Renovation Time
Bryanj:
You don't need the oil cooler unless it's a realy heavily tuned motor or you are spending long times at high speeds on the motorway.
The above is for general consumption, as you say yours is an ex race engine it will probably be running hotter than standard and as such a cooler would be a benefit, if you can get a thermostatic By-Pass in there more the better

I've often thought about it but not been arsed to do it. I have this adaptor from its racing days just kicking about, and I have a spare cooler from my old z...Yeah I'm going to fit it anyway, if my bog stock Z needs one then this certainly does at 100cc more than stock with bigger valves, a cam and gasflow .
No doubt we'll be cruising the 125miles odd to Heysham at just under 100 mph, and it will be doing at least 1 lap everyday for a week in the IOM probably 2 between 5 and 6am. The bikes done the trip twice before as a 550 getting some serious stick when I was younger, and I haven't really grown up..!!! I'm going with a trackday R1, ZX10R, and a VFR850 vtec, they wont be hanging about. I just know the Honda is going to get thrashed to death, I hope it can keep up thats all, I mean the VFR of course.. ;D ;D

Get a (large coffee) and settle down to read this
;D

Holy crap...even I couldn't read all 35 pages of that..!!! I'm fitting it and thats that.. ;D Actually the Z cooler will be alot less efficient than my old much larger race cooler...which I also still have - the adaptor and cooler was all attached to the engine when i bought the engine back in the mid 90's. Anyway ..no debate necessary I'm fitting it....huh ...gotta get some new pipes..!!!
Right I've decided, I'm not fitting it....yet...but I will weld on some brackets for it.
My 460 and 600 engines used to run on Shell straight 40...lovely stuff...I dont know if its still available. 10 mins warm up and then thrash for race..the engines used to look spotless inside at the end of the year, with no apparent wear.

I had a Derale USA cooler fitted to my modified 750/823 F2, which looked like this...
...with the kit parts from http://www.derale.com/ looking like this...
...together with a seperate Lockhart thermostat which was the smallest one that I could find.
Lockhart did sell an oil coller with the thermostat built into it, but I already had the Derale by then.
