well yeah, im aiming for 80 so if i fall short ill still be up there

Ben is aiming for 90 out of his which is why i said it

[liirge]

Its a standard 1275 casting :/
10:75:1 i think

Mg metro aint bad yeah its the same as an SW5 ish at the end of the day cause thats what Swifty based it on.

Yeah they use weber on one side only. Single choke only.

I just think looking at Ben Pophams Build, Your build, Liirges and Mine we are all going fairly similar within reason and the most we expect is about 90
I suppose if they fully ligtened EVERYTHING they might get that increase through sheer stress and friction reduction.

Very much doubt I will get 90, 80 or maybe even 85 would be a blessing, and is a target but it still wouldn't surprise me if it falls short of that.

To be honest, im hoping of 55 at the wheels (maybe 70 at the fly), anything more is a bunus

To get anywhere near 90 i think your looking at weber (as Vizard does in the yellow bible)

[liirge]

pair of twin SU HS4's is more than capable of the air flow requirements.

[twrminisport]

HS2's in twin are effective until about 85bhp.
Modified as per Vizard they will do the buisness really

I'm afraid I'm somewhat sceptical about that, especially as these smaller motors have to be revved so high.

[PhilipGCaldwell]

do you think a Hif44 will give as good power output as twin HS2s?
A friend is selling a good Hif44 with an ITG filter and Im pretty interested, saves trying to balance the twins and is less hassle,hmmmm

[twrminisport]

to be honest it should do on a decent manifold

You can make HS2's perform like HS4's though remember with the right modification
HS2's will always be more efficent but the HIF44 is so big you get the figure still.

[PhilipGCaldwell]

hmmm, I will have a think, the Hs2s I have still need a wee bit of rebuilding, the throttle spindle needs rebushing

Got the dyno booked yet?

Shall we start a book as to the exact bhp / torque?

prob a few weeks off the dyno yet, want to get it run in then tak it for RR

[twrminisport]

Ahh let us know

Make sure you post up a FULL SPEC which is current with it though

Bought this Camber Kit this morning, fully adjustable

http://www.minispare...amp;prod_id=161

Waiting on news from the machine shop as to whether they got the cam bearings in ok

[PhilipGCaldwell]

rang machineshop today and they still havent fitted the cam bearings so project still on hold
I have the gearbox off my original engine all ready to drop the block onto, also fiited my neg camber kit

I have decided to stick with the twin HS2, just need the throttle spindles rebushing, will get them off minispares, I was briefly looking at putting on a weber DCOE40 on a homemade intake manifold (I was guna fabricate a manifold at work as we have lots of tubing and a plasma cutter to make the flanges) this would be done to save me cutting the bulkhead/using the rubbish swan neck manifold
