zafeniak Member 8 Member For: 17y 5m 29d Posted 01/02/17 02:51 AM Share Posted 01/02/17 02:51 AM Hi Guys- I currently have a 2012 FPV GS Mk11 with a tune and CAI, pushing out 367wkw. It's been great so far and I am looking at stage 4 upgrade packages (intercooler, smaller pulley, high flow cat, larger injectors and fuel pump). These packages seem to be going for around $12-$13k and as I understand the expected power output would be around 450rwkw. Now before I dive in an go ahead, I was wondering if it would be more cost effective to sell my car, by an F6 and invest $13k in to that. I understand that the max power output would be less with the F6, but comparing a few dyno graphs, I can generally see that the torque from 2500rpm --> 4800rpm on the F6 is significantly more than the GS. After that the torque curve on the F6 really drops off, where as the GS is linear right up until 6200rpm. Now with this being said, what would be a quicker car down the qtr mile; GS with the stage 4 package pushing ~450rwkw, or an F6 with $12k invested in it (pushing somewhere around 360-370rwkw I imagine??) Advice would be greatly appreciated! Link to comment Share on other sites More sharing options...

The supercharged 5L will run similar times to a turbo 4L (assuming same ZF gearbox) that has about ~70kW less than it. The F6 will feel faster, though, due to the way that the torque is delivered for the F6. You could make a tidy profit by selling your car and modifying an F6. You will sacrifice sound quality (in terms of exhaust) for the F6, though. Link to comment Share on other sites More sharing options...

Cooler, valve springs and zorst are the biggest investment. Though if u start going for +500rw then fuel system will start costing. Plenty of barras pushing 450rwkw with 200,000km on em. Strong engines mate. Edited 01/02/17 04:47 AM by BAXRTUTE Link to comment Share on other sites More sharing options...
