An "honest" 244rwkw @ 18psi on a nice "safe" tune

[LTHLRB]

Got my car re tuned at Initial D Racing. MASSIVE difference compared to the last tune done at CREATD Motorsports.. Car supposibly made 297kw on 18psi. Ended up making 270kw on another dyno with the afr at 14.5 and climbing.

So the afr has been beefed up and is now at 11.0. @ 18psi it makes 300kw on the knocker with full boost in 3rd gear at 3000 - 3500 rpm.

Externally gates 3076 .82 Turbo.

Tial 44mm gate.

Greddy Profec B boost controller.

JJR Ex Cam Gear.

Apexi pfc w/ z32 afm.

Highflowed injecters soon to be changed to nismo 740cc units.

Std head and bottem end.

Future mods will be New injectors, 044 and Surge tank. FULL RACE type ex manifold and new dump pipe.

Been playing around with the car of late.

previously had

Nismo 555 injectors

greddy profec b

Garrett 3076 52t .82 internally gated 1 bar actuator

Tomei Poncams

98 octane

usual front mount and 3" exhaust

z32 afm

changes

3076 52t with .63 rear

Tial 44mm external gate

made 236 @ 15psi falling to 14 (no boost control other than the spring in the gate)

*there was no tune done with the new rear set up due to going e85 in the next month or so

verdict

boost comes on a LOT earlier, but no issues with traction. I do miss the power in the top end though, really punches coming out of corners.

plans

E85 + 18psi + 740cc injectors should see me back around the 270ish mark and be back to being awesome with great response. anything more and it does start to become unusable. when the car was making 270 it was great on track, but really lacked low end pull

also worth noting a few friends have the 56t version with identical set ups, the 52t has no where near the high pitched spool noise as the 56t, it does try though
