Ok, here are my dyno results. I know 95 pct rx7 owners can care less but here it goes anyway.
I did my first run a few months ago at same boost level. I did 266 @ 12 psi. Here is that chart..... |
Here is with a MP, injectors and fuel pump BUT I boosted at the same as the previous, so it should not be relevant to the injectors and FP.
|
I should point out on the graph above that has 315.8 HP, it base lined at 298, he did timing and stuff, got me to 315.8. so the difference between a MP and HFC maybe be about 30 or 32 HP on my car at same boost level.
|
and my tq and boost. can anyone figure out my torque from this? I reasoned its about 265.
|
Interesting, I didn't expect it to be that much. I figured 15hp max difference.
|
wow. good to see some ppl get the #s... :bigthumg:

The turbo cars respond so well to mods unlike N/A

I am not sure that all of the horsepower you found can be attributed to cat vs. mp. If ytou look at the 2 graphs, the second one with a new fuel pump and new secondaries is a much smoother graph. I would imagine you gained some HP due to proper fuel/timing.

Another interesting note...
It appears that the first dyno was on a Dynojet and the second one was on a Dyno Dynamics... I think there is a "correction factor" that we need to apply here to take into account the differences in the equipment used. |

I think there is a "correction factor" that we need to apply here to take into account the differences in the equipment used. Ok, The first chart is a dyno jet which was done in 4th gear. A dyno jet ALWAYS shows higher #'s than the dyno dynamics will (I dont know why). The 315.8 is a 3rd gear # and it is correct to approximate what A dyno jet would show. I kinda left that out cause its difficult to explain. Before the correction my #'s were 260 HP with the MP, he did tuning and brought it to 276. The Fuel pump and injectors should not have anything to do with the #'s. I ran 12 lbs of boost and if you look at my A/F its not much difference from the first dyno chart. |
on your pfc... what is your primary and secondary % wastegate duty cycle numbers set to get 12psi with a midpipe?
