chopping a std hs2 manifold

You also seemed to have missed out on the English spelling and grammer. This is not a reflection on yourself , but the current educational system.

you have a space between 'yourself' and the following comma

no need for that

Dislexic for the spelling issues and grammer but got a lot better I'm not lazy at spelling just words confuse me

You have no capital letter at the start and no period at the end.

Need for that .

in truth, im in no position to have a go at anyone for standards of english

Where would we be without spelling, grammer and punctuation?

Probably in a British secondary school or university.

im just wondering if its worth sticking with the set up i have (link pipe and std manifold0 or if i would get much gain by carefully chopping the inlet manifold part from the standard manifold and adding a freeflow type exhaust manifold. any opinions are grateful.

I have a chopped standard inlet for a single HS4 if you are interested. I'm based in the North East, so you must be near by. PM me if you are interested.

Look at Vortz to see what can be done with small carburettors, I'm not going into the technical ins and outs of what is needed here, but they as Speedwell believed border line carbs produced faster cars. Speedwell loved modified 1 1/8 as well. Vortz were always a size down for the same maximum output of others, and I'm prety sure there mentality of modify it first before we dismis it would apply to a single 1 1/4 on a 1000 as well.

Twin HS2s can cope with just about any engine spec, was at a hillclimb event few weeks back and speaking with entrant running a 1380 full spec Oselli motor with 286 scatter pattern cam. Last year he was running twin HS2s using Maniflow inlet manifold, can't remember the hp but his times were very good. Probably 100+ bhp at flywheel.

Main restriction on the standard single HS2 is likely to be the standard cast iron manifold, replace this with a decent manifold and it should work well for a 998. However as other posts have pointed out it is probably easier to go for a HS4 as decent manifolds for this are easier to obtain.
