Jap Race pod filters
Hey does anyone know if those coloured pod filters from Jap Race supplies are any good?, or should i just save up some more and get a K&N pod or better still just keep my K&N panel.

Re: Jap Race pod filters
Keep your panel and duct some cold air directly to it I'd say.

There was a thread a while back about AE101 owners taking their pods OFF and beleiving the cars ran
BETTER. So there you go :)

Re: Jap Race pod filters
ive got a k&n panel in at the moment, i also have a k&n pod, i switch between them all the time (developemnet perposes) and the pod is defenatly alot more freeflowing! (u can hear the quad throttle boddies in the hi rev range w/ the pod)

Re: Jap Race pod filters
Your kidding yourself,pulling air from the bay depletes power,the average under bonnet temp is around 80degc,ambiant especially where you are,would struggle past 15c.As you can see,theres a vast difference,besides,a pod
only allows a lower volume of air to be inducted,I would suggest the noise you are hearing is simply the resonation inside the plenum,caused by less volume,dont you think the factory would have saved money designing airboxes,if that worked?

Re: Jap Race pod filters
most factory airboxes are made to reduce noise
compromising on airflow to do this
so it depends how crap your factory box is on how much the
gain will be, personally my original piping ran across the top
of the radiator, so i would get a greater imporovement than a
well designed factory airbox.
when doing a pod you should also isolate it from the engine
bay heat , and duct air fromt the front to it

Re: Jap Race pod filters
Well my plan was to get the pod and then put in some hood vents over it to let more air into it so if i kept the panel would puting the vents still help or would it just be rice?

Rice!...c'mon,think,air is "ambiant" "ambiance" is French for "surroundings" air is everywhere,so is moisture,moisture in air acts as a conductor,I laugh when I see guys surrounding there air filter with polished alloy..alloy conducts..heres a simple tip for cold air induction "GET OUTSIDE THE ENGINE BAY"!

Re: Jap Race pod filters
I agree with nzrwdstrlt :) ..also, its probably not a good idea making holes above your pod filter unless you like rain in your engine.

smuggla thinks he knows everything about everything i dont care about some crap that just one guy comes up with because hes read two or three more books than someone else so unless youve actually written a book or are a famous well known tuner just go with the flow instead of trying to get people to agree with youre stuff all the time im a great toyota fan but feel that the new engines just dont cut it compared to other companies the only good engines with reasonable power start with the turbo mr2 engine and up from their .
just some lite critiscm hope you can handle for once lads but most of it is the truth .
just remember good old faithful toyota build a nice long living package but compromise this for power

pods....
when the car is moving theres going to be f all
heat soak anyway cos air is being pushed through
the engine bay, and alloy surrounding the pod will
have an effect, alloy doesnt retain heat like stainless
so when the air flow from outside builds up it will
quickly dissipate its soaked heat.

Re: pods....
thats an assumption nzrwdstrlt.

it would be very unlikely the temp inside the engine bay will be the same as out side it. but sure the faster you go the cooler the engine bay temp.However the difference on a N/A car might be little.

humm this is an assumption too.

This is another one of those things someone needs to test and prove.

Re: pods....
Lorolla,I dont know what your on about,I havent read any books...some magazine articles,but,not too many books on modding multivalves,besides,the info I gave above is generic,it's the same for any engine,all that I speak of is from hands on experience,if you dont like what I have to say,just ignore my posts,no1 is putting a gun to your head.

Cobra,vents are fine,they help release hot air from the bay,still,there of no relavence to the induction.

Re: pods....
If you want cold air then run the filter to behind the front bumper, you will get maximum cool air there and you wont get as much heat soak from the engine bay as you would in it. It will require more piping and possibly cutting a hole but its the coolest place, unless you wanna run it under the front wheel guard. Think of it like an intercooler, you wouldnt want to place one in the engine bay for the fact the heat absorbsion is much higher so the cooling ability of the unit decreases due to inefficiency. So you want to keep it away from the heat source as much as possible. There is lots of ways to do this, this is just my opinion. Smuggla's ideas are correct and alloy does transfer and hold heat and polished alloy is even worse, this makes it more heat absorbant and heat reflectant. If you really still wanna put it in the engine bay, make a little box for it, using per say heat resistant panels. And run some air conditioning ducting from under the car upto the filter.

