What is the best induction kit I should go for?

[onapper]

I have a mk1 Cupra r and currently I have only a viper cross panel filter on there. I wanting to gain a better sound without losing a few horses (bhp). Just wanting people's advice about what I should get. I have seen an induction kit on the jabba website it's an enclosed one.. Well when I say enclosed.. It has it's own closed off area behind the battery. It costs £235. And can give me 4-6bhp,so it states.

when you say viper cross panel.

are you getting mixed up? have you got a pipercross panel filter or the pipercross enclosed induction kit? they are both completely different

The panel filter that goes in the standard airbox.

I gained 4bhp from a large Jetex cone filter, but also added a cold air feed pipe.

The thing is about just a cone filter is that it will suck
In the warn
Air from the engine bay. We have a standard airfeed anyway. Where abouts did you place your airfeed?

 

[cupra_mike]

so youve got a pipercross panel... most go for jetex filter with a heat shield to prevent sucking hot air from engine. you could also smooth your air box and keep your panel

 

[onapper]

Yeah lol I dont know why I was putting viper hahaha. I would also get a good sound from an induction kit.

 

[cupra_mike]

if you smooth air box, drill bottom with your pipercross panel you will get performance and a nice sound

If you want a real performance gain, badger 5 tip, jetex cone filter with a heat shield. This will gain you 10+ bhp and lots of noise. I gained 15 bhp from having this set up but it isnt cheap. Your looking at £250 but it is worth it and a must if you go hybrid.

The Jabba one is pretty enclosed... you can hear the vacuum sucking against the bonnet.

But dont forget the turbo super heats the air anyway , its the intercoolers job to control that. Keeping dirty air away will prolong the filter so enclosed is no bad thing

Keeping the air inlet temps cool reaps benefits and is important, even if it only reduces the temp at the tb by 1 degree.

 

[sambryant]

Induction kit for air flow (gs)
Intercooler for lower intake temps.

 

[Mark300zx]

It always raises a lot of discussion but IMHO keeping the air temp down at the filter is very important as it has a knock on effect for performance and reliability.

 

[sambryant]

Not true really. When the air leaves the turbo at 300 degress its the cooler that brings these temps down. I have no cold feed to my filter and i was logging the other week. Intake temps we 19 degrees at idle, when booting it at 6.5k my intake temps were 29. This shows my cooler is doing a great job and cant see how a cold feed will help in any way. Also when the car is moving the air that hits the bay will be cooler as its moving, works like a fan. Cold feed for na cars but makes no real difference on turbo.

So why did VW, Seat, Skoda all fit them as standard to non modified production cars, they certainly missed an opportunity to make few more quid by not fitting these extra parts!

 

[Henjo24]

I connected my cold air from the top grill next to the seat badge and tied it onto the Jetex cone. im happy with it aslong as ive gained some BHP.

this is because it and inclosed box. like all inclosed induction kits have a air feed pipes. on the standard box they use the feed pipe as air feed to the box as gs would be too low.

so please tell me what would i gain if my intake temps were 1 degree less so lets say 18, its still going to exit the turbo at 300. like i said its all down to the intercooler.

 

[Mark300zx]

Here you go, have a look at section 7

http://www.gnttype.org/techarea/turbo/intercooler.html

 

[sambryant]

there talking about big difference in intake temps 16 degress. a cold feed will only be 1 or 2 at the most. they say 16 will make it 10 degrees at the cooler. so 1or 2 degrees at the the turbo = less then 1 degree at the cooler no power gain.
anyway that info is not any use to this matter as they are using cooler temps by turning boost down, were still running the same boost so temps wont come down.

 

[onapper]

Seems like a full on debate on here haha, so what do you think I should go for keep the standard air box or go all out and spend 250 on that induction kit that sam was on about.
