who is bickering? same tune and no timing change. asked and answered,
humidity change? no answer. Not gonna call anyone. just asking the question, and at some point you folks gotta accept that asking a question doesn't mean questioning the results.

I understood a pulley change , missed the blower change. re read. thanks

FYI air density variation makes a huge difference in both power, fuel economy and even aerodynamic downforce. huge.


https://www.brisbanehotairballooning...r-density.html

 

"The atmospheric pressure, temperature and humidity all affect the density of the air. On a hot day, or at high altitude, or on a moist day, the air is less dense. A reduction in air density reduces the amount of oxygen available for combustion and therefore reduces the engine horsepower and torque. For tweaking the fuel/air mixture, or predicting engine power, the air density is the most important consideration."

Installing and dynoing thursday. Looks to be 55* for a high with low humidity!

 

Better text me result k-dawg

 

I don't know what you want me to say. I cannot control the weather. The time is listed on each run, blower was swapped in 1/2 hour. I could not get the runs any closer together. That's what correction factors are for, which were used in this graph.
These results were posted and nit picked apart on Facebook. You know what I'm talking about.

We are friends. And i want it to stay that way. This was only re posted cuz it was asked for. That's why I simply said not gonna bicker about it.
It is what it is. Done and done.

 

What size meth nozzle will you be running?

 

Mcclure, looks as tho you changed from M62 to TVS while on the dyno?
Is that where the almost 20whp and 18tq comes from?
Im trying to understand without reading several pages back

 

He changed from a stock m62 to a ported m62

The other change was 2.6 to 2.5 pulley

 

someone has their ball sack in a wad

 

Ok thx

 

that made my day

The description for each run gives blower details.
2 runs stock 2.6 laid almost identical on top of each other
Next pull ported m62 w/ 2.6
Then ported m62 w/ 2.5
On the last pull (ported 2.5) iat2 only rose 10* start-finish


Only reason I posted it in here was blairwolf asked for a video/dyno of zzp s2 cams.

 

the only caution is the air density improved significantly for the last two compared to the first two runs. so....

 

fify

 

 

I want my TVS back, and I want it on my engine.

 

it improved so much the earths rotation changed

 

Can the cams still sound like that after you are tuned for them? I would maybe consider it when I'll build my head later

 

Yes. Mine was. Just gotta get creative.

 

Damn that idle sounds so nice haha! Might do it then...eventually...Too bad when we'll rev it won't sound like a big block hahaha

 

I remember the first time I heard a 440 spin 7500...
I was in awe.

 

haha. thats the problem with open air dyno's. Not saying your ported pullied blower did nt do just fine. It did. Good for you. But I am just saying that air density and humidity are big changes that affect power. Bigger than perhaps you considered, and 10 % change in humidity in an hour is a huge swing.

id1000s where a lil bit of a pain to fit right had to pull them out because one injector oring pushed past the injector cup

 

Anyone have pics on what you modify to get the dw300 fuel pump to fit
