1/4 mile toyo r888r results

[echio22669]

Took car today to track with r888r with better results. Ran tires at 25psi, 4 passes with best time at 11.582. All 4 pases with LC. Last time best I could do was 11.96 with same toyo tires except ran tires at 28psi.

What do you guys think? Running Alex@Alpine stage 2 tune. No downpipes or any other mods.

An 11.6 with a fully stock car is pretty impressive. Good work!

That's a solid run. Launch control?

Yes. Ran 11.2 this past weekend using launch control as well

I would expect those numbers from a stock M3/4 on sticky tires. The ET is expected due to improved launched traction. The trap speed is also in line with a stock DCT. It does not seem like your tune is giving you much.

All the stock m3/m4 in my area seem to be running 12.1 - 2 at best. I ran 12.2 stock on street tires.

Yes, that's my point. Improving launch traction makes a huge difference in elapsed time. Power can be seen in trap speed. 118mph is consistent with stock power levels for a DCT M3/4.

I let LC autoshift. Should I shift manually on the top end ? People tell me to shift at 6k rpm?

It depends on your tune and the shape of the power curve. With the stock tune, you need to redline 1st and 2nd and shift around 7k for optimum acceleration.

Forgot to mention, I am now running VRSF downpipes

Is that 1.5 or a 1.6 ?? Wow that's really good track prep! You're car is hooking up extremely well. Nothing really left in the launch just better shift points.


What track is this do you know the DA ?

I need some better tires for the drag strip. Ran a 11.3@127mph with crappy 60'.

1.6, track is in Edinburg,Tx. Not sure about the DA. Cracked a 11.04 @ 124 couple weekends ago. Going this Friday see if I can crack a 10.9

I assume 93octane fuel? So Stage 2 tune, catless downpipes and triplerrr tires? Great times! Have you tried installing drop in filters and removing charcoal mod?

No drop in filters yet. Never heard of the charcoal mod? Yes Octane 93 with stage 2+ Catless tune and r888s @24psi

In your stock air boxes there are charcoal filters. People remove them when installing drop in filters like k&n or bmc. Frees up some hp and a little more Turbo sounds...

I went to the track for the first time last week. 2015 M4 convertible. Mods are drop in filters, VRSF mid-pipe (stock DP’s) and BM3 stage 1 93 tune. Car ran a consistent 11.7 at 122. Used launch control but it would not let me
lower the launch RPM. Was launching at 3k and was getting fair amount of tire spin. 60’ times were 1.8-1.9. Was running 20” 666M on Michelin PS4 at 26 psi. If I go back, thinking of running lower psi and adjusting tune to cut 1st gear boost by 20%.
