We demand inlet for F series .!!! Darkhold I'm sure you asked them about it any time frame when it will be available for us ? :

Yes i asked. I guess by end of march, early april possibly.

Hutch tnx for sharing that log. I have pulls of running 14.5 psi tapering to 13 on 93 only. From 1st into 5th could make you a 2nd into 3rd monday. Pwm is higher in those gears. Why not test 4th gear? Pm me your email i send you few logs.

I have been away for a while and just getting caught up on this for spring.

Would I notice any real difference upgrading this inlet pipe on a stock turbo with a Dinan tune?

I am contemplating working with Pro Tuning Freaks and Cobb and possibly adding A Pure Turbo. I would prefer to not have to run any exotic fuel. I want to continue to run 91 or possibly upgrade to 93/94 if that makes sense.

Appreciate the input.

I think the stock inlets are designed to run with the stock turbo's. If you say you are running 91 octane you can't push boost up a lot. So if there are any gains I think they will be minimal.

The point of having upgraded inlets is that if you run more boost on stock or upgraded turbos that it's more easy on the hardware. Meaning the turbos can give the same boost at less dutycycle. This means in turn you could up the boost and increase duty cycle for more performance. So if not for performance you could do this for added reliability.

Pure Turbo stage 1 (and stage 2 I think) uses the stock turbo casing while upgrading the wheel. That is one of the beauties of Pure stage 1 - looks totally stock to the dealer - dealer would have take the turbo apart and measure the wheel to find the difference.

So if FBO running 93 w/E85 and/or meth, we are "maxing out" the turbos?

In that case the Pure Inlet would benefit us?

The first sentence is not true at all.

Piping the turbo and out are huge factors in power and Effieciencies!

More to come on exact number but I promise it's with the cost...

First sentence was a question!!! lol just trying to see if its worth it to run this without an upgraded turbo. Thanks for the reply, looking forward to seeing more results

Yes, the same housing but the housing has been bored out for a larger wheel and the inlet is larger diameter. That is why the pipe should be larger too. Gains on a stock turbo are probably nonexistent.

I might have to snag one of these soon too. Bi-yearly car cruise coming up in April and need to see how well I can keep up with the other guys

You may not gain much on stock turbo but you'd likely make it more happy per se and put it into a better efficiency range

[JETmn]

You wont' change the efficiency range of the turbo, but you may lower the pumping losses slightly. They may actually be increased though as now you are going to have a flat lip right before the compressor inlet. The stock pipe is the same size as the stock compressor inlet so you have a smooth flow. If you open the pipe up then the compressor will have a smaller inlet and cause turbulence right before the compressor inlet, which is the worst area for turbulence. I don't think I would try this on a stock turbo car.

You make an interesting point. Thanks for chiming in with your thoughts. Be curious to see data to this either way.

So depending how its sized if stage2 turbo is even more bored out at compressor side (which i guess it is) either this inlet is perfectly matched or you need one so you dont have a lip before compressor?

Maybe @pureturbos jesse can chime in. I guess its a valid question for him.

Yes, I am wondering how big the stage 2 inlet is compared to the inlet pipe. Ideally you want the pipe to be bigger than the inlet to the turbo and to have a smooth taper in to the turbo (think bellmouth like a carburetor). Look at most aftermarket turbos and you will see the inlet pipe seals against the outside of the compressor inlet, not the inside like the stock turbo.

If the inlet pipe is smaller diameter than the stage 2 inlet then there will be more opportunity for improvement. I wish there was 2 studs for the intake pipe on the outside of the turbo, but we only have 1. That would allow a larger inlet pipe and to seal it with an o-ring on the outside surface of the turbo instead of the inside surface like stock. Then we could run a much larger intake pipe and have no issues. A few of the limitations of the stock turbo are what make me think about going with an aftermarket turbo, but the stock bov/wastegate are nice being electronic and you would lose that.

Tnx for detailed explanation Jet.

I guess we have to wait and see what stage2 turbo brings. I would be happy with 500whp anything over that is a bonus!

I have a PTF/Cobb tune and here in CA the premium gas is only 91 octane. I will be installing Pure stage 1 turbo and inlet pipe next week, then will send some new data logs to PTF for review and new engine map if needed. There are a couple of stations that sell racing fuel (100-101 octane) around here, might experiment w/ higher octane blend after that. I can let you know how it goes if you want.

still seeking FBOpure either map 2 or map 5 or even 7 for that matter on 93 OCT for data comprehensives.

Post in here or feel free to IM me on the board. thanks

I'm running pure turbo on fbo F30 on map 2 daily on 93 oct .. What data do you want ? On map 2 and 93 oct timing is kinda shitty .. And depends on quality of fuel some times it's not even acceptable .. And I drop it on map 1 .. I haven't dyno yet .. On 93 but was thinking to do as their wasn't any dyno on pump gas alone .. But I wont expect too much power on 93 15whp - 20 whp max over stock turbo ..

I may have 93Oct map 2 on my vargas setup if that's OK with you? Unless you specifically want pure? But their both the same so up to you

yea either would work. i'm just interested in pwms and afrs

[Porkay M]

I ordered but have not installed the inlet pipe on my stock n55 turbo. Why would more flow possibly hurt performance. Should i be worried about installing this on a full bolt on N55?

Btw I have noticed after putting stock intake back on that my PWM is lower with the stock intake compared to BMS intake. So I am running stock intake currently.
