Engine Block Heater

[gtrp]

Googling didn't help too much, but are there any good engine block heaters for a 911sc so I can have things warmed up before going for a drive?

Or an oil pan heater?

I'm just tired of cold start issues so figure if I never drive it cold, it'll go through a lot less wear

If you are a DIY, you might be able to adapt a tank style heater to work in the 911 oil tank. Industrial supply stores might have something that would work, but it would have to be able to survive in hot engine oil. But, the bigger picture is what kind of temperatures does your car experience? Even those folks who live in the frozen North usually keep their 911's in garages that don't get all that cold. Multi-grade oil pumps well at pretty cold temperatures, so is there really a need for an engine heater?

I'm in Texas and switched to 10w40 oil, but the car is still so sensitive before it's fully warmed up. Maybe I'm not just used to this car yet.

Seems to me a tuneup and complete checkup of the CIS might be in order. A 911SC should be able to start up from cold and run well without being unusually sensitive.

Preheat isn't a bad idea, but these cars were made in Germany for less than tropic conditions.
Idea:
Reiff Preheat Systems aircraft engine preheaters

Thanks. I'm trying to retune it but it will still refuse to start some days when cold, other days it'll just stall at lights or bog while driving. When warm, it's a perfect quick car with no issues.

When I say cold, I mean a mere 60 degrees in the early mornings.

jmo, it sounds like a issue in your start-up between your fuel and ignition. The cold start circuit (choke) isn't preforming properly.

A small space heater under the engine would do.

Not the best pictures but we put on in the race car it has an electrical plug that just pushes into the silver fitting.

definatly a problem that needs looking into.

Sounds like an issue that needs fixing. Get a set of guages and go through your CIS settings. sounds like cold WUR issues. especially if it bogs at a light. when cold .
fuel pressure may be wrong for driving conditons ( engine temp )

[gtrp]

Thanks everyone. I'm definately going to get a set of gauges bc I don't want to take any shortcuts but sometimes I find my entire garage empty and need the 911. Was looking for a good backup solution. MJHanna, that's very very interesting!

Fix the starting problem........no need for an engine heater.

I agree you have a cold start issue that needs to be addressed, but you can add one if you want to, put ours in to reduce wear on the engine during start up and helps get the engine temps up quicker for the race.

60 degrees is cold? as above there are other issues

[jmpowers]

I've used this while living in KS. Works like a champ!

GTRP,

If you think 60°F is cold, wait till you get frost on your windshield and start the engine on the first try. I live outside Philadelphia where the climate is much colder than Texas. A properly tuned and maintained CIS engine would start regardless of weather. Check your fuel pressures (residual, control, and system) and any significant sources of air/vacuum leak if you want your CIS to run well. Keep us posted.

CIS was used on Volvos for several years, so it was meant to handle Scandanavian winter temperatures.

In the 80's CIS were also used in Mercedes Benz, Saab, BMW, etc.
