Obviously you are missing this extra connector set that came the Racetronix harness. Call Thunder Racing as they have spares in stock.

The MSD BAP I have is turned ~50% of the way to get 17v @ 10psi. Only think I dont like is at idle with vacuum the voltage is ~15.4v and I hope that wont overheat the pump after cruising a while. I was under the impression with no boost the voltage should be ~14v but its not so I may have a bad box. I e-mailed MSD but never heard back, I'll have to call them when I get some time.

Are you sure the MSD BAP is seeing vacuum? Does the voltage go down under 100KPa? The voltage won't hurt the pump but it will heat the fuel a bit more which should be avoided if possible.

thats 'hooked to the pump' voltage, it definately has full vacuum at idle, its hooked to the same line my boost gauge is hooked to. With no vacuum its at 16v, when I pump 15in/hg with the vacuum pump it drops to ~15.5, when I pump 10psi into it it goes to a little over 17v the way its set.

Got you now. I called TR, Doug is getting one out to me ASAP... great service!

Thanks for your help!

BTW, any idea where that plug should be located on the installed harness on the C5?

It's all covered in our tech note here:

You can go quite far with a single system if it is done right. Thunder Racing and a few other forum sponsors have them in stock. A dealers few sell boosters as well.

The plug is just after the relay. It is the same place the power lead is plugged for the drainage kit. The relay and booster should be mounted under the wheel well cover in front of the driver's side tire. There is a large open space in there and an existing ground location.

You could always use Blowerworks Super Fueler for better voltage control. We will look into what can be done with the MSD unit.

I actually had one of those turbofuelers five years ago, it came along with a carrol/votrtech C5 supercharger. It came with a 2 bar MAP and an inline fuel pump - thing was like 1500.00 though and didnt work all that well but it looked cool

My fear is the pump is overheating with the MSD. I have had no luck getting an answer from them on it and its possible its a defective unit. Under vacuum the voltage does drop slightly but its nowhere near what they say it is in their chart. If I drive the car for a 1/2 hour the pressure drops a little and it wont keep up at WOT, if I let the car sit a while it has plenty of fuel for one pass. I am moving the regulator up front and if that doesnt help I'll just rig up a dual in-tank 255 setup..
