I wonder if the BTR rotor mods change how the overall blower responds to porting, or if that is already factored into their testing.

The problem with the 3.0 comparisons is that they are...

Magnuson saw some gains in the same case but struggled with longevity at higher RPM's to where the small gains they had didn't warrant the extra risk for those that will inevitably overspin it.

Sure thing. Another important point is that we proactively swap transmissions if something seems off, or to just have it inspected to see how frictions, steels, etc. are aging. I keep a spare for...

I can only speak for how I use the car, which is drag racing, but I can confirm the valve body wasn't the limiting factor for achieving our goals. That said, I recommend a new valve body for a 10L90...

Hate to hear that. Word of mouth is critical in this industry and those that don't realize that likely won't last long, or certainly not be as successful as they could. Hopefully you'll have fewer...

Yep. It can be hard to swallow that initial investment, but more times than not, people are better off in the long run choosing a shop with a proven record of satisfaction. If I were looking for a...

We use the blue cap for my 10L90. It was recommended by Pure Drivetrain Solutions a few years ago.

Makes sense. I’d expect 60-80 WHP from porting the 2650 at that RPM assuming the engine was efficient and boost stayed relatively low.

I’ve seen 19,xxx on a 6th gen. Haven’t paid much attention to pulley combos on the others. I’ve just been watching the ET’s and all the low-8 to high-7 blower only combos elsewhere are the 3.8.

The 3.8 I’d be interested in. I’m convinced that is what it’ll take to beat an all out ported 2650. I just don’t think you’ll be able to safely spin the 3.0 to get there so the extra displacement at...

I didn’t have problems with my 2.9 either, but it was out of breath in the low-900’s. Perhaps some issues were due to install/use, but I’ve seen more failures reported on the 3.0 than I have on the...

Whipple is more interested in Ford and Dodge and slept on the LT’s to where they are way behind on this platform. The 2.9 for LT’s also left a really bad taste in the mouth of many shop owners due to...

As mentioned above, you need the power to make 2nd gear quicker, but if you do that with a PD blower, you don’t need to change the converter. Centri or turbos, yes.

I agree with this. An occasional street race or pull is a different load than 8-9 seconds (depending on quick your car is) of sustained load several times at a drag strip outing. I got about 50...

VSS is just vehicle speed. I’d be surprised if you aren’t loogging it, but definitely add it if not. Here is a pic of a log from a couple years ago. Red is RPM and green is VSS. It was very rough up...

For how you use the car and your power level, yes. Better to get ahead of issues versus having them start at a track rental or event and wasting the outing.
