Well Happy with my latest run at

[CK64]

I ran my car at a track formerly known as Firebird Raceway in Chandler AZ on Oct 28th.

The only mod to this car is the Dinantronics Sport set to "race" (+4 psi) and I ran a mix of 5 gal 100 octane unleaded with 9 gal 91 octane. 32 psi in the tires, temps in the low 80's. Best times were in Sport+ and trans in D. I tried running in DS and launching at a higher rpm, but ended up with wheelspin. I also noticed that in 4th and I think 5th gear, the revs were really high before it shifted ~ 7000 rpm. I am going to try to manual shift next time.

Best time of the night (out of a whopping 4 runs) was a 13.61. I'm not sure why my mph is so low ~ 96 mph. I never ran faster than 96.46 mph...

I just ran a 13.6 with my 2013 328i. I have a JB4 running map 2 and just a K&N drop in filter. As for tires, ha, I ran some 5/32 stock runflats!

Nice times. Red lit 2x..and that Vette was sleeping at the light in run 1. If nothing, it shows the car is pretty consistent.

Everything else stock? NICE!

Well, the car also has an Injen Intake which i forgot to include in this post. So those two things only. I made a detailed thread, Here is the link. Still trying to figure out how to get the video up on the website. http://f30.bimmerpost.com/forums/sho....php?t=1381911

Half of you guys are trapping less than my N52 328i - but those ETs are definitely quicker.

[KraigF30]

My F30 335d with remap only = 12.100 @ 113.5 mph. Second fastest run of the day was 12.140 @ 115.7 mph.

No aftermarket parts whatsoever. Completely stock other than a software remap. Stock runflat tyres too. 2015 plate. 18k miles.

I was waiting an while, and my Logs files did show my IAT been excessively high - and that I believe has affected my tune.

And I was spinning my wheels through the gears - just about to order some new rubber - M PS4's

I do not want to go down the route of an Wagner intercooler - so just ordered an K&N panel filter.

Next time on the stip -I turn the car off and push it to keep the IAT temperature low.

Enclosed log file on drag and also one from the weekend.

15th Was my Drag Logs
22nd Was my test runs yesterday

As you can see my IAT was running 118-140 doing the drag - however powerruns were 94-110

I have a Wagner intercooler competition and holy fuck does it make a difference !!!

[M2_MEDUSA]

I love the xDrive that I have my 428xi can launch at at 3500 rpm with zero and I mean zero wheel spin, not a single sound comming from my tires and holy fuck does it take ur breath away lol. I'm going to the strip here next week and going to do a 4,000 rpm launch

How are you only running 14.1 I was running 13.7 stock. Probably because you may still have runflats. I currently have dinantronics sport + downpipes Injen intake and Wagner intercooler and rear seats all stripped out so I should expect to see high 12's.
