Whitt - I don't know how the Radix setup is but, I needed ~.600" spacers for the rails when I put the bigger injectors in my truck(non radix).

 

Whitt - I got my injectors in today. With both ends of the inj seated, I needed a 5/8" spacer. I found a 1/8" dia galvanized tube in the plumbing section of the hardware store and cut what I needed from it and put in longer stainless screws. It looks like it came that way.

 

I'm making a change back to a 01 PCM and a cable type throttlebody.I've been on hold waiting for a PCM from Speartech and a cable update on my LS1edit.I'll pick up some 1/8th" pipe that sounds like a good way to go.I just wish I had more time,my business really takes off this time of the year,I may give up pay someone to finish my truck.

 

Any reasons why you just don't go for a Speed Density setup in lieu of the MAF?

 

Yes,because I allready have a Pro-M MAF that's big enough to support 800+hp with a MAF calibrator.Other than that I would consider going with a F.A.S.T.electronics setup using speed density.The Pro-M route is a lot cheaper.

 

Ah okay, I wasn't aware ya had the Pro-M MAF and associated bits already.

Is that MAF a standard housing or one they make?

 

At a glance it looks like a stock MAF when you remove the airfilter it has a tube that I assume samples the airflow while allowing unrestricted flow through the device.The calibration unit routes the wires from the MAF through the calibration unit back to the PCM.You can plug your laptop into a port in the rear of the unit to adjust the frequencies sent to the PCM,they sent me a preprogrammed curve calibrated to my injector size,from there you display and modify the curve on your PC or manually using the ***** on the unit.

 

Hrm, do you have any pics?

I assume that the little sample tube is like 1/4" in diameter as it sounds like they did away with the GM electronics.

 

Do you have a part number of which Pro-M MAF you have?

 

I really need to get my digital camera back from my daughter.The tube is to one side and I don't even think the housing is GM,much less the electronics.Like I said it looks stock at a glance,but with the filter removed it's very different.They build the unit to the required spec the unit I have is rated at 800 flywheel horsepower,they can build larger units.
