Am doing a sheet to go in my car window as am on a Lotus stand at an airshow this week and don't want to spend the day explaining what it is and what it does so am doing a info sheet to go in the window. I dont want to put any daft willy waggling figures so wondered what is generally considered the rough 0-60 or 0-100 time and top speed, so the kids don't keep asking me that one as well. Its a stage 2 SC car with 255bhp and about 220 lb torque. Suspension sorted on 888's etc etc. I was thinking 0-60 around 4 seconds ish, 0-100 11 seconds, 150 top end? Car revs out at 6800 I know this is a naff thing to ask so flame away. Martin S

You have a PM

What have you started here, Martin?..........

[rob999]

Just say it's quicker to spin it then get to 60.

[Goosenka]

Just make it up.  Who gives a sh*t anyway.

I have done a timed 0-60 in 3.8 seconds. Stage 3 turbo approx 270 Bhp on standard bridgies.

 

your timing gear is inaccurate then. 

 

i did a couple runs with the perf box 

 

0-60 = 3.9

0-100 = 9.5 (that was with the spolier tho)

 

 

Chris, not sure how you can say that.  Every single car/driver combo will perform differently.  The equipment in both instances may be correct or incorrect, but it's kind of irrelevant given that 2 drivers in the same car with the same equipment may post substantially different times.  As a rough guide looking at what people have said, drop 0.2 seconds per stage of tune on the Tub.  The SC ones though?  Who knows.  0-60 probably similar but I expect they lose out on 0-100...

 

 

well one major factor is that im using semi slick tyres where bob isnt. thats how i can say its out.

0-60: sufficient

0-100: Untested

Top speed: In excess of 70mph

[turbobob]

Mmmm. Possibly. It is mainly about traction at that level of tune in 1st gear. But less of an issue in second. If you nail it well in first and just hold the traction then why not? I bet if you did a few more timed runs you could improve that time.

[turbobob]

I thought the top speed would be limited to the gearing not the ECU ? 

You can increase your rev limiter limit in the ecu which should increase your top speed providing your have the power / torque to get there.

just stick this thread on your windscreen

There is a vss limiter in there too iirc.

Is this by passable? Iirc there are a few vx's that have had their rev limits increased.

[siztenboots]

yes it can be changed

[Sutol]

I've still got the old sheet you did for me before in the car Martin.

Though if yo uwant to do a proper timed 0-60mph run, then you'd have to be comfortable coming out the otherside without a gearbox still attached. Different drivers, different techniques, different times.

If you're going to dump the clutch at max revs then you'll just light the wheels up.

No one said about simply dumping the clutch at max revs, that doesn't work for any car.

 

But to get a proper set of figures on a car you'd need to do multiple launches to ascertain where the best level of grip and acceleration is, and just how much to either sidestep or slip the clutch on take off - as well as where to change gear. Talking of which, you'd need to flat shift (keep the accelerator pinned) as you do swap cogs, and pay no attention to the noises as you do so. Brutal...

 I won't be buying an ex-press car anytime soon, then.

[MartinS]

Sorry to have started this! Went for 0-60 4.0 Top speed 150 Power 255 Torque 220 Lb Weight 900kg. That'll hopefully be enough to shut little Tommy up and his nerdy engine obsessed dad. Martin

I have done a timed 0-60 in 3.8 seconds. Stage 3 turbo approx 270 Bhp on standard bridgies.

Timed with what, using what as the indicator for speed?

timed with a sundial , its an NA
indicator of speed, people walking past overtaking , its an NA

timed with an atomic clock , its a turbo
indicator of speed, low flying tornado's waving you on , its an turbo

Brilliant

This is a vbox graph of two runs, with regular ku39 tyres and a bad driver being sympathetic on the car. stage 4.

All of which is why "in the real world" acceleration times from stationary are almost meaningless for the vast majority of cars bought, and why in-gear times are far more representative of how quick a car actually is..

 

Its the same to me as comparing max. BHP to the actual engine power / torque through the RPM range - those few extra horsepowers at 7k rpm are virtually useless in most scenarios. Both factors sell cars though.
