SU needels

[William Norway]

I have now done the conversion from Stromberg to Su carbs done now, i also changed the air filter to ot this ITG frefolow
https://etypeuk.com/services-by-e-type- ... -series-1/
and full exhaust form Classicfabs
https://classicfabs.co.uk/e-type-full-m ... st-systems

i now have the problem that the car runs lean, does anyone have this como and can advice me on that needels to go for ?

I run a similar setup (with gas flowed head) with UO needles to good effect.

One problem the larger bore exhausts can cause is a dip in torque around 2500 rpm, which is right in the middle of the operating rpm for the E Type. There are discussions on here, maybe a search for “torque” then search those results for “dip” will show you the comments and any suggested needles above what Steve has helpfully suggested.
