Miata ITB DYNO Test # Plenum vs Open Trumpets # ITB Power Gains

This dyno day was a good opportunity for some testing as well. Keeping the base map at the ecu we checked how the plenum performs, how filters affect power and also the difference of open to closed hood during the dyno run. Then we started fine tuning the ECU.

Franky did very well, hitting 200hp and more than 20kgr of torque.! Konstantinos @akina_downhill did an amazing job one more time squeezing every bit of power througt the powerband. The car feels really nice while the sound is glorious!

[tourvos]

Πόσο σε χαίρομαι δεν φαντάζεσαι.
Μπράβο για όλα όσα έχεις κανει και για την τεχνογνωσία

Amazing results! Do you mind sharing the cam specs for your cat cams? It's amazing you are able to make 200HP below 8000 rpm. Most 200+ BP engines I've seen have required 8-9000 rpm to do so.

This video was super helpful for me, question: where did you get the plenum from? Can’t find anything like this anywhere

[erictol]

Awsome work! I'm planning a similar build. Would you like to share the partnumber of the Volvo valve springs? Is it 418737 for a Volvo B20?

[beratsbuilds]

I wanted to subscribe, but you have exactly 1320 subscribers (that's how many feet are in a quarter mile) 😁

Ωραίος, να το χαρείς, με το καλό να τα πούμε πάνω.

poly kalo to mx-5 bravo na to xareis kai na rikseis kiallo tous xronous sou!

[pietersperling]

Hello very nice car and thanks for the side by side testing. Did you use the trumpets inside the plenum?

[ReikoX]

Hello man I would like to ask you about torque deep for the 274, did you lose midrange torque or not? Cause I wanted to buy these cams but I am quite afraid of street drivalibity as the Duration is to high and power should be in high rpm?

Πέρα από αυτό τον slipangle ίσως είναι από τα πιο δυνατά ατμοσφαιρικά μπορεί να κάνω και λάθος.

Όπως και να έχει απίστευτο.

[traintalkers]

Has it been reliable? I’ve been trying to decide if I wanna keep mine na and go with itbs and make it my summer daily but trying to get some feedback from a couple people
