As fast as a Pagani Zonda and Ferrari F40, I'll put up the VBOX proof later

Pete, out of inane curiousity.... what is the highest peak g-force you've managed to log or come across on 'street' tyres? .72 looks pretty good.

i have had cars pull over 1G of accelleration (around 1-1.15G actually)on the street on street tyres,all have been evo's or wrx's or sti's though,i have had my rx7 as hi as 0.95G on the street,and some other cars in the hi 0.8's,all rwd and in the 12 sec bracket.that should give u an idea

i can garauntee the peak g reading u get on the v box will be in first gear,unless ur getting heavy wheelspin,but i doubt it,adn a low 13sec car will not pull 0.72G in second gear thats for sure.

my 1150kg rx7 with 360rwhp and toyo proxes tyres does just over 0.8G in second gear,thats zero wheelpsin and all power,and about 0.65G in 3rd,to give u an idea again,thats harder than most cars pull in first,and im in 3rd

also,u need a G graph,as peak doesnt give u a true idea,if u have huge grip and no power,u can give a huge dump and create a massive g froce spike on launch but it may only last an instant,then falls away to the normal g force.

Please tell me what G you have @ exactly 130kph in 3rd gear when doing a pull from 100 to 160kph *no gear change shunts*.... If you can tell me any G between revs of 6600rpm to 8000rpm in 3rd gear, but preferably at the above road speed to compare and apple to an apple
I tested a car today on road tires 235's that did a honest 0.657G :bow: which is 35% more G than a Pagani Zonda !!!!! which is at its power peak at that speed.
This car 11.4% wheel slip (so near perfect traction capacity) @ 24psi gauge boost pressure 2.6bar absolute pressure *948kpa and 35 deg C! test conditions*.Pump fuel and my WATER INJECTION

The car I tested has 260% more acceleration force than a Spirit R type A @ 130kph which in its own right is not a slow car :laugh:

**110kph to 144kph** (all listed in one gear with no changes involved)
1.55 sec in 54 meters
^ test car
1.83 sec in 65 meters
^ Pagani Zonda
2.42 sec in 86 meters
^ F360 Ferrari
2.91 sec in 103 meters
^ 230rwkw Spirit R Type A

RICESP is 1.84 seconds in 65.38 meters
*Pagani Zonda its test is slighly down hill so I will call myself just as fast! probably faster, have more top end G *acceleration* where as it's Mazzive 6+lt N/A V12 has a superior spread of power*. (It traps 128mph in 400m test) we both do similar 0-100kmh times for what its worth (within 0.1 seconds). I'll update with a full test when time permits

along with overlays between the two cars

EDIT (additional info, back up of first result)
17th Dec 2010 TESTS RICESP is 1.82 seconds in 64.53 meters *From Aerodrome test* SO ITS *officially* FASTER THAN A ZONDA !
