Nice thats some very good power sounds like you're going to hit your 700hp pretty easy once you get it tuned more.

how high did you spin it on those runs? what AFR?

well we drained the break in oil and put in some 10w30 mobile 1-made a couple adjustments to the tune and made 680hp and 606ft lbs.
peak power was at 6300 rpm

our 700hp goal isn't too far away

did you take some video? I would be curious to see if it revs faster than a conventional style manifold......

Great numbers so far!

Does it need a different cam? Aren't you leaving a bunch of power on the table with a peak that low?

yes we could put in a different cam and pick up more rpm,but,our goal was for a broad tq curve and usable power.high rpm horsepower is for light race cars not heavy street cars

BTW-we still have more rpm in it-just haven't pulled it that high yet

I was having the dream of 402ci, but I never thought it would pass the 600hp...

Very nice thread...

congratulation Shawn

Not at this time. We have a few things in the works, and it's still on the dyno, so it won't be too long.

Wow, quite impressive. Now if the price for an ITB setup would just be a little more competitive, I think they would be on a lot more cars considering how much I've heard they tame really big cams. Talk about having your cake and eating it too.

The Harrop is actually priced very modestly. There's a company we saw at PRI out of Australia that had some systems that were twice the price. They were works of art, but pretty damn pricey.

So roughly what is the cost of the Harrop? $3000, $4000? Just curiousity.

Shawn could tell you exactly, but I wanna say 4-4500.

The ones we saw @ PRI were twice that!

I can't wait to see the final results. I hear the throttle response is INSANE. Almost scary to drive if you don't slow it down in the tune.

That intake would look really nice in flat black. Ninja style.
