POP Chargers(???) vs. the OEM SET UP ...who wins, you decide

[Zzzz...]

After reading about the pochargers i was going to add a comment but it would have taken it off topic so im post it separately

 

Anyway... I have been looking at these forums about popcharger thingies

 

but I honestly cannot see the point of them...unless it is just for noise and ASW'ing

 

even with those heat shields they are more of a "warm air intake" than anything else!

 

I know you get a direct airflow from the front, but this is the same as before in the encased box filter.

 

the cone then sucks air from the around and sides and I think it is more likely to suck air from the engine side... even with the heat shield so the air temperatures are going to be a bit higher...

 

The big plastic box I think is more likely to prevent warm air into the system and the air come directly from the front, hits the filter and goes through...

SO I think getting a high flow panel filter would be better in this case... and perhaps thermally insulate the box

 

I imagine noise-wise it is better but performance wise it makes little or worse difference... Has anyone got actual data showing improvements in performance ?

PLease convince me...or sell it to me...

 

debate please ... if you show me good data (independant data) i might consider investing in one... but the science has to be proven...

 

 

basically my stance is that I think the original set up is a good as these popchargers... thingies for performance...

and that OEM with a high flow filter will be better than a pop charger

for performance... (I am not so bothered about the noise...)

I bought mine primarily for the noise , then the looks, then because I had a mad desire to blow some cash extra HP never came into the equation

agree! from a looks point of view it looks better and from noise point of view also probably much better... and that heat shiled you got seems a lot more elaborate...maybe better at shielding from engine bay temp.

All the induction manufactures claim to have dyno results showing gains.

Independant rolling road days show little if any difference.

Main gains, looks and sound, end of.

Thank you! that's what i thought...

I just hope no one has any ideas that these things help engine performance... and pay money for that purpose..

Don't get me wrong you can make them work to some advantage but need to fully enclose and direct feed to get the real gains, 350Z ECU cancels any gains anyway so piggyback or stand alone ECU required to get the advantage.

No noticable difference with my JWT popcharger, other than poorer fuel consumption which i think is something to do with me planting my right foot at every opportunity to hear that induction noise

 

Worth every penny IMHO

A lot of Jap tunning houses zeds all use std enclosed boxes with chromed intake tubes. Big open air filters give good gains in turbo cars mainly. Better to increase air flow/re-direct air flow to std air intake. IMO heatsoak may cause marginal power losses with pop chargers.

i red on some webdsite that the pop chargers give 1 more hp than the nismo full air intake system i think it was on a site supplying nismo accessories.

 

it sed the nismo 5.5hp

and 6.5hp

[GC350z]

IMO they suck. Sound great but suck. Most can even reduce performance because they are not taking in clean air as they are not encased. As stated above the Z ecu does adapt and cancels out any potential gains.

 

Mate of mine has a Skyline 34. It arrived in the country with a charger installed. I got him to source an original air box. Power increase, drive was smoother, oil consumption returned to normal. Happy camper.

They do suck, that's their job..... sorry....

 

I have one for noise alnoe. I think it sounds cool. Never considered benefits of any mod to be honest. If I want it I'll buy it for whatever reason I decide. I don't get scientific about it. If I did my car would probably be absolutely stock.

[Zzzz...]

I am just thinking on performance side alone...

 

The nismo exhaust i can imagine allows gas to flow quicker out of the engine... ok which then allows more clean air and fuel in... etc...

 

so if I was to go the nismo exhaust route, I would want to guarantee the best airflow in... and at the moment I can only say that i think the box with perhaps a better panel filter will be the better set up... then of course the kinetix plenum to increase and distribute better the airflow to all cylinders... it would make the efficiencies better thoughout, but as you all mention, limited performance up due to the ECU setup...

[Stew]

Well what do Nismo use on their own S1 and S2 engines?

 

I'd imagine that would be the best route I'd have thought!

[Sarnie]

I think that not only is this one of the cheapest mods to do, its also one of the best. If you don't have £800 for a Nismo exhaust then £85 on one of this is a steal

[GC350z]

Or if your car is a MY07 get 2

[N15MNO-Daron]

Got my K&N Typhoon kit on its way from States.. it got fully enclosed heat shield box.. so shudnt have any heat problems.. and Nismo exhuast fitted already.. sound from these shud be awsome.. now just need that re-map from TDI to get more power

[Chris`I]

I'm probably going to get a BMC CDA. Its a conical (sp?) filter housed in a carbon box. Meant to work really well, used loads on Alfas and VAG cars. Not to mention they make the filters for Ferarri (both road and F1!) - good enough for me then! Not used much in Zeds, but see if I can start a trend

 

[M350ZB]

Chris where did you get your filter from, and what the cost compared to a JWT pop-charger ?
