0.5 secs is light and day in a drag race.

 

would getting a high 1.6 or even a low 1.7 make that much difference?

 

Yes, could make almost half a second difference.

 

would lightweight pullies make much difference?

 

You should try and get the most of you current setup as it is now (room for improvement) and then if you still want to go faster, consider a next stage of mods.

Reducing rotational mass makes the car more lively and improves acceleration (the more you take off the better the improvement).

I run one of the lightest flywheels available (makes quite a difference) on my car but haven't got around to doing the pulley yet (not had the time).

 

cheers guys ill most diff get some more practice in.

 

Exactly. I found that time lost in the 60ft was time lost in the ET. There was a direct correlation, for me at least. And that earlier comment about one car being 0.5 seconds slower than another - that's a lifetime in quarter miling! How much do think I wanted a 12.8 in my Clio instead of a 13.3?!

 

That may be true at a dragstrip but if you go on a yellow at the traffic lights you must have a very slow car if it dont move till the lights green,
.....and you cant practice staging at a traffic light....

 

Maybe I should have worded it better, practice launching would do it.

 

Damn right it is, Bob.

What was the spec of your car when you ran 11.7s?
