LINDSEY RACING INTAKE 951, 944 2.5 & 2.7 8v



Putting up with the "far from perfect" stock intake manifold is a thing of the past. Lindsey Racing has after 18 months of development and refinement introduced a high performance intake manifold for the Porsche 944 at an affordable price. This is it folks!

It fits under the stock hood. It fits under your typical strut brace. It clears all water plumbing with a stock or aftermarket water jacketed turbo. It utilizes any existing hard pipes you have. In other words, you can install it on a completely stock 944 Turbo and it works with all existing systems. Of course it was not designed for a stock machine, but we felt it needed to fit one physically. What it was designed for is to bring out the beast in your engine. You may only think you have done everything to bring out the power in your machine. Look again. You want more high end HP and a much larger power band? This is the answer!

The stock intake manifold not only has inadequate flow when you port your cylinder head, it also has a 10% imbalance between the cylinders. The stock 951 intake flows between 206 CFM @ 28" on the first runner to 186 CFM on the third. Cylinders 2 and 4 flow between these numbers. The only way to insure all your cylinders are running at the same air fuel ratios is to deliver identical air and fuel to each one. Our Ported Heads with guaranteed equal flow numbers, our matched Fuel Injectors, and now, our intake manifold, are what it takes to be sure.

The stock cylinder head flows 180 CFM so the intake is not a huge issue since all the intake runners are capable of that. However.... Let's assume you're running our 232 CFM Level II cylinder head or our 252 CFM Level III head. You're feeding it with between 186 and 206 CFM from a stock intake. See the restriction? The prototype intake to this which resides on our 944 Turbo Project Car flowed 250 CFM on every port with the stock throttle body and this production piece is even better due to it's improvements as we moved into production. Now you can feed your ported head without starving it for air and supply the identical charge to each cylinder. Even higher lift cams with our heads or larger valved heads will need the additional air this new intake can supply.

With a stock intake, or even a extrude honed intake, you cannot correct the imbalance. If you tune your largest flowing cylinder (#1) to run perfect, the other three are rich. If you tune your least flowing cylinder (#3) to run perfect, the other three are running lean. Even if you're running complete stand alone engine management with exhaust temperature probes on each cylinder, and can adjust the injectors independently, you will have 3 cylinders receiving up to 10% less air than the others, causing the engine to be imbalanced. If you're using a single O2 sensor in the pipe, you're actually getting an average of the 4 cylinders and the actual values can vary. Without this intake, you are probably running too lean on at least the number one cylinder.

In comparison, it would be like having weak rings on 3 cylinders, clogged injectors, or leaky valves even if the engine is fresh. Far from optimum. Even the strongest cylinder is being held back trying to drag along the weaker ones.

The correction of the imbalance and additional flow can equate to a substantial Horse Power and Torque increase in a way not offered until now.

This intake is made from scratch. 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 and tapped for fittings for all your vacuum driven accessories. The threads for your stock banjo bolts have steel thread inserts. The bores for the runners are NC machined with a Smooth Flowing Radius in effect making a perfect velocity stack out of each runner without any obstructions in the air flow stream like poorly designed systems. The runners are aluminum cast from a high production pattern producing identical parts every time. The runners have a 20% taper from top to bottom. From the mold, they are NC machined on the ends to insure a perfect weld fixture fit and identical finished sizing from one to the other. The plenum is Cast Aluminum and NC machined for the throttle body and mating surface to the plenum backing. The opening accepts an O-Ring that perfectly seals the intake to the intermediate pipe. The threads are again fitted with steel inserts for durability. All intakes are Professionally Welded by our new "weld guy".

