Title: 1/4 mile 12a
Post by: Steve-M on April 03, 2010, 09:26:27 PM
Has anyone run 12a power down the 1/4 mile?

I am thinking of doing a few RWYB with mine, looking to then strip and lighten things until the engine loses interest, I am not bothered if it takes me 1 episode of Emmerdale to do the first run, more of a tightwads experiment where a starting point/ goal would be good!
Cheers,
Steve

I had a 79 series 1 that the previous owner did quarter miles in,i\'ll see if i can find the times/mph he did it in with the 12a engine,car was not lightened up,but had sports exhaust & mechanical secondaries on nikki carb.[engine had 124000 miles on it when he belted down the strip]

My old rx was a 85 series 3 did a 16.0 sec @ 89mph with lots of wheel spin of the line.
I just had a sports exhaust and made 109@wheels and 140@fly.

Yes it was. However I may have had a 600kg weight advantage there. still the same amount of grip as you. However things are a changing in the engine department. self built now. It will either go bang or go like stink lol
