Kickass numbers! Congrats man. Good build.

The heads you have flow quite a bit of air, and they do also flow well at higher lifts. When you increase the area of the intake runner and the plenum volume on an engine that is built like this you can see substantial gains at higher engine speeds.
I did not know that CID came out with these intake manifolds. They are a two-piece intake as well and priced well below the intake I have. But I don't think it will make any significant gains from my present set up. Very nice intake though, and something to consider for someone starting a build project.

Thanks. We'll see how she does at the track come Spring.

On set-ups similar to yours with the size camshaft and compression your engine has, you'd probably see a 20-25hp increase.

Something to think about if you wanted more out of it.

It was recently tuned by Jim Moran at Speed Inc. Initial tuning was done by someone else. Thanks for the compliment.

Martin thats a significant gain to be had, and yes, more is always good. What does this intake have that my intake does not compare?

That intake by CID definitely looks the goods, similar in appearance to a SB2 intake

20-25hp gain is a lot though from what Bolo already has

Would need some 1/4 mile runs back to back with both intakes to see the real difference

There was a 360" LS7 headed engine with .850+ lift that gained 50hp peak to peak and 60+hp past peak going from a hand finished (the Mast intakes are CNC from Mast) Mast 4500 intake to an out of the box (CID intakes are as cast not CNC) CID 4500 intake. It didn't lose anything under the curve in the operating range of this engine which was 4000-7500RPM. It even increased power as low as 4000rpm and never once made less than the Mast intake from 4000-7500RPM across the entire RPM range, not just at 6000+.



John@CID has told me on engines with less than .700 lift it's not worth it, and even in the low .700 lift range the gains won't be substantial. If the valve lift isn't providing enough flow and area at the valve for the larger cross section and plenum of the CID intake to shine then the gains will be decreased drastically. It is possible for BOLO to see gains of at least 15-20hp IMO with the lift and duration of his camshaft and where the engine is making peak power currently.

With .750" lift at the valve, it's possible he could see the gains mentioned.

That would be some gain of power. And yes, I will definitely see what she does at the track as it is right now before even thinking of changing anything.

Sounds good Martin, but as mentioned, I have to see and run what I have right now. As always, thanks for looking in.
