I've seen plenty of water temp sensors mounted in that location.

Look in the Hewland FTR manual (https://starracecars.com/wp-content/uploads/resources/FTR-Manual-3-09.pdf), which shows the Tripoid Gaitor setup. After removing the spiral locking ring, the black...

The part that the rubber boot sits on needs to be removed. I think there is a spiral retaining ring, looks like the end is at about the 3 o'clock position in your picture #2.

To remove those,...

I would remove the sensor before putting the cover back on. Of course, you may need to position it correctly before tightening it, so that the voltage reads correctly. Look in the Care & Feeding...

My current P2 car is running with 75% airflow blocked. Coolant temps are running 180 degF on a 65 degF ambient day.

I use various sizes of Garolite sheets (available from McMaster-Carr) taped...

If monitoring the MoTeC ECU with the ECU Manager, be sure to reset the errors after starting. There can be transient errors like low voltage and runt-signals while cranking. Any errors that come...

I would start with the troubleshooting process (about page 31) found in the Renesis Turtorial 2012 found on this page:

I would suggest checking with Neel Vasavada, 310.314.2005. I'm not sure if he's still doing business as Apex Speed Technology, but I think that phone number might be correct.

I successfully ran at the front of the P2 field using 6 & 8" wheels (like an FC), because that's what fit my previously Sports 2000 chassis. You will be fine running the FC tires. If you get to...

DId you try unbolting the clutch basket? Just remove the clutch cover, and attack the bolts holding the clutch basket that contains the clutch plates.

That info looks like your dash in an MXL Pista or Strada. If it's a Strada, it doesn't have any logging memory, it's display only. If it's a Pista you can log the channels you have connected and...

Change your configuration, you probably have a channel expansion, LCU-One Lambda or other Aim expansion device configured. The message is just indicating that it doesn't see the configured device.

You need a crew with an umbrella.

There are no stupid questions, only stupid answers!

You would connect the tacho output from your MSD ignition to Pin 8A (small connector) (RPM input) on the Pista harness. I would expect there is an RPM input wire in the harness. Here is the wiring...

I would be adding channels an ECU can actually use for either engine protection, or improved performance/reliability.

-- Oil Pressure (protection, rev-limit engine on low oil pressure, stop on...

The 2.5 isn't legal for P2, only the 2.0L version. In P2, engines have stock internals, but free external components with a specified flat plate intake restrictor. The P2 rules are pretty clear...

Hoosier Tires would be available from

Contact Worldspeed, I believe they ran their cars on their own dyno routinely to make sure they were in top condition.

Here is the link to the page with all the entries for every class:

To me that looks like some kind of centerlock adapter on a standard hub. I think the wheel pins were probably the original wheel studs for a 4-bolt wheel.

So, you might consider switching it...

Might see if these ARP 7/16-20 wheel studs would work for you...

Lots of choices from Summit for 7/16-28, and you can use their selector...

I'm pretty sure you will need to send the ECU to MoTeC or Daryl Drummond to have it erased. Then Daryl should be able to supply a new "unlocked" map that will run the engine.

You can email Daryl...

I hear Spec Prius and Spec Tesla are on the way... New Tesla charging station going in at the Buttonwillow track.

Tesla drivetrains are available on eBay -- the small 300 hp units should to...

I would make sure you have the correct injectors for the engine/ECU. I worked on one particular engine (not a bike engine) where we changed injectors, and while they had the correct flow, the...

I sent you an email with his email address.

You will never achieve top speed at Willow Springs until you are completely flat from T6 until you reach T1. That is what a pro driver in a PFM would do. Top speed would probably be 140+. Min...

You might be able to adapt an LD-65 type 4-piston caliper. Those are relatively common and certainly keeping with the spirit of the rules -- race cars need to be maintained -- with parts available...

4 gallons of 91 octane plus 1 gallon of 100 octane mixed in the same fuel jug.

A floor under the engine and diffuser do help reduce drag, but not necessarily create downforce. Believe it or not, a large open area under the tail bodywork can create quite a bit of downforce --...

The Radical SR-3 is a spec-line car in P2, and as such requires no modification even though certain parts exceed the normal P2 limits.

It can be a very competitive P2 car in the right hands.

opps, wrong info...

Most Sports 2000 used mechanical fuel pumps, so to the wiring was very simple (Master Switch, Ignition Switch, Brake Switch, Rain Light). if you want to protect the fuel pump wiring, then I...

And sometimes you just have to learn to squeeze the throttle instead of asking for everything all at once (usually a sign you have overslowed). If you carry more mid-corner speed, you will find...

I would check with Lee Stohr. That's right in the wheelhouse of what he's been doing the last few years. They 3D-print sand molds for castings. He makes CAD drawings of obsolete race car parts...

First, run the car given the setup sheet. Run enough to understand if there are any issues, and to where the driver can get a consistent laptime for a few laps in a row.

Then remove some of the...

I was going to forward this invitation to the west coast S2 group, but I will tell you that none of the cars would meet the criterea, either too new ('89,'92, 2000), wrong decals, or common...

The tire machines I'm familar with only grab onto the rim, and don't care about the center. The balancing machines on the other hand use cone adapters to fit different wheel centers. I had to...

Yes, that's correct. I would also check the resistance (ohms reading), between the alternator body and chasisis ground (alternator does not have to be turning). This should be less than 1 ohm. ...

We noticed the lack of voltage from his first on track experience. While not running full revs, it should have been charging, instead the car was running like a total loss.

For voltage output you...

The P2 Rules were developed in 2013 for the 2014 season. The original rules sought to keep the most allowance of any of the restricted classes we were trying to combine. So the FIA CN cars and...

You'll typically get about 2.5 to 5 laps per gallon. The best way to determine this, is pump out all the fuel (at least all the fuel the pump can pick up). Put 5 gallons in, and run a session. ...

Yes, we can test it using the MoTeC CAN Inspector program. We have installed that on your computer already as part of the utilities.

Drill holes in the new front shock cover. That's the way the cars all ran in the pro series.

Carbir race cars were built by Brian Utt who also runs Motorsports Composites in Wisconsin, 262-375-1930. I would give him a call to inquire as to what cars he might have or can make.
...

This can be calculated, but we need to know:

What are the gear ratios and the engine speed (RPM) you want to initiate the downshift?

I did end up making some adapters for PFM / DP-02 / Van Diemen FC cars.

Your dash will use the MoTeC Dash Manager to communicate with your original MoTeC ADL dash (3.2u is the firmware version).

You will connect your UTC to the car and laptop, then turn the car on. ...

I think 104 is too low.

I have a dynapack dyno and can make adapters for your PFM. I expect they will be the same as the ones I use for my Van Diemen P2 car.
