I gona re phraise my questions now.I have several buddies over here that wants to put turbos on theyr M sleds.
What is the cost and what do I need to send to you to get 285bhp@8,5psi boost@4300ft?And do I get a HP garantee if I take it to Dynotech for testing?
The other people/companys that I have been in contact with says thay need 16-17 psi @4300 ft to get that hp number or 12psi at sea level to get 280bhp.
Why is everybody so stuck on dyno numbers? We dont ride dynos, maybe we should all carry our dyno sheets to the races and shootouts then we wouldnt even have to get out of the truck to see whos the winner. Just think of it, no more injuries, broken parts, tuning, snow conditions, and excuses, its all there in black and white.
Well, I agree with you and by far the best info comes from races and comparing with your buddies.
But people want to know what they buy, and a dyno test when done correctly is a way to quantify the value of your purchase.
Now on dyno runs I like to see a video with audio!!!! Tells a lot more.
Look at these to runs and make up your mind. One is a 800 IQ and the other is a T-Cat so not comparable as such, but notice how much time they use to get peak power. Look at the needle in the left window (torque). Left is rpm and Hp reads in the small digital window in the upper middle.

Enjoy!
Why not take it to Dyno tech's dyno? An independent company...
Norway.
On the 800 he made a nice QUICK 4 second drag race type test.
On the t cat,, it was NO TEST, just flash's he never loads the engine and sweeps down or up. just flashes it..
that test should be pulled off you tube, I would be shamed to show that poor test to anyone..
any data from that type of missuse of a waterbrake is pointless.
Check my stats on dynotesting,, Snow Goer, 2004 truth in dynoing article done with Olav and myself. Edited by Craig Vorhees..
I worked on the Dynomite project at Land and Sea from 1992-95.
thats how we learn to operate them ,, practice.
he did a great job on the 800 twin.

The reason for that Cat to build so fast HP is more that he varms up the pipes realy vell before the pull.....Dont agree, he holds the T-Cat steady. It's just darn quick to build power. Did you see the text in the intro? Those are a mix of wins from both sno-x and prostock. Unless you think those warm-ups were part of the test? See how he uses the mouse on the computer to start recording? Then the real power is applied. Watch between 1:55 into the movie and past 2:01. Isn't that motor holding the peak power?
I know the language makes it difficult, but try searching for PF racing/Peter Forlund and use google translator. He's put more than a decent share of riders in 1st place...

Regardless,

This are the acual numbers.because its corrected to sea level.
Just like all corrected printed dyno outputs..
When testing at altitude,, observed Uncorrected numbers are what IS REALLY Happening..Those fiqures would be much lower..
We clutch to the engine and its real operating comditions,, Not the damn dyno room Or any damn correction ****in factor.
