Great info and good points on both sides.

I still wish I picked up 30 g/s. I would poop my pants. LOL

I'm moving from a clearly maxed out CS SRI/TIP to the Sure Full 3" intake next week. I will pull before and after logs to show the difference, albeit on an S3 not a K04 but still relevant. I really wanted the 3.5"/4" HTP stuff but it looks like no reducers will be made to work with the K04/S3 sized compressor inlets.

Any reason why not just go with a htp 3" Inlet with a treadstone 3" housing? Save yourself $80 to $100..

Buy reducer elsewhere? Jbr sells the 3.5" to 2.25" for $25

Silicone intakes doesn't stock a 4 to 2.25 reducer and if they don't have it, it would be a custom part. They do have a 4 to 2.5 that might be worth an experiment if you really want the 4" inlet. The S3 inlet is slightly bigger than stock so it has a chance.

Just remember that it's a tradeoff. You do lose some accuracy on the MAF by upping the size, which can affect the smoothness of partial throttle operation.

Doesn't the beaner run the stock housing? How can the inlet be bigger?

Late at night + unlimited supply of Bear Republic Racer 5 IPA + computer and wallet within arms reach = irrational purchases with little to no forethought.

No it uses a larger Hitachi compressor cover and the inlet is slightly larger. The turbine housing is stock w/ BNR magic machining work.

Thank you for the clarification.

Looks like we will be offering the 3.5"-2.25" coupler as an option. We apparently already have them in stock.

Stock driveability is what we always strive to achieve which is why we recommend not going too large on small turbos. That said.......We have run hundreds of 4" intakes on small turbos in the past using this coupler.
Forced Performance Turbochargers: FP 4" to 2.25" Reducer Coupler

We no longer offer in-house tuning support, so if one decides to go down this path please spend the time to calibrate the maf & tune properly.

The MAF resolution on the MS3 is fairly high compared to older cars so we don't quite suffer from the same issues as older platforms.

[Voltwings]

i keep checking every couple of days hoping to see a 4" intake option

[Zbrit00x]

very glad i stumbled upon this...my WP intake idle is pissing me off, and the honeycomb air straightener is pissing me off more... was going to make my own air straightener..but I guess no need now!

Also after looking at the pic in op, I see that there is no bracket to hold it in place better just as some other intakes have,CS etc. My JBR WP has one but the bracket doesn't line up to the mounting location on the car ( without the bracket you can move the intake by hand without too much effort). Not sure If you guys are adding one on your final design, but Id like to request that it is added, and maybe even have a horizontal metal slider bar that can be adjusted and tightened to reach the mounting hole since not everyone will have the same setups. Just a request that makes sense to me and I would love to see implented ( so I dont have to make my own )

Any more info on this and when it will be out? @HTP;

Sorry, late to the party and regarding k04 with big intake systems:

The 3" FULL AEROS system showed higher airflow through the MAF than the COBB TIH/AEM CAI that it replaced at 93F ambient. This resulted in more power at 93F.

The 3" FULL AEROS system showed similar airflow through the MAF as the COBB TIH/AEM CAI that it replaced at 72F ambient. This resulted in similar power at 72F.

I guess the takeaway is there is a temperature coefficient in this discussion regarding the k04 and intake size discussion. The 3" system resulted in better airflow in higher ambient temperatures down to some temperature point where the performance of the intake systems was similar on my car.

[Voltwings]

im just gonna spit ball here because this is my first turbo car so all the physics arent quite grasped yet but here it goes:

Assuming the turbo does not have to work as hard with a larger intake (lets say anything larger than stock) we are able to hold more boost, up to a point. I was tuning a girl with a Gen1 the other day and she was fully bolted save for a TIP (strange how that happened) and she was doing like 17 psi at redline. We switched her to a 3" TIP the next day and she was holding 19.5 psi at redline, that much has been proven with intakes.

Heres my thought process regarding what Mr. Gribble has brought to our attention: Assuming a larger intake offers less restriction, you improve the pressure ratio across the turbo, which means it works more efficiently and thus, cooler correct? Could we assume that it has made enough of a difference that more power is being made per Lb of boost, may be very very slight, but it seems to make sense.

i dont suppose you would see this gain in power because the MAF does not measure "power" or "density" but simply air flow?

