Blower choice should be determined by your engine capacity and the amount of boost you want to run. You can use the following table to help you select your blower.

Engine CapacityBlower Type

Carburettor choice is largely a personal preference. The DCOE carburettors require deck-lid standoffs when installed on a bug. The HSR carburettors do not. The HSR size needs to be matched to the engine capacity, whereas the DCOE can be tuned to suit a range of engine capacities, however if you have different requirements we can mix and match the sizes to suit your application. Please feel free to discuss this with us when ordering.

Carburettors are supplied with a baseline tune that will get your engine running. From there you can then dial in the tune for your engine.

Note: Carburettors and blowers are sold separately


We strongly recommend that you run water-methanol injection (WMI) with this kit to manage intake temps.
Our ignition system includes WMI control.
We recommend installation in conjunction with a performance exhaust system for best results
Installation of an external oil cooler is recommended.

Tuning and setup

Where supplied with kits, carburettors are fitted with a baseline tune, this is sufficient to get your engine running but will not be the correct tune for YOUR engine. You WILL need to undertake further tuning to dial the kit in for your engine.
Baseline jetting and carburettor setup is included in the documentation provided with the kit.
The documentation also includes full step-by-step instructions on how you can undertake the tuning yourself using a readily available wide-band AFR gauge.
We also provide full support via our online help-desk and knowledge-base.
