    Southbend clutch

    Does anybody have any experience with a Southbend clutch in a Viper? They advertise that their Endurance single disc clutch is rated to 1000 lbs tq and is priced similarly to the Spec 3+. I've found next to nothing about them on the forums though.

    Did you try any runs without the nitrous?

    Roe Tuning Question

    I recently installed a DW lower pulley along with the 10# upper pulley on my Gen II. I took the car out for some logging runs today and noticed more fluctuation than I had expected in boost. Note the sharp 3# drop in the image below. Is this indicative of belt slippage?

    Thanks Jay, I'll have him give that a try.

    keys locked in RT/10

    I have a 99 RT/10, last week for the first time I had an issue where the exterior door lock buttons simply did nothing even though I had not locked the car. I had to open the back window to get in. Yesterday I had my brother transport the car for me (he owns a car carrier). I carefully...

    What mods do you regret?

    While on the subject... Has anyone done polyurethane engine/trans mounts and regretted it due to vibration? I've heard it improves shifting but I'm worried about vibration with normal driving and idling.

    Texas Mile

    Gary, Was great meeting you there. I ended up at 185.4 with my RT/10. Now I finally have a reasonable answer for that "how fast have you driven it?" question I always get. The A.R.T. car was something to see. The Viper community is well represented by David and his team, they are great guys...

    Texas Mile

    My understanding is that a lot of the real heavy hitters in the mile (UGR, Ray Hoffman, SW) bowed out after Richard Holt's Gallardo crashed at high speed last fall. Does anybody know if ART will be back with their world record-holding Viper?

    Texas Mile

    Gary, My brother and I will be coming from Minnesota. I have a 99 RT/10 (black with blue stripes), he has a Porsche 993 turbo. Won't be breaking any records but it should be fun. Tim

    Best shift RPM?

    This was in Brainerd last wednesday. My car is pretty similar to your old car with about 650/650 but the DA was at 2600 and my cleanest run was with the car pretty heat soaked. Perhaps the lower RPMs are costing me but I found that when I went higher in the RPMs the car was harder to shift...

    Best shift RPM?

    Went to the track the other days and fell a little short of my 10 second goal with a best run of 11.2@131 on a mediocre 1.84 60ft. I'm wondering if I'm shifting at the optimal RPM though. It seemed like my numbers improved after I turned down my shift light RPM a bit. On my best run I was...

    Does anyone with a GTS which they went with an RT-10?

    We live in Minnesota where nice driving weather is rather limited. The last thing we want to do in the summertime is role up the windows and put the air on, so we went with a GEN II RT/10. I agree that the GTS has a small advantage in looks, but the RT/10 is still a really sharp looking car...

    Post your Upgraded Fuel system

    From what I found researching this earlier, once you cut openings in the stock canister or bypass the check-valve at the bottom, you run into the "less than quarter tank" pick-up issue. One other thing I found out is that standard fuel line is not meant to be submersed and will fail over...

    Post your Upgraded Fuel system

    continue to run the BAP, but at a low setting I believe that if you look at the current draw of two Walbros, it exceeds what the MSD BAP can handle.

    Dual fuel pump wiring question

    Thanks for the information Tony. Are you running the stock fuel line with the twin pumps or did you go to something larger?

    That's what I expected. Thanks for the response.

    Dual fuel pump wiring question

    I'm considering running dual Walbro 255s. Will I need a separate 30amp circuit and relay for the second pump? I'm guessing I can't run them both from the existing circuit and that the MSD voltage booster I currently have will need to go. Any advice would be appreciated. Thanks.

    Calling oil/gas expert Tom.....

    Tom, Thanks for the explanation. So would a higher HTHS number within a grade of similar base stock oils indicate that more robust VMs are being used? Also, regarding the previous question on ZDDP content, I found this page to be useful for comparing Mobil 1 oils...

    Calling oil/gas expert Tom.....

    Tom, Since this is a "live" oil thread I couldn't resist a general oil theory question: I've learned quite a bit from reading your previous responses on oil threads and I've noticed that you put a lot of stock in the additive package of the oil, while on the other hand the marketing for oils...

    Plug Gap NGK BKR7E

    So did the MAP mounting cure the detonation you were hearing?

    How low do you think they will go?

    Just to put things in perspective, my brother just picked up a Ferrari 360 for around $60k. The car was worth about $100k two years ago. So the Viper is still holding its own on depreciation compared with other exotics.

    How to for Roe S/C removal & reinstall?

    Could you elaborate on this? Are you saying that fuel pump voltage may be low and causing a lean condition or that the BAP is taking the voltage of the whole system down and affecting other electronics?

    How to for Roe S/C removal & reinstall?

    My experience is that if it sounds like it could be detonation it usually is. Mine sounded like a spray of rocks on the exhaust. There were no obvious signs of detonation on the plugs, but putting some race gas in the tank eliminated the mystery noise completely and confirmed that was in fact...
