Hi.
Have had the car finished for a while and decided to see what gains have been made.
The engine block crank rods is as it left the factory. I have added:
Tighe 805 cams with adjustable cam gears
Modified Alex Cowie cylinder head 10.4 compression standard valves eibach valve springs
4 into 1- 1.5/8 inch staggered length primary extractors with high flow cat and 2 1/4 inch exhaust
Cold air intake with heat shield
standard ecu
timing set at 14 degrees
Made 95.7 rwkw at 7000rpm-very happy with the result. No the dyno is not happy if anything its the other way.
The only thing which needs attention is the afrs so I guess a safc is on the cards.

Do you have a print out?

That's very good power for the mods performed.

I've heard of some ITB set ups making about the same power.

Hi.
I can't post the dyno sheet up until next sunday. The reason is I am not very computer literate and my son will do it for me and I will take notes. Sometimes I feel I have been missing a lot by not learning how to do these computer things. I must remedy this.

Do you know what the modified head flows? I'm curious to see how much other modified heads flow.

Hi.
I don't know what the head flows. I will contact Alex if I can tomorrow and advise.

Hi magpie.
Unfortunately the flow figures are unavailable.

Here is the dyno sheet.

I assume it's (primarily) pistons not a head shave that's given you the 10.4 compression?

Hi.
Compression is with standard pistons 30 thousand off the head and a 1mm maruha steel head gasket which is 10 thousand thinner than a standard gasket. So 40 thousand all up.

Was was the before mods number?
95 is good, how does she feel now out on the road?

Hi Weevil.
No numbers before as it is a long nose import motor which was described as low kms engine and a strip of the head and sump tends to confirm that. Drives good does everything a good motor should. There is no rocket science to getting reasonable power from these engines using the standard ecu and injectors. You live at Kariong don't you? The reason I am asking I visit my mother every couple of months and you are just up the hill from her.
Send me a pm with contact details and when I am next down you can have a drive.

Hi.
Have had the car on the dyno again to sort out the fuel and got 97.6rwkw a modest gain.
