    Oil Pan Mystery

    Yes. I have both the short dipstick and short tube. So something is holding extra capacity over a "stock" 8.5qt system. Be it the pan as I suspect or maybe the cooler.

    Oil Pan Mystery

    So do we think the "10qt" pan really doesn't add an extra quart and a half of oil but maybe .5qt and the other 1qt is attributable to the factory telling people to "overfill" their pan? The disptick is totally stock. Dean posted pics of the 2 different Gen 2 dipsticks and retainers and mine is...

    Oil Pan Mystery

    Thanks for the feedback Dan. Always appreciated from you. Exotic Engines is putting the kit together. As I understand it this is what they run on their 7krpm+ packages and I have spoken to a few former customers that run their gen 2 up to 7k rpm with this setup without issues. But I will be sure...

    Oil Pan Mystery

    In the pan. But another guy sent me pics of his 10qt measured the same way mine was measured and it was also 4in exactly. This was his pan:

    Oil Pan Mystery

    Got an interesting one for the viper brain trust. I have this pan off my '99 ACR. By all external indications, it is the short pan for the 8.5qt oil system (2 rib, early internal bosses, fastener holes bump out the side of the pan lip). I have the correct dipstick and tube for a '99...

    DIY 650+whp on e85/track ready budget fuel module

    The BAP module I used is the P2000GM by JMS. I used the GM version for two reasons. First It allows voltage ramping based on a 5 volt sensor. The viper TPS is a 5 volt sensor so I can run it off the TPS instead of RPM which would have been complex and laggy based on how these cars send the RPM...

    DIY 650+whp on e85/track ready budget fuel module

    My car with the 190lph stock Gen 2 pump and injectors made 465rwhp on Prefix's dyno. No fuel related issues whatsoever on track even during 30 minute sessions with low fuel. Regarding the BAP, it will be triggered by the throttle position sensor. It will start ramping from the factory 13.5V at...

    DIY 650+whp on e85/track ready budget fuel module

    FYI I've decided on using the 340lph racetronix pump plus a 17.5v boost a pump. This should turn the pump into about 520lph. Should give me some headroom on 93 pump gas to account for pumping losses. Probably gonna need about 400lph at the rails.

    Sourcing Obsolete Parts For Gen I and Gen II Vipers

    Call Don Scharf Auto. Should be able to find their number on google. Ask for the viper guy. They have a stash of viper stuff but don't advertise it.

    Looking for PDF service manuals

    Mind sharing the ‘99 with me? I have a ‘98 I can send back in return plus the body assembly manual and some other stuff.

    Don’t take my comments the wrong way. I absolutely appreciate your thoughts. Viper community needs more innovation. Keep the posts coming.

    DIY 650+whp on e85/track ready budget fuel module

    Meant 3 bar. Sorry. Not 2 bar. Drop 1 bar from factory pressure rating which is 4 bar.

    Short shifter options these days?

    Honestly you might like a Gen 4 knob (1" shorter shaft than Gen 2, colored stitching, otherwise identical) on the stock shifter. Jon B had some on his site this summer when I bought mine. If you do want a new shifter IPSCO is the way to go. I put the Gen 4 knob on an IPSCO with the 1" drop...

    DIY 650+whp on e85/track ready budget fuel module

    FYI for anyone looking at this in the future, Racetronix does make a 340lph jet that is E85 compatible. It is a special order. It is listed on the site but takes some digging to find and you have to call them to order anyways. Better off just calling. Removing the ridiculously small diameter...

    What really limits rev capability on these cars?

    Even with the added stroke they rev those out to 6500 rpm. And that’s with an internal stock style oil pump I believe, though its already on the Gen 4/5 revised oiling design and prefix installs better OPGs. The main issue with the factory Gen 2 oil pump is the pickup is too small for the...

    What really limits rev capability on these cars?

    Thanks Dean. I have seen his stuff. I don't think he's done much to the bottom end at all. I really think I'll be okay. Springing for the external oil pump like you recommended on messenger I think will make it live. I've talked to at least 2 guys running a very similar setup on a forged gen 2...

    What really limits rev capability on these cars?

    I'm really more interested in the engineering explanation behind why people thing the bottom end won't hold up at 7k rpm on the V10, when the 340 used similar design with 60s machining and metallurgy and its fine at 7k rpm. Maybe it's a function of v10 harmonics, idk. That's why I'm asking...

    DIY 650+whp on e85/track ready budget fuel module

    That’s pretty surprising to me. Are you boosted and on E85? I haven’t run the estimates for that but I have for 7k rpm NA motor on E85 and that would have been sufficient with appropriately sized injectors.

    DIY 650+whp on e85/track ready budget fuel module

    To answer your question about the racetronix pump and siphon, yes it does have that. If you go to the end of the 800hp fuel upgrade thread Dean’s posts are in there.

    What really limits rev capability on these cars?

    I've read every thread out there on this. So please don't tell me to search. My question is what limits the rev capability besides oiling on these cars? Specifically gen 2 but since I suspect the answer involves main bearings, and they are the same for all gens, it's sort of universal. Oiling...

    DIY 650+whp on e85/track ready budget fuel module

    Good solution for someone without a factory fuel bucket. I think Dean's method of adding the racetronix pump into the factory bucket is still the way to go for most guys with a stock bucket. I am taking this a step further by fabbing an aluminum adapter to sit where the original pressure...

    Low mileage cars and 'fixing' issue

    I agree. It's not a 60s and 70s muscle car. The first (oldest) crowd that became interested in restoring those was fanatical about bolt finish, factory paint marks etc. This stuff was pretty well documented in magazines at the time and the factories kept extensive records on production. This...

    New member looking for a gen2 gts

    You and others would do well to post the price range and mileage. If OP is not interested, I know several people on this board that would be.

    Why did ACRs never have special engines?

    IIRC, the viper ACR was competing against the ZR1. The T/A or T/A 2.0 would have been slotted against the Z06. I believe the C6/7 ZR1 needed a more powerful engine to increase the performance gap between this trim and the z06, which in turn needed more power to bump performance over the base...
