| But you can get an idea of how the turbos will respond in the real world. First.. look at the torque curve and where it peaks. My stock turbos peak at around 4400-4500. Jeff's PE's peak at around 4600. That right there will tell you that they will "snap" in around the same time once spooled up. Then look at the horsepower figures per RPM. Jeff's car: 3000: 140 hp
3500: 215 hp
4000: 300 hp
4500: 450 hp
5000: 475 hp Now my car on stock turbos: 3000: 160 hp
3500: 235 hp
4000: 325 hp
4500: 395 hp
5000: 405 hp And Seb's car on Sport 530s BEFORE inconel headers and tuning: 3000: 140 hp
3500: 180 hp
4000: 290 hp
4500: 410 hp
5000: 460 hp You can see that Jeff's PE's only slightly trail behind stock turbos to 4000 RPM, then after that they catch up and far exceed them. And these turbos actually look BETTER than Seb's did before inconel headers... strange because Thrash and MM_95TT both have dynos showing them to be a decent amount laggier than this. I still think there is something wrong with their cars and this one is setup correctly. Also, the fact that Jeff's car is on a freshly rebuilt motor with optimal compression plays into it. I'm trying to get Jeff to do a real world test to report on lag. I did this test on stock turbos and would like to compare them to these. In 3rd gear at 40 mph, I would punch the gas to WOT (at the same time triggering a stopwatch), and time how long it took to hit 14.5 lbs of boost. I know my finger isn't the most accurate thing in the world, but it should be within a 0.25 to 0.5 seconds. Out of the three tests I did in 60 degree weather, it took between 1.8 seconds and 2.3 seconds to hit that amount of boost on stock turbos. I wonder how much longer these PE1420s would take...
