Im in for next time too keen to see how she go's with the switch in fuel :)

Im up for dyno day and possible drag. Just want to try fuel return line first in set up

I would be, hopefully I'll be able to make the next one.

Well done guys, looks like a good day out! Would have been there too if my gearbox wasn't broken. Would you be up for it again in a few months?

Probably should do another dyno day first.

No e85 carby.... means rebuilding them and all seals for e85. .. ewwww cheaper to go efi

That unfortunate noise is the fuel pump, it's a Holley blue that has been regulated back to 4.5 psi and there's nothing between the body and the pump mount so it is very loud. One thing I'm not short of at the moment is fuel flow, I was thinking of removing the pump and going to a facet pump but it might be best to keep that pump and bleed pressure off through a return line. Not sure,where I'm heading. The thought of E85 has crossed my mind.

Yes his pump is noisey in the rear.

Crumb, if that rattling all the way through your video is the fuel pump, it sounds like it isn't getting a good enough head of fuel to me. I had a small facet pump on a 1200 wagon a long time ago (1994 or so) that did this, it wouldn't rev as well as it should have, (A14 with 70 degree cam & twin springs & a 32/36 DGV weber) that wouldn't break into the 16's at Eastern Creek street drags, it'd run out of revs at about 6000 rpm. Was doing 17.0's all night.
Re-read the instructions for the fuel pump the next day & found the fuel pump should be mounted at a 45 degree angle. After remounting it the motor went straight round to 7000 rpm, like it should have. Never ran that car again but it was appreciably quicker to me. This might be the way to break into the 13's. If you have the facet pump like they use in the series 2 B/Bird, it has to be verticle, not horizontal, with the fuel outlet above the inlet.
There's always the posibility that Im wrong, but all my mates Hillclimb VW's used the small square facet pump & they all had to be mounted at a 45 degree angle with the inlet lower than the outlet. This was enough to set class records in the under 2 litre 2E/3J club car class in various cars, & win 2 Australian titles in that class.
We always measured the fuel flow & it had to be 2 litres or so per minute or the flow wasn't enough. We just stuck the fuel hose into a 600 ml bottle & ran the pump for 15 seconds. If it went close to filling the bottle, it was flowing fast enough.

Sounds like plan. Need to replace my axle and might try welding a 3.9 diff center and see what happens. Find out if I can get the 13.99 I was trying for.

Got a button clutch now so keen to change it and head back out to try to get in the 12's
