TX2K14 TEASER: 749 Horsepower and 818 ft-lbs of Torque

**Arin@APR** · 03-12-2014 08:36 AM

We're taking the RS7 to the TX2K14 event this weekend and decided to give it a little more juice.

We removed the cats, loaded it up with 104 and dialed in more power. Everything else is stock, including the cooling, exhaust from the catalyst back, intake and filter, etc. The car will also run at the event with everything else stock, including the tires, wheels, full interior, etc.

The end results was 680 AWHP and 775 AWFT-LBS of torque. We estimate that to be 749 Horsepower and 818 FT-LBS of Torque at the crank.

Hopefully it's quick and turns a few heads! Just for a frame of reference, we did 10.6 @ 129 MPH with only 93 octane and stage 1.

The chart shows figures at the wheels, crank, and our estimated drivetrain loss

**Ynnekdude** · 03-12-2014 08:45 AM

Absolutely mad. What a monster. I take it the stock RS7 exhaust is pretty efficient in its stock form? I have no doubt this car is going to see 9's with minimal modifications.

**Arin@APR** · 03-12-2014 08:50 AM

We haven't played around with the full exhaust yet, just the cats.

**65vetteC6** · 03-12-2014 08:50 AM

F*** these cars are going to be nuts after a few years of development.....even more nuts I mean.

**CreoSTi** · 03-12-2014 09:05 AM

G'luck this weekend!

**TheChef** · 03-12-2014 09:07 AM

See you there APR ;)

**StevenH** · 03-14-2014 07:59 AM

Great numbers! Why are you assuming such low drivetrain loss? That is under 10%. I would think AWD + a torque converter would be in the 20% ballpark putting this around 850 CHP.

I don't believe in percentage based drivetrain loss calculations, but feel free to use whatever number you want based on our AWHP figures. Also, for what it's worth, from what I've seen, the new ZF transmissions are extremely efficient compared to other transmissions in the past. Could I be wrong? Sure! But, at least I think my estimations are a tad on the conservative side.

I actually just wrote some information about calculating drivetrain loss on the link below. It's a different platform (4 cylinder, manual, front wheel drive ---- far less losses than an 8 cylinder, all wheel drive, tiptronic), but the concept still applies:

How does the car sound vs stock with the cat delete???

**LINDW4LL** · 03-14-2014 10:15 AM

I saw that it put down 619whp at TX2K.

**Arin@APR** · 03-14-2014 11:19 AM

Yup!

Results so far listed below.

This is a mix of 2WD and 4WD vehicles. The 2WD drive cars are on the dynojet (which apparently reads higher) and the 4WD cars are on the Dyno Dynamics (which apparently reads lower).

Not bad at all.

Not the best video in the world, but you get the point. it sounds awesome.

That was awesome!!! Im getting my car next month and will do the tune and the cat delete. How much do you think you gained from the cat delete?

Not sure, but we have something better planned in that department, and I'll have before and after results to show you. : )

**Arin@APR** · 03-14-2014 02:15 PM

Still doing pretty well!

**sciblades** · 03-14-2014 02:29 PM

any chance they gave you the chart from their dyno? Would love to see it if they gave that out.

good luck tomorrow you guys doing dig and roll or just dig?

**Arin@APR** · 03-14-2014 03:27 PM

Nobody sent anything to me so I don't know.

We'll be drag racing tomorrow. : )

**Arin@APR** · 03-15-2014 10:58 AM

Dyno video is on our Facebook page.

The drag strip was canceled for weather. If the guys can stick around for another day we should get runs in tomorrow.

**Packy** · 03-15-2014 08:11 PM

Mustang 5.0 400.89 lol. I guess with Fords you gotta give it every little bit you can. Maybe a little wax on the inside of the intake for sliperyness will add the extra .11hp

**S7_UAE** · 03-15-2014 09:11 PM

Thats really great, All the best..

It's funny that the crown vic is one of the top 5...

**dem00n** · 03-15-2014 09:35 PM

4.6L V8 isn't that funny.

Big and comfy cars, big engine. It's about as American as it gets with those crown vics.

