The Aug./Sept. issue of Tuner Performance Reports magazine has a whole ****-load of FD stuff in it. Good reading for both the well-informed and the newbie.

 

nice, ill check it out then.

 

yea I have that issue. Some of the parts I had no idea some of those companies had.

 

who carries the mag? Barnes and Noble?

 

I picked mine up at Books-A-Million. Not sure about Barnes or Borders?

 

I think I saw the articles, is it the one where they highlight the intake ports on the reflection in the rotor housing instead of on the intermediate plate? Freakin' idiots!

 

None at Barnes and Noble and none at Borders as well. At least here in the Bay Area. Anybody knows if you can buy it online?

Why buy it?

 

Thanks for the link. I found this statement pretty funny though it was written on their website.

Feature Editor Greg Hatton said it best; "You have to give the FD owners their due; it takes real guts to drive a car that may burst into flames at any moment."

 

Yeah, I saw that. Hatton probably drives a Honda.

 

is that the only article? Did they talk about anything else in the print version?

Pretty decent article. It's interesting to see that they recommended coating the rotor face to decrease heat transfer.

 

Any one notice that they had the intake arrow pointing to the wrong place on the displayed engine.

 

711 has the mag too.

 

That would be the intake on a periphrial (sp) port rotary engine.

 

Correct, but that is not a periphrial (sp) port rotary.
That is just the reflection of the actual intake.

 

but what i found kinda odd was they put the fd needs 4.9 quarts of motor oil

 

"Rotarians" Haha!

 

good and not good.

"while the reciprocating engine has burning mixture around its spark plug for a nominal 180 degrees (the power stroke) out of 720 total degrees for 25% of the thermodynamic cycle time), the rotary has burning mixture around its leading spark plug for roughly 70% of the cycle time"

This guy gets his crank cycles and combustion cycles mixed up. The rotary power stroke is 270 deg out of 1080 (he forgot what he said on pg 1), which is same 25% as piston engine.

Also came up on cooling issue ... "The rotary also has 1.5 times as many milliseconds to transfer heat from the burning mixture into the oil and water." This is like saying a piston engine has 1.5X more waste heat losses at 3k rpm as it does at 4500 ... nope. Rotary does have more suface area for heat loss, as he noted.

Also think he gets messed up when peeking at rotor faces through spark plug holes. 35 btdc on the crank reflects a rotor that is 11.7 deg btdc, and the rotor face should appear to be near tdc.

 

last honda (acura) I saw at the track, Texas World Speedway last weekend burst into flames the sole FD (mine) remained running after two lapping days in 100 deg temps

 

given a break at least they got the right region and didn't point to the water jacket

 

I got a copy at walmart.

I thought it was a good read actually. Nice pics of stock & modded FDs. Little to none of the import tuner hype bullshit.

 

I now see his hot plug point, yup it's shared by 3 chambers, so 3x the heat cycle vs piston engine.

 

TPR just copied an article that Jim Mederer from Racing Beat wrote about the comparison of the 13B-REW and the Renesis

I guess they got permission from Racing Beat ??

Wow, that is the exact same article word for word

 

Typical cheapshit magazine giving others a bad name by just reprinting others' work, instead of actually doing some research themselves. Geez...
