Now that I feel very comfortable with my rearend mods, I'm getting closer to ordering this 13-6 kit with a new set of Michelins. Just having some anxiety about being excommunicated from the Ford warranty church...

Instead of the JLT 127mm intake, I'm planning to use this textured plastic JLT intake pipe, Ford Racing 65mm TB with an upper pulley and Lund tune from Van. Curious what power gains would be with and without the upper pulley.

That's similar to a resonator delete. Throttle body with Tune usually about 30-40 RWHP. Upper Pulley adds about 10-15 RWHP on average.

Every car is a little different. I've seen 675 to 700 with the upper pulley and the 13-5 / 13-6 kit. Also depends on heat and DA at the time.
This may sounds stupid, but what the hell does 13-6 mean anyway?
Forget I posted that, I got it! and now I'm thinking about it!
Hey guys, I would do Van's rear BMR suspension first with lowering springs of your choice to make the car go straight and then add the magic of Van's awesome 13-6 kit. I made 693 RHP with it. This kit kicks major ass... For you guys saying that the 13/14 Shelby GT500 is weak in power stock when you bought it. L O L My 550 HP lightning feels like a slug compared to my Shelby when it was stock and its like a pinto with Van's 13-6 kit.
I think I got lucky in that my car really wants to go straight without any suspension upgrades. But, no doubt, I will be upgrading the suspension and once I am done roasting up the stock tires, upgrading those.......Steve
It goes straight even with traction control and advanced track off?
Holy Crap!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Totally new car just as I expected when I bought it but Ford really held back. This kit changes everything. Will admit I toasted the clutch a little at first and if you spend 30-40 minutes jumping all over it the engine does heat soak a bit. But holy crap the car is BEAST.
I have not even done a pulley yet, so when I get used to the new power there is still more to look forward to.
Van is the best (answered every question in under 45 seconds....really) and I thank him and all others here for this thread of encouragement. I have never modded any of my cars before but I feel really confident in the quality of the kit and the tune..........Steve
LOL
13-14 GT500 STAGE 6
Just in case anybody else was curious.
13-14= year...
6 ---- the number of seconds that it takes you to shit your pants when you feel how fast your car is w Vans package.
