Joyner trooper rev limiter

[Tobie1987]

I was wondering if anybody has done anything to change there rev limiter.. mine is 6,000 rpms now.. I'd like to get it set at aleast 7,000 rpms to maybe 8,000 rpms..to help my turbo get spooled up alittle more..

Amazon sells a "magnum rev limiter programmer " for the trooper.. it's supposed to advance timing too..does know anything about it ..?? Does it work..??

I've tried to install one before ,STAY FAR AWAY !

biggest piece of **** I've ever seen !you need to disassemble your ecu and remove the crystal 1 wrong move and your buying a new computer and once I had working it didn't do more than 100 rpm difference

Ok.. is there any other way..??? Any of the msd stuff work..??

[dwaynebradley377]

I've installed a msd coil just better spark ,was told not to try to go past 6300 rpm or else might blow up

[Tobie1987]

what  msd coil do you have..??

[Tobie1987]

Did it help any..??

The Rev limiter is there to save engine.This engine dose not produce any hp gains or torque at a higher rpm.And with the turbo charger it will come apart.Turbo kits just don't work on these engines.That is why super charging is the only way to go.If you want more top end go with bigger tires.Hope this helps.

Thanks Rich

Thats the one ,had to modify the connector slightly so would plug in .

Silver bullet is correct about rpm limiter  and  for more speed go with bigger tires but not to aggressive of tread hard on belt if you go bigger than 28" I've tried the 30"zillas and went back to 27 bighorn 2.0

[Tobie1987]

Thinking about goin with a smaller turbo to spool faster on the low end.. the t3 turbo I have is too big and it doesn't get spool until the the high end.. I need more low end.. bigger tires would gear it up ..I'm running 26s now.. i hill climb and rock most of the the time..

If you go smaller you will lose top end.Dose that matter to you if so than you have a problem.

Mine doesn't go into boost until around 4500 rpms and the rev limiter is at 6000..I need it to spool at like 2000 to 2500  rpms I can't afford a supercharger

changing out your turbo would be where I would start,have found contrary to Silverbullets experience that a turbo can and does work very well on the trooper.besides poor plumbing,and poor fuel control...the most common mistake is too large a turbo   just my 3 cents...Hardy

I run a turbo with 30" mud tires on my T2, top speed is around 55 which I seldom get to.  I still have plenty of power in deep snow or mud which is where most of my riding is.  I replaced the rad with a much larger four core one which keeps the heat down.

You will blow up your engine at any whear near those RPM.

I went with a smaller turbo and it's a lot better only hit the rev limiter now if I want to.. lol

[hfrick]

sounds like you win...  congratulations   Hardy

I have the cams from Silver Bullet. I really like them a good upgrade.

We have sold them for years.They work out great more low end torque wider torque range.We have them up graded a 1 year ago.Now better response in the middle  1,900 and up.We have one for forced induction.

[dwaynebradley377]

will the forced induction still work fine if the turbo was ever taken off?

I just ordered my rod and main bearings from your store do you have cams in store?

meant in stock

We had them custom made for non forced induction.And forced induction.So i would say no.I don't think it would be as good for a non forced induction engine.

Thanks

No our cores are out now and it will be a little while before we get them out.

Thanks

[dwaynebradley377]

what would timeframe and price be if I sent you my cams to grind?

The torque curve and the horsepower curve are different.  But one unique thing about these curves is they meet when the engine RPM is 5252. It's an engineering thing that you can research.  That is where the engine at its highest efficiency but not necessarily where you'd want the engine to operate all the time.  So spinning the engine faster results in less torque and horsepower unless you add a super/turbo charger.  I would be concerned with spinning these engines much faster than about 6000 RPMs for a long time that the engine would stay together.
