R/C Tech Forums - GRP... Engine... Thread...

I got a brand new GRP tuned that has been hiding in a friends motor box. The only prob is it needs HSN orings. Found a guy on flebay with the needle and orings but I was wondering if there is another oring I could use? maybe one from a hardware store may work?

Or you could sell it to me cheap!!

We still have a few of those GRP needle o-ring kits left over from the GRP days, if you can't find anything else that works look in the "Engine Parts" section of our website. Part # LOSR2021

The Rod and carb have been improved.

Are these the new GRP Based Engines? I have over Ten Gallons on a tuned .21 Best engine I have ran in along time.

A fellow racer wants to run 20% in his GRP engine...what is the shimming required for the 20%?

grp

He won't need any additional shims. Just run it with what it came with.

He could run it just the way it is from the factory he only needs to add shims if he runs 30% and that would be one more shim to add. I run 2 shims on mine with the 30% just so it does not pit on the piston. If your friend is running 30% and he wants to run 20% he will have to retune the block. I run both the .21 GRP and .28 GRP. I run 6.0 venturis in the .21 for the buggy and a 7.0 venturis in my truggy.
Hope this helps!!!!!!!! :)
