where did you read that? as far as I know I drove in the first fully built 20g 2 years ago... and my friend put it in the 10.0s... ( took 1.6 bars on C16).
Now, as far as HOT air.... I think the k16/gt28 set up has a lot more to do with that then a 20g....
Hot air may have to do with improper cooling( intercoolers) and or the rest of the system... like choking exhausts for example... popular 200cel cats are a no go at these level...

furthermore... it was popular to stuff a gt30 compressor wheel with a K24 housing and utilizing the K24 turbine wheel.... run NO water lines on top of that.... and that is even a bigger compressor wheel then the 20g.... how come there is no consensus on that?
tuners will sell products they make most money on... do your homework before you buy.... better yet get a ride before you buy.... maybe that way you will not buy into "hot air"...

 

Markski,
It's likely "concensus" was not the right word and I do not want this thread to become a 20G debate. A bunch of us were standing around a while ago discussing turbos and what we've done in the past on different vehicles and this came up. It is strictly my opinion until I SEE further data and videos. Compressor maps aren't exactly floating around on all these hybrid turbos you know!!! This car isn't my first rodeo and I don't take everything everyone says as gospel. I did a lot of homework before I decided to do the 18G's. I knew about the 20G's when I did these, but not enough technical data for me to warrant a jump. (Plus, I wanted to have another level to go to when I get bored here !!!) Thats why I would love to see a video of a 20G car against an 18G car, you know all things being fairly equal. If the difference is the same as the vids in this thread, might be my next move. So no disrespect intended. I know you jump in these threads to try to stop the dissemination of "bum scoop" when you can and no one is questioning your experience.

Flash,
My redline is around 7100 but I shift at 7000 and it really feels like it is still pulling pretty good. Unlike K16s, I usually run out of highway before I run out of turbo.

 

does a tiptronic change anything? would like to know the best set up for my TIP for street playing use only.. no track no drag strip..

 

Nothing like a day of street racing to get you mod shopping!

 

The Audi "chase car" is an EPL car as well .

Great compare guys!

I still believe that the 16g's are the best k16 hybrids available at the moment.

 

Mark,

Im speaking from my experiences of 1 car...so take it with a gain of salt.

In normal weather conditions on 18g car we see IAT delta of about 40 degrees from the begining of the pull to the end of the pull. So if IAT starts at 70 it ends at 110.

On the 20g car we worked on, IAT delta was closer to 80+.

In my opinion the 20g wheel is not a good fit for the k24 housings.

As TTboost stated this thread isnt a 20g debate. I just think that in most if not all cases, my customers are better off with 18g wheels over the 20's.

 

Less is more.... unless you go really, really big.... and then ultimately suffer with driveability issues.... 16G and 18/24G then GT35R's.... have to believe that at some point you're not making enough power "under the curve" in which case highway pulls and drag racing are the goals and not track performance. Keep it under the curve brother! 586AWTQ is MAMMOTH power on the street no matter what anyone will say.... Plus its probably reliable as hell.... you can probably flog that motor endlessly and not blow it up vs a 700WTQ car...

 

ttboost... great meeting you this weekend! it was nice to put a face with the name bro....

 

Yeah, same here! Great meeting all you guys, could have been warmer though!!!
Mike

 

Great meeting everyone also, it was fun. I'm just a little jaded after driving Seal's ride ...hopefully I will catch up soon .

Steve

 

if both cars run pump gas then the difference will be roughly the same.... but if you go past 1.2 bars watch out. A fully built 20g runs high 130s... a 18g low to mid 130s... pure and simple... i doubt you will find a 20 g set up as they are scare ....
nice runs...
markski

 

It seems I recall a conversation involving you NOT driving any other cars that had more than a flash? Start reaching for your wallet and be done with it...

 

Thanks Mark, that's good to know and thanks for the comments. I'll PM you..

 

Yes I did say I wouldn't but the suspense was killing me after a while and I caved . I have to be extra nice to the wife for a few months ...then I should be in business...

 

Car mods... sewing the seeds of marital discord since the dawn of the automobile age.

Glad to be of service on the test-drive.
