Is it possible with stock turbo, stock cams, no alcy/meth and 93 octane? What do ya think. Can it be done and what would it take. I am assuming on a dynojet for clarafication. We have already seen 360-378 by a IX with simple bolt ons. Can another 40whp or so be squeezed out of the IX?

Discuss..

Those numbers were with race gas, I believe.

 

No.

 

You're going to need something to up the boost.. race gas.. meth.. etc..

 

so what do you think the max is? I have yet to see anyone dyno a IX with any more mods than a TBE, MBC, Intake and flash. Are the other things (FMIC, uicp, licp, porting, tubular o2 etc) worthless then, or would they provide legitimate gains for the money? I was wrong about the original numbers I posted, that was race gas (thank you warrtalon). I have seen threads stating 330whp (mbc, flash and 91 octane) and the guy in Puerto Rico that put some nice numbers down.

Basically what I am getting at is this. Should a IX owner like myself purchase a TBE, MBC, intake and get a custom flash and call it quits until cams are availible or do a turbo upgrade? It is starting to seem like the usual VIII 'stage upgrades" are irrelevent to the IX.

Girlie

 

Honestly I have no clue. Time well tell.

The mod path should be similar to that of the VIII's.. MBC and TBE are probably two of the best.

If it was me I would start with a 3" TBE (no cat), MBC, 20G upgrade, custom tune, maybe a drop in filter. I'm not sure about cams on the IX yet but they were a huge improvement on my VIII.

I guess it all depends on what you plan on using the car for... what type of racing etc..

just my .02

 

I have a conservative tune from Vishnu w/ TBE and HFC on 91 octane w/ 295 whp on a dyno dynamics. Conservative means 10 or so whp left on the table perhaps.

Add 93 octane into the mix and theres what, 10whp? I have no idea.
Add an intake and tune acordingly? 8whp? Again Im not sure.
test pipe is maybe another 10 whp?

Running out of HP on the way to 400 whp me thinks.

 

Maybe, but with straight pump gas I'm not sure.

 

Here are a couple of ideas I was pondering.

According to Al, the IX seems to be a little more resistant to knock. Probably from the redesigned coolant passages in the head. If one were to install a ported/coated mani, turbine housing and o2 housing could the tune be even more aggressive (more timing per say) due to the reduced backpressure and better thermal qualities of the coating thus supressing knock even further. On the other hand, could one run bigger injectors and possibly more boost, while still using 93 octane? Or even a combination of both.

Girlie

 

Injectors won't help, but the ported/coated bits will probably help to allow you to run more boost on the same octane than otherwise. I will be testing this here in the next few weeks when I get tuned after the addition of the Buschur ported/coated mani/10.5 and the Ebay O2 that Dave is sending me in place of the ported/coated stock o2. I will surely provide detailed results after Al tunes me.

Regardless, you're still not really going to be up to 400whp without cams or a fuel help (race gas or meth). I'm also not sure what the real goal is...why would you NOT do cams when available? That would probably be much easier and more cost-effective than drumming up alternative, expensive methods that might eventually squeeze enough power ot approach 400whp. Btw, you coming down for the tuning session or not?! That durn money still delayed?

 

400whp on stock turbo it would be difficult without running race gas or something to boost up that power. I would say that it would be a very impressive thing to achieve that. Lets wait few months until more parts are available for the IX .

 

It is not looking good on making it down on the 16th/17th. I still have not heard from my HR department, so there is little to no hope that I will have my parts on by then.

As for cams, I never said I would NOT do them when available. Being that there are none as of yet, just wanted to see what would be possible without them. When they do become available, I would def consider a set as long as they seem to be providing a good gain for the money.

Warrtalon already knows my reasoning for wanting to shoot for pump gas numbers, but for the rest of you here goes... I cannot purchase race gas anywhere near me. The closest place is at the dragstrip which is almost 2hours away. Hence I will more than likely never run race gas but maybe once or twice a year. I am more concerned with setting the car up for 93 as that is what it will have in it every day. I am not a big fan of alcy/meth injection, so that is what I consider a 'last resort option'. No offense to any user of it, just not my thing. I would rather try to get the most out of pump gas as possible.

So would everyone say that 350whp is within the realm of possibility givin my terms?

Girlie

 

Certainly.

