There are in car tests going on now. Will know soon.


So when are these in car tests going to be done?

All these tests have been done years & years ago by many people including myself.
If anyone want's to know what works better for a certain application,all they have to do is ask here & they will get an answer/s.
It's just that easy.

For an example,250 CI L6 ,a guy has 11:1 compression 230 duration cam @ .050" .550" lift on a 108 lobe center
3000 rpm stall 410 gears. 3000 lb car. 500 CFM Edelbrock AFB or AVS carb
That person wants to know what intake manifold would work better for racing 1/4 mile ,an Offy or a Clifford.
Just an example:
Another guy has a 194 CI L6 has 8.3:1 compression,cam is .450 lift,duration @ .050 is 200. 323 rear gears, stall is 1200 RPM PG trans,car weighs 3500 w/driver.
Main concern is gas mileage,& wants low end torque,, rarley will see above 2500 RPM, daily driver.It's just a driver,wants to know what manifold is best for him?
