Vargas Stage 2 Owners

I'll buy your Vargas turbo for 1200 if you don't want it anymore!

I dont doubt your turbo will make power but taking my dyno that was done on a much lower reading dyno, in the middle of a TX summer and comparing it doesnt scream accuracy. Additionaly my dyno also did not source tach signal from the OBD2 port, it was sourced from the crank pulley. So the smoothness up top on my curve is legit.

I know its expensive to get a compressor map. When you said you worked with garret I wondered if they might have built this turbo. I look forward to see what your customer base does with these turbos. Too many companies out there fudge results that Im a little bitter TBH.

After going through two turbo setups I picked the GTX2867 by researching and comparing real world results on various platforms. I am the one that put together the first MAP/GTX2867r kit and now Adam sells a version of it.

I have no nut swinging loyalty to it as I put together a kit to reach my goals with the help of Adams tuning. I am skeptical of your spool data and % of power difference. I look forward to seeing customers results and I hope everything works out great for them and they are happy.

Why dont you hop in your car, go to a parking lot and put your left foot on the brake petal as hard as you can, then put your right foot, that would be the gas petal , and mat that. Then come back and give us the boost pressure and RPM you see. This would give you and I a comparison of the Vargas Stage 2 and your Turbo. Im seeing about 8 psi at about 2900 rpm. Would be a fun little real world test, and would answer your own question. It wont tell us everything, but any Data is good Data.

Flame suit is on! Two cars, both bolt on cars, one has stock turbo and the other has VS2. The stock turbo car will bus length gap the VS2 from any dig race (stop light, 1/8 mile 1/4 mile). No matter what trans your car has the stock turbo is faster from point A to point B. Provin by previous threads in this post.
Now if you add parts (convertor) sure, but keep in mind a good convertor and labor to install doubles the turbo price.
Now if you're a roll racer, or a track/corner carver the VS2 will shine.

I do not think bus length, the stock turbo may get out of the hole quicker, but I will run him down well before the 1/4 mile, prob before 1/8 mile. I challenge anyone in the bay area to come test this against our shop car, you bring stock bolted EBM, we will run against our Stage 2 Bolted. In for results....

Do you have airflow data in terms of lbs/min for your test vehicle?
Thanks

We do not have any external data. Just whatever the factory DME is showing through the Cobb, it was posted in a log somewhere. Only problem is these cars have no MAF, its just a calculated value so I never trust it 100%.

Just checked one of the later E85 logs from testing. Ex Mass flow in lb/min is showing 57 lb/min at 7K RPM

This is exhaust mast flow, not air mass flow. Both are actually inferred and only inferred for calculation purposes. The only thing they should be used for is looking for exhaust turbulence, and airmass should be used to see if there is still velocity behind the boost. Big boost with tapering airmass = no power/useless. Airmass should not be used as an actual measuring point of airflow via lb/min rating.

Well yes Adam it clearly states Ex Mass Air flow in the parameter title. So yes that is an exhaust number. I did not log the actual air flow parameter so its all we have to go on. As I also stated I never trust any of these calculations as they are simply that a calculation based of different factors the DME is seeing. If we wanted to read true Mass Air we would need to put a Mass Air flow sensor after the filter, and log it using an external logger. Done it many times on other platforms, not going to bother on this one.

No one I have seen has any proper documentation on these motors, not even the people pushing them to the limits. To be done right it needs 10-12 external sensors, including Exhaust back pressure, EGT for each cylinder, boost at the compressor outlet, intercooler inlet, intercooler outlet, air temps at compressor outlet, intercooler inlet, and intercooler outlet, and a few more. This is the data people should be collecting when pushing to the limits to see exactly what is going on not relying on factory sensors. So far no one I have seen has done it. If we were pushing we would.

Another point to add to this post is that people posting about their experiences right after throwing the turbo on aren't going to be indicative of what its like properly tuned. The tune will affect spool a good amount.

This is one of the THE most important things to consider. When I did the swap from Stage 1 to Stage 2 on the test car, and took it out. I was honestly disappointed, it felt slower. After tuning it, its a whole other animal, spool 100% livable, and it would embarrass the stage1 car from a dig or roll, by the 1/8 mile mark.

he has a stick car no power braking for him.

Disagree. There really is no proof of what a properly tuned vs2 will do from a dig yet. Somebody in here went a low 12 at 120mph. I'm willing to bet that car was not yet finished tuning wise. Not to mention if someone throughs the transbrake tune on this turbo and you have a tbraked stock turbo car, it won't even be close on a clean run.

Wow Some people sure got their panties wound up over a well priced turbo upgrade..

I think Vargas did well with the ambush and producing a solid option for those that want factory appearance and top end pull. Look forward to seeing more results as these units get out there.:cheers:

Ron? Lol

Yea I thought Alex was Ron? We all learned eachothers Reah names today from the Facebook group, maybe I got it wrong
