I have been running Bosch III injectors since the spring and I have been very pleased with them, I ran 11.67@115 with them in my 6.0 L92 L76 1969 Firebird, not bad.

I lost compression in 2 cylinders a while back and tore it down. I broke a couple ring lands between the compression rings so I picked up some new pistons. While I had it apart I figured I may as well get a new cam, I have never been really satisfied with my choice so I called Geoff Skinner at Engine Power Systems www.engpwrsys.com. He has his own lobes that Comp makes for him so I wanted to try them. He set me up with a 234/246 .602/.606 114+3 cam.

I put it in, first thing I noticed was how much quieter it is, very nice. I started tuning and it tuned very easy. I did a couple of hard runs and my injector duty cycle went to 97% (39lb @ 58 psi). I called Jon a FIC fuelinjectorconnection.com and told him what I changed and he recommended that I send my injectors back and he will make them 42 @ 43.5 which is 48 @ 58. I put them in last night, reset the IFR and retuned.

I did a full driveablility tune first, not just WOT. I tuned in OLSD first to get the VE table and timing tuned in up to about 5000 rpms and then tuned in MAF only. I switch it all back on and it ran great. The STFT corrections for idle to 1600 are at 1-3 and above that it is in the 0-2 range.

These work great, AFR @ WOT 12.8, duty cycle 75% at 6400 rpm shifts. Idles very good. 800 rpms.

I do have the injector data from Gregs DVD in my tables. The Bosch III is the same as the 24# FRPP skinny (280 155 931). All I changed was the IFR table. I tried the stock 2002 F car settings before and they worked too. I have not tested the F car data with the new injectors.

Great setup. I can't wait to get this thing back to the strip.

The moral of this long story, don't be afraid to buy or have your injectors resized. They work great and they will save you a bunch of money. I will get lit up about how these do not work right and all that but I also don't have a load bearing dyno so that's the way it goes. ]]> 69LT1Bird http://www.ls1tech.com/forums/fueling-injection/1207374-more-info-resized-injectors.html http://www.ls1tech.com/forums/fueling-injection/1207370-more-info-resized-injectors.html Sat, 21 Nov 2009 00:44:24 GMT I have been running Bosch III injectors since the spring and I have been very pleased with them, I ran 11.67@115 with them in my 6.0 L92 L76 1969 Firebird, not bad.

I have speed inc high flow rails and mounting tabs already, wanting to use stock fuel lines, looking for around 6-800 hp to the tire.

I also already have a versafueler driver box and will be running at least 120# injectors or 160#.

So basically I need the lines up front and the parts in the pump, any help from sponsors are greatly appreciated. ]]> RS_SS69 http://www.ls1tech.com/forums/fueling-injection/1207105-e-85-fuel-system.html http://www.ls1tech.com/forums/fueling-injection/1207059-empty-fuel-tank-using-fuel-pump.html Fri, 20 Nov 2009 02:48:56 GMT I've had gas in my fuel tank for almost a year now while doing my engine build and it wasn't stabilized before hand.

I want to have a working gas gauge, but don't know which Auto Meter Sport-Comp gauge will work correctly (2 5/8 or 2 1/16").

If I knew what the full/empty ohm ranges are suppose to be I could figure it out on my own.

I'm needing a pre-filter for the pump.

I don't want something that's going to inhibit flow to the pump on the inlet side, but I don't want to leave it bare and unprotected.

I was looking at those Summitt/Russell etc canister filters that have -6AN male fittings on the end for ease of installation.

http://www.summitracing.com/parts/SUM-230101/

It says it's for carb'd applications, but since it's on the input side I don't see why it wouldn't work. But I'm afraid to choke the pump.....

Any suggestions? ]]> jonathan_ed3 http://www.ls1tech.com/forums/fueling-injection/1206341-fuel-filter-external-line-bosch-44-a.html http://www.ls1tech.com/forums/fueling-injection/1206239-injector-size.html Wed, 18 Nov 2009 01:14:06 GMT What size injectors do I need?
