Thats right. This graph mods are test pipe, then added bc set at 17psi. and spectra short ram. Still has cat on it so afr's show about 1 full point lean. Im totally stoked on these numbers. Boost spiked about 21psi on the dyno and held at 17psi strong. Car flat out rips.
modded stock box no fitler vs. spectra short ram. I also did one with the filter and it was 308whp. 365ftlbs. stock box run was started a little earlier in the run and thats why the boost comes on sooner. though peak power and torque were up. spectra held the topend better and was alot leaner. im thinking its the bigger maf housing. Im running the spectra until I go with the cobb sri. I think cai are overrated. ive never seen more power on the dyno or et on the track from a cai. Just my opinion. Once the car is rolling sri is not an issue. Its just simple logic.
