Wortec Head and Cam Pac (for LS1)
Discussion
Anyone had it done?
What is it like versus the supercharged option?
Once you inevitably get fed up with nearly 500 horses(?), can you get more?
I have driven turbo charged cars before and they make me feel sick. I think it is because I tend to keep revs below 2k normally, only opening it up when there is room, but the surge you get from the turbo, although nice, is a bit tire sum. Desiesals likewise. I know a SC is crank driven so no lag... but is there the same turboness feeling in pickup?
Anyway, the idea of a NA route is quite appealing, however the SC means you can change a pulley & re-map and get more grunt (at the expense of longevity I guess).
Does this pack move the peak torque higher up the rev range? Will it be more like a Honda than a LS1?
Can you still get in and drive 200 miles to a meeting and 200 back and go spoonbendingly fast when you want to? Not much to ask I know!

I posted a dyno chart a few days ago from my head/cam package. Torque isnt as high, but with the right cam you wont lose any low end torque. Its plenty fast for me. It will break traction from rolling start in 1st and 2nd. Plus if you end up deciding to supercharge it insane things will happen.
One point to bear in mind, is that the S/C will return the same or even slightly better mpg (when driven on a like for like basis of course) as the standard engine. With the head/cam package mpg will, I'm sure, be significantly less all the time.
Personally, I always prefered the linear torque delivery of the S/C over the slightly lumpy feel you can get with a faster cam.
This is based on my experiences with 4dr HSV's & I haven't driven a car with the Wortec mods.
Maybe worth mentioning that with the intercooler etc. etc. on my S/C HSV I had 100% reliability.

.. not necessarily the case.
Anything that increases efficiency and decreaases pumping losses etc will help econonmy.
I have not lost any economy over stock. Compression has been raised from 10:1 to 11.2:1 which helps enourmously.
I agree a larger cam will not be as economical around town. But I dont think anyone is advocating large cams here.
valve overlap at 0.050 is -6* so its a pretty efficient cam. I think Raggy also has a cam, perhaps he cam comment on economy too?
I still get 400 miles to a tank.

Have to say the H/C pack is damn good - I had it first and drove over 20,000 miles with it.
It is a different drive by it goes like stink. In my last days with it gave a DB9 very seriosu worries!!!
Cruises great and punches very hard with a 3.9 diff.
The sweet spot (unless it has been changed Roger??) is 40mph in second hold and nail it. I think this is what teh millenium falcon must have felt like when it worked.
Have a drive you won't be disappointed

YEp rich your specs are right re H & C. As you say you can better Heads but you pay more - maybe the Wortec kit uses AFRs or Ported LS6's?
With those it will produce over 500hp no problems.
Have to say I never got 400 miles to tank of fuel even if vast majority was motorway.
Mind you on motorway had to give it some beans every so often to deal with pesky rep tailgaters or chavs in 4x4 rallywagons. Motorway cruise frop to 4th and bury it and the car wwould punch forward destroying most things.

Drove the Monkfish demo car with the pac today and I was impressed.
It revs really well, pulling good and strong all the way to 6,500. There is more than enough low down torque, the idle isn't at all lumpy and the average mpg read 22mpg. It was very drivable, very controllable and pretty dam fast.
It had the 3.45 diff in so wasn't quite as urgent as I was expecting, but after getting back in mine you could tell the 70bhp or so difference even with a 3.7 diff.
The car also had scan gauges so it could calculate your bhp on the fly... just like a Veyron!
I think N/A is going to be the way for me, but when they get the SC back on their demo car I might be persuaded...
