| oFollow up on the SCT Flash Tool: real horses, real torque |
After a few computer glitches, we got some real grunt out of my Viper. And not too much money out of me. by Sonny Stone At last Dyno Day I planned to put my 2002 RT/10 Viper up on the drum and test the new SCT Flash Tool first hand. Dan Lesser, our Technical Director wrote an article about its capabilities in the last newsletter.
DYNO CHART 1 This is my old Dyno chart from April, 2004. We did 3 pulls, about 30 seconds apart. Note - all 3 runs showed similar HP and TQ. Best numbers were 416 RWHP, 455 RWTQ. This was with smooth tubes and S&B cloth filters (clone of K&N). To determine how much that represents at the crankshaft, simply multiply by 15 percent. It is generally estimated that the Viper loses 13% through the driveline, so to calculate the multiplied inverse of 13% you have to add 15% back on from the number measured at the wheels. Example: 100 hp engine will show 87 HP at the wheels or 13% loss. Take that 87 and multiply by 15% you get your original 100 HP (accurate to within 1/20 of 1 percent). STOCK: Gen 2 Viper engine should show minimum 391.5 HP at the wheels. Multiply this by 15% and get your advertised 450 HP. Most tested Vipers ran at least 391 RWHP - 417 RWHP bone stock. WITH SMOOTH TUBES & FILTERS: On this first chart, my measured 416 RWHP multiplied by 15% gives 478.4 HP at the crank. A gain of 28 HP credited to smoothies and filters - about what was promised by Sean Roe and other tuner/vendors who sell these items. THREE YEARS LATER In the interim I added Hi Flow cats and Jessel Roller Rockers. Naturally I was quite anxious to see where the engine was at, as it seemed to be running very strong. The next chart will show what they added PLUS what we got from the SCT tool.
DYNO CHART 2
Now things get interesting! The green lines show my pull on May 4th. That shows what the Hi Flows and Roller Rockers did. 429 HP and 455 TQ. A nice, modest peak gain of 13 horses but no peak torque gain. Then, on May 17th, we switched in new spark plugs and wires (Quality wires from Adam Brennan: www.qualitywires.com). Now look at the red lines. HP stays the same but look at the TQ: A gain of 6 peak lbs/ft. But there are significant gains well before the peak, from 2,000 to 4,000 rpm. Guys, keep your plugs and wires fresh! Then, Dan got started mixing better fuel to air ratios and we got numbers I’m much happier with and he also smoothed everything out, shown in blue: 447 RWHP and 486 RWTQ. These translate to 514 HP and 558 TQ at the crank. Good numbers for a GEN 3! Absolutely fantastic for a GEN 2, especially below the power peak. This is on 91 Octane. Dan also created an extra program that can use 93/94 octane. That should also realize some significant extra whack. Remember, I don’t have any aftermarket exhaust except for the hi flow cats. With headers and proper free flowing cat back exhaust I should add at least another 20 HP and 20 TQ, probably quite a bit more. A full, free flowing exhaust will add power on its own, but also increase the power gains of roller rockers and hi flow cats as well. But I choose NOT to do exhaust cause it’s too freakin’ loud. Dan Lesser tells me it’s only too loud for old farts, like me. I tell him, it’s possible. Or maybe too loud exhaust is perfect for young dorks, like him. Ahhh the joys of bench racing, boasting rights, and parking lot posers … In closing, some of the very best gains made by the SCT tool in combination with my other mods are in the lower and very hi rev ranges. Look at the HP on the second chart at 6.25K rpm right before we shut it off. It’s at just over 400 RWHP. Then compare this to the first chart: same revs and it shows about 350 RWHP. That’s over 50 HP gained way up at high revs. You feel that my friends, in the seat of your pants. RECAP: STOCK:

| Passenger 'moons' at speed camera |  |
I couldn’t make this shit up if I wanted to - From the BBC NEWS A front seat car passenger was photographed baring his backside at a speed camera in Northumberland. Safety campaigners have labelled the man as a "fool"
