Sorry I missed the question. I have a race mod and a turbo mod. The race mod is good but the turbo mod feels like a completely new engine. I run it in an 8T 2.0 so I wanted a little more torque and powerhouse did exactly that. There is not much on the track that I cant outrun. The turbo spools up quicker and revs higher. It runs best with the 053 pipe and when I get the tunning right I get 11-11.5 min. I ran a .21 tuned version last year so I am very familiar with the GRP engines. The powerhouse engine is far superior, like night and day difference. Mark at powerhouse is the man.

053 is a great pipe for this engine. Much better over the GRP 2053.

hey guys, just dropping because I have a quick question,

One of my friends bought the .21 rally tuned engine for his truggy. I really can't find any info on that engine and I was curious on how it preforms compered to the .21 buggy tuned,

Has anyone else heard that GRP is shutting down?

i heard that mario was leavibg grp which raises the question will grp still be making these motors ?

Are these the o-rings for the carb restrictors? It seems like every time I take out the restrictor the bottom o-ring is stretched and won't go back in.

This is what I just found on Mario leaving GRP.But can't find anything on them ckosing.I hope not I love the engine's.As long as there production stays the same why would they. Neobuggy has a email he wrote to them on there site.

does anyone have Alan Burton's email?? Tried contacting him, but nothing....

they arent shutting down ..they are going to streamline there distribution chain to cut costs and pass the savings on to customers ..they will probably be with horizon losi for another year ...mike truhe is still running grp and has signed up to do so for the rest of the year ....about 2 months ago they made a statement on neo-buggy iluding to the fact that this is what they were doing....go to neo buggy and search the news section and type in gandini ....you can folllow the progression ......

how about the engine? will it be the same power as the rossi tuned ones? how about the new product that already breakin by mario rossi, thus the production continues?

on the "rossi-tuned" version i mean the only difference in that and the standard motor is port-timing exhaust-timing and crank size .....also that the tuned version has the nice coating and treatment on the internals ...its not like he laid hands on them and did anything to them ....inmho .....mark at powerhouse rc performance ...has spec'd out each motor and found this to be true ....check his thread out here and search through the last coup,e of pages ......

i few pages back he goes into more detail about it

Ok so i had to get on here and say that i now have about a gallon on my tuned .21 and at first was happy with the motor i was running a jp 2 pipe and i felt the bottom end was awfull so this weekend i switched to the dynamite 086 and all i can say is im not happy anymore im completely in heaven this mill has so much power it unreal and 12 minutes run time with the 6 mm restrictor also temps are starting to drop and its really coming in to its own so i dont know if the jammin pipes bog this motor down or what but the dynamite pipes are a dream for this engine

I got me a .28 truggy tuned motor jsut got it and what after run oil would you guys recomend for it the last nitro cars i had i never used it, so are they pretty much the same or are some brands better?

I raced my tuned modded .21 this weekend it has just over a gal on it. During the quals it was running 220's then after the 25 mn main it must have. Broken in completly because power was up and when of came after the track after 25 min it came in at 175. I was suprised and so was my pit guy. I am having one issue that I need help with. After comming down the straight I hit the breaks go into the 180 and stab the gas and it bogs for just a sec. I changed the clutch shoes and springs. And it still does it. I am thinking it's a lean bog but it runs good. Good smoke and good power just this one area where power is not there 4 a sec. Any ideas top of bottom to lean to rich. Thanks.
