Z-Gad Posted November 23, 2008 Share Posted November 23, 2008 Also, is it angled up in the rear or does it come straing back level with the ground? I am just wondering if too much rear downforce will cause the front to lift, creating additional handling problems... Mike Quote Link to comment Share on other sites More sharing options...

v8dats Posted November 23, 2008 Share Posted November 23, 2008 We've finished the wing and it'll be interesting to see how it goes, we are by no means "wing experts" and basicly we looked at alot of pictures and got some basic guidance from a couple of guys. [/img] Hopefully we can get some grip and start to wind the power back in, ROb love it! Quote Link to comment Share on other sites More sharing options...
heavy85 Posted November 23, 2008 Share Posted November 23, 2008 BTW Rob here is where I carry my beer Sorry to get off topic but do you have any details of that trailer hitch? On topic - holy John Force burnout batman!!! Thanks Cameron Quote Link to comment Share on other sites More sharing options...
RIPSNZ Posted November 23, 2008 Author Share Posted November 23, 2008 The wing has been set with about 4 degrees up slope for now, general information suggests we might get about 25 pounds of downforce per degree, I'll start off high and work back down and see how it go's, the wing is fully adjustable and by altering the 4 rods that go down to the bumper we can also change the profile/shape of the rear of the wing if we want. The parachute mounting plate isn't finished in those pix but we have moved it from hard against the body to almost flush with the rear of the wing and angled it up slightly so it deploys upwards into the airflow more than it did before. I'll get some more pix once its all finished, Rob Quote Link to comment Share on other sites More sharing options...
stony Posted November 23, 2008 Share Posted November 23, 2008 If you tow a trailer rob you will need this of course. I'm sure you could get that thing mounted. Quote Link to comment Share on other sites More sharing options...

Guest ratsun516 Posted November 24, 2008 Share Posted November 24, 2008 Sorry to get off topic but do you have any details of that trailer hitch? On topic - holy John Force burnout batman!!! Thanks Cameron Cameron, The hitch is tied into my rear frame rails. I welded a cross bar in-between the two. I did not take any pictures of it while installing it. Not sure why. I do have a few here that I took after the fact showing how it comes out the rear pan. It is the smaller hitch receiver. This is also where the parachute cord attachment slides into when I get to the track. The trailer is a home built deal my brother built to pull behind his Harley. He's been letting me borrow it quite a bit lately. I intend on building one like it and painting it up to match the car this winter. Quote Link to comment Share on other sites More sharing options...
Guest ratsun516 Posted November 24, 2008 Share Posted November 24, 2008 Rob, It looks great! When do you think you'll get to test it? Quote Link to comment Share on other sites More sharing options...
RIPSNZ Posted November 24, 2008 Author Share Posted November 24, 2008 Rob,It looks great! When do you think you'll get to test it? Next outing is a big competition meeting, not this weekend but next. I sure hope it doesn't take long to sort it out and to get some power back into it as there are going to be some seriously quick cars at this meet, Rob Quote Link to comment Share on other sites More sharing options...

RIPSNZ Posted November 26, 2008 Author Share Posted November 26, 2008 Well, after much discussion we decided the best way to cure our traction problems was to reduce power and go back to what we knew, so out with the water to air intercooler and back in with the old air to air, keeps the car looking much the same and at least when we sort out the 60fts and the wing we can look to up the power again.......

RIPSNZ Posted November 28, 2008 Author Share Posted November 28, 2008 We went to get some suspension work done but to establish the best settings the power output needed to be checked. It was great to go on another dyno and have another totally indpendent person run the car up (He happened to be a staunch V8 supporter but he also runs a pro import 7.6 sec supra, go figure!! lol) 1st gentle pull to warm up etc, 1.8 bar, 750whp @ 6500rpm Another pull at 1.8 bar made 937.82whp by 7910rpm We ran to over 8500rpm on another run with more boost and power was still climbing very well at that point so I'm happy that our race rev limit of 9300rpm is about right at this stage. (no details on this run, lost the papers ) The dyno operator confirmed the same flywheel hp numbers we had expected so I was very happy with that but I won't get into what he said power losses through the auto and rear end were, 937whp at low boost and low rpm through a dirty old TH400 is good enough for me. We'll probably run 1.7 to 1.8 bar and work on suspension and chassis geometery to make the most of it before we wind it up anymore.
