Default APS inlet pipe/K&N Typhoon - how to make it fit

Went to have the APS inlet pipe installed today...before the manifold came off tried to fit the supplied connection hose to the K&N Typhoon...but it's too big for the Typhoon!!! So I will either be selling the APS inlet or buying a APS Cai if APS doesnt have a solution for me

Just tighten the clamp down. The ID if the boot is 3". My Perrin big MAF is 2.75" It tightened down just fine. Or you could get a transition boot. Both easy solutions.

I'm using the APS inlet with the stock airbox. Just tighten that clamp down.

...? We all take chances with creep on the VF39, assuming that is what he is running.

The inlet probably won't cause creep. Creep usually comes when changing to a higher flowing DP. And mostly catless DP's

With a stock intake and stock inlet pipe, there is enough pressure drop before the compressor so that the turbo actually has to work at a higher pressure ratio (higher turbine speed) to make a given amount of boost in the intake manifold. If you reduce that intake restriction to negligible levels via a really high flowing intake and, say, an APS Inlet Pipe, the turbo no longer needs to spin as fast as it did before to produce the same amount of boost. This means that if previously your setup was close to the edge of having creep, an intake and/or inlet pipe could push the system into a creeping state. I have frequently seen boost levels rise when installing intakes and the like and it is definitely more common to see creep on cars with intake & exhaust than with just the exhaust.

If that's the case then the outside diameter of the typhoon must be smaller than the stock air box connection - makes no sense to me, why go smaller on the OD than stock?

Can the title of this thread be changed?
It's totally misleading.
Thanks

Thanks for that info, all makes sense now.

nhluhr, great explaination. I never realized you would raise the chance of creep with less restrictive intake pieces...good to know. Nice tip on using the supplied K&N silicone adapter. Thanks, all is clear now
