Ahh...well that might do it I guess...
What times/MPH are u hoping for?
At a guess and considering the car was in 100% street trim at a weight of 2010kgs on the scales, I the think up around the 125 - 130mph mark should be achievable.
What do you guys think?
With 490rwkw you should be trapping 130+ easy
666HP at the tyres, hhmmmm and 121mph, something not right.
Put some sticky tyres on and if you cant run a mid 10 with that kind of power
with that weight ! Somethings wrong.
490rwkw! That is awesome for the mods! I think I would be lucky to put down 350rwkw with a HTV2300 albeit Ls2 with stock exhaust.Quote:

Remember guys, this 490rwkw would have been measured on the Tunehouse hub dyno - so no rear tyres are brought into the equation - hard to compare to other "rolling road" chassis dyno's
I hear what you guys are saying... The mph is low but don't forget this is in 100% street trim. Comparing this to the Walkinshaw cars at this years Motor Hot Tuner, the car has done well...
The car will go out with semi-slicks which should be interesting.
How many manual 2 tonne VEs have run in the 11s on 20" rubber?
Doesnt really matter, the MPH tells the story.
I had a look into some of the online Horsepower calculators and here are the results ...
Using:
2010 kg = 4431 pounds
121 MPH Trap speed
The calculators come up with a figure of 612hp to the wheels = 457 rwkw !!
The dyno measured 490 rwkw peak ... that is about a 7% difference, a loss of 33 rwkw.
When you enter 490 rwkw (656rwhp) you get a calculated MPH of 123.5 mph.
That's only 2.5 mph off what was recorded over the quarter.
Maybe stickier tyres might help?
Can someone with some drag racing experience check the above numbers?
