Recently finished my 1904cc build and got it in the car. Runs great but the oil and heads just aren't getting up to operating temp. Should I be concerned? The jetting is close (not perfect yet). timing is 10/30 with the 009. Engine specs below.
1904cc 74 x 90.5 balanced
Aluminum super case
043 heads 40 x 35 p&p
52cc chambers, mirror polish
.038 decks
9.2:1
running 91 octane
26mm Schadek full flow'd
Gibbs HR1 15w50 conventional oil
dual Weber 44idfs
1-5/8 stainless sidewinder exhaust
compufire ignition
I cannot get the oil over 180F degrees and heads over 250F. I have had the VDO senders and gauges for a while and have worked is the past. The CHT sender is under #3 spark plug, the temp sender is at the rear pressure relief in the case. |
your oil temp is nice, I like 180F, the heads are way cool, could it be it was a hot day and your thermocouple on the heads is reading low because of the high ambient temperature?. Remember the head temp thermal couple reads higher as the air temp at the gage drops, and visa versa, as the air temp increases, the age will read lower.
what is your air temperature?

ok, time to make sure your calibrated, if you can bring a pot of boiling water o the car, and knowing your boiling point, you can check the gage calibrations. a camp stove will work to boil some water at the car, then dip the sendors into the water and read the gages.
The gages could be way off, I hope your oil is ok, I would be happy to have 180F oil.

So I just took the car out for a 30 minutes and hammered on it the entire time. It's about 65F ambient air. The hottest I could get the motor was 200F oil and 250F CHT. BTW. I'm loving this 1904. Car hauls ass. If y'all think these temps are acceptable then I will just leave it alone.
I will calibrate the guages as suggested.
Thanks again for the help all. |

I wish I could get my oil up to 200 Degrees.....
I'm lucky to hit 160 degrees.
I think I might have it fixed now though,

I would be tempted to drop the timing down to 28 deg and see how the temps react
