hot side almost done little more tweaking and weld

Oil lines hooked up? How did you plumb your return line?

I was curious on how you would plumb the oil lines myself.

How will you handle pressurizing the carbs? I'm assuming a blow through the carbs application? Or will you build a pressurized box that the carbs fit inside?

Are you planning to use that "wrinkle wall" tubing on the hot side, or is that for mock up?

Thank you & good luck.

a may have just had an "incident" after that video cant wait to see her done mate

The oil lines are not hooked up yet I only ran it for about 10 seconds but the ol lines are my next step I think in going to replace the plug on the side of oil pan with a fitting to run feed line and for return I'm going to most likely drill an tap the clutch cover. Still open to suggestions on this. And as far as pressuring the carbs I plan on using a pitot tube in the charge pipe. Most people seem to have great success this way. I think I have an idea to put a spin on the concept by using an oversized pitot tube and running it thru a boost controller to be able to fine tune bowl pressure. Between that and adjustable boost referanced fuel pressure regulated it should take some of the monotony out of tuning. Still just a concept tho.

Forgot to answer the exhaust question. That pipe setup will be temporary. When I get everything working properly I will have that duplicated with mandrel bend one piece with a flange at the flex pipe for easier removal.

Can you explain this further? You lost me at "pitot tube". LOL!

Thank you

Here is a description of Pitot tubes.

 pitot tube is a smaller tube that is placed inside the charge pipe with the opening facing against the direction of airflow this i will be then plumber to the float bowl vents so the pressure in the carbs matches that of the intake pressure. also will be my waste gate reference. here is an example if a pitot tube in an intake manifold i found on google

Thanks. I was aware of what a pitot tube was, I just didn't understand it's function in this system.

jnimbostratus

size of pitot tube seems to be the most difficult part of getting the carbs to work properly and from the research i have done most people end up doing alot of trial an error to get it just right then i read on another furom one huy tapped his pitot tube to except holley carb jets to adjust pitot tube. i plan to do somthing very similar to this by using a slightly oversized pitot tube and using an inline Manuel boost controller between pitot and carb

MLdesigns

Wouldnt you then have to adjust ur pitot pressure based on the turbo pressure at different rpm or woukd the boost pressure be a constant that u cpuld match the pitot to? Because if it was changing could you use an adjustable boost controller thats auto adjusting so u could dial it in for +or-tge incoming boost to balance the system pressure based on incoming charge all the time. Never built a tubby just a thought i had. Disregard and nonscence if u want mate....

jnimbostratus

the pressure the pitot tube sees is a constant to the charge pipe so it will always be a constant so no need for anything auto adjusting thats why i will be referancing everything boost related off of it. the idea of the manuel boost controller for carb pressure is because i dont know of an exact science for boost ratio to the float bowl. if that mkes sence to your question.
