765 whp! VTT GC Dyno Update

[Flinchy]

We should be testing those soon, just don't want to make too many changes to the car before an event. We're told the Nizpro transmission is about 2 weeks out, we're thinking closed deck, BB GC+, ported head and Nizpro transmission could be a nice combo for the next Shifts3ctor.

We may just throw the +'s on the manual transmission car after AZ NFZ and see what we can make. Tony has it down to a science, and can swap turbos on the car in around 2 hours. The modular design of the GC's makes it much easier.

RHD rear housings still on the cards at all?

Hi Flinchy,

Yes, they're still on the table. RHD GC's will be available but require some modifications to work; right now Nizpro is doing some testing for us. Ultimately we will be performing those modifications in-house and they'll be available ready to go. For now, testing is slow and steady... hope to have more on this to post in the next few weeks.

ah so going to be modified lhd housings (or heavily modified charge pipe to clear the rack?) not a true original fitment level bolt on.. kinda disappointing but if you aren't willing to to a separate casting because large cost that's fair I guess . Get what we're given lol

I've heard nizpro has had one hell of a time getting it to work.

Not sure who you have been talking to -Nizpro told us directly that they had absolutely no problems getting them to work. They simply modified the compressor outlets to get them exactly where they wanted them, modify the charge pipe to match, and that was it, no other changes needed. We're pretty excited about them.

so why are the AEM screen shots labeled "GC+" when youre supposedly advertising GC? even if its a typo its not very reassuring since no one else out there but you has posted glory runs like this

Hey guys,

We got the white car (6MT) back up and running strong and thought we'd revisit some GC numbers for your viewing pleasure.

Car specs:
Built Short block
Stock head with bad valve guide seals
GC turbos
BMS DP's
Custom Exhaust dual 3" into 4"
Shotgun Single Barrel
VTT Rear Silicone intake
Custom VTT front intake
VTT DCI
Custom VTT Catch can set up
EOS Intake manifold with built in PI
Custom LPFP set up
100% E85 for fuel
MHD tune by V8bait
FLASH ONLY
ADE Intercooler
AEM AQ1 data logging set up with Dual EGT, Dual BP, Manifold Pressure, FMIC In / out temps
6MT (4th gear logs)

Numbers:
Now, on to the numbers. Note that we're referencing boost from the AEM logs (screen shots attached) in lieu of MHD reading it in the charge pipe, which isn't accurate. The AEM map sensor is calibrated and tested to be accurate. Datazap of course references the MHD values for those who care.

765 was made on 29.3 psi at redline
740 was made on 28.5 psi at redline
693 was made on 25.4 psi at redline
655 was made on 22.8 psi at redline

These numbers speak for themselves, but any comments from competitors or their pawns about these reaching a bottle neck around 650 whp should be recognized as the marketing gibberish that it is. These turbos are very efficient. 600 wtq at 3500 rpm and no wheel spin on the dyno!

Hi! Good catch, although we did already address that earlier in the thread:

So this is gc+ or gc?

I thought at first it was just gc but your flash file says gc+.

100% totally just regular GC's. GC+'s are a different ballgame, and when we're done with THAT testing we'll be making a whole new thread with all the details. We've been exceptionally busy at VPG.

Chris

Thought so. Had someone argue that it was gc+, i was sure they were normal gcs just with more timing.

Thanks for answering

Healthy engine is the big difference, but yes, you're correct. GC+ dynos look a lot different.

Tony was running tunes from another testing session. All these gc's share a modular design that simplifies tuning, it's really nice, however the wgdc base was a little off at spool. You can tell by the boost peak there before the PID catches it, and by how low the trims dive expecting a little more airflow. Very astute observation.

And yes, these runs are glorious.

HAHA! No no Chris, let them think these are GC+ results based of an old AEM project name I never changed. I mean $#@! up until 2 weeks ago, every AEM log no matter what turbos I was running said "Stage 3 project" as you have to do a bunch of $#@!ery to bring all your filters into a new project. Its perfect, let them think these are GC+ numbers so when we do drop actual GC+ numbers it will just be like, OH....... I guess those were GC's after all. Also keep in mind this is the dude who promotes Pure for a living, so him questioning the results that make his buddies offering look weak is not a shock. In case you were not sure. Pure is the company who hangs its hat on a 711WHP dyno spike, but all their other results are people making 675WHP on 900 psi...

We're ready for a head to head dyno any time you are. Open invitation. You can title your dyno logs anything you want, we'll just call them "second place".

I have no dog in this fight but it makes all the sense in the world that GCs would outpower any OE-based turbo upgrade due to their larger, freer flowing turbine housing & manifold combo. No huge surprise there..

[Chris@VargasTurboTech]

Nailed it.

[ChuckD05]

Lol it's cool, I'm not really defensive, but I'm just not following you. Sure it was a little krispy. And before he broke 700whp it was fine. All i know is i got a text around that run that it developed a misfire under load, he said it was one if the coils. He replaced it and continued. Sometimes these things happen, but please tell me how you can verify a coil will work at 700whp by testing it at 500whp? I just don't understand, I'm not being defensive. You can't judge a coil by how it looks... is that wrong to say?

Edit- maybe you confused when I said known burnt as meaning known bad. By known burnt, i mean it had some heat deformation from his engine fire. He replaced a few parts after the fire but not everything, as that would generally be considered a waste. It was functioning, however. I also don't think this qualifies as a "big dyno day" or whatever, hell I was sitting for my boards (9 hour test) and he just rolled the car on to see what it would do post fire. That's all I have to say on that matter, I thought the numbers were pretty nice consisting all of the above

Ahh, i have been away for a while, sold the car... I always saw that you were super intelligent and knew wtf you were doing and way back when all the tooners were showing face I asked you for help and you came through big time... Thx again...

Fast fwd a year now and your tuning VTT's car Thats great to see!!!

[berns]

ok, ok, in car, street vids. do it!

I still dabble in tuning, just not commercially really since I've been so busy (but I'd make time for some spare cash haha). I like the new projects since they're less bread and butter, what can i say i enjoy challenges. What did you replace your bmw with?
