Looking at purchasing the Champion 65mm vtg turbo kit and looking for some feedback from anyone who has kit . Looking for vbox verified 60-130 or 1/4 run times as dyno's only tell part of the story. Any insight on this kit would be appreciated . Why better than say AWE or Evoms ??

 

Champion Motorsport uses a billet compressor housing and a 7 blade compressor wheel. Thermal efficiency is optimized- less heat into the engine. The 68mm kit is even better for airflow but boost threshold is a little bit higher.

The rest of what you seek is in the various forums. Better yet, just call them.

 

Thanks , I have spoken to them but wanted info from someone who has kit .

 

I am guessing that this has been covered previously--but here it is !!
Why would anyone stay with VTG and not use other known factors that seem to be developing plenty of HP easily enough/?
What does the performance of VTG Champion 65 and 68 look like by way of comparison to other turbos that are making plenty of HP?

 

How much HP do you want?

How willing are you to hack at your car and remove well engineered solutions just to strap on yesterday's technology without Porsche's engineered failsafes?

Champion 68mm VTG turbos flow over 450HP of air each. How much more do you need?

These are questions only the car owner can answer.

 

I agree Nick 100% but my intent with this thread was to get opinions on champions 65vtg kit versus the 68vtg as I am looking at getting the 65 kit ( as not wanting to go with cat less exhaust , upgrade clutch again along with much more expensive for 68 kit) and wanted some real time drivers seat thoughts and vbox verified times for 60-130 and 1/4 mile as heard it has done 10.6ish 1/4 mile on a triptronic? Have spoken to Tom @ Champion who is very knowledable and great in getting back with answers but wanted to do more research.

 

You don't have to go catless or get a new upgraded clutch with the 68mm kit, just get a mild tune with less boost to start, don't go hog wild and go straight to 675whp.

If you go with the 68mm kit, you will be future proofing yourself to a certain extent- when you want to increase boost you won't have to upgrade your turbos again.

In my opinion, of course.

 

I posted a thread about VTG's on 6speed so it will be recieveing more and more info as the days go by so maybe you should subscribe!

Thanks GTRNICK, I am also a member at 6speed and I will be watching that thread but to date it still does not answer my question. I am trying to decide on champion 750 hp kit (65vtg) vs Evoms 775 kit or AWE 750R kit ?? There are many reviews on people with Evoms and AWE along with vbox verified times but still looking for Champion 65vtg kit backup. As dynos say a lot , they are not the complete story.

 

Well personally I would go with neither until there is more info available.

I dont believe you can get more than 700crank out of VTG's running on pump fuel!( alot of times and power figures outhere are minipulated by dynos and race fuel )

The CMS 68mm could be a different story but we are still wating for a guy to post his info after he has fitted them.

It's alot of money to spend to get nowhere so be patient and wait before you spend you hard earned cash IMO

 

GTRNICK nailed it.. If you are running pump gas, this engine will not tolerate high levels of boost and maintain similar levels of exhaust restrictions. Be careful seeing race prep street engines with straight pipes and NO cats. I have several datalogs showing excessive cylinder knock retard over 1.2 bars of boost. To reduce the knock retard and one needs to lower boost, lower engine timing OR run higher octane fuel.

Installing a larger compressor wheel on the stock turbochargers does not leed to more power. Exhaust back pressure reductions will. Bigger overall gains can be seen when one changes the hot housings > upgrade to the larger GT2 hot housings. Please keep in mind that this turbocharger hot housing/turbine wheel is smaller than the 993TT and 996TT K16's. Power is increase due to higher boost levels.

 

Thanks Kevin

It's just I have had a brand new pair of VTG hybrids sitting here for over a year but dont want to just slap them on till I am sure I have something worth using!!!

So I have been sitting back and observing alot of info on forums instead.

What would you reccommend to do with the 997tt if you want more power?

 

Why would you want to run 675+whp on unstable street fuel? The OP already said he didn't want to change clutches, and that level of HP (albeit relatively mild) will necessitate a clutch change.

We are all talking about different things, nobody is on the same page. I have a GT2, use GT2 hot sides and Champion Motorsport 68mm compressors and billet housings. 93 octane street fuel commonly found in Florida to Wisconsin, on my street ECM, and 116 (VP C16 usually) on my high HP race ECM. The street tunes cover a range from 620whp to about 700whp, and the race tunes range from about 720whp through to about 840whp.

 

First of all here in the U.K. we have 99 octane straight out the pump!

Second of all I drive my car daily so for me to run race fuel on a daily basis I would have to own my own oil refinery lol

And thirdly you are on a different page to myself and I think the guy who started the thread so i agree with you there!

nice car and build by BTW

 

Just for clarification, I have a 2.5 sachs clutch, awe i/c, Gt3 tb, Awe plenum, europipe exhaust stg 1 and awe/ giac tune which is approx. 625 hp. I am looking at getting more torque and hp which the dyno for the vtg 65 shows. I agree that I need to get more info before I decide .
