Dillon you're using an eagle crank and h beam rods right?

 

[Dillon Dollar]

Yes sir.

According to several sources the eagle crank is stronger than the Kellogg and they rate their rods at 1200. Even FRPP uses eagle in their short blocks now.

Anyone ever break a Kellogg? I know several over 700 rwhp on the stock crank no less.. Ran 1000 thru my Kellogg so far and going for more this time

I got ya. I was just trying to decide between the twin kit and the single kit with the deciding factor being whether or not my Manley h beams could hold 1000. If you're going for 1000 on h beams then fuck it, me too. Guess I'm gonna need another solenoid for my boost controller or is there a way to do it with 1 solenoid?

Sub'd! Can't wait for this!

When you see a manufacture (at least a reputable one) post numbers they are normally RPM dependent. Those tests are done at sustained RPM also which is not you unless you are RickyBobby.

IIRC, my Manley I-beams are only techincally rated to like 800 but that was at 8000 rpm under sustained conditions. Hell, I ran my manley H-beams higher than that and they are only rated to like 700 @7000 rpm but don't quote me on that.

RPM is a huge factor on the rods. The majority of the strenth/weakness is in the bolt

Well I plan to spin to7k but I have the arp2000 bolts.

ARE THESE DONE YET?????? zzZZZZZZzzzzzzzzz

If no one has broken a stock 3v cast steel crank I would hope no one as broken a forged one.

Termi's run 1000rwhp+ on stock manley h beams with arp2000 bolts all day long. Granted they are usually a tad lower compression and don't rev as high always.

Kellog 3.8" crank..not worried about that.
More concerned about the rear end, as I feel that's a possible weak point now (gt500 8.8 take-off with stock axles).

Your several sources??? A Chinese Eagle crank stronger that a Kellogg?

 

[Bobby]

You can do it with 1 solonoid. I do it that way

 

[Bobby]

Also i have a 100% stock rear end all i have done is my axel tubes welded

..mine are not welded...yet. that's what worries me! That'll get taken care of soon

the eagle is a 4340 steel, kelloggs is not so yes the eagle should be stronger but much heavier also. me personally, i had both and after mic'ing the crank and based on appearance straight from eagle, I decided against using it and went with the kellogg as I've not seen a breakage in either, only rod failures far and few between but i also run oliver bilet rods with wsb bolts. i did a thread with a side by side

All of this talk about cranks is irrelevant, as the Kellogg is no longer available. I ordered one from Lunati a couple of weeks ago only to have them call me back and cancel the order. Everyone I have spoken to is now using some version of the Chinese crank. MMR claims to have a couple.of standard stroke Kelloggs but at almost twice the normal price.

 

[go302]

What material is the Kellogg made of? Pretty sure it's 4340
