OKAY... now you got me interested in your setup....

I've been wanting more and more out of my DS but can't run race gas or anything too high of an octane... why? you ask? Well, I run my DS in Mexico quite often... and the only octane is about 86 or so max.

You're running your KMS with stock internals which is KILLER!!! I wanna do the same, but was always a tad scared of how it would run.... now that you're doing it... I wanna know every detail. Everything down to how long it'll take me to install, tune, and be ready for my next ride to cost of the total install.

Do you mind PM'ing me with some more info?? Or better yet, how about a phone call sometime during the week in the evening? Seriously, I've been wanting more out of my DS, but don't want to sacrifice reliability due to it being 200miles out in the middle of nowhere at times.

Help me out Senior!!! Come on!! HELP!!!! I got the Turbo itch now!!!

Also... if it makes 60 horses... that's 60 RWHP right??
And if so, what's a completely stock DS make for RWHP??

Thanks brutha!

 

completely stock ds on the KMS dyno makes low 30's - with 7lbs of boost I'd be surprised to hear that he was running regular pump gas as opposed to race gas. So what was it?

 

So with that....

The DS makes almost double the HP with a KMS turbo on low boost?!
(or low enough boost it doesn't work the gaskets, seals, etc...)

Maybe I could run "octane boost" [img]i/expressions/face-icon-small-smile.gif[/img]

 

Ok , I just got off the phone with Kelly @KMS they ran 110 race gas and there where a bunch of quads that overheated due to the punishing course they where running( apparently the cinders really work engines hard- haven't been there but that confirms what I heard from other sources ) so the results of a hot engine arn't too surprising- the good news being the fact that the system performed flawlessly irregardless of the brutality of the race course.

The combination of Turbo selection and placement is what creates the phenomina of amazing power that is produced even under relatively low boost setting. Under normal conditions one is told that to double the output of a given displacement that one needs to double the atmospheric pressure ( appox 16psi or 1 bar) however this is being turned on it's head @ KMS and even the engineers at Garrett Turbos are scratching their heads and can't explain why such low boost levels are making so much power. So our desert racing friend went from making 35hp/35ftlbs of torque with a piped EFI DS to making about 60hp with just 7lbs of boost is really incredible but IS whats happening. In the real world it must be doubling the amount of oxygen molecules going into each charge but the boost level is still relatively lower than you'd expect.
The boost can be adjusted from 0- whatever by the turn of a boost controller so if you start the race running 110 oct @ 7-8 psi you would need to turn it down to 1-2 psi if you found yourself running 86 octane- the last thing you'd want to do is damage your engine running too low octane. I've played with octane boosters but I've never actually found one that was scientifically proven to raise octane by more than a point or so.

 

so you can run a turbo with low octane, sounds like somethin for me, too bad its so expensive [img]i/expressions/face-icon-small-sad.gif[/img], i wonder how a turbo would do for trail riding, haha

 

AHA....

EFI!
I think I missed that part.

Now we're into a large and deep pocket.
In my house... that's more than one deep pocket. [img]i/expressions/face-icon-small-wink.gif[/img]

Adjusting the turbo... nice, something that helps a bunch.
I can see it now...
GLAMIS - 7lbs on 110oct.
Mexico - 0lbs on 86oct.

Am I sounding like this could happen as such??
Or am I dreaming??

 

you got it!
