Front & Rear Nudge Bar Fitment & oil temp sender

[kdavies3]

Team,
I remember reading a string some weeks ago re; fitting of front and rear nudge bars to a Dax Tojeiro. I've searched and can't find it for love nor money.x(

Can anyone give me a pattern as to where to drill the holes in the front and of the chassis outriggers, as it's obviously a lot easier to do without the body on.

On a completely different tack, what's the general consensus as to where to put an electrical oil temp sensor on a small block chevy. (I don't want to remove the sump to weld in an adaptor). I know that the sump is where the hottest oil is but the gallery oil is what's being pumped around the engine post cooler etc.
I guess the choices are gallery plug (above the filter)or at the tapping at the rear of the Vee along with the pressure switch and gauge.
Your thoughts please.

cheers

Kev - if you can't find a suitable place for your oil temp sender (is it mechanical or electric?), you could always fit it in the run of hose back from the cooler, thus sensing oil temps as supplied to the galleries.
Mocal do a little ally housing you can fit in the oil hose run.

PS the reason I asked is it mech or elec, is that for the mechanical guage, the sensing bulb is too large to fit into the block anyway - it has to go either in the sump or in the housing mentioned above.

Thanks for that Wilf,
I think I'm sorted I'm going electrical using a Smiths gauge and sensor matching the rest of my instruments, Gower Oaks can supply a thread adaptor to go into the oil gallery hole over the filter (1/4" NPT), as well as the gauge etc.
I still haven't made up my mind if I'm going to fit a cooler straight away or fit one later if I find I need it.
Mostly road use! but I may have to join some of you basket cases on the odd track day and runs to Le Mans.}>

I don't need no track to make my oil hot!!! }> }> }>

("basket case"????)

Ye, but has she cut her fingernails yet?

Mike - you've been skipping your medication again, haven't you??

Wilf,
I'm no Sunday driver and I know I'll get worse with the Cob. So are suggesting that I'm going to need a cooler for road use?

(Basket Case - remove brain and place in basket in the boot, start engine etc.)

Kevin,

1, If you talk to Dax very nicely, they may lend you their templates for cutting the front holes fro the nudge bars.

2, Oil temp sensor.

You will not get any sort of realistic reading by putting a sensor into either the block or the pressure sensor take off adaptor.

It is however quite easy to drill and tap your sump plug, screw in sensor and attach the wire.

This works fine and gives you the actual temperature of the oil in the sump.

Kev - here's my logic:

Oil temp control is fundamental to the health of your engine
You are stuffing a fairly large engine into a relatively small space with very uncertain airflow around the engine.
The cost of an oil cooler installation is low compared to the cost of your engine.

Soooooo......... I guess I am saying you should fit one. On hot days, after an "energetic" road drive, my engine is glad of the cooler. On a track it is essential (in fact I need a bigger one). Oh - and fit a thermostat. Too cool oil is as bad as too hot.

MHO as always
Wilf
