I will second that. Although "flameouts" can be a number of issues, these motors tolerate everything. They have a wide band of tune, meaning, even if you are out of tune, or your tune changes during a long race, I have never had it flame out. They can run upwards of 300 deg without issue. Great motors, and you cannot beat the price.

As far as 10mins, a motor can only do so much. I've ran the D52 and R8 also, they get great fuel mileage for me (I can get 10mins with the R8 in most tracks conditions), but my experience mileage to a large degree has to do with conditions (ie size of track, long straights, etc) and throttle finger. if you mash full throttle all the time, you are not getting good gas mileage.

Rex does have a couple of things he can do mod wise to increase fuel mileage, so you can check into that too.

Hope that helps.

Thanks for all the feedback. I think at this point I am just trying to decide between the R8, D52 and R83.

I am running one for the fist time this weekend. If you know anyone that has an Alpha Dragon it is similar and should be powerband wise. I also order my engines from the factory with double sealed front bearings as I prefer that.

Can't wait to hear how it runs in "race" conditions! Why do you like the "double sealed bearing" up front better? I am assuming it keeps more dirt out?

Yes, it keeps more dirt out. The Argus bearings are actually very good and last a long time.

I ran the Argus R83 3 port this weekend at the Mnrc rd 1 at the Motodome in Staples Mn. I lapped it in and broke it in on the bench at about 4 tanks on it. I didnt run it in the car before much just a bit on the box for a couple minutes. Went to the track and took it easy for just a couple tanks to learn the track, barely touched the tune. It was making good power at just over 200 deg. I leaned it a bit in the morning practice and ran it no hotter than 240 deg all weekend.
I ended up Tq in the Buggy C-main and they were down to a E main. I won the C and ended up 8th in the B main which for me is a great run, there was fast guys from 5 states and Canada there. (and I race about 3 times a year haha)

My impressions of the engine:
It has more power than I thought it would but is still really smooth. I had a team guy of mine that runs the R8 run it and he really liked it, still fast but more throttle control on the bottom. I took some vid of Hunter running it in my car I will get up soon. Hunter also won the Buggy A with his R8 so congrats to him!

Rex, what pipe did you run on the 3 port? How was the run time?

22Racer

iTrader: (67)

Here is a video of the 3 port, I am running a APlus 0801 pipe, 30/9 Byrons fuel. Still running a somewhat rich tune as it never got over 240 deg. all weekend.
This is actually my car with Hunter Holmberg driving, Hunter ended up winning the A main Sunday with his R8 that he ran all last summer.

I've got about six tanks on my r83
With a 0801 pipe I had Rex lap the piston in for ease of break in I will be running it tomorrow

Got my R83 on the track today in my old Mbx7 practice car. Super happy with its power. It has plenty of torque and power for buggy. I mostly run a R8 modded in buggy but I will be using this R83 from here on out, that's how much I like it.

Just ordered the R83 from Rex to add to the modded R8 in the stable. The R8 is so good that I had to try the R83 as well! I have issues...
