But it really requires some finesse, and might be beyond my current skill level to do it predictably enough to be worth it.
The last few pages have shown that many of us are coming to the same conclusions.
I run on a short track (1s 1/12 17.5 Redline) 50x25 with a sweeper entering the full length straight (Very slow chicane prior to the sweeper, motor is probably under 1000rpm). There is "room" to be on WOT for around 60' before getting off the throttle for a 180* turn. With Timing Boost @50 (1425 start & 6000 end) I had Turbo set on ramp 3 and 0.7 delay initially. I couldn't feel the Turbo kick in and got a temp of just under 160* ( I was bogging down the motor with the Turbo). I moved the delay out to 0.8 and could obviously feel/hear/see the Turbo "hit" and the temp went down to 132*. Problem is, the Turbo was "hitting" just as I was getting off the throttle for the 180* corner and it ended up pushing me out and off my desired line more than it helped me in any way. I had to feather the throttle to "reset" my delay, in order to keep my line tight.
My thought is that with Timing Boost available up to 60, there is no way a 1s 17.5 car can "use" 50* + of timing advance in less than 65' (obviously dependent on gearing and track layout). When you run on a larger layout that may be helpful information. A delay of 0.8 will "hit" the Turbo at around 60' with a Timing Boost of 50 and a Rollout of 76.00mm
On my small track, I will be running NO Turbo and it works great. I'm only able to use a little more (5*) total timing than with v200 but I have better Low and Midrange throttle response, which helps with passing and general driveability! My fast lap with v200 was 6.925sec and with v203 was 6.889.
The though thing to admit is that "extra power" does you no good if you pile into to boards - all is lost.
The truth about most of us club drivers is that on a big layout, we can probably use Turbo and have a larger grin between accidents. On a small layout, there is not a huge difference from a well tuned v200 car, just a little more responsiveness. That alone is a good thing for those rare occassions when we get a solid "clean" run.
