Ideal shift points work out as;

1-2 shift @ 7500rpm
2-3 shift @ 7000rpm
3-4 shift @ 6600rpm (if needed)

But no way am I shifting over 6500.

So on each shift @ 6500rpm my rpm will drop to;

2nd = 3846rpm
3rd = 4482rpm
4th = 5078rpm

So my average HP through the quarter mile is going to a lot less than the peak HP shown on the dyno sheet. Meaning 11.8 in the quarter is unlikely unless I am making more power than that.

That's fascinating stuff Dave, obviously a bit more than just a template porting job on those heads!

Oh yeah.

Here are flow numbers for a couple of other popular heads;

Stealth/Eddys
.............IN...............EXH
100 --- 65/79 ------- 57/70
200 --- 135/143 --- 108/126
300 --- 191/207 --- 140/160
400 --- 227/256 --- 159/188
500 --- 242/278 --- 173/206
600 --- 254/291 --- 183/217
700 --- 261/292 --- 191/223

My 906s
0.500 --- 258 ------- 201
0.550 --- 262 ------- 204
0.600 --- 258 ------- 208

Don't know where you got the flow numbers from for the Eddy's but these are what I have seen.

.1 79/70
.2 145/126
.3 209/160
.4 254/188
.5 278/206
.6 290/217
.7 292/223

I see what you've done now, the columns are in the wrong order.

You are right Mick.

I wonder where i got those from? I thought they seemed low.

Here are some better flow measurements.

Ah!

I think they make sense now?

Anyway. It shows my Hughes Stage 1 ported iron heads flow just very slightly better than a pair of un-ported Stealth heads.

Took her out for a test drive earlier. Not had her out for weeks due to bad weather every time an event was on.

Only been out 5 mins when I got into a traffic jam due to road re-surfacing. Then I glanced down at the temp gauge. It was reading 220 degrees.

After swearing out loud I managed to get the car turned around and parked up out of the way of the traffic so I could pop the hood and have a look.

It was just the ground wire for the electric fan had pulled out of its crimped on spade terminal. I jammed it back in and managed to get back home without it coming apart again. The temp was back to normal by the time I got home.

I was only out 15 mins in total.

Going to do a few checks on it tomorrow night to make sure all is well and then take it out to a cruise on Wednesday night.

Is that the Silverlink cruise?

yes rich

It will be nice driving along the sea front this week with it being so light and warm.

What is the 'normal' temp, Dave?

I have it set at 180F +/- 5 degrees which is what the thermostat is rated at and is a good compromise between power and wear.

I think standard was 195F for a lot of these cars?

Found another problem today.

Looking at photos of my car (like the ones Dave McBride took) the car looks to have a lot more negative camber than I remembered dialing in.

Finally looked into this today. Indeed it does have more negative camber.

Found out why. The bolts were not tight enough.

Put it right now.
