Question, if we do not get pick for the beta testing, can we still purchase the manifold on your website and how long is the waiting period for one to arrive? In other does it ship a few days after purchase or do we need to wait for the beta testing to be over to receive one?

I'm really looking forward to seeing the final results on this. I'd love to be able to hit 220whp with NA on this platform, and right now it seems like exhaust + fueling only gets around 200, so there has to be intake side work that can be done.

^ doubt it but we can hope.

Dr. BRZ · 06-27-2019, 04:41 PM

I believe its possible but the most gains will come from a custom tune. I'm going to pair the manifold with the grams throttle body and greddy snorkel and see if that combo can pull extra numbers.

Good lucks guys! I’ll be following and will likely get one down the roads if things pan out.

Super curious how this will fair with a proper tune on E85. I can say that my extrude honed IM certainly made a difference. However the RacerX IM is much cheaper than mine ended up costing all said an done.

Yes, you can purchase manifolds now. Currently we are building a handful so lead times can be a week or two but you do not have to wait for beta testing.

I see that you plan to pair it with the Grams TB, which I think is 72mm. Has anyone ever considered using the Toyota Tundra TB? Its 75mm but could be easily adapted to the OEM manifold or we could machine a flange for our manifold. This option would be considerably less money than the cost of the grams. Just a thought, perhaps we will purchase one and see if there are any noticeable gains.

That sound nice.

I am very interested in the tundra tb. Do you know what year would be compatible? I am also down for that flange to adapt to the manifold. Do we get to see the e85 dyno now?!

I have a v8 Tundra TB on my TRD supercharger setup. I think most years will work. I believe the 67mm v6 TB is identical to the BRZ/FRS TB and people make adapters to go from that to the v8 one already. One thing I found is the signals to the ECU are not the same as the BRZ/FRS TB, so it doesn't really work as a PnP unit. However you can swap the motor and electronics from one to the other and it works fine.

This is great info! How much did you buy the TB for? Do you know where to buy those adapters you mentioned?

It came with the supercharger I'm using but you can find them on Ebay, I'll see if I can get the actual part number off it.

URD, urdusa.com makes the adapters. https://www.urdusa.com/urd-throttle-...gr-fe-4-0l-v6/

daninplymouth · 07-26-2019, 11:06 AM

Any further progress with the testing on the mapped cars?
Would these fit UK rhd cars? i cant see any reason why myself.
I'm interested to see what difference people are getting with mods already done, i have a decat manifold and ecutek map, which is very popular here in the uk, if i could gain 15bhp with this manifold and a decat front pipe i think id go ahead and order and put off going FI
