Not sure what kind of power it takes to do that in an AWD but I’m betting close to thd 650 it made on the first pull.

Now I have an uncalibrated maf still so I understand the numbers are inflated about 10% or so from my calculatoins but DSMLink was showing: > > 4761.8 hz > 791 gm/sec > 5.61gm/rev > > Would a single walbro be able to support that? I can tell you it did. Not only that but when I asked around on the Link forums about Walbro #'s I found that I wasn’t the only one making close to 700 on a single pump there were 2 or 3 other guys on that forum alone that made more power than I did on mustang Dyno’s on a single pump without nitrous. Kurt, you know I like you, but 690 on a single walbro even at 13:1, holy fuck. That second pump had to be working to NOT lean out more than 13:1 at 42psi. When I kill a single walbro it goes lean and lean in a hurry and I’ve yet to go that much north of 30psi. I can see 700 wheel with a boost a pump, you sure those guys weren’t using that? --- _[View the full topic](https://forums.speedlife.net/t/first-700whp-tune/205049)._
