I completely forgot about posting my graph up. Sometimes I'm not the plumpest bean in the can.



This dyno was from Dec 30 '06 at Redline Per4mance in Arlington, Tx. Dyno was a Dynojet 248C, I think.



The specs on my car at the time:



- Turbonetics 60-1 HIFI w/ a 0.96 A/R P-Trim turbine housing

- Running approx 24psi of boost on a combination of 70% 93 octane fuel (via the Haltech E6K system) and 30% methanol via the Alkycontrol.com Alcohol Injection system

- The leading and trail-split advance were 16* with a 7* split

- Stock top mounted intercooler

- Half-bridgeport engine built in Oct 2004 using 3mm Rotary Aviation apex seals

- Stock NGK plug wires, NGK BUR9EQ's all around

- 720 primaries, 1680 secondaries, twin Walbro 255lph pumps (with 1 disabled), 40psi base fuel pressure, custom -8AN and -6AN lines w/ full parallel setup and aftermarket FPD (Marren)



The motor misfired up in the mid 7krpm range due to running too rich (just richer than 10:1) and cracked the front plate's dowel land (older cast S5 irons; not reinforced) and puked about 4qts of oil on everything inside the engine bay and hood as well as all over the concrete floor, of which yours truly got to clean up...



The run was done in 3rd gear. Here's that run's Haltech datalog:

wow https://www.nopistons.com/forums/pub...IR#>/blush.gif look at those curves

Wow, you really did that with a stock tmic, thats impressive, sorry about the dowel pins.

i've never seen a rotary crap out from being too rich. hell my fd ran below 10 afr the whole time

2nd gen block, older one, not reinforced around the dowel lands, was running in the 11's:1, hit real high RPM's, was sitting at real rich, stuttered the motor, cracked the dowel land.

dam those stock little top mounts flow decently

Impressive



rotaries don't like extremes

TOO rich can be as bad as too lean

unburnt fuel sticks to faces of rotor and can cuase all sort of nasty thiings
