I know there are a few people out there making the inlets, but what kind of HP numbers are we talking? Or is it just the turbo response that gets better? I might either do this or do a oil catch can setup before I get my car back on the road in a few months.

Any gains from this would probably be from the dyno giving different numbers every time.

The gains will be minimal but I think you are right in that the turbo spooling sooner is the bigger benefit here.

I keep reading 5hp/5-10tq from various places, but have not seen a single dyno...Kinda sad given at least 5 companies are making these. Have read one claim of "lots of area under the curve", mostly from the improved spooling I'd bet. For the price, 5/5 would be significant enough for me. Plus the added turbo noise folks are claiming...sweet.

the silicone inlets actually make your turbo quieter...contrary to belief

this one is from rpmc............
Before and after. The labels are from the dyno shop (Jet City Tuning).

I put a turbo inlet on after I installed a L2AIC and WOW! It was like adding 25mg of Ephedrine to the car. (Ephedrine is a brochilator...means makes you get more oxygen out of the air)

maybe on your car, my turbo sounds like a jet after my CP-E inlet install

ROFL! So funny.

Last night I was playing an online game and two guys were arguing about something. One of them calls the other a doch bag. The other responds smartly, "if you are going to insult me at least spell it right, it's doush bag!" I didn't have the heart to tell him that it is spelled douche bag....lol

Not sure why the turbo would spool sooner or you would gain much of anything from a TIP unless there was a restriction. The main benefit here is that the silicone will deal with heat better, dropping temps 1/2 degrees (keeping it at AAT/IAT longer). That and an aftermarket one will seal around the turbo better.. our stock POS comes loose very easily.

uh, there is a restriction. whats the point of replacing it if there was no restriction? the main benefit here is the faster spool and less restriction.

Test Results:

In house Dyno on a Dyno Dynamics dyno produced peak gains of 6.4 HP and 8.4 ft-lbs torque. Gains were across the RPM range and came on 200-300 RPMs earlier. Overall power under the curve is substantially increased.

That's right from the RPMC site ... problem is ... it's THEIR dyno that netted this ... since it is not a disinterested third party ... you have to nullify this ... however ... that being said I own a RPMC Turbo Inlet and do belive it is a great mod. I would say it's more of an acceleration mod than a HP / TQ mod ... for instance swapping out the stock wheels at 24 lbs with Mazda Speed Rays at 16.9 will yield you not horsepower but acceleration improvement (I have this combo on my car)... after installing and making my choice to go non silicone ... it's clear ... removing the restriction > all this "cooling" with silicone material... Great product (RPMC Turbo Inlet)... one of my best mods ... someone recently did suggest stomping your foot on the Mazda Speed 3 allows the boost to come on quick and also leave early ... slow and easy on the boost yields better results!!! I have found that since I can "hear" the turbo spool I can "ease on" the pedal ... slowing increasing boost levels and essentially getting "more" since I can better manage boost and performance ...

Next time I get my car on the dyno I'll pull the inlet pipe and do a comparison with the stock "pipe" (more of a snarled mess, but I guess it can be called a pipe). The TIP on my car is a prototype 2.5" hardpipe made in-house (production plans were cancelled, too many already on the market). It's similar to most other hardpipes.

I thought it made a rather noticeable improvement, seat of the pants. It made the car sound nicer too.

BTW... a turbo spooling earlier won't necessarily improve power under the curve. It will just allow the engine to produce power earlier and improve power on tip-in. It has no affect on power after the turbo is already producing the intended boost level.

A better turbo inlet pipe (one that flows better), will improve power under all conditions (even after the turbo is spooled up), because it improves the volumetric efficiency of the engine. Silicone or plastic inlet pipes do insulate a bit of heat, but the effect is minimal, there is very little surface area on the inside of that pipe and less heat transfers to the intake air than you would think. I experimented with a silicone intake pipe on a previous turbocharged project car and the measured IAT at idle was only different by about 3 or 4 degrees compared to an aluminum hardpipe, and even less difference was measured at highway speeds.

Contradiction. Earlier boost is by definition more power under the curve.
