I finished the oil plumbing last night and ran it for about 20 minutes until it warmed up. No oil leaks and the SC got nice and warm. So far so good. I now have 3 belts, one for the PS pump, one for the alternator, and one for the SC.

I have an elbow ane 2 couplers holding me up now. With any luck they'll be in early next week.

 

Nice work keep us posted.

Bill,
Are you coming to LRP at the end of teh month?

 

I registered, but I'm not listed on the web page. Looks like I didn't get in.

 

a question.
did you use a MAF in place of the AFM?

 

Looks good so far; how's the tuning coming along?

 

No MAF, MAP, so the computer knows the correct amount of air being fed and calculates the correct injector pulse width, either NA or boosted.

 

Not much change in the tuning lately. I just got some new data logging software installed so I can really start the tuning process and my alternator failed (this was about 2 weeks ago). While waiting for the new alternator to come in I started plumbing work which lead into the headlight work, which just got finished last night so I can drive it again. This morning was the first time out of the garage and on the way to work the d**m alternator failed again!

I'm not having much luck with these rebuilds. My original failed at BeaveRun last summer, 8 hours from home. I patched it together enough to get me home, it failed again in my driveway the day after I got back. Put in a 'new' rebuilt and it failed immediately. Put in a 'new' replacement and that one lasted about 8 months, until 2 weeks ago. The latest replacement lasted about 25 minutes before it fried. Sheesh.

 

Would you mind sharing the info on what your using to conver to MAP?

 

It's using a GM ECM, 1227749, from a Syclone turbocharged truck, so it knows all about boost. More details at http://mywebpages.comcast.net/p-928/749.html.

 

Bill... "on the way to work the d**m alternator failed again!

I'm not having much luck with these rebuilds. My original ........" ....................Have you inspected the front engine wiring harness they often deteriorate insulation falls off and you get cross feeds , shorts and that can fry alternators .

 

Bill,
Are you using the stock injectors? Have you verified their flow rate at stock pressure and their stock duty cycle? If you plan to use the stck injectors which I understand to be 24#/hr at 43.5psi (a standard pressure for flow rate measure) will you increase the duty cycle and or fuel pressure?

Nice Work!

I'm running stock injectors and stock fuel pressure for now. The '749 computes injector pulse width based on MAP, injector size constant, RPM, load, and a number of other parameters. I expect I'll run out of injectors soon and have to upgrade. About 300 hp is the limit with stock injectors as I understand things. MotorMan ( http://www.injectors4u.com/ ) has used ones that are cleaned, tested and flow matched for reasonable prices. I'll probably go there for a set of Ford 30# low Z injectors when I buy my next smaller pulley.

 

Good thought Jim. I checked tonight and didn't find anything unusual. That doesn't mean it's not there, it could be just that I didn't find it.

 

We all look forward to seeing some 16v supercharged numbers...
It's nice to see people putting things together.
