question about my new hpi rs4 evo, please advise!
 

I recently bought a HPI RS4 Evo. I like it very much and it seems to handle very good. However I am abit disappointed in the overall power and speed. Is there anything I can buy to help the power and top end speed? Exhaust? head? carb? fuel?

Any and all help is greatly appreciated!!

thanks

You can buy a better engine.

For the exhaust, you can change the pipe out for a better one.

For the fuel, you can try 30%. I wouldn't recommend that though.

Have you finished the break-in procedure? The engine can not reach its peak performance until after break-in.

engine and gearing are what you need, my rs4 3 will do those stock ratios in a little over 100ft:D

I've got a motor saver filter and RD logics tuned pipe. I thought the car was bit slow until I realized it wasn't shifting into 2nd gear. Now that I've got it to shift and its tuned properly, I'm pretty happy with the car.
