You think the 86 heads are bad on the exhaust side? Look at this from the stock head on my GTI if you want a good laugh:


For the record, I don't disagree with you, our exhaust ports are hilariously bad compared to the intake, especially the rear cylinders with that bizarre "S" bend they do.

Not disagreeing with you but I've heard this (rear cylinders) a few places... The "s" bend is on cylinder 1 (Passenger front), and cylinder 4 (driver rear). Very interesting compared to the intake indeed.

its like someone had the highest HP NA FA20, the highest wheel torque stock turbo FA20 and a mustang dyno all in one shop waiting for a manifold to test....

Well the Mark II GTi head was designed a million years ago. We didn't call those things a 2.slow for no reason Sometimes I miss my Mk2 GLI. I had a 1.8 16V many moons ago

Realistically we wish Velox could have enough capital to have its own force induced project car but every bit of funds we do have go right back into developing the platform in other aspects. The result is R&D of certain parts (intake mani in a forced inducted application) takes significantly longer than anyone would like. I apologize for this but we're doing the best we can with what we have.

Thanks for the patience everyone. The one good thing is it has allowed me time to design another concept for an NA manifold. I made the mistake of putting a timeline on this design concept so my mouth is staying shut on this next design . But it is underway.

so basically this project will be done in about 2 years......? haha

My mistake. I don't remember off the top of my head and it's been a while since my header was off.

The 2.slow was the 8V ABA I've got a 16V too... not a 2.0 anymore though

I really enjoy the GTI, I just wish it was reliable. Over modded the damned thing.

Anyway, back on topic!

I'm always the reason we cant have nice things. LOL

I conveniently have a spare set of heads... Which are actually in Eric's possession for mock up. lol

I need to find another set he can use for mock so we can test my spares.

I haven't followed in a while... Did someone break 220WHP SAE on a mustang??? (E85). I still have access to the car I did 220WHP with...

Hey the summer is almost over (at least the 110F+ part). If I can manage to stop breaking everything we will toss it on the rollers =D. I am hoping to have time to slap it on in the next few weeks. I have been waiting on a part from Subaru that was supposed to show up this week. I need to swap my fuel system out to fit the prototype manifold and do some testing prior to strapping the car down. Me nor Eric work in this industry full time so time is sparse between the two of us. =/ Hopefully I can get time before 86fest. But that would just be time to test the current iteration. R&D takes a long time.

@nelsmar yes.

Awww... I guess ill have to try to break it again. Do you have a link? lol

Soooo can I buy this yet?

This is an ongoing development item for us. The OEM intake manifold is proving to be fairly efficient, Subaru brags about it in a PDF I found, should have known better .

Our previous revisions (2) on the intake manifold have outperformed the OEM unit in a narrow RPM band, but overall does not satisfy what we expect from an intake manifold. As a result, there is not much to share. We are moving on to prototypes 3 and 4.

Once we have something of merit, we will share the update. We will continue to test theories and designs until we run out of ideas.

Thanks!

Any chance you could share that .pdf from Subaru? Thanks.
