Default to boss manifold or not?

Have a chance to get a deal on the manifold. Not sure if it would help or not. No converter, stock gears. Procharger d1sc in 10-11lbs. Might be doing a tran brake here soon. Not sure on my power level.
Anyone know if its less restrictive or just shifts the powerband? Im current reving to 7250rpm

That's pretty much it. Its kind of like having a box style intake that moves the powerband up. If you're shifting at 7250, you won't be taking full advantage of the intake and will expierence some torque loss. Not that you will notice it a whole lot since you are boosted. What you may notice it the car will feel a lil lazy on the street requiring a lil more effort to get it going, but it will scream up top.

Unless you're turning the motor to 8grand I don't think it's worth it. But that's just me

If you were n/a, I would not recommend it. But being boosted, I think the extra manifold volume could be useful in filling the cylinders at all engine speeds. If you're getting a good deal, I say go for it. If it doesn't work out, you could always switch back.

It moves the whole curve up a range and paired with long tubes it's a beast

IT will help your road racing. But definitely recommend the other valve trains parts to go with it. You'd be able to stay in gears longer and get a little more top end. Who doesn't like that for road racing?

Thanks for the responses. I think I will stay with the stock manifold for now and put the money else where theres a couple things I need to finish.

Boss manifold is highly overrated. My car made 435/420 with the stock manifold, long tubes, JLT CAI and custom tune from GH, while it was still n/a. I shifted that combo at 7250 with a 7400 soft rev limit and ran 11.50's. Unless that intake is near free, I'd pass.

Car ran good, but there are a lot with similar mods that go faster than mine.
