Racerx128. Noone responded with 40 dcoe jetting for 2332. Bigger venturis and main jets than what i and madmike have should get you hauling. .

Running 34 venturis, 180 air, F11 emulsion 170 main but the plugs so a little lean. 200 needle and seat but going to go bigger after all the replies. Fuel inlet has already been opened up and screen removed. 55 idle jets.

 

[madmike]

yea up the needle &seat.
what's the pump jet?

Not sure. Carb works good and was originally setup by carcraft and the engine came out of a sandrail. I was just curious about a good starting point for jetting for the track. Thank you for all of your information.

Instead of drilling the four fuel entry holes at bottom of fuel well a smidgen bigger, I cut out the the area between the holes which leaves an oval slot entry on each side.

 

[r seidcheck]

Check pump jets size.... I've seen them opened way too big. (1.10, 1.15)..... 70 p/jets are a good start.... You might need 65 idle jets for off the line responce.. ..try 175 on main gas and small increments up as needed. Engine will pull strong without a hickup once enough fuel is supplied. I'm at around 700' elevation

 

[madmike]

I ended up with 55 Idles yesterday (make sure their is holes in the side of them cuz they look like IDA idles)
F 11 & F 7 E- tubes (yes u can run two different ones.)
180 Mains
175 & 155 airs
runs purdy good for 1915 and only 5 lbs of boost

 

[r seidcheck]

Madmike...try 175 airs 170 gas.

 

[r seidcheck]

And 10 psi .

 

[madmike]

more like 15 lbs stirring the pot:drivingskid::crazydriver:
I ordered a Turbosmart boost controller & a replacement diaphragm
for my other waste gate from Summit yesterday I was just on the 'spring ' in the gate
so no boost control just what it gave me.which wasn't enuff,,lol,
Ill let u know how this goes , Madmike

 

[madmike]

diaphragm was the wrong one,,, Think I'll be looking for a bad "Evolution Turbonetics waste gate to rebuild,LOL,,, I was getting 5lbs without the controller now closed it gets about 7 lbs, tuned it up and now the trans is out it kept popping out of 1st since i built itall back together,
going for a test drive today if it don't rain,,,

 

[madmike]

didn't rain so,
I took a friend for a spin, 5lbs, then 7 lbs.
'Life begins at 15 lbs" :drivingskid:
he's got a 'PermaGrin"
broke the tires loose at the top of every gear,granny shifting to brake in the syncros

 

[r seidcheck]

Was still a little rich. Fuel pressure 1.5 lb running.......now 175 airs, 165 gas. 1300 idle w/ this cam. Retuned after fabricating single chamber muffler to take out poppy sound to throaty tone.

 

[madmike]

Fun stuff, Their is awesome Fathers day cruise(200+cars) up here Saturday evening.
state & local cops block the main roads about 25 mile cruise total.
Lawn chairs,long water/garden hoses to the streets,, (burnout boxes every few hundred yards) my line lock is workin and I'm ready! Test drive,
gonna fill up the fuel tank and see how far it takes me(no gauge) 7 gal buggy tank.bringing some fuel too

40 DCOE Weber Jetting

So I have a 2332 turbo motor with a 40 dcoe side draft that came out of a sandrail and I stuck in my bug. I just started to race it and was wondering what a good starting point was for jets. Main, air, emulsion tubes. The car is plumbed with 3/8 hard line -6 fitting off the tank to a holley red pump and has a boost referenced holley regulator feeding the car. After doing some reading I know the carb is a little small to make any real power but it is a starting point in racing until I step up to a holley or efi.

Gentlemen,
I had a customer with a Turbo sand rail that had a Turbocharged 2110 with a 40DCOE. To make it really short he had this buggy at some big name shops. (I got to drive it) The buggy was good out of the hole but when the boost started to kick in the engine would lay over. If you feather the throttle, it would start to pull. If you stayed in it, Engine would start to ping (YIKES).
Anyway, the set up (I did not build this motor I got to inspect it)
2110
90.5X82, Engle 100, Stock rockers, on solid shafts, CB Performance 042 heads chamber 51cc; un touched 40X35.5, compression - 9.67:1 .060in Deck height. 40 DCOE draw through, holley blue pump, rising rate fuel pressure regulator 12-803 tapped for turbo. Idle fuel pressure 2.5psi. Plugs W8AC Ignition – 009 distributor with MSD 6. Timing limited to 22° BTDC
Jetting as received:
34mm venturies, Idle 55, Main gas 150, air correction 200, emulsion tube F11, needle and seat - 200
What I did:
Reset the compression, lowered deck height to .180”in. made it 7.3:1
Left the fuel system alone
40DCOE – Drilled the float well and main jet passages. Tapered the emulsion tubes, enlarged the main fuel openings on the emulsion tubes. Installed 250 needle and seat. Checked the float drop and readjusted (Wanted the float to drop as low as it could in the float bowl)
Jetting
34mm venturies, Idle 70, main gas 170, air correction 180, emulsion tube F2, needle and seat 250
I trashed the MSD 6, kept the 009 and used the Comp-U-Fire ignition WAYYY Better. Timing still 22° BTDC. Kept the W8AC plugs, Tried W7AC those would cause a stumble if just putting around the dunes.
14psi boost premium pump gas (No race fuel)
Results? - Well the customer sent me a video of him beating his Dad’s LSx powered buggy up competition hill. I have his picture with a HUGE grin on top of Competition Hill Glamis CA.
Oh the gentlemen staggering the emulsion tubes, the F11 and F7 is on the right track.

Randy

67 beetle.....Go for 24* max. Surprised you could force the blue fuel pump and 12 803 fpr down to 2 1/2 lbs. Someone must of changed them to the lighter red springs.

I agree with you on the timing. The owner and I moved the timing all around. Putting it at 22° the engine started a little easier...so I left it. (Not my ride)
Yeah that regulator had some work done. I was fully expecting to see mid 3 to mid 4psi on it.
The regulator I really like was from Claudes Buggy I don't see it any more.
Update on the 2110 Buggy. I did that in 2003, That buggy still runs as the owner now works at the same place I do. Some 4 or 5 years ago he compressed a couple of discs in his back so the Buggy is sitting, Waiting for his sons to take an interest.
I know that there are much better ways to fix that Buggy but at the time that is what we did.

Randy

 

[madmike]

Cruise route was about 40 miles.
I'm getting 14 mpg. with the play factor:drivingskid: so I'm happy

 

[madmike]

My cruising a/f could be better, so I plumb heat to the intake,in the form of hot oil,,, low&behold a/r's dropped to 12.5-13ish
I did install one 45 idle jet too,, but I'm swapping it for the 50 again today to see if it was the heated intake or what
or put another 45 in it and lean it out a bit more?

 

[racerx128]

Racerx128. Noone responded with 40 dcoe jetting for 2332. Bigger venturis and main jets than what i and madmike have should get you hauling. .

Thank you
