Amp draw with OEM alternator. I'm upgrading my fuel pumps to (2) 255 Walbros as well as installing (2) new radiator fans for my vertical radiator set-up. http://www.jegs.com/i/Derale/259/16925/10002/-1
I'm somewhat competent in electronics but I can't find the information, at least presented in a way that is clicking. I could probably get away with smaller fans if it is going to be an issue.
I've also read that you can upgrade to a truck 145 amp alternator, if using a relocation bracket like the one sold by CBR, but I cannot find any information on what "modifications to valve cover" entails.
Thanks for reading.

The 145 amp alternator bolts directly in place on an f body and the stock belt works too, you just don't reuse the rear support bracket that comes on the stock f body alternator. Search my posts and read my alternator post. Get a used truck alternator if you want it to last.

Thanks for the replies, the mentioning of a relocation bracket was due to installing a turbo with forward facing manifolds.
I'm just curious if anyone with dual walbros and twin rad fans that are around 20 amps a piece experience any significant voltage drop that may compromise the vehicle (i.e. significant loss of fuel pressure).

The car when stock, can easily pull 60 or so amps, so you will be over drawing the system.

Verdad Gallardo The large case alternator (145 amp truck alternator, careful, there is a small case truck alternator that is 105 amp, get the 145) should fit with the relocation bracket you mentioned. It's roughly and inch larger in diameter but uses the same exact mounting points and wiring that the f body alternator does, the belt should even be fine.

I finally found a parts yard within a reasonable distance and they said they have a few in stock, so I'm going to give it a shot. Gonna give a used $50 GM one a shot before I shell out for an aftermarket one.
Thanks again for all of your input.

Sweet, hope it all works out for ya, at that price you may want to pick up 2 and have one on the shelf.
