just an update ...been slow going on the break in ....rain here sucks ....got another 2 tanks through yesterday ...still no issues at all ....still the same o.d. 97t plug for 4 tanks am gonna try and blip a few more tanks through today if rain holds off......will have a funny youtube video up here in a bit ...no surprises yet ...this motor seems like it will be everything people say it is .....with all the time on my hands ...i may even go ahead and swap out the rear and front bearings with some tko's after about another half gallon ....later

Anyone know if the GRP .21 non-tuned takes a turbo plug or standard? If its standard any problems with changing the button to the tuned turbo version?

standard ....and nope get a turbo button ....

i think that the button is made into the head on the silver head engine so you cant just get the button and change it, you would need a head to make it turbo.

ive never seen one ..but i found this listed as a hop-up for the motor ...so im not positive ...but it looks like you could just but the button on there .....it also says under the description ...that all the parts from the tuned version will bolt right on so can get the tuned feel if you wanna upgrade your standard version

ran my grp yesterday, and I think I found a problen with it that may have been for a while. I have noticed it has been hard to start lately. I was having to plug the stinger to get fuel to it. But I noticed after doing that there was some fuel coming out of the fuel nipple area. So I tightned it down and man does this thing run much better now. It is a rocket now and runs great.

For most instances I would agree that the 'Non-tuned' would be just as good or money better spent for club races. I saw them listed on Ebay and www.RCLiveChat.com for $194.99. I wish I had some extra cash now you know!! lol

man this looks like a great thing for the customer ....and they allready lowered the price everywhere on the motors and combos .....this was copied and pasted from neo buggy ,,,,,,,

GREAT NEWS FROM GRP FOR 2009
WORLDWIDE GRP’S PRICE REDUCTION PROGRAM

This program will be launched officially by GRP starting from January 2009, to contribute to facing the serious worldwide crisis which is involving basically all sectors.
Our idea is to make available on the market, all GRP products of our Tyres, Engines, and Gadgets lines, with the best quality ever, at very much reduced prices compared with our 2008 price list.
This price reduction is possible by reducing to a minimum our margins, by removing some steps in the traditional distribution chain, and by accepting a reduction also of their margins by all those who will agree to our program.
In this way we intend to widen the range of end-users, who will be able to purchase now, at advantageous prices, our top range products. The main points of our new GRP program are as follows:

- Optimization and development of our current production unit in Guidizzolo, with a consequent further increase of our quality product.
- Equalized retail prices all over the world.
- An average retail price reduction by over 40%.
- Purchasing of our products in all the hobby shops that will support our program.
- Purchasing of our products from the new official GRP’s e-commerce.
- Direct purchasing at race events whenever GRP’s staff is present.
- Direct Technical Assistance on behalf of GRP, for any eventual technical problem under guarantee, and for the standard engine maintenance.
- Direct Technical Assistance at race events whenever GRP’s staff is present.
- Direct Technical Assistance on-line on behalf of GRP.

All new retail prices will be published very soon on the new GRP’s website, together with all numerous novelties foreseen for 2009. Here some anticipation:

- New .21 carburetor which improves fuel consumption and eases its carburetion.

wonder what that does for Horizon?

These GRP motors have really impressed me. I will be picking up a powerhouse modded non tuned version in the next month after seeing/driving one last night. They are super smooth motors that have alot of power. And yes the head on the non tuned does not have a button so you cant put a turbo button in usng the same head, which there is no advantage of doing anyway.

i would think it puts them out of the loop ...awesome ....motors cheaper ....freakin awesome .....they have droped all over the internet

man why do the list the turbo button as an upgrade ...i quess you would have to get the gold head with it ....let us know how the grp from mark runs ...he has my extech.24 now and i cant wait to get it back ...should be a screamer at some of my larger track races ....

If GRP is not anymore part of "Horizon family" i think it will became hard to find them in the States. Am i wrong?

they will be available from grp amain carolinas rc ...i mean read the post i put up ...they are just doing away with there larger distributor ...as far as i could tell from what they stated

The motor runs absolutely b-e-a-utiful. like posted in the powerhouse thread we went to ohio to run 1/8th buggy last night and he ran the GRP. It was brand new with very few tanks through it but tuned in in like 1 maybe 2 minutes and held the tune all night. The power delivery was so smooth and controlable but was super fast at the same time. It is really tuff to get into trouble with this motor due to the power delivery. I got to run it for a while and i'll tell ya what, after talking with Mark about better engines he and i both agree this is pretty much the best motor so far in terms of tunablility, drivability and longevity that he or I have ever owned. For like $260 bucks you cant beat it. I think it is better than the tuned and for less cash, its basically a steal. I got atleast one coming my way.

Yes, now Amain is selling the old GRP engine at a lower price... But for the new engines, small distributors will be able to make a better price than a big distributor as Horizon? Just incredible
