2013 Scion FR-S

If only the price wasn't so high... :/ (for what it is.)

Would've waited and gotten this instead of my Chevy if MSRP was in the low 20's...

 

I'm guessing you didn't know Toyota bought Yamaha for their engineers and to buy cylinder head designs developed from their motorcycles. For future reference Yamaha = Toyota

 

On the engine topic - I don't think the designers are an issue anymore, all the manufacturers have copied one another to the extent that there's little difference nowdays.
When 16V became the hot topic back in 1980 it was Honda who led the way, not Yamaha, Kawa or Suzuki and all current 16V head designs are Honda (Pentroof design) copies.
In fact Yamaha was the last of the big 4 to switch to 16V and they used the Honda designs but added T-VIS, powervalves, ACIS etc

To add injury to insult - Alfa and Ferrari were using mutivalve boxer engines long before - in the early 70's (73-) the Alfa 33 and Ferrari 312 motors were already legendary

In 1979 Honda raced the 1st 500cc 4 cyl 32V engine which actually beat all the 2 strokes in Belgium in 82 - it is THE craziest engine you will ever hear

I love boxer engines but hate the VW, BMW, Citroen and Porsche versions, the Alfa, Ferrari and Subie versions are a different story altogether so don't put them under the same heading.

From 1960-1990 Boxer motors won LeMans more times than anything else

The thing about boxer motors is balancing - they have the best balacing and harmonics of all the common designs.
At any given displacement a boxer motor using similar pistons, cams, heads etc will always make more torque than a straight engine.
V motors also have better balancing than straight motors but not as good as a boxer.

Another plus on boxer motors is the layout - it's usually easier to get at starters, filters, carbs, alternators, dizzy's etc but changing heads etc isn't supposed to be done in the car

There are pro's and cons in every design, that's what makes engines so interesting

 

Hey, Cliff! You need to cool off buddy. The only words I've read here that seem to be frustrated are you replies to me.

When you say things like "you just can't seem to let this engine thing go" or start referring to my opinion you've crossed the line. You're now getting personal.

Yours is a classic example of people on the internet adding tone an inflection to what are otherwise sterile words in a vacuum.

 

Kev, I'm looking for the article, but I'm pretty sure Yamaha came up with the pent roof design for their late 1970's motorbikes. Circumstantial evidence to support that (and not Honda) is that during the 1980's thru the 1990's Toyota had more twin cam pent roof motors than any other manufacturer. And that is irrespective of whether they were 16v 4cyl motors or not. Building on those advances toyota was able to squeeze out 100bhp/L down the road. I think that has only recently been matched (but I can't remember by whom). Honda, on the other hand was still using SOHC 8v engines will into 2001.

 

Cliff there was clearly some sarcasm there. But whatever, say there wasn't. I don't care. I still think you thought that the airing of my original opinion was somehow a slight towards you. It wasn't. Things devolved from there.

I agree. This is a losing argument as it is.

 

We all get mis-interpreted sometimes and opinions are just that - opinons
I'm not sold on the styling and I'd have to throw one around to see if it suits me
Now put an LFA in the same spot.....

Mafix, no I'm not talking about crank balancing, rather the "balance" of the motor on the engine mounts and the way that it moves under acceleration and deceleration.

What's really interesting is that in a 4 stroke engine - the magic # is 3
Engines with a multiple of 3 have the best phasing between compression strokes and a motor of 3, 6, 9, 12 cyls will always make better power with a turbo/s than say a 4, 8 cyl motor (provided the turbo/s is plumbed correctly, -firing order wise)
The reason for this is evidently the pulses to the turbo/s are more even which leads to better spooling and higher turbine speed.

 

^didn't know that.

 

Didn't I already? Fucking Christ, I'm unsubscribing from this ridiculousness.

 

Whatever.
