I hear Duke Nuke'm Forever is being released soon.

They rang me! Apparently the last of our stuff is being dispatched this week...

*falls off chair laughing*

[SouthJ1]

I really have been reading up on this and this will be very helpful

[Robbomaz]

Well we are still waiting for fewell rails from SA, but we are pushing ahead with #1 - not pretty but will work fine
REALLY must tidy up the shop - might allocate hours 25 & 26 out of each day to that

On the dyno soon

[johnnyapollo]

Looks like they changed the drive design (went from cast to billet back to a new casting). Can you take some measurements of the drive (nose)? Also, is the unit still an MP62 or is it another model? I'd like to get mine put back on and I'm trying to decide if I want to replace the drive or have it rebuilt (not sure if the cast nose is worth rebuilding).

I'm pretty sure its MP90... looks like it + see the beginning of this thread

[johnnyapollo]

This thread's been going on so long that I don't remember it from others - thanks for the clarification...

[Robbomaz]

It is an MP90. This snout is cast. We've done some machining on this particular one.

John I will have snout/pulley offset dims soon but this snout has been machined down and we have moved the SC position on the manifold so our measurements won't help you.

[johnnyapollo]

Got it, thanks.

OK lads here it is..............and the results have blown us all away

Car ran well right out of the box - we've lost the graph of this actual engine but from memory it was 134 hp, not too bad for a 430000 km 6VE1!

130 hp graph is a stock 3.2 SOHC

166 hp is 2 psi

188hp is 3 psi There is a caveat though - the 188 hp was at 100% injector duty so that is the absolute limit of the stock hardware, real world tune with stock hardware is realistically about 177hp

The SC is hardly working at all and there is a 25%+ power gain, and more importantly the low rev power is well over stock!

More work to do but very very exciting

Nice, get some bigger injectors in there and tuned with a piggyback system (say a megasquirt or something similar) to get DC around 80-85% at full boost, say 8psi, and it'd be making some good power! Is this on a chassis dyno I take it? And is it running through a 4wd auto trans?

It is a chassis with a drivers seat on a chassis dyno
We are still working on cracking the ECU, got to where we can see the tables, but can't yet tell what we are looking at! Not keen on piggy backs - (we are Haltech agents) but not ruling it out.
Certainly the potential is there for quite a bit more power above what the factory hardware can deliver

You can also increase fuel pressure for additional fuel up to the point that the ecu can still lean it enough when off boost.

After a certain point fuel pressure becomes diminishing return though and only atomises the spray better.
