A guy on M0dularfords.com had his whippled gt dyno tuned in Texas and made 534rwhp on the 3.375 pulley! He had full exhaust though, long tubes and max boost was 10.5psi. He said the air was really good, but damn that's a lot of power. He also had 52# injectors instead of the 38#.
Yes the whipple HO is a 10psi kit.

OK GUYS, My local tuner who is a mustang tuner Dyno center 454 Dyno in Covington La, and a Ford Saleen reconized installer along with being a SCT tuner station. They are telling me 4 to 5 pounds of boost is plenty for 430 - 450 at the rear wheels. He doesn't reccomend 9 or 10 lbs like I see everyone running on these boards. Help me understand why. I see so many of you out there running more with no problems and stock internals. I asked about a HO Whipple and was told a H.O. Whipple is the same as the standard except with a different pulley. Also, I was going with to go with a Saleen but I sad WTF I am going to go Whipple or KB because of future possibilities of upgrading in the far future. SO that being said is a Whipple easy to upgrade to the HO? I was told it is just a pulley to do that? also I was told that under 10 LBS of boost I dont need to intercool. More of a weight thing in the front of the car. If I later upgrade to a bigger pulley then I can go with an intercooler. I am getting ready to do this around January 3rd and really need to answer all of my questions. And I am taking All opinions, Good and bad. let me have them.
Thanks, SEAN///TASSY5

You aren't going to make 430rwhp with only 5#'s of boost. If it were possible then everyone would be doing it. I wouldn't go to that tuner. There are only two whipple kits, except for their auto options. There's the non-intercooled kit with 6psi pulley and the HO intercooled kit with 10psi pulley. The non-intercooled kit doesn't come with GT500 fuel pumps or any of the intercooler components. it will cost you an extra $1,000 to buy the HO kit, but it will cost you $1700 for the intercooler upgrade kit if you go with the non-intercooled whipple and upgrade it later.
The HO whipple with whipples tune will yield anywhere from 440rwhp to 480+rwhp, keep in mind these numbers are from different cars, different dynos, different conditions, etc. It's very possible that with the same dyno and same conditions, every whippled gt will dyno the same +or- 10hp. You can always use a 8psi pulley to lower the power if you are worried about stock parts breaking, but i've yet to hear of a whippled gt blowing an engine using the whipple tune.

not to change the subject.....but does the PCM flash tool that comes with the Whipple HO kit.....does it just re-flash for the blower tune or does it have the ability to change axle ratios/tire combos....if, lets say, you wanted to run a different gear than stock?

I have spoken with the some of the Ford Racing guys as well as the vehicle program engineer for the 08 Cobra, as well as the engineer from Steeda (Who does the Steeda thing part time, he works for Ford on the Mustang as well) and they both said 8 PSI is all that they would recommend without doing some internals. Yes, it is erring on the side of caution but these guys live and breath this car and are a couple of the authorities on these engine's.
I trust them! Personally I don't want to replace any internals because I blew something up. I might do it at some point for the performance upgrade.
Steeda and Whipple are working together to come out with the 2008 model now. They have a couple of proto-types but have not completed their testing yet.
P.S. I live near and work as a consultant for Ford periodically. I live in south-eastern Michigan, less than 5 miles from the plant where the Mustang is built. I wrote a software application for the plant floor a couple years ago and even have a badge that lets me into the plant. I also have friends and fellow church members who are engineers at Ford for various programs(although not nearly as many of which are still with Ford!). Plus my kid goes to school with one of the Mustang Program Managers. She worked on the GT500 and is now in the design/engineering phase for the 2009 or 2010 Mustang.

The tuner only loads the tune, but you can get the turn done for whatever gear ratio you are using, same with tires. That's the one thing I don't like about the whipple kit, but I guess it would have cost them to much to use sct tuners or others.

Wow! That's all very impressive, but unless you have actual evidence of a blown engine on a whippled gt using the stock whipple tune, then it means very little.

ok then...why dont you get some of the Ford engineers you know and line them up and give them all a swift kick in the arse ....for lets see.....the 2 piece drive shaft thing, the rear end vibration thing, putting crappy rods and pistons in these motors (for a couple of hundred bucks more, stronger pieces could have been installed), the front strut thing, etc......anyone else care to join in to give him a couple of more reasons for applications of a good arse kicking?

by contacting whipple? Im assuming....

You fill out an online form when ordering the tuner through the frpp website. If you change gears later then i'm not sure if you can a new tune from whipple or not.
+1 on the swift kick in the ass of the engineers!

I have had those same discussions with a bunch of them. Some of those decisions are made by the bean counters or worse yet "committee". Engineering costs, manufacturing etc. I can tell you that these same engineers would do it differently if they did not have to bend to the accountants.
I will see if any of them will jump on MF (anonymously of course) and give some answers for those things. Don't know that they will but I can ask.
Engineers can be funny creatures some times. You can engineer and engineer and engineer some more but at some point the design has to be frozen and the car has to be built. Plus all the other politics and bean counter/purchasing considerations cause some of the issues. Not the engineers.
Plus, no matter how good the design or final outcome is, there are always people who will complain and point out how it can be done better. Some of which is subjective opinion.
Not saying the points you make are not valid, but the reality is that sometimes good enough is what you get besides the best solution. I live and breath that every day with I.T. development stuff. It amazes me how people will go for a short-cut now knowing full well that in the long run it will cost more to fix later!
I hate band-aid solutions!

I do not have any confirm-able evidence about blown engines. But I don't want to be the first to prove it either! LOL
As for the points made:
2 Piece drive shaft Crappy Rods and Pistons (Could be due to the beating someone puts on their Stang or the 10PSI plus SC's ). Front Strut Water leak Noisy/Clunky Tranny (Again - Could be due to the beating someone puts on their Stang or the 10PSI plus SC's ).
I am on my 3rd Mustang (2000 Gt Coupe, 2005 Premium Gt Convertible and now my 2008 Premium GT - Steeda). I have not had any of those issues fortunately. Lucky I guess!
But then nothing is perfect!

As an engineer I will say +1, we constantly are forced to design things less than optimally due to customer or management stupidity. Always ends up costing in the end but whatever, as long as the paycheck clears.
And I agree a forged rotating assembly would be great but for 90% of car buyer the powders rods and pathetic, oh uh hyperteutic (sp?) pistons are just fine. Honestly I am surprised they will take 450 rwhp with is like 75% more than what it was designed to do. Check out chevy products and most of their engines wont take over 4-6psi without poping with is less than a 50% addition of power.
And even if the rods were better something else would break at 475rwhp and we would complain about that.
For what the mustang is, I think its great.
Personally like I said I feel confident that 8psi on a whipple HO will run forever, and for that matter 10psi probably as well. But if life has been a lesson for me it is that if 1 in a 1000 will break, it will be mine. So a mere 425rwhp should do nicely.
Thanks,

They also have a higher compression ratio right? Not to mention it's a pushrod motor which is complete different. Higher compression plus more boost is bad.

RE: Whipple H.O. kit - 
those numbers are big!
, but unless you have actual evidence of a blown engine on a whippled gt using the stock whipple tune, then it means very little.
