just woundering what all you guys are doing for intakes. i was either planning on converting a small block manifold or having a sheet metal done but if theres other possibilities feel free to post them. also if possible post your pics.

From what I've heard a good port job on the stock LT1 or LT4 manifold is good up to 5-600HP. These intakes flow very good stock, but that's just my input.

i'm going to have to say single plane. i'm no expert but it seems to be a popular choice since sheetmetal intakes cost an arm and a leg. you'll see guys run an edelbrock vic jr with and intake elbows 90 degree elbow and a ls1 style tb.

If I did a turbo camaro (we're talking large single turbo like 88mm and up) I would probably convert a super victor.... more plenum volume and a taller profile.....

You could do the Victor E as well like most of us have done already.... It's a scrunched down version of a Victor Jr setup for EFI....

Edelbrock sells some for the EFI kit

You'd have to go with a sheetmetal or a converted one. The factory one even ported would be a bottle neck

When my car was supercharged I ran GM LT4 heads and intake went 8.92 best mph was 159. I dont think that you will need much more depending on your goals. My new setup with twin 74mm turbo's I am using a converted Super Victor but I have pretty lofty goals this time around.:angel:

If you are going to force n LT1 the stock intake is FINE!

What motor are you putting forced induction on? An LT1 flows FINE to at least 650 RWHP with NO mods other than gasket matching the intake.

A friend and I have made many forced inducion LT1s and shake our heads that people go to old style trash and throw away a perfect setup.

Good luck

If you want ~>750 RWHP then go with AFR 227 LT4 and air gap. I have a hybrid that may go there if I miss my goal et till then I will leave $$ in pocket...

Good luck

There is the testimonial...nothing can be added or needs to be, that says it ALL

i plan on making over 650 at the wheels. probablly around 1100. lots of guys are converted to a edelbrock intake and im curious to see what the advantages over my lt4 intake will be. otherwise i was thinking a sheetmetal intake. money really isnt the issue. i yes i do plan on going to an afr 227 race head.

Even 1100 hp at the Flywhel is ALOT. In an LT1 block that seems too high I would love to hear an LT1 block taking the stress, but I don't think it will hold.

we'll see what happens. if it blows it blows then time to put something else in it. but im some what on a mission to prove the lt1 and i really wanna push the limits. can anyone fill me in on how to go about getting a converted edelbrock intake and what im going to need to do that.

Well I hope the block takes 1100 and the mains stay in place. I am adding a main girdle since we saw cap walk with ~650 RWHP. Like I said I would love to hear you make >725 RWHP since my goal requires ~700 from my twins.

Good luck

yeah i mean ill probablly add a girdle and what not and do somethings to help out with that amount of power. still in a debate for a large single turbo or procharger f1a

I thought of this after an 8.92 in a 3300 car will require 1150 HP. So OBVIOUSLY he made the range you seek so there are setups in an LT1 that will take it.

A turbo car with AI 200cc ported GM heafds made justy over 1000 at the tires and ran over 150mph. Think you guys are way too quick to buy into "have to change everything factory" and throw rediculously large heads at everything.

Look on their results page.

How long has your 1100 hp LT1 lasted?

ABOUT 5 YEARS...5 SUMMERS THAT IS

That is great news. As I said I wanted to hear that an LT1 could hold the HP. I have had cap walk at ~650 RWHP on an LT1 and now added a main girdle. This thread tells me my 'goal' of 900 Flywheel and ~725 RWHP is not a dream with a stock LT1 block.

I worried the webbing on a stock block would give <1,000 hp. I know LT1 is alot stronger than old style, but wasn't sure how much.

Thanks, sorry for the redirection of your thread hope it is clarity for you as well.

Good luck

My brother took a stock LT-1 intake and ported it to 58mm and cut out the center section for his AS&M Monoblade TB and then ran his TT to it...he's kicking a good 800 HP with that setup.
