    Press may not be nice to the 08 viper

    I ran into a couple of writers today from C&D magazine at my new place of employment. I asked how their tests went on the '08 Viper and they said it's the fastest car they've tested. They didn't elaborate on that but I want to see the article next month. There will be another Viper...

    Should I Upgrade to an 08

    I've driven the '08 before I retired and it is definitely a better driver than the '06. The transmission is so nice compared to the earlier cars. And the engine is well behaved at low speeds and when you unleash it with the throttle hang on. It pulls strong right to the rev limiter. The...

    2008 Detail information

    The exhaust manifolds could be better but the package is very tight when installing the powertrain into the vehicle. A lot of work went into optimizing the design but there is no comparison to a set of headers. Some engine calibration work will be needed to run headers on this package...

    dyno numbers........the king lives

    I'm sorry I let the cars out with that tune but I can't let the cats meltdown. You folks need to remember that air/fuel ratio is rich for a reason not because SRT is getting kickbacks from OPEC. If you hold the engine at WOT @ 6000 rpm until the EGT's stabilized (it takes about 60 seconds or so)...

    Best A/F Ratio

    I can't speak positively or negatively about the aftermarket units. I've never had the need to use one.

    Best A/F Ratio

    I've just retired from the SRT group after doing Viper calibration work for the last two series of engines and here is how it is done; The best A/F ratio to use will be the one that makes the most power, typically between 12.5 - 12.8, WHILE keeping the EGT's under 1600-1650 degrees at the...

    alignment specs and Oil Filter

    I did an awful lot of work to resolve the oil system issues for the 2006 engine and this new filter 05037836AA is the outcome. The 090 just does not do the job for the Viper with its high oil flow rate.

    alignment specs and Oil Filter

    The correct Viper oil filter is 05037836AA. I highly recommend this filter for any Viper.

    alignment specs and Oil Filter

    I did a lot of filter testing last year on the Auburn Hills dyno after some problems arose. A different filter is spec'd for the'06 Viper.

    alignment specs and Oil Filter

    DO NOT use the 090 oil filter. A different filter has been spec'd for the Viper because of some issues with the 090 in the Viper application.

    Dyno ?

    It depends on what you want to do with it. If you just want to generate numbers and not do any tuning a DynoJet is fine. If you want to do tuning a dyno that can hold the car at a constant load or speed would be a big plus. I've used the Mustang dyno and it worked well for tuning but...

    AEM Settings

    I'd like to see a good running AEM-equipped car. I wish I had a car to play with to see how difficult it is. I work with calibrations everyday and it is sometimes very difficult to get things working exactly like I want because of the interactions between diffent surfaces in the software...

    difference between gen 1 AND 2 BLOCKS ?????????????

    The Gen 1 has removable wet cylinder liners (known as the "heavy-weight" engine). Gen 2 started in '96 and I believe were only installed in coupes and the roadsters still getting the heavy-weight until '97. Correct me if I'm wrong please.

    600hp Hemi V-10 for the new SRT Coupes!

    It was mainly installed for the Quad Cab SRT-10 truck. This vehicle has towing capability and the sensors were installed for engine protection. They are there by default across the rest of the Viper-powered line-up.

    trailer hitch for SRT

    I was one of the driver's of that car. There are no drawings or plans for the hitch on that SRT. One of the SRT mechanics fabricated that unit. He welded tapping plates into the rear frame rails for the attachments and slightly modified the rear fascia where the hitch came through the...

    High RPM knock detection and knock theory

    Quote:"I read an article recently mentioning Japanese tests that showed the higher the RPM the less probability for knock. Because it's all happening faster. I think it said that at 18,000rpm they could get away with something like 60 octane fuel." This is true. I have some experience with the...

    High RPM knock detection and knock theory

    Hearing is not an effective way to measure knock. Especially if you've been operating a dyno for many years. Yes, I say "Huh?" alot. The OEM's use cylinder pressure transducers, such as those made by Kistler. A passage is machined for insertion of the transducer from the outside of the head...

    Comp Coupe Cam Intake Centerline?

    The proper Comp Coupe cam centerline is 117. Plus or minus one degree won't make any difference.

    2005 SRT-10 Differences; Get a master list going...

    The con rods are a modification of the 5.7L Hemi rod which are lighter. That changes the crank balancing so the crank is lighter.

    The crank sensor is on the passenger side in the middle of the block like the early Vipers.

    SRT Cam swap with 508 (?) cam

    The early cam is the 708. The same cam for the SRT is the Comp Coupe cam. The early cams use one bolt to attach the cam sprocket and the SRT uses three.
