It has an excellent bottom-end & good mid-range. All-in-all I really like the motor. I talked to Adam at AB Mods about the timing specs of the motor and he says it's really similar to the V-Spec. It dyno'd at 1.5hp & 56oz. of torque. I'm looking forword to heading to Whitehouse Hobbies in Tennessee to race tomorrow & do further testing.

:confused:Question(?): I have seen the engine apart (pre-production,) on RCTech(the pictures were from France) and the piston had 5mm bypass holes - does anyone have any idea why they omitted them in the final product? In my experience, they have been known to boost power & fuel mileage.


Well i know that there is supposed to be another version of the Reedy coming out. I'm not sure when, but it is supposed to be a 'more equiped' version. This may be a feature of that version of the motor, it will essentially be a 'Team' Version of the reedy.

There is a video on Youtube that has like a first loook at the 2 versions of the Reedy, one with the dark blue head and one with like a gold head. I don't remember how i found it. I'll keep looking for it and post it up....

I think I found it for you.

megasaxon 07-31-2009 11:46 PM

yep thats the one, its possible the 'Team' version may have those bypass ports, hoping for maybe coated crank os some sort, looks pretty sweet with the gold head and black crankcase.

reedy now has glow plugs.

wfo 08-02-2009 04:40 PM

Ran my REEDY today
 
Ran the Reedy today tuning window seems to be small. P3 plug, Asso. 2035 and stock clearance. It ran pretty good on the bottom but seemed to tail of on the long straight. may be a short to mid track motor. temps were about 240 then i richend the bottom 2 hr and top 1 hr and it came down to 218 still has about 3/4 gallon on it. i did notice at one point that the case was cooler then the head. i wonder if this is why some people are getting a higher temp reading then they are ok with? it had good smoke at 240 temped w/ 3 different exergen guns ...The ninja i sold my friend w/ 4 gallons killed me on the stright I wish it rocked the top end i would be...:nod:

WFO you hit the nail on the head on this engine with its power band and needle sensitivity. I have been doing a lot of testing on this engine lately and have experienced thew same thing on and off the dyno.

The engine makes for a very good short track engine. And for the price its a good deal IMHO.

I race on a medium length track, really really good motor in my truggy, our straight is pretty long, but not long enough enough for me to really run out, just under the threshold. I'm sure with a good modding and maybe more of high-end pipe you can get enough top end for those large tracks!

Brandon Melton 08-02-2009 07:46 PM

WFO- The motor really wakes up after thorough break in. It will run cooler as well making better power after at least a gallon through it, you should be coming up on that. But don't be afraid of some heat. 240 barely gets my motor close to where I want it to be. I can tell you at 218, it would be very dissapointing.

Most of the team has found that the P4 or the OD 97T produce more top end power (Reedy plugs just released, but compare to P3 and P4) than a P3 does.

I can say however that even at 260-270 degrees, the motor makes great power but never has that "screaming" sound some are used to (your previous ninja). Just because it isn't making as much racket, doesn't mean you're not going as fast. I run a 16 tooth on a RC8 and never get "pulled on" down the straights. I'll take the drivability and smoothness of the engine over eye opening top end anyday.

I have almost a gallon through the motor and it just gets better and better. Ran all weekend without a flame out or a stitch of trouble. This is the smoothest motor i have ever driven. I was getting "pulled" in the straights but, i could easily go up a tooth or two on the clutch bell. I was getting about 10-12 ft on the other trucks coming outta the corner but they would catch me at the end of the straight.
Its really quite odd the pitch that this motor has. it sounds like no other motor and i like it!

What a great engine. I took it out to the CRCRC shootout this past weekend and had zero problems the entire time. Idles forever, and really was not that hard to tune, using OD 97 plug, nitrotane 30. My brother and I were running the same car. He in sportsman and me in pro. We were back to back in most of our races and the engine just kept going. I tune for performance and the temps were only in the 225 range. I have run werks, OS, nova's. I really like this engine.
I sealed the carb with racers edge sealant and always used a heat gun before starting. Used the thunder tiger 2035 pipe.

wfo 08-03-2009 12:20 PM

Thanks B . Melton i will try a plug change and go up to a 14t clutch bell The motor has every thing else !!! I guess im not used to a motor running at 240-260. Ill know in about a gal. if the Reedy is the real deal...

