hey guys, I just got a used grp engine. Not sure how much fuel is threw it but has good compression and a new rod and ceramic bearings in it recently. My questions are what plug does the engine seem to like the most. the only pipe I have is a rb 2045 pipe think it will do ok with it? Also what are the factory settings for it. Thanks Im sure I will be asking many more questions to come

thanks for help guys. Here is another twist on my quest for a pipe.
I won a 086 pipe in a raffle at my hobby shop. The pipe was not actually provided by the shop however. Should I see if I can swap for an 053? What will an 86 do for power?

revo, do you happen to have the pipe that comes with the promo kit? They have tested alot, that's pretty much the best pipe for the job. You will have great smooth power and very good runtime if tuned properly.

It's honestly not restricitve at all for the engine. If that had been the case I assure you none of the top guys would have it on the engines. I think anyone that ran the worlds used that pipe/grp .21 tuned.

Revo, I understand 100%.
Not sure why some say it's the worst. A good key is to look at what the best racers have on the engines. If a ofna 053 worked the best it would be on those engines, or a version of it, exp at an event like the worlds.
I have had the chance to test and race several events including the worlds with GRP's top guys. The GRP support crew of course was at the worlds anprovided us with support. It was always determined that was the best pipe overall for the engine and thats what ended up on our cars for the worlds.
Now, if someone told you that was the best and you looked and they had a jp-3 on the engine you would then know that your told that because they were pushing product.
It's a solid pipe that does not dent easy, connects to header without the springs and does not leak there either.

Some don;t notice how it connects to the header, you see that? My email is [email protected] should you have any questions regarding the GRP. You can also ask Adam Drake on the losi 2.o thread.

Revo,
I called Adam Drake and asked him. He said the 2053 is great for the engine. He said make a ton of power and that he actually stopped running the .28 because it would wheelie through bumps to much. But he could not see why some say it's the worst pipe. If you need more power than what that gives ya you may need another hobby! lol....
But I asked the best alternate pipes as well:
Jp-1 for more bottom(you won;t need that)
Jp-3 works well too.

By all means I am not saying you are wrong. I did not have time to read through the entire thread, but I think Adam said it's ok that your engine ran 210 degrees when you asked him.
I have had the chance to race with adam and test several times in preperation for the worlds. He showed me some very valuable information that has helped me since running the GRP .21.
When breaking in my engines( I have 4) none of them have ever reached 250 and when tuned properly will not run much over 200 degrees. The most I have ever seen Adams run temp wise is about 210...maybe. I would think running it at 250 might come at the expense of the engine life. If you race with Adam or in his area let him look at it and he will put you on track. Once you see him tune, it is very easy to replicate.
Again, I may have missed where he told you that.
Take care.

I happen to see him at the JBRL races, even though hes too busy working on his own, and rhonda's buggy n truggy too.. So I rather not bother him at the tracks on race days. But since that I am moving closer, for a job, I am sure I will run into him at Reveloution, Thunder Alley tracks.. hopefully if i am there at right time, right day. I am looking to get another grp 21 tuner engines for spare and backup. but damn glow plugs, why are they so expensive.;

If you saw the track I race on you would laugh at me for using a .28. I mean a strong running .15 would likely suffice. But I want a quality engine and I can't see paying the same price and getting less power. There are also some very large tracks near me too, and I'll be able to uncork her!
