The last I heard on the gold head Reedy engine was "sometime this fall". They're still finalizing some details on the engine.

Ill be going back to ninja
 
This motor is a glorified picco p7R...:cry:

I am really thinking about Switching out the V-spec to the Reedy mill in my RC8... I love my V-spec.. Tons of power and I run it on the rich side and it still has tons of power...

Any opinions on the switch...

I can say that at 250 degrees on each motor, this Reedy definitely has more snap on the bottom end than my VZB

Agreed, the Reedy has Killer bottom end, as good or better than any other 21 on the market. Lacks a bit on the top end tho, vspec def has more up top. I'd say that the Reedy is potentially the best short track motor available. If you have a medium to large sized track, you may want to get it modded to boost the top end.

So now that dudes dyno chart hits the net and this motor lacks some up top...

Innernetz is full of toolz....

This motor screams !

Hey i have a few questions about these engines, looking to buy one, however i have a JP-4 pipe and was wondering how these engines run with thiese pipes ?

Also whats the recommended glowplug for these engines, its usuall about 15-25 degrees celcious here, not that humid, i can get ahold of really only OS and RB plugs easily, and maybe novarossi.

Any help would be appreciated, this is to go in a 808 buggy too

Ok thats good, what about pipe ? will a jp-4 be good ? as its more a mid to top end pipe, so may increase the reedys mid to top while taming its bottom end a tiny bit ?

And what economy have people been achieving from them ? as when they first got seen there economy wasnt the best, as seen at last years worlds with maifield, however he seems to have better economy now ?

i'm pretty heavy on the throttle and run it somewhat rich, with the 7mm restrictor and easily get 9 mins in my truggy

SPEEDSKI 08-09-2009 05:05 PM

My boy is getting 10 min with the 8mm insert in his MBX6. Power really came alive this weekend with a clutch change and an OS 2050.

Impressive, everyone comments on how it purrrrzzzzz!!

We got to race with SPEEDSKI and Nick this weekend in Nashville, TN and had a great time racing and sharing info on the 121VR.

Nick's engine had a little more time than I had gotten on mine and it was settled with the OS 2050 pipe. I believe SPEEDSKI was helping him pit, hardly saw them touch a needle on it.

Myself, I needed to get some more fuel through my REEDY, I think I was at 1/2 gallon on it when we got there. After several tanks of practice and qual's the engine really settled in. Also, I tested an 053 pipe which worked well for me. Once I tuned to the 053 pipe, approached the 1 gallon mark on fuel, the motor came to life.

I ran a 15 min B-main with 1 pit at 7.5 mins no problem. Bumped to the A-main and again pitted at 7.5 min to 8 min easy. Motor never flammed!!

I bought two 121's right when they came out. One about a week before the other one. I ran a gallon of Byrons 30/11 through the first engine and was never happy with its performance. The bottom end performance was killer, but noting up top. I mean, nothing. I ran P3s and P4s with no change in performance, and a 2035 pipe. I had dirt get past my air filter and roughed the crank up a bit. So I put about half a gallon of the same Byrons fuel through the second engine with the same pipe but only running a P4 now. Then went out ran 3 qualifiers and put her through 22min of a 30 main before my receiver pack died. I can honestly say the performance of this second engine is way better than the first. It has the same bottom end snap, but with alot more top end pull. I am only an hour leaner or so on the hsn and maybe 2 hours leaner on the lsn. I really am happy with how its performing. I have a +1 clutch bell I am going to try. If I can soften the bottom a little more and pick up a little bit more topend, I will be real happy.

With the 8mm insert, I can get 9min in a main with no flame out. I think I can push it to 10min once she has a gallon or so through her. The engine is in a D8.

SinisteR, How hot was your good motor when tuned in properly? Mine seems to want to run around 270-280 in a truggy. Motor has about a half gallon on it so I pulled it rather than running it this weekend's race.
