Would anyone be interested in an roots blower manifold if I manufactured one?

I see. So, if that's the case, then you would prefer peak power (let's just say 650 RWHP), all at 1,800 RPM?

If your car can dead hook from a dead or barely rolling stop, then this is fine. However most people who are running FI setups have enough power that traction is an issue. Sure, if your car has zero traction issues then power off the get go is perfect. For the rest of us, you don't want more power until you have more traction which does not happen until a faster MPH and as a result a higher RPM band.

That's great. Like I said, for those where traction is not an issue. Most people I am guessing would be more into street use and most probably don't run around on slicks. Even with slicks, and full race suspension, I still had traction issues. Traction issues that would have been much worse if I had even more power down low.

Look, I don't mean to say "you are all wrong" here. Just giving my opinion. Again, I am happy to see new things brought to the table for the LT1, even if it's not something I would be interested in.

My car would be like my truck, WOT is 3k rpm

i never said that yours saying we are all wrong ... its just that there are fixes for traction issues that is all

Well with full drag suspension and slicks, and still having some traction issues, without reducing HP there is not much else you can do. That's my point, and why IMO that roots style blowers like this would not be preferable form of FI. Centrifugal Superchargers or turbos would be the preferred route, or even nitrous you can hit once you have established good positive traction.

@firebird_1995 designed his own system. Very impressive but I remember him saying it was a violent hit.

Yes it was. From cruise vacuum pressure to 12 pounds of boost in half a second as recorded on data log

Whipple done yet? Then we can test to see if 18psi hits quick

It's ready to go. Still working on a bracket to hold the tensioner and idler just right so you can use those $15 Goodyear gatorbacks vs a custom belt.
