If I'm going to do downpipes would it make sense to do inlets at the same time. How much time would it save.

3 x won't. Won't save time. Won't save money. Won't make anymore TQ/HP.

I was under the impression that you’d need to either port inject or upgrade the hpfp in order to run full e85 on N54. Who made your tune?

I’m going to be basically a Stage2 lpfp away from your parts list and I’ve run full e85 on my old Evo9 previously and would absolutely love to do that again, but was resigned to the fact that I could not on this platform without serious investment.

Can you post some logs as well?

You can absolutly run full e85 on just a lpfp upgrade and be fine at the level he has his car tuned its when you go asking for 21+ psi from the stockers that the hpfp starts to run outta fuel and you need pi or a shotgun to get you back up to safe levels, so you can run full e85 with just a stage 2lpfp as long as its tuned right and you dont get greedy

look at the difference in the hpfp numbers

Well, that is good to hear. E85 in Finland is partly made from bio-trash, so it is interesting fuel to me. I’ll first get aquinted with Stage2+ with 98RON and after that see if the flex fuel solution tuned by Motiv ever gets released before I start to play with ethanol again.

Have you guys tuned your own E85 maps based on the MHD ethanol maps, or gone out to make something completely custom?

justin Twisted Tuning is doing my tuning, ive thought about giving it a go myself but for the price of a tune from someone that really knows there stuff is well worth it.

You saying inlets don't make any power and is a waste of time? Why do you say that? I thought they were very restrictive.

Research the subject further. I claim zero to no benifit on Oem size turbo, especially on old and tired set.

in general, miles take a toll on a car, especially a 335 that has been beaten on and hot roded.

If it gets maintained by an enthusiast it will last and live much longer. But he seems destine for big, quick power.

[Tiago@VRSF]

Toss some inlets and an aggressive tune into the mix and you might be able to hit 500 crank HP.

My car was noticeably faster after inlets with no tune. In fact, it felt as tough the car had a tune when it had none.

Now it feels crazy with a tune, although you can tell the stockers lose air up top.

I want bigger turbos now

Placibo effect, no? Post before and after logs and dyno sheets. Then we can revisit the subject.

This is a good thread on inlets and OEM size turbos. http://www.e90post.com/forums/showthread.php?t=1441088

[Chris@VargasTurboTech]

On stock turbos running E85, inlets will absolutely free up some flow and thus a little horsepower. Feuer, in the thread you referenced, perhaps you misread "relocated" inlets vs stock location inlets? They're talking about which type of aftermarket inlets (hot side vs. cold side) not aftermarket vs. stock inlets themselves. The stock ones are fairly restrictive, that much is a done deal.

If it's a mild tune on pump gas/etc might not be the key to victory like they are with upgraded turbos but they're a pretty cheap and effective upgrade.

[arhoads335i]

not to mention inlets let that last 1000rpm shine!! makes it feel more like a NA car at the top by not falling on its face.

[MIL.SPEC]

I have been around turbo cars long enough to know that stock inlets are a restriction. I don't have logs to show, hadn't gotten MHD at that point.

This is why you want more surface area for your filter and an opening/intake tube that is not restrictive. Turbos need to breathe. Conversely, this is why they put restrictors on WRC cars.

If you want to believe inlets do nothing, then go ahead and believe what you want.

This particular platform has people with interesting ideas about turbo cars.

And there's like umpteen posts with dynosheets after inlets lol

V8bait for the tune

https://datazap.me/u/dyezak <---for the logs. We basically limited the load to what the HPFP was able to deliver on fuel. There's still more umph left in the turbos, but the HPFP is maxed.

That's fine though, I'm sitting on a VTT Double Barrel Shotgun and a full dual bucketless LPFP with upgraded fuel lines and flex fuel sensor. Just need to install it all then we can up the load a bit more.

[dyezak]

This is a fun log to look at:

https://datazap.me/u/dyezak/log-1512...log=0&data=0-2

That's a log showing some 0.09sec shift times on the DCT under full load. Shift times on this damn thing are so fast you have to drop all the data points you can in MHD to get MHD to log fast enough to see just how fast the DCT is shifting.

[dyezak]

And then this one shows how the HPFP is absolutely maxed at peak torque (roughly 500wtq).

[Jeff@TopGearSolutions]

You can't just stack estimated HP figures on top of each other and expect it to be the real world result. Lot of marketing BS and other exterior factors equate to power figures and of course tuning is a big factor also. OTS maps won't make as much power as custom tune maps either.

[feuer]

Inlets will make how much? 10-15hp/35-50tq? Past 6k RPM? Something like that? On tune that require Ethanol mix (or straight e85) and boost past 20psi. Well, this 11y old n54 with 130k on the ODO with tired turbos and fuel pumps will not be able to do it. At least not for very long. So inlets would be kind of pointless. That how I look at it.
