VTC angle

[aaronng]

That is a pretty nice gain there. Torque gains all around. Is the before dyno fully stock? Or is that with header and exhaust but without unichip?

[Aslam]

The before dyno is as stock as they come

Revival to this thread...

Has anyone successfully had their VTC mechanism machined to 45 degrees??
If so, how much did it cost, and what were the power gains??

cheers

just found this on heel toe

rsx-s vtc actuator...
Would this be 50 degree?
pretty cheap...

[npcan2]

yeh, its 50degrees. *sigh*

[EG5]

We used 50 degree vtc too on our egk24a. Too bad we didnt do comparison between 25 degree vs 50 degree VTC.

[oongie]

why sigh at 50 degree?
Kpro your engine to max out at 45?
Dont overrev and you should be fine! Much easier than machining your 25 degree vtc actuator!
Yonas, the 50 degree actuator and KPRO should be enough to net awesome gains?

[integral90]

the 50 degree actuator and KPRO should be enough to net awesome gains?

Yeah, big gains

[oongie]

Might be an idea to get the 06 tsc cams as well...

[npcan2]

What kw gains are you looking at with K-Pro and 50deg VTC with I/H/E already installed?

[oongie]

dunno... more torque...?
I remember reading about Yonas's EGk24 and with the VTC advanced the engine made something a real dramatic difference

[Quest]

Has onyone successfully managed to address the FULL 25 degrees of the VTC with your piggyback ECU? As far as I know (Hondata comment), only 20 degrees is addressed by the stock ECU....There's an extra 5 degrees to play with....

"The stock TSX ECU limits the cam advance to 20 degrees. (even though the mechanism is capable of 25 degrees)"
