New LT1 Intake
I guess they will need to find out how wilsons got around that.If it is actually an issue.I dont think that will be a problem beings that lifter guides in ls1's are composite too.

I think composite would be the way to go in order to cut down on the heat transfer. Here are some thoughts.
1. Need to figure out the runner length to pick up the 3rd harmonic wave.
2. Need to figure out the taper in the runners.
3. Need to figure what average CSA will work best.
4. Need to leave some meat where the runners meet the head for easy additional porting.
5. Make the throttle body intrance capable of opening to a monoblade.
6. Make it so that down the road a bolt pattern will fit a Gen 1 SBC. You will be able to recover more cost and hopefully a profit.
I think there is already a Marine intake that is very similiar to what you want to build but is for a Gen 1 SBC.

yes with some sorta insulation would greatly help..but the composite wouldent hold much heat either way....
also if we were to copy the ls1 guys this would be considered a bolt on and could go a little ways into the bolt on record....and could go very far for lt1 hydralic cammed guys trying to make over 450rwhp...not every1 has the time/money ellis does....
also ellis i like how you did that with stock rails i had no idea...one of the reasons i decited to not gobig with my lt1...didnt wanna do a dedicated system/rails....also im guessing you removed it and went mono now right?

Imo, dont be afraid to ditch use of the stock fuel rails. That was the downfall of the edelbrock intake if you ask me, the stock rails restrict the crap out of what you can do with the way the crossover is configured on them and their shape. if you can figure out how to get that out of the way you can make yourself a little more room and depending on what you do you might be able to make a little better injector firing angle. but the absolute key with the hardcore ltx crowd that would buy this type of thing, is results, screw what the thing looks like it had better make power or it will be disgraced just like edelbrocks whole package.

This is great. The interest in this is overwhelming. My buddy at the shop is going to **** a brick when he sees this(The shop is KLJ Corvettes in Hanover MD). Originally, We were going to build this just for my 93 vette because of the dissapointment of the edelbrock(6.5hp and 6.2trq on a h/c lt1 vette
) He has the design but is on the fence whether to make it out of composite or aluminum. Judging from the strong showing for plastic, I think we will go that route. When we get it build we will flow test it, then dyno a 95 z28 with bolt-ons before and after, then my vette before and after. Were pretty sure this intake will be good for atleast another 15whp over the stock manifolds. Thanks again for the suggestions, and keep them coming.

im not sure if your blowing smoke...its a great idea dna lt2 are becomming VERY POPULAR with how easy they are to get and cheap to run decent...if you could keep the cost under 500 for an intake that will outflow 33cfm heads, youd be rich
well i guess i thought you got a mono plate from dave? anways goodluck, you goana get that thing out before the end of the year? you do anything beside weight change?

I'de be more interested in the midrange gains than topend gaines. If someone's looking for just topend power they could go with a single plane. And make sure you let LT1 throttle bodys bolt up to it, having to spend $400 on an lsx 90mm throttle body would definatly hurt sales. And if you guys actually come out with it and it has proven gaines I would definatly buy one.
I’m subscribing to this thread.
If hot oil splashing on the underside is a concern, you could hang a shield or plate of some sort? Just a piece of sheet metal with a half inch between it and the bottom of the manifold should protect it from the heat.
I’ll agree with the fuel rail concerns. While I would pay more than $400.00 for this setup and go for a new fuel rail system, some guys would want to keep the stock stuff. Maybe you can make it to accept the stock rails but with a modification (to the rails) that rout the crossover around the manifold instead of through it. This will untie your hands on the crossover point.
With the right tunning length, you should get plenty of power. Be prepared to make five or six of them all different before you figure out what works best. What you calculate on paper may not work in the real world.
