TheNeedForZ Posted September 30, 2004 Share Posted September 30, 2004 Hello, I've been searching for some 0-60mph times of various cars/motors on this site. For example, a fellow on this board says : "My 383ci Chevy 240Z does 0-60 in 5.5 secs" And then I compare this value to various car specs in car magazines, for example : Honda S2000 does 0-60 in 5.5 secs Here's what I don't understand 383 ci 240Z : 2500lb/350hp HondaS2000 : 2800lb/240hp Clearly the V8 Z has less lb/hp than S2k, but why do they have the same 0-60 time?

KraZeeZX Posted October 1, 2004 Share Posted October 1, 2004 Ok... a few reasons: a) The s2000 5.5 0-60 time was established by professional drivers. Everyone here figures out their 0-60 times on their own, so.... the 5.5 s2000 time is maxed out and official while the hybrid Z times are most likely lower than they could be and definately unofficial. 1st gear traction - how many guys here do you think get traction with all of that v8 torque??? I'd say... 5% max. It's easy for a 4 cyl car with some fairly wide(for an import) tires to hook up and speed away... not much torque under the s2000 hood either. c) redline - v8s have fairly low redlines... meaning earlier shifts which disrupts your run to 60mph. The s2000 has a 9000rpm redline (if I remember correctly) making it easier for them to get going in only 1 gear and then shifting without much loss in momentum. d) 2nd gear traction - same thing... how many s2000's can lose traction while shifting into 2nd gear??? none! I'd say almost all of our hybrids would break traction twice while trying to get to 60mph. Now.. get a 2800 lb HybridZ with your 350hp/350tq, put some FAT tires on there, some limited slip... give it an AWESOME driver, hope your CV shafts don't break and see what your 0-60 time is. It will be FAST! It's all relative... the s2000 is a factory car, it should be set up to get a decent number. If you took our cars and gave em enough traction to compensate for the power... you'd have one heck of a low time. I'm hoping to be close to 5.0 seconds when I get out and drive mine. Some midly fat & sticky 265's on all 4-corners should help me get there... I just hope I can drive it well enough! -Vann Quote Link to comment Share on other sites More sharing options...
blueovalz Posted October 1, 2004 Share Posted October 1, 2004 Good breakdown on the variables. My "low torque" 289 in my Z (2470 lbs w/driver) provides a 0-60 time (averaged over 3 runs) of 4.2 seconds with a 7500 rpm shift using 4:11 gearing. Very slight spin up front (again, this motor is not a stump puller), and none on the 1-2 shift with a peak torque around 4900 rpm. I've driven the S2000 and it has a nice constant smooth pull over a long rpm range, but it's got nothing for a V8 Z. Quote Link to comment Share on other sites More sharing options...

What size tires do you run on the back of that bad boy? -Vann Quote Link to comment Share on other sites More sharing options...
80LS1T Posted October 1, 2004 Share Posted October 1, 2004 According to my GTech Pro Comp, my 3000lbs 280ZX(guesstiment?) goes 0-60mph in about 4.5 seconds. Thats with 225/45/17's street tires. Now I would imagine if I had some nice sticky tires it would drop down a good amount since I wouldnt have to baby it out of the "hole". But traction is deffinetly a major factor for V8 Z's. Guess what even if the S2000 had a 0-60 in 3secs and the V8 Z with 350HP/350TQ had a 0-60 in 5 seconds it wont be long before the Z is blowing past that S2000 like the wind!

I'm willing to bet if the s2000 got to 60 in 3, a 350hp Z would never catch up, provided the holeshot is the worst disadvantage for low displacement OHC engines...at least compared to proven pushrod engines. Off the line its all about a low RPM peak torque (like someone said, stump puller)...but once you're off the line, you need a wide powerband that doesn't fall off until redline (in a perfect world...or a top fueler ...that's why they only have one gear!). I'm considering a hybrid engine for my SBC chevy...I know all the Chevy gurus know how Chevy can make (made) a better 302 than Ford (not downing the Ford 5.0's in the least). The '69 DZ engine configuration will cater to my driving habits a little better...with a 327 block and 283 crank, the torque will peak a bit higher in the RPM range allowing for less difficulty spinning off the line, and I should hope to push that engine to 7500 RPM no problem...as well, it will pull hard all the way to redline unlike the average larger displacement engines without specific tuning/work/parts etc. Since I come from both sides ('90 camaro 305 TBI turd and '93 honda civic ex) I think this is the combo for me...great 0-60's too! 8) Quote Link to comment Share on other sites More sharing options...
