ideal would be to have the max possible PSI all over from 2Krpm to redline

So i guess its fair to say that its putting down 425-440 whp with a much better power curve and around 450 whp torque, on a mustang dyno thats pretty impressive. I can't wait to see the pricing on this!!

dzenno if you back-read some (i know there is a lot of garbage in this thread to sort through) I wasn't running stage 3+ with the upgraded turbos. The dyno is comparing stage 3+ on the stock turbos vs. upgraded turbos and more boost with a different map. Shiv was on the phone with us all day sending new maps to try based on info we were giving him.

threads like these are pointless..come out with the pricing, availability, power data ONLY when all that data is available.

i don't understand why you would tease everyone, make it go on for 26 pages, then chastise them for speculation.

non-xi 335's make 20+whp more on a mustang dyno, for instance a completely stock 335i made 250whp/280wtq on this dyno. While in "valet" mode (stock boost/timing) but with all my mods I made 250awhp/280awtq. You can really see the difference on these types of dynos. The 205/65 snow tires on my car probably didn't help in any way, but you get the idea. (i'll be back on this dyno with my summer wheels/tires in a few weeks just to see the difference).

So that being said, I won't be up around 425awhp on a mustang dyno with pump gas but there will be a significant delta to be had.

I WILL be going to a dynojet in a few weeks that I have a baseline at and many other pulls so we'll have some good comparisons from there.. comparisons people on here will be more used to seeing.

oh I'm sorry, I didn't realize you neglected to read the title of the thread which clearly stated this was a "build" thread. I also didn't realize someone forced you at gun point to read the whole thing hoping for something different.

I told everyone my build time-frame throughout, posted updates as they happened, and posted up data as I got it. I think there are a few people who appreciated it. This forum has been very boring lately, I would have enjoyed a thread like this a month or so ago... instead of just sitting around complaining that nothing is getting done in the upgraded turbo world, I went and GOT stuff done.

You'll get over it, this process has happened very quickly and we all appreciate the efforts put in.

It is amazing to me that people get upset or mad at you for upgrading your turbos and posting the progress.

JP isn't a vendor. He doesn't owe the forum anything. He can go about his life and upgrade whatever he wants to his car, and doesn't have to give updates to no-names all across the world.

Are you going to ICS? Might be worth the trip down from MA to check it out. Maybe a dyno day?

JP, Ignore the trolls. It looks really bad when people are mad at you because they want something really bad. Once, I posted about possibly upgrading my turbos and got flamed to the ground. Although my topic held less water than yours since I currently am not in the process, don't let them get you down... Now, on the other hand, I'll be the first one to try and bring the price down by downplaying its capability and therefore degrading the value so the price is easier for me to aquire, but it looks like you're doing a damn good job of holding the value in your product so, i'll concede

Looks good, I think this will be a great, fantastic upgrade for many people who are on a more realistic budget and will add another common upgrade path element not only for us, but our other competition on the road will know about.

When I see a supra, that big single possibility is always something I'm considering before I start acting too cocky and soon we'll be there too. Thanks for being the Guinea pig!

Call EPL, they want to do a single 35r badly... eventually they'll get a 135 and do it for themselves, but if they get a customer right now they'll start right now
