New D-Tune Mag : Power Pages Modding The RX8 : Results
D Tune started modding the RX8 on their Power Pages section. Here are the results :
Baseline : 180 whp, 128 lb.-ft. tq Racing Beat Single Sided Exhaust : 183 whp, 132 lb.-ft. tq Racing Beat REVi intake : 190 whp, 134 lb.-ft. tq Racing Beat Cat Delete Pipe : 196.5, 134 lb.-ft. tq. Next issue mods = RB flash tune & grounding kit |
cool...nice find :)
|
So their intake gives 7 whp and 2 lb-ft tq but their cat delete pipe only gives 6.5 whp and 0 lb-ft tq.
Shocking results to say the least. |
remember that everything opens up more when everything is put together
|
does anyone know what the difference is in gains between a cat delete pipe and a super cat. I hear it's very little but wonder if anyone has expirence with this.
|
i had the super cat before i switched over to catless. there is definitely a power difference between the two, but difference aint much. all i can say is the numbers that d-tune magazine obtained from the dyno is pretty accurate because i have close to the same parts, but a little more and dynoed a little higher.
|
So they gained 16.5 whp and 6 lb.-ft. tq., seems better than I had expected based on the very pessimistic attitude most people seem to have towards power increases. I realize other cars may achieve higher gains from similar mods, but still, I had been left with the impression that those sorts of changes would gain barely any power and are really for cosmetic reasons and improved sound.
I don't know much about mods, especially for the RX8, beyond what I've read on this forum so I have one question. Can most people realistically feel the difference that 16 whp and small torque increase brings? Would you notice it day, to day compared to a stock RX8? |

The strange thing, Woods, is that those numbers don't exactly jive from a mathematical standpoint.

my friend called me last night at about 1am to tell me about that mag. I was goin to try and find it today just out of curiosity. I figure a Magaziene is usually unbiasd as far as numbers but then again ... you never know

I made a post about this in media but found this thread and deleted that one. I don't know where the name d-tune came, this is from DSport magazine, I picked up my issue at my local grocery store.

waiting for the nay sayers to come flooding in.

Re:
They are doing another test and tune on the RX-8 for RB flash and grounding kit, but that is not going to be next month's issue, but the April issue, next month is going to be test and tune on Evo9 with BPUs.
BUT, next month's issue will have coverage of Sevenstock 10 from September with pics, so be on the look out for that. |
How much money have they spent?

RB Race Muffler: $525 RB REVi Intake System: $336 RB Cat Replacement: $295 Total: $1,156 They were commenting about how good the results were for a NA engine. |

What they have listed is this:

The biggest issue I have with this read/upgrade comparison so far is that all these torque and HP numbers thrown around are really fairly meaningless without dyno curves; e.g., 15HP extra at say 8500rpm is nice, but 15HP over a good part of the rev range lower down too is far more interesting and useful on track or highway :uhh: maybe dynos are shown in the mag itself? Can't wait for the RB flash addition, and someone should tell them to add the Mazsport Ignition Solution. I think that pretty much would cover any available useful pnp NA power upgrades for all intents and purposes. |

I think that pretty much would cover any available useful pnp NA power upgrades for all intents and purposes. They have the dyno curves in the magazine. You just have to go out and buy it. Getting high horsepower in the low rev range from this car with NA mods are unrealistic. With NA mods on ANY car, on pretty much any motor they accentuate the base engine's power delivery. So if you look at our car's standard dyno, it is still a 9000 RPM engine that delivers power & tq. on the top end. The NA mods only increase that. |
If you have the curves can you show us?
|
Just got a photo on my camera phone of the article, so it is not really a great picture. You would be better off running down to the local bookstore & looking at the mag.
