Default Engine Temps in 10.5T SC10

Just curious to hear some feed back on your engine temps in the SC10's..

I am pretty cautious of this in my other cars, and it seems that in the SC-10 no matter what i do, the temp always seems to be on the higher side.. (havent temp gunned it) but its enough for me to worry about..

Ran for 5 min qualifiers..

here is my setup:-

Fantom ION 3 10.5 turn (timing back to 0 on engine)
Spur 84T / 23T Pinion (supposed to be ideal on the
5600maH Fantom 65c 7.4V Pack
Tekin RS ESC

Have thought about trying to get a fan back in there some how??

Thanks for your time..

I would definitely grab some kind of temp gun. You can find them in places for as little as 10-15 bucks for a cheap-o. They might be a few degrees off compared to a more expensive model, but it will give you an idea of what you are looking at vs using your finger. The one i use most is a decent one i found at harbor freight for around $30. Seems to work pretty good and is off maybe a degree from some of the higher dollar ones some of the locals use.

I run a 17.5 to death in my SC10, temps usually around 150*F, a little higher in the longer mains.

I am actually getting better temps than i used to since i switched to the tekin rs. I gear lower and make up for the rest with boost. Im making less heat on the torque end, where the motor struggled more to accelerate..

I have run this same setup in my buggy, but the buggy has a lot less weight to carry. The motor in that comes off the track at a nice 95-105 degrees or so.

Might want to check into gearing lower and using some boost on the upper rpm band to get your top end back.

if you can put your finger on for a few seconds without a blister you are ok, 140-150 deg seems hot but if you have ran it that much with no smoked smell you are ok. It is normal to get hot, you can run it upto 160 deg without hurting the motor

Get a temp gun!

A motor can feel boiling hot to me by hand and still only temp around 120-130f. Different people have different pain tolerances and that includes how hot something feels to the touch. I can't wash dishes at the same water temp my wife does either!

Mine run from about 90 - 120 degrees on the motor , when the ambient is 70-90 degrees.

Default thanks..

Im hoping to get a temp gun off a friend for this weekend and try it then.. Will let you know what i find..

GizmoJunkie:- Here in Oz, the class is allowed up to 10.5T but no Boost , so the tekin has to stay in normal mode, only adj timing profiles..

Will have a play, was the first time i had raced it, so just being cautious

On my ft sc10. I'm geared at 81/19 at 150deg range. 84/23 seems a bit high to me. I do agree that a temp gun is a must. The peace of mind is totally worth the investment IMO.
