Time Attack/Street Rotrex NA8 Numbers, Questions, & Insight...
Within the last few weeks I finally got around to getting my car dyno tuned after installing the Rotrex and some other supporting mods.
Wondering what some of you more experienced members think about the numbers and also why insight you might have as it comes to tracking a Rotrex Miata.
Car made 240WHP/189WTQ on a Dynocom.
Here's what's done to it pertaining to the power.
•235K STOCK BP-ZE Motor
•ExIntake Mod/KAInjection Adjustable Cam Gear
•Racing Beat Header(Ceramic Coated/Heat Wrapped)
•Unknown Catalytic Converter(looks to be higher flowing)
•Flyin' Miata 2.5in Catback Exhaust
•Rotrex C30-74(80mm Pulley)
•RX8 Yellow Top Injectors(425CC)
•DW200 Fuel Pump
•MS2PNP
•E85 Tune
•7500RPM Redline
Car is being prepped for Time Attack and HPDE and is still street driven to and from events as well as around town, to work, and to the mountains when I'm up to it.

Car has Flyin' Miata Crossflow, Fan shrouds(w Spal fans), and coolant reroute. It's also got a custom vmount intercooler setup and custom ducting to add efficiency to all the cooling items. Overheating shouldn't be an issue, especially since I'm on E85(it burns cooler than gasoline).

Boosting a stock 235k longblock is very bad idea. I wouldn't bother doing leakdown or compression test, just rebuild it. If you have the budget, add forged 10.0:1 pistons, rods and heavy duty valve springs. Not a bad idea to add either billet oil pump gears or at the very least a better crank damper and shim the pump for a bit more pressure.
