lq4 build I have a lq4 with 434 rwhpand 396 rwtq. The setup is somewhat basic. It has a g5x3cam, ported 241's, a ls6 intake, longtubes with a magnaflow. THe car is a m6 with a moser 9 and 3.90 gears. Not bad for having about 9.9 to 1 comp. ratio.
I have looked at some other cars with this cam and seen smaller numbers. I was wondering how much the cubes have to do with it? And how much The lower comp. is making a diff?
My goal with this setup is to get to the 475rwhp. I just ordered a fast 92 and thinking about an elec. water pump, and upgrading to a 3 inch cutout.
The run is with the 2 1/2 in. cutout closed.

That good for LQ4. I have LQ4's comp ratio ~~9.0 to 1. I hope so, it was +10 to 1. Oh well.Did you change the crankshaft or connecting rods? Same pistions?
I just look around for LQ4 dyno. My goal for my LQ4 run ~+430-450 hp.
Keep-up :Thumb-Up: let me know if you upgrade.
