Hi guys right i'm gonna kick off with my carb issues! I am using a hif44 on my renault 5 turbo and i'm having issues with on boost fueling, cruise is fine etc but around 4k when coming on boost it starts to run lean as if its not pulling the fuel hard enough. I have made an inlet plenum and there is no restrictor in it so will that be an issue?? Tried filing needles etc but still runs lean, messed around with float level and needle vaves, tried different viscosity oils in dashpot as well! I have blanked off the pipe which is next to the fuel inlet on the carb and i have also blanked off the pipe which is at an angle, think they both go into float chamber and inside of carb?

The restictor is essential in terms of making the carb work properly under boost, there is a really good post about it some where, I'll try and find it. Isambard Kingdom Brunel said:

Then realise it's a bit cold and there's beer in the fridge and go back in. Then basically make excuses 'til some time in mid June, before finally spending every free hour in the garage from then 'til midnight before the Mini showdown. I guess having a n R5 means you don't follow this ritual. Fastest 998 mini in the world? 13.05 1/4 mile 106mph

Right i can now speak with authority!! If you do not use the restrictor in the plenum then it will completely lean out your on boost fueling! I have gone through numerous needles and tried lots of float levels in fact i think i have tried nearly everything!

In Graham Bells forced induction bible he speaks of each 90degree bend in charge piping results in a 1psi. drop in pressure.

That is a very good idea, mainly alowing you to run less boost at the compressor, and likely to result in running in a higher efficiency zone.

, funny thing is, since that time I found like 2-3 hif44's that are turbo-ready. One of them is in great condition, but lacks needle.
