1,000 hp Twin-Turbo Dodge Viper TA




Over 1,000 hp V10 engine, in a RWD car with a six speed manual. This car also happens to be a Viper, one of the most charismatic cars on the road. This is the work of RSI Racing Solutions through their RSI Twin Turbo Race Systems kit. Starting from $89,950 on top of the price of a Viper, the kit brings Precision 72 mm turbos (76 mm are optional) with custom associated plumbing, cooling, intake and exhaust. The kit also brings built forged block and internals with a 528 c.i. (8.7 litre) stroker kit. The heads and valvetrain, fuel system and clutch are also upgraded to handle the newfound horsepower. The transmission, clutch, differential and axles can also be built to handle the added grunt. If that's more than you'd like, you can forego the built block and heads and go with smaller, 62 mm turbos along with their plumbing and cooling and upgraded fuelling which starts at $44,950. This kit, called RSI Twin Turbo Systems is good for over 850 hp at the wheels. Awesome. Check out the video to see a Viper TA with the big, Race Systems kit, run on pump gas. 




Someone wasn't happy that Car and Driver posted this, though. He commented on the post and said:

"This is a commercial and NOT car news. And a 1000+ HP from a large turbocharged V10 is certainly not impressive when countless modified compact cars deliver similar power from small engines. This demonstration is embarrassing, with a car running like s**t."

The vast majority of car news come from press releases by manufacturers or aftermarket parts producers. I don't know what makes this less worthy. What makes it news is the fact that it is new information, not that it is produced for the purpose of generating interest in a product.

The running like crap part really gets me. Someone commented on the car shooting flames and sounded like it is misfiring so I'm guessing this is what this guy is going by as well. The first shot showing backfires is clearly revving while standing still, indoors, and most likely was temporarily tuned to shoot flames on purpose for the video. The other shot that sounds like backfires is while launching and bouncing off the limiter. Other than that, the car sounds good and at approximately 0:50 in the video, the car is pushed, you can hear it clearly from inside and it sounds great. Although we can't see a/f ratios, the dyno graph seems to be nice and smooth as well.

The worst part, though, is the argument about getting only 1,000 hp from a turbo 8.4 litre V10 and how it's unimpressive and unworthy of reporting. He then goes on and implies that a 1,200 hp Civic should be more worthy of reporting by saying this should be posted in a "Euro/Asian tuning magazine with the title:" American performance company gets 1000HP from a turbocharged 8.4 V10", next to an article about a few college students who got 1200HP from their modded Civic." I don't think I've ever seen or read about a Civic putting 1,200 hp to the wheels, and certainly not by a few college students. Not to mention, a Civic with anywhere near that much hp would be far less drivable, require much more maintenance and has a power delivery that's as linear as a light switch when compared to this. That's all beside the point, though. The guy completely misses the point of the video which was clearly made to excite not impress. 

Yes, a Civic with anywhere near 1,000 hp is impressive but that's not the point of the video. The same kit promoted in the video is capable of making over 1,500 hp to the wheels on E85 or race gas which is nearly 1,800 hp at the crank based on 15% drivetrain losses. They didn't post that dyno, though. They posted the one about the performance when running on 93 octane pump gas. The "accessible" performance. Not every one wants 1,800 hp. Not everyone wants to worry about E85 or have to find race gas. The video shows 1,043 hp to the wheels on the dyno, which is 1,227 hp at the crank, nearly twice the stock hp. Forget about being impressive or reaching the potential of the engine, that is certainly something to be excited about. I can certainly understand that the Viper is not everyone's taste but if you can't get excited about a 1,200+ hp twin-turbo Viper, with a V10, a six speed manual and RWD, you are not a gearhead in my book.

Michelin Pilot Sport Cup 2's vs Bridgestone Potenza RE-71R's

I never thought I'd ever run Michelin Pilot Sport Cup 2's on my 2012 Boss 302. The cost is astronomical and they are supposed to last the least of anything comparable. So how did I end up with (nearly) fresh Sport Cup 2's? A complete fluke. I came across a lightly used set with only a few hundred miles and no track time; 305/30/19 takeoffs from a GT Performance Pack Level 2 (GT PPL2). I knew my 71R's were getting very worn before the season started and likely wouldn't last the whole season, even this short one. The price was far better than a new set of RE-71R's, a little more than half, and local Time Attack rules (Canadian Automobile Sport Clubs) recently made 180 and 200 TW tires equivalent, meaning no PAX or PIP point penalty for going with 180 TW tire like the Pilot Sport Cup 2's. I have been very curious about how PSC2's compare to RE 71R's but I stayed away due to their being painfully expensive and, up to last year, their 180 TW rating would

GTR vs Evo X vs STI: which has the best AWD system?

A few weeks ago, I made a post explaining  mainstream AWD system types and how they compare , pros and cons, etc. including some simple diagrams to show where the power goes and how much. As promised, this post will focus on specific cars and what AWD systems they use, especially ones that that have more or less been defined by their AWD systems, and the best place to start may be with a bombshell; the Nissan GT-R. Nissan GT-R (R35) The GT-R has built a reputation around having monster traction and very approachable performance, thanks to its AWD system - Advanced Total Traction Engineering System for All-Terrain (ATTESA) - and what it can do for you. But the GT-R doesn't actually use the most mechanically sophisticated type of AWD systems discussed in the previous article, namely a "true" AWD with a centre differential. Instead, it uses a clutch pack to transfer power. RWD-based clutch-type AWD schematic - Rams Eye The Track Guy © The R32, R33, and R34 Sky

How would a Mustang 3.5L EcoBoost compare to the 5.0L V8?

Ever wonder how a 3.5 litre EcoBoost might fair against the 5.0 litre V8 in the Mustang? Of course you have. Ever since Ford dropped it in the F150 (and perhaps well before), everyone has been wondering how it would perform. There are basically two camps; those who think it would be awesome because of tuneability and power potential and those who think it means the death of the V8 in the Mustang. If you are in the latter group, we seem to be good so far with continuous upgrades to the 5.0 litre Coyote and the brand new Shelby GT500 which still uses a supercharged V8 as it has been for over a decade and multiple iterations. But what if... Well, it seems we are closer than ever to finding out the answer to that question. American Trucks recently got together two crew cab, short box, 4x4 F150's but one has the 5.0 litre V8 and the other has the 3.5 litre EcoBoost V6. There has been a few comparisons between 5.0 litre and 3.5 litre EB F150's, but this seems to be the most di

Bridgestone Potenza RE-71R Track Review

2012 Boss 302 on square 305/30/19 RE-71R's at AMP - Graham MacNeil © For better or for worse, I have heard and read so much about RE-71R's. Everyone swears by the grip but complains about the wear. Generally speaking, the pros are: 1. They grip as well or better than most R comps. 2. They don't wear as quickly as R comps if driven occasionally on the street. 3. They work better in the rain than R comps. The cons were limited to overheating quickly when used on track (being an autocross tire) and wearing too fast on heavy cars like mine. In the popular 200 TW category, they are faster than the popular Hankook RS-4's and BFGoodrich Rival S's according to published Tire Rack Tests. According to plenty of reviews, they are also faster than well established R comps like R888R's (which don't seem to work too well on heavy cars anyway) and the venerable NT01's. But I was still hesitant for a while until I talked to a tire tech support gentleman
