Drop a tooth on the pinion and add some speedo timing. You should be in that 125 degree range. What type of lay out is it flowing or alot of 180s.

Pinion won't gain heat but the timing will. I still think you can fine toon more out of the motor thru speedo.

Sup Jeff thanks for your help at the Birds. Too bad I waited so late in the week to get the RS. Need some advice in general, at my home track we have what we call a horseshoe section because of the upside down U shape. If you do it right it is more or less full speed. my problem is the boost comes in really hard at the top and pushes the car out, any advice on setting or even driving tips would be appreciated. Profile 4, Timing boost - 45, and turbo - 10, ramp 2.0 start rpms 36xx to 15xxx.

Jeff, tried you setup on the small track this weekend (~55' x ~30'). I got it to work after going with heavier gear and bringing down the end RPM a bit. The end result, no difference in laptimes.

My current setup was for Duo 1:

- 0 motor Timing
- 55 deg Timing Boost
- 0 Turbo Boost
- ~2300-5555 Range
- 78-80mm roll-out range

The new setup after tweaking yours was:
- 0 Motor timing
- 45 deg Timing Boost
- .2 delay, 2 ramp
- 10 Turbo Boost
- ~2400-9000 Range
- 84mm roll-out

I initially went with no turbo boost this weekend but needed it for strait away speed. We have a sweeper coming onto the strait which makes full throttle section about 80'. Turbo kicked in right after sweep finished out.

The only benefit I could see between the setups was the motor was moved a bit more forward in the pod, which changed steering characteristics slightly. Otherwise same laptimes, same heat, both setups very similar drop off in laptimes (about .2 on this track & layout). The new setup a bit easier on the battery by about 150mah per run on average.

Just wanted to share the information.

im not jeff, but we have a section at my home track similar to what you have described, a double apex horseshoe. Depending on the turbo setting, it can kick in and push you wide. I combated this issue by rolling off the throttle half way around, so it would reset the turbo countdown and kick in after the apex.

I later found out it was just easier having a turbo delay of 0 rather than 1.5 which I started out on.

You guys running 5 or 6 minutes. Might have to lower boost a bit if your running 6 to control temp. I run a fan behind my motor on all my touring cars. I would run those settings without one.
Thanks guys....yeah, Hurricane series ran for 6 minutes. And I was using your setup at the last week TCS running 17.5 for 8 minutes...talk about getting "BOOST_LESS" after 6 minutes mark...(at least everyone does).

I will write them down and save that for the record..thanks again.

Whats your delay at and i have a similar section at my track and i roll off of throttle a bit before entrance of that section just to keep it off turbo. I run profile 5 all the time not saying that will help in this situation but worth a shot to try in general...

Try .1 and drop 2 teeth and raise the turbo to 15. Let me know how that works.

The problem with 0 on the delay its really ineffecient for the motor. It tends to build extra heat in the motor but really it comes down to what works for you.

You loose boost after 6 minutes?

Hi Jeff,

I had a similar thing happen to me sunday, It was weird the motor temp was no more than 60 Degrees C but in my last quali round my boost had noticably faded after the 4 min mark in a 10.5 touring car...Its never happened before! Any ideas?
Settings Motor (Speed passion V3) Geared at 7.00 with a straight of aprox 30meters
RPM Range- 27xx-100xx
Boost- 55
Turbo-10/0 delay
Proflie -5

My delay is at .1 but you have a good point about backing off the throttle since I am probably moving at a speed above what my old speedy would give me at full throttle.

Reprogram your speedo with the throttle epa on your radio at 95% and then bring it back up to 100%. Let me know if that helps

Yeah by rolling off i found that my times were more consistant.
