Vargas GC turbo initial review

[Sport-injected]

I bought the @VargasTurboTech GC turbo in march, did not receive until June and finally this weekend installed it.

I decided to go to the GC turbo from the RV6 r365 for a few reasons.

1. The 93 dyno numbers that @Neddih shared when he tuned with IMW were very impressive. The first drop-in turn I've seen that high.
2. The torque curve on his dyno was also very attractive, came in much sooner and a higher number than the R365
3. I love the RV6 turbo but since I don't plan to go ethanol I wanted to get some of my low end power back. When at Watkins Glen, there were a few areas coming out of turns that the turbo lag killed my straightaway speed potential.
4. The compressor wheel is of a very good design, the turbine wheel is 9-blade. Vargas has been making drop-in turbos for Audi/bmw for years, I believe they have a good design in place and they took what they know and applied to the Honda platform.

First test drive down on the IMW starter file, already I can feel how much sooner the boost comes in only at partial throttle. Cannot wait until final tune to see how it feels..

I will continue to update this thread as time goes on.

The only change I made to this turbo was opening up the compressor outlet port to match the oversized PRL TIP crossover pipe. You can see details if that on my build thread if you wish.

First pics are the RV6 vs GC

After getting some driving in today, this turbo is a big change in boost response and torque, I am now breaking tires loose by 4000rpms when previously I would not be at full spool by then. Very happy!! Haven't taken it above 4500 yet, will tomorrow when I get my first round of datalogs for IMW. The car sounds totally different now, it has a mean exhaust grunt when spooling at around 3000rpms. Loving it.

How did it feel!? haha

Can't wait to hear how the tune progresses, I know the turbo feels great lower RPM but it really opens up in the higher rpm.. If only I could spend more time at 4500+RPM lol

Hard to tell on the first revision, it def rips down low, it hard to find a good spot to do the 2000rpm to redline pull in 3rd gear so I'm half paying attention to how it feels and half looking for cops or cars pulling out in front of me lol. Once I get the second revision I'll do some sport pulls and gear rowing to feel it out. You will be the first to hear about it!

I tried to get the turbo sounds this morning on way to work but it was raining and lots of traffic. Can't hear it, but I'll post anyways.

@Neddih it feels so good to have bottom end back, as soon as press on the pedal at lower rpms it start to put me back in my seat, almost zero lag, so refreshing. My gas mileage is going to take a dive for sure hah.

Dam bro what a difference on the outlet between the 2 GC turbo for sure looks bigger

Courageous!

Courageous!

Thanks, Had to match the port size to the PRL crossover inlet pipe for optimal flow

A quick video this morning of the @VargasTurboTech GC turbo noise through the @PRL Motorsports cobra intake. the video doesn't capture the full depth of the sound but you can certainly hear the air being pulled in.

try to keep temps on the low side.
