I have Peter Blach's former Viper here and the new owner wants a slightly better ride quality. He is certainly not into racing as much as just cruising. I can confirm that the ride quality is absolutely horrible. I do not think that I have ever ridden in a more uncomfortable car ride-wise. Currently the car has KWs on it as Peter told me. Are there any other options out there that would stop this car from riding like a truck?
Larry, try some Aldan's with softer spring rates. You can order them however you want and they are adjustable. I bought the Aldan's for my viper, but I have yet to install them.

Larry,
I have a set of O.E. springs and would love to part with them. By the way, the shocks are adjustable to an extent.
If you are interested in them pm me, I am in the Chicago area. A friend of Wayland and the other boys.
It made 890 at base boost. 1005 at 13.5 psi. About the same as it did in TX. I did not go any higher because we were out of race gas although I probably had some room to go......... The new owner is not that concerned about higher boost numbers as he is with drivability so I spent most of the tuning time on that. The car runs perfectly now!
I will let the new owner know about the offers to swap for stock springs/struts. Thanks guys.
What are the spring rates front and rear? Are the sway bars changed?
stock suspension will be numb and slow to react for those power levels on the street. It will also roll over on itself and pretty much suck.
Putting your customer in a higher quality shock/spring is your answer. JRZ, MOTON, PENSKE. Spring rates depend upon your customers exact use.
Doing a complete hands on/laser alignment and setting the compression/rebound/ride height/rake/corner weights for precision control on the street/track is also key.
Or:
You can take it to an alignment rack at the local tire shop with some bargain basement shocks with crud springs and you'll get the wagon wheel ride with no control
Yup right on with what the car made in TX, thanks Lar!
As for suspension, when the car left here it had Hennessey/KW's on it. I honestly loved the ride and didn't think it was bad at all. The car was freshly aligned, had adjusted ride height, corner weighted and drove like a charm IMO. It may just be that it's a Viper...???
Lar:
Stock - sucks
Aldan - sucks, unless you like the car bouncing up and down and left and right everytime you hit a bump
Penske/Moton - pretty much your only option

On one of your past post you claimed over 1200 rwhp on 15 psi. So the new owner only making 1000 rwhp at almost 14 psi Those #s dont look to close to me unless you picked up over 200 rwhp on 1.5 psi.
Hey good friend, thanks for the post! I was quoting numbers from my tuner so it could have been 15.63738229199 psi or maybe it was 15.329198373 psi. In addition, as you know, two dynos, two different cities (one north one south), two different tuners with a completely different tune (Nenni vs. SP), and two different types of dynos (one is mustang and one is dynojet). Lar (SP) was there when my car made the power (as were 50+ others - including the whole VW team). I do truly appreciate your concern though!

You said they were right on anyway your dyno #s?? like that 8.70 @ 174. What happened to that video? Maybe you got confused and actually ran a 8.70 1/8 mile et with a 1.74 60 ft time. I don't expect you to know how to read a time slip anyway since you are so against drag racing after running that whopping 12.0 1/4 et
We have a Mustang Dyno, not a dynojet...... Everyone complains that it reads low. The car is definitely making more HP than when it arrived. On the first few pulls, it pegged the a/f meter at 10.0 - 1. It picked up quite a bit when I leaned it out to 11.5-1. The timing numbers are roughly where Justin had them, I just smoothed out the map. From what Peter told me that the car made at lower boost levels, the car is dead on ..... based on other comparisons to dynojets. I was also in TX when Peter dynoed his car and saw the numbers.
I have learned over the years that you cannot compare dyno numbers from one dyno to another. Just use the dyno as a tuning tool. People that boast about dyno numbers have other more serious issues On the track, trap speeds are a better measure of actual rear wheel HP!
For example most 6 spd cars will dyno lower on my dyno than on a dyno jet. However my supra with the high stall converter will actually dyno higher on my dyno because the rollers on a Mustang dyno are so much heavier than a dynojet.... they load the converter better. My car dynoed 980 in TX on a dynojet while it dynos 1300 on my dyno. The car traps 170 and weighs 3550 which idicates that 1300 rwhp is correct. Go figure !!
Also we added four mufflers to quiet it down...... it is still obnoxiously loud!
Back to the suspension.... the new owner also has a new Z06 and wants the viper to ride similarly..... any suggestions?
Thanks
Lar

sell it to me for $10 and buy another z06. Hell, Ill even take it for $20!
I was there during the tuning and that car is loud as hell. I hope you get the suspension figured out and I hope he takes that car out and does what its supposed to be doing... racing!
Id like to see that car on 10psi vs the stock motord CPE TT car on the same boost from a roll on.... I wonder if the owner would be down?

Yea thats what im talking about..... what was Peters mph on those two 12.0 runs?
Lar.... Go with the Penskes. They DONT get any better then that
Kevin - aren't you the one that was too scared to show up? "The car just isn't running right..." "The suspension isn't dialed in..." I'm not getting into it w/ Garth b/c he's my friend but the fact remains that you bitched out. My car wasn't even done at the time of the meet, it had ZERO road miles on it, had NEVER been driven, and only had about 25 dyno pulls on the motor. We decided in good spirit and as good sports to go ahead and make a few pulls. The first run was simply a shakedown run to make sure all the hoses were tight and that there were no leaks. The second run the pinion broke. You can poke fun all you want but the fact remains that you bitched out and we brought the car out in spirit and in fun. How's that????
