Re: Senate Bill on Racing

isn't this the very definition of politics? No, this is a response to a real threat to the Performance Racing Industry. The OP did not make a political statement. He just made a PSA. I kind of suspect it was only political when you disagreed with it....that's for clarifying where you've decide to t...

Re: So electric may just be a passing fad again

I'm pretty sure if you feel the need to say "I know it to be true" then the post belong in P&R. For sure oil and gas production and distribution are heavily subsidized which distorts there costs. Same for electric generation and distribution. Years ago I did a womb to tomb cost analysis on a then pr...

Re: So electric may just be a passing fad again

https://www.understandingnano.com/fuel-cells.html I'm not sure how much of that is actually new or commercially viable, the latter being what we struggled with the most. for sure platinum/palladium and nano particles where in play at that time. To be reliable the systems got complex, which meant ex...

Re: So electric may just be a passing fad again

I believe Shell Oil Products U.S. says fuel cells will be the ultimate solution, but being in the fuel business they would say that, wouldn't they. I used to work on Fuelcells including automotive applications including GM and Honda. That was 2000-2002, they were all the rage until you tried to bui...

Re: EFI conversion - return line backpressure

Do you have a capacitor between the SS relay and the pump? Would it make any difference in reliability or how the pump runs? Ken I don't have a cap in there....never really thought about it but it does seems to make some sense. Normally when there is fuel pressure is very stable. I have the filteri...

Re: Welding cylinder head

I always worry about heat in an exhaust port.....so I thing anything you add needs to be attached to coolant flow which means a plate on the bottom to the port ids probably not a great idea. Plates in intake ports are fine, but I wouldn't do it in an exhaust port. There are some pretty small TIG tor...

Re: EFI conversion - return line backpressure

Return lines are at little to no pressure so its pretty common to use plain only rubber fuel hose which is pretty cheap. Edit: forgot the most important part.....since you are running a steel line that can handle pressure you really don't have a any problem as along the the return pressure is under ...

Far as I know, the only benefit is that the exhaust tuning can be better.
You can do a little better with the intake tuning too.

Got the design done, everything checked...they had asked for q coupke changes on my 18" set after they ran an FEA on it. The interesting part is the guy told me this order would be $370 shipping not the $370 he c...

Walked into the shop today and 12 year old's face went pale and took on a sort of terror....... 20191012_100758-resized-1024.jpg I looked at him, looked at the tool chest.... You ok? Nothing broken? or bruised? So just the little cut on your finger? How many draws did you open before it tipped over?...

Re: water brake calibration

I recently got an old go-power setup and was thinking about calibration too. In the manual they talk about a calibration arm that comes marked with what the load for the arm itself is....I don't have it of course. There are formulas to calculate it....or it could just be made symmetric so it adds 0 ...

Re: Sizing IR Carbs

In How to Build Horsepower; Vol. 2, David Vizard gave an IR sizing formula that determines the ideal choke size, which he says should be 72-80% of the butterfly diameter, preferably the latter: choke in mm = √ (CV x RPM/2600) , where CV is cylinder volume in cc and RPM is that of peak power.

Re: FrankenFerrari engine

The bellhousing for the dyno I found on ebay arrived and looks right...well a GM bellhousing on a ferrari looks WRONG, but it looks like it will mount the dyno :)
