Hey twospeed. Yep, that's me. The side-draft set up you sold me is great. Just needs a few misc parts, like new emulsion tubes and a few other size jets, and it's ready for set-up on a 1200. How did your exhaust finish? Got any pics to show us? Is your swap all complete and the car running?

You can see how much clearance is a problem for the 1200 with a side-draft carb. Not much room, but enough to make things go.

Not enough clearance on a gen 1 Civic.

Thanx Dan, I have never seen those before. Is there enough clearance to run them?

Kurt, I saw these on Pierce Manifold's website. I don't know how well they work, but you use them with the velocity stacks. If I ever get around to installing my sidedrafts, I'm going to try them. Dan

Thanx for the advice. I was told today my pump runs at 2-4 psi and not 1-2 as I originally thought. I have about 4 weeks until they arrive and I can't wait. I think I will have them set up professionally to avoid the hassle. Now I just have to decide on velocity stacks or air filters. The stacks look and sound better but I don't know id they are worth the risk.

Is that ted donnahue? I was wondering how the duel carbs I sold you worked out? Jared tolchard.

2 psi should be fine. Keeping the pressure under three is key as Weber's don't like to be force-fed. A pressure regulator should do the trick. Checking for low pressure is easy by simply running it at high RPM for a while to see if the bowl runs low.

I have the dual Dell setup and have been runnig a 5 psi pump and it's causing problems. I just bought a 2 psi regulator on the advice of Eurocarb. I haven't run it yet but Eurocarb says 2 psi is the correct pressure.

Webbers and Dellortos don't like a lot of fuel pressure so perhaps your carter might be enough. When used with a standard mechanical honda pump my 45 side draft cicic used a regulator set at 2 pounds per squinch

If I run dual carbs is it a must to change my fuel pump? I'm currently running a Carter pump but I think its only good up to 2 psi.

If it's the same as the one we get here it's going to love a bit of a tickle in the port department!!:D Drove one with a big port job in a Civic Rally car with a pair of 48-IDA's on a handmade manifold, a ford mexico...ish profile cam....extractors and a 2-1/4 inch straight through exhaust. Yeeehaaaaaa!

Thanx Hugh. I am runnning a header back to 2" exhaust so I should be okay there. I have heard the Canadian EL head is not too bad but I have also heard its a great head for porting.

By Hugh Johnson (Oneson1) (144.134.167.111) on Thursday, January 15, 2004 - 10:28 pm:

There is always a benefit from using velocity stacks as the airflow is smoothed before reaching the internal "chokes" inside the carbi,and it's somewhere to put the "sock" type aircleaners

Mileage depends almost entirely on tuning and the weight of your right foot, a lesson is to fill the (unattached to the vehicle) bowls of the carbies with fuel and rapidly open the throttle. Wow, what a fine water/petrol pistol and four barrelled at that. Every time you accelerate you squirt raw fuel just like that into the motor. So get it tuned properly and be gentle with your right foot.

Some more ign advance will help as will a pair of extractors, youve allowed your motor to breathe in well through the carbies and cam and it's capable of breathing out well with the cam, but the standard exhaust manifold is like a cork in the bottle! porting is only going to be of any really noticable good on a motor that is breathing well anyway.

This has been visited over and over but there are some remaining questions...

- I have heard that wen running a set of dual sidedrafts (40's) that the gas mileage is horrendous. Anyone know the miles per gallon? Just curious.

- I don't imagine anyone knows the jetting specs for the Weber DCOE 40 or the Dellorto 40 DHLB for the Canadian EL motor?

The head is stock other than a reground cam. Head work will have to wait for now but in the meantime I have heard that the distributor should be re curved? Anyone know what its worth to have done.

Lastly, is there any benefit to velocity stacks?

Thanx everyone,

Kurt
