for the 944 and 951. In addition, you will soon see a Throttle Position Switch (TPS) harness and a Coolant Sensors and Idle Stabilizer harness. Like our injector and knock sensor harnesses, these are 1200 degree FIREBraid covered for a permanent solution.
This allows you to change only the portion of your harness that needs attention. Since we have all the sensors
covered except the stock Air Flow Meter (and don't plan to), you can either replace all vital systems or
just the ones damaged or tired.
We are just finishing up specifications and pricing on our 944S2 and 968 16 valve cylinder head upgrades. We
have Light Weight Solid Lifters, Racing Springs in two levels. The Standard Lindsey Racing spring and bullet proof "IRL" quality spring that you can rev as high as you dare, as well as full Port & Polishing. Give us a call if you're needing some 16 valve cylinder head work to get pricing and lead times. We should have it up on our web site in
the near future.
We just released our 911 Turbo (930) valve spring sets. We have a complete spring set with Racing Springs, Titanium Retainers, and spring buckets. We have various spring rates for different boost levels.
For those building 2.5L 951 engines, we just released our custom built WISECO 4032 Forging piston sets. We currently have them available in 100mm+.003" and 100.25mm oversizes and ring
sets for both Alusil and Nikasil bores. These light weight piston sets are affordable and available now.
We are making more progress with the Thermal Hard Pipes (THP) on our Twin Tube THP Intercooler for the 951. By the time you read this, we will already have a working system up and running and have begun testing.
As you can see above, we put the TT THP on the Super Flow and measured it's flow capability. We surpassed the estimated
500 CFM we were shooting for and achieved 517.7 CFM @ 25.49" of water column. To convert to 28" you use a multiplier of
1.06 which means the TT THP went 548 CFM. On a side note, the equivalent altitude was 4919 feet ASL and the temperature was 97 degrees on test day. This large number doubles the air flow of our air-to-air intercoolers. If it passes the cooling phase of the test, which we believe it will, it will mark a breakthrough in intercooling with endless possibilities with not only the 951, but anything you can dream up to fit one on.
Here you can see the cooling hoses routed on the Twin THPs. The coolant enters on the bottom of the THP
outlet and exits on the top of the THP inlet. This combined with the upward vertical flow in the coolant cooler
makes the system self bleed any trapped air. The fill tank is located under the hood (not yet mounted in this picture).
We managed to mount the 14" Long 6-pass Coolant Cooler behind the front bumper keeping things simple and clean. A universal mounting bracket was developed that simply slips over the bumper reinforcement bar and attaches with two bolts at the bottom. This can accommodate the 18" and 21" version just as easily by selecting
different bolt holes. Those would give you 40% and 70% more cooling power if needed. We are testing the smallest unit first to see if it's enough for the job. We installed the Coolant Pump under the windshield washer reservoir attaching to the chassis with a 3" saddle clamp. On this car, it originally had headlight washers. In order for the pump to fit in this area, changes had to be made. We installed the non-headlight washer reservoir which is at least 10" shorter in depth. That was something never used on this car so it
will not be missed. Does anybody use those? This gave us plenty of room to work with and still stay clear of the headlight mechanisms.
A few feet of Purosil Heater Hose and a handful of hose clamps tied it all together.
Next month we will post more details as our testing will have been well under way.
FINAL THOUGHTS
We greatly appreciate our Lindsey Racing customers. We get new ones every day and on most
days several. That inspires us and it's you that keeps the gears churning around
here and moving ahead with new and improved developments in both our parts line-up and customer
service. We continue to invest in facility, equipment, tooling and inventory which means
we are also investing in you, our customer.
If we fall short in your expectations for any reason, it is our goal to make it right and
keep you coming back. The old adage, "No News is Good News" is what we assume unless we
hear otherwise.
Until next month, we wish you many safe and quick laps.
