I wasn't sure where to put this. I think this is more than just a rumour. It is to be called LV3. It will definitely have aluminum heads, and likely cast iron block. I'd love to see a 60° V, but it will likely be 90° with a balance shaft. I'm guessing it will have 280+ hp and 275 lb-ft...

Any word on new forum sections for the 2011 Regal?

Eatons are really low efficiency - 55%. the m90 is good for 400 bhp, while the m112 is good for about 450 hp. they are designed to run at 12,500 rpm, so changing to a smaller pulley makes them even less efficient. this means that they heat the air more, requiring the added weight and...

has anyone used the chevy 90° v6 for a turbo project? it has 18° valves, 2.15" x 1.625", 215 cc ports. ryan falconer successfully used a 3.4L version in the corvette gtp - a 1200 hp endurance racer. it was the highest specific output engine of its time. it's cheaper to build than stage 2...

i've learned how to read compressor maps...calculate volumetric flow for your engine, then plot it at a specific pressure ratio. (it actually follows a curve). what about turbine maps? how do i chose an a/r for my app? can i predict where boost will start, or full boost comes on?

The general idea is an LS based V6, sharing 75% of its parts with the V8. Cast iron block engines would weigh 370 lb, and all aluminum versions come in under 300 lb. There'd be a 3.6L with 240 hp, and a 4.6L (282 cu.in) with 280-300 hp. They'd have sinter forged powdered metal connecting...

i have a 1999 buick regal gs. 240 hp supercharged stock. my goal is 500 whp with turbo (no s/c). i will be porting the heads and installing a 206/206 112° cam. buicks make tons of torque down low, but hit a brick wall too early. one tuner has a turbo kit that makes 438 wtq, and 296 whp at 3500...
