Yeah I mean if you were running 14.2 at high loads forever then sure it may do some damage slowly and cause premature wear but it depends on many factors such as gas quality for one. But you won't "pop" an NA engine from detonation.
Yea... I know thats what he said... But 14's at WOT will pop the renny within a month or two.
14's at cruise is great but WOT is not great at all.
If he is not detonating then he is not detonating. 14's are not ideal but most Race prepped NA 13B's tune for mid 12's to mid 13's depending on the setup and get into the 14's on the track without issue and most OEM's (not rotary I know) tune for mid 14's at WOT.
But again, it depends on the gas he using, E15, E10, etc.
Oh and of course E10 and E15 are just labels and mean "up to" those percentages. But either way it makes calculating the actual ratio different and affects combustion and stuffs.
I'm just making **** up I don't actually know if 14's will pop it. It certainly wont be making the most amount of power. RBT is like 12.2 or 12.5 right?
yeah dpending on timing, etc. it seems most of the race NA 13B's shoot for mid 12's. But this is the rotary community so of course there are experts who say 13-13.5 is best.
Not any surprise that nobody else really picked up on the obvious. A variety of your mapping scales have been heavily massaged by the so-called tuner. You will need to select logging for MAF voltage to have an idea how far the MAF scale has been skewed to generate those high g/s numbers.

Daryl Drummond build
Original engine, no reman, with only 7K miles
All new seals etc.
Numbers were achieved on his engine dyno, not a chassis dyno.
Taking into account 15% drivetrain loss, I SHOULD be putting down 220whp...
My wallet is hurting, that's for sure. Took me 10+ months to save up for it while running on my blown motor...
I'm pretty excited to install this bad boy... Would definitely like some RB headers but I'm not sure my wallet can afford another $500 for only 4-5hp...
the inconsistency between dynos is much greater than most would lead you to believe, which is why I don't put any more faith in even my own than a wing and a prayer
the best dyno you will ever find is a 1/4 mile dragstrip at low elevation and an accurate scale to weigh on ...
Hey guys did several runs on my 8 on a dynojet, figured I'd post the results.
Engine - Mazda reman with 12k miles
Mods:
AEM cold air intake
Exedy hyper single clutch & 15 lb lightweight flywheel
Series 2 transmission with series 1 diff (4.44)
Gutted cat OEM midpipe
Raceroots 3 inch exhaust
Cobb AP running stock map with lowered fan temp, increased OMP rates, idle... (minor details)
Everything else on the engine is stock.
Plugs and coils are stock, and relatively new with low mileage.
Highest run was a 201 RWHP & 139 TQ, average of all the runs was about 197 WHP & 138 torque.
Now my question is do you guys think I'd be able to squeeze much more out of the engine with a proper tune? Average AFR at WOT was about 13.5 in the upper range.
Also I know that the power drops on the scatter plot when the valves open up, but is it just me or are they not as smooth as they ideally should be? Maybe a slightly carbonized sticky valve?
"power" mods parts list
AEM cold air intake
BHR D585 ignition coil kit
Denso Iridium spark plugs
Agency Power Dual resonated midpipe
HKS Hi Power cat back exhaust system
Buddy Club Racing Spec Condenser 2
Racing Beat 8lb aluminum flywheel
ACT stage 1 clutch kit
BHR/Griffon Radiator
Cobb Access port (omp rates and cooling fan temps only)
throttle body coolant bypass mod
made 177whp stock back 2012
2 years later 190whp
side note* Emery the guy who posted two posts ago made that 201whp on the K-phonix dyno made the same HP as my car on the dyno at Rotary Werks yesterday so the dyno reads a little low.
So you made 179WHP and then by the last run 190WHP? Seems legit.
no what happened was i was running a ignition map i had copied from a thread where people were discussing the proper dwell settings for the D585 coils, after i seen my first dyno set (176whp,185whp,183whp) i had left to reflash the car back to the oem ignition dwell timing map and returned to the dyno did another set of three runs (which for some reason i only record the last run off but you can see the results of on the pictures btw incase you were wondering one of the pictures are from when my car was stock.) and it made more power(188whp,190whp, 190whp).

We'll see if being on my phone will KILL the picture quality.
