LS3 ported stock intake VS single plane:

SBE L99
Cam Motion solid roller cam
CNC heads
1 7/8" LT's
4000 stall converter
Holley Dominator
3:73 gear
3,100lbs

Weekend car that gets beat on and will see the track. Looking to maximize N/A top end power.

I'm considering going to a single plane intake

Question is will I see an upper RPM gain with the cleaned up Vic Jr? Or is the Super Victor warranted in this scenario running a 4150 throttle body on each?

The LLR cam will allow me to rev it higher than a typical hydraulic but I haven't found any solid comparisons using an appropriate cam tailored to each intake.

Note: already cutting the hood and adding a bubble. No room for a CID intake

Thanks!

I don't have a comparison dyno plot, but my ported Vic Jr held good power on the top. It's been a great combination for me... See dyno plot below.

I'm selling the intake in the Classifieds if you are searching for one.

In your application..... single plane all day.

super vic will make 40hp more then the jr if you can fit it.

the mast will make 20 more then the super vic.

On a square port? That's a big jump, and I have a hard time seeing my own combo making that much more power with a Super Vic vs. a Vic. Jr. Maybe I have them backwards, but I thought the cathedral Super Vic was a jump over the Vic Jr, but on the square port I didn't think it was much of a difference...

I can believe the Mast would make more power though...

That's not 40 horsepower... I see 569, then 564, then 558, then 556. The Vic Jr to Super Vic was 6 hp (the middle two numbers), then they got 5 more from the porting of the Super Vic. (so an 11HP increase with a ported Super Vic vs. a Vic Jr).

Please show me a link where someone went from a Victor Jr to a Super Victor and made 40 more HP on the same engine? Then I would like to see another where they show another 20 on top of that? Those numbers don't add up to me, but I'd love to be proven wrong.

BTW, I will be doing a similar dyno test with a Super Vic and a Mast intake on my engine whenever we can finally get the thing together and on the dyno. I will report back to Tech when that happens too...

You're only going to see 40hp on a motor that spins, none of this 6500rpm street crap.

Ok...

Please share a link to a dyno plot that shows a 40 HP increase of a Super Vic over a Vic Jr that's spinning, what, 7500? 8000? Is the OP planning on spinning that high or higher? Doubtful with a SBE as he listed.

Then I'd love to see a 60HP improvement on a Mast intake over a Vic Jr in the same vein...
