How much is a rebuild?

yea but a wideband will be there for when you get future mods and seeing as how the temperature changes on how your car is running id rather know what my air fuel is before mashing the pedal to the floor

ill look into it

Did you have to pull timing to get that boost?

Anyhow, if that's about average then I am curious why the STi did lower than expectations? Most (I think all actually?) Mustangs notoriously read low. We all know that but that's very extreme if that dyno has no setup/operator problems.

Also, interesting the AFR issues with the flashed ECU. One of the very reasons why I will never go with any flashed ECU. Why didn't you know it had WOT issues before you spent all that time and money going to the dyno?

I dunno...

I'm glad your ProBoost MBC is rock solid. Unfortunately my Forge currently is broken and has to be replaced. I'm sure John Estrada who's been tuning cars for 10 years knows what he's doing, so I entrusted him when he tuned it to 30psi. I have a Forge WGA also, Shawn, which allows for the high boost with (what is supposed to be) no problems. There was no operator error, the MD we ran on was just (for whatever reason) calibrated very low. The owner of IMP and operator of the dyno (Joe) even told us that. John (JestrTuning) said the correction from IMP's Mustang Dyno to the Mustang Dyno that he operates on out of his shop in Orlando, FL is 55%. Take it or leave it, that is what it is. If anyone has a problem with the numbers or correction factor, I urge you to goto IMP and put your car on the rollers and prepare to be embarassed. Travis' car wasn't "lower than expected" he just has a boost leak which became obvious when John maxxed out the boost and showed this to him that his car would not go past the 16.5 mark no matter what he did. Time to keep reading to see what I have to post next.

The 2 IX's that went before me with basic bolt on's were making 160/160ish.

1) Your sig is a fucking lie. Period. Similiar to how you lied before, your car didn't make those #s. Sorry, lies really annoy me.
2) Dyno correction #? Please. You make what you make.
3) Yes, you went to a lower reading dyno. It does not explain your car's #s given your running more boost from factory, supposedly some ECU flash (that is probably suspect given your AFR), and your catback, intake, etc... Either your car made that power or that dyno and/or operator have some SERIOUS problems. Dynos should be used as a tool for TUNING. If your going to get #s, they should at least be somewhat accurate.
4) I WISH your car had oil leaks so you would have an excuse to replace the vicosity destroyed, gas filled oil that you currently have in there right now from that disgusting AFR that could have caused BEARING damage (Read: Not turbo bearings!)

Argh. Sorry for the rant. I like ya man just have my own pet peeves.

EDIT: Fixed typos.

1) if you think his sig is a lie, please take it up with International Motorsports or Jestr Tuning

2) see 1

3) using the dyno as a tuning tool, we were able to establish that Travis has some vac/boost leak issues. John maxed out the boost on the bcs and the car would NOT go past 16.xx psi regardless. Once his leak is fixed, I'm going to finish the afr's for him.

4) see 3

that was the stock ecu vs the cobb tune...

cobb tune vs open source tune

and stock ecu vs open source...

I said my MBC was rock solid at lower boost. I have no idea how it would perform at the boost level your running. I basically said it just to reassure the MBC haters out there.

Yea, I would not have the balls to go that high on boost. How many pulls did you make? Even with VP C16, we slowly made 1PSI increments making sure there was no problems. I thought it was a dyno day so I didn't think you could make many pulls so that's why I thought it would be bad pushing boost that high with just methanol unless you had some leaded?

Again, there is NO correction # on a dyno. Is this ricer land? You make a pull and you take what you get. It sounds like the results are not anywhere close to reality given that 55% stat.

That place is definately on the stay the hell away from.

Again, it's complete bullshit. Anyone can see that you both didn't make those #s. Dyno operators or users don't juse estrapolate a correction # and apply it to the results. The dyno sheets says XWHP and XTQ, then that's what you make. That other shit is left for CarDomain or MySpace.

What's next? Do we change the ET based on what we would have made if it wasn't 85F out or we didn't miss 3rd?

right so i have the worlds only 188hp modified sti... and justin has the only 11 sec potential 234hp evo anywhere

as i said before... once we get the boost issue sorted out and justin gets his new MBC we will be taking a trip to see Al Friedman (dynoflash) in CT to get pulls on his dyno and such and you can suck me off when i come back with numbers ABOVE what the corrected numbers were. all dynos are not created equal....shawn as i said before.. you put down 576 or so at pampena correct?... you wouldnt have made 425 on the MD yesterday. does that mean u only have 425hp... no.. it means the fuckin dyno is calibrated to shit. simple enough

Celtic1982citleC · #42 (**permalink**) 03-18-2007, 04:02 PM

Shawn, this was NOT a dyno day. It was a Jestr Tuning day @ IMP. Lots of pulls for all.

If that's what the dyno said, then that's what you got. I've never heard of anyone just adding a % to it and claiming they made that amount.

Ok. I heard it was a dyno day (A lot of people with 2-4 pulls each conseq.)

Just saying for me, that's a way too much but STi/EVOs seem to be a bit more forgiving. Anyhow, I am a worry fart

What was the increments going up? I assume no drop offs on the graph (Except your boost curve was crappy due to the MBC) or any other issues so you kept going up?
