Hi people, im just finishing the engine on the GT, the spec is as follows:

1275 A+ bottom end, rebuilt first oversize with MG Metro pistons,
Stage 1 late MG Metro head, (33mm inlets, ported to vizard spec)
HIF 44 on a sportex (same as howley) manifold, (ported to vizard spec)
K & N cone filter,
Kent MD286 cam,
Metro cast LCB manifold,
A+ rocker gear (i believe this is 1.2-1.25 ratio?)

Soo.. my question is thus.. what needle should i be aiming for? Am i right in thinking the 44 has .010 jets? do these remain with a needle change?

Anyone want to put an estimate as to flywheel power? im hoping for 80ish, is this realistic?

stu.

well its always hard to get a starting point, a friend of mine with a slightly higher spec engine had a BDR needle but i believe it was modified!! that should help you out tho! above all please get it setup on rolling road!!

hey not a bad one eh a proper lcb would probably be an adbvantage to you tho, the cast iron metro one isnt great

[miniman86]

leonard what software is that and whered u get it from?

[Leonard]

winsu says with lcb itll go up to 84bhp

miniman86, winsu you only get 5 free goes, after this pay about a tenner and its yours forever

my win su trial only shows 82bhp (at flywheel) for the following

1330cc engine
HIF44 carb
Large K&N
Minispares alloy inlet
LCB and twin box system
mg metro head
kent 286 cam
standard rockers
points and condensor
3.44 diff

So that figure seems a little high

I get 76bhp for the spec posted in the 1st post. WinSu v2.6

sorry to go off topic but i am just putting an mg metro in my mini and i wondering how you connected/ or what exhasut you connected up to the metro manifold?

[cool_stu]

I kept the standard metro downpipes and got my local exhaust place to alter and fabricate me a single box system in stainless to suit..

I was gonna use the metro setup, and fabricate it myself, but mates rates came into play and made me an offer i couldnt refuse!

jordie,

86 bhp
recommended needle bdr
other needles to try, bdk, bdp

nice spec by the way. with that cam, if you ever put a well worked head on there, it'll release loads of extra ponies

[Jordie]

cheers. Head is something i will be upgrading in the summer. more ponies = more pennies!

[Leonard]

ponies means prizes. apparently a ported head with 37/29 valves will gives you 96bhp!
