Hi all,

Just curious, been trying to research this a bit recently. I know lots of people claim torque figures based on running race fuel or E85 especially when trying to determine the maximum power and torque output of their build/engines but I am wondering what is the maximum torque output achieved on a 3.8 engine running on v-power, the stock turbo's on a stage 4 setup actually seem to produce pretty respectable torque figures on vpower it seems.

650ft lbs on vpower stock turbos and equivalent to stage 4 here.

Simon Chorltons SVM built car was impressive, Ryan had it a couple of days while mapping, that was 100% on Vpower as I watched him fill it up, that made 970bhp and 990ftlb at SRR.

Was that on a 3.8 engine Jamie? What turbo's was he running? That is incredible.

Christ.....990ftlb.....I bet that felt slow:runaway:

What sort of transmission upgrades can handle that?!

I just had to check his build thread, sorry mate, that was a 4.0L he had GTX 3076's

Depends how brave you are, mine runs 840ftlb on the stock gears, stock clutch but with two extra plates.

Hmmm is your torque at the hubs on v-power Jamie? That's impressive. From what I see on the gtrlife forums it seems that around 680lbft is what they get on the ams alpha 10's on 93 fuel.

SRR figures are converted to an estimated crank figure mate.

I had 12% showing on the ethanol gauge when I did that run, straight vpower is about 7% ethanol.

 

[splking]

I guess thats similar to ~700 on straight v power at the hubs then. What boost are you running on v-power only now Jamie? 1.8bar?

[JamieP]

It runs 2 bar all the time, no matter what fuel is in it.

990, i bet that was a tease, 10ftlb off 1000 :sadwavey:
