Def's Dyno Runs, A learning experience Options

[lagos]

nice numbers and VERY nice air/fuel curve. i wonder how much your new fuel rail has to do with that?

ps. you need an mbc..lol

I really wish now that I did a before and after with the rail. The MBC sounds tempting

change your plugs and check them after letting the car idle for a few minutes. if they are not crazy black (like they normally are) ,then i would be willing to bet that the rail has something to do with the a/f curve.

the rail has nothing to do with the curve.
all the rail does is lower the pressure drop across the rail.
if anything, it'd make it richer.
its all in that RC ecu.

i remember ChrisD from ctech telling me that once he installed an upgraded fuel rail, his spark plugs no longer fouled up like the do on every swap. so thats why i was thinking it might have something to do with it.

@ 20psi I thought my wheels were going to fly off my car heh.

you really should be running any more then 15 on a ct26.

time for a turbo upgrade

gt35r should do the trick

nice power

I'm not doubting ChrisD, but I have never fouled out one plug with my swap. So, I dont really understand what you mean ?

Did you ever foul out plugs with yours ?



Thanks for all the complements guys.

BTW GT35R is a little to much for me

[lagos]

if you put in fresh spark plugs into a 3s, and just let it idle (not even drive or boost it) for about 2minutes, then take them out, they will be totally black. chrisD said this dosnt happen with an upgraded fuel rail .

very nice run jeff and great video

that RC is defenitly beating the expectations

ill be posting dyno numbers with that turbo sometime in the summer

[Batman722]

actually those are REALLY great #s
we just NEED to get that boost controler set PROPERLY.

[presure2]

just for comparisons sake, heres an overlay of jeffs best run VS a bone stock usdm 95mr2T
i think jeff has a slight advantage...

[Defgeph]

I said whoa! When I first saw that run file, the difference is like night and day.

[lagos]

now look at the mr2s "tuning". dont you think there is something wrong with that? i cant understand how toyota could tune a car off the scale ritch and sell it like that. there has to be some type of issue going on. that car looks like it has no factory tuning at all.

[presure2]

actually, art, thats pretty typical of what you see outta a usdm 3sgte.
that specific dyno chart is one that is used all over mr2oc, and was given to me by ken blake, as refrence for my runs.

[presure2]

heres a copy past from KO racings website, its a street brawler VS stock setup, stock is the red graph, you can see its virtually the same as the one i posted.

[lagos]

what im tring to figure out, is why is it off the chart ritch? whats the problem thats going on here? is it the afm flapper door? is it from an upgraded fuel pump? could the factory ecu tuning be that horrible? i cant imagine the toyota engineers tuning the motor on a bench dyno and making it that crazy ritch. if anything they would want to lean it out so that they would sell more cars by being able to post a better mpg number. it almost seems like there is a common problem with all the cars, that toyota didnt intend to happen.

Yea, the A/F on the MR2 is wacky. Maybe Toyota just wanted to be way over-safe on the motor, but thats just crazy rich.

And Jeff, thats a beautiful dyno run. That thing really pulls now, my personal a$$ dyno agrees with those numbers as well.

[Defgeph]

Thanks Corey, anytime you wanna chill gimmie a call.

[Silver94CelicaOw...]

Anytime. I really want to see what the thing is like in the day, I think i've only ever riden in the RC at night. We're stealth like that.

I'm going to see if the weather is looking alright for tommorrow, I'll call you.

there IS no problem, art.