**S4Q8** · 03-15-2014 10:45 PM

This is just freakin awesome !!

We are waiting for the S7 Cat-delete

Im sure they are all interchangeable S6/S7/RS6/RS7.

Goodluck on the strip !!

This about sums me up while waiting for updates and videos in this thread:

I just noticed that there is a Lexus IS 300 with 861 hp on that list...yikes....

**Arin@APR** · 03-16-2014 04:09 PM

No drag strip. Got rained out.

Videos will be next week if we have any good footage. The guys are driving back now.

I think it has an LS3 swap in it. At least my guess is that its probably the one from the 1320Video youtube channel

Did you guys forget that IS300s have the NA version of the Supra turbo engine? I have a supra turbo bottom end on my IS300 and it puts down 420 to wheels on a PTE 6266 turbo with a conservative / "lower boost" tune. An IS300 (with the right work / setup) can make just as much power as a supra

No, I didn't forget the IS300's powertrain similarities with the MK4 Supra, I just recalled I had seen an LS3 powered IS300 that has been associated with previous TXTK events, so I drew that conclusion.

I then just did minimal homework and looked at the owner's name next to the IS300 on that whiteboard which reads "Matt Owen" and a quick google and youtube search shows an LS3 powered IS300 owned by a "Mathew Owen" who has in fact been in several 1320Video clips as well as previous TX2K events, and is from Texas. I could be wrong but I could have sworn I saw it in a recent 1320 video in one of their "cash-bash" events sporting a turbo, though I have had trouble finding it this evening.

So I was not implying that an IS300 is only quick with a motorswap from another platform, but rather I recalled seeing an LS3 powered IS300 associated with this event in the past. So I made an informed guess to speculate as to what the car on that board had done to it.

Quote from Matt about his choice:

The idea behind this swap was really based around parts availability. At any given moment I can browse through hundreds of parts for sale on either my local craigslist or automotive forum. With tons of options, parts availability, great power curve and reliability the GM LS based engine was a solid choice.

Now does that make me a GM fan? No I've owned a handful of MKiv supras and have a deep love for the 2jzgte. Does swapping a cheap readily available engine into an affordable tasteful sedan make a good business model? YES!

So next time please dont come in here assuming we are all uninformed idiots.

I dont know why youre taking offense to this... i wasnt implying anyone was an "uniformed idiot".... im sorry if it came across that way. i know people have done LSx swaps in IS300s... most of them being in 400-600whp range... so when youre talking an 800+whp IS300 most people who are familiar with platform, including myself, would assume its running a 2JZ-GTE and not really be surprised that it can put out that kind of power. you obviously care a lot more about this than i do brother, and did more "research"... good for you, you proved me wrong. can we just agree that there was some misunderstanding/ miscommunication and move on? im not here because i need to prove something

**getslideways** · 03-16-2014 09:44 PM

I took your comment as being partially directed at me since you chose to quote me in your initial reply. So I was responding with evidence about this particular car in question to support my initial guess. However, yes you are right, that in general IS300s posting big power numbers more commonly come in the form of a turbo 2JZ, but that seems like it may not be the case with this IS300.

So I posted my reply with evidence to show I was not making any uninformed generalizations, or speculations regarding this specific vehicle. Instead I posted my guess based on the previous knowledge of what I knew about Matt's TK2K IS300 from footage and threads from earlier years. So my guess wasn't posted from a lack of knowledge about IS300s and 2JZs but from a specific knowledge about what I believed this particular vehicle to be. That is what I was aiming to clarify with my previous post, that there is a good chance this IS300 is something much different and far more uncommon.

A few notes from the event....

...those dyno's where reading very low and where killer. 618 wheel on the RS7 was awesome. For perspective, a friends Alpha GTR that put down 1100 on an alternative dyno 8 hrs earlier put down 970 on this.

...Jessica Barton won the contest with 1300 wheel on her Supra.

...rain was torrential Sat and Sunday and everything was rained out.

...had a great time meeting Eric from APR for the first time and we where able to lay some good ground work for my S7.

...and a few quick photo's from the event, one with the APR RS7 and showing there with HRE....
