Here is Colin Rowe's engine and installation.

The installation exectuted superbly by Colin!!

The proximity of the rampipes to the inner wing came as a bit of a surprise to me - I only just got the pictures weeks after instal and test and it leaves no room for any kind of filtration and I am very sure the lack of space is robbing the power (240BHP @7800 rpm) because of pressure-wave effects. It's astonishing how a metal surface can do this but it's true.

Some room for dyno-development here but the GC engine is good and has been run up to 8500 rpm which is always nice to hear from my preferred rolling road Northampton Motorsport. Report is that air that's actually getting in is burning well!

Injection system is Jenvey taper throttle bodies with Liferacing management and display. Gearbox is a 6 speed sequential by Maktrak (now gone)..
