Horsepower increase

[donm]

Now that I've installed a DVEF on a single plane intake and swapped out the 4-1 exhaust and downpipe for a 4-2-1 set-up on my carbed '80, I was wondering if anyone knew the actual horsepower I've gained. The car is definately quicker but has anyone done any research on what the actual power increase is? Just curious. Is it 10? 20? 50??

I'm going to guess 10 hp. Only real way is a dyno though. Here three runs on a chassis dyno is $90.00. When my car is back together I'll be taking it up and trying it out. I'm just guessing I might have 120 now after the mods.

Chris, where's the local dyno?

There is one if not two in Kelowna. Reading up on the type they have, it does not show true? HP but is used mostly for baseline and then tweek and run again to see if any improvement. That was what I was told anyway. There are several in the the Fraser valley as well.
