so i must be revving my engine wrong, cuz when i'm not in gear, its damn near impossible to blowoff....
maybe you're confusing the amount of time and "work" involved to get to the higher RPMs in which your turbo is spooled.
You're turbo is gonna spool at the same(ish) RPM regardless. When you lower the rotating mass, the engine can get to those higher RPMs faster.
So its kinda like the turbo spools sooner....
dee dee dee no its not easy to blow off without being in gear hence no load. thats why I said the more load the harder the turbo works. the turbo is not gonna spool the same. I have 200+ passes on a 3,000 lb. inertia wheel dyno jet. on the dyno the 35r cracks the wastegate @ 4,800 rpms. on the street its 4,600 rpms. the 3,000 lb inertia wheel doesnt simulate the exact load that the s13 actually has. less rotating mass helps spool up. if it didnt I would have 26" spinners with Mickey's instead of 15" welds.
