View Full Version : ms4 and ls6 heads dyno (where is the torque)?

10-27-2008, 09:26 AM
So I hit 430hp and 383tq. The torque seems low. Mods are
ls6 stage 1 heads(tsp)
ms4 cam
pacesetter longtubes
y pipe
slp loudmouth exhuast
ford racing 42#injectors

I am mainly just wondering were to find torque? Should I have gone with a different cam. I here that people make this without my cylinder heads. I feel I wasted money on the ls6 heads when they didn't add like a single hp. Well I am happy with the hp not the torque I was expecting more than that. I am going to install a slp 25% underdrive and putting my exhuast cutouts back on. That might help a little bit. Any input would be great thanks.

Post up the graph so we can see the curves. You have have been victimized by a stingy dyno or bad weather correction. If you can post up the dyno conditions and correction factor, that may shed some more light on the subject. I would have expected higher hp and torque. Those TSP (PRC) heads are better than that.

Something is definately wrong..I have TSP stage 2.5 5.3 heads fast90/90 and (this guy^ cam) 232/238 6xx 6xx 111 and put down 435 rwhp 407 rwt in an A4..

something is extremely wrong. im 458/410 with a 224 and Ls6 heads...

OP, you have an U/D pulley as well? That will help you out some as well. but you should be over 400rwtq by now. A4 or M6...? Gears?
