So, all that "low RPM power" that the PD fan boys keep raving about produced nothing but tire smoke with Nitto NT05R tires on a prepped track. Exactly my point.
If you're going to spend the time and money to add a FI system, buy a superior front mount twin turbo or a centrifugal.
They'll get better traction in the low RPM's, make more power everywhere else, and a centri will put down the power better with linear boost delivery.

If there was a centrifugal on the car I wouldn't have been running 10s...
I have plenty of experience with centrifugal SCs (
www.toohighpsi.com) but they are not the right choice for a heavy car with a stock auto transmission. I have a pretty good background with every power added out there and lack of low speed torque would not be doing me any favors no matter what you think.
With the PD blower, I can always pick the launch that I want to have, simply by the RPM at the tree. On the factory street tires at the track, launch at idle with a swift roll to the floor allows a great launch without wheel spin. With a tire like these nittos bring it up to about 1500RPM on the converter and I was going mid 1.5s 60fts. With a set of MT drag radials and 2000RPM at the tree (about the most you can get with the stock converter against the brakes) probably drop into the low 1.5s or even high 1.4s.
I will always take all the power under the curve that I can get - I can't say that I've ever complained about too much power and I've always found a tire that can handle it.
I am a drag guy, so I don't consider a Nitto anything to be a good drag tire (especially on a 20" rim), hopefully I'll have a set of MT or BFG on a smaller diameter rim with more sidewall next time I get the car out.
I'm looking forward to the performance of other kits that are arriving on the market, but rarely do we get to see a stock vehicle SC only ET. For this car it's just a starting point - I like to go fast, so I guess we'll just have to wait and see how those "not possible PD" 9 second predictions that I keep seeing hold up...
