What shows that, the wiggles at the start of the torque plateau?

All I know about dyno sheets is that this one has a nice fat kw figure for an NB turbo. It is also has a nice flat power curve and a flat torque curve. I would like to see the Air/Fuel ratio readout as well.

The bottom graph is a boost pressure graph.

I made a new dump for my NA6-T28 setup which came out ok, did some hillclimbs with worn out RSR's..

Then broke a couple of gears in one of many 5 speeds, fitted a 6speed and finally got a fresh tune from a mate in Sydney who's pretty good with Haltechs..(running an E8) It's running a 4.11 torsen so it's very short with the 6speed! 3500rpm @ 100km/h in 6th.

2 hours later with a hammer and using my Triton Superjaws as a vice and dolly I got this result..

Tune was on pump fuel and 550cc RX7 Injectors. (i'll switch to ID1000's when Ethanol is more readily on the pump. For now the car drives very smooth but lumpy idle 1000-1100rpm as the injectors don't appear to be able to pulse close enough together. It drives GREAT other than the wheelspin in 3rd if i'm a little hamfisted...

It was tricky but kinda like meditation! I love making stuff! (i'm just really crap at it) That's why I built this home-made $hitbox! :)

The exhaust manifold looks alot 'tidier' than that after I chopped off the whole base of the merge/flange and used some new thick wall pipe to make it stronger/cleaner.

Can't take any credit for it as I bought it this way, but here's mine. Completely impractical, but heaps of fun.

Awesome either way, thats a HUGE turbo especially on a 1,6.

What power does it make, on what boost?

Its a 3071 or similar?

Love that intake manifold.
