BUT, and that's a big butt I have yet to read where anyone has personally installed it, dyno'd it and posted results. So I too am leary of this pump since it's rating from GM doesn't support what my engine build is going after in numbers. I too hope that this GM tech can enlighten me and explain how this works and hopefully has some past builds with numbers to back it up.
I also asked him if I could video the build and the dyno and he said they are currently in process of doing this and posting it to their website. I don't know where it will be but hopefully at some point there will be video of my car. The dealership is Fairway Chevrolet in Las Vegas. The tech/tuner is a guy by the name of Samuel Smith. So if anyone else has any knowledge of him please chime in. So far though I have heard all good. The procharger guys at ATI ranted about him.
I'm looking forward to being a SC member and cannot wait to start playing with a 600+ HP Camaro. I love the term Violent as described in Padre's posts.
When it comes down to it, I'm certain I will err on the side of caution and if I feel like this pump insn't adequate, I'll have him step it up to one of the recommended pumps from this thread.
Peace.  |
I had Sam Smith tune my car. I researched some of the other speed shops in town and felt that he had the most knowledge in tunning these LS engines since that is all he does. I have talked with him about different fuel system set-ups for my car and he doesn't like to use dual fuel pumps because if one fails, you won't know until it is to late. I went with the ZL1 pump for my car, but I'm running a boost a pump also. I was losing 10 psi of fuel presure with just a boost a pump. Now that I'm running both my fuel presure stays right around 58 psi. I would probably be ok with just the ZL1 pump, but am using the BAP since it was already installed. If you would like any more info you can PM me or post in my journal.
BTW! Padre
build!!!
