Tb42 duel fuel carby issues

[dom14]

bohall, I could give you the setting I had my GQ on - but it would do you no good, unless yours was set up the same as mine................
and I spent a lot of time and a lot of money on mine
electronic ignition
modified distributor
port and polished head
inlet and exhaust ports machine matched to the manifold and extractors
and other bits and pieces

I could freely rev to over 4500rpm
at Wanneroo raceway best I could get (dont forget a GQ is not light) was 155km/p/h on gas
I could freely spin the rear wheels on a dry bitumen road - or car parks as was the want with 33's on, and even better when I went back to 11R's (32")
I had mine tuned for Race Performance on Gas (as it spent 95% of its time running on Gas )
it sucked dogs balls towing - fuel economy was real crap when towing, but would humm along at 100 without a problem - as long as there was no hills

Hmmm! What was the reason you couldn't get more than 155km/h?
Was it the road condition or the engine couldn't be revved high enough to produce enough power to go above 155km/h??!!
On normal flat highways(if you do), 155km/h is easy for a GQ within seconds after take off.
I'm guessing Wanneroo raceway hasn't got enough long straight stretches to reach high speeds?!
