LOW hp stuff up to 1800hp? It will be interesting to see what you are building!

anyone have a dyno with dual water brakes?
anyone have anything with a very large water supply so we can do constant load testing for long time? minuites? hours? with out boiling the water?

Most Dyno's with a water brake wont hold that much hp,they will slip and give you false readings..

The only guy in the us that i know of that has a enursa Dyno that gives true hp and torque..

Mandolini Performance Dyno in villa park il,he is the designer and builder of the enursa dyno, his Dyno will hold 3000 + hp,he does alot of the nmca stuff,blown alchol engines.

630-782-0010 ask for fred..

I'm pretty sure the newer DTS will hold 2500 ft lbs.
as far as hours..... the boat!

Fred, the man in black....

Ours is rated to 2000 hp on the box:lolhit: but the manufacture said they have tested to 2500 hp with no issue:drink:
Mr. Fixx
I disagree to a point on the waterbrake not being accurate/slipping.I know you said most :drink:

Regular calibration and proper dyno room set up is crucial to the end result.
Crap in = Crap out, as with anything.
:coolcowboy:
As far as hours Shawn I would rather be out in the boat :evilb::boat:

Steve Morris in M.I. has a Stuska dual brake rated for 3000 HP.

Tyson, we have a new dyno that we use to run all the twin turbo and nitrous engines that are pushing over 2000 hp. Last fall we ran a hemi headed 900+ cu. in. all motor engine for the camaro that did 2250. And a twin turbo 632 on alcohol that did well over the 3000 mark. If I can help ya, send me a pm.

Hi Frank,
Where in LaGrange are you and where is the dyno?
I used to live by you. Just curious.
Father in-law ran ChassieCraft and VFN fiberglass with Frank and Victor in Addison.

:

we have the same dyno you are talking about and it will not hold anywhere close to 2000 hp.. they told us 2000 also but i can tell you it wont.

ours could not handle much till we made alot of modifications to it to make it not slip.



and slipping does not make it read wrong anyways just makes it so you cannot slow the engine down, it works on load against a cell not inertia which would read wrong if it sliped.

we are looking for someone with a dual stuka? or dual land and sea.

and it would help if it had 12 egt's

Tyson what about some of the turbine guys?
