JB4 Performance

[Spiguyver]

Hey guys, I've put together a video to capture the testing that I have been doing with my JB4 in conjunction with my Draggy. I know that many people compare 60-130, but really most roll races I see are started at lower speeds, like 40. So I made a custom capture in Draggy for 40-100 and did some comparisons across JB4 maps, and with and without an E Blend for fuel. Here's what I came up with:

Nice improvement! Might also go this way, with CLDP and the EGW wire.

I wonder if Map 5 would benefit more from a catless downpipe... Stock exhaust looks like a terrible design too, it's crushed in places and has terrible bends and shape changes. Maybe those are starting to choke performance a bit?

All jb4 maps benefit from dp upgrade

What I’d love to see is someone with an ECUTEK tune and a downpipe on a 2021 do a few pulls of 40-100 on their Draggy for comparison.

Also, for anyone that cares, I started an IG account spiguyversgarage

Looking forward to seeing that dyno

Appreciate the info. on the JB4 because that's the route I'm going to use. I have a CAI, catted downpipe and Ikon cat back exhaust. I'll follow up later because I'm waiting for my Eibach pro system to come mid Feb.
