Default Inlet hose, Spool faster or not?

In preparation for my new motor (next summer lol) I am going to do EVERYTHING in my powe to optomize spoolup
I started porting exh manifolds for my car today, I have already ported the P20 on my VF22 (with MUCH success), I plan on header wrapping the manifolds and up pipe (as well the crosspipe) and downpipe.
I have read nothing but good about the install of the perrin inlet hose. The entire reason I havent done one already, was being a puss about the install.
With teh perrin, that reason is gone.

But will it help spool? Even a 200rpm sooner spoolup is WAY worth it to me for the 249 bucks...
Will it happen? Is it snake oil?

IMHO I think thats a very over rated and expensive mod for the performance output it gives. I ran my VF22 setup for a while with the stock inlet hose @20psi on 94 oct and had no issues.....tried the perring inlet hose that a buddy had....didnt do much breathed a bit better, but thats about it.....I would do that mod when you have a bigger turbo that moves lots of air....then you would probally gain more bang for your buck!

I say if you have the extra money go for it. Personally, I would love to have one of the AVO/BPM/MRT L shaped ones that replace all that crap, but $400 is way too rich for my blood. You might consider wrapping your turbo in Thermo Tec wrap as well. It will destroy a lot of heat soak issues and keep your turbo nice and hot. This might help spool a touch too, but I wrapped mine in conjunction with a P&P, I wasn't able to tell how much/if at all it helped.

I think that the inlet is an important mod, to be done along the way sometime, if you are going to mod to the point of going to a bigger turbo....OR....you want to squeeze the last bit out of the TD04.
For a bigger turbo, the AVO/BPM/MRT inlet would be the better choice, and if I end up doing anything other than the EJ20, that's what will be on mine.....the Samco or Perrin would suffice for an app using the TD04.

The biggest benifit that I saw was transient throttle response, and with a P&P turbo and P&P TB, I think that it would be well worth it, indeed.

How much was it to coat the factory heat shield Dave? And it's only the top half, correct?

I did notice noticeable improvement in performance after the inlet hose installed. On my car, the stock hose was leaking and drive the ECU crazy. I think it is a worthy mod.
