    Random Tech GTS Muffler Delete

    Any good muffler shop can do this with two 18" pieces of pipe and 1/2 hour labor. I had him put the stock tips back on. Paid $30 bucks total in 2000 for the muffler delete at my local shop. Steve

    Road Racing w/Forced Induction

    I'm not sure how to measure post SC temps with a Roe. It would definitely be better for the post SC temp to integrate seamlessly with the PCM/VEC. Although the differences between IAT and post SC temps are not linear, they are somewhat relative as regards the AFR when using the WB set up to tune...

    Road Racing w/Forced Induction

    I agree completely with the 1% of total mileage statement. We do 10,000+ miles per yr. with 100 track miles and a couple autocrosses usually thrown in. The car will never be perfect for every situation, but I would much rather focus on the 99% of driving we do than the 1%. Most Vipers and...

    More pics of Road America

    Great pictures! Definitely one of the premier road race tracks in the world. It is the fastest permanent track in the world. Started going there in 1969. We were there for the Vintage races a couple weeks ago. Nothing like the CAN AM Rolling Thunder cars. Steve

    My new Tom's 40mm rear calipers!!!

    I've had Tom's brakes for the last 4 years. I run B3s on the track and EBC greens on the street. I also removed the prop valve. The pads wear even front to back. This last Gingerman session, with front and rear pads equal at the start of the session. I actually toasted the back ones first. That...

    Viper techs

    There are no actual Viper techs within several hundred miles of here. That being said, our car has seen a Viper tech twice in 8yrs / 80,000 miles..........and only then because we were in Detroit and had the fluids changed at Dick Scott Dodge (great place!). Most of the working parts on a Viper...

    6th gear question

    I used 6th gear, with the stock rear end and on level roads, at 1250 RPM (63 MPH if I remember). for literally thousands of miles. The speed limit around here is 55 tops. Switching to 3.45s made it completely a non issue, even on hills. Adding the blower, even more so. As long as the RPMs are...

    Can Anyone Check This A/F Log

    Increasing the base injector set will richen the tune in closed loop, but I believe (could be wrong), it is also the starting point for when the VEC settings come into play and you add / subtract fuel pulse duration. Basically when you play with the base injector set, you are fooling the pcm...

    Can Anyone Check This A/F Log

    If you are just starting, I think the best thing to do is to check your LTFT and adjust by increasing or decreasing the base injector set on the fuel options page. I had to add 5% to what it came with (now at 70%). Based on plug color, the cylinder trim can be adjusted a little too, but some...

    Can Anyone Check This A/F Log

    Tune by 250 RPM increments. I have no W/M and and am tuned around 11.5 to 11.8 at WOT. You should be able to smooth the WOT line out by using the 250 RPM steps. I think you have some fuel to take out in the meat of the run, but it looks to me like your transition area may be a little lean for...

    Cup holders

    See if you can get a Mopar dealer to look this number up. mopar # 82204416 We have 2 of them in the car. Seldom used for beverages, but that's what they were made for. Heavy Viper tax. About $25 each. That was over 5 years a go. Very handy for storing stuff while traveling. We have them both...

    Blew a radiator hose ,need advice

    The clearance betwen the top radiator hose and the pulley in question is a 1/4" at best. The good thing is that the engine torques to the right. You need to rotate the hose up as close to the pulley bracket as possible. This will give a slight bit more clearance. I put a little piece of Velcro...

    driving to Detroit

    Ted has got us beat by a few miles this year so far -- only 5K here, but we've got a pile of road miles coming shortly. :drive: We've stayed in motels from here to Texas. Super 8s, Econo Lodges, Holiday Inns, Mariotts, and others. I'm guessing at least a few dozen nights the last 8 years. We...

    Gen 3 Roe Blower ready by VOI 10

    Everyone's experience may vary a little....no matter the system or mods. The GEN II issues you speak of were resolved several years ago with the addition of cylinder trim, restyled intake box, and the VEC III. They are not relevant to the GEN III product, a similar iteration of which has been...

    Gen 3 Roe Blower ready by VOI 10

    I completely agree -- minimal traction issues from a roll if using your right foot properly. PS2s made a big difference. When xcrossing, I routinely start in 2nd gear with a little tire spin for the folks :2tu: Might take a long time to wear out.....we may not need another one. I may as well...

    Gen 3 Roe Blower ready by VOI 10

    Got the graph. Thanks. A little above my pay grade, but I will noodle a little more on it. I didn't think the Roe required that kind of HP to drive it? I'd like to think the engine was designed well enough to last at least 200K miles. Time will tell. We are way ahead of most on the Viper...

    Gen 3 Roe Blower ready by VOI 10

    Thanks. We bought it to drive. No doubt about that. No W/M. (either car) I wanted to keep it as simple as possible. Plus, I can't afford to give up the trunk room. Over the last 8 years of creative Viper packing for as long as 2 weeks, ....shows that cavity holding a lot of 'stuff' Steve

    Gen 3 Roe Blower ready by VOI 10

    Ron, I certainly won't argue automotive powertrain dogma with you, but I can always use a little schooling. You can break your car loose at 60-65 MPH in 3rd.which is roughly 3100 rpm with 18" tires & around 2900 with 19" tires. Looking at a recent log, my car is boosting around 4.5 pounds at...

    NorCal Viper Club floor mats

    A little follow up on my trunk mat issue. I received a new mat today courtesy of the NORCAL club. Maurice found that the cut on my original mat was wrong and has made it right. The new mat fits very nicely and we are quite satisfied. Thanks Maurice, Steve

    Gen 3 Roe Blower ready by VOI 10

    Yeah but...I have had zero issues of the type you mention Ron. I put the 5 pounder on at 54K miles -- now a tad under 80K. The stock clutch has 50K on it now. My 3.45 Unitrax has 50K as well, Tranny is still the same as when bought. You know our car is far from babied. It never leaves the...

    I making myself available for tuning and mechanical work again.... :-)

    I have never had anything but the very best vendor back up from Sean....even with all that has happened the last couple years. He had some serious back issues along the path as well. I would never have attempted the project if not for knowing his reputation of helping his customers through the...

    "VIPER Invades Mackinac" Event

    I'll third the comments above.......Had a great time!! Met many new people and ran into a few from the IL club I hadn't seen in a quite a while. We even had Linda Vaughn in our MCVO hotel party room Thursday night for a short while and photo op. It used to be an annual event for our club until...

    Roe vs. Paxton

    Yup. the old by pass valve. Should have remembered that...but If the pulley is turning the screws, it would seem to be using HP? ...just like any of the other pulleys driving things on the engine. They all take some HP. I guess the real proof is in how long things last. I'll let my cast...

    Roe vs. Paxton

    I'm always reading your opinions. You are one of the authorities here. I think I undestand what you're saying about normal driving. Being positive displacemt, those twin screws are turning all the time pushing air in -- even with no boost. My temp gauge (170F) this last track day -- 75F...
