JMortensen Posted September 26, 2008 Share Posted September 26, 2008 Jon - you need to bite the bullet and get one for yourself. A scale? A car that actually runs? A V8? I need all of the above! Been looking at XP and running the 5.3L. Weight would be 2350 lbs, so it might take some ballast. Quote Link to comment Share on other sites More sharing options...

You know while your at it ... So what year is the maiden voyage planned for and what exactly is XP? We had a guy in a late model mustand with NO body panels run XP. His car is a work in progress so I'm not sure he was legal but its funny watching someone drive a sedan without doors. Cameron Quote Link to comment Share on other sites More sharing options...

You know while your at it ... Got 15 x 12s for the rear. Plan is to stretch some bubble flares to fit. You know, while I'm at it. So what year is the maiden voyage planned for and what exactly is XP? We had a guy in a late model mustand with NO body panels run XP. His car is a work in progress so I'm not sure he was legal but its funny watching someone drive a sedan without doors. Car should be running by 2025 at the very latest. I'll be 50 then so I'm just hoping my reflexes will keep up. X Prepared is a kind of open prepared class, I think it swallowed up B Prepared. It's in the SCCA rulebook if you want the specifics. The short version is that weight is tied to displacement. With a 5.3 LS engine the weight spec would be 2350 lbs. I think there is a serious advantage to smaller displacement turbo cars because they can weigh A LOT less, but I'm not out for a national championship, I just want to build a really fast Z car.

heavy85 Posted October 7, 2008 Share Posted October 7, 2008 Finally got a chance to scale it at a track day this weekend. 2347 w/ passenger seat which I dont normally run (late mode RX7 leather 35 lb). Maybe 5 gallon of gas give or take. Surprised it was a bit nose heavy but cross was right on. Also heavy to the left. I'm surprised it came in that heavy. PS: Still need brakes ... spun off the end of turn one again ... on a different track. Cameron Quote Link to comment Share on other sites More sharing options...
JMortensen Posted October 7, 2008 Share Posted October 7, 2008 What were the weights? Quote Link to comment Share on other sites More sharing options...
Silver Mine Motors Posted October 7, 2008 Share Posted October 7, 2008 I weighed my daily driver about a week ago and it came in at 2900 pounds. It has a completely full interior, stock engine, 16x7 Riken wheels, and a small 10” sub woofer. Just though I would share. It came out to be much heavier than I though it would.

In case you dont want to get out your calculators that's 51.7% front and 51.5% left & within 1/2% of 50% cross w/ driver. Cameron Quote Link to comment Share on other sites More sharing options...

RaDeuX Posted November 28, 2008 Share Posted November 28, 2008 1975 280Z L28, 14x7" turbines, triple carbs, no bumpers, otherwise stock: 2560lbs Am I reading this wrong? If a stock 280Z is 2800lbs, how the hell does it become 2560lbs just from removing the bumpers??? Quote Link to comment Share on other sites More sharing options...
rudypoochris Posted November 28, 2008 Share Posted November 28, 2008 If I remember correctly the early 280z's were lighter, probably similar in weight to the 260z's. The later 280z's eventually ended upa round 2900lbs with heaviest options, once again if I remember correctly. Gollum and I took his 75 280z on truck scales a while back and weighed his in around 2620lbs IIRC. Put my Explorer which is suppose to curb weight at 4046... weighed in at 4340lbs. When I went on and off the scale it always added 160lbs (I weigh 150lbs, but the scale reads out to the +/- 20). Scale always returned to zero, with just me on it the scale read 160lbs as well. So it was relatively accurate and thus I believe it its readings +/- 40-50lbs if anything reading heavier than actual. Quote Link to comment Share on other sites More sharing options...
johnc Posted November 28, 2008 Share Posted November 28, 2008 If a stock 280Z is 2800lbs, Nissan never made stock 280Z that weighed 2,800lbs. Not even the automatic 2 + 2s. Quote Link to comment Share on other sites More sharing options...
Gollum Posted December 4, 2008 Share Posted December 4, 2008 Nissan never made stock 280Z that weighed 2,800lbs. Not even the automatic 2 + 2s. Obviously JohnC is much more "the authority" on this topic than I am, but I can say that in my hands on experience I can't see a 280Z from the showroom ever being anything close to 2900 pounds. So I can easily see JohnC statement being 100% accurate. But really, those bumpers ARE heavy though. The bumpers and the doors are the largest chunk of weight difference between the 240Z and the 280Z. The bumpers on the S130 were pretty freakin' heavy as well. And the S130 2+2 doors in full trim with glass are monsters. Quote Link to comment Share on other sites More sharing options...
DuoWing Posted December 16, 2008 Share Posted December 16, 2008 I'm curious now. I've been debating on just going the route and building my 76' 280Z 2+2 or trying to sell it and get a 2-seater S30. I saw one person weighed their 76' I believe on one of these pages and it came out 2850 lbs. I'd like to know what it weighs when you drop the bumpers and the A/C. As far as I can tell it looks like the 2+2's really didn't weigh that much more than the 2-seaters in full stock form? Quote Link to comment Share on other sites More sharing options...
Bigdeezs Posted December 18, 2008 Share Posted December 18, 2008 2530 lbs...1975 280Z with LS1/T56 using JCI parts, 4-5 gallons of gas, no carpeting, no spare/jack, no ac or related items, still has heat, 14" aluminum rims. Quote Link to comment Share on other sites More sharing options...
