I do miss some of that early low-end torque I used to have but the 'net' is undeniable.
I have yet to rev past 6400-6500 out of queasiness. The A/F ratio at 6100+ starts jumping around after being rock solid all the way up. Quite possibly I may be at the limits of this ECM... Or it's that restriction at the end of my exhaust steam... IDK...
But the power went right up to 6300 in a straight line, not curve as I expected.
I've found some Enkei racing wheels that only weigh 15lbs...with the tire that should put me at ~45 lbs. That should put me around 220+ 'at least'.
The future is bright.
On the downside - I was gonna race yesterday. Went to finally fill it up and then at the pump, the handle kept tripping after 3 gallons. I squeeze 2 more gallons out of it but then I looked under the car. Once again I was bitten by the crappy installer bug. They had installed a larger fuel pump and new fuel lines (in a completely non-stock patter that makes no sense) and I saw a leak where fuel was dripping from the firewall area in the center of the car. The drip was coming from multiple points so I believe the insulation is soaked. AAA took 3.5 hours to tow me. :/
...to be continued...

Here's my last dyno from 2019 after I put a notch across the bottom of the middle intake manifold for more top end...along with my 1st dyno from Friday and what we got to. The 2019 one is with my Weld 52lbs wheels. The current one(s) is with 56lb wheels.
At 5250 rpm (113.9 mph) there is a 30rwhp gain. Also note, in 2019 I was running E85 so that gave me 12 more hp. I have yet to convert to E85 and I'm running heavier wheels.

113.9 mph = 5250 rpm
Now that I look at the newer dyno, it looks like I may need less fuel starting at around 4600 rpm at that's roughly where it goes slightly richer first before jumping lean ... the computer's trying to target an AFR and is over-compensating then under-compensating back and for with a general trend towards being too rich... Probably need to do some fuel and timing smoothening with the 3D tool to improve the look of the graph from 4600 on up.[This message has been edited by lou_dias (edited 05-13-2024).]

Twas not to be. New lighter and slightly thinner tires spun a lot at the launch. Also missed 2nd approaching the first turn and ended up in 4th ... and stayed in 4th until just before turn 3.
All that said, it was still a 19 second lap which would be first place about 20 years ago.

Yeah... nah....?!
Rumble doesn't work in France.
My favorite trick is to put the car into 5th instead of 3rd!  ------------------

I've done that before too but I had the benefit of going against a slower car when it happened so I still won.
Here's all the races that day:
Mine is the 4th race in.

My car was down since the last race for a couple of weeks waiting for a new fuel sending unit.
Got it back just in time for the next event and made the rookie mistake of not checking my tire pressures...
First round was a bye round but still...
Some good analysis here about 3/4 the way through...

So we tried leaning it in this last run and started losing some power on the top end. :/
Ran out of time and had to leave.
I think I need to just keep throwing fuel at it as Rei advised me starting at 4600 and on.
I've definitely left some power on the table...but you can clearly see that lighter wheels = more power.
So basically you can go back and look at my years of old dynos and add 13-14 hp. But basically it scales with rpm... It looks like a 20 rwhp difference at 6200rpm...[This message has been edited by lou_dias (edited 06-28-2024).]
