Our carbureted AMR based kits are designed to work on 40/50hp upright style Type 1 engines using either a DCOE or HSR carburettor.
Featuring a wider dedicated drive belt to eliminate slip and overcome the excessive load on generator and alternator bearings found with single belt serpentine setups.
Our AMR500 based kits also feature square manifold ports to maximise flow capabilities and make the most of the available boost. Our high flow tee manifold will connect to both dual and singleport end castings and can also be used with CB EFI end castings.
Available with a range of inlet manifold styles you can use this kit with Weber DCOE’s, Dellorto DHLA’s, Mikuni HSR or with our own Joe Blow throttle body. We also offer this kit with AMR300 style flanges for smaller capacity engines. Just select the style of manifolds you need when ordering.

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 Capacity||Blower Type
Carburettor choice is largely a personal preference. The DCOE carburettors require deck-lid standoffs when installed on a bug. The HSR and S&S carburettors do not. The HSR / S&S 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
You will need to run decklid standoffs with the DCOE when installing on a bug
(we can supply custom standoffs – ask us)
Decklid standoffs are not required for the HSR and S&S Carburettors or JB Throttle Bodies
Standard tee manifold diameter will work with both dual and single-port end castings.
(other custom sizes are available – please ask!)
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.
