The HD7582 Street Turbocharger from Forced Performance is a great turbo for stock to mildly built LS motors.
The HD7582 turbocharger features the larger full size S400 comp cover and billet 75mm compressor wheel and a very high flowing 87x82mm turbine wheel. It is unusual to have the larger 82mm exducer size turbine in the T4 S400 size, typically it is a 72 or 76mm exducer diameter which results in high back pressure. You can expect anywhere from 500whp to 800whp from this turbo in a single turbo application depending on engine size and boost pressure. We offer 2 different size A/R ratios for this turbo, 1.10 or 1.25. You can tailor the response to suit your displacement and converter choice, the smaller 1.10 A/R for smaller engines like the 4.8 or 5.3 and the larger 1.25 A/R for larger engines like the 6.0 or a looser converter and larger camshaft.
The oil inlet is 1/4 NPT. The optional downpipe flange/clamp are set up for a 4" downpipe. It has a conventional T4 S400 Spec outlet flange.
The dyno pulls pictured were done with the converter locked so the converter could not make it look like the turbo spooled faster than it really did. Boosthoe with 6.0 LY6 and HD7582 with 1.25 housing at 13psi on E50.