Red arrow indicates the offending passenger in all his glory. Before you figure that this actually might be dangerous, remember, in England they have right hand drive. So, no doubt the driver was in control at all times. This story got a million laughs in England, so your editor recommends you and your passenger try it next time to lighten up a cheesed off cop who’s stopped you in your Viper for speeding. The "mooning" man was snapped by the mobile camera as the black BMW X5 drove past on the A1171 Dudley Lane in Cramlington last month. His behaviour has been labelled as "dangerous and offensive" by road safety campaigners. Police may take action against the man for public order offences and not wearing a seat belt. Officers have the registration of the car, which was not breaking the speed limit, and intend to contact its owner. It is understood the driver will not face prosecution as no driving offence was being committed. Jeremy Forsberg, of the Northumbria Safer Roads Initiative, said: "This behaviour is simply ridiculous - it's clear what he was thinking with what he had on show. "Not only is it disrespectful, but distasteful and offensive, particularly to children who may have been exposed to this nonsense. "This prank could have been a real distraction from the driver and that is not something to laugh about." ------------------------------------------------------------------------------------------------------------

PERFECT VIPER COLOUR - EDITOR’S CHOICE Photo submitted by Sonny Stone accredited to Rocket65C on Viper Alley
I’ve seen a few cool custom Viper colours over the years. Not a ton in Canada but at every VOI and in the States especially, there’s been some wild colours. This here is the perfect one for me. I saw it on Viper Alley years ago, but could not re-find it as the poster known as ROCKET65C has gone. They turned up randomly a few weeks ago and I grabbed them. Purple is a brave, noble colour. When I order my next Viper, I would love to have Prefix match this at ‘House of Kolor’ (this is not Prowler purple or any stock Chrysler colour) and put the white stripes on. This GTS rocks.
OBLIGATORY MIKE BUCHANAN IN COMPROMISING POSITION PHOTO Photo submitted by someone who thought they had seen it all
Once in a lifetime, or at least in a newsletter, an opportunity to view a profound insight into the human condition presents itself. In this case, previously only viewed by a hardened, seasoned elite group of male Viper drivers, Mike Buchanan has agreed to let the whole world gaze at this glorious magnificence. Be it known that Mike is so tough, his forehead (arguably a little Neanderthal/Cro-Magnon in profile) can crack a solid steel Chevy 454 big block in half. That’s when Mike’s in a nice mood. THE FUTURE OF THE VIPER - ROOM FOR THE WHOLE NEST Photo inelegantly swiped from the internet
Our intrepid spy photogs have snapped an exclusive view of the new 2009 Dodge Viper. Considered the politically correct thing to do by Chrysler’s new marketing mavens, it now seats a sensible seven, has a hybrid/oatmeal turbine engine and best of all: a snazzy CVT automatic transmission with paddle shifters to simulate real fake gear shifts. Just like Ferraris and Corvettes. Now anyone can drive it. Plus, you can order one in the new trendy ‘got to have it’ spring Colours like Soft Ecru with Lilac Flower Decals or Pastel Aqua with Minty Green stripes. Matching handbags and shoes available. 2 DVD players, 10 cup holders are all standard, while they’ve eliminated those nasty oil pressure, voltmeter and coolant temp gauges - they just busied up the dash anyway.
---- IT’S STOPPED RAINING ON ALL RT/10 OWNERS: HERE’S A BETTER ROOF SOLUTION! The RT/10 factory hard top looks dorky and can’t be stored in the car; the soft top looks double dorky, takes up most of the trunk and is so ugly it deserves to be whipped daily. Herein is an interesting solution:
Anyways, the details are on his website at: As a note, lately Jeff has gained great acclaim for his Street Serpent body kit for GEN 3 Vipers. His body panels have certain design elements that I believe the Dodge styling team wishes they had picked up on. This is one of the few after market companies that actually make the Viper look better than factory stock. Mr. Lemke is certainly one to watch. ------------------------------------------------------------------------------------
IN CLOSING: CLASSIC VIPER QUOTES: TED WOODS ON V.O.I. 10:
“Anyone from our club who doesn’t get his or her ass down to Detroit for the V.O.I. 10 party will have to answer to me. Or worse: they’ll have to answer to Mike Buchanan. You’ve been warned!” Ted is the owner of Chrysler/Viper dealer extraordinaire: Wellington Motors. He is a car fanatic, friend to our club and sponsor of our website. BOB LUTZ ON THE VIPER:
“Dodge needed a car that one out of three people hated, one out of three didn’t know what it was, and one out of three people absolutely had to buy it. If we can get 1/3 of the market of people who absolutely have to buy our cars, we hit a home run. If people say it’s a nice car, we haven’t got a chance.” Bob Lutz got it. Chrysler needs him. We miss him. ------------------------------------------------------------------------------------
