I am unquestionably a Lexus fanboy for life. But when comparing the Lexus 2UR to the Ford Coyote, I feel like the two are pretty well matched in power and efficiency.

Stock, the 2UR puts out 468hp with direct injection. The Coyote puts out 435 without DI (please correct me if I'm wrong.)

another

The IS-F's 2UR can push 500 crank horsepower with just intake, exhaust, and ECU tuning. People have regularly gotten 410whp.

Guys with newer Coyote engines have pushed 420whp and some claim 450whp with bolt ons and some extra stuff like bigger throttle body and maybe cams and head work.

The RC- and GS-F 2UR, if it follows the same conservative factory tuning as the IS-F 2UR, should easily be able to put down 450whp with the same bolt ons as IS-F modders, easily beating the 100hp/liter with fewer mods than a Coyote engine.

Side note, if you've tuned your F, what are your power numbers?

Now, I know because of weight differences performance numbers are going to be a different story. The Lexus cars are a lot heavier. That's just fact.

Another thing to consider is the ratio of torque to horsepower is different in the Coyote. What that engine sacrifices in hp it makes up for in torque. It's tuned differently for more off the line jump.

To wrap up, I do want my pride in Lexus engineering to win out and the 2UR to be a better motor, but honestly, I think they're pretty close to equal, long-term quality aside. I am genuinely thinking about buying a Mustang because a two-door V8 with a manual is just killer.



But I'm interested in hearing engineering knowledge from people who know more than me. What else might set these engines apart?

 

I believe most RCF are dynoing about 390rwhp in stock form. The RCF engine is more complex and efficient than the ISFs, so don't expect huge power gains. With just exhaust, some are getting 400-410. With headers, intake and tune, maybe in the 42x rwhp range. I'm not sure if anyone is changing out cams or doing headwork. Some here have cross shopped the Mustang and RCF, but not many. The problem is there is an entire car surrounding the engine and Lexus has it all over the Mustang as far as build quality, reliability, comfort and features. If none of that matters, then the two engines are pretty well matched. I haven't driven a new Mustang, but I heard good things. The Mustang has more low end torque, but the RCF breathes better up top.

 

442/395 full bolt on all RR Racing Mods
intake / drop in filter / Ppe headers / Borla exhaust / rr ecu tune.

Weight and hook up is an issue. I have the usrs, Tom bracing, and Penske coilivers.

Ive never seen a mustung other than in my rear view lol

 

How much rubber you got out back?

 

442whp is probably close to 510 crank yeah?

 

275 in the rear.

 

Just went to 305s in the rear and they transformed the car. traction is no longer an issue

 

Which tires? 305/30 or 305/25?

 

2018 mustang gets DI/PI and is now 460 hp and 420 torque

 

Bro, I stayed with 19s for ride comfort and just went wider. I'm running 305/30/19 Michelin PS4. Its a better tire than the Super Sport and has a better wear rating.

 

Wow, impressive. Did they increase the liter size? The compression ratio must be off the charts.

 

Still a 5.0. It's probably spec'd very similar to the 2UR.

 

Still a 5.0, when paired with the optional 10 speed it should blow the rcf away. Every gear ratio is more aggressive as well as the differential gears, it ran 0-60 in under 4 seconds with the optional 3.55 gears. In stock form it's a menace, should be able to hit 500+ wheel with bolt ons and e85 and 700+ with boost lol

 

simply outstanding. Lexus has the hp down but the torque is 22lbft shy of GT's 420lbft. At most 398lbft from in the LC500. The Lexus 2UR-GSE in race spec I believe puts out around 540hp. Not sure the torque. I'd wager it's tuned a bit more for economy and longevity in current road going Lexus's equipped with 5.0.

 

Yes, but it is still a Mustang. After driving quite a few 2017 Mustang GT convertibles and patiently waiting for Ford to announce the 2018 ordering information we decided to take a look at other options and stumbled across the RCF. Lexus was not even on my radar. The Mustang is a great car, but in my eyes it isn't even remotely in the same league as the RCF and definitely built to a much lower price point. Test drive a few back to back with the RCF. Other deciding factors for us were that you see Mustangs everywhere and the continuing mechanical and dealer issues I see people reporting on the forums.

My Corvette and even my mostly stock 1989 Turbo Trans Am are quicker than the RCF, but on most days I would much rather be in the RCF. The best solution would be to have both the RCF and a fun V8 with a manual in something else.
