I part own a dyno now so will eventually get it strapped down and figure out what the power and torque curves look like.  Starting to get a bit nervous about drive train holding up.

Look forward to seeing that, as you say, everyone loves data! :)

Cheers mate! Yeah I'll post more data after this weekends event.

Im using a customised C56 - its got some hybrid parts in it and a few custom machined bits and pieces.

Well had this thing out earlier this month and gave it a good thrashing at the track and it ran faultlessly and Im super happy.  It was a pretty hot day and unfortunately the track was quite slippery so I wasn't able to get a good time in but was super happy with how it ran. I was running full interior and full exhaust for the day and didn't use boost per gear or launch control as I ran out of time to configure it all. But it was still a great day with friends and netted a best time of the day of 12.5 on a 2.8 60ft @ 120mph - yes it was that bad off the line.  I tried all sorts of different launch rpm and even went back to launching in 1st which I don't normally do. Best 60ft I ran was 2.19 and that was after a big 2nd/3rd gear burnout to get the tires super hot.  I think I need to get more savage on the burnout to get the tires really hot, then also give them a quick scuff before staging.  Ive been too  pussy on the burnouts as I'm worried about drive train but it seems to be holding so may as well try next time.

I was looking back at the notes on the setup when I ran the 11.8@121mph and I was running the side pipe and it was a night event.  I've got an idea the exhaust is a slightly restriction so I think the next step will be to finally build a 3 inch exhaust as its currently running 2.5inch with a muffler and reso.  Ive also got a new turbo on order so that should wake it up a bit, plus im piecing together a 8.9:1 bottom end as this one is 8.0:1 so a little lazy.  I'm going for a good responsive package rather than outright power.  

Anyway, here's some photos:

Last month I took this thing out on a cruise to a Japanese Nostalgia meet that's held every year.  Threw the kids in the car and went along to check out some other cool cars from the era.  Super fun day, the car ran pretty good and drew a bit of attention.

One of my work colleagues brought along his tidy 4agte Levin which I have since dyno tuned for him - super simple un-opened small port 4age with a gt2860 (Stock S15 turbo) and a Link Atom.  Managed to run a very conservative 160kw on a touch under 12psi.

In other news, Ive got a new turbo on order for the starlet and also have bought an AE86 so will set that up as a nice simply street package for now.

Didn't think anyone read this any more :)

Its this thing.  Facelift Levin, slightly tweaked 16v with some headers and HKS bits, T50 5 speed (possibly close ratio), LSD etc.

No major EP71 news to report other than Ive bought some stainless 3 inch bends and straight to make a bigger exhaust.

AE86 has been taking any available time, engine is almost ready to go back in.

Still have the EP71, havent touched it other than the odd drive - its still scary.

AE86 is painted, slowly piecing it together this summer.

Few other small customer jobs to finish then back into the EP71 next year once the AE86 is legal - have some upgrades in mind.
