whats a good quarter mile time / terminal for a rwd sapph running circa 500bhp?

I know its vague LOL

 

Unless set up for drag racing, slower than a 385bhp car, as it has too much power compared to traction combined with a very agressive power delivery which makes modulation of traction tricky, as power / torque can almost double in 500rpm .

Should pull good terminals, but not very good ETs.

If it has REALLY good traction as well (due to being set up for the quarter with drag tyres / decent rear beam and geometry) then expect high 11s / low 12s @ 120-125mph.

 

what you trying to say there mike

btw i knwo what modulation means when talking about frequancys

 

That getting a perfect launch is VERY difficult, the engine either bogs or lights the tires up. Getting that happy medium of the tires being on the verge of breaking traction and still keeping the turbo spooled up is almost impossible without the kind of trick rear-end DannyB had on his car and / or without drag radials.

 

it was mike's calender word for today, a la Alfie

 

You are "modulating" the throttle peddle to compensate for the lack of traction...

"the act of modifying or adjusting according to due measure and proportion"

 

sorry mike just using the word modulation in that sentance didnt make sence too me,,,,, but i do totally agree with what you are saying

 

Only because you understand modulation in the form of wave carriers, whereas in can be used to describe lots of other "adjustments" .

 

ya mike,,,, sorry im really bad with words,,, i was the only person in wales not too sit a english GCSE (i shouldnt really be proud of that )

 

I saw one last year run a low to mid 11 at 130+ mph, was on road tires and rwd, 533bhp, went for a ride in it on the road and sh*t my pants,
however it was sideways nearly the whole way up there, monstrous

 

Mine did 12.1 @ 127mph so Mike aint far out.
