Any dyno results from the Europipe vs Tubi Catless?

 

We're running the car thing morning...hang in there. Unfortunately, the installer who installed SDG's EP exhaust cross-threaded both pre-cat O2 sensors so they were too damaged to re-isntall and we needed to order two new replacements. They just arrived and we'll be getting the dyno runs done asap. Stay tuned...

 

Tom is correct. Champion had to fly in two replacement sensors as the original sensors' thread was stripped by the original installer. That caused the delay. Given that the threads were stripped they could not be screwed into the Tubi catless race exhaust. Would never have known had I not switched exhausts. They were functioning fine but with no thread could not be reused. The installer will reimburse me for the cost of the replacement sensors and shipping.

A little frustrated that I cannot get the car back in time to compete with it in the Sunday's racewars roll races at Pocono Raceway but that's most certainly not the fault of champion. I'm happy they discovered the problem before the sensors fell out at some point had I kept my Europipe.

 

Warm up tire process I do:


TC off, sport +
Pull around water box then back up almost to it
Stomp on accelerator. All 4 wheels will spin (I've done this at the best prepped tracks in the country). Key is to be right after the water box and before the line which is usually prepped well.
You will feel when the car hooks then let off and brake quickly
Back up to the lights and stage
Enjoy added traction


I've tried every sort of trick possible on several different dual clutch/awd cars and this is the best for me. I've done it at Atco and Englishtown tracks and every single time have dropped a minimum of .1 from my 60'. On average this has netted me .2 and greater than just pulling up to the lights and doing a LC event. Let me see if I have a video
When doing the above process, I do not use LC btw. Any questions PM me

 

Bad break on the o2 sensors. Sorry to see that but glad you got it sorted out and will also be getting reimbursed

 

Thanks. This is one of the reasons I shipped my car to Champion for all of this work. For this much work especially the intercooler install I wanted Champjon to do it

 

Man that sucks. Glad to see Tom got you sorted. Can't wait to see you put the beast down the track!

 

Thanks Sam. Tom will post Dyno graph shortly. But I will say is that I'm extremely satisfied with the results on the Dino. Tremendous gains in horsepower and torque. Can't wait to see how she does in the real world though of course

My only remaining limitation is tires. I am running MPSS and don't have a set of drag radials or R compound tires for events.

 

OK...results are in. Here is a graph showing all the stages of SDG's car since it got here. Here's a breakdown:

• Runfile 005: GIAC Stage 2 with catted exhaust. This is how the car arrived to us.
• Runfile 010: GIAC Stage 2+ with Champion Intercoolers and catted exhaust.
• Runfile 001: GIAC Stage 2+ with Champion Intercoolers and Tubi Race catless exhaust.

Conditions for testing were nearly identical for all three stages. All tests were performed using 93 octane Mobile fuel. Overall we're really happy with the results. Since the car arrived it has picked up 45hp and 62tq at the wheels...a pretty solid gain! There were a few cat-less runs where tq spiked a little higher then 577 but this run was the fairest comparison. One of the things we're real happy with is the smoothness of the HP curve in the upper rpm's, which is a notable change from going cat-less.

 

Looks like the catless should really perform well at the track.

 

Definitely shows nice consistent gains up top. That's where cats show their restrictiveness the most.

 

Wow the gap between power produced by catless vs catless really grows at higher rpms.

Tom besides the different in peak power and torque, what the greatest gain in relative power and torque and where does it occur?

 

The graph sure does look that way. I know Karl911 was very happy at how his performed on track

 

Definitely. Even after consecutive runs in our sauna room, I mean dyno room, IAT's never went higher then 40-41 degrees celcius. With factory intercoolers we were seeing anywhere from 58-62.

 

Very nice guys congrats!
