Does anyone have any experience or be able to hazard a guess at what difference (if any) dual carbs would make to a stock 1300dp motor? I'm guessing since I couldn't find anyone who's actually done it, not enough to make it worth the cost.

I was only thinking about it because I was considering repalcing my (broken) muffler with a set of extractors and an aftermarket muffler and was thinking that these wouldn't have the manifold heat pipes.

yeah, many/most extractors have the heat riser pipes still. My Thunderbird pipes do

Yes many of the extractor exhaust systems have the heat riser pipe attachments...
but a 1300 would still be OK with twin carbs like kadrons...
I know that there are single port 1500 & 1600 twin carb engines out there.....

40mm Kads maybe a little big for a 1300,OR SO IVE HEARD :blah

yeah, if your going to spend money best thing to do is get a single weber and new manifold to suit. this will be cheaper and these come without risers and would suit your 1300DP a lot better. you can block the risers on the extractors anyway.

btw' is your car an automatic

No, it's manual.

When you say 40mm Kadrons, what does the 40mm refer to?

mmmmm, over-carbing. You wouldn't have to worry about a choke, ha ha :P

I have a mate who had twin 45mm webers (with 45mm chokes) on a 5k (1500cc) toyota 4 banger in an early corolla. When it was cold all he had to do was turn the key. for the first 10 minutes all you could smeel was the raw fuel pouring out the exhaust.

However, if even he breathed on the accelerator, the engine would flood and die.

but I tell you what, it sounded awesome and went really hard!

Kads may be okay but you'd have to reduce the jets a shi load. The sinle webber may be the best option.

Y'know I'm tempted to give it a shot anyway just to see what happens

go'on, you know you want to.....:thumb

Pobjoy once built up a 25hp motor for an oval historic racer with a counterweighted crank and monster induction, said it sounded and went awesome, said a whole bunch of other stuff too, but that's just Stan, he can really talk......mmmm.....ok I'll be quiet now.:o

Of course I want to It's parting company with hard earned notes that's holding me back.

Anyone want to donate a pair of carbs for me to do some testing with?

geez craig, if Stan starts a frequent flyer program you'll be off on a round the world ticket straght away.

BTW, how does it go? what sort of horses do you reckon it's good for and what did stan actually do to it? He was talking alot at the time he told me, but it was a while ago.

Hi

I reckon a single 40mm webber would be a better choice than twins, twins will get out of sync and its a bitch to change plugs with twin carbs, Kadrons make a lot of noise for little affect.

Steve

:jesus.................I guess it does take about 11 seconds more to change each plug

It's academic anyway. I figured the only way to find out how well twin Kadrons would work on a 1300 is to put some on there. I've already bought the carbs and manifolds of primate, and just need to get the rest of the bits before I bolt it up and see whether I've wasted my time and money or not.

Hi Craig

You must have British Leyland hands then.

Steve

Have you thought about going 1640cc??? change of Piston and barrels and machining of the heads.......................not too sure how mechanical you are??


Certainly not Japanese hands:repuke

I have thought about it. I've even got a spare 1600 motor sitting in bits out in the shed. Trouble is at the time I bought it my income was limited so I decided not to spend money on it yet.
