    exactly how much top end does 3:55's kill?

    Re: exactly how much top end does 3:55\'s kill? Onerareviper, That is great information but the real benefit only really applies to first gear. What is not clear in this article is that when you shift to the next gear (earlier with lower gears e.g. 3.55) you now have LESS torque until the car...

    VIPAIR™ Dyno Results on 99 RT 16 RWHP!!

    Re: VIPAIR™ Dyno Results on 99 RT 16 RWHP!! I'll jump back in on this one, why I don't know because I don't have any vested interest in Vipair. I am just trying to help those interested understand the ram air/cold air theory. RussM, thanks for doing some testing! I did some math on this in an...

    oil starvation on the track

    Hoosier Daddy, I just hope all these people short shifting at 4000 rpm are not in our run group! Pete, I would get the big pan and ACR oil filter adapter for sure. The Accusump is good insurance. Regards,

    VIPAIR™ Dyno Results on 99 RT 16 RWHP!!

    Re: VIPAIR™ Dyno Results on 99 RT 16 RWHP!! Matt M, The Vipair pulls air from in front of the radiator after it has passed through the grille opening in the fascia. At this location the local air speed is very near zero and the pitot tube example applies. The Vipair does have a small opening...

    Re: VIPAIR™ Dyno Results on 99 RT 16 RWHP!! I know this is all about being the longest post and I have not read all of the replies so the answer may be in here somewhere. But based on the last few pages I scanned where technical assumptions are being made, it looks like the jury is still...

    looking for a stronger crank damper

    ab, ATI makes probably the best dampers. They make one for the viper (Gen 1 and Gen 2 are the same). Expect to pay around $400. Here is the link: http://www.atiperformanceproducts.com/products/dampers/charts/damchrysler.htm Regards,

    HP Gains

    mntngts99, I think enough people have tried this (on a dyno) and found the 58mm TBs work best until you have around 500 RWHP. Then a jump to 65mm makes more power. With big HP numbers, the 70mm TBs can work effectively. You need to keep up the velocity through the TBs, so on a fairly stock...

    Finally!!!! I just got the Fall edition of Viper Magazine

    Peter-RedGTS'98, Ashley (Page 9) is my daughter and she already calls it "Her Viper". She loves to wear her fire suit and drive around in the pits. She is always asking "Daddy, when are we going racing?". Don't think it was her fault the magazine was late though. Best regards,

    Header Wrap

    Mark, The factory heat shields fit over the TNT headers without any modification. With this set up, I have never had any heat related melting issues under the hood and have been known to drive the car quite hard from time to time. :D Regards,

    Timing chain and gears

    XLR8, Not that I am putting a cam in my car or anything because it is bone stock, but I just purchased a Cloyes True Roller Hex-A-Just timing gear / chain set from More Performance (704-393-8241 www.MorePerformanceInc.com). Their Part number CLO 9-3152A. It was $189.00. Of note, it uses a 3...

    What splitter is this?

    That's Paul Schley's car. The splitter is from McCann and the vertical (black) piece with the brake cooling ducts that integrates the splitter into the fascia was made by Erik Messley. You can reach Erik at EMI Racing 714-713-9096. Regards,

    Possible replica of ORECA GTS-R front fascia, anyone interested?

    The Autoform fascia has much smaller brake ducts, otherwise very close. Please keep me informed. I may be interested in one without the driving lights. TNT, Archer, Autoform all sell the center louvers seperately. It is very expensive to have them installed properly in a stock hood. Autoform...

    Re: Sport Compact Car Paolo, I remember last year Wayne talking about a very key point being the driver. I have no idea what your experience is on road courses (please don't take this as criticism if you are great), but for something like $500/day you could have Erik Messley drive your car...

    Hood Cut-Out?

    Don't worry about the dremel, etc. Go buy a hole saw the same diameter as the hole on the right side (fits in a hand drill, with pilot bit) at home depot for $15. One cut and it is perfectly round and sized. This is what I did and it worked great. Regards,

    What are the best pads on the Stop Techs??

    Docta, You might want to check with StopTech or maybe Ken Adelberg about the PFC 01's on StopTech rotors. I really like the 01's but they seem to eat my StopTech rotors alive (severe cracks after 4-5 track days). The StopTech guys have looked at my brakes and said the pads (01's)are too hard...
