I have been dealing with Champion Motor Sports for about 2 years now having become interested in bldg Porsches versus my (Sold) Z06 of 900 WHP and 800 FT#. The Z06 build was successful but nothing short of lies and deceat placing me in a position to oversee every last nut and bolt added to the car. It ended up as a great success due to my insistance on quality and performance. CMS has been nothing but straight-up tempered by integrity and a keen focus on my best interests. I can assure you if Tom posts something all need be done is a simple explanation (the run files are a result of the clutch cooling but further yet the files displaying slippage are due in part to the fact that the car is putting down enormous power). Once we corral that power with an upgrade in gearing, the clutch, and a possible engine build it will prove to be a pinnacle (for street cars) for many to reach.

 

Thanks Shotcaller. The 750whp run was on race gas and 2300mb of boost.

Slowcart...I'm not sure why you would think there's some sort of trickery going on here. We did a baseline dyno of the car when it arrived a week ago (runfile 4). Then it came off the dyno so that we could install the hardware. In the meantime there were other cars on the dyno (like one of our 68mm Billet tirtronic cars). We put the GT2 back on the dyno when the hardware install was complete. On different days, the the runfile numbers reset. Each time you shut down the dyno software, they also reset. I can assure you...it's the same car. Not sure where you're located Slowcart, but you are more then welcome to come to our shop and see the results yourself.

If it's not the GT2, what other 750whp car would it be?

Thank you sir. We're all very excited about this build. As I've always stated before...we have an open door policy at Champion Motorsport. Anyone who questions the quality of our work or the integrity of the results is always more then welcome to visit our shop and see it with their own eyes.

I will personally give the tour.

 

2.3 BAR!?! On a stock motor?? That explains the peak HP.

Props to you for being honest, but damn!

 

You sure it's not 2300-800=1500 mb?

 

That's 1.3 bar. Its pretty low boost

 

Nice numbers! What are you all using to monitor the boost? IIRC factory MAP cuts off at around 1.55bar which is always funny that people claim that's the boost they run because they don't see a higher number. If you are using the Durametric or a PWIS to log would make the 2300mb around 1.3bar?

I think that would put those turbos up with the power of GT35s at that same boost, which I highly doubt considering the compressors in the GT35 are a bit bigger

 

If Tom is reading millibar off Durametric, he'll have to subtract ambient pressure (usually around 800-1000 millibar) to calculate demand. But I could be completely wrong.

 

I always do -1000 per multiple tuners. If there was no external boost gauge they are going to hit 1.55bar and peg out/hold. Not that it's being done here, but it's often used (at least what I've seen in the 997TT world) to fool customers to the idea they are only running 1.55bar peak. I swear by a real boost gauge from an external source to see where I really stand.

 

Exactly.

Or...if they posted a datalog we would know this for sure.

 

I agree, I am in love. Beautiful looking hardware. Good luck with the build

 

Yep. The most it shows is 2555.00.

Exactly. I don't buy for a second that these turbos are flowing more than GT35s.

 

Very interesting staff, congrats to CMS

 

Nooooo......lol. It's actually only about 19 psi. You have to deduct about 14.7 psi for atmospheric pressure at sea level.

I'm totally sorry for the confusion. In the future I'll do the conversion before posting, and I'll post the psi number instead.

We're using the GIAC datalogger. It reads in mBar, but as I mentioned above you have to deduct basically 14.7psi for atmospheric pressure. On these runs we spiked at 21psi.

Correct.

Why don't you believe it? These turbos were tested by Tial before they released them to us. They don't make turbos unless they work. The proof is there. If you don't want to believe then I'm not sure what I can do to convince you. So far these 68mm turbos have been responsible for 788 whp on our 6 speed 997 Turbo at 23psi (**EDIT**...I correct myself, it was 25psi on C16), 688whp on 4 different 997 Turbo tiptronic cars at 23psi, and now 750 on a GT2 with 19psi (spiked to 21).

I have not seen any other tuner post dyno results of the GT30 or 35 kits recently, so I don't know what power they're actually making at the wheels, but I'm sure if they knew they could have made that power and kept VTG functionality....they would have done it too

I have an idea. Shotcaller. You are local to us, correct? How about you come by the shop Tuesday when I'm back in the office and I'll take you for a full tour. If the GT2 is still there you can even check it out with your own eyes. You can then come back to the forum as a neutral third party and report back on what you see. Maybe we can finally put the skepticism to bed. Lunch will be my treat.

 

No need to make it complicated. Next time just say "1.3 BAR". The 14.7 psi of atmospheric pressure doesn't count as "boost".


I have no dog in this fight, so I'll keep my thoughts to myself. Until then, I look forward to seeing 60-130 and 1/4 mile results.

 

Hey Tom: Hopefully the GT2 will be in my hands for the 1st break-in. Mr. Shotcaller can wait until we insert the new gears, Clutch, and possible engine (internal) build.
