I finally broke into the 11's with my SRT-10

Re: I finally broke into the 11\'s with my SRT-10

Rick is 100% right on this. I'm tempted to power shift into second gear, but I won't until I've mastered quick shifting, and It seems like you get faster at it, and your timing improves. Another shift that is hard for me is third. When racing I don't go over to third in an angle like I do when normal driving, I actually go forward and at the middle point I go directly to the right, and then straight up. I'm pretty fast at this, but going cattycorner style is much faster and much riskier. My dad has power shifted his Viper before, and done very well at it, but he said for not to do it untill I've mastered my timing.

ps, their is a new T-56 upgrade gear kit that is built for all the power shifting you want. I can see this is a must. The gears are not straight cut completly, but close. Very streatable, slight gear noise, gear teeth are noticably thicker. There are many more things about it that are better. Thanks to the common use of the T-56 in other cars, this has been designed.

Skip, more details on the gear kit. Is it able to handle the same power load as what is stock? Would it work for those cars pushing near 1000 crank Horse Power?

Manny, no way you want to stay with the stock setup. If you ever decide to go with drag radials or ET streets, the stock unit would never hold up to that kind of HP. And if you have that kind of power, please take my word on this, and don't run a 3.55, a 3.33 is perfect on a car of this power. There are two great choices on diffs, the Quaffe, and the Detroit Tru Trac. They are very strong, and they are the torque biasing/sensing type. I know a lot of people will tell you the stock is doing great with there TT setup, but they must be sliding around on some slipery pavement, or they just don't get on it much. Pilots will give relief, but some day your going to be on some really good surface, and punch it, and it's over.

FWIW, I've run 11.6 @ 122 in my SRT (5-points & helmet), but it's no longer stock. I'll be going back now that it has a 3.55 rear gear to see about getting it into the 11.5s.

And Skip - while I respect your experience with these trannys, my '01 RT/10 has put over 40 dragstrip passes - on ET streets and DRs - and 1000s of street miles, at between 1000 and 1200 BHP and with a clutch which will hold all the power. No tranny problems whatsoever. Perhaps if I used those 28x14 drag slicks something would let go, but with the 11.5x26s it seems to be the energizer driveline...

So what's this I keep hearing about the SRT-10 drivelines not holding up as well as the Gen 2's. How different are they?

Re: I finally broke into the 11\'s with my SRT-10

Ben there was no mention of tranny's not holding up exept under frequent power or speed shifting, and believe me, that will kill the trany sooner or later. The SRT does have an improved main shaft design, but we were speaking of differential's not holding up under such power, especially with slicks on the car.

Manny the weak link in the driveline is the cross pin on 03's and is only slightly improved on 04's as they are breaking also. The Unitrax pin is a must in both cars. This pin is very strong, and has a few other good features to it.

1000 HP come on, thats a lot of power for anything in drive line to hold up to. But as I said the Pilot tires will not hook up enough to harm the car, maybe???

Re: I finally broke into the 11\'s with my SRT-10

Hey Skip - aahhh, the diff. Quite right, no disagreement at all. The stock unit isn't up to the task for hard launche- then again, neither is the stock clutch. A good set of 3.55 gears (for near-stock power levels) and associated hardware will fix the problem.

My car's now got the Unitrax cryo'd 3.55 gears, pin, etc. in the rear diff. Can't wait to get it back to the track.

Also - Pilot sports won't hook enough to hurt the diff, but they ARE much more prone to wheelhop, which will break the diff & half-shafts/CVs.

Re: I finally broke into the 11\'s with my SRT-10

Yes Ben, I've been plauged by some wheel chatter,(the precursor to wheel hop), and it can do much damage if given enough power. I just put in my 3.55's they really are working well with my 305/45/18 28.4 inch tall Nitto Drag Radials on 11 inch SSR wheels. "OH them", I forget to mention them on the board. If anyone is interested in how that project is going, speakup.

I just got booted from the Carlsbad track yesterday. They simply would not honor the new NHRA rules and said they do NOT apply to convertibles. I had the printout with me and it just pissed them off. Basically they told me, "If you run faster than 14.0, don't show back up with this car." I left and got a refund. Viper haters.

Re: I finally broke into the 11\'s with my SRT-10

Both Gen II & Gen III Vipers come stock with the Tremec T-56 tranny that has a torque input rating of 450 lbs.-ft. This was previously listed in the Gen II service manual but was conveniently left out of the Gen III manual since Dodge now exceeds this with its current 525 lbs.-ft. of crank torque in the SRT. I feel this is a conservative rating since the T-56 has held up extremely well for a number of years, in a variety of applications, where it has been exceeded by 2 to 1 margins.

Re: I finally broke into the 11\'s with my SRT-10

Rick,

True, as I beat (no really I do BEAT) the crap out of my car and it is putting around 800 rear wheel torque down. There has NEVER been a time where I took the car out where I didn't go wide open throttle for at least a bit -- you just can't help it -- it's like dating a ******* model and never once looking at her boobs in a full day ... just can't happen.

Manny,

When you find that ******* model, please send her my way!

COme to San Diego -- plenty of them, or girls better looking even.

Yellow Fever tells me San Diego girls can't compare (in terms of quantity) to Montreal, but I've never been.... yet. Jeff, when we going!?
