My TPC20 Turbo Build... NOW TPC38BB Build

[BecauseMotor]

OEM DV, Oil Change Kit, and Vibrant Resonator came in yesterday.
UR down pipe ordered.
Vektor Vent Gauge is in process of being ordered. Just waiting on invoice from US supplier.

I was going to go with P3 anyways... but then when MAP had a delay with their down pipe, I ordered the UltimateRacing one which was a lot cheaper. So I figured I could use that cash on top of the P3 and still come out the same!

It'll be interesting to see how this TINY car reacts to just 3 vents up front. I'm sure it'll be just fine.

yeah the two main drivers one are needed for me, I would say p3 gives you half of it which is nice. but either way the eletronic gauges are a lot of money and im a broke fool haha

stirring the pot... lol

Everything is installed.
I have dyno numbers. Not that great.
Butt dyno says all is great.

What were your dyno numbers?

 

[Diggs24]

Did you log the dyno run? Can be quite eye opening.

 

[ZuMBLe]

In for dyno and log.

OK. Final mods were as follows:

- TPC20 Stage 3
- Precision Raceworks 3.5 v2 LPFP
- Ultimate Racing Catted and Resonated Downpipe
- Vibrant Resonator replacing OEM resonator
- OEM catback
- RS7 Ignition Coils
- 1 step colder plugs

I was not able to be there for the tuning due to COVID restrictions.
I did NOT get a before tune.
I did NOT get a log of the dyno run.


I was tuned with United Motorsports at Caste System Performance in New Jersey.
Dyno used was a DynoJet.
Ambient temps were about 90-95º

On 93 pump gas, I put down 361.62whp/337.26wtq.

On "e22" as claimed by Tuner, I put down 377.98whp/353.56wtq.

That same dyno has an is38 tuned GTI putting down 358whp/375wtq. You can see the comparison to that is38 in the 1st dyno image. It's the one with the awesome torque curve. They were also tuned by UM.

Tuner is saying the turbo is "a pig."

Compared to my Stage 1+ Unitronic tune without a downpipe, this is a pretty massive improvement, but the dyno numbers and torque curve have me pretty perplexed.

Is the IS38 comparison from same day? Ambient in the 90-95f range is a killer for stock location ICs. They get heatsoaked really fast.
