REDS Engines (Mario Rossi)

I ran a R5T last season in buggy. Tons of torque. Too much for my track and driving skills most of the time. Going to sell it and get a W7 this season. Looking for bit smoother of a power curve. That new motor will be a hand full to handle in a buggy. Unless you’re Mayfield I guess. It seems by the numbers that it would be best in truggies. Or I could see it being good on a large track where you can let it rip on every corner. The dyno chart I saw on it was insane.

When this is so we have to adapt our driving style.

So, on that track, on that day, the WRX made the buggy a bit less consistent and hurt the qualifying times. However, I am sure that there will be people who will love it in a buggy when the conditions are right.
I was very impressed with how well it ran and the brute force power that it produced. The buggy was a rocket when the traction was high. Can't wait to run it in the truggy.

New to me r5r
Hello, I just bought my first REDS engine r5r combo, is the hard to reach glow plug normal on these engines? Its seams as there isnt any room for glow ignitor to clip onto glowplug. Sorry for the weird question this is my first REDS, Ive never had this issue with any other nitro engine.

If on a large/fast track, run it with a 7mm v2 venturi, top end will scream. Expect 8-9 mins runtime average. Excellent mid price engine
#2094
2104 will work well
OS plugs are also a direct fit

For truggy, the WR5 is the 5 port version of the WR7. It has all of the upgraded components, but produces more instant power delivery due to its 5 port configuration. It replaced the tried and true R5T Team Edition, which had been the primary truggy engine of REDS' truggy racers. The "HE" version will provide increased fuel mileage but at the expense of some power. The R5R discussed above is also an excellent choice for the budget-minded truggy racer.
The R5R is a great value for the performance provided. It is a 5 port engine with some, but not all of the high cost upgrades of its more expensive brothers. It has a bit more raw bottom end grunt than the WR7, and will run with most any high-dollar engine down the straightaway. It is a very popular engine due to it's great performance to $$ ratio. It is good in buggy and truggy.
The newest engine is the WRX. It is the most powerful engine that REDS has ever sold. It is for the racer that wants the feel of instant and huge power delivery (Think Electric Truggy). It will work in a buggy if you have tons of traction and/or are a great driver with excellent throttle control and car control. Otherwise, I personally would recommend this engine for truggy. It has insane power! It has all the same Diamond coated parts (DLC), ceramic bearings, and horizontal carburetor as the WR7 and WR5. It also has a new, and even lower CG designed cooling head.
All of these engines are winners! You simply need to pick the one that fits your budget and your needs. Feel free to message me if you have any additional questions.

I would like to see what a modded WRX would do up against a 28-8 or something.

I have a few spare glowplugs (P5TH Picco) from my last engines. Are they any good in REDS engines? Same as T5C?
