Oh good God. I'm guessing you just gained like 80 whp for like $500.snowth1ef wrote:interstate pull for anyone who is curious, stock motor prior, now topswap, 60lb injectors, e85, 3.6 pulley. http://www.youtube.com/watch?v=nVnmIlNAwvU
Re: Topswap build!
Well high compression helps, and I'm down to a 3.6 pulley. people argue like 10-20% more power with comparable mods on a high compression block vs a low compression one.
Re: Topswap build!
Yeah 80-100 is about what me and my tuner are thinking. ballpark of course. I think with tuning credits and the 60 injectors i ended up being like 800ish into it. and many many hours of work, but well worth it!nos4blood70 wrote:Oh good God.

Re: Topswap build!
I have been wanting to do this upgrade for a while now. Every post about upgrading to a supercharger says that the lower end will fail because of the internals are not strong enough. Wouldn't the internal parts be the same? Thanks for proving this upgrade is real, not a myth.
This is a great write-up! Keep us informed on any breakdowns or issues you come upon. There will be many people starting this upgrade.
