetrain has the added benefit of roller rockers and continuously variable intake cam timing. The economy i-VTEC is more like the SOHC VTEC-E in that the intake cam has only two lobes, one very small and one larger, as well as no VTEC on the exhaust cam. The two types of motor are easily distiguishable by the factory rated power output: the performance motors make around 200 hp or more in stock form and the economy motors do not make much more than 160 hp from the factory.

In 2004, Honda introduced an i-VTEC V6 (an update of the venerable J-series), but in this case, i-VTEC had nothing to do with cam phasing. Instead, i-VTEC referred to Honda's cylinder deactivation technology which closes the valves on one bank of (3) cylinders during light load and low speed (below 80 mph) operation. The technology was originally introduced to the US on the Honda Odyssey Mini Van, and can now be found on the Honda Accord Hybrid and the 2006 Honda Pilot. An additional version of i-VTEC was introduced on the 2006 Honda Civic's R-series four cylinder engine. This implementation uses very small valve lifts at low rpm and light loads, in combination with large throttle openings (modulated by a drive-by-wire throttle system), to improve fuel economy by reducing pumping losses.

With the continued introduction of vastly different i-VTEC systems, one may assume that the term is now a catch-all for creative valve control technologies from Honda.

This was pulled from a fast Google search which lead me to.

i-VTEC is just VTC + VTEC, old style VTEC is still present, and you should feel it, I've never driven an i-VTEC car (unless my dad's 05 v6 accord has it, but thats an AT) so I wouldn't know how much it kicks.

VTEC changes timing by changing the cam profile. I-VTEC does it in 2 stages. Regular VTEC advances 50 degrees all at once, I-VTEC does 25 then 300 RPMs (if I remember correctly) does the other 25 to reach 50 degrees advanced timing. By using 2 jumps it makes it easier on the valves.

wow AP1fun you know a lot about this. how do you know so much? and your only 17, (your profile said)