Re: Jap Race pod filters
Yeah, the ducting etc for your factory airbox should come into your decission, mine was quite good (piped from front guard), so thats why I'm sticking with it.

As for vents, I don't think a couple of plastic vents "jimmied" onto your bonnet is going to do a whole heap, as others have mentioned there is quite a science to getting these to work, you really need a wind tunnel or some way to test the location of the vent on your car to make sure it would actually DO anything positive, rather than just distrupt the airflow over the bonnet surface. I'd go so far to say that the cheap types of plastic venting you can buy would do little or nothing if placed directly over a pod..... of course, when stopped, or at lower speeds, it helps to stop heat soak in the bay..... no disputing that. Oh yeah, i think they'd look phat rather than too ricey on the older fxgts, but thats just me ;)

Finally, I'm skeptical about how much cool air is actually "forced" through the engine bays at speed.....not enough, I would say, to counter the heat soak most are experiencing. With the AC / Radiator etc tightly packed in and underneight plastic plates [well, on my car anyway], I don't see a decent volume of air getting forced in?

vents
ive always been informed that a rearwards
facing vent or scoop has a better effect, like putting
vents on the boonet just behind the radiator facing
backwards will create a flow from the throuhg the grill
and out the top. you need to make a path for air to
enter put also to exit.

you could just cut a hole in the bonnet and sit the pod outside :) , but then youll face problems with a turbulent airflow...

cold air
go the cold air induction, its heaps better. Just run some pipe from the air box down into the place where the resonator used to be ( if you have taken it out already) and down facing out the front grill, easy man.

lorolla: What makes you say that?

Yeah I think a rearward facing scoop to let hot air out of the bonnet and keep and good flow of cool air coming in would be much better. Or you could raise your bonnet about 1" at the back like the Pulsar in this months PC.

yo dude you cant even begin to realise how much you would have to do to youre 20 valve to actually make it a real fast car how much power do you guys get from youre mods theres a guy here in whangarei who has done a few mods to his integra vtec 1600 and is running a 13.8 now when you guys can show me a levin running that time then ill beleive that they actually are a good motor the motor was origionally designed for fuel economy not high performance and whenever someone asks whos the fastest in toyspeed itys the guy with the twelve second mr2 which seems to be everyones answerjust thought id give you some insite to my views of this paticular engine

Re: freezeup
Yep,your on the money lorolla,the 20V is a joke,especially the blacktop,I'm so glad I have never come across 1,I mean,I used to have a 100K/W engine and it used to really annoy me the way those Hondas toyed with me,allways hanging around behind me like a missguided faggot,all you have to do is look at the utterly MASSIVE plenums on a Honda and you can see why there a real competitor,I'm not sure if its he HUGE C/R
9.5:1 that gives them there awesome performance,or the pissweak blocks??? Does "the guy" with the 13.8 Honda know?
He must,he must be running 1 of them wild air cleaner things,or,nooo being a Honda,he may well be running "Carbon Fibre" stickers...yep,there good for 10K/W's at idle,or maybe he's running a 322 degree cam with 12mm lift...oh..no hang on,he cant,thats only for those gimps at TRD,there tossers too,I mean,Mugen comes up with real rad tech,they push the envelope,all us Toyota guys know Honda is the king,but can you do us pussies a favour?? please dont tell any1,I really appreciate that. *Phew*,I was worried that MUGEN might just have a special 1 off engine they gave to "the guy" to teach us wassup,can you tell me 1 more thing...what are the gear ratio's on "the guys" 6 shifter,I mean,Honda are so up with it that there all running 6speeds,yep,were a backward lot us Toyota guys,but hey,do 1 thing B4 you respond,get "the timecard" off of "the guy" and scan it,post it and we will all pay homage,because the day you show me a Honda 1.6 that cuts a 13.8,I'll buy the fucker.

not saying toyotas are crap and not saying hondas
are cool (personally i dont like them but that has more to do with dickhead driver attitudes) but you do have to
admit there are some damn fast N/A hondas out there-
curently a b18 powered civic running 13.5 with minimal mods, and i have yet to see N/A toyotas running those sorts of times (though i really would like to)

"yo dude you cant even begin to realise how much you would have to do to youre 20 valve to actually make it a real fast car"
I can't? besides, I don't have a 20v.

"theres a guy here in whangarei who has done a few mods to his integra vtec 1600 and is running a 13.8"
Thats nice, does that mean 4A-GEs are no good?

