Def's Dyno Runs, A learning experience Options

[Defgeph]

Hey guys,

I went to the dyno this weekend to find out what numbers I'm putting down. I came out very impressed. I was thinking along the lines of 230 hp to the wheels.

New Dyno Video 10MB

At 17.5 PSI, I put down 246HP and 261 TQ. Just insane.

Look at one of my run files below. I am still having trouble tuning my boost controller. You'll notice that after 4,000 rpm I have very strange spikes in boost. The theroy we have is, the controller is opening and then closing my waste gate door over and over after 4K. In the next few weeks I'll be tweeking the profec to run a constant number, then go back to the dyno. I believe I can squeeze out a couple more horses once this thing is set properly.




If you have any suggestions, I'm more than happy to hear them.

I'd like to again thank Manny, Jenn, and Dustin. With out them I would'nt be sharing this information with you. Again guys thank you, anything you need I'm there.

6GC. Without this place, I wouldnt have what I have. A thank you goes out to you as well.


Thanks ,
DEF

finally, instead of giving me a hard time, we are talking about the topic i was trying to bring up !

now what about the bigger AFM and the upgraded fuel rail. if what chrisD said about his sparkplugs with an upgraded rail is true, then this could also have something to do with the a/f ratio. when we put these huge fuel pumps on there, the fuel has to go somewhere. since an FPR is just a spring loaded valve, preset at one tension, its probably going to react differently when it has more fuel to deal with. .......THIS IS MY THEORY/OPINION ONLY. DONT CRUCIFY ME

the other thing we know is that the AFM is a different part number and is bigger. why did toyota do this? does the afm have a better resolution? or is it just bigger so that it can flow more air?

ART, YOUR A NOOB!!! hehe j/k

Is ChrisD running the stock regulator with an upgraded pump? If so, I think your right. There are a number of swappers, like me, who could not use the stock regulator because it allowed for a HUGE base fp. If he has a properly tuned afpr, I think there is something else going on.

The regulator keeps the f/p constant to the injector so that the injector injects the exact same amount every time (at a given load and rpm). If working properly, the fpr does not allow more fuel to "get by".
