So basically my fitment issue boils down to the aftermarket turbo outlet rubes were slightly different angle than stock leaving a tight fit for the outlets. We twisted them to fit the clamps and twisted them back to get the clocking correct. We are also vacuum testing both of them to ensure the clocking is correct. Problem solved and not an MMP design flaw.

It's not just a silicon coupler. The proper outlet set ups like VTT have a reinforced material specifically designed for boosted applications to avoid flexing. I can't speak for the others since I simply don't know but I'd imagine they follow a similar concept.

Hey guys,

First off I want to thank Mauricio and MMP for offering a kit. He is a good guy and offers great customer service.

So I have some bad news for the e89 guys, but some good info for you.

We tried installing the outlets on my E89 Z4 according to the instructions. Long story short it didn't fit, literally round peg, square hole.

Before we started one of our concerns was the Wagner 5inch intercooler. It is in stock location, and uses stock connection between intercooler and HSCP. Anyways we said to ourselves we'll cross that bridge when we get to it.

Let me tell you step by step.
- First we went according to the instructions and everything went smooth from turbo adapters, elbow, long/ short pipes.

- How ever when we got to the Y-pipe and 3 inch pipe we noticed the positioning was off. From the bottom it was much closer to the intercooler. Maybe 2 inches length away, but 2 inches or so higher and offset. We cut the 3 inch pipe hoping the extra space would allow for another pipe to be inserted. There was no way the to connect the 3 inch pipe to the intercooler.

- After cutting the 3 inch pipe we decided the available space was too tight, and a metal pipe transition needed would too complicated to fit.

- After bouncing ideas back and forth we decided to start from the intercooler and work our way to the turbos. We knew we could adjust the upper pipes as needed after.

- We used the lower rubber flex section from stock HSCP. This gave use the connection we needed for the intercooler, and flexibility to meet the 3 inch Y pipe. At this point we scrapped the 3 inch that came with the kit, and replace with a 3 to 2.5 inch transition. The Y-pipe and stock flex section would both go over this 3 to 2.5 piece, almost butting at the seam.

- This actually worked out connecting intercooler to the Y-pipe, kind of. The space is very tight and we had surface contact on some coolant lines, and frame rail.

- When we got back to the top we began reassembly. The long pipe fit fine, but the short pipe was touching the exhaust manifold, and also was slightly off in relation to the Y-pipe.

- We played around with pipe placement for quite awhile and we almost had it.

- At this time I asked if the overflow tank, etc would fit? Everything looked very tight.

- We began test fitting the overflow tank and BAM. This was clearly interfering with the Y-pipe. There was too much obstruction below the Y-pipe so we couldn’t get it any lower, or move it and farther forward.

- We decided to cut our losses and revert back to oem.

- After comparing the photos on the install instructions to the Z, we noticed that the Z's intercooler is much closer to the engine. This meant less space space overall all, and also the other components were compacted. We had different lines in the way compared to the E9x layout.

Anyways I hope this helps for future development. I attached some photos for reference of our all day ordeal.

My loss is your gain. I have a full kit available for anyone interested for $200. I have all components plus the 3-2.5 transition piece I mentioned earlier. Oh I also wrapped the long pipe in gold heat reflect tape to protect it from the exhaust manifold. PM me if your interested, local NY pick up preferred.

On a side note. Since we had to put the oem pipe back, I decided what the hell, I'll wrap it in some gold heat reflect tape I had lying around. On the first drive I noticed my temp was 1 notch below 250 during my ride home. Usually it hovers right on the 250 mark. Anyways not sure if its related. Just an observation.

Thanks,
Jake

O man, sorry to hear Jake but good info in case MMP wants to make these for your cars in the future.

Well after days of fighting with the outlets in my garage i finally finished the install on this ...

Butt dyno loves the mod. 'Feel' better throttle response, less lag in power delivery and more powaa.

However beware install is a b*tch. Tight space, big pipes... Never mind. You will all see.

If you can afford to pay someone to do the install just pay. If not.... Make sure you have a lot of time on your hands and lots of patience go make it work.

Again... Love the mod.... In fact bov even has a diff sound at low rpms.... Very subtle. Similar to the inlets sound but much lower.

Waiting on tuner to finish fine tuning things before a dyno run.

Good luck to all

[Team503]

Alright, I'm convinced. Order placed. Will be a while before they get installed, tuned, and re-dynoed, though.

Hey guys -

I've looked at some of the comments in this post and I'm curious whether there is finally agreement as to the performance benefits of outlets?

I'm also curious if anyone has run them on a car WITHOUT inlets and whether there's any really benefit there? I like the idea of modest performance increase at lower PSI, but don't know if that's shown/agreed to be true where no inlets have been installed..

Thoughts would be appreciated?

I don't recommend these without inlets, no benefit because you are choked on the suction side which is worse.

On the *********** forum there are some before/after results in a thread from somebody with the vargas outlets. I think it's in the vargas outlet thread. Dynos and all.

[AaronZ34]

That was a dumb question. There are dynoes that show a significant power gain, at less boost, with a lower WGDC. I'd pass if I were you, they don't do anything.

No gains here. Nothing to see. Move along.

Mauricio, any chance of getting silicone inlets without the DV bungs? I'm interested in purchasing your silicone inlets and outlets, but would prefer not to add the turbulence caused by the DV bung on the outlets since I run a BOV.

Thanks.

[AaronZ34]

His outlets don't have any bungs.

This is not really the thread to discuss the inlets but I will go ahead and answer. The inlets come with DV adapters or plugs so that you can choose which config you want.

Will the outlets fit a VRSF FMIC?

MMP outlets do

Yes cause I believe I read vrsf is a 3" on that side.

Mean, on the other hand is a 2.5" on helix fmic. So I'd need an adapter.

We will provide the adapter to for a small fee, no problem. Also some may need a 2.75" adapter as well for say a stock intercooler, no problem.

[teamraw]

When will the outlets be ready to be shipped out order number #1071

Ordered a set from your preorder on your website. Let me know about the adapter as I need one for my Helix.


Any estimated shipdate?



You still have no plans to make a passenger side version of your inlets like the precision raceworks kit right? I'm going to have to order that kit if that is the case and nothing has changed. Personally I think you could get a lot more sales if you offered it.
