280zwitha383 Posted October 29, 2005 Share Posted October 29, 2005 Last night for the first time in my life I went to a track and I had a blast. "The Piece" as my car is so affectionately named ran a best 1/8th mile at 8.23&88mph. My first two runs were horrible, I didn't spin all the water off of the tires I guess and I ran two mid 9's. After looking at everyone else 60' times in the timeslips database, I realize that I'm losing a lot of time here also because my best was 2.0040 and my average is somewhere around 2.3. I'm still running some little 195/70/14 walmart tires in the back so hopefully that's a lot of it. Everyone says I was peeling most of the track which was fine. I didn't want to get any bigger tires my first time so I wouldn't have to worry so much about breaking anything. All but one of my runs I had a passenger and all of them I had my spare tire and rather large speaker box in the back. I thought that I should have been in the 90mph range and most of my runs I came in at 86mph. Anyway, does an 1/8th in 8.23 and 88mph sound right for an engine with maybe 450hp/450tq on stock tires and suspension in a 280zx? Any ideas what I could expect with some better tires? One thing I do know is that my timing was somewhere around 50* total advance and I tried unhooking the vacuum advance but it didn't really help my times. I'm not familiar at all with times and mph so any advice would be great. Thanks. Quote Link to comment Share on other sites More sharing options...
jbc3 Posted October 30, 2005 Share Posted October 30, 2005 Those tires are killing your times. (and adding a passenger didn't help much either) 450HP with decent tires and a decent launch you should be in the mid 7's. But for your first time out, it wasn't bad.

mas28O Posted October 30, 2005 Share Posted October 30, 2005 When I was making 400rwhp my car would run 7.1@99mph. 1/8 Quote Link to comment Share on other sites More sharing options...
dr_hunt Posted October 30, 2005 Share Posted October 30, 2005 We're making 450rwhp and the 1/8th time is 6.70 and over 100mph, so I'm just guessing, but either your not making that kind of power or there's still WALMART smoke at the track.

Guest bastaad525 Posted October 30, 2005 Share Posted October 30, 2005 I know your pain dude I run the exact same size crappy tires on stock ZX wheels... dynoed 303 ftlbs of torque to the wheels at 3000rpm... lots of fun trying to put that down thru crappy $25 195 width all season radials, with an open LSD to boot! Havent been to the track but I did try a Gtech pro SS, magazines have shown them being pretty accurate... I was averaging 2.5 - 2.7 second 60' times, spinning the tire so bad I get nearly sideways. Fun - yes Fast - no! Quote Link to comment Share on other sites More sharing options...
280zwitha383 Posted October 30, 2005 Author Share Posted October 30, 2005 yeah, I got sideways halfway down the track a few times. The stupid fee to run your car at the track is $20!!! Which is why I might not be going out there again anytime soon. Maybe once I get some better tires and my timing fixed and maybe they go down on the price I'll go out there again and see what it does. I guess as long as people pay that much they'll keep charging. This town is full of rich people and it's a brand new track so I won't keep my fingers crossed. Quote Link to comment Share on other sites More sharing options...
Guest bastaad525 Posted October 30, 2005 Share Posted October 30, 2005 that sucks... $20 for a 1/8th mile track??? 1/4 mile tracks around here are $10-15. But yeah... you gotta pay to play. It sucks around here because there are so many guys who think they're fast littering up the track so it's usually pretty crowded and you're lucky to get 3-4 runs in. About the traction... it is kinda silly to even attempt running that much power thru 195's... but I'm trying to keep that sleeper look. My wheels are stock 280zx wheels, totally fit with the whole sleeper purpose of the thing. If I throw some fatty wheels and tires on there people might know somethings up Quote Link to comment Share on other sites More sharing options...

On the turbo rims you can run 235/60 bfgoodrich drag radials. Quote Link to comment Share on other sites More sharing options...

Guest bastaad525 Posted October 30, 2005 Share Posted October 30, 2005 Bastaad: open LSD.....isn't that kind of an oxymoron? JT oops Thumper - yeah I know I coulda fit 215's on there but when I bought them I REALLY BADLY needed tires the other ones were showing cords, and I was VERY broke. For whatever reason the 195's were on sale for like $25 each, I actually had wanted 205's because that's what I had originally and had always had on my ZX, but they were at least $20 more, each, if I remember right. But yeah... if I end up never getting a buyer for my car, I'm going to put 215's on there soon, the 195's are just about at the end of their run. Not gonna put anything sticky on there though, just the cheapest, longest wear rated, all season radials I can get. I don't race enough for traction to really matter that much.

dr_hunt Posted October 30, 2005 Share Posted October 30, 2005 I got tired of the tire ripoff, finally got myself a dealer account, I bought a set of four 205/75/15's for $132 out the door. My 11-24.5 truck tires are $200 vs. $300-$400 elsewhere, My big equipment tires are $500 compared to $1000-$1200. $20 more for 205's over 195's simply a rip off. I can get General, BFG's, Michelin's, Pirelli's, Continentals, etc. for cost. You guys ought to think about doing the same wherever your at. It's simple, get a business license, go get an account, start saving some $$$ and making a few $$ off your friends, while they save some $$$ too. I got a whole set of 4 195/14's for my moms minivan for $76 out the door. My supplier regularly has sales, 235/75/15 General AS radials, $20 each last months special. Sorry to hijack the thread, just you guys need to know the truth about tires and tire prices. Quote Link to comment Share on other sites More sharing options...
280zwitha383 Posted October 30, 2005 Author Share Posted October 30, 2005 Wouldn't that mean you have to start paying taxes if you were to get a business account? You say start making money off of your friends but the hassle of recording all of that crap and paying taxes doesn't seem worth it to me.

280zwitha383 Posted October 30, 2005 Author Share Posted October 30, 2005 Also, there are a few reasons I run those tires still. The biggest being I am scared of the rearend. I have a different diff. and some 280zxt CV axles and I should really stop being a pony and throw the bigger tires on there and if it breaks then fix it. I'm also kind of tired of throwing money into this thing. I go through thoughts like that and eventually I will get the fever again and get it done but I don't see it happening for atlease a few months. :sigh: Quote Link to comment Share on other sites More sharing options...
Thumper Posted October 30, 2005 Share Posted October 30, 2005 This guy does wheelies and 1.34 60ft times on the stock rear-end. http://forums.hybridz.org/showthread.php?t=105587So it candle the abuse of bigger tires than 195's I personally have put 235/60 drag radials on my r200 with stock halfshafts non-cv axles.

280zwitha383 Posted October 31, 2005 Author Share Posted October 31, 2005 yeah, I've seen some of his posts but I'm not sure exactly what he does. I know they make sure there is little angle in the shafts by putting spacers on top of the struts or something like that. I think that guy should have his brother do a writeup and then someone should sticky it. :hint hint: Quote Link to comment Share on other sites More sharing options...
Gollum Posted October 31, 2005 Share Posted October 31, 2005 Yea, I run 215's on my stock ZX wheels. Grips SO much more than the previous tires (wich had been run flat so the sidewalls were destroyed). Got all 4 put on balanced and alaigned for $205 if I remember correctly. Previous tires could spin 2nd a bit and sometimes get 3rd to chirp a tiny bit. These new ones I can't get to make any noise in 2nd (might have to do with really soft clutch and tranny that doesn't like to shift at high RPM).
