335xi vs Mercedes C43 AMG

What's up guys sitting here at dinner with some of my buddies and we're talking about who's car is faster. My buddy has a 2017 Mercedes C43 AMG and the car is fast no doubt about it. I have a 2013 E92 335xi with FMIC, charger pipe, downpipe and JB4 running map 2. Now obviously we haven't done it yet or else I wouldn't be posting but what do you you guys think who is winning ? I honestly think he has no chance but I don't wana be bias so I'm asking what you guys think.

Do you have e85 near you, map 7 and e30-e40 will give you the best chance. and do a 30 roll in 2nd gear or 50 roll in 3rd gear, if you're doing a dig turn off DTC completely, put the car in 2nd gear and brake boost launch from 3k rpm. Make sure you don't hit the kickdown. You will r@PE HIM from a dig no doubt. Do some practice, and when roll racing shift at 5500rpm, good luck! Take videos and post.

What's on his car?

Our friend has a c43 amg with downpipes exhaust and custom dyno tune. I haven't raced him but my friend in his m235i beat him by 5 cars. He has fbo and custom Bef from Enzo

Should go in your favour, depending on the length. With your mods and tune, power difference will be minimal, but you have the advantage of being roughly 500lbs lighter.

From a dig to 60mph, could go either way. Beyond that, it should swing in your favour.

I thought map 5 was the best for a mix ? I haven't really researched it that much but something I definitely want to do. Can you suggest how much to put in so I have no issues ? Like can I fill up until there's a quarter tank left of 93 octane and fill the rest with E85 ? Also why shift so early I thought peak power is optimal to shift at around 6500 rpm right before redline

I should have clarified he is completely stock it's a lease lol and really 235 had him by that much ?? Those things are fast didn't realize that fast since I've raced a few and beat them fairly easily

Map 7 is the fastest map and requires either 100 octane or an e30+ mix, with low gas put in 2 Gallons of e85 and 3 gallons of 93. And peak performance is 5500rpm, 6500 is too high and the turbo is out of its efficiency range for e series N55

I would say to 60 mph would depend on his traction. To the 1/4 mile will depend on your fuel and if you're having timing corrections. On 92 octane I could only trap 104 mph on the stock turbo. 109 mph is a pretty big gap. If you add some ethanol to the tank (E30) I think you will win. If you run pump gas I think you will lose.

Idk where you're getting 4.1 from every article I see is 4.5-4.6. I have PSS tires so no issues for my traction at least the launch is absolutely brutal now with the mods. Thanks for the input deff wana have a race with him !

Interesting I'm gonna have to do some more research to see what's best and safe for me to add in the ethanol safely. I'll try out shifting at 5500 I didn't know that thanks for the info !

Ya don't worry. You'll win. I beat one from a dig with my heavy ass e93 plus a manual. I passed him once I got to 3rd gear while I was limiting boost in 1st and 2nd. 3rd gear I was targeting 16psi.

We took off at the same time and I didn't launch it or anything. He got a car length from me early, but by 3rd gear I walked him.
