1st column is HP at rear wheels.

2nd column is HP at crank with 17% drivetrain loss.

3rd column is HP at crank with 20% drivetrain loss.

 

4th column is HP at rear wheels.

5th column is HP at crank with 17% drivetrain loss.

6th column is HP at crank with 20% drivetrain loss.

 

7th column is HP at rear wheels.

8th column is HP at crank with 17% drivetrain loss.

9th column is HP at crank with 20% drivetrain loss.

 

I tried to post it again from an Excel spreadsheet and it didn't format right once again. It's just a simple calculation anyway of whatever the HP is, divided by 0.83 for 17% loss, and by 0.80 for 20% loss.

So a certain someone running 1050rwhp would equal very close to 1300hp!

 

 

I hope you're running a single rolling pin of rubber at the rear, because you've got a shit-ton of power.

Its not me! Atleast not yet! According to them, they can lay all the power down no problems in 2nd gear.

Man this car is like a NASA rocket or something, you look at the numbers and wonder how on Earth the vehicle will function without tearing itself apart...

 

If the G-car can handle this level of boost through the AWD setup it really was engineered at a whole other level.

5000+ hard miles at 900rwhp+, now aprrox 1500 miles at 1050rwhp... no probs, and its on stock 04 halfshafts.

I don't know if it's related in any way, but Audi's torsen quattros are known to handle 3-4 times stock power without any issues, they are really "over-engineered".

 

But is the G AWD any different than the Murcie's one?

any weight figures on Ripper's car?

I would imagine it weighs around the same as mine, as it is an 04 with glassbonnet and Callistos.

Maybe I have been lucky with the shafts or maybe they are stronger than we all think..

 

Dunno...

 

No problems though... Only problem I have is finding more time to pilot the car :)

It should Allan

 

I will scale it at some point before I decide to add some of the weight saving goodies

you are adding..

if so good build !

As far as I know cars have to programs, pump gas and race gas... each of those programs chooses max boost for that application, no boost control.

Race gas and full boost ..

 

It is more linear in the power application than one would think.

 

I will be installing a progressive boost control at some point.

 

 

Wheel spin hasn't been an issue with my set-up and tire selection.

 

More Power is on the way !!!!!

Thank you! It actually makes sense now.

 

Those are some impressive numbers for sure
