Last nite was damn cold in Toronto.
We hit a record breaking low of -40C.
As per this thread
https://www.rx7club.com/showthread.p...cold+air+power

It's 1% of power for every 6C drop.
So having amibent temperature being 20C, -40C last nite was 60C difference. I raced a stock ITR before and was even unti 180kph. So I am guessing I have 180hp. With the 10% increase, I have close to 200 hp to the eshaft....
No wonder when I hit 5500rpm last nite, the car pulled like a ****!

 

but the car you raced was under the same conditions, the cold air works to everyones advantage (though in some turbo'd cars the timing can get a bit too advanced and cause the knock sensor to step in). alsol honda motors are very very suceptible to changes in air temp, it's likely that the colder air is more to his benefit than ours.

 

plus ITR and FC dont weigh the same....

just the same reason a 500hp rx7 can run 10s, and a 1000hp supra runs 10s

 

wrong the supra runs 12's

 

hehe, I've seen 700hp supras run 13s but my favorite is seeing 3000GTs try out running RX7s (FDs). For me that's fun to watch.

 

there are pros and cons to every comparison...try getting 700-1000 hp out of an FD with unmodded internals and everyday driveability, I'd take a 3000GT or Supra over an FD for a killer street/drag car any day!! I'd likely choose the 3000GT (AWD means slap on some actual snow tires on stock rims and voila, instant all season street machine). The 3000GT has it's own problems too, ever work in that engine bay?? It's more cramped than a 300ZXTT

 

-40c, isnt that about -40*f, wtf were you doin out in that kinda weather.

 

-40C is like -104F. I live in oakville, i dont recall -104F temperatures. Of course i didnt go outside, and it was like -25 when i was working on my car in the parking lot at sheridan.

 

Actually -40C EQUALS -40F

Yea prolly -40F lol...-40C is wayyyyyyyyyyyyy to ******* cold

 

this is about as logical as 100lbs=1/10th in the quarter

 

f=c*1.8+32

f=(-40C)*1.8+32

Therefore

-40C=-40F

 

Eh, I'd rather a camaro :p

 

Cold air intakes, composite intake manifolds, intercoolers . . etc. all harness the power of greater concentration of O2 in cooler air.

There is this crazy idea I have . . O2 is paramagnetic . . it can be actually separated from the N2 and other gasses in normal air with strong magnet. Some day I am going to experiment with a _strong_ electromagnetic screen in the intake system which will be switched on and off at the right tempo to match the pulsing intake flow. I just haven't figured out how to purge the N2 and other stuff after the magnet separates the O2.

But just imagine: more boost than turbo with no PSI, no heated intake charge, no compressors or funky vacuum and oil line networks . .

 

Large electro-magnets need a LOT power from somewhere . . . . and are quite heavy . . . and are capable of generating lots of heat . . . Do you think that you can make the power worthwhile above that ?

You'd need to think of some way to use that to encourage more O2 from the outside air to come in, it wouldnt be useful to simply 'pulse' the intake charge already present in the intake tract.

Purging everything else would involve blowing it off or making it travel down another path . . . and that would probably interfere with the pulse to begin with.

Perhaps an air storage system, much like the one present on chevy's VORTEC would profit more from such a design.

Though I still have doubts of such a system being able to work well, and even be remotely worth the cost and power use, I dont want to get you down, as many many MANY great designes were totally doubted and ridiculed before they came out

Good luck!

 

Brainstorming usually comes up with many, many wild ideas which each hatch concepts that combine to produce an offspring of more feasible proposals, finally copulating to bear the final, workable solution that lands quite outside "the box".
