Another question from me...

I currently have a 38DGMS carb to bolt onto my pinto.

Potentially I can get a pair of 40DHLAs. According to the jetting calculator on Dave Andrews website 40's will give me a maximum of 6000-6250rpm peak power with 36-37mm chokes. (more than enough with a std pinto bottom end?!)

Question is, is it worth upgrading to a pair of 40DHLAs over my 38DGMS? If so what advantages could I expect?

Cheers,
David

Hmmm the noise of 40's

Not sure about Twin 40DHLAs but I think Twin 40 DCOE's only usually have a 32mm choke and from what I remember you either can't change them because it lessens the venturi effect or it was certainly expencive.

Much more kudos (or is that an aftershave?).

And girls will swoon at the sight of your exposed trumpets!

Get bike carbs.

- Better fuel economy
- Better performance
- Better sound
- Easier to setup
- Stay on tune better

Can you tell I really like my R1 carbs?


Bike Carbs 1

Do the bike carbs sound nice Andy??

Cant wait to get mine on.
Go on David - fit bke carbs and megajolt (after SVA???).

Chokes are available upto 36mm for 40DCOEs and 37mm for 40DHLAs. Aux venturis are the expensive bit from what i can gather.

I must say I like the idea of bike carbs. But I would like to hear some rolling road results comparing a bike carbed set up to a twin carb setup if i was going to go that way...

Darren, megajolt is beyond me at the moment. I like to keep it simple, give me more chance of fixing it at the side of the road if it conks out

Any more input welcome

I bought twin DHLA 40's that have been set up for a 2.0l pinto and I think they have 34mm chokes and 36mm is a maximum. Don't people say a 2.0l is best with 45's anyway.

Having read the recent Bogg Bros thread I could well be going the R1 carb route now. I've been watching a few go on EBAY and they seem to go around the £100 mark so cheaper to buy than Webbortos too.

By the time I've bought a manifold, linkages and ram pipes I'll probably have spent more than the £300 quoted on here for a package from Boggs.

If I hadn't got them in the garage I'd definitely go the R1 carb route as they seem to do more for similar money.

Have a quick read of this its a zetec with gsxr750 tbs though, but it might help

i'm already on 40's but i think bike bits are the way to go

Andy do they really sound better ? i've never heard them run, but lots of people are saying good things

Finally got around to uploading the video I made just after fitting the bike carbs (ignore the bodged throttle cable).

Warning: it's 90BM so if you haven't got broadbeans you should have.

I'll stick with my 40's, if i did'nt already have them i'd probley go with the bike bits.

Ps nice vid, and good upgrade
