you happy with that Dirk?

What’s cam specs?

Yeah pretty choppy down at 620 RPM, gets a lot of attention at lights and at Macca’s drive through, but too much to bear all the time.

The good news is that I am regularly logging over 1g acceleration in a 2100kg car, which is impressive.

I’m happy with the power and the torque and the acceleration and speed that’s fantastic. The non-idle fuel consumption is not bad (around 500km per tank at the moment), but the idle consumption and manners are not what I’d like in traffic.

I bought a MAF from an LS7 and threw that back in the mix, upped idle to 750 RPM. It is a little more stable now.

So it’s a case of looking to logs and allowing things to trim, adapt, and settle at this stage, I’m confident it will be smoother still.

Intake opens 50° before, closes 63° after (293° intake duration, 46° overlap). Centreline is 111° – 160° continuously variable +/- 49°

^12.4 in a car of this weight is pretty bloody stout, nice work

As Gary said Pretty Stout Car

Can you explain the constantly variable compression? I assume you are talking dynamic compression? Unusual to see someone go down the road of an engine build while retaining DOD/VVT/funky electronics.

Thanks – stout is exactly what I had in mind – more of a brawler / hauler, daily hardened battle horse rather than a skitty one-trick dyno pony staged carefully on rare air cold mornings when the stars are perfectly aligned 

I specified the engineering design to run at high speed under heavy load comfortably for days on end efficiently. It’s not a goal shared with most V8 brethren, but I dig the variability of putting around economically and quiet during work and open up like Beelzebub when I want to play.

Sure, the static compression is 14 while dynamic is 12.45 with cam parked at full advance.  When the VVT phaser is commanded to manipulate cam variables (mainly intake valve closing) it changes the dilution levels and VE of an engine at certain operating points. This in turn affects compression ratio, rpm range, fuel economy and emissions by bleeding down pressures and in effect reducing trapped mass.

You still only have a single camshaft?

So, effectively when you alter the cam timing it doesn’t only effect  IVC (to control dynamic comp) but it also effects IVO, EVO and EVC events.

Correct. Duration and lift and LSA stay the same, main impact on combustion is through calibration of the intake centre line.

While the other three valve events are phased in unison by the same amount, IVC is by far the most influential.

Packed to the hilt, Coffs Harbour to Sydney (Pacific M1) on e85 averaged 8.5l/100k – best ever. 10.9¢ per km (rip-off $1.29/l at Coffs United). Previous fill was $1.03/l at Mackenzie Caltex.

^ dude I dont know what your smoking but….

Only kidding, one day when your over in the Barossa again we have to organize a catch up and drive in each others car

Meth. Not even once

[pir4teParticipant Mallala640 HP hyper-cruising SS-V Flagonwagon View build HERE Member since: March 2, 2015 Posts: 154]

Methyl is for kids who don’t know better, the best alcohol is ethyl – an easy, cheap and safe opiate, both for the Black Pearl and wholesale consumer markets.

Shiraz and Mataro blocks at Light Pass, Grenache at Vine Vale and Eden Valley.

Be consumed.

No Riesling blocks at Eden Valley?
