So you have one on your R then? Can you provide draggy or time slips to show the performance increase? I do not care about dyno numbers….. what I find odd is that it’s nearly impossible to find documented acceleration times and a trap speed to show the benefit….IMO The doubters are clueless about the 100% uniqueness of a postive displacemnt supercharged (P/D S/Ced) engine.
The HP from a positive displacement blower is solely dependant on the blower displacement/internal pressure ratio and the pulley ratio.
You can make less power with a larger blower by simply pulleying it down to move less air than the smaller blower.
You can make the same power as a smaller blower by running a pulley ratio that moves the same amount of air.
You can also up the boost and make hundreds of HP more than the smaller blower could ever possibly hope to make.
Forget about headers, exhaust, all of the normal stuff you think of to make power on non-PD S/C engines. The P/D S/C alone determines how much HP is made by how much air it moves. Everything else is secondary or tertiary at best.
The only 2 things that truly matter for performance on a P/D S/C engine is 1) pulley ratio and 2) do not starve the intake side of the blower. Get big intakes, air filters and T/Bs to maximize power. Exhaust side improvements are nearly meaningless compared to just upping the blower speed a bit more.
The larger blowers allow you to move more air with less input power and less ouput heat (ie more efficiently)- so if you want to turn it up, the larger blower is always better.
Seen this but have yet to see any measured performance comparisons to stock…..
I kind of remember seeing them dyno it before and after and just bolting the wipple they did gain a substantial powerSeen this but have yet to see any measured performance comparisons to stock…..
But, "draggy"?I don't know, but would expect around 27% more power to show up in any time elapsed comparisons <sarcasm>.
Draggy times are the new 1/4 times for those that don’t have access to a track, can do it anywhere and is very accurate and accepted in the car/truck world. You must be living under a different I k if you didn’t know that.But, "draggy"?
WTF is the NOVA guy's obsession with this?
