Yes it is, as in Vizard's book, but carb was special for a Lotus.

Jukka Harkola (MM site) did it on a Mini with turbo, had lots of grief to get it right.

Suck-thru is commonest for supercharging, but not great for turbo where the turbine runs a zillion rpm.. :wink:

Wasn't Jukka- I think his bro. Look on that V8 site, there's a link to Jukka's turbo Min stuff.

found this on google groups (USENET) while reading up on dellortos:

Quote:
A friend has been working on a turbo conversion for his mini, but
having already had a straighforward Metro Turbo conversion, he decided
on something a little different:

Dellorto 45 DHLA, (as used on the Lotus Turbo Esprit)
Intercooler
Dump valve
Front mounted (Mk2 Metro) radiator
Straight cut box and drop gears.
Maniflow exhaust
Safety devices roll cage
7x13" Superlights
Polycarbonate windows
Fibeglass boot and bonnet
Twin tanks
Metro four pot calipers and vented disks
as well as the usual HiLo's, adjustable shocks etc

Anyway, he finaly got the engine running after a couple of weeks of
nightmares. The enigne ran first time but a load tapping noise was
comming from the area of the timing case. After removing the timing
cover nothing was found, but the noise was still there, and not
sounding healthy. He decided to remove the engine and strip it,
mainly for his own peace of mind, but found nothing, and the noise was
still present after reassembly. Eventualy, it was found to be nothing
more serious than the crank pulley was touching a high spot on the
timing cover!

The next plan is to sort out a distributorless ignition, as the
raditor doesn't leave a lot of space! He's aquired a distributorless
coil from a F*rd and we have come up with a way to modify the existing
distributor to just provide timming for the sparks, but no spark
distribution.(and therefore no distributor cap/ht leads)

Anyway, he's got a digital camera, and he's not afraid to use it, so
he's put hnudreds of pic's on his web site. If you are interested
take a look at
http://www.users.globalnet.co.uk/~mlarj ... stuff.html


picture link still works, love the air box!

The biggest problem you have is that you have to pressurise the float chambers so the fuel flows in the right direction on boost, and seal a whole heap of fiddly little bits to make sure that the boost pressure does not force stuff in the wrong direction. Plus you have to fiddle a lot to get your mixtures right because it is not a common thing to do. The big advantage with the blow through is you can use an intercooler before the carby.

Ever wonder why turbocharching never really took off untill EFI was sorted?

Eurocarb can help you- they stock all the bits for the Esprit turbo's special 45 Dellorto carb.

He did a Dell'orto turbo, but was running a DHLA 45M carb already modified for a turbo. It is my understanding though that you can modify a normal Dell'orto to use as a blow through.

As for using it on a suck through, it seems to me a bit pointless running a twin choke carb on a suck through turbo, but maybe it's just me!

There was a two barrel downdraught Weber specially made for blow-through turbos.

One sold on e-Bay a few months ago - 34DMTT I think?

You can get a manifold to fit this carb onto a Mini, as the popular 28/36DCD and 32/36DGV carbs use the same bolt spacing. 8)
