What I need to do is record a pull in a gear say, 3rd from 2000rpm to red line at 90% and full throttle back to back. To test if the TB is a restriction yet.
Maybe just a data log and compare the time from 3000rpm to 7000rpm.

Im not sure what size the 1.6 throttle is, but I bet a 62mm Honda TB would work really well at this power level. Dont think Id go any bigger.

Well, here they are, will ceramic coat the manifold and wrap the whole thing in fibreglass and see how it changes the spool up.
You can see my attachments I took a few photos and uploaded them a few times, I couldnt get a clearer one up but you can still read it all.
Let the arguments commence. And the backpedaling, that too.

NOTE, the AFRs were cleaned up a little before it left the shop, however its not a straight line, it made the most torque with most of the swings you see there.

Nope not at all. Look at the damned sheet, it made max power at 11.8:1 AFR, it was already a safe tune.
Not even close.
Good try though.
The tidying up fixed the slight dip at the very top where it goes rich for a second and subsequently lost 4 or 5 odd hp.

Edit:
Nevermind
So yeah, a tubular manifold spools slower and makes more power with shitty AFRs than a log manifold with even shittier AFRs.
Some real groundbreaking **** here.

No idea. I don t really know enough about it.
The bit at the end you talk about where it goes up and down a little is the bit we fixed up.
We did a couple more runs afterwards but no luck breaking 325, got a few 322 and 324hp runs.
I'm just following the trace adding and removing fuel and following what the dyno tells me and the operators experience when he thinks I'm making a mistake.
It was hard to get it on boost at the bottom and that odd fuel curve reflects it.
Heres some SR20 love to help bump the thread

because apparently ftlb in AUS isn't standardized. But I'm just going to assume they are NM or KW or whatever. But that still doesnt added up since 498Nm in Ftlb = 367.26. The dyno shows peak at ~5100, if you go by the HP figures it's showing, then peak ftlb would only be around 312, not 367... dun dun dun.
the dyno is also showing 427% correction.

notice the ft-lb per MAP. He's hitting 80 ft-lb per MAP in some places, compared to Paul and Soviet's setups (both averaging 65 ft-lb per MAP, which is typical on these motors).
Basically Nitro is blowing them out of the water in terms of how much power he's making per liter of displacement. And far supassing the "magic number."
one hell of an efficient 1.6L you got there!
