Same here five minutes and I get full timing plus. I did find that one of the motor screws was stripped and had to retap it. Also not a big deal, but would to have expected it from a new motor.

So I race outside in sunny south Florida, are saying that this motor is fine at 190 degrees? I've been trying to keep mine around 170-180 and am not getting the power I thought I would have. Should I bump the timing up?

Also have you noticed a quick dump of power after say three or four minutes?

I like to keep mine at 160-175 degrees but 190 is not uncommon in the heat....make sure when you temp your motor that you find the "hot spot" ....move the temp gun around and find it...once you do find it, make sure you take the temp in the same spot every-time.....further more don't use a sub-standard temp device....check it by sticking it in your ear (I know sounds funny) you should come up with ....98.6 anything else and its off....you could subtract or add to make up for the discrepancy....just make sure it is not too far out......

Not all temp guns will fit in your ear though :-P

I use an automotive temp gun for temping header pipes, it wont mesure human temp accruately as the head of the gun wont fit in your ear, however it is accurate and reads up to 700*

If after 5 mins your noticing fade and you dont have power I would suggest testing your temp gun agenst a known working temp gun. It sounds to me like yours is off or your not temping the right spot of the motor. I'll bet if you gear down a few teeth you get the pep back you were looking for and your just as fast on the straight. I've noticed with the Duo series of motors you can over gear them a little and they wont get too hot, they just wont preform. I gear mine for about 130-140 and notice thats where they preform the best for me

I see that the D3.5 is available once again at the Trininty website. Are these the good batch or still the defective ones?

Furthermore, even after using the dremel on my existing motor including sanding the cover to allow for timing adjustment, will I encounter problems at ROAR events?

Does Trinity have any plans to address this issue with people who purchased the first batch of 80 motors or is it simply tough luck for early adopters? I have sent an e-mail via their website and still no response.

Sounds like the batches should have shipped today. According to the boys at Superior the timing is fixed.

Sounds like I should have one in my car for Sunday Racing.....

I am in the process of going through all the motors I got in today and dyno'ing all of them. I can tell you that what Ernie posted on his FB page about the timing is not designed to go all the way up to 40 degrees is true. I turned the first few all the way up on the dyno to 30 degrees and they were not very good. Way over timed and had a ton of RPM but not torque. I played around for an hour or so with the first one and finally settled on 20 degrees. It dyno's really good in that area. looking at the way the sensor board is mounted it has a lot more timing built into the motor than before. This is why I think they dont go all the way up to 40 on the endbell. Cant really say why they decided to put it on there but they did.

This is just an FYI for the guys that have been asking about it.

Anyone know if these have been roar approved yet? We have a race in a couple weeks and don't want to waste money on a motor we can't run.

No...I dont test with any timing in the speedo. I use an old LRP that was before timing came along. Timing is too hard on a slave motor/load dyno.

How have they been testing vs revtech, reedy, other stuff you have around?

They are about the same on the dyno as the revtech but make their power at a lower RPM and timing level which means they should run cooler and pull harder off the corner.

Also I have a couple left for anyone interested. [email protected] for questions
