Helix High Flow 380cc Injectors Are Back!

[Ralph@Helix]

After about a year without these we are happy to announce that we have brought back our High Flow 380cc Injectors for the 2002-2006 R53 Mini Cooper S and 2004-2008 Cooper S Convertibles.


The Helix High Flow 380cc injectors are now white and use a 1-piece electrical adapter to make it a direct fit. These injectors are still manufactured by Bosch and flow 380cc/min., and still have the 15% dual cone spray pattern.


Why a twin cone pattern? because the engineers at MINI designed the OEM injectors to flow directly at the intake valves, not at the central bridge. Here's a shot of the intake ports of a MINI head. Sorry for the photography and file size...

The above picture shows a stock MINI intake port in detail. A central bridge is clearly visible. This is where the main inlet port becomes split to direct air (and fuel) towards the intake valves. The correct injector type for this inlet configuration is one where the injector nozzle sprays a precisely split amount of fuel directly into each port and onto the back of each intake valve. An injector that sprays a single narrow fuel cone will wet the metal walls and causes fuel to dribble into the combustion chamber. Tuning/holding precise air/fuel ratios is thusly complicated.

Here's a rather out-of-focus clip of a single stream, aftermarket injector's spray pattern (no worries, I made the clip short):

Now here's a clip of the new helix 15% split stream injectors:
