I'm helping my mate recomission his Cox Gtm which is fitted with a 1330 a series engine with worked head and we think a 286 cam it came with a 40 dcoe fitted which is in a very poor state so we have decieded to fit a Hif 44 su to get it running and make it easier to set up at home before getting it on the rolling road. What needle/ spring would you advise as a starting point to get it running at a safe level?

 

Andy.

I had a 1293 with a 286 and worked head which ran perfectly with a BDL. I've also had a 1330 with and evo1 cam and very well flowed head which went well with a BDP. Someone with more knowledge than me will be able to give you a better steer but either of those may be a reasonable starting point.

As Mrpeanut says you may well be ok with BDL or BDP  they are both a usable needle for a tuned 1275cc plus...BDL is the standard MG metro BDP is generally stage one. BBC (nowt to do with telly or Blackburn brake and clutch haha) is a good one for a 286/296 cammed engine.

All three are very similar at the bottom end, BBC being leaner at the bottom and then much richer...its gunna be a guess anyway as its pretty much an unknown motor and I guess won't be run much or revved too high before the dyno.

By Bottom end I mean the thick end of the needle, bottom end of revs / throttle.

If you can get it started/running and revving a bit without drowning the plugs and ticking over reasonably (even if its high) then its dyno time

Hope this helps

The jetting in the weber Will give away what needle would be good.

hi yall

its been a while.

well i have caddy on the road.

goes like a rocket.

i am running a bdd needle in my hif44 on a 1330cc with 276 kent cam but its a bit juicy on fuel.

roller rockers 1.5 LDX, med pistons and pushrods, lightened and balanced flywheel with a turbo clutch plate.

the standard needle was a bfm, had it static tuned and a bdd was fitted which allowed her to run better.

idle is a little lumpy due to the cam and im running a k&n air filter.

too improve the fuel range i had a 10.5 gallon tank custom made and that's in the boot in-place of the standard tank.

is there another needle or needles i can try to reduce fuel consumption but still have the same acceleration.

any help would be good.

regards

Hi there....I would like to avoid new topic so I will post my question here...

 

I have newly rebuilt Hif44 (all new parts) and I will use it with 1290 engine, fitted with Evo001 cam, K&N filter, 1.27 standard rockers assembly, LCB RC40, lighterflyweel, 35.7 intake valves, slightly bored head...

 

My question is what would be good hif 44 spring and needle as a starting position for this engine. I am hoping for 95HP.

 

Thanks in advance!

Think you're being a bit ambitious looking for 95bhp with that setup.

I am sure you are right but what to add to gain at least 90?

A better head and bigger cam. But if it's a roadcar just keep your spec and enjoy the torque.

If you have not had it on a rolling road you are  guessing,  as is everyone else

 

...get it set up correctly you will have the best of both

 

After a RR session its at optimum efficiency... don't boot it and you get the optimum fuel use

 

A rolling road tune is a lot cheaper than fuel
