John? If so, then yup.

 

Tom and team took my car 2 years ago and transformed it. He can list out all mods, some a little over the top, but fun! I'm flying down to So FL to drive it home after the open house. Tom, you guys are welcome to Pbox and post any numbers you like. Champion runs a first class operation; from R&D to customer service. They have been fantastic to work with the last couple years. Attached is a photo of my car at Champion with some their other eye candy parked behind me.

 

My brother and I cant wait to have our CMS 65mm turbos completed and installed.

Kit seems nice. What are your thoughts about keeping my exsisting exhaust with the kit EP2? Also, is the kit avalible not including the exhuast if it is an option?

 

For our 65mm kit, I'd say you'll be fine with the EP2 exhaust. They make a great exhaust for sure.

But if you're thinking about doing the 68mm kit, you'll definitely need something without cats. At that power level, there's just no cats that flow enough..even 100cell.

 

Very interesting and makes sense. Thanks for sharing your experience.

 

Tom,

You input is very valuable to me. I see you have a kit for 65mm, not 68mm.Why would I be thinking otherwise? Is there a 100mm kit? Could you outline the power gains with just the 65mm kit vs. the 68mm kit? I understand that numbers on a website can be kind of sensitive but, they are, only if they are under quoted, also, keep in mind I am at 1 mile high alt.

Everyones help is appreciated,

 

At the end of the day, who has created the best kit out there? Anyone one have dyno results or detail tracktimes over a stock application? At thispoint I am thinking just turbo’s and intercoolers, possibly the throttle body also. As os now IMO Champion has the best results but, others do claim more?

My intention was to get away from the stupid hype though. What’s reality?


<oShould I forget this and move to a Gallardo with TT? </o

Elite, AMS just released their new kit and it looks promising with great numbers;

I'm partial to the Gallardo TT myself and will be building one.

 

Yes...we have both a 65mm and 68mm kit. That number (the "65" or "68") represents the size of the compressor wheel at the exducer. (see pic). Keep in mind that our turbos are also unique in that we are the only ones using a dedicated billet aluminum compressor housing in place of the factory cast housing. This is to optimize flow and efficiency.



With either of our kits, we only quote power numbers at the wheels. Trying to figure out crank HP numbers leaves way too much room for interpretation (and exaggeration). So, with that said, here's what we get for power from each of our kits.

• 65mm -- Between 580 and 600 whp on pump gas, 610 - 615 on race gas
• 68mm (with stock engine) -- 650 - 660 whp on pump gas, 675 - 685 on race gas
• 68mm (with built engine) -- 765 - 775 whp on pump gas, 785 - 800+ on race gas.

Hope this helps answer some of your questions. Feel free to let me know if you have any others.

 

Tom, your 65mm kit comes with either the catted Tubi or the catless Tubi exhaust and I understand that your customers can use their non-Tubi exhaust as well.
But for your 68mm kit you recommend a catless exhaust only, is that correct?

 

Hi Stef....yes that's correct.

I have used the catted Tubi with the 65 kit and while it does sacrifice a little power, it still works OK. The Tubi uses 200 cel cats, so maybe your EP system with 100 cel cats would work better in that case. But with 68's we really recommend no cats at all.

 

So what is the maximum backpressure of your 200 cell Tubi and catless Tubi exhausts?

 

Stef, is back pressure linear? For example, bigger turbos create more air flow, is back pressure directly proportional to the exhaust flow, or is it more exponential?

 

The only way for this measurement to be relevant would be if we compared several different exhausts on the same car with the exact same turbo setup. Every engine and every turbo setup is going to generate different amount of backpressure.

We have tested back-pressure on the Tubi Race (catless) exhaust with our 68mm VTG's and were very happy with the results. The car was running about 675 wheel horsepower at the time it was on the dyno, and we only saw a maximum of about 20kpa (about 2.5-2.6 psi) of backpressure. We also test with straight pipes (0 backpressure) and found that the car lost spool time and significant torque. That's why the Tubi Race system has a very carefully designed center muffler which is different from the normal catted street version. Straight flow but with a nice sound. People love to criticize our Tubi Race system...but not many people realize how much R&D WE here at Champion did to make sure that is simply the best performing exhaust for anyone looking to make power on the 997TT.

Here's a pic taken during our testing... (at this location, atmosphere was around 30)
