How good are you?

We ordered the inexpensive 44 weber knock offs for $400 to $500. CE here in Phoenix did the jetting and dyno tuning. My son and I built the engine from scratch starting with a new case, H beams, F8 cam... the heads are 44 intakes one step down from wedge ports with a semi hemi cut. We started with 7 pounds of boost and moved to 14 pounds. It runs amazing.

We'd have to pull the carb hats to see what the jetting is.

It's a ECU system that uses a gear attached to the crack pulley to determine when to fire the ignition instead of a distributor.

It's a pretty neat system but can be pretty expensive if you want all the bells and whistles.

I'm afraid I don't even know what "ms-1 crank fired ecu" is. We built lots of high performance engines, all but the last one naturally aspirated, and I would like to go fuel injection at some time but it's beyond my experience.

For the $400 you could have bought my used ms-1 crank fired ecu and had the option to go FI any time you wanted to buy the extra hardware........

It is often better to have a symmetrical tee where the boost pipe splits because otherwise the flow to one side may be favoured. As the cylinders open one at a time, this is not extremely critical but never the less something to think about.

Sorry for the delay in response. We used a fancy $200.... I think it was a fuel injection fuel pump placed under the tank. We also had a return line welded into the bottom of the tank. Our fuel pressure regulator looks like yours. It's supposed to increase fuel under boost. We got a $400 distributor from CB that can be programed to retard the timing under boost etc, all programmable with a laptop and a disk supplied by CB. This is a photo of the intake as we mocked it up before putting clamps on everything.

Well, that makes a difference then. Had webers in my head as when mine were turned inside, I couldn't get to the idle jets. Was thinking, "damn that shroud would have made,getting to those easier". Not as easy as efi though Very Happy

Space saver manifolds will turn the carbs around to idle jets inboard. Cb has them.

Nice score on an old school setup!

Depending on how much you want to invest and what your plans are for this vehicle, I'd highly recommend ditching the carbs and going with an EFI setup. Like one from thedubshop.net or CBs.

Who was the shop that originally built it? My son and I just recently finished his 2332 blow through turbo and it screams. Competition Engineering did the fabricating for the intake and built the exhaust for us. We built the engine. We run basically the same set up you have minus the 911 fan. My son's car is also a 63/64 rag painted like Herbie. We're about to install a trans built for his car, taller first gear, all the good stuff to hold up under this kind of power... 14 lbs of boost.

You really did score a great deal. Congratulations on that.

Update: It lives again!

Spent most of the day replacing fuel lines, cleaning float bowls and checking wiring. I found that the fuel pump had been hooked up wrong and was basically pushing air into the tank. Also found that the coil had been wired backwards as well. It would run without the turbo plumbed up but would stall once I hooked it all up. I pulled the turbo intake line off and pushed on the impeller which stuck at first then turned freely. Hooked it back up and runs great! -Guess it just needed a little nudge.

I drove it out of the garage and down the street the next day. Just putting, not wanting to do damage. Puts out a bit of white smoke which I am hoping will resolve after it is run a bit.

Next steps? I am probably going to take it to a shop to have the carbs synched and tuned. I have no experience with that. Also on this setup the carbs have the adjusting screws turned out which makes them nearly impossible to get to with the carbs in the car. I saw the CB Performance makes an intake manifold that rotates the carbs around is that worth the time/money to make that switch?

The fuel return from the regulator should really go back to the tank and not loop through a T piece.

If it has a high pressure FI pump, that can be considered as a 50 watt fuel heater and the fuel in the loop will get hot.
I have warmed up a gallon can of fuel using one of those pumps returning fuel to the can while checking out an old Bosch K-Jetronic FI system.

Just as well you blew out the fuel hose now not when it was running. And when the turbo is not running the fuel pressure should only be a few PSI at the carburettors. Check that.

Update: has gas going back to fuel regulator, turns out the fuel pump works much better when wired properly... At which point it blew out the 6+ year old field lines going from the regulator to the carbs. Looks like I am pulling carbs and replacing fuel line tomorrow.

I probably will. CB has a deal on now...

I could use the Dellorto book as well.
