Gto Hp Modified

The official power rating was not changed.

Gto hp modified. The 5 7 liter ls1 planted between the gto s fenders was given a 479 467 lift and 196 207 duration at 050 camshaft to accentuate torque output. Moreover the gto turned out to be a highly modified production car. Powertrain options remained substantially the same as in 1967 but the standard gto engine s power rating rose to 350 hp 260 kw at 5 000 rpm. At mid year a new ram air package known as ram air ii became available.

But never mind the test was the talk of the industry for years and really helped put the gto on the map. I review this sick 2006 pontiac gto that has been modified to have nearly 500 whp. Research compare and save listings or contact sellers directly from 22 2006 gto models nationwide. Most owners uprate the breathing of their car with a good quality induction kit and sports exhaust.

Conclusion after spending the day on the dyno and the street our gto was ready to hit the road course. It included freer breathing cylinder heads round port exhaust and the 041 cam. That cam helps push output to 350 horsepower and 365. The gto package included the f41 special performance suspension comprised of a 0 812 inch front swaybar a 0 562 inch rear swaybar firm ride shocks and 14x6 inch rally ii wheels without trim rings.

Now it was getting into the sort of performance territory that would do justice to that gto badge. The standard car came with twin exit exhaust but many owners opt for a large bore single exhaust. 2004 06 pontiac gto street high output intercooled supercharger 525 to over 800 hp the ho intercooled procharger system for ls2 and ls1 powered 2004 06 gto s produces a 50 55 power gain on stock motors running pump gas with 7 psi of intercooled boost. For the gto we were commanding a safe rich air fuel ratio in the 12 0 1 to 13 0 1 range.
