Forge Valve install/impressions

The point is for one revolution out of 60 the engine is getting slightly hotter air. It is only hotter due to heating by the wheel and some efficiency factor and I bet most of this heat is dissipated in the intercooler. Most of the temperature increase is lost due to the reduction in pressure as it is vented back into the intake. In fact, with an awesome intercooler, the air expanding out of the valve could be COLDER than ambient. Its how every refrigeration (save thermo-electric)system works.

Even if there is a minimal increase in temperature were to have an effect on the engine it would most likley only affect 1 revolution of the engine which when running at 4000RPM is only 15 milliseconds.

Thus the whole BOV>BPV arguement is based on a very slight performance decrease for 15 milliseconds, which is probably occurs before you even manage to get the throttle to the floor.

so to sum up your point. your point is that hot air doesn't effect power

I guarantee you're still running rich when you're back in gear and on the gas. it's gotta take longer than just the shift to get the air and fuel right again.

no, his point is the same as mine. even if the air is hotter, it's only effecting power for an extremely short period of time. probably not even noticeable.

hey guys, why not try it. I wouldn't recommend keeping it that way permenantly cuase youll evenuttly fart your cats out the tail pipe. My good freind Jordan at Cp-e is making a map to fix that issue for me, but try it for a few hours the put it back th recur. then come back and give your opinions..

i know im running rich thats why i took it off till Jordan finishes my vta map for the standback

 

[sleeper3]

I'd rather not run rich at all. call me crazy, but I'm going to stick with the orientation the engineers at mazda thought was best...

and doesn't running rich decrease your power? hmmmmmm...

samesies. I feel like deleting this thread.

 

[Powerslave]

your only running rich between shift iv'e already said that 10 times... also the only reason mazda ran recuric is cuase its more civilized improves drivability and good for the turbo, but not for power...

 

[Powerslave]

you wuss!!..lol

 

[sleeper3]

i'm running vta and can really tell a diff in power cuase its all cold air, there seems to be a tad mnore lag down low but when it comes it comes sharp and HARD cuaseing wiplash

this is making me laugh now. cause before you said it lags down low, and now you are saying the hot air makes recirc lag down low.

 

[sleeper3]

lol this thread is full of annoying.

 

[Powerslave]

it does lag down low more sorry if that makes you luagh... but on boost its much better hahahaha. When did I say recuric makes it lag down low???

 

[Powerslave]

i never said recuric makes it lag down low... why did you say that?

 

[sleeper3]

you've now completely confirmed that VTA is a worse solution. the elimination of the "hot air" obviously has no effect at all, as it would only effect you "down low" and you are even more obviously only holding more boost with the new valve, as you just said the boost is much better.

I am glad to know the truth now. I can unsubscribe from this thread now.

 

[sleeper3]

i never said recuric makes it lag down low... why did you say that?

you're saying the hot air makes us lag. the hot air is gone within milliseconds of a shift, or "down low"

 

[speed3shon]

i know how it works and i know about the running rich part i'm taking care of that, you physics are backwards!! yes hotter air requires higher octane to prevent detonation cuase there is not enough oxygen. Your awnser is FLAWED AND DOENSNT MAKE ANY SENSE! your saying venting off hot air will make the engine produce hot air???(braindead If the intake temp is colder you have more oxygen, better combustion and more power. thats it, on boost vta is delivering the SAME amount of air as recur and it much colder than haveing a shot of 200 degree air. if your going to respond atleast say something that sounds halfway intelligent....

no, i didnt say that venting hot air had anything to do with it making hot air.

the turbo heats air. ok, vent some of that off.. its gonna keep heating intake air.

the vented air is hot because it went through the turbo... so, all air that goes through it WILL ALSO BE HOT.

you just repeated everything i said about colder air having more oxygen you twat.

can you read? higher octane gas burns slower... its more stable. thats why hotter intake air requires higher octane, not because theres any less oxygen.

hotter air with fuel will combust easier. detonation. hot air with higher octane fuel will not detonate as easily because the gas burns slower and is more stable.

havent you accepted the fact that its not 200* air yet? your talking about a SMALL volume of air... a small volume of air that is going to be mixed with cooler air, heated up again, and then pass through an intercooler...

you can say all you want about my physics being wrong. but your the one thats off on this one.

you saying im wrong doesnt mean i am wrong and you are right. in this case it means you just dont grasp the concept.

ok according to you "ive completely confirmed that the car is unaffected by extremely hot air, man if this car was on the sun at would run4 second quarter's..lol

is english not your first language? I'm not trying to be mean. you're just not understanding what I am saying.
