Yeah...... 11.5:1 CR sounds a bit steep especially with this installed;
custom stage 3 hot cam(holds intake valves open as long as possible),
After re-reading the discription I'm sure the brains/engine builder(s) behind the engine build up had a good reason for using the cam they did........I'd certainly be interested in learning more about their turbo-ing background!! It sticks in my mind that I recall from reading about turbo applications that you were certain to get max fill after the turbo spooled up even with a stock/mild cam as the engine was pressurized and not relying on vacuum to get the A/F mixture into the combustion chamber!????

If you talk to the owner again, ask him what a stage 3 Hot Cam is.

I have a 'stage 3' cam in my Baja 1000 bike. Its a custom grind that Barnum made. Its well past the HRC stage 2. In fact the valve stays open so long its hard to get it to idle smoothly... While not for everyone, the cam does have its merits...
If memory serves me, the Seedish guy ran a traditional turbo.
Speaking of turbos, the new generation of micro-turbos are not your fathers turbo units...turbo lag is largley a thing of the past. Turbo technology has advanced significantly in recent years.
For sure Ward, i am very curious to hear what you find...we can catch up in Baja in just a few weeks!

turbo lag is largley a thing of the past.
Variable vane technology has helped to reduce turbo lag.
There was no turbo lag in our 800 HP twin turbo Tatum black widow spyder dual sport buggy. It would stand up at practically any speed at the sand drags with the right tires installed, but it was a blast in the deserts or on the roads. I do miss it , but it was mostly a trailer queen at my house and at a few shows. I'm glad it's getting used now, but it doesn't have the bling that it used to and it's been crashed twice since I sold it. The only turbo things I have now are diesel trucks and a turbo T/A, but it would be nice to at least take a quick spin on a turbo BRP

I too am skeptical of the compression. Street legal, but does it run on pump gas? Yeah right. Although, if it makes an honest 92hp, then the compression had alot to do with it. The headwork made the most difference, however. And turbo engines DO like the right cam. Less overlap is usually better so you dont blow the fuel out the exhaust.
XPLRN - I have a turbo 10hp Briggs & Stratton project in the works. Goal is 50hp, expectaion is to blow the cylinder off the block. Crank trigger ignition and fuel injection a possibility.

They added a custom built single piece ring, and some other goodies, compression must of went from 9.?:1 to 12+:1 easy. I roll started it and it did 50+ in 3rd and was a 6 speed. Scared me, just too much power.
I sold it to a desert race guy and while practicing he shattered the rear hub when he gassed it doing 128mph in the desert, or at least that's what he told me.
Same dyno my KTm 525 makes 46, and my YZ450 makes 48. I'm much happier on those whimpy bikes, 70hp was just too much for me (at least in the dirt.) My knuckles turned white just on a sort ride. Not to mention kicking on it 4 hours one day til my girlfriend got tired of riding around the track waiting for my beast to start.
If you want a massive HP bike, start with E-start.

I don't remember everything, but the work order was 2-3 pages long, and the bill was $2,500.
The guy that did the work used to build dragsters before getting into bikes. He went crazy on this project.
Actually at first I just wanted it balanced cause the stock husky shock like crazy. Balancing was $1,500, so for just a little more I got a buch of stuff I really didn't want, but didn't know that til it was too late.
Trust me, 70hp is too much for most guys. This bike was flat out scary. (if you could start it)

I'm not even close to being able to afford some like this, but a boy can dream.
And also what would be involved in a rebuild on a bike like that? Just piston and rings?

"Atomizing" turbo? I'm anxious to know what in the world that is. I'm wondering if it has a turbulator installed in the intake and the owner just calls it a turbo.

How long would something like that last?
You realize that you're asking questions about posts made 12 years ago, right?
If someone responds, at least we'll find out if something like that can last 12 years.

Theoretically how long would one last between rebuilds us all im asking
