I can aquire some DHLA 40 Lotus Esprit Turbo carburettors as a direct replacment for mine; and i can also get a m45 Eaton charger from a friend who races Cooper S's for dirt cheap..
Is this just a matter of room ? As i'd have to find some replacment pulley also.
But in terms of managment, would i have to run a Mapped iginition ? Would it be safe to run on 10psi with a cometic head gasket; bearing in mind i have a rather strong bottom end :)
Being honest, i'd be more tempted use a standard 1600 mpi inlet. And run Efi.
You'd need a very good carb tuner, and yeah mapped ignition.
nick... I like the way you think, but I think it should be one or the other. Saying that tho R5 Turbo's are carb'ed, and they see good results. If your going to need management then i think you might as well use efi. Also your fuel bill would be huge lol
R5 etc was carb'd because it was cheaper etc for them to do back when they were designing the car in the 80s.
Id go efi, unless you really wanted to stay carbs for some reason.
r5 are carb's, but a lot of the high powered one's are converted to mpi
But i'm assuming the Dellorto DHLA's are a bit higher-tech and originally alot more expensive than the Webber twin barrel carb that's on the R5 ?
If lotus ran them on their esprits, i'd imagine they're fairly good - they can cope with 30psi apparently.
The parts are available to me for cheap, The sound of Carbs and a Supercharger would be awesome.
The carbs intake would be completely "boxed" in tho, so you wouldn't get the sound of normal NA carbs.
Youd need some form of mount for the charger, and obvious bits like a custom belt. Might need mod bits of the car too depending where you mount the charger.
well, i'm getting hold of a Eaton M45 to have a look regarding size/placment.
If my mate can source a bottom pully that can run a dual belt i might just give it a go.
If it's ****e, i can just sell the bits on and make a bit of money to recouperate RR/Cometic Headgasket costs.

They seem to go for quite an amount.
if anything, use DCOE 152 carbs as there suitable for turbo applications in OE spec.
Altho id go MPi all the way if it were me
