Anybody run this intake?
This would be great for my project. I'm wanting to move lots of air, but run a moderately low boost pressure for the "spare" engine I'm building...It's Lindsey's redesigned intake manifold.
This makes a lot more sense to me, I've always had a problem with the stock design, and according to Lindsey's site, IT DOES have a problem. I know some people are extremem opposites in terms of liking a company, but I was just wondering if anyone has tried this intake.

Would appreciate any info. Thanks.

It's looks to me to be a fairly good design. Although, I think if I were designing it I would make the runners longer for a bit more streetability, but they could be plenty long and the picture deceiving. Symmetry is never a bad thing either

I don't think anyone has yet,,that was the prototype that is on Dave Lindsey's car at the moment. I think they expect a few in this month, along with the intermediate pipes. I have been talking to him about it with their MAF or weighing the great benefits of TEC III engine management with Chris White of 944 enhancement.

You should take a look at Speedforce racing's new intake manifold. I think its a better design than the lindsey unit. Not that lindsey's is a bad design, i think its more for lightly modified cars. Notice the lindsey intake uses the stock pipes, stock throttle body, non reverse flow design. from the pictures ive seen of it, part of the intake still sits over the hotside of the turbo. The SFR intake has a large plentum with small runners that have velocity stacks if you wish. so you get good top end and low end Hp. It also uses a twin 52mm throttle body that flows much more than the stock unit. its a reverse flow design so non of the intake or its pipes sit over the turbo, so no heat sink. no, i dont work for SFR, i know firsthand they make good stuff and ill probibly pick up one of there intakes once i get the money.

I don't think the Lindsey Intake sits over the hot side of the turbo either but the spool pc may a bit. Also remember that the production pc will have the intake repositioned between 2 and 3 runners. It would be very easy to thermal wrap the hot side of the turbo with all that working room. The one thing I like about the Lindsey intake is that it is CNC machined from new material and the internal bores are smooth. Tim does make great stuff, his exhaust is the best.

Yeah, i wasnt trying to put down the lindsey intake or anything. it is a good design, frees up lots of space, and it flows evenly across all runners. i think there both good products. it appears their both in development stages and things could change. Both of them would be better than the stock manifold IMO.

I totally agree, I didn’t want to sound negative in anyway. Ive bought from both vendors and have only good things to say about them. I love to see new things for the 951 <img src="graemlins/drink.gif" border="0" alt="[cherrsagai]" /> <img src="graemlins/beerchug.gif" border="0" alt="[cheers]" /> <img src="graemlins/burnout.gif" border="0" alt="[burnout]" />

It has been great lately it seems that there are going to be a lot of new parts for our cars.
The MAP kits
Intakes
Suspension geometry correction
Intercoolers
etc
Competition is great it improves the breed (the reason I also like the v8 M3's running against the 996 GT3Rs, but that is another story).

It does seem that performance companies are dumping many new products on us and I love it. I cannot wait to see how competitive they get with these MAP kits. Especially if they use the same base computer(link).
Don’t even get me started on the V8 M3/911 GT3R thing. The v8 M3 is not a production car and was only built in a limited production run blah blah blah. Na, I think its pretty cool too. Porsche has to retaliate with a flat eight, oh yeah <img src="graemlins/burnout.gif" border="0" alt="[burnout]" />

The Lindsey intake uses a cast plenum.This peice is not CNC'd.The only thing that is CNC'd is their flange. We are also using CNC flanges. On top of that our whole intake is constructed out of 6061 that has been heat treated to T6 standards. This aluminum can handle thermal loads much better and dissipate much more heat then any cast aluminum. Our intake is also smooth as a babies butt on the inside;^)
Now onto some of the things to look for when purchasing a new intake manifold. The first thing is that you want the plenum to have 2-3 times the displacement of the engine. Ours has twice the displacement of the engine with 312 cubic inches(5.25" x 3.5" x 17"). Another thing to consider is how the runner length will impact the power band. Long runners will promote low-end torque while short runners will help top-end power. Ofcourse you need the right header to really make everything work in unison. The factory tri-Y header inst going to work to well with a short runner intake so we decided to make a 4 into 1 equal length header that will be a nice complement to our intake manifold. A final issue that must be addressed is flow to each runner and velocity. You need equal amounts of air from each runner making it into the head and you also need velocity. Without either of these, you are screwed. Take care.

Tim,
Is there a way to utilize the stock IC pipes with your intake? The "LT1" type throttle body is visually appealing...do you have any flow numbers (graphs) that you could post from a real world setting?

It's hard to compare Lindsey intake and Tim's intake just from the pictures, but somehow i got a feeling that Tim's intake is the one i would choose.
Tim,
iam interesting about to velocity stacks you are using.Any pics available ?

You need equal amounts of air from each runner making it into the head.
* the runners flowed "identical" CFM and the 4th was only 1 CFM different even though it still had sharp edges and ledges within. This goes to show how the design works even in rough and unfinished form. Even though, each intake will be ported by the flow master to increase and insure no CFM difference across the part.
The injector flange is precision NC machined from T6061 Aluminum to accept your injectors and fuel rail perfectly. The Plenum backing plate is also machined from T6061. The plenum is cast aluminum and NC machined for the throttle body and mating surface to the plenum backing. *
