Air Intake.

[arronm]

A cut up airbox just sucks hot air from the engine bay.

Above video. They sound the same to me. Cant hear the spool.

I hole-sawed a 4'' hole on the bottom front of mine,aside from any air flow improvement (k'n filter also installed) its virtually impossible to know its there

NVT (Dan) thanks mate great info.

I've already spoken with Kev about lining me up with cooler, air intake and muffler delete but will need to wait a month as all out of coolers ATM. Can the air intake and muffler delete be fitted before tune? or should I just wait.

Im not after anything to loud its still a family car and a lux car too but will give it a go.

As good as it looks and tidy I was thinking being so low down and right next to the engine all youre doing to getting hot air straight from engine.

nah that's to much work biz.

Maybe KPM can do me a deal with Air box and ID1000

The Streetfighter Airbox recieves cool dense Air from over headlight and grill directly. There is no under bonnet hot air at all.

Coupled with the Massive 5 inch BMC Twin Air Filter it recives the largest delivery of any airbox on the market.

Would be happy to negate price of freight for the Streetfighter Airbox as well as the KPM1000cc Injectors.

I will also throw in the Race cover.

Both direct fit

For non-turbo side intake I reckon KPM is the goods.

there is an increase in turbo noise but not enough to pick up in a video and not significant enough to justify buying the intake. You probably need to swap out the silencer pipe if you want to hear the turbo spinning up constantly. The big noise difference is from the recirc valve, it's much, much louder than it was before. I had a K&N pod filter setup on my old XR5 and the constant turbo hissing got on my nerves, I just want the flutter when I lift off to shift.

Oh noooo now the table has turned..........

Man that looks good KPM. If an air intake looks sexy that the one.

TURBO SIDE! TURBO SIDE!

[Joorsh]

Regarding sucking in hot air, the standard airbox is on the cold side of the motor, so temps are quite tame in that area. I'd say that's probably why Mr Ford has the intake pipe crossing over like it does in the first place.

As soon as you're doing more than 10kmph, cold air absolutely belts in around the airbox from the side of the radiator support panel and headlight surround. You're going to see virtually no intake difference.

Further more, when it hits the turbo it'll be heated up massively, so even if there are a few degrees difference at the intake those differences will be negligible after is passes through (or very close to) the red-hot sections of a glowing turbo.

Your intercooler is going to do all the work cooling it off afterwards. Yes there are turbo thermal efficiency gains to be had from slightly cooler intake temps pre-compression, but I honestly don't think we'd be talking more than 2-3 degrees difference here. When people talk about how much better their car performs on a cold day, that's largely due to the intercooler performing better, rather than the initial pre-turbo intake temps. They still play a part, but not nearly as much as the intercooler does.

The other thing worth mentioning here is that I have actual, quantifiable performance gains from my intake mods. So regardless of any discussion, the evidence shows that it does work. I'm not sure what the real-world gains are from those aftermarket intakes, but I would assume (hope!) they would be slightly better than my approach. How much better than mine, I don't know. If anyone has any pre/post dyno figures I'd be very interested to see them. Just beware that manufacturers will often claim figures like "+45kw", but it will be on a car already making 300rwkw. To be fair in comparison we'd need to see it on a dead stock car like mine. The gains from intake and exhaust mods increase exponentially as you modify engines (in particular, increased gas velocity and volume).

Regarding the sound, yeah there's a bit more induction noise with my mods - a very soft whistling sound. You don't really hear it in the cabin though. It's certainly not offensive, and nothing the boys in blue are going to even glance at. It's much, MUCH quieter than the Nissan RB & SR engines. It's even quieter than the Toyota 1J & 2J series, and those are pretty tame standard.

As for looks, most of those aftermarket intakes look pretty damn good - there's definitely no competing with that. That KPM one in particular looks very nice, and there's no question that it would flow really well.

Well said, it was exactly what I was thinking. By the time it hits the turbo, heats up again then thru the intercooler, it would be very minimal difference.

Also, where is the Cold Air feed for the drivers side air box? I dont think I have ever seen one so I assume all of the air is coming from the engine bay just like your modded xr6 box.
