Re: EME's "Dragon Heart" 378 Ultra light ZR1 build!!!!
Good luck on the major diet! I'm going to hope you can weigh stuff and post as it comes out (even though I haven't managed to do that) - great references for the rest of us!
I'll chime in with a data point for you, since I just corner weighted our car. Added weight: R&D Camber Brace bigger front bar reservoir shocks hockey puck style steering rag joint ~Should be the same weight: Front and rear springs quick steering rack FIC injectors K&N filter believe it had 1/2 tank of fuel but my sender is funky driver at ~175lbs Not sure what the difference may be: huge CCWs/Hoosiers (light but maybe not a big difference vs stock) Watson headers & Borla exhaust, were on the car already Blingy aftermarket head unit but I suspect same Bose amps open air filter lid Lower weight: no spare, tray, bag or jack lightweight battery, I think it was 9lbs removed A/C compressor & lines (next up, condenser) removed air pump etc (still have to chase the valves out of the headers) plastic headlights (might have been original but ours came with glass ones) smaller rear bar The bad news is, I wound up at 3500 with me in the seat. The good news is I was able to get within 15lbs cross weight with one turn of the screw. Since S2000s and a couple of Porsches have moved into my class I think I'm going to be a bit overweight. Maybe I can get 125lbs out of it, but... Best, - Jeff

Re: EME's "Dragon Heart" 378 Ultra light ZR1 build!!!!
Hey Jeff,
Great points!, ..Most if not all that stuff is GONE, The MOST difficult thing will be to make it as light as we want and still make it street legal.....Touh to do, But we're working on it with carbon fiber hood, Lexan windows, removed dead weight(interior, spare, stereo, HVAC, AC, ect. So we are on the right track but we are still deep in the planning phase still yet. Also with many of the Big builds of the winter coming up we are taking it slowly. We will weight the care and all removed equipment as soon as we can. As shown earlier, I ported and polished the top end and now moving forward with the heads, liners, ALL FORGED bottom end(minus crank) and doing a lot of mock up for racing equipment(carbon seats, diffuser, cannards ect. Its moving in a lighter direction!

Re: EME's "Dragon Heart" 378 Ultra light ZR1 build!!!!
Apologies for bumping an old thread but I'm curios about how light a track duty zr-1 could get and if this project was abandoned or completed?

I have the ccws that car needs. 315s up front, 335s in back.
Have hoosiers on there now for fitments. I'm going to stick with 18s and just go with R888s and be done with it. Let me know if you want them, we can horse trade.

Re: EME's "Dragon Heart" 378 Ultra light ZR1 build!!!!
I been down the dirty road of adding lightness fun but frustration does hit along with insanity......
Volvo has nice aluminum bumpers that can be cut down drilling out centers of bolts cutting down bolt lengths shorter screws I've even built a hvac heater using a heater core and a 4 wheeler radiator fan with a toggle switch check eBay you can usually find titanium hardware by the bucket cheap Boeing has a floor sweep shop in Seattle if there’s members here willing to go shopping for you if there close....bolts rivets sheets of titanium inconel makes sexy exhaust.... .015 thick and front to rear weighing in at 6 pounds on a single 3 inch....but cheap 3 inch ic piping on eBay makes light exhaust as well but hella loud Harbor freight sells a nice hydraulic hole punch and vendors on eBay have dimple dies made to use the harbor freight conduit sizes...punch is 100 and seems like my dies were like 375 Best of luck it is worth it in the end Just remember there is a point lightness becomes dangerous be safe |
