I've just undertaken this installation. It's a bit of a bear, access to this area is very, very tight on our cars.
Before you start, make sure you have everything. In particular verify that the new inlet has o-rings in the grooves on the turbo end of the pipe. Mine didn't have these, and I didn't realize these were missing until I had everything apart :-( . Removal of stock inlet pipe:
Installation is the reverse of removal, except that you leave off the nut on the turbo, there's no mounting tab on the Pure pipe. Gotchas:
Before and after: I have an EWG car, so I can't use PWM directly to gauge whether the turbo is working less hard, but PWM is on average lower than before. Trap speeds on my daily romp are the same or better. I noticed no more or less turbo noise than before (I have the PPK airbox). My Verdict: Low on bang for buck, but good for checking every mod box short of upgrading turbos. Good for peace of mind .

Great write up. Are the o rings Oem parts (# 2 gasket in the 1st post) or standard size items - if so what size did you use ? BP

Done and replied saying o rings en route. Fair play to Charles at Pure

Noticeable gains?
I feel it breathes much better, air + fuel make hp!

I never tried to hit 20 psi prior to fitting the inlet, I Didn't have sufficient octane at that point. I had the inlet on around a month and a half prior to fitting TBI. I don't have a before with this boost profile as mentioned above but looking at the data the turbo wouldn't of run these numbers further up the rpm range. Also the turbo didn't just run these numbers with the inlet fitted, I needed to do quite a few adjustments with the jb4 and its boost control using map 6. If you look on the previous page a member has posted my graphs from another forum which shows the difference at the same boost levels albeit lower. |

Update
Plot below is prior mods v latest intake mods with stock EWG turbo and Shell v power fuel ~ 98 RON Prior mods green lines from same dyno in 2015:- Map 6 Jb4 ewg board + harness and FF wires BCS sport cat DP MPE Oem air box with Afe dry drop in and afe airscoop Latest mods red lines recently:- As above but with intake mods as follows Map 6 - minor fettling co BW Chiptune. Dinan CAI with afe air scoop Wagner evo 2 comp FMIC ER boost pipes both sides of FMIC Pure hi flo inlet pipe Peak gains may look marginal but "area under the curve" is much improved. Deltas more evident from mid range upwards and Jason @ BW Chiptune drove the car after he'd fettled it and was v complimentary about how smooth the car felt. This is evident as red line is smoother than green line across the full rev range. I've yet to drive the car properly so too early to comment but what I've noticed initially is that Dinan CAI has more "voice" in a good way with Pure hi flo inlet pipe..... Hats off to the guys at BW - great service and advice as usual. BP

Update # 2
Avg ign on 98RON pump fuel was mid to high 2s before and now it's consistently less than 1 with same pump fuel. PWM is <40 so these 2 positive changes must be due to combo of new intake plumbing and BW map6 voodoo magic. Car was no slouch before, now it's stronger and intake sounds add more drama to the full bore experience !! Happy chappy

Probably a stupid question, what is the benefit from a lower PWM maintaining the same boost?

Turbo is being made to work less to achieve desired boost output.

1) From the comparison picture, only the aluminum section is actually smaller so it goes into stock pipe, though the opening that connects to compressor wheel is larger. Am I seeing it correct?
2) From the picture, it doesn't look to me like a solid piece, I am sure it feels different when handed on, but do you have concern on leakage? after all, it's two pieces preassembled. Quote:

I don't worry about leakage (your concern is unfiltered air, I guess). The 2 pieces are pretty securely clamped together.

And you're right, my concern is exactly if it's airtight enough to not let unfiltered air go into engine. By "securely clamped", did you mean it's just good enough?

This may be a dumb question, but is there any reason to go for Pure's pipes vs ER's pipes? The ER piping is all Aluminum, whereas the Pure ones seem to re-use part of the stock pipe (i.e. require cutting). Wouldn't it make more sense to go all-Aluminum when you're swapping the stock turbo for something more serious?
Regardless, both seem like a really nice upgrade even on the stock EWG turbo. Tempting... tempting.....

The Pure pipe has a lip and fits snugly into the stock plastic pipe. The clamp sits behind the lip. I feel confident that unfiltered air can't leak past the junction.
