I honestly would be surprised if it didn't surpass the 600 mark with good seal and a vacuum pump.
Wanna try a electric Vette pump? I have one I'll loan you for SN testing purposes.

I appreciate that. Have you used one and if so how much vacuum was it capable of?

It's likely not what you guys are used to, but it worked well on my SB, BBC and Subarus (terrible CCV and sealing issues).In-Tech wrote: I'm curious for more details of this electric vacuum pump as well. What engine hp and size of engine/brand,etc. Sheesh I need to get out more.
Are you using part # 12554580?n2xlr8n wrote: ↑Tue Feb 20, 2018 8:02 am
I posted it here somewhere- I think it was 5-6", but my methodology was not the best. A started using them in 2003 when I saw them on many of the Outlaw 10.5 cars around here. Not having access to a dyno personally, the only thing I noticed was the plugs looked better (low 9 street car), and I it idled better.

...and they are cheap- both the pump and harness can be had from Delco distributors for less than $200.
The PN on my box is GM 24505066 air pump, 95 Corvette, but your PN certainly is a clone of the pumps I've used.CGT wrote: ↑Tue Feb 20, 2018 9:12 amAre you using part # 12554580?n2xlr8n wrote: ↑Tue Feb 20, 2018 8:02 am

24505066 is now discontinued. Your harness number is still good though. I may get a 12554580 and see what it looks like. I doubt it will pull the amount of vacuum that I'd want. But I can see it being nice for somethings I mess with.
The spacer is an HVH I recently acquired, the 1050 I just had jmark go through for a dyno carb for all of us to try. Neither one are specifically for special needs. Just set them on there to get them off the bench. I may test the dominator on it, but it will most likely have a 4150 on it for most of the tests. RPM will be the same as previously 3000-7000.

Actual dyno results ????
Sure. If my results don't agree with theory, go with the theory? Is that right? In all seriousness, she should be good to go.
1050÷128=8.2something ,, yep good to go!
