Progress Update: How Is BCL's Car Going?

[Mondie]

I’ve told Simon that we should stop at 600rwkw (800rwhp), which is around 1000HP at the flywheel. Time to be sensible, and refocus on other areas for a while.

He agrees.

Your a freak Brian

{l mean that in a nice way!!}

Well... If your being sensibiel, a full body undertray might be worth considering.

If you have a full undertray that is roughly 1.5 inches thick (with full heat sheilding around the exhausts), that tapers up to the rear bumper, you can gain anywhere between 50 - 100kg of downforce at 200km/h...

Might be worth considering.... Expensive yes, but a very efficient, low drag (lowers drag co efficient even, so its like "free downforce" in some applications) method of giving the car some stability.

You will need it.

BTW, how much torque is it making now? Is that 1100 figure up to date?

Can't wait to see what this thing does from here......

I didn't ask about the torque, that why I use +

This is an ongoing project; I'm just reporting progress, and welcome any constructive comments.

thanks

Well, I guess I could give you a rough idea anyway, hang on....

An earlier post asked about the traction and strength of the car.

I would suggest you geta full cage installed as per the v8 supercars. This would strengthen the car, give better traction, handling, and possibly save the car and yourself from total destruction if everything got sticky.

For the amount of money you have spent - it is a small investment in safety.

Has there been any advances made on that 'Zeroshift' caper that was adapted for T5's and T56's about two years ago now?

The info is somewhere on these here forums!

I wish. If zeroshift does half of what they claim it will be fantastic, but I think it will 2-3 years before it's commercially available here, based on what I read a month ago on various forums.

If you jump over to http://forums.nizpro.com.au/phpbb/viewtopic.php?t=91 Simon has written about HP & dynos.

By my calcs, assuming 1000HP at crank, that equates to 729 ft/lb or 989NM (say 1000NM) of torque at 7200 revs. I’d expect peak torque, somewhere lower in the rev range, to be obviously higher.

My other calcs:

1080 NM at 5500 revs

1249 NM at 3800 revs

I'd guess at this stage around 1300 NM

Please correct me if you think that’s wrong.

[Cobra]

it might be wrong or it might be right :o

all that matters is you got a truckload of power and torque ... well done

Brian, have you weighed your car lately ??

[ktford]

Excuse me Mr Brian, but are you going to take the car home & drive her about for a while now.

Whoops, forgot what I was doing.... Hrmm... Ahh yes, excell.... I was going to roughly graph it.

According to my graph, you have a tractive effort at the wheels of about 1110, probably around the 3500rpm mark.....

This is at the wheels, at the crank, yeah, something like 1300nm.

The graph looks fairly funky though, a rather large peak in torque in the lower rev range.... Much more like a dyno graph from a turbo drag/race engine... Oh, did I say that?