[dale_gribble]

There could be some logic to what you said. My BATs were lower with the 3" setup at 93F compared to the TIH/CAI. That would explain the higher power output.



However, at 72F, the BATs were exactly the same between the 3" and the TIH/CAI. I guess what I am trying to get across is that the 3" doesn't buy the k04 gains across the board; in my case, gains were negligible up to a higher ambient temperature between 73 and 92F. The 3" appeared to have better luck helping the k04 make more power with less dense air.

This was my comparative VD run at 93F. You can see the car made more power and held higher boost with the 3" (blue line).



This was my comparative VD run at 72F. Here, you can see boost #s and power to be similar. The logs were very similar also (green = 3").

[Voltwings]

Yup, looks like what you said in the first place pretty much holds true, that the larger intake more or less helps in the heat. Sooo everyone in Houston where i am needs like a 5" intake haha, December 3rd and its 80* outside -_-

I wonder if altitude also plays a factor a little. I know that @h.h.sk1nny should be at a pretty high altitude. The theory would still be the same, it's just a factor I haven't seen brought into the discussion...and we all know that altitude is a killer of turbos as small as the K04 on this motor.

i live at sea level so i cant say i have much knowledge in that subject matter, just off the top of my head, maybe @PapaSmurf;?

I never messed with larger intakes on my K04.

What exactly is the question?

just an example my 35r is out of steam at 35psi. Where as at sea level I could run close to 40 or more.

We are in the process of finishing up the jig for these. I have a few that will be ready to go this week now that our powdercoater is caught up. If you want an early one, let me know, and we'll PM some special pricing.

@HTP; Will there be a 3 or 3.5" version of this for the people that want to go BNR turbo route?

[dantes5823]

A full 3.5" would be nice.

[Voltwings]

@Toymachinespeed;, you too can has beast mode 4" intake.

[Lex]

We're starting to some idling and coasting issues with the larger intake (3.5" and larger). HTP; please do plenty of testing as with intakes this size small airflow values throw things off since the sensor is not picking airflow up as well due to low air velocity.

It must be different from car to car.

My 3.5 has never had any issues, idling or coasting.

Some cars do, some don't. You're also at a low barometric pressure.

This, I've been waiting to pull the trigger on the HTP 3" inlet to replace my 2.5", would love a 3" MAF housing to complete the package.

No idling or coasting issues here, my issue is it just gets a little silly on shifts. It almost wants to bog and then it kinda picks back up, almost as if you weren't to rev match between shifts, but just let the clutch out. This could very well be related to the "idle/coast issues" but while physically coasting or idling its fine. It may be i just need to adjust my throttle tables and or driving style since at the same pedal position less air (velocity at least) is being brought in, who knows, it just went on last night so ill play with it.

BTW, thanks for the tips about the idle issue, cleared out everything below .9 and bumped up the idle a tad and its smooth as glass.

[superskaterxes]

do the people with idle/coast issues and 3.5"+ intakes have a honeycomb?

Most cars handle the large intakes just fine but some cars do have issues. We have one here in the shop that we're working to come up with a tuning solution for. This has been the only car that has taken extensive tuning to fix with a large intake. Why there are problems with a select few cars I haven't figured out yet, and that's the reason I've been delaying the release of our large intakes. The first couple of 4" intakes that we send out we are wanting to make sure that they get into the hands of those that are proficient with tuning or are working closely with a tuner, so that if any tuning issues pop up, they can be working on a resolution immediately.

Raising the idle is an effective way of increasing airflow.

For shifting, do the AFRs go very rich? If so, lower the shift clutch in/out tables. Multiply them by 0.5.

Matt, compare the voltage readings at the MAF sensor for the cars that have problems with the ones that don't. Contact me with the info.

i do and it doesnt so shit

[Etipp98]

My WP had issues pre honeycomb (coasting only), but after I put the honeycomb in and at the same time did the zeroing of the maf tables under .9v, my issues went away. I'm ditching the WP after I get my hands on one of these.

I have had issues with just a 3"....honeycomb has definitely reduced the effects...but I still see trims getting very high when coasting in neutral at speed.

Got mine today! Thanks @HTP; !
Already installed, just need to take some pics and get it on the road for some tweaking!
