Clutch test - new info

[yamadoo]

Mark, I have a really good setup right now....but know I can get much more out of the viper. The winter we had was a great one, but it was late in the season when I talked to Bill (Stingray) and tried what we talked about. I was really trying to get the stock weights to work and I was able to do a good job, but the stock weights and belt setup were not working and I wasn't gaining any ground. I did very well racing.....but now with the different weight setup, I didn't just inch forward....I leaped forward increasing belt life, fuel mileage, top speed and increased the fun factor

Can't wait till the snow falls again!

WOW belt life, mileage , fun factor and top speed. I know its july but let it SNOW!!!!!!!!!!!! I cant wait.

Were are the recent asphault results? What forum and thread?

Certainly not going to be revving it to 10k..but the engine should be allowed to atleast get in the 9200 range since the sweet spot is 9000

I am just saying what this tuner was telling me---he clutchs his turbo's to 8500RPM for safety. He claims he is only leaving 2-3 horse on the table vs 8900 rpm's. I specifically asked him why he wasn't clutching to 8800-9000 and this was his answer.
What has everyone else seen for a power curve on the Turbo aplication? I will be installing a turbo this fall and want it to be clutched correctly yet safe. I usuall do my own clutching but was going to go with the supplier's advice on this set up as this is my first turbo sled. My current stock set up is 8800-9000 with no problems. Stock belt with no dust or binding.

I can understand their reasoning for not clutching too high, possibly they don't want to rev too high and cause any risk of detonation..there are tuners out there that are close to having ecu reflashes, I personally see the most potential there. They will be able to cure the starting issues with proper programming, increase rev limiter for certain applications and also for the turbo sleds be able to detune the timing to allow for slightly more boost with less chance of detonation. As far as clutching on a turbo viper it's all going to depend on the sled, really hard to say it's gotta be one way or another without testing different setups and different rpm ranges. The stock viper is proof of that, on the dyno my sleds peak hp was between 8600-8700..with the sled clutched in that range it was a turd in comparison to how it is now running 9000 rpm. You're prolly on the right track with going with a setup made for the turbo. For myself I'll be able to work with my dealer who is setup with a high end radar gun that gives you speeds and times for every distance out to 1/4 mile. Works great that way because you can specifically fine tune your exact sled in your exact location rather than buying a kit from someone who does all their testing half way across the country in what is probably a very different setting. I'm just a flat lander who is mainly concerned about drag racing so my setup will be much different than the strict trail rider with a turbo..a lot of different factors but I'm sure there's guys out there that can get u darn close on a setup
