    Rb's are TD04L correct?

    I'm not an expert or anything, but the Vargas look something like TD04HL spec? Rather than speculating we should just let him answer though.

    Sorry if I'm being dense...

    Neil
    Honestly, no idea where the $1999 number is coming from. On the site the stage 2's are $2499, thrust upgrade is $300 and core is $400 which you get back one we get them. Site will be getting a major overhaul soon.

So not sure why it is being referred to as one. It appears to be a smaller wheel that allowed use of the original TD03 centersection and eliminated the need to re-flange the turbine housing to clear a big inducer.
    This is not correct. This is business, I do not need to reveal every spec of our wheel combo. Unfortunately Rob you do not know everything there is to know about turbine wheels, MHI or otherwise. This is a TD04 wheel, shaft, head, etc. We just had them made to our own specs, which means you are correct at least that it isn't one of the TD04 variants you mentioned, because when you have something made custom, its that custom. That's like saying a Precision turbo is not one any one of the Garrett variants. Well that's correct. Its a precision turbo based off garrett turbos, made to their own specs. But thanks for jumping in my thread and trying to tell everyone what we used.

    I'm not joking one bit when i say that the quality of these turbos is TOP NOTCH.
    The turbine wheels certainly do seem to be significantly smaller than the RBs:

    The Vargas turbine wheel has 11 fins, while the RB turbine wheel has 12 fins.

    You guys can keep up your comparisons all you want. We did not use the same wheel as Rob did and we have our reasons for doing so. He took off the shelf MHI parts you can get anywhere for next to nothing, and used those(there is nothing wrong with that, we decided to have our parts made. If they end up not performing as well, we address it then, but we are confident they will. This is why you basically give 5-6 sets of turbos away at what you paid for them to do some testing.

    I agree, as long as our stage 2 can hit 500 HP, we are happy. Trying to run any stock frame turbo, ours, RB's, etc. above that level will result in premature failure no matter how you slice it. Thats just a fact.

    will the stage 2's on meth reliably make 475 whp? 430-440 whp on pump? key word: reliably? if so, then these sound really good...

    the pictures are from two different angles/perspectives which can change the perception drastically...

    Do RBs hit 425 on pump? That certainly would be nice but didnt know if thats even been done yet

    Well that's disconcerting since I'm running 417rwhp on my stock turbos with meth. I'm not saying that as a slight, only that now you have me wondering when my stock turbos will grenade on me. Click here to enlarge

    Thats exactly what we are shooting for. They should make the number no problem. No one knows precisely a stage 2 style upgrade starts to work too hard but we do know it right around the 500 mark. They will make it and more, but pushing them that hard is very hard on them.

    I can confirm that with my upgraded turbos (not stating the brand - maybe it's not important) I got 370whp on a Mustang dyno on 93 octane only, while my best result on 93 + meth was ~355whp (GIAC Stage 2 Race). The best result of a FBO JB4 on 93 + meth was also ~355whp on that dyno. And also the powerband on upgraded turbos was much better after 5000RPM.

    Virtual Dyno states that a Mustang result is 18% lower than a Dynojet Result. If you multiply 370 with 18% you get 435.

    So...it's possible Click here to enlarge (unfortunately there are no Dynojet dynos in my country that I know of).

    With RBs I do around 430rw on pump 91, running around 16psi and 8 degrees peak advance. Have never wanted to push it further as I run E50 most of the time these days anyway.

    yea same here with not really running pump, but if I could have 430 in the off months on 91 I would be more than content with that

    I do however hope to push close to 500whp for track/race occasions which is why I will always rock jb4 to have great flexibility in boost control/tuning..

    Few steering wheel buttons beats a complete flash change + several maps being made/paid for different fuel configs


    Tony is there any further detail you can share on these perticular wheels that may help answer some questions before strangers 1,2,3,4,5,6,etc pop up in here firing obnoxous questions at ya ? lol

    Ill try my best to get these installed ASAP and tuned/dynoed asap so there is data and not speculation out there though

    430 on ACN91 with RBs is pushing it (not because of boost but knock prone environment with ACN 91)...with timing correction logging across the board you'll see why..16psi with 8deg of timing will have corrections even with 93 Click here to enlarge numbers can definitely be pulled off but it won't be pretty (i.e. happy tune)

    Those numbers sound about right, with 500+ glory runs. But honestly and everyone knows this but maybe not want to admit it. Pushing them past 450 is just pustting them on borrowed time. There is a reason a well built turbo, has a high failure rate(according to some people), and I do not think its poor build quality. I went all out with my thrust parts to try to help, we shall see if it does.

    They are custome made TD04 shaft with a fullback design on the inducer and 11 blade exducer. I am not going to share anything other than that. We are entitled to keep some of our specs to ourselves as other people are more than likely going to get into this game at some point.

    Got ya, thanks...

    I ran my 135 at around 450whp on stock turbos for almost 40k miles when i bought it used with 48k without issues at all, sold it with OEM clutch and OEM turbos on it, new car was beat far less and they are smoking at 32k miles after being tuned for 10k ... seems hit or miss i guess...

    I have expectations with these and they havent changed, time will tell as I work with Tony and Terry... I have them in my possession and will be installing them in the coming days.

    There is a reason that the smaller of the stage 3's is rated for around 500hp. There is also a difference between glory dyno runs, 1/4 mile runs, and road racing/tracking. Each one is progressively harder on the engine and turbo's and the only turbo's capable of a sustained 500hp on a road track would be the stage III's.

    RB's and the stage II's are for drags at that level. I would say they are 400hp turbo's for tracking.