Good statement.. And it all leads to "SETUP". The Reedy is very similar in a lot of ways to a Vspec.. bore/stroke/crankshaft design even down to the engine timing which is close as well. This is what gives it its smooth power characteristics. With some coaxing/internal modification i have been A LOT more impressed with this engine.... And for the $ the Reedy is without a doubt a top contender and will get the job done. ESPECIALLY if you have your setup on point. But as with ANYTHING setup is KEY! :nod:

SkarTisu 08-03-2009 09:58 PM

Adam, did your mods change the drivability of the engine? My V-Specs always hit like a light switch off the bottom when I tuned them nice and crisp. The Reedy engine has been SO much easier to drive since I've switched over.

Although the engine now has more power down low then stock it still has a very "linear/smooth" feel. It no longer comes on hard and falls off on power so quickly in the higher RPM range.... Which makes it have less of an on and off switch feel.

REEDY21 AIRLEAK?
 
Just curious, anyone out there who is running the reedy, and has had probs
with airleaks from carby,where it bolts to crankcase? some guy`s here in south oz, have had an issue with this, after purchasing from factory..they
say that the carb insulator does not expand very well, within carb housing, and apparently causes it to leak from this area? Any feedback appreciated.....

Bigedmond 08-04-2009 01:57 AM

I just ordered my Reedy, and i am going from GRP's so i should notice a huge bottom change. I am just worried that 2 years of GRP tuning has messed with my head to much.

yea you have to seal the carb gasket to the block and the carb to the gasket. I use the Racers edge carb sealant which is just RTV

ok guys im sorry to say i have followed everyones posts about this motor, thanks brandon, sealed carb sealed backplate tried to tune her and she just wont keep a tune 97t plug odonnells 30% and its not bad gas speed ran fine with it, two good laps temps hold two more they skyrocket up richen it up temps keep on climbing, richen more temps keep going up. called associated they said send her back, so lets see what happens????

yea kinda sounds like you got a dud, first one i've heard of. Send it in and i'm sure they'll get you hooked up with a fresh one

SkarTisu 08-04-2009 08:56 AM

I wonder if it was super lean on the bottom and fat on the top? Seems like when I've heard of people having trouble like that, the balance of the two needles was way off.

used brandons needle settings ls and high side but richened them just a bit prob two-three hours on both just too be safe, then started leaning out a little at a time temps only held two three laps then sky rocketed, if i fattened lsn it just kept rising and it still had plenty of smoke, maybe just got a bad one, im not mad shit happens ill call it friday monday motor:lol::lol::lol:

Bigedmond 08-04-2009 10:26 AM

AE has great customer service, so they should be able to resolve it quickly for you.

Brandon Melton 08-04-2009 12:21 PM

lucky2, sorry it didn't work out, they'll get you fixed up. If the carb sealed ok and the backplate,the only other thing it could be is possibly a bearing failure, if the bearing fails, it can suck air, meaning that you can keep fattening it but it leans out through the bearing.

SPEEDSKI 08-04-2009 05:41 PM

Brandon, any word word on the Team Edition with the gold head??

jamminx2kid 08-04-2009 05:55 PM

+1 i also want to know if there will be a gold head edition mabye it will be a screamer like the os:nod::confused:

I have not heard any word on a release date for that motor.

skidooracer 08-04-2009 06:44 PM

jus curious did anyone have any problems with the idle screw backing out on this motor ?

i haven't had that problem, just would need a new o-ring on it and should be all set

SkarTisu 08-04-2009 09:33 PM

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

wfo 08-08-2009 04:06 PM

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

FactoryRacing23 08-08-2009 05:03 PM

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...

Nick

InfiniteMotors 08-08-2009 05:27 PM

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