We did tons of roll-ons one evening during a 40 mile drive to dinner starting at all different speeds, and the results were always the same, NA lost every time.
If the roll on started with both cars near peak RPM point, there was an instant where they were equal, then the shift happened and it was all over at that point. The PD blower made so much more power at the lower RPM, the NA car was left looking at taillights until it could reach max rpm where it would hang on a little before another shift which put it even further behind.
We covered this "Power Under the Curve" in another post recently and the plots there are quite simple at showing the benefit of making more power everywhere (traits of PD or nitrous), not just at a higher RPM which is normally the case with NA or Centri SCs.

I don't believe that for 1 second..
Your telling me that just a bolt on Maggi at stock level with no meth or headers on 93 vs Cam, heads, headers and e85 wins every time.. If that is the case he needs a new speed shop, needs to learn how to no lift shift, or it was about 55 degrees out!
You be crazy not to take all motor 550 rwhp over 550 on blower rwhp. I guarantee the torque on all motor w e85 would be a lot more than the procharger.. probably equal to maggi since we know from testing e85 raises torque.
like I said the most of the fuel system cost would be done... then do a FI.
I think everyone has this big image in there head that SC is the answer and they like to boast that they have one.. But the stock level is easily out grown especially in 100 degrees no matter the system.
It is the cheapest power for the dollar other than NOS, not many discuss the downsides... you have newbies that read the forums and want all this power and never are advised about upgrades after the blower in this case... a better fuel system... or the cheaper more dangerous route of meth, or better heat exchangers and tanks for PD guys.. and so on..
If we are getting nit picky do the real turbos over that belt driven turbo.. they make the most power with our inadequate fuel systems.
This dyno is from 6th gen post in engine/bolt on in our forum ported TB, kooks and e85.. Imagine if he had heads and cam... think of the torque!
