Weber manifold for a B20

jrhendo

Hi all,

Has anybody any experience with the Mangoletsi twin weber manifold for a B20? Redline can't supply their usual manifold at the moment but I can source a Mangoletsi from the UK.

I've read that they're only suitable for LHD cars but the supplier assures me he's sold lots in the UK to RHD cars.

It's for a rally car with a 100mm deep air box, so my main concern is that will foul the steering shaft. The Redline manifold I have on another engine already puts it pretty close.

Regards

John

Pictures? I'd say it won't clear.

Also interested to see you rally car.

Here's a link to the manifold for sale ad, with photos. Not sure if it helps!

Re photos of the car, I'm currently in Buller for Targa High Country, so don't have anything with me, but if you go on Facebook and search for "John and Jeff do Sydney London 2014" or something like that, there'll be photos of the car and build etc at the beginning. I used fb as a blog for interested friends at the time.

In my days of youth and carburetor depravity, I had a pair of DCOE Webers firstly on a Lynx (Redline?) manifold, then later on the longer R-Sport manifolds.

I got around the steering column impact issue by using washers / spacers under the RH side engine mount, and using 6 cylinder TD Cortina engine mounts, which didn't instantly self-destruct upon application of throttle. The Cortina engine mounts were about 10mm shorter in height than standard Volvo fare, so the LH mount didn't get spacers.

I'll dig around and see if I have any pics of the setup from 30 years ago...

I'm running discovery V8 mounts and they do sit lower also.

We used xj6 jaguar engine mounts, get the longer manifolds there is a lot of horse power in them, the only clearance issue I remember was with the brake line on the rear trumpet

I have 2 old redline manifolds if u want one

That intake doesn't look that different to the redline one for length to me.

Rob, sounds very interesting. I've PMed you.

VQ, I think the length is less of an issue than the angle built in it to make the carbs clear the steering shaft.

May I ask, what's the benefit of putting Weber carbs in?

Vee_Que

For a race car, adjustablity in a class that doesn't allow programable fuel injection. It's also less complicated to set up overall once you grasp the concepts of tuning.

That is a links or redline in my profile picture I took the Volvo R sport manifolds off when I sold the car. The Volvo ones had about a 6" runner,made an amazing difference, so I kept them

That's shorter than the ones I have..

Does anyone have a Redline manifold for sale? Redline themselves are out if stock.

Try Webcon on www.webcon.co.uk - they advertise a full kit for Volvo B18/20, carbs, manifold, linkage, fittings and tuning manual. Not sure if they sell the manifold and other parts separately?
