HA HA. Second raza I mean noelle . This guy shouldn't even be allowed on the forum , how does he expect to do business with people when he has such a bad attitude and character. Nevertheless his cars are only just as fast as bolt ons and tune m5's. Here's another secret these guys don't even have any 0-60 or 1/4 times. Their too scared to launch on the stock drivetrain, Talk about proper R & D. So after 30-40k of money spent you can't even launch the car properly 😂. What a waiste of a company and customer service. To any body considering them , review your options CAREFULLY.

Running my Low 6 or rather say high 5 tune since 2 years, pretty long for driving with blown motor I must admit.

To me posting dyno sheets and hp numbers is totally worthless, only thing that is significant as a true result of a cars power increase is the accel times. Very simple which all the people around the world can relate to, no matter what mods/fuel.

I also thing that a fully built forged F90 with upgraded turbos should go at least into mid 5s 60-130. You can also understand why people are doubting your builds with such a poor time (6.1). Only way to prove them wrong in my eyes is by dragy or a time slip.

I wish you good luck in all future builds

@Sales@RKautowerks any updates on the builds you've done yet, in terms of 1/4 or 60-130's?

That's correct
yea super fast! They also pulled seats and I believe they changed the rods as well. I'll have to go back and read my conversations with them. I can't remember for sure

They told me for some of the runs the car had stock motor. They changed both the rods and pistons based on my conversations with them.

I would like to build my car to run in the 9.5 range.

So basically they picked up 3 tenths over my car but had to change turbos, pistons and rods. That's an expensive upgrade and having to pull out seats.. haha

Still impressive but too over the top for me on a brand new car.

Agree! At least they gained though. I think we will see many built motor cars soon that can’t even surpass your times.

I might build the motor for piece of mind. My issue is finding someone I trust. Forums are a horror show for built motors.

I mean. I would go by the 60-130 times, which fell by a full second and half for startline performance. They did a 4.6ish. Another Russian tuner did a 4.8 on the 60-130 vs like 5.9-6ish for a stage 2 e30. I believe those built times were also on 93 octane.

Still curious on rk times ... they should easily be low 5s.

Pretty big gap between our pump gas time and your pump+e30...

Yup

I don't think there's anything else that needs to be said on this subject! Very quick time and have not seen anything quicker on this site.

Coming from a guy that is going to build his M5 and go all out it is great to see so much progress on this platform.

Congratulations and good luck squeezing more out of it!

So far, NOT A GOD DAMN PERSON can build an f10 or f90 and be reliable. Show me one that has been performing reliably for some time ever since the build. I'll wait...

The money some people expect you to pay just to forge the motor vs the results you get out of that built motor is foolish.

Maybe we as owners of the platform are a bit greedy too bc we just want more and more but none of us can actually say what "fast" really means to us for a 4 door family sedan that weighs 4500+ (depending how many donuts the owners like to eat a day).

Me personally I'd just love to have someone build the motor that can reliably run at 800-850 whp and also put out results to match that power.

Dyno don't mean anything to me sorry. Prime example from the most recent Vmax event. RK builds a sick engine for Evolve according to all the talk that went on a week or so ago then Vmax comes and car runs 206mhp. Same event last time a stage 2 stock motor Wrench Studios car ran 210 if I'm not mistaken according to some of the data I seen from the Vmax event. But the RK/Evolve dyno looked and sounded sick.

Don't waste your money on the built motor unless you want a fucking headache.
