Default Worth it or NOT?

Do you think switching to Victor Intake Manifold with 90mm over the LS6 and 1 7/8 headers instead of the 1 3/4 worth it on a SC'd setup?

On a FI set up I would think definately yes...Alot of other variables though. Amount of boost, HP your trying to achieve, etc...

N/A, depending on CI and the amount of "upgrades" to the motor most likely not.

Goal is maxing out the D-1SC (15-18psi) and then 50-100 shot of Nitrous on top of it. Numbers should be close to 750rwhp on Boost and close to 900rwhp on the bottle. The motor will most likely be an HPE forged 370-396 with either ET or AFR heads.

I have been considering upgrading my headers as well, but doubt I will. I have other parts and pieces I need to get before worrying about upgrading what I already have.

And from what I have heard, you will see very minimal gains from the IM upgrade on a blown application, but I have no experience... I still intend to keep my LS6 IM!

depending on what size piping you have going to the TB, My opinion is; having a TB bigger than the tubing going to it is kinda pointless. 90mm is 3.54" in dieameter. So if you had 3.5 tubing it would work.

just my opinion.

With a fully built bottom end and some decent heads running a D1, then only putting down 750rwhp, I would hang myself. A built 347 will give you 800+ if done right.

The highest dyno from a D-1SC i have ever seen was 760rwhp or so. I really don't expect the D-1SC can push anymore air to make more than 760rwhp. Maybe at that level the mods i listed above would help give me the last 20-30rwhp to get close to 800rwhp, but i dont think the D-1SC can do it on its own. An F1 maxed out would put the car over 800rwhp easy, but not a D-1SC.

If you think about it.... I still have around 13000 RPM left on the blower now and im making 630rwhp on a mustang dyno running 10.1 C/R (650-670rwhp on a Dyno Jet). So another 13000 RPM from the blower on a 9.1 C/R motor would maybe give me another 3-5psi at best which would put me around 15-18psi and maybe just maybe 700-720rwhp on a mustang dyno (720-750rwhp on a dynojet). I just dont see how i can get 800rwhp from the D-1SC. If you have seen a guy who did it please show me the link or the dyno sheet.
