3582 .82 Or 1.06 Divided

[Slidewayzzz]

Been reading and surfing forums for months and am still completely undecided. Running a fully built rb26 with 260 poncams, headwork and a forced performance FP3582HTA .82 undivided rear. Goes seriously well and i get full go at around 4500rpm.. Thing is i have this 1.06 divided rear sitting at home and am itching to put it on. Tuner said not to but yea..

I am running a divided mani etc so it will complete the set with the divided rear. I dont want to lose response haha..

Wish there was a back to back comparison between the undivided .82 and divided 1.06 out there! Just cant seem to find the black and white info im looking for.

Yes im looking for more power without sacrificing too much response. Am going for a power check and slight tune touch up in the next month so really contemplating swapping this 1.06 divided rear in..

Anyone have some advice?

What is your wastegate setup?

Tial MVR 44mm single. Manifold is split all the way up to the gate

Not a great angle on the gate, but if you aren't having boost control issues, I guess it will work ok.

I would usually expect a 200rpm later spool, the graph should look much the same, but no tapering off in the top end. Looks like yours barely tapers off, so I doubt you need it, unless you want to stop the torque falling away.

Decide where you want your power band, then make the decision. Most cars don't sit on 7000 revs often on the road.
