I haven't been as active on the forums lately... YouTube and Instagram are where I post most of my content now. If you aren't already subscribed/following there, you're missing out

That being said, I have exciting news I want to share! I took the car to the drag strip after doing a ton of modifications (listed below). My previous best was 10.90 @ 136mph with full interior, stock diff, stock axles and radial tires. I did a bunch of weight reduction, upgraded my diff, axles, suspension and tires and went back to the strip. Results below:

1st pass (20psi): 11.29 @ 128mph with a 1.94 60ft
2nd pass (25psi): 10.53 @ 137mph with a 1.73 60ft
3rd pass (28psi): 10.36 @ 134mph with a 1.59 60ft

The old record for a manual N54/N55 with stock BMW chassis was 10.70 @ 135mph, but I'm now the fastest after beating it by almost half a second! Yes, Ghassan Automotive went 9.6 but they have a custom back-halfed drag chassis. I think I can run 9's as the car was misfiring during my 10.36 pass.

The car has made 752whp and 691wtq at 30psi. Being at ~28psi with a misfire, I'd guess it was making ~700whp on this pass. Log attached.

wow congrats

so this is with no custom tune. Just a jb4 with the jb4 back end flash for single turbo with e85 with port injection

is this right?

No, he is custom tuned by Wedge.

Believe he has a custom BEF.

However, our BEF is pretty well sorted. I ran 10s in my xi a bunch on our OTS hybrid PI bef & pures. Took maybe 3-4 passes to dial in for 1/4

Also, nice work sir. Love the thoroughness of the write up (per usual, lol).

Just replied to your same comment on 1Addicts. This is a custom Wedge tune as someone commented. But like Dave mentioned, the BMS/JB4 BEF is very good and I've also ran multiple 10 second passes with it.
