Freddy intake manifold vs stock

[Loomis112]

Hey all I got a redtop with a gt2871 on it and the previous owner threw on a Isis intake manifold.

I have the stock one sitting in my garage and im not really pushing anything over 260rwhp.

So just a couple questions..

I am wondering if it would be better to have the stock intake manifold back on there?

Would it help spool the turbo by not being a gigantic whale penis manifold?

Also I have heard the stock manifolds are good up to 400hp is that total bs or is there some truth to that?

Thanks for reading

Is it tuned ?

[Loomis112]

Only on an Apexi neo

So no not real its just a mild dd and occasionally I drift it

I'm sure if you go back to stock you'll have to adjust the fuel.

[Loomis112]

Yeah I could do that im just wondering if it would help? Maybe give back some low end?

Or does it even realy matter?

The stock manifold will give you a little more low end torque carrier if the longer runners. I use a Freddy manifold but I made sure to gasket match mine. I had to cut out allot of extra metal and then my welder. Added as bunch of metal to the other side to be matched. It was a lot of work but I think it's worth it with the Freddy. I used it with my 2871r and now I'm using it with my hx35. Only other problem I can think of is running top feed fuel rails. It only had 3 mounting points, not 4
