RE: Big Inch upgrade!

It should be back together by friday . I'm going to put a 100 or so mile on the dyno to seat the rings and check the tune just to make sure it is safe . No hp pulls just cruising it around . My previous tune will be out the window because everything has changed . Should CC the heads tonight to see how much needs to be removed to get the right compression . I let you know how it comes out .

RE: Big Inch upgrade!

I have 127 ci el bruto in my 88 springer.SOB thats how to build power cubic inches,compression12.5:1 red shift cam .715 good pipes mine and sound good(yea patting my own back but also what other said)makes 158 hp 163tq and only trick is staying on.Havent hit the nitrous button yet and shouldnt have added a second stage.motor is enough.I can tell you from when i had nitrous ot th 80 inch evo it does boost the hell out of torque.Ok maybe Im lil crazy but I have fun.
to answer your question yes cube ad power and the bigger the crank the more torquy it is.If using a 5 inch crank call me I want one ride

Here's my two cents.
I put an 88" S&S stroker kit in my 64 pan.She purrs like a kitten. Best mod I've invested in.

Have you blown up the 127" already? 200"? Randy at the"The King of Cubes" can help you out.The only thing is a 200+"is going to be a lot taller motor.

I'm considering upping my stock 96" to the Screamin' Eagle 113" full kit. Have any of you done this and have you had any negatives to doing the upgrade?

Thanks!!!
