Bigger Turbos

[Brian Keenan]

We know the twin turbos used in the V6 Stinger are very small. They're probably only going to be good for about 500 horses. Let's discuss what are the best options for bigger turbos.

 

[KLR STINGER]

Turbo options are virtually unlimited. Really depends on your power goals you want to make and the power delivery characteristics that you want.

I'm pretty sure the stock turbos are gt1752s variants with custom compressor and turbine housings to Hyundai spec. Doesn't leave alot of room for traditional hybrid modification with bigger hot and cold side wheels, But alittle bigger should be possible. Someone like Vargas turbo or Pure should be able to work some magic.

If you venture outside of the stock frame turbo, the sky is the limit. Packaging isn't a problem with custom setup. Lots of engine bay room and the internal manifold to the head means one outlet pipe to feed the turbo. There would be good money in a replacement bridge pipe from the head to a standard v band or t3/4 flange.

Something that moves 40-45 lb/ min of air a side, with a BB center section, should give you good spool with 800+ HP potential. Lots of ways to get there

Wouldn't removing the exhaust restrictions effectively increase boost levels?

Those attempting to do so, so far, find the ECM detects and "overboost" condition and shuts things down.

 

[KLR STINGER]

Increasing boost isn't the point of bigger turbos. More airflow capacity is the goal. Stock turbos can only move so much air, limiting HP. Once tuning fully available, the limits of the stock turbos will be readily apparent. At that point big things will happen for this platform

The stock compressor wheels appear to be smaller than the exhaust wheels, so there is a great deal of room for improvement on the compressor side. The biggest problem is going to be tuning. We need to crack the ECU for this, because a piggy back will not adjust properly for higher boost from higher flowing turbos. ECU tune, will have to come first.

With that said, we have looked at the available space, and it looks like a G series turbo from Garrett will fit in the stock location (with some custom manifolds). So, a pair of 650 HP turbos would make for a wild ride when tuning becomes available.

G25-550s would be awesome. Small package.. Huge flow. Super efficient aero and spool fast. Most advanced turbo available if you ask me. That's what I'd do too!

Until tuning the ECM is cracked, the larger turbos are useless. Piggybacks won't help.

 

[Never thought]

Can the engine hold up with that much hp?

 

[KLR STINGER]

No chance it lives with g series 550/650s. But only one way to find out where it breaks...,,

Its been cracked... we should have a new tool in the shop for tuning April 20th.

I am going to make an assumption, that it will be good up to around 600 WHP, after that... it will be questionable.

I have plans on taking the stock turbos as far as possible. Then modded factory turbos, as far as possible. Then, its build time. No idea how far we are going to be able to get without costs becoming an issue... but if we don't do it, then nobody will

 

[KLR STINGER]

Atta boy!

Are you talking about another piggyback solution, bench tuning the ECU, or a handheld programmer?

Well, damn.. ONLY close to double what it comes with, and more than enough to embarrass just about anything else on the road. Guess I should consider a different purchase...

With turbos you tend to have to balance out top end power vs lag.

Our turbos are small but that is basically how this car drives with almost no lag. Feels like a N/A car.

You want lag? Try driving an AMG CLA 45. 375 HP out of a 2.0L 4 cylinder. Step on the gas and nothing happens for a LONG time, then like someone shot you out of a cannon. VERY annoying!!!!
