Power To Weight Ratio?

[FORZA-MOTORSPORT]

Guys last nite after getting my car tunned i went out for a "thrash" now my car only has around 184rwkw running 8psi and it weights at least 1650kg being a gts4 with a 3L rb25/30 in her and all the extra goodies. Now my mate has a falcon BA turbo with 285rwkw running 15psi weighting around 1700kg, how can i pull away from him it doesnt make any sense as he has 100rwkw more the me and only 50kg??? Does torque play a huge factor here but i thought the falcon 4L would be more torquer then the nissan 3L as it has more cubes but it must have something to do with the bore/stroke of the 3L or am i totally off the track??

kerb weight of the falcon would be closer to 1800kg and yours woulds be a bit lighter than 1650 i think... and/or maybe the dyno readings were innacurate.

I also blew off an r32GTR which was pretty stock, believe you me with all that extra stuff that straight 6 3L weights a hell of a lot enough to almost bend the engine stand!

Have a look at the power curve of each car the ba might only do 385rwkw at 6,000-to 6,500 rpm. also does the ba have stock rods and pistons.

It was 285rwkw not 385rwkw , he has blowen 3 gearboxes, it has uprated injectors computer etc, the point im trying to get across is i dont think its just power to weight ratio, torque must play a huge factor!! And i believe after driving my rb25/30 that these motors have a massive amount of torque for there capacity. Well if you dont know my rev limiter is at 5,500 as she leans out after that so i dont even get to use my revs its all torque..

what does pistons and rods have to do with anything?

Diff gears ect could make a difference. The BA's produce mountains of torque very ealrly, think it would be more then the 3 ltr. I had a rb30/25 in my old car and have driven a number of ba turbos as i work for ford and the low down torque and ability to boost down low is muh better then the 3 litre. Standard they use a 1.06 rear housing and can make full boost just over 2 grand

Just because 2 friends have xr6 turbo’s and a mate works at ford on one car the rod let go and he was only running 10psi with a flash box and a cooler, also my other mate only had a exhaust and the same thing happened and ford didn’t weren’t it because he hit the rev limiter a few times and the exhaust, ford can tell when they plunge in there computer.

I think youll find the gearing is quite different between the cars, thats probably the only explanation I can think of.

Ok well my motor must be a freak then...or the driver is possessed

[RB SANDY]

the xr6 turbo has a 2.7 diff ratio also my mates xr6 just had the flash box and the std cooler and it did 245rwkw at 10 psi.

the 2.7:1 is th 6 speed auto diff. the manual i think are 3.45:1
