Twin carb manifold

Post by **Carl** » 24 Mar 2006 06:06 pm

Just looking at some manifolds for the twin carbies I'm getting obsessed with.

There's 2 options - a short one and a long one, both of which can be seens here: http://www.kgtrimning.com/insug.htm

Whats the pros and cons of each one? I'll probably be using 40s if that makes a difference.

i think it depends what carbs/trumpets/filters you use ,theres not too much room......see below ;

your be better off with the short ones they do, because that will give you more room in the engine bay for the air filters.

In performance wise, long ones give bit slower response and more torque, with short ones faster reaction and more top end, but that may be as much as impossible to measure with arse, but this is what it is in theory and what rally ppl has been telling.

Sounds like the short one wins all round then. Cheers guys. Just need to find the money now

Giving the roadies a miss?-or are they a r sport dealer accessory

Well most events round my way run on navigational permits so technically I could get away with it if the organisors are ok with it. Plus club 12 cars are fine. It just means I wont be able to do proper road rallies (unless I use the Manta), but I'm fine with that. Just wanna go out and have a laugh

I spose you could argue the dealer accessory with the carbs, but the extra engine capacity might cause an issue

For goodness sake make sure you fit air filters. Running open trumpet doesn't gain you measurable power, but will gum up your rings pretty damn quickly. The only application where it's 'safe' is high-level competition usage, where the engines are rebuilt after very limited usage.

and fit good ones !! not those crappy foam ones that set on fire easy

the alpha air boxes are ideal[maybe fiat ones too but i'm not 100%] if you find one and get the carbs too !!!!

£40 my brother got his for and got £140[ish?] on ebay for them - not bad for 30 mins work. buckets of sh1t and roses spring to mind.........

Fitting 4x small cone type K&N could be something special

what filters do you use foggy ?

The crappy foam ones that set on fire easily

Except they don't. Another urban myth with sidedraft carbs, like the Solexs being shite. Mine have been saturated with fuel, and the enigne fires forwards all the time (damn you tuning, you win this time), but a almost year later they're still there...touch wood

cheers

I thought about yours as soon as he said that lol

Post by **Bilbo** » 29 Mar 2006 05:29 pm

hehee

we couldnt use them - they would go up in smoke i think .
as for carbs ,if they are set up ok i dont think it matters what make they are ,they all sound and go great

I'd definately be using a proper airbox, none of this foam nonsense as it wouldn't be good drving through water/mud!!

Might have got my dirty mits on some Dellorto DLHA 40s....
