Well, this goes to show you that all F's are not created equal. We just did a before and after dyno on a ISF that had only 6k miles on the clock and was bone stock when arrived. This car performed very well stock and made a great gain without anything but the headers.

Base line #'s on this car before the sikky header
375 hp and 322 tq

After the Sikky headers
409 hp and 341 tq

It did make slightly more 1 run but we threw that run out.
Here is the video with graph

Yes, it is high for a stock car. We all took a double take and even re dyno'ed several times to make sure it's not a fluke. This run was at operating temp to. It did drop a little like normal when heat soaked after 4 or 5 back to back runs, but it was still higher than what we have seen for a stock F. Guess this guy got lucky with a well put together motor? No other explanation.

Awesome!

So 34 with the headers alone. How does the interior with headers only sound compared to stock? I wonder what that freak ISF will make with exhaust and intake added.

Thanks,

Tom
it's actually fairly quiet. Don't think anyone would have a problem talking on a cell while its floored. It is noticeable that's the headers are on there though. It's been raining like crazy here so if the weather clears up we will try to get a vid of a drive by so everyone can hear the sound with stock exh.
