Per the title, mostly stock NB8A

Mods:
Coldside 3in intake
NA8 HKS 4-2-1 headers (Egr deleted)
80cel high flow cat (welded into oem midpipe)
Muffler from an SE
Adaptronic select plugin ecu
Tuned for BP 98ron


Also worth noting it's a hub dyno, which I think reads higher than roller dynos. (Hell, I really doubt I've got 85rwkw from just an intake)

hks, my NB8A is very similar to yours & dyno figures are almost exactly the same. But on a roller dyno.
114.6 rwhp (85.4 kw), 101 ftlb (137 nm)



Stock except for:
4-2-1 headers, egr delete
Custom exhaust, no cat, resonator & muffler but in almost a straight line from headers to end tip.
K&N intake/pod
98 fuel, but stock factory ecu (JDM import)

I don't take much notice of absolute dyno figures. This was just a check, after buying it as an unregisterable track car, to see if all was ok before hitting the track. I have a dyno printout from the previous owner (car with same mods), & it showed 132 rwhp!

Yeah dyno numbers are mainly just a comparison on the day thing for me too.

Power wise yours may have a little more than mine, mainly because mine still has the factory midpipe, and my dyno runs were done on a 30degree day, so far from ideal.

Tune wise mines pretty similar to stock anyway (just needs a little work on transient throttle, but I'll chat with the tuner and organise that to be done) the ecu was mainly future proofing for when I get off my bum and put bigger cams in.

Hi, what differences are there between the stock and SE muffler?

Haven't done a back to back test to see if there's any power diff.

I doubt it would do anything, the stock midpipe is likely far more of a restriction than anything.

I mainly got it for a bit of sound without being obnoxious like my old rsr was.

Ah okay. Are they 2" or 2.25"?

Didn't measure it sorry.

Lines up with factory NB8A midpipe, so its probably the same as the NB8A.

If you ever do measure, let me know. Also, good taste in the CT110. I'm hoping to restore a C90 one day
