D1SC + GT350IM + 11psi

[venumous]

Pulled the trigger on my blower from Beefcake. Interested to see what this thing does on 93 octane. From the looks of things it's going to be a monster. What boost are you PC guys running?

Are you getting a larger TB? The IM won't help if you're chocked by stock TB.

 

[venumous]

Disagree. Air is going to be forced through the TB so it will still make more power.

Is this going to rev auto for the tune?
I'm lookin at the same setup

 

[Grim12]

This might be me next summer. Looking forward to see how this works out.

Not familiar with Rev Auto. I'll look into them.

I'm curious to see the results over the stock manifold as well. It seems the na guys make a good jump in the upper rpms but the same thing is being done on the stock manifold when the rev limiter is raised with a Centrifugal. If it makes over 20hp/tq all being equal over the stock mani I would be surprised (I hope I'm wrong) but I still wouldn't make the purchase. A degree in timing or a lb of boost would equal the gains for a lot less. But since you have it already I'm in for the results.
Same logic with the TB.
One cool thing about it is if it's not a huge benefit you could sell it to a NA car & use the money for a fuel system for e85 & make a huge proven jump in power.
This is just my opinion & thinking out loud I hope that the OP or anyone else doesn't think that I'm bashing the 350 mani or his build.

I asked because they just got a gt350 intake 2015 with a centri setup.i plan on doing just that.

Certainly don't consider it bashing. I've considered going to the stock IM as well but haven't decided yet. I agree it would certainly pockets some cash back for what may be minimal gains. I'm still going to talk to a few builders before finalizing my plans. I'm sure there is a benefit to it when you rev higher with boost but I'd like to keep this thing in one piece too.

I'm going to give them a shout tomorrow, thanks.

I seen that you had FF when you were NA. I forgot to mention that e85 on a FI cars pick up between 60-80 rwhp on same boost just added timing. Most cars can pulley down at the same time & get over a 100 rwhp jump. Just something to consider if you sell the mani.

Ehh IMO don't fix what ain't broken. Nobody is going any faster with the GT350 IM and reporting loss of torque. Is centri guys already suffer from lack of torque why make it worse just to gain a little up top.

If it were me I would throw a 16-18psi pulley and add a wastegate set to 11psi. If you don't run in the 9's at 138-142 then something is broken.

So far with my Paxton I have been 10.34 @ 135 on 8.5psi in Texas heat. Adding wastegate and going up to 10psi... MAYBE 11 once the cool weather comes back around. All on 93 octane.

I think the intake will make more power, we've been 8.1ss with the stock throttle body, so I wouldn't be too concerned with that

I agree, the boss has shown significant tq loss but with a Paxton I've seen them make great power and tq still. I'm sure the gt350 will be better then even that.

 

[venumous]

Agree, no reason at all it won't make more power and I've been told the same by Beefcake, JDM, Lund and a local tuner. I've run my buddy's Lund tuned 14 with everything but an upgraded intake manifold and I pull hard on him. There is NO doubt the IM makes the car faster NA as well, anyone saying the opposite is misinformed or poorly tuned. I know some guys have posted on here that they picked up 3-4mph in the 1/4 NA.
