Quick T40 choke question

[mad-driver]

Can anyone tell me what chokes i should be running in my 40s? The engine is as follows:

14nv block
1300 head
285 cam
40DHLA carbs
ashley 4 branch and magnex system

Someone has told me i need 34mm chokes but that just seems stupid, i mean i'm sure it was benji who told me on an engine like mine you should run a max of 32mm IF you have a big valve head. Does that sound about right?

By the way it has 28mm in atm

ring up someone like
fastroadcars.co.uk
or eurocarb they will be able to tell you

I'd say 30mm chokes would do for that spec

ditto on the 30 front

[mad-driver]

thought something like that sounded about right, 34 way too large

cheers chaps :thumb:

lol jims only just about uses 34mm chokes!!!

[mad-driver]

exactly lol, which is why i was a tad optimistic about the idea

i got some spare 30's (DHLA) if your intersted. Might even trade them for your 34's.

[Dan]

yep i agree with 30's also, i to run 34's in mine

[mad-driver]

lol, i dont have 34s in mine, someone told me i should have but i swiftly told them differently! I believe mine are 28mm so i guess they should be ok unless i went for bigger valves?

[Snowface]

you probably won't be reaching your maximum power but you should gain a few pounds of torque at mid range.

[mad-driver]

so maybe 30mm chokes would be better for what i have atm?
