Re: MORE FRIGGEN HORSE POWER! SPAM WARNING!
 
Well as of right now the engine is out, apart, and at the machine shop.
It is being bored .030 over and the heads are getting resurfaced etc...
so that should increase compression. It is getting ported as well and
since we are replacing crankshafts camshafts and pistons I am going
with the 4.2l budget stroker which should yeild about 260 HP

Cool, it should rock.

I have a 4.0 with 310K km on it in our Cherokee and a spare 4.2L sitting
in my garage.... The stroker idea is enticing.

Re: MORE FRIGGEN HORSE POWER! SPAM WARNING!
 
Hi Scooter,
Welcome to RAMJW. Not that these discussions can't happen here, but
you really should go check out the yahoo Strokers group, as that is
where most of the technical discussions on these build-ups occurs. There
is even one member is CNC machining silvolite pistons to reduce the CR
of the stroker to a reasonable level. Are you going to deck the block?
It is recommended to restore some level of quench compliance, although
the benefit of this is still being debated. 4.21 sounds odd? are you
going the stroker route, or simply an overbore?

Re: MORE FRIGGEN HORSE POWER!
 
Does it need to get up to 3500 rpm to top the torque or does it pick up
early with a flat top to the curve? I was under the impression the
stroker has a low rpm pull like the 4.2L has. They de-stroked the
engine when they made the 4.0.

That is Dino's site. He is the guru on the yahoo list. BTW, the CNC
dished Silvolites will get your CR down to low 9s so you can run pump
regular without ping. Otherwise plan on premium.

You go first Bill....
You go out and buy a new KJ and hook it up, invest the $30k and then put
your money where your mouth is.
If YOURS can take it, then I'll do it.

Re: MORE FRIGGEN HORSE POWER!
 
If you check out the link to that site there is a graph that shows the
TQ curve as the 4.6L stroker (the one I will actually end up with in as
they are boring it :) reaches 2000 rpm it is over 300 lbft of TQ and
at 2500 there is about 320 and only bumps a bit higher to like 330 at
3500-4500 then drops to 260 at about 5100 and then EXPLODES LOL :)

If you check out the link to that site there is a graph that shows the
TQ curve as the 4.6L stroker (the one I will actually end up with in as
they are boring it :) reaches 2000 rpm it is over 300 lbft of TQ and
at 2500 there is about 320 and only bumps a bit higher to like 330 at
3500-4500 then drops to 260 at about 5100 and then EXPLODES LOL :)

From what I've seen (insane inline JP magazine, they dyno a Golan
stroker in an XJ) the torque curve is more of a "line" damn near dead
flat all the way to valve float RPM's

It's got something like 100lb ft more at 1800.

I'm convinced the 4.0 explodes at anything above 3500 :-)
