Rappy97 well you and me both.

ALL DIESEL MOTORS MUST HAVE ATLEAST 17:1 to ignite most pickups are around 19-21:1 compression with5 psi boost added on to that. You can easily push a diesel past20 psi but it is a short life motor and if a diesel turbo oil seal goes out while running that motor will run a way and say good by to that one

Just an fyi. I ran a awd talon tsi with 19 psi of boost all day long as my daly driver.. granted it had 8:1 compression, had 345whp.

Most of the stock diesel trucks run more then 20 psi of boost and can run more because of the fuel they use and how heavy they are built.

I used to pull farm stock tractors with a friend and we seen more then 50 psi of boost.

 

[97warrior350]

Yeah but 50psi is heck on the boots.

 

[jasonp]

hey man im trying to get back on topic hah.

Callin Bones out... How long have you had you +4 crank? Strokers just scare me for reliability. If i was to strictly race mine then you better believe i'd be a 446.

I understand that the Hotrod cranks and stroker pistons are getting hard to find?

The only thing you have to be worried about when you stroke is not to rev it to 9500 rpm otherwise you will be putting in lower rod crank bearings.

That motor needed that boost to ignite the diesel

Let r buck.

 

[jasonp]

That motor needed that boost to ignite the diesel

maybe if you are talking about a pos detroit diesel otherwise no.

Oh crap this thread just got ran over by the kids

 

[rappy'97]

WHAT? I didn't do it!

 

[jasonp]

WHAT? I didn't do it!

You have a.d.d. :tup:

 

[rappy'97]

Lol

Rappy all **** seems to center around you

Is that about the red line for a stock stroke warrior? Do you have any experience with the Dyntech programmable cdi's? I have one, just wondering if the rev lim can be changed higher or lower?

 

[rappy'97]

Woooot. Atleast this is in the off topic eh?

 

[87warrior917]

Woooot. Atleast this is in the off topic eh?

Very true.

 

[JonS]

Warriors, diesels, or turbos. Which did I come here to see?

Yes I have a Dyna CDI. I have played around with timing and rev limit. You can change the limiter to what ever you want. I don't think they sell this box anymore.

I find that adding more timing just off idle around 1500-2500 rpm gives the warrior a little more throttle response and snap. Then if you look at the stock timing curve it peaks at 33 degrees at 4500 rpm and drops down to around 28 at 9000 rpm. It is better if you can hold or advance timing as you go up in rpm. It's a good way for the factory to control rpm.

Maxium piston speed is around 4000-4500 fps depending on how lucky you feel. I find if I spin the engine any faster then 9500 rpm I burn out the pickup coils on my stators.. that is about 4020 fps of piston speed. You really don't make any power up there so no point to rev it that hard anyway.

Here is a cool link.

i have had it a little over 2 years now i dont get to ride it that much tho

Cool link! Ok my next question is how do i change the rev lim? Maybe mines diff then yours but i have 4 settings. 1-stock timing 2-lil more timing 3- more timing more mid range a lil top end 4- mostly top end. pulls real nice it the high rpms.

I mean is there some kind of link to hook up to the computer and tune it?

On mine there the plug that has the 4 diff pin setting, theres 4 female connectors that connects to nothing, and there a big black connector with a plug end on it... i have the papers for it some where, just gotta find them.

Diesel has ignited down to about 14:1, but is very inefficient at that. I know of many diesels running well over 20 psi and the only main mod to handle that is studs. Many of the ones I know are 7.3 and 6.0's. As for a turbo seal blowing causing a run away motor that is old school IDI's. Unless someones doing stupid **** on newer motors. The amount of oil needed to rev an engine high enough to make it run away would be alot!! Which means the leak would have to be MASSIVE!
