I've never seen a roll hoop with that extra extension on top before! For a tall driver I guess? Or if wearing a helmet maybe? Seems like an excellent idea to me. 

 

You used to see a few similar mods to the old RAC roll bar, back in the day. Not seen it done since the rule changes brought about the MSA roll bar, so i guess it was no longer compliant?

Been doing some quick cam timing tests, results in my development thread

Took my car to Northampton Motorsport last week for some attention to the cold starts and a map check.

 

Unless the car had been sitting in the garage on only the hottest of days, it would start fine but run a bit lumpy until — I can only guess — the coolant reached around 30°C or so. Easily resolved with a bit of gas or just starting to drive, but I wanted it checked over having previously replaced a duff CHT sensor.

 

Troy spent a morning running it up and down on the dyno, changing some of the ECU (OMEX) base settings and tweaking all the low RPM fuelling maps. As far as I know, it was as out the box by Westfield beforehand. Apparently, it had been configured to look for 9000 RPM, and by reducing it to a more realistic 7500 RPM, it gained a load of “resolution” in the map — fuelling is now more discrete and precise across the RPM range. The idle control values were also set poorly in the ECU and needed doubling to their maximum.

 

Anyway, it now starts and idles great, but I’ll need to wait for it to be truly “cold” to see how it behaves.

The dyno work did manage to kill the exhaust bobbin — too hot in low or no airflow — but it’s easy enough to replace.

 

The whole team there were really helpful and deserve the good reputation they get on the forum.

Gotta get mine there sometime, it's not had a full dyno session since Troy did it in 2019