"the motor was origionally designed for fuel economy not high performance"
The GE head is designed for performance, the FE head is a fuel economy head. A 4A-GE is a performance engine.

"whenever someone asks whos the fastest in toyspeed itys the guy with the twelve second mr2"
Where you expecting a 4A-GE powered Levin to be getting 12s instead? ...I'm sure those honda drivers have some b16 n/as in the 12s?

Re: civics
I don’t think it is a fear contest . I mean the 1600 Vtec has been rolling around in NZ since the late 80’s Where as the only descent 20v came in the AE101 of early 90’s but because this engine was only brought into the country in the last 2 years really, and has only gained in popularity in the last year . I don’t think this is enough time for anyone in NZ to develop the engine to the same level as the Honda engine. I believe with time and development it will as fast or faster than the Vtec… We just need time to develop it. Us Toyota boys are doing it for ourselves we don’t have big tuning companies behind us like M’s racing and Advanced imports blah blah …. So the power we get from our engines is due to the time WE put into researching and testing with the engine. We can’t simply walk into a shop in NZ and pick up a set of extractors that have been developed over 10+ years and have had lots of research money spent on them . Toyotas are not brainless cars to get power from, you have to think not just pay of parts hanging on the wall



yeah I have seen Honda N/A’s in the 13’s …..So you might have to sell that blacktop … hehhe gotta love Toyota’s though

Re: Jap Race pod filters
Ultrasonic makes an excellent point, Toyota, so far, just doesn't have the aftermarket support to make their engines really fly.....

Honda makes good cars...... most, if not all of their 90s NA engines are more powerful than the Toyota equivilents. That is an EXCELLENT achievement. But the reason for most of their speed has to do with power to weight ratios..... This isn't really news to anyone, but is often missed when these types of discussions get "emmotional".

Im sure that any 13s honda is running stuff all interior, and on a very light car to start with, thats a brilliant combination. So, they are faster because they are so much lighter......no big science to it.

So, sure, they are fast , light cars? Theres nothing particularly special in that..... still its a good simple idea, that obviously works at the track. Would I own one? Hell no, I value my life :)

While I'm ranting, I don't care a toss if your car does 14 or 13s with the interior stripped out,
on AVGAS and 15psi in the drive wheels [for instance]. If you want to go that far, you may as
well just build a specialist drag car....? How many of these Honda owners drive the streets like
this? With tape over their door joints etc? I think not.
What matters to me is the performance you will see on the road, if you were to pull up at the
lights etc. If you run the same setup on your car at the strip, as you do on the road, now
thats impressive.... if not, the figures are a bit of a joke. Because as I've pointed out, almost
anyone can improve the power to weight ratio of their car with enough time and in turn, make
their car fly. However, its not practicle to actually drive like that, that is after all what a car is
intended for, isn't it? All you end up with, is some impressive numbers , that in the real world,
doesn't really mean squat.

Re: Jap Race pod filters
B16 vs 4A-GE...seems like a fair contest to me. The 4A has been here since 1984.. You can't just say there is a honda running 13s with natural aspiration, but I don't see any Corollas doing the same therefore they are crap. Or, toyota engines aren't as good because they are less powerfull from the factory than there honda equivalents...just means they are detuned more...

Get me one of those formula atlantic 4A-GEs and put it in a Corolla and lets see what its capable of...
I bet there will still be plenty of 1.6 integras with pod filters that could beat it cos they have vtek.

Re: Jap Race pod filters
Wo Wo Wo...where are these Hondas running 13's??? are you talking about Turbo mag? some other ricey US import mag?
No1 In OZ is running those times,not with an interior anywayz.
It doesnt take much to see that Carlsbad raceway in California
runs a 10deg decline.i.e,down hill.The hardest strip in the Southern Hemisphere,not to mention the planet is "Willowbank"
it runs a 4 deg incline and has long been regarded as the ICON
of drag racing across the planet.Basically,if you cut a record time at the "Willow",you got some serious bragging rights,I'm not into drag racing,but,I've never been beaten by a F/D Honda,so if theres a 13 running Honda in Sth east QLD,I'd love to run it,N/A ofcourse,as theres a low 12 rolla 20V haunting the Sth East presently,I'd go so far as to say that a 12.11=10.00 at Carlsbad in Cali. I'll put $500 on it as I have stated B4.Cheers.
