Thought I'd pass along some P5 NA numbers that will be improved upon shortly. The car has 4500 miles on the clock.
Ran a dyno check yesterday on my P5--Injen CIA, MagnaFlow CB--and came up with 104 WHP, 114 lbs/ft of torque. Crossover for the two was 5200 rpm. Three pulls came on a DynoJet chassis dyno at MAC Sport in Parker, Colorado. Great guys, BTW!
One thing that stood out--the engine went rich on all pulls in 3rd gear at about 3800, from a reading of around 14.2-3 to 12+. ECU is the problem. Doing some checking, I found that the MP3 chip should cure the problem. This means a leaner, more perfect mixture at higher revs (want to hit 14.1:1 or as close as possible throuhout the range to 6500). Problem is, find the chip. Dealers don't stock 'em.
Have an EssentialSPEED overbored TB and shorty bundle of snakes tuned header ordered, and am looking at a pair of MazdaSpeed cams--unless I decide to get the intake only and switch the stock P5 intake to the exhaust side. Some issues apparently have come up with j-spec exhaust/intake combo--lumpy idle, possible emissions problems, etc., although one of our clan says the pair are excellent performers.
I'll pull a dyno run after each mod is installed and keep you all up to date on numbers. You might find them valuable.
