Correct 👍

So you have charge pips, down pipes, mid pipe and intakes with the stage 2 turbos?

No mid pipe, and stock intake with drop in filters. See my signature.

My plugs were also pretty worn, so should able to do little better with some fresh plugs.

I have a question. How does pt 2+ compare to gc+ turbo upgrade? I was told at a shop that the pure turbo 2+ has more lag than the gc+ turbos?

[Ed_rx7]

Yes, pure’s are laggier from my understanding... probably due to the fact that they are just bigger wheels in the same housings. Whereas the GC’s redone the housings completely to address restrictions associated with more flow

[Upgradetp]

Ok because I didnt know if the guy was just trying to sell me what he had or was telling the truth. So the wheel is bigger but that means higher hp at the sacrifice of acceleration but if the gc+ is similar in gains then why spend more money on pure? Im trying to figure out the differences between the 2 because I figure there must be a difference.

[Ed_rx7]

There is a difference... pures use stock housings whereas GC’s have their own cast housings

When you ask why spend more... I think you have already answered your own question!

I just ran 2 configs without shipping:
Vargas GC with install kit = $3774
Pure Stg2 w/ inlet & install kit = $3995
The + models of both have larger wheels, which do take a little longer to spin up (and at a later RPM), but give higher output at higher RPM.

Pure has a core charge (removed from my cost estimate by picking "customer will send in turbos"), and they do (re)use and re-mill the OEM housings. The OEM housings are a little more restricted than Vargas new (lil bigger) housings, so a PS2+ takes a little longer to spin up than the GC+. Some argue that Pure has higher quality control.

Since Vargas engineers their own housings they can flow a little more so the turbos spin up a little quicker (starting at lower RPM). I guess the cost of engineering and manufacturing of the housing may be offset by slightly less QC (or maybe Pure can spend more time with extra-fine milling). I've heard that Vargas makes good on QC complaints, but their bigger housings gets them a full notch ahead in my book.

The real answers come from where in the RPM you need the added power...based on 6MT or DCT...roll race or drag...driving style/type...etc. Compare against dyno charts people provide and use those to place your power where you want it.

Ok thank you for explaining that. I figured that there isnt much of a hp and torque difference but one spools up faster while the other has higher top end. I appreciate it

Stock fuel system on EcuTek on flex fuel. Made 580 on a mustang dyno but need a lot more fueling.

[arn671]

Any promos coming up at all or is it just Black Friday that these come down in price?

Upgrade the fueling and add port injection

[Upgradetp]

I'm supposed to pick up my car after it gets dyno'd with a custom tune from Cary. I'm hoping for mid 700's whp.

What's your setup?

Dinan intake
AA EL midpipe
VRSF catless downpipe
CSF Front mount heat exchanger
CSF Top mount intercooler
VRSF Chargepipe
4 pin crankhub
(I may be missing something)
What's been added is stage 2+ turbos, port injection, hpfp,with custom cary e85 tune.

I noticed your setup is similar to mine. If you dont mind telling me, what's your whp and tq?

Just a single map for now, tad over 600 whp/wtq at 25psi on 93. Going to crank the 93 map a bit and also go full E85 this season.

It says F-SERIES S55 high performance fuel pump 601-0148 on the invoice but as of rn i cant remember which company they went with. spool or another. and for PI BMP S55 750 CC

Yep I'm doing a direct port meth setup

BMP with secondary pump. I found out that the venturi gets clogged its a common thing so be mindful of that depending on the gas stations you go to regularly of course.

[///BMW Junkie]

PJT E85 tune
PS2+ (redesigned 2020 version)
Dorch HPFP kit
F10 M5/EU5 injectors
NGK 97506 at .019"
VRSF DP's
AA single midpipe
AA 3can muffler
Stock LPFP, stock cooling and stock intake with drop-ins

NO METH or PI!
