HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

Looks like the Lokar one that I ended up with as well.

Yes, that is the Lokar and it was far too long, so I pulled the end off and and cut it to the correct length cheers

Doc, just pull the end cap off (side nearest the throttle body) and trim both the sheath and the cable. With the throttle the correct length there is little friction in the cable and the throttle works well (easy pull and quick release!).

Everything is hooked up and I tried to start the car tonight, no go. No spark, no fuel. Time to start troubleshooting.

Good news is that the oil pump primed quickly and pressurized the system quickly.

I take it that the engine cranks over? What does your fuel pressure look like? If you lack fuel pressure and it sounds like the fuel pump is kicking on for two seconds, check the check ball valve that is attached to the fuel pump. Mine ended up being stuck and not providing fuel.

I believe that the issue is in the relay/fuse box that we constructed. I'm not getting power back to the ECU when the ignition is turned on. I did not have time tonight to do much, hopefully it will be something minor and quickly fixed tomorrow night. I jumped the fuel pump relay and it is working fine but with no signal to the ECU, it does not come on.

Hey Tim, Everything is looking great. Where did you snag the Nylon coil relocation spacers from? Also how much space between the Driver's head and Dual MC bracket?

Nylon spacers are from McMaster Carr. Space between valve cover and dual mc is 1/2" (guess, I didn't run down and look).

Fire in the hole! Franky III started tonight. That's the good news, the bad news is the the back of the oil pan is leaking Sad

I believe that I fixed the leak at the back of the oil pan. The canton racing pan that I am using is very thin around the mounting lip. I added a small piece of angle iron to the rear of the pan using the two rear bolts. That should give greater support to the middle of the back of the pan where it was leaking. Started it up, let it run for a few minutes and no oil Cool

I ordered 4 relays on line for 2.99 each. Two of the four are bad and don't switch when you apply current, that was the problem. I ordered some Hella's today, should be here tomorrow. In the meantime, I just hot-wired everything.

Yeah, relays can definitely make a difference. I ended up with a couple of ford ones that seem to work fine. Been using resistor/diode based relays ever since I noticed a difference in reduction of turn on/turn off pops in my car audio setups. I know it's a little late, but here's a link for anyone else looking for relays:

Interesting note on the relays, turns out that they were fine, the problem is that we daisy chained the trigger from one relay to another and used one common ground. What was happening was that there was significant voltage drop across the coil, enough for the switch to fail. Guess you learn something new every day! All is well now cyclops

This is how I have mine wired up and it runs fine. scratch

No, we daisy chained the trigger voltage from the ignition switch, not the main power.

Car moved under it's own power yesterday. Spending the day dealing with loose wires and hoses, then off to have the y-pipe built and then to the tuner by the end of the week.

Weighed the car yesterday, Franky III weighs 11 lbs more than Franky II.

Car goes to the fabricator tonight to build the y-pipe and install the 4" exhaust system, I'll have it back tomorrow night. I have a leak at the back of the pan, not sure if the pan was bent or if it is leaking from the rear main seal. I plan on pulling the crossmember and dropping the pan over the weekend. When it goes back together I'm going to put a 3-piece crossemember on so that this is not so much of an issue in the future. Dyno and tuning is scheduled for Monday.

Now the fun news, I'm scheduled to race this bad boy at Barber with SCCA over the labor day weekend. I'll test and tune the car next Friday and then race Sat and Sun. Since there is not a class for the 948, I'll be put into SPO with the 500+ hp cars; I'm hoping for rain What a Face

Lots of people have had issues with the 3 piece cross members cracking, so keep a close eye on it...

I've heard different stories on that issue. Some say there was a bad batch made, others say that there has never been a problem. At any rate, I plan on keeping a close eye on it. It came off of a race car (951) that never had a problem with it.

I seem to remember MarcA had issues with the three piece as well, not sure it can handle all the torque of the V8. But, I'm getting old and killed way too many brain cells, so, best to look it up on the old board, or maybe Marc will chime in. Smile

Got the car back, sounds and looks great with the exhaust. The fabricator did a great job.

Car is up and running, will be raced this weekend at Nashville with NASA-MS. Had to put in a larger radiator to keep it from overheating. Still getting used to the non-boosted brakes.

Nice video Tim! Got any times during the test session? I can see some early braking in spots, but like you said, gotta get used to the non-boosted setup. Just out of curiosity, what caliper, pad and rotor setup are you running?

I love me some Little Tally. It would be nice to get a bunch of 948s out there and have some fun.

If I remember right, I think I actually got a ride-along from you a couple years back. I think it was a gutted red 944 at the time. Very Happy
