Yeah I might be down once I change out my plugs and little things. I put 360 to the wheel with my car leaning to 13 or so Afr near redline. I was about to schedule a dyno with hps but if you can get a deal, I'm down.

Yeah, Steve Kan tuned it. I hope that my turbos aren't stock twins. The more I dig into the car, the more modifications I find.

I hope they don't blow, its been 3 track days and 15k miles. The chart says 14 but my gauge was reading 12psi.

Oh, this was a dyno when I did it with a few friends. I'm down for the dyno when I get my car ready. Just need to sort out the suspension before my next track day.

Lmk if you guys do a local dyno day, wanna see waht my twins are putting down

Some insight on dynos and my thoughts..
Every dyno reads different! They say that dyno dynamics, dyno paks, Mustang read lower than the popular shop standard Dyno jet. Ive heard people say anywhere from 10-25% lower. Its all "hear say", there is no proven formula to compare different dynos. I know in Japan dynapaks are standard. my personal favorite dyno is the dynapak for its accuracy and precision in tuning. Ive seen alot of people compare their hp online, and honestly its not accurate. A few factors to consider include the make/model dyno, settings in dyno, calibration of dyno, air temp, altitude, moisture,time of day, spark plugs, fuel, etc. My honest opinion is that a dyno is a tuning tool to tune your ecu, and maximize your vehicles performance! When tuning your vehicle, continue to stay on the same dyno, at the same shop to help keep track of your mods and vehicles hp progression. Another thing is its easy to crank up the boost +15psi on stock twins and laydown a big number, but how long are those turbos going to last? Or maybe crank its up for one pull for that nice dyno sheet to frame on the wall :) haha If you want to compare hp acurately, it has to be on the same dyno, and same day/weather conditions. Theres alot of factors.. Use the dyno to measure personal gain on your vehicle.. -Dan |

i agree, but i'm not sure about the dynapack dynos. i'm skeptical because the last one i used i turned out 485whp on a GT35R FD at 18psi. maybe i'm that good, maybe the dyno reads higher than the dynojet i usually use, only way to tell would be to do a run of the same car on each i guess.

That's impressive for 91 and with no tricks?!(meth/water injection) what computer?

the dynos seem close but i haven't really noticed that it was far out of line with the dynojet, if anything they were very close with the dynapack possibly reading slightly higher. in the end it's always about the calibration of the dyno, some of the engineers/installers that set them up don't put in the proper calibrations which is where a lot of these variations come in. |
Any updates, seems like like the sequential swap didn't go to well

280whp 10psi isnt that bad considering you have a stock port motor. I bet youll be ~300whp at say 11.5-12psi. I would personally be happy with that.
Can you post up all your mods? |
Hey guys. I have been MIA due to work. Here is the new plan.
1. I bought new injectors and I will be changing out the primaries to 850cc 2. I bought a greddy boost controller and will have the car street tuned up to 14psi. I will most likely only run the car to 12psi most of the time but just for those moments where i want a little more power, I will have the option to crank it to 14psi. 3. I will most likely not have the car tuned on the dyno this time. Unless someone has a dyno I can use to make one run to see how much power it will be putting out lol |

Can you post up all your mods? Well, after doing a lot of reading and from the responses from the guys on this thread, it really comes down to running the car on another dyno to compare the numbers. I am not sure if I want to do that and put my car through that abuse again so I think I will be happy with a street tune for now. The car is already tuned to 12psi so all the tuner said he needs to do is add more fuel and mess around with a few things to get it boosting at 14psi safely. Here are the mods on the car: Non-Seq conversion Peter Farrell intercooler Fluidyne radiator downpipe, midepipe, rb catback New injectors (primary and secondary 850cc) Fuel pump upgraded to supra denso pump 30k mile stock turbos Greddy boost controller Power FC Suspension: R&R springs on tokico shocks Interior: stereo head unit is removed to reduce weight hahahaha (this is my most important mod. I actually bought it that way) |
I just had my car tuned with Nelson. It's 12 PSI and around 255 WHP. Here are my mods below. Should I ask him to crank it up?
Apex-i PowerFC with Commander Apex-i AVC-4 Boost Controller HKS Twin Power ignition Greddy under drive pully kit Peter Ferrell air intake with air dam Peter Ferrell stock mount intercooler (Medium size) Koyo Radiator Bonez 3" down pipe Apex-i N1 dual exhaust Dual Earl's 25 Row Oil Cooler 42510 -10 AN ACT Clutch ACT Streetlight Flywheel Non-Seq mod Rat's nest removed Air-Con removed Aquamist Water Injection Forgot to mention previous owner claim that Steve K tuned it to 290 (I assume it's WHP) |

Was if just rebuilt, or does it have a lot of miles on it? |
Engine have about 20k miles on it. It was replaced at 65k miles with Mazda Manufactured engine. Car only leaves the garage for track days so I barely put maybe 1000 miles on it a year. I guess I'll run a couple track days and see how it feels.
Anyone interested in attending Speedventures 5/3 - 5/4 Auto speedway event? |
street tuning is actually more abusive than a dyno tune is since the car can rest easier after a pull which puts less stress on it, it's all just crammed into a smaller timeframe though.
i prefer street tuning since it is the most accurate method of tuning but it is less safe due to driver focus and high speeds which always add a chance of something going very wrong and can take quite a bit longer depending on your surroundings. if it's my own car i do street tuning only, if it's a customers car i will do dyno only because it's cheaper for them(just driving to a tuning section of road can take 45 minutes each way plus hours of actual power tuning, plus the added cost of the liability of getting an expensive ticket or thrown in jail). if they want the best economy and power mixed then it gets dyno tuned followed by a normal driving street tune(for those who want 20+mpg). i don't do power street tunes anymore just because it takes 1/3-1/2 a day and has other liability factors. |
