holley black

same as holley blue (14psi) but higher flow

what sort of fuel pump are you running?

And yes you should have the fuel pump mounted below the fuel level, but sometimes that's not possible?

yeah im running synergy (same as optimax), i dunno what pining sounds like really i hope not, did you alter the dizzy in the first place?

thanks ill turn em down and see what happens but i need to chuck in a new head gasket first, otherwise the cops will be able to catch me just by following the trail of smoke

actually the exhaust rattle only occured when i backed off, its gone now

one other question, where did you mount the fuel pump cause i have mine above the tank but in the first place i had to let it hang and run it, to get the air to come out of it, it wouldnt push the air out when above the tank. Im thinking air may slowly build up again, if say i go round a corner and the fuel surges away from the pickup in the tank.

Hey RC get a screw driver and slip off the little 'c' clip on top of the wastegate where it goes into the exhaust housing, slip off the rod and wind it out 1.5 turns on both turbos, that'll drop the boost down to 6-7 psi then itll hang on better,
what fuel are you running in it?
I allways ran optimax in it, dont know how much difference that made butits not much dearer.
Can you hear it pinging under boost? That exhaust rattle you spoke of eariler wasnt pinging was it???

If you havent altered the dizzy and are running good fuel in it, it shouldnt be

Are you at the flow limit for the needle and seat. Mixture check needed to check for lean out. Also could the fuel line need a size upgrade to allow more fuel flow.
Sounds like fun! even if a bit dodgy

HEAPS, i got it up and running again tonight and it tonks!!

but i need to do head gasket, she leaves a good trail of smoke and bubbles through the radiator a fair bit

it was a lot of mucking around with 4 of us working on it but finally got it good with a bit of hole elongation and other dodgey stuff

it seems to want to make more and more boost (gets to about 10psi) and at about 5500 revs it just cuts out like the fuel is not getting through anymore so im going to have to figure out how to turn the turbos down and see if that helps, fuel pressure is 14psi, and supposedly my bov is 7psi but i make upto 10psi, i dont understand how that works

And if it goes bang, well theres another hundred dollars and a bit of time down the drain. Cheap compared to an SR or CA blowup

I have been getting inspired by the low cost turbo formula. I wonder how much you can get out of a stocker engine with a little puffing

Yes I couldnt agree more, but this set up was built on a budget the engine is compleatly standard, even down to the staandard carby and points dizzy, yet will still blow away a standard VL turbo.

It HAS proved to be reliable, it has been to the drag strip several times and compleated 10, 15 second passes in one day with out a single engine problem.....from a internally standard engine....what more do you want???

and as RC said I played with this combination b4 going to a ca18 just for a bit of cheep fun

Funny the similarities between pumps and auto engines. The main difference is that the reciprocating high pressure pumps are built much stronger than auto engines.

I bet the use of O rings and gas rings in engines came about from some pump repairer/engineer. The cylinder pressuresand sealing problems in auto engines are small compared to high pressure pumps.

Thats why this forum is so good (the diversity of talents that contribute).

Yep all of those and more , I work as a maintenance engineer for Colgate Palmolive and we have a good variety of pumps here.
