6338 - Full Mod FAT BOY 46cc / 47cc Reed Case Engine - Goped

Fully ported GP460 engine complete with carb and clutch.

All G320/340 reed engines now come with a V2 reed case as well as reed valve. The V2 case has been redesigned to produce more power and eliminate the need for a mesh mod without effecting cooling or air flow.

G320RC vs G340RC the G320 revs higher due to the smaller stroke crank and the G340 being a stroked engine has more torque.

We're proud to announce the release of our full mod G340RC reed case engine. Big thanks to Dave@Turtle Racing for all of your help making these cases. Designed similar to our current reed cases with a replaceable fan cover. We've stuffed the case and taken out as much case volume as possible to help with performance. We've also changed the geometry in the transfer bowls to flow more fuel. We've used a similar intake tract that has been proven on our dyno and flow bench to produce more power. This engine is rated at 9.4hp with a max rpm of over 20,000 on our dyno. Gearing, car/truck weight, exhaust etc will be a factor in rpm's. This engine is fully modified just like our 29.5cc and 30.5cc reed engines. We modify the transfer ports, piston, intake port, exhaust port, cut and reshape combustion chamber and change duration's to our specs as well as cut a boost port and window the piston to match. This engine has the same size exhaust port as the current 22.5cc - 30.5cc engines so a new pipe is not needed. 

G320/340RC has the following improvements over the G290RC
Larger crankcase bearings
Larger lower connecting rod bearing
Larger needle bearing
Enclosed transfer ports with removal plate

Parts that are different and not compatible with our current engines are:
Cylinder

We're proud to announce the release of our full mod G320RC reed case engine. You have the option to order with or without carb and clutch. Big thanks to Dave@Turtle Racing for all of your help making these cases.

We've also changed the geometry in the transfer bowls to flow more fuel. We've used a similar intake tract that has been proven on our dyno and flow bench to produce more power. This engine is rated at 9.1hp with a max rpm of over 20,000 on our dyno. Gearing, car/truck weight, exhaust etc will be a factor in rpm's. This engine is fully modified just like our 29.5cc and 30.5cc reed engines. We modify the transfer ports, piston, intake port, exhaust port, cut and reshape combustion chamber and change duration's to our specs as well as cut a boost port and window the piston to match. This engine comes complete with clutch(Air filter and exhaust not included). You have the option to order this engine with or without a carb.  This engine has the same size exhaust port as the current 22.5cc - 30.5cc engines so a new  pipe is not needed. 

Fits: HPI Baja 5B 5T 5SC 5R, Kraken Vekta , Losi 5ive-T, Recat Dune Runner/MT

Fits Losi 5ive-T 1.0 and Rovan/30 Defree North trucks that are a clone of the 1.0. If you're unsure reach out to us before ordering and send pictures or a link to the truck you have. 

DOES NOT FIT: 5ive-T 2.0, 5ive-B, DBXL, MTXL, HPI, Redcat or MCD.

These engines are now available with the option to add an OBR pipe to make it a complete package.

Complete fully modified/ported 46/47cc engine for Losi 5ive-T 1.0 use. Does not fit Losi 5ive-T 2.0 or any other 1/5 scale car. Engine comes complete with clutch, HDA-223 carb and v-stack. You have the option of adding a mounting kit, exhaust and pinion to make it a complete package like our full mod that will have everything needed to install. For those that already have our full mod 46/47cc the engine can be purchased by itself. Pipe, gearing, mounting etc is exactly the same for the full mod and reed version. Mounting kit and pipes are required to mount and run this engine. 34cc and smaller exhaust pipes will not fit as this engine has a larger exhaust port.  Intake tract, reed valve and transfer bowls were in-house flow tested and dyno tested to produce as much power as possible. You can expect to see a lot more torque and mid range power then a piston port 46/47cc without a loss in rpm's. We've used high quality carbon fiber reed petals for more power and longer life then fiberglass petals.

Porting/machining:

intake port filled and 2 boost ports added

piston lightened/reshaped w/dual windows to match boost ports

all ports resurfaced

transfer port bridge knife edged

exhaust duration advanced

exhaust port widened and flowed

46/47cc reed engine for the Primal MT. You have the option to add a mounting kit and exhaust header to make it a complete package that is ready to bolt up and run. Mounting kit is required to install the 46/47cc reed engine. Our exhaust header requires use of the stock pipe. We hope to have a complete tuned pipe in the near future. 

Engine comes complete with clutch, HDA-223 carb and v-stack. Intake tract, reed valve and transfer bowls were in-house flow tested and dyno tested to produce as much power as possible. You can expect to see a massive increase in power over the stock 49cc along with a longer life. We've used high quality carbon fiber reed petals for more power and longer life then fiberglass petals.
