The new engine combo seems to have worked pulling mid 13's down to 13.36.
Problem was could not get into 3rd gear quick enough (FMX auto) causing over rev, trannie holds 2nd at 90mph??? Tried adjusting vac modulator to no avail!
Could have pulled better times down to 13 flat if I had 3rd!!
Smoked every maloo's & SS's I ran.
Just proves you can do respectable times with a budget rebuild.

i was out there last night in my capri and it was very hot and humid,your car would of went close to a 13.00 if it was cooler.my capri was two tenths of what it usually runs.

Is the kickdown connected ,if it is try disconnecting it.That is a good effort.What is your setup?and do you have any pics?

northiam

I saw you go! The capri is awesome, quickest car there you were!!!
Next time I'II say kuddah.
It was hot that night, but does the humidity help or hinder?

northiam

No kickdown connected! Got me stuffed!

Specs are:

ACL race pistons .020 oversize
Zero decked block
302 2V closed chamber heads, 2V valves, some unshrouding, polished chambers, mild diy porting, hardened ex seats, 63 cc chambers, crow dual springs.
Crow 61626 (F238 cam eqv) (solid)

Better result than I expected so I'm happy. With cooler conditions and 3rd gear maybe high 12,s

Well done! Was the 13.36 with a ~90mph terminal speed? It'll be interesting to see what happens when you get the gearbox sorted out then.

Might have heated up the trans fluid too much (boiling it). That would cause a flare. My prior 4 failed C4's have educated me in what to look and listen for. I would have prefered a properly build trans like my current one 1st up though.

Might also be a good idea to get the line pressures tested, check transfluids not low and also check vacuum. I've had a trimatic do the same due to a large camshaft. Wouldn't change gears till 7500rpm! I actually took the box back under warranty. They sorted it and the box failed again. The sorted it the box failed again. the replaced it, I walked over to the Holden wreckers accross the road and swapped it for a reco M21 4spd manual. Problems fixed I vowed never to use that company again and/or let anyone else use them too.

Heat and humidity affect your engines performance. Heat by making the air less dense and humidity by taking up the oxygens space which increases the relative altitude.
ie 35 degrees with 60% humidity and a low barometric pressure will equate to a relative altitude of 4,000 to 5,000 feet
16 degrees with 20% humidity and a high barometric pressure (1030 hpa) would equal approx sea level and if your cars tuned for it, it'll really go.
the more oxygen the more fuel you can burn = more power

There are calculators about which will give you a relative altitude if you've got the 3 parameters.

No, terminal speed was 104mph did eventually get into 3rd by laying off the gas then stabbing it again and again. I must have lost half a second f ing around. I had a new GTS or (R) skyline reeling me in top end due to this problem, but he didnt catch me hehe.

This topend problem is difficult to sort out as I cant easily/legally drive up to 90mph.

Not bad mate, but I'd be worrying more about that flat battery, eh? Can you imagine the embarrassment?

Will come and say hullo next time.
