Aftermarket Turbo Options

[El_bigote_AJ]

Thanks !
Thought it would make a little more than that, but still very respectable gains.

It’s an is38 “+” not a hybrid. What Frankenturbo touts though it that you can “safely” push it harder than oem...

TPC has had several failures. I don't think anyone can resolutely say "This is the best." They are all gambles. Pick one, run it, enjoy it.

There have been? I'm not doubting your word, but i've not heard of any. I'd argue i have the most miles on mine than anyone else, nearing 25k miles. I had the intake off for a new PCV system and zero shaft play so far. Still running great.

Meh that's how these things always go. I thought more power on my corvette would make it 2x the fun.... I'm not that excited about a 800hp corvette anymore and it just kills the balance of the car and just wondering what will break next. Every car has that sweet spot of power vs cost vs reliability vs fun

absolutely been here, built a 1k hp car previously and then realized it was like having a super hot crazy stripper for a girlfriend, sounds good when you're drunk and crazy fun sometimes but absolutely not worth the headache.

after looking into all the options if it were me I'd just get a "L380" from littco

feels to me like ~400whp is the sweet spot for these cars and then run them on as strong an ethanol blend as can get

yes. im just saying no one is immune to failures.

yup

400ish whp is also the sweet spot for the limits of FWD traction with these cars IMO. Barring extensive suspension modifications and radials.

What's the "+" part?

 

[El_bigote_AJ]

What's the "+" part?

That’s Just what they call their product, cause it’s not a hybrid In respects to the factory housing with a larger compressor/turbine, it’s just a china replica housing with with and heavy duty shaft bearing and a compressor blade with an extra blade.

On the R the breakover point $$ to power is sticking with the IS38 and doing an E30 tune. You get 400-420hp, factory turbo, factory fueling, can easily revert to a pump gas tune and things stay reliable. To get more power from there is a whole bunch of money and potential headaches.

I am sure the dyno reads a bit high but my fwd GTI puts down 450whp on michelin p4s tires on the street in third gear WOT with ease.

Heck yea, would love to see that.

I'm on stock suspension too, with open differential.

I like the turbo a lot. On mine I hit 28psi at 3750 RPM. Peaked at 29psi at 4000 RPM and then held 27-28psi to redline. But my IS38 hit 28psi at 3100 RPM so the TPC20 spools about 700 RPM later.

Jim, it is normal.
If you want faster spool, take LM440 IS20.

Yesterday I installed the IS38 LM575 making immediately 5.9 - 6.1 = 100-200 kmh (60-130 MPH).
Spool is almost as fast and early as LM500 TRACK and it wants to generate more than 600 HP.
Here the video of the LM575 IS38 in Leon Cupra (Golf MK7 R | CJX engine)

I understand it's normal. I was just responding to someone else who asked for that info.
