MMM interesting
You are wright in saying that the hottest place in an engine is the back oif the head.
So maybe thats why datsun put a water out let at the back of the Aseries heads to solve this problem.
My Aseries runs 10.6:1 comp standard radiator with a 10inch thermo & dosnt get over half on 40 degree day in traffic. With standard flow of coolent

I just got the head back today. Luckely only bent exhaust valves.
Still have to look at the bottom end. not looking foward to it.

You will be glad to no i think i have nocked them off by a second. I am waiting for the times to come up on the website.
And there has been small talk about a sertain engine (wink wink nudge nudge)

not to good
1 black black flag for noise & another for the bonnet rod hanging out the front. then the fatal error.
on the bright side i beat by own record buy 4 seconds Ran a 2.08 old trime was 2.12

We had a race at Phillip Island on the 23rd. Well i blew up the A14. I had a big valiant chasing me down but his staright line speed was a bit much for the ol datto. So i held it a bit long in 3rd. Well 8700rpm & missed a gear was the end of my day. The crank pulley ended up on the race track at turn 1,4 bent exhaust valves & i havnt checked out the bottom end yet. she will race again.

I have seen the tail shaft story on myth busters funny stuff. But they wearnt doing 200kmh

Go Aseries. there a little engine with a bad attitude when there set up properly.

I think $190 for a days racing & a licence (if it lasts a year) isnt bad value for money for someone that has never raced a car. One speeding fine will cost more.

Get your radiator fixed it wont cost much
Go & enquire before you buy 1

MMMMMMMMMMMM
I HATE drags but i might come along & spectate or have a run still thinking
MMMMMMMMMM
