The prototypes have been dropped off at the tube bender and I am now awaiting the 304 stainless bends so we can do our fabrication of the full stainless steel headers Just need to get in touch with a collector supplier now. ---

We need 1/4 mile times. If I remember (too lazy to check now) the guys at spl parts got their NA 350z to a low 11sec 1/4 mile or some shiznit like that. ---

yea 12.8 im not sure what tires but i think it was mostly suspension work, that car isn’t making that much power. I’m confident we could get our roadster or race car into the low 12s rather easilly on drag radials ---

Sorry, but I’m confuzed; “every gear would result in exactly the same power”? how would this be possible? Each gear before 5th(asuming 5th is a 1:1 ratio) would be a power “multiplyer”. Does the dyno know what gear you are in? Calculating the gear ratio every time? does the dyno know the final drive? what happens, lets say, if your in 4th? Im not an expert on dynos, but am very curious about their power ouputs. As after my winter mods I would like to know the acctual wheel hp output of my own vehicle. Thanks! ---

It’s just calculated… everything to do with horsepower is math… it’s not a direct measure of power (torque is) technically the torque that the dyno sees is affected by the gear ratio (part of the reason you use a high gear… so you dont break shit) but the computer makes up for this… it knows the RPM and it knows the final drive and it knows how fast the hubs are spinning… those are all of the inputs it needs to give you an accurate number. I’m talking out of my ass slightly because I’m not a pro by any means Dan will have to give you the final word on this one ---
