When is a stroker to overkill?????

[coldforge]

ok, I'm thinking of making a stroker engine as i see it everyone is staying around 4.7. Is 4.8,4.9 to much of a overkill for a cherokee? I'm thinking it's becuase of weight to power ratio. I want to make a 4.9 because a 4.7 is only what 40 more Hp.

I don't think it would be over kill.. but it might get expensive depending how you intend to get the .1-.2L over 4.7.

 

[coldforge]

yeah, but 40 HP gain. Is that really alot? Plus i do understand all the other stuff you have to do to make a 4.9 run. I dont i guess its one of those things "if you don't have it, you dont know"

 

[Talyn]

Most strokers will be around an 80 hp gain. 270 hp vs stock 190 hp.

 

[coldforge]

well i see you have a 4.6. hows that working out for you? what do you do with your jeep? becuase mine is a daily driver, highways, and MUD!!!!! lol

 

[coldforge]

Also i want to build it myself because i want to CYRO freeze the whole engine

 

[Talyn]

I'm having some issues on the cam on mine. Mine is daily driver, some trails, nothing too hardcore. Its only 3.5" w/ 31s. When it was running it drove great.

Can you do the cryo yourself?

don't do it. The higher you go, the thinner the cylinder walls and the hotter it will run. go 4.6 or 4.7. Beyond that, just get a LS1.

only a 40 hp gain? where did you get that at?

I'm sure I am at least 75 horses up with a budget 4.6 - it will spin the 37's all day long.

I'm putting together a built 4.7 I am expecting to see closer to 285-300 out of.

The power comes from your cam, head, intake, etc. How much you bore it out is almost irrelivant.

 

[coldforge]

Whats your compression rate going to be?

 

[coldforge]

No, there is a shop up here in washington state near tacoma that does it. The only thing that sucks is you have to have the engine broken down. Also thinking about doing my axles to just not the shafts

There is a place in Mooresville,NC that does it if you still have your engine apart

Mine is 9.5:1 static and 8.3:1 dynamic.

Did you use a kit? If so who? or did you buy the engine made

 

[Talyn]

Not a kit, not pre assembled. I purchased the parts my self and had a local machine shop do the machining. http://www.naxja.org/forum/showthread.php?t=977237

So did you not like the titan?

 

[coldforge]

WOW!!! you put everything in that engine that i wanted to do

 

[Talyn]

No, the Titan was a POS.

 

[coldforge]

thank god :banghead:you told me i was going to buy a 4.9, But i want to cryo freeze it. Why didnt you do your block? If i was going to use a kit what do you think would be the best? hesco bakes thier pistions but im going to cryo them. I want this 4.6 or 4.7 or what ever :yap: to last

 

[Talyn]

Cryoing everything was too expensive and I thought it unnecessary. I did the rods and bearing.
Hesco's pistons are made by Diamond, don't know about the baking. Hesco's kit is good but expensive. 505 performance has a decent forged kit, but pricey as well. I don't know off hand other companies that offer kitrs at this time. Also, Titan goes by several other names on ebay like hammer hear, oldyeller, and something else. Basically if it is in Ocala, Fl its Titan.