 

I would say 350 is a good number to shoot for. Without upgrading the snail, I think that 400 would be hard to attain. To me, the turbo seems small still. i don't have or haven't seen any compressor maps so bolt ons, adding fuel, and upping the boost may be counter productive if the turbo goes out of it's efficiency range. Good luck though. I will definitely be getting more goodies soon.

You see the problem so far in gauging just how truly close some of these IXs are to making 400WHP is that most of the serious tuners of these cars are all doing their tuning on Mustangs or DD dyno, which read low compared to Dyno Jets. I am really seeing some impressive numbers coming from the IXs, but these numbers are mostly all coming from lower reading dynos which can be difficult to gauge just how much power these cars would make on a Dyno Jet.

For instance one of the most recent IXs to be tuned made 308WHP/316WTQ on a Mustang Dyno with just a Flash and pump gas, yup you read right, just a Flash (everything else stock). Now that is hard to imagine, that such a gain can be made with just a Flash, but I mean I have no reason to doubt such an accomplishment. Other EVOs have dynoed on that same dyno and no one has ever questioned the numbers. Now what does 308WHP/316WTQ mean, well when compared to a 05 EVO VIII that made 301WHP/295WTQ on that same dyno and then ran a 12.0@113MPH (and a highest trap of 114.8MPH) you see that this Mustang Dyno does read low. In my opinion to run a 114.8MPH trap, an EVO would need to make atleast 350WHP on most Dyno Jets, to achieve such a high trap. So in theory, you could say that the EVO IX that made 308WHP/316WTQ is making around 360WHP or more on most Dyno Jets with just a Flash. Now slap on a TBE with a test pipe and the car should see another 20-30WHP in my opinion. This should put this EVO at 328-338WHP on that Mustang and 380-390WHP on most Dyno Jet. Now, in theory if the IX is truly making this much power, then it's just a MBC@23PSI, Intake, FMIC, and another tune away from 400WHP and I wouldn't be surprised if this car made well over 400WHP with out Cams, Alky, or race gas. But this all theory and not a fact and unless the owner of this car continues to mod it and take it to a Dyno Jet we will never know.

The best tuners of the IX so far are tuning on lower reading dynos, these tuners seem to be extracting the most power out these IXs with flashes. Even Vishnu, who on average is seeing between 280-300WHP (91oct) on the IXs he has tuned, is not known just how much power these IXs would make on say Turbo Trix's Dyno Jet with 93oct. I think one of the best examples of the differences between these low reading Dynos and Dyno Jets was a thread started by David Buschur. A stock IX was tested on Buschur's Mustang and it made 218WHP, the same IX on the same day (approx. 10-20 miles apart) made 281WHP at Switzer's Dyno Jet. That is a difference of 63WHP or approx. 23%.

Now another IX with just an Intake, Cat-Back Exhaust/Down Pipe, and a Flash for power mods made 270WHP on Buschur's Mustang which if using the above difference would be approx 345-350WHP on Switzer's Dyno Jet. Keep in mind this is with just the above mentioned mods. Now is it possible for this EVO to gain another 45-50WHP with more bolt ons and maybe a 2PSI increase in boost, maybe or maybe not, but my point is to show just how close a IX could actually come to the 400WHP mark with these simple bolt ons. Also my point is that not all IXs will respond the same to these mods, some will make less, but more importantly some will make more. While this IX may not be able to achieve 400WHP on a Dyno Jet, another more powerful IX may just make it.

Girlie what I think you would need to do, is take your IX to one of these excellent tuners of IXs, they may tune it on a Mustang Dyno or DD Dyno which means lower numbers, but so far they seem to be the best tuners of the IX and you can only do the best to achieve such a goal. You would also need to leave no stone unturned, you see a lot of these IXs with just Cat-Backs, your going to need a full TBE which means a test pipe, you cannot afford to lose any power. Also tell the tuners your goal, tell them that your looking for 400WHP, and a conservative street tune, just won't do, a more aggressive tune is needed. See where you stand, I believe with the first stage of bolt ons you should see around 310-330WHP on most of these lower reading dynos and then get it tested on a Dyno Jet to see how close you are to 400WHP. From there it could be simple or it could be difficult, but if they tune it right and your IX turns out to be one of the stronger ones, you should eventually see 400WHP on a Dyno Jet (pump gas).
