David[RL] Posted January 6, 2008 Author Report Share Posted January 6, 2008 small update.. if anyone is interested in how the progress is going welded in equal length 4link with uniballs at both ends also did make a new section for the diff/tailshaft because the car is so low it got smashed by the diff/tailshaft considering making new rear wheel housings, but that depends on what types of flares I will run.. I will really need some wider tyres next season cusco pipe A arms with uniballs, and adjustable (bump steer )tie rods also uniballs only thing left in suspension not using uniballs/spherical bearing/pillowball or whatever you call it is front and rear sway bar, I will change these to custom adjustable swaybar using roller bearings later, but for now stock ae86 will do have also bought a blacktop 20v engine and I got some special cams from TODA which are custom grinds, I won't tell the specs, but I know a guy that got similar cams which I have documented proof of 202BHP on a 100% stock blacktop 20v ( except the cams, valve springs and cam pulleys) I will aim for alittle more.. about 210-220hp using VEMS ECU, and E85 fuel ( 85% ethanol, 104 octane ) Quote Link to comment Share on other sites More sharing options...
LittleRedSpirit Posted January 6, 2008 Report Share Posted January 6, 2008 Whats the 85 percent ethanol fuel like, have you always used it? Quote Link to comment Share on other sites More sharing options...
David[RL] Posted January 6, 2008 Author Report Share Posted January 6, 2008 Whats the 85 percent ethanol fuel like, have you always used it? no, I have never used it, except on a 4K engine just for testing E85 is 104 octane, cost is 8 NOK/litre shell has the best regular fuel which are 99 octane for 12-13 NOK/litre the advantage of running E85 is that it runs much cleaner and cooler and gives more hp http://en.wikipedia.org/wiki/E85_in_standard_engines Quote Link to comment Share on other sites More sharing options...

Seems like a lot of risks/engineering required to make it work but Ill be impressed if you can. How do you expect to get so much power when its only 3/4 as explosive as petrol? Youll have better mileage... Edited January 6, 2008 by LittleRedSpirit Quote Link to comment Share on other sites More sharing options...
David[RL] Posted January 7, 2008 Author Report Share Posted January 7, 2008 Lots of good reading there. Seems like a lot of risks/engineering required to make it work but Ill be impressed if you can. How do you expect to get so much power when its only 3/4 as explosive as petrol? Youll have better mileage... well, the E85 contains about 30% less energy, that is solved running 30--40% richer fueling :P another big advantage of using E85 is there is no carbon buildup in the compression chamber or exhaust pipes it burns so much cleaner it's almost like race fuel, except that race fuel cost 4-5 times as much! also burning temperatures is much cooler, so there is less chance the engine will blowup almost every engine can run E85 with a few modifications, but to get more power out of it the engine needs to be built to use E85.. except turbo engines.. I'm gonna run about 13:1 in compression ratio to maximize torque the advantage of using E85 on a turbo engine is that you can run much higher boost pressure with no added risk of blowup I don't know how much more power the fuel will give me, but if I'm getting 1 or 2 hp and it cost me nothing, that's good enough for me Quote Link to comment Share on other sites More sharing options...
David[RL] Posted January 18, 2008 Author Report Share Posted January 18, 2008 new update: removing as much weight as possible radiator will be moved to the rear, and hopefully I will get some aluminium lines for water that's possible to bend without cracking Quote Link to comment Share on other sites More sharing options...
Teddy Posted January 19, 2008 Report Share Posted January 19, 2008 hahah wow, thats ALOT of weight thats been removed. Bleeding the system of air in that setup (radiator to rear) is going to be a royal BITCH. lovin the pics, as per usual :D Quote Link to comment Share on other sites More sharing options...
Medicine_Man Posted January 19, 2008 Report Share Posted January 19, 2008 What is with moving the radiator out of the front? Quote Link to comment Share on other sites More sharing options...
David[RL] Posted January 19, 2008 Author Report Share Posted January 19, 2008 radiator with water weights approx 14kg I'm doing it to get better weight balance Quote Link to comment Share on other sites More sharing options...

David[RL] Posted January 22, 2008 Author Report Share Posted January 22, 2008 (edited) yeah, but it's winter here now, so I couldn't use it anyway at the moment I'm seriously thinking about doing something to the aerodynamics if anyone have heard about the old lotus formula 1 cars in 1978-1980 era also the caparral 2J "vacuum cleaner" from 1970 :2thumbs: this car for an example used a large fan to create a vacuum under the car, to suck it down.. that resulted in much higher cornering speed, and got banned because the other cars behind got much dirt thrown at them even 1 driver got blind on 1 eye because of this car it's possible to create the same effect without fans, by using skirts that seals the side of the car, the skirts must be in contact of the road and some sort of rubber could be used also by adding a extremely low front spoiler, and shaping the underside of the car and adding a rear diffuser you can create a venturi effect that results in higher cornering speeds in 1979 they managed to get cornering speeds up to 5G, that's the exact same they do today, 30 years later, and now they got much better suspension and tires than they had 30 years ago!! I don't know how great this will work on a ke70.. but I think it's worth a try? :hmm: read this for more information on the ground effect http://en.wikipedia.org/wiki/Ground_effect_in_cars Edited January 22, 2008 by David Quote Link to comment Share on other sites More sharing options...
7shades Posted January 22, 2008 Report Share Posted January 22, 2008 I remember seeing something on this topic not long ago, and its something I'd been meaning to try when I had an R32 Skyline as they tend to get a bit 'floaty' at high speed... Apparently adding a few rows of upside down 'speed bumps' on the underside of the car generates lower pressure... I might see if I can find the article again or draw a little picture from memory.

Taz_Rx Posted January 23, 2008 Report Share Posted January 23, 2008 Well there you go....I always wondered what those fans were for on the back of the chapparal. I just assumed they might have been thermos or something. Here's a few pics of the 2J for people who have never seen it,....although most would have on GT4. :thumbsup: This shot clearly shows the ground effects skirt... Couple of good shots showing the "vacuum cleaner" effect.... http://images.google.com.au/imgres?imgurl=...l%3Den%26sa%3DX Quote Link to comment Share on other sites More sharing options...
