Really? It's a good power option? Good to know.. I like those pipes - at least the price!! Can probably find one cheap..

I wouldn't say it's the most powerful pipe the short 9901 had way more but it made it very thirsty but the 2035 i find give it a more drivable bottom end with a good mid and top end power i've tried most of the other pipes people are saying to use and i keep going back to this one as it has the power were i want it in the power band... for example with this pipe in my truggy with an 8mm restrictor i still only run 1.0mm springs but with my toro nero i had to run 1.1mm to get the same feel i could even go to a 7mm but i like having that little bit extra there if needed... So yer try it you might like it... One of the other guys that runs the same engines with a different pipe had a drive of my truggy on the weekend didn't like it, so it's not for everyone..

I am still running the 801 pipe. i have a Oval carb insert on it and geared it up a tooth on the clutch bell and that made it much more controlable in a buggy and still able to get 10 min with it. :nod:

Just curious , but, what temps are your A52 running at about 1/2 -3/4 empty ?

Rcrenew 07-27-2011 03:29 PM

Temp after a race run for us with the outside temps in the high 90's is 260 deg. These engine like to run on the warm side.

Thanks , that`s just what i wanted to hear ..............temp here was high 80`s today and was tuning and was about 240

rider313 07-27-2011 05:00 PM

i have found my temps are as high as 275*f on a great tune. If its got great power and nice smoke dont worry about temps. to many factors to tune for temps.

Bruce53 07-27-2011 05:21 PM

use the temp as a ballpark , A52 puts out good smoke , so going to lean her out tomorrow , should be fun ..............

Has anybody here run a Jammin JPX 21 or Picco P7 Evo 2/3, and if so, how do they compare to the Argus?

I had the Nosram 21RR - a Picco-built Jammin twin(along with the LRP Z21X), and it was awesome with the 2063 pipe. They are now being sold off for really good prices, I guess because LRP's new race engines are being supplied by OS.. I have an Argus NIB waiting for break-in, but due to summer holiday and having too many engines in general, haven't gotten to it yet.. Anyway, I would be curious how the Picco engines (not the 3-ports, Boosts, etc.., but the P7's.. - Nosram, LRP, Jammin, Orion CRF, etc..) compare to the Argus..

Received an A52 Moded
 
I just received an A52 moded from RBmods. This thing has beautiful work inside. I Installed it yesterday on a Tamiya truggy (TRF801Xt) with a EFRA 2081 pipe and fire it up for the first time.

It took forever to start the engine. I never had a harder time starting an engine for the first time. The pinch is unreal. I finally started it but I had to heat up the head remove the spark plug put some fuel from the top and spin freely the engine while hot and lubed with the bump start to loosen it up a little. Once I did that for about 30 sec the engine loosened up. Put the dynamite plug in and it fired up. The LS needle was too rich so I leaned it out a little.

I let it run the entire tank (150cc) at idle. This engine did not quit running at low idle for the entire tank. That was 40 minutes at idle on the bump start... Yes that was 40 minutes at idle on one tank. I thought that it would stop running, but it kept on going. Temps never got over 185 F (very rich LS needle). I did not want to get the temps any higher for the first run.

Today I will run one more tank on idle and then lean it out and load the engine lightly by driving it slowly.

I was speechless on how it purred. Keep in mind that I am comparing it to a Werks B6 that I have on my buggy. This will be interesting as so far it has been very promising.

I can’t wait to see what the 2081 and the performance mods have done to this engine.

The Argus/ Alpha motors start up easier than any engine I have broken in. Yes they are tight but they will hold the pinch longer. I would advise not letting temps get below 200 deg. put a can coolie or foil around the head.

+1 on the heat, especially on the first fire up. I dont like them to get below about 250 - 266F. I have run in 8 Alphas and now 1 Argus (love it) and these things love the heat. On a winner with Argus. Running APLUS 0801 on all.

I run it yesterday on at the track after 4 tanks on the stand. While still rich it made the truggy a rocket propelled missile. Gargle, gargle a little on full throttle and when it cleared it launches. The Dynamite EFRA 2081 just lights up. Great pipe and great engine.

The problem is I have no reference for this engine without the modifications. So I cannot comment on how this engine performs without the mods.

In general it seems to have almost a linear response (except top end because is still rich), have plenty of torque to clear big jumps and really cheap on fuel. This is the first time that I actually run the truggy with on the track to the point where I started to get bored with it. I did not time it yet, but it was sure a lot longer than 7 minutes that I was geting before on my AE .28 pro (and it is still rich). I will time it next time and report actual times with this pipe.

In truck it should happily go 10-11 minutes once broke in and tunned right. Dont be afraid to see the temp around 250-260. They love the heat and aren't harmed, your harming it be running it rich. I can tell ur still in break in but once u get a lil more in it let the thing drop its ..... . These engines are taiwan based like alpha, go, xpe euro. The taiwan engines love to see the heat, they run great at 220 but lean it more. If its to much power tame ur trigger finger. Ther power will always be there. Just look for a nice thin line of smoke in bottom and top end and ur fine. You will love this engine.

Well, I've run my fair share of Picco P7 Evos and JPX's and I just recently bought a Clockworks Argus....to compare them, I would say the Argus is as strong as the Picco everywhere except at the very first (and I mean first) hit of the throttle....the Picco just hits harder but the Argus has plenty of bottom end :) I would say that the Argus has a higher top end too, but pretty close in overall power....I've been very impressed with the Argus :D

Not to mention the Argus does quite a bit better on fuel :nod:
