xsspeed Posted February 2, 2012 Share Posted February 2, 2012 So you'll make a start in a couple of weeks then? Quote Link to comment Share on other sites More sharing options...
flyingbrick Posted February 2, 2012 Share Posted February 2, 2012 I'm keen to hear your feedback on the new engine location once racing starts. Sorry if i missed this- but have you had it on corner scales? Quote Link to comment Share on other sites More sharing options...
LingLing Posted February 2, 2012 Share Posted February 2, 2012 To give you an idea Andy, Steve Wilcock is doing 1:17's in his 150kw N2 86 on full slicks. If I were you, the aim would be sub 1:25ish. right, got that! I am going to master it tho. Quote Link to comment Share on other sites More sharing options...
Truenotch Posted February 2, 2012 Author Share Posted February 2, 2012 I'm keen to hear your feedback on the new engine location once racing starts. Sorry if i missed this- but have you had it on corner scales? Not yet, that's something that will happen when we get around to set up. Why do you ask? 50/50 weight distribution isn't the be-all and end-all of car balance, there's more to it than that... You can get an AW11 to 50/50, but the centre of mass is still over the rear axle. The location of the cenre of mass is important - I've gone as far back as was possible without elaborate sump modification or more firewall cutting and am fairly confident it will be an improvement. If you're not sure about the theory, have a look at the algie alfetta - a car that is well balanced factory, but with the V8 mounted behind the firewall and the driver in the LR seat. It handles bloody well too. Quote Link to comment Share on other sites More sharing options...
Roman Posted February 2, 2012 Share Posted February 2, 2012 Yeah, a car with really long overhangs (like a charger or something) with lead bricks right at the far extremities could have a 50/50 split, but understeer horribly into corners and oversteer horribly on exit compared to a car with all of its mass inside the wheelbase. Ever noticed that most/all modern performance oriented cars have got the front calipers mounted on the back of the disc, and rear calipers mounted on the front? (And a million other tiny, seemingly insignificant details that obsessive engineers have pored over) Quote Link to comment Share on other sites More sharing options...
My name is Russell Posted February 24, 2012 Share Posted February 24, 2012 How did test day go yeow? Quote Link to comment Share on other sites More sharing options...
Truenotch Posted February 24, 2012 Author Share Posted February 24, 2012 Pretty good for those who did it . My car is still in the shed. Will report when something of substance happens. Quote Link to comment Share on other sites More sharing options...
nick_m Posted February 24, 2012 Share Posted February 24, 2012 So not racing tomorrow then? Quote Link to comment Share on other sites More sharing options...
Truenotch Posted February 24, 2012 Author Share Posted February 24, 2012 I'm racing the old man's MX5 with the Pro7 classes this weekend as a tested for a new series. My engine still hasn't made its way into the car and needs an ECU before we can make it go . Work and a summer uni paper got in the way of it this time, but next week's job is to fit all the ancillaries to the engine and get it ready to be wired. There are 4 brand new slicks in the shed now though! Quote Link to comment Share on other sites More sharing options...
nick_m Posted February 24, 2012 Share Posted February 24, 2012 Thats awesome, I just bought some second hand TRS front slicks for mine. Bout to head off this morning and order my 13x9s. Going to be good to get them on! Quote Link to comment Share on other sites More sharing options...
QCADTA Posted March 12, 2012 Share Posted March 12, 2012 wrinkle looks good! are you keepin the plywood? what happens when it gets wet, drys and warps or starts to delaminate? treated or not its bound to happen. Youve done such a good job dont skimp on the splitter mate. Quote Link to comment Share on other sites More sharing options...
Truenotch Posted March 12, 2012 Author Share Posted March 12, 2012 It doesn't really matter what happens to the splitter. It's bound to be hitting the ground etc. I'm going to give it the 'ol diesel / used oil mix as a treatment and see how long it lasts. There's a corolla in SS2000 that ran a plywood splitter for a couple of years without having issues. Same goes for Chester's Commodore, Jason Leifting's WRX, Juno sports cars - the list goes on. My theory is it's cheap enough to experiment with, and I'll look at other options if it doesn't work out. Quote Link to comment Share on other sites More sharing options...
nothingsfree Posted March 12, 2012 Share Posted March 12, 2012 Plywood is still used on a number of high end racecars, for the reasons mentioned by Truenotch. Even F1 cars still use a length of plywood under the car. Alot of GT racecars etc use plywood for their front splitters, sometimes prettied up with a layer of carbon over it. Its lightweight, cheap to replace, and doesnt bite when it scrapes on the tarmac, instead just wearing away. Really keen to see how the new set up turns out. Decided yet whether you are going to take some meat off the head? Other than that, are you planning to change much internally? Quote Link to comment Share on other sites More sharing options...
Spencer Posted March 12, 2012 Share Posted March 12, 2012 Yea its pretty normal to experiment with a plywood splitter, I have seen it on some serious cars before. Adding a couple layers of fibreglass can make it a bit more of a permanent solution and add some strength to it Quote Link to comment Share on other sites More sharing options...
drtdvl Posted March 12, 2012 Share Posted March 12, 2012 Hmmm i might have to look into using plywood... Think it would be any good for a tarmac rally/targa car vs track? Quote Link to comment Share on other sites More sharing options...

Spencer Posted March 12, 2012 Share Posted March 12, 2012 Splitter isnt going to help much when your car is setup for tarmac rally? it wont work unless the splitter is slammed close to the pavement, I imagine on NZ roads you would loose a splitter in about 2min The wood on F1 cars has nothing to do with aero! its a skid block to make sure the cars arent to slammed Quote Link to comment Share on other sites More sharing options...
QCADTA Posted March 12, 2012 Share Posted March 12, 2012 yeah i know that just pointing out it isnt made of plywood. Quote Link to comment Share on other sites More sharing options...
drtdvl Posted March 12, 2012 Share Posted March 12, 2012 Bit off topic, but i noticed a decent differance when i put the e30 lip on. it's held up very well even with being so low. Quote Link to comment Share on other sites More sharing options...
