About 10 days ago, I purchased an S7 for my buggy and a Rody C5 for my Slide. We wont speak about the Rody, since we all know that it is a baddass sonuvabitch. This is more for the unexpected surprise I got with the the S7.
I was hesitant to get the S7 due to the fact that so many others decided to go with the WS7 II. But the price was 100.00 difference, and I dont race too much with the buggy. Brought the engine home and did a visual inspection. Top notch, just as the others I have gotten. Bear in mind that this is the first Non- Modified RB engine I have purchased. I planned on running 30% in this engine, so I added 2 .1mm head shims per RB's recommendation as well as switching to an RB7 plug. I followed the break in proceedure per RB's chart, which reads as follows:
Start engine, and let idle for one tank of fuel on preset factory settings. These settings are quite lean to facilitate ease of run-in. Engine fired on the first hit of the box, and did not stall once, for the entire 20 minutes it sat at idle. Temp reached 180. Let cool. Richened the HSN 1.5 turns and the LSN 1 turn. Ran at WOT with these settings, which still barely let the vehicle run due to over rich conditions, for 3 tanks of fuel. Verify temp is approx 160. Leaned HSN 1/2 turn and LSN 1/4 turn. Ran again for 3 tanks of fuel, temp was approx 180. Leaned HSN 1/2 turn, did not adjust LSN. Ran again for 3 tanks of fuel, temp was maintaned at 195. Tuned for max power, engine run-in complete.
This engine, once tuned, is amazing. It is slightly more powerful on the top end than the RZ, and has far more low end grunt. ll the while, temps running about 215-225. Engine starts the first time, everytime, and maintains idle indefinetly.
I would strongly recommend this engine to anyone. I have been told that other Nova based engines, such as the sirio .21pro, rex p5, ect.... are equally as good.
Overall this engine earns top marks in my book all the while coming in at a bargin basement price of only 215.00