The intermediate pipe is made from Stainless Steel. The tube between the flanges is one piece and mandrel bent. Your throttle body attaches to this pipe and seals with an O-Ring. We have moved the throttle body up enough to eliminate those fitting problems commonly associated with installing a K27 sized turbo under the throttle body. Want to go to a even larger turbo? No problem. We have put this intake over TO4B, TO4E and TO4S compressor housing with no problems. One of the beauties of this intake system is the allowance of the throttle body to remain in the stock location. By doing this, it allows you to use your current hard pipes and everything else in the area without "any" major modifications. This keeps the flow of air the way it should be. Our flow testing of intercoolers showed that when flowing them backwards, they lost as much as 10% flow. Some other poorly designed systems require you to flow intercoolers backwards and buy all new and un-necessary plumbing.

The intake is available in two finishes. Fabricated finish which is the base price appearance or Fully Polished for the show and go crowd.

All manifolds are Ported and Flowed by our "Flow Guy". You are "guaranteed" a minimum of 255 CFM per port. The 4 ports will be identical in their balanced flow. Nobody else goes to the trouble to flow "each and every" intake manifold like we do, so you don't know what you're getting. Should you have a head/cam combination capable of more than that and would like additional CFM, we can arrange that at additional cost. The parts are thick enough to enter them and increase in side diameters and get more flow. 312 CFM has already been obtained with the stock throttle body. Increasing the throttle body size does nothing for you and may in fact hurt the performance. The one area where bigger is not always better. Don't be fooled by larger throttle body hype. If we needed one, we would have installed one.



We have separated the components on the intake. Your throttle body can be bolted directly to the intake manifold if you like, since the bolt pattern was duplicated. This will require you to make the necessary modifications to your throttle linkage and intercooler pipe to reach the extra distance as we did on our project car. Or you can purchase our INTERMEDIATE PIPE which allows you to make quick work of your assembly with everything you need.





If you're looking for the hands-down best designed and manufactured intake at an affordable price, then we got the piece for you. Order yours today! Allow extra lead times for optional thermal coatings and polishing.

We now have our Solid and Ultra Motor Mounts that are up to 10mm shorter than stock mounts. This will lower the entire engine 5mm or 10mm should you need additional clearance under your strut brace. In addition, it will lower the center of gravity of your car along with making it easier to remove the bell housing when servicing the clutch.



Intake manifold kits come with fittings, plugs, hardware, and dip stick mounting brackets (since it used to attach to your old intake).

INTERNATIONAL ORDERING



TO OUR INTERNATIONAL CUSTOMERS:


In the past, we have used a separate order form for placing International orders. We have quit using that process and are requiring all customer to use the shopping cart system built into the web site and it's check out process.

If you simply want a quotation and are not ready to place an order, then cut and paste the contents of your shopping basket, take a screen shot of the basket, or make a list of items and send us a email requesting a quotation with shipping.

If you need shipping prices before you make your final decision to purchase, then you should request that quotation by email and not use the shopping cart checkout process because you will be paying for the parts at that time.

Since our shopping cart and shipping estimator will "NOT" correctly calculate shipping charges on International Orders, we have it set-up to where the shipping will be Zero Dollars ($0.00) when checking out. When the shopping carts address process learns you are not in the United States by selecting your particular country, that's when it switches to equal Zero. That does NOT mean shipping is free.

Upon completion of the check out process, you will have paid for your parts but NOT the shipping on those parts.

Once we look over your parts ordered and calculate shipping weights and box sizes, we will send you an E-Mail with at least one shipping option and maybe several. We utilize UPS, DHL and the United States Postal Service (USPS) to deliver your parts.

Once you pick a shipping carrier and agree to the quotation by returning the E-Mail, we will be sending a PayPal money request for the amount of the shipping to be collected. If the parts are expected to be shipping out quickly, then you may receive that email quickly. If the parts are going to need to be built or something is on back order from the list of parts, we may hold off sending that E-Mail until we have the shipment ready to go. It can vary from order to order as to how we do that. If you think you should be hearing from us quickly, but you don't, feel free to contact us.

If you have special shipping needs or requirements, during the checkout you will see a SPECIAL ORDER INSTRUCTIONS window. Enter that special information there.

A good bit of our business is International and we have been taking care of those valued customers since 1999.
