Okay, I recently bought an HPI RS4 2 on ebay. It's my new winter project car. My goal is to see exactly how fast I could get one up to for the cheapest amount. I'm shooting for 100mph, but sadly, I probably won't get there.
At the moment, I have a Wasp .28 on order. I'll try that out, and probably later on buy a nice italian onroad engine. But i'd like to try a cheaper engine to see if it's possible.
Here's my dilemna, I have no idea what to use for a header/pipe combo. I want something that will bump the powerband as high up in the RPM range as possible. What would work?
I know novarossi makes a few different 1/8 onroad pipes, but I can't tell one from the other
