discostig Manual mode ________________________ All day, erryday Donating Members 13,798 Member For: 17y 2d Gender: Male Location: Probably above atmospheric pressure Posted 10/10/10 08:16 AM Share Posted 10/10/10 08:16 AM (edited) I have 100% stock turbo and a manta 2x2.5inch, just ran a PB of 11.94 @ 120mph. 317rwkw, 17" street tyres (KU31s). Oh yeah 15PSI boost.Warning - it drones from 1300-1900rpm. I'm looking into replacing one muffler with stainless (I bought the mild steel exhaust) to save headaches when towing at 100kmh.Have heard good things about the Manta twin 3 but couldn't afford it! Wish I'd saved....though I don't like the idea of having to have turbo work done as well as mentioned by ratter! So guess I'm glad I didn't!
