The last thing I would ever do to my engine would be to fit an induction kit!
A complete waste of money, and alone (or even with most mods) will do nothing for the performace of your engine what so ever. Apart from kill the bottom end and mid range.
Standard airfilters and airboxes flow more than enough air for any modifications to your engine bar fitting a turbo.
Now go get a re-map with a stock air filter and see how much difference your induction kit makes!
They are a waste of money. They offer no performace increase on their own. Standard air filters are more than capable of flowing alot of air.
It's only the manufactures and re-sellers that claim they actually work, and thats because they sell them.
I've worked on alot of turbo engines, aftermarket filters offered no inprovement alone over stock ones. I've seen the dyno graphs to prove it.
A large airbox with still, cold dence air is what you need to aim for.
If you are happy to pay out for induction kits when you get a re-map, then go for it. You dont need to!
Now go get a re-map with a stock air filter and see how much difference your induction kit makes!
:bang::nutter:
(this was pre-remap BTW)
I've never messed around with induction, so can't speak from experience, but must admit I had my JTD flying at a speed I really don't want to mention (let's just say I was passing an Abarth at the time :slayer
Apart from thoughts of "What the hell am I doing this speed for!" it also struck me that there couldn't be much wrong with the standard induction
Not sure how the airflow measures around the bonnet area but I'd imagine there's quite a ram effect :chin:
That's true Red but just wondered if air-flow (at speed) may not be accounted for when on the RR.but as you know td's and n/a perform massivly differntly
but what about outright top speed (or shouldn't I ask )so your saying a remap on its own adds 39+ bhp to my car
And your saying a filter alone adds almost 30bhp?
171 after remap and then 199 with the filter?
just shut the hell up and ask everybody on this forum with a GSR kit.
i have my graphs to prove this so?! how else would the extra bhp be on my car???
fairy dust perhaps??? some bloody strong fairy dust then
Agro - it did 150 at the ring, and the speedo is 5mph out
iv had enough of people not taking in the facts, just read the forum, or is that too hard too?
Look, I'm not saying this just to **** you off, or to wind you up. I'm simply saying, I know, for a fact, that you will not gain 30bhp from an air filter.
Simple as that.
I've worked on cars & bikes, built and tuned engines for the past 15 years. I done alot of work on my old twin turbo Supra with regards to airflow into the engine. And even with it fitted with a pair of rather large hybrid turbo's (RS500 spec), the stock box and filter were still easily capable of flowing enough air to the engine. I experimented with a few different setups and none gave any improvements over standard, all work was done on a dyno.
Car manufactures spend millions on engine development. Do you really think they would chuck an airbox and filter on that was running at its full potential with regards to the engine?
The ONLY time I would ever think of replacing the airbox or filter is if I was going racing. You just have to look under the bonnet of a BTCC car and see they all use an enclosed airbox, as do pretty much all race cars. Simply because you get better power.
Cold, still, dence air. That it what you want to aim for. A cone filter sitting on the end of a bit of silicone pipe is not going to give you this, and therefore give you no power advantage.
I think Greggers was just saying it's good to keep disagreements civil rather then degrading to name calling :shakehead:what you getting at greg
