The ITB FE3 Dyno
Motor is mostly stock with just a few bolt ons, track car so doesn't need crazy power just has to work all time.
JDM FE-DOHC (technically the fe3 is a kia motor, mine is an actual mazda motor)
FE3 matching cams, 9.1mm lift ish 240 duration, fairly tame
diy 45mm itbs w/ported intake manifold, off a 2005 GSXR 1000
4-2-1 ss header
2.5" ss exhaust

Fucked if I can remember how to embed it, w.e
Picked up 5whp with some timing addition, leaned out the top end a bit, nothing to crazy.
Only thing Im curious about is the torque falling off so fast, cam limited maybe?

Yup exhaust is mandrels, very free flowing, which accounts for all the noise it makes lol
We played with the timing on the dyno and torque was by and large unaffected up top. I'm 30-34deg on the top end

Why's that? I doubt it will make any more power, then its just a waste of money.
I'll be doing a mildly built head this winter with cams and valvetrain then ill redyno it to see if my torque still drops off so quickly. I'm thinking the cams are choking it out as the motor was only ever rated for 140bhp and I'm making more than that at the wheels, in a rwd car non the less

IIRC the 2L is good for spooling a larger turbo faster. the rods in the fe3 are super stout letting people get away with tons of power on stock bottom end. Both those are advantages for boost. Not n/a.
N/a that plot looks kinda similar to a bp4w/bp6z with bolt ons: about the same power and not much more torque.
Someone correct me if I'm wrong of course.
(and I don't mean this in a disrespectful way)

The plan was always to boost it but I was way to busy this year with work and I was convinced to keep it n/a for reliability.
The motor is definitely suited more towards boost but for the price of the motor and all the parts being around $1000 I'm pretty happy with the results.
No one had done this setup before so I figured I'd try it out and see how it worked.
I have a fresh holset turbo begging to go on but ill have to look at classing before I decide

Sounds brilliant.
The torque drop off could be anything… Intake manifold? Exhaust manifold? Cams? General design-ness? Probably a combination of everything. Still sounds awesome though.

Not sure on the bigger primaries, but you may well know more about such things than I do. Shortening the secondaries should, in theory, push the torque curve further up the rev range. And that's about all I know.
