you were racing on a closed course right?
Can anyone share some insight?
Car kinda had a wonky idle. Sometimes it's high. Sometimes it bounces. My biggest issue is while driving normal and "feathering" the gas to maintain speed it's a little bit unresponsive for like an 1/8th throttle.
36# tune from c2
6puck sprung clutch(not sure if that's even relevant)
Stock Audi a4 diverter valve
I leave for sowo(13.5hr drive) would like to work this out
Only thing that might change this also is the vacuum line on the throttle body is plugged. Not sure if that matters at all.
Not to be a negative nancy or anything, but I find that extremely unlikely from a vfe kit (or any standard V9 kit).
Many here will agree that VFE is pretty shady when it comes to VWs, and they like to stretch their advertising a fair bit.
300hp at the crank perhaps. After drivetrain loss, it'd be about 260-70whp.
edit: their own graph for stage2
looks like 250whp & 230lb-ft, compared to their advertised 280hp 250lb-ft for stage2
add maybe 10whp per psi (their stage3 is 2psi more)
250whp requires more than 10psi. On stock cams its more like 12psi. With 268 cams, 12psi and a good solid tune 300 is a lot closer, however it still is very difficult to go much over the 300 range as the ability of the belt to transfer drive torque is being overloaded at that point.
for over 6psi you need 30# or 36# injectors depending on the software. The 30# C2/UM file sucks the big fat one. If your running 8psi on GIAC, I suggest staying with that. The allowance of power and more boost with C2/UM is at a trade off in driveability and engine life. C2/UM runs way rich and will wash down the cylinder cross hatching.
Only way to go is Lugtronics/other standalone.
<--Have rebuilt way too many SC engines that the wrong software killed.
ruf and me designed a new impeller wing for the rsc charger. it now pushes out 13psi. should be enough for 300hp on a vr6 engine. the main problem will be the cooling with a standard fmic. the pressure drop is to big so we only use liquid intercoolers for supercharged cars. maybe this will help the Vx chargers to more boost.
we tested it on an r32 mk4 with a 9,5:1 compression. it made 370hp. ill post the dyno later
X2I have been looking for pics of a v9 with the outlet rotated foreword to a fmic and have had no luck. If anyone has any please post up!
hmm.. curious! in fact that you have to calc the boost on top of the fuel pressure. so when you run 4bar fuel pressure + 1bar boost... youre already at 5bar fuel pressure. cant imagine what stressy job its for the programmer to get a stable idle on such cars
102octane? we also got e85 gas stations now
