Type 1 Engine temperature specs

This is for a stock T1 engine


NORMAL ENGINE OPERATIONAL LIMITATIONS

Engine Idle RPM 600 - 800 RPM
Cruise RPM 3200 +/- 200
Maximum RPM 3600
Minimum oil temperature 160

Where did those come from? I don't agree with some of them, but that's why they make chocolate and vanilla...

Those specs sound like for a Type I 1100 cc engine I know VW rated the 1600 at 4500 RPM's

During my 30 minute cruise to th einspection station my oil temp read 200-230, most of the time it was 4 lane 60 MPH around 3000RPM.

Should I be thinking of an external oil coller?

Where is your sending unit? I originally had mine on the oil drain plate which was (of course) on the bottom of my deep sump. Motor always seem to run cold. I've moved it up to one of the pressure valve locations and it runs a lot hotter and much more accurate.

Damn, That puppy is hot as a firecracker......but stock engines run the hottest! Thats what my dyno has told me...

The sender is installed in the rearmost pressure relief plug.

Hey Jake,

Any free advice? Oil cooler, more openings in the deck lid, differnet fan shroud? Whats the best bang for the buck?

Thanks George,

I'll add that to my list of "Winter Projects".

John Steele (JPS) sells engine lid "buttons." What you do is remove the rubber gasket around your engine lid and install these buttons. While it won't cure a heating problem per se it will allow more air into the compartment so perhaps it will help. Inexpensive and easy install, too.

Best bang for the buck unfortunately requires removing the engine to cut a 3" or 4" diameter fresh air inlet vent in the firewall directly opposite the cooling fan inlet. It should be screened, can have a pickup scoop added to take the inlet low, and should have some method of closure (won't be required during cold weather).

IM's come with rear deck lid buttons (no gasket). Original Speedsters did not have rear deck lid gaskets.

I am using the buttons, thanks to other discussions on this forum.

I was able to cut a hole in the "firewall" opposite the fan today. I didn't have to remove the engine and tranny. I used a dremal tool with a cutoff wheel and was able to nibble out a nice hole.

Now I have to work up some ducting, I think I can do that without removing the engine also.
