trying to decide what intake to buy, LS1, LS6 edelbrock pro flow or victor jr

100k stock bottom end LQ4

317 heads with patriot springs and retainers

cam is 230/238 @.50 around .600 lift and 116 lobe seperation

c6 manifolds flipped

Right now all I have is the long block looking at getting two 6265 precision turbos 60lb injectors I want to make 650 rwhp on a budget

I can get a ls1 intake for $50 LS6 for $300 pro flo for $450 or victor jr for
$450 plus an elbo

what is the best choice? how much power will a after market intake make over a stock on with FI

I have seen 60 rwhp gained from switching from an LS2 intake manifold to a FAST 92 intake manifold, with no other mods so I know the newer FAST intakes work very well. Bob

FAST 92 + budget = oil + water

60 rwhp is alot for a intake swap now I see why they cost so much

I made over 1k on a ls6 with stock tb. If you cant swing the $300 right now go with the ls1. When you pressureize it, it will flow fine especially at 650. If $ is that tight you will have other areas you need to spend the money.

If I could fit a ProFlo XT, it would be on my car. It's one of the few glaringly obvious choices for a cathedral type headed setup. There are many very good results already from this intake.

Why is this a true statement. I have seen a lot of cars in my area with fasts on FI cars doing just fine. All the cars are 620+ rwhp and are pushin 10 pounds or better on boost. Can you explain this to me?

You can almost buy 2 Proflows or 3 LS6 intakes for the price of a new FAST. They work though. No question about that.

I understand the price issue, I was just responding to the guy based on him sayin a fast equals disaster. I would go with a used LS6 if price were an issue. I have one on my car now because i cant find a used untouched 92. Dont wan to change my injectors and rails for an intake swap.

The whole idea of his post was that FAST and budget don't mix just like oil and water don't mix.




There are several very well known cars out there that are still running an LS6 to this day. It's a good budget option.

how does the stock truck intake compare to the ls1 and ls6

Does anyone have any dyno differences or information between and Edelbrock Vic Jr w/ elbow and for example an LS6. I have only seen N/A comparisons, wanted to see how the edelbrock does behind forced induction compared to an LS6.

Hot Rod mag did an LQ9 build comparing intakes the ls1 was down 9hp over the truck intake and the ls6 was only slightly less. makes me wonder if i should keep my truck intake. of course this was NA. does it really matter if im going FI?

fast manifolds seem to work well in all but really high boost situations, was just sayin that if on a budget like the op stated he was that the fastmanifold isnt very wallet friendly..

if it were me, I would do a $30 ls1 intake and stock throttle body.

sure, the others might make a little bit more power, or a lot more power if you are at 7500rpms, but for a non all out build just add 1 more psi off boost and youre good to go

anyone running the stock truck intake I am thinking about grinding all the
junk brackets and tabs off of it and painting it
