- 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!

Amazing results and thanks to have take the time to test different setup, you give us so much experience. Can't wait to see the difference on track 😁
Thanks Dimitri, can't wait either.!!
Συγχαρητηρια παιδια. Ειναι ενα επος ο Franky και ειμαι σιγουρος πως ολο αυτο αξιζει και το τελευταιο σεντ.
Περιμενουμε καινιουργιο ρεκορ στα μεγαρα. :)
Nicely done, comprehensive test.
Αριστούργημά!!!! Μπράβο ρε φίλε να το χαίρεσαι!!!!
Πολύ καλή προσπάθεια, με απίστευτο αποτέλεσμα! Μεγάλο μπράβο σε όσους το έχουν επιμεληθεί!!!
Ευχαριστούμε φίλε Τόλη!
Very interesting test and results!
Πόσο σε χαίρομαι δεν φαντάζεσαι.
Μπράβο για όλα όσα έχεις κανει και για την τεχνογνωσία
Σε ευχαριστώ πολύ!!
ΠΟΛΥ ΩΡΑΙΟ ΒΙΝΤΕΟ ΜΠΑΒΟ ΣΑΣ ΠΟΛΥ ΚΑΛΟ ΑΠΟΤΕΛΕΣΜΑ!!!!!!!!!!!
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!
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.
Yes, these are the cams : www.catcams.com/products/camshafts/datasheet.aspx?ENGINE_id=350&CAMSETUP_id=2330&Language=english
@@EmptyPocketRacers Thank you! I've been waiting for a breakthrough in BP Naturally aspirated technology. These Cams seem to do what many online say is not possible without bottom end work like a stroker kit or larger pistons.
Did you have to machine your cylinder head for the cams to fit?
@@biggboysouth they say it is impossible because it is.....
allways look at the torque more than 10kg/lt is very very hard
example
integra type r 17.8kg of 1.8 lt 9000rpm one of the best engine ever
s2000 20.8kg with 120hp/lt 9000rpm
bmw s1000rr 11.5kg and 193hp 14000rpm.......8 itb 8 injectors coated pistons and..................
conclusion is yours

This video was super helpful for me, question: where did you get the plenum from? Can’t find anything like this anywhere
@@X_DD I made it, I have a video about that. Thank you!!
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?
Not really sure, bought from Bofi but now they are discontinued. Thank you and good luck with your build!
Was this flywheel power or wheel?
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
Super reliable and super happy so far.!
Hello very nice car and thanks for the side by side testing. Did you use the trumpets inside the plenum?
Hi thanks. I did not use the plenum, I used the dome filter inside a sealed box with a cold air feed from the front of the car. Cold air and volume is the key for performance.
@@EmptyPocketRacers do you have a picture of that?
@@pietersperling81 Like that but with a better hose. I cut my radiator and have the 100mm hose directly infront, I use the filter all the time and it also works very well in the rain. th-cam.com/channels/XoE3kpT-78v6e42tk9b_4A.htmlcommunity?lb=UgxOKtTCPHN6z5PjHJV4AaABCQ
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?
Hi. No problem at midrange, the car actually gained power everywhere. I have a dyno video on my channel with the flattop intake so you can check the diagramm. For power though, static compression is very important so make sure you sort this out. For everyday driveability the only issue was the idle were the car sounded like a 3rotor rx7 😆
I had my engine rebuilt.
Getting
wiseco 10.5:1 84mm
forged conrods
upgraded springs
billet pump
getting there flattop
And I wanted to go with the camshafts, but I got suggustions from a tuner in us that getting the cams with duration higher than 264 will really harm my mid range and on street it would not be a fun at all cause power would be only on top.
@@ReikoX7 No it is fine. Regarding compression aim for 11,5-12 with a forged setup. It is the key for n/a power along with cams.
@@EmptyPocketRacers Head shaving is required for these kinds of compression numbers right? Or can a piston swap achieve this?
@@bagelbytes69420 I wanted to keep oem pistons so I saved the head. Hi comp pistons are also available and along with rods can be an even better solution but ofcourse much more costly.
Πέρα από αυτό τον slipangle ίσως είναι από τα πιο δυνατά ατμοσφαιρικά μπορεί να κάνω και λάθος.
Όπως και να έχει απίστευτο.
Εκτός από εκκεντροφόρους τα υπόλοιπα σωθικά είναι μαμά ;;
Ναι, stock vvt block και stock 4w κεφαλή.
@@EmptyPocketRacers σκέφτομαι να κάνω κάτι παρόμοιο σε 1.8
Είναι αξιόπιστο;
@@fotischronopoulos5694 Ναι, κανένα απολύτως πρόβλημα.
Engine?
Vvt stock block, 4w head.
200 αλογα τροχο;;; δλδ ποσα στροφαλο; συνηθως τετοια ειδικη ισχυς βγαινει με στροφαρισμα 8000σαλ κ ανω
Τα άλογα αυτά είναι στρόφαλο, με κόφτη στις 7666rpm.
@@EmptyPocketRacers μια χαρα, κ παλι πανω απο 170-180 τροχο θα ειναι. miata is always the answer
kai eipa sto instagram story 205hp
Sick Video! Just subbed! Check out my build sometime haha
