Our club had a dyno day, and I got 11.5kw and 13nm more.

Ek stem saam, Francois. n A-series sal goedkooper wees, maar is daar nie limits vir die ou datsun enjins.

Geluk met jou 191.5 kw. 200kw is net om die draai.

There is someone on this site that's boosting 3 bar on a standard internals A14, that's a bit high, but you'll make crazy power on those levels of boost.

Hendrik, why don't you just fidn one or two cheap A14's, and do a j-pipe setup with a large SU. Get the thing going, and even if you blow both engines, you'll be amazed at what you'll be able to achieve on your own, and with lots of help of this site...

Tyrie, I'll go have a look at your graphs, but as I said, things are so hectic at that stage, that you don;t notice it in the way the car pulls anyway. It's a very slight dip anyway, but I'm sure a bigger exhaust will already cure it. Also, I'm looking for a set of the very first 4AGE cams. The engines that still came in the RWD Corollas. Their cams have 0.5-1mm more lift from what I've read, but they have the exact same degrees on the cams as the later ones. That should give a nice and tidy power increase, and might even get rid of that dip..

Only things that's been changed since the last dyno tune, is the boost pipes. They were 50mm pinch bent exhaust pipe on the turbo side of the intercooler, and 63mm pinch bent on the throttle side. I changed both to 70mm stainless mandrel bent pipes, with only about 150mm of the turbo side still being 50mm to make the turn by the turbo.

The car feels different, with boost coming in slightly earlier, and it's more progressive. it doesn't come in with such a bang anymore.

Now I still have to change the exhaust to 76mm mandrel bent stainless. Atm it's 63mm pinch bent, that should realise another 10 or so kw and nm. But I think I'll need a proper dyno tune again, else I might run into lean conditions with flow being much better then...

EDIT: That's still on 0.8 bar boost, and up from 180kw and 270nm...

Baie geluk Francois.
Ek is baie jaloers. Ek wens ek het die geld gehad dan het ek dieselfde conversion gedoen. Dis flippen goedkoop krag as 'n mens eintlik daaraan dink.

Nee, doen liewers 'n A-series turbo, dit gaan jou goedkoper kos, en daar is soveel parte beskikbaar dat jy nooit sal uithardloop nie... Dis wat ek sal doen as ek nog 'n Datsun kon kry...

For the experts, if you look closely, between 6-6.5k there's a slight dip in both the curves, what could that be? I haven't noticed it, because things are happening so fast right then, but I'm sure it's something that affects the overall performance too. I think I read somewhere that it's the exhaust being to small, could it be that, and what about the zorst that's to small causes it, but still allows it to build more power afterwards.

I'll do the 76mm zorst anyway in the mean time, to see what it looks like then...

mine has that dip too, tuner reckons its because I need an exhaust cam.
