Turblown Intakes and DBW

I hopped on the group buy for the upper and lower intakes. I know 30+ years ago Mazda engineers made the most awesome manifolds, and some will never stray. Not here to change minds. As always, Elliot has shown me his dedication and given me his time to talk shop, and answer any question I have. He is getting great results with this setup on the dyno. And gains from efficiency are much better than gains from boost, and tuning to the edge IMO. Furthermore, you have upgraded vacuum connections, which can save a motor. Ditch the block offs, that can be failure points. They look better in my opinion. You couple this with the DBW kit they are developing and you mitigate the need for the butterflies in the UIM, the need for coolant up top, and get a great idle and tunability. I won’t speak to his plans for DBW, but it sounds on point as far as sizing, performance …. and price.

Please find a shop that has such in demand products, is doing R&D, and still gives you their time. I am giving credit where credit is due. Also, helping people who may be considering upgrading their UIM or TB. Maybe I am funnier than I knew.

Been watching that too. Seems like an interesting development and they are posting some interesting results. I am not their target market but interesting nonetheless.

@R-R-Rx7 i'm curious why you're not a fan

I am not a fan of the vendor. he is a lying POS who offers garbage and never owns up to his MAJOR **** ups. as for the results, i have seen plenty of fabricated "results". So much for that R&D.

On a side note, i did see the manifold in question in person in a shop i used to do some work for... the iteration i saw, will never work.
besides, its been going on for what, 5-6 years ? probably more?
so what's the status?
he is taking orders for it?

GOOD LUCK LOL

I have an intake coming. We will test it on a bunch of cars here and see what the results are. We have Typhoon, Cosmo and obviously stock to compare it to. Bunch of track cars with known times, all the gains we can reasonably find are appreciated. If it's ****, then it will be ****. You can't hide real results.

If you jump in early, you might be wasting money. We won't know until it's out and tested.

The stock intake was designed for less overall power, so it's not that Mazda engineers did a poor job, it's that they did a great job for a ~280hp motor, not a ~500hp motor like most of us are aiming for with singles. If you're planning on running stock boost then yeah it's a stupid place to put your money.

So far, we have Turblown provided dynos. There's not much point in debating it as is.

there was another thread on it several years back:

https://www.rx7club.com/rotary-car-p.../#post12515491

it essentially does nothing until the very top end. My bet is that the pic below would do the same thing, especially after the divider has been cut out and a non-staged TB is installed (none of that is revealed on the Turblown dyno posts, “OEM” is the only vague reference point):
