I'm not a noob on what is needed to go fast. I'm 5
Unless you have been faster and are keeping it under the hat
From what you said you have an 11 sec car.
So NO you dont know what you need to go fast.
Your posts have turned into preaching what you need now and you havent answered any questions.
Your goals have moved all over the map in a few posts faster than a 9 sec car

Here is the cheatsheat for ya
Lots of things have changed in this game and really fast.
If you want a 1000hp tire fryer you could do that with 400hp and a regular set of radials=a tire fryer is a tire fryer.
If you want a 10 sec street car that actually runs 10s on a real street
That's needs a much different approach.
If you want a 9 sec track car different approach
If you want a 1000hp that actually works on the track and street way different approach and you would need a hell of a car not just a good motor.
