EFR 6758 + VVT + 19psi = 316BHP/405Nm
 

EFR 6758 (0.64 A/R) with simple welded log manifold. VVT engine (83.5 mm supertech 8.6:1 Pistons, forged, BE oil pump), EUDM flat top intake manifold, stock head, full 3" exhaust. Road-tuned using DIY det cans, running RON100 fuel. I do have some initial boost overshoot that should be taken care of once I get some more EBC closed loop tuning done.

I'm still wondering how to make it spool faster. Those "i want your spool" data sheets make me green with envy.

Starting the pull at 2k will help spool ;)

I did start at 2000, i just cut it off because nobody cares about what BHP i make down there. Did the pull in my 1:1 gear, too.

I got really confused as to why the hp and tq lines didn't cross till I realized that you switched out the units on us!

13 cm will always sound more impressive than 5".

Just a wild guess, the log manifold is hurting spool.

That's my guess too. My plan is to try the Kraken cast manifold next season. It's similar to TSE's, just better available in Europe

That's pretty nuts that it's hurting things in the realm of like 1k!

Will be great to see the difference!

it's not nuts. I haven't seen his log so this is just a guess, but smooth transitions vs gasses colliding into one another is a drastic difference

I mean, this is miataturbo. First things first, you have to show everyone your log!
