You’d almost think it would be like a tornado affect…. Riffling through the underside!

Huh ?

Many of the roots blowers have the pie shaped opening at the front also.

Hardy har har! 😂

Interesting video -- too bad there isn't one of a blower.... Now add an intercoolers into the mix and i can imagine how that affects the ability to carry fuel in suspension also...

It would be cool to see the data that OEM car makers have. I bet they have researched the Chit out of this considering the performance/ gas mileage and emission targets they have to get to.

What ones? I’ve only had weiands, b&m’s and blower shops 8-71’s. Just curious what the method behind it is also.

Mercury makes this work,




The roots I`ve had were more like this .

Mother mercury tuned engines really rich for a long time. I’d bet they knew about fuel distribution issues and fattened them up until the leanest cylinder was safe.

I would be leery of a tuner that is setting your tune off of one tailpipe O2 sensor.

When engine masters looked at cylinder variation they would sometimes see multiple points difference across cylinders.

Dan if you can stomach the complexity, port injectors and pre blower injectors would be really cool. The whipples seem to work better wet, my theory is that effectively tightens them up a bit. It could just be due to evaporation though.

My last week of work as an employee is this week. My first entrenpenurial endeavor will be to design a full length primary tube extender for the stainless marine manifolds, I’ll probably work up a 4 port O2 sensor plate too. Probably would only be needed for when you are tuning, then you could lock it and take all of them out. Maybe just keep one permanent afterwards for safety.

Correct me if Im wrong but if you have an injector failure in direct port injection that hole has no help and immediately goes lean ? boom.......... the TB injectors in the Whipple should blend in and possibly save it
