My motor leads a hard life.
It is my first 911 motor build and other than machine work and the heads, I dodit all meself.

It gets driven little, then with minimal warmup we're off to AX. It is seldom up to full operating temp for the first few runs.....I gotta find a better way to do that. Then it gets to bounce off the rev limiter as we search for gud shift points. Then (maybe) the 7300 chip goes in.

As part of the winter project, adjusting the valves was part of the sequence. It ran all season on one adjustment done about this time last year.
All 12 of the valves were .001 loose......amazing. No rocker shaft creep, lovely even wear on the cams.

I got the cam break in right, if nothing else.

Hey JP,

Find a way to get the engine to good temp before you let it rip
If you don't you'll wear it out fast...
If you do, it'll take the abuse and ask for more (IMG:style_emoticons/default/biggrin.gif)

cheers,

Jeroen

How about a prewarmer? They (FLAPS) used to sell "block heaters" for bugs, way back when. If you have a 110V power supply, plug it in to warm the pan.

Jeroen: No shit? (IMG:style_emoticons/default/biggrin.gif)

Part of the problem is that I worked at making sure it runs cool. Now, it takes about 15-20 minutes of driving to fully warm. I do this by taking the long way around to get to PIR......then it sits while I do course set-up & stuff. Last season, I also set-up the staging lanes, got folks where they belonged and then ran the second run group. So, about 3-4 hours later, we fire it up.

I'm thinkin' bout laying a towel over part (or most)
of the engine grill. Just setting there idling won't get it warm. I did this once with a 911 and it did the trick
fairly quickly....bout 5 minutes....but I dunno????

But your 914 HAS TO HAVE A OIL COOLER.. (poking fun at JP)

We drove the 3.0 9146 hard all day Sunday at Laguna Seca and the needle never moved off of 120deg (this is not good) I should have blocked the oil cooler off. Day time temps where mid 70's and sunny.

Block the engine lid like you said and block off a portion of the oil cooler. This way when the thermostat opens... it doesnt imediately cool the engine back down.

EH?
120? Iz'at Centigrade, Fahrenheit?....Kelvin?...nah.
Sounds bad to me in any case (pokin' fun at Brad). Surely you don't think it's 120 F. (IMG:style_emoticons/default/cool_shades.gif)

The engine mount thermo opens at about 175F.....and is "throttled" so It doesn't cool off the motor again.
Full open at 212F...same same with the ex-cooler thermo....at least that's the way mine works.....dunno what yours is doing (IMG:style_emoticons/default/blink.gif)

I'll just go with the engine lid towel, thanx

Dad you know I never had a prob getting it to warm up, just take it to about 130mph and that shoud do the trick. You know if I were there I would take care of that for you. (IMG:style_emoticons/default/happy11.gif)
