GRP... Engine... Thread...

I run the JP-3, good overall power and just about 11 minutes with the 6mm restrictor.
I really like this engine, the power delivery is very linear and smooth, unlike my JPX .28 which was an on/off switch
It also runs very cool.

i used the associated 2035 on mine when i was running that engine, it was really strong and good on fuel, i liked the 6.5mm restrictor better then the 6.0, another good choice on pipe is the 9853/053 pipes they work really well on this engine, i used the grp pipe that come in the promo kit and i couldnt get the performance i was looking for

thats what i was thinking ...i mean the dyn053 looks like a carbon copy of the 2053 grp ....so does the efra rating mean that the internals are different ....i mean the grp pipe looks nice and shinny ..but i mean the dyn053 hard coated looks infinitely more durable ....im gonna at least try it ...i mean how much less fuel mileage could i get .....????

Well, my GRP .21 dropped the bottom of the piston after about 3 gallons this weekend
It was a good motor for fuel mileage, but simply did not have enough bottom end poop for truggy after everything I tried. Tried stock 2053, JP1, JP3, and settled on 2035, and up in spur down in pinion.
So long GRP, it's been a fun venture, but I need more bottom end poop for my truggy.
Anyone that would like some GRP parts PM me. I have a 2053 pipe Case, Carb, Back plate, Crank, and Head that will go to eBay shortly. I'll gladly sell here first. Let me know what you are interested in I can send you pics we can talk price.

And yes I understand how to tune. Trust me it's not the tune.

This engine is great, not putting it down. No one should have to run a .28 for the bottom end poop I now am looking for in a truggy. In a buggy this thing would kick ass. Maybe I got a lemmon. Not sure... moving on...
