In the cases below none of it is accurate.

Correct, Guy did tell me that a failure had happened at the snout of the crank, due to what he believes to be caused from a bad tune/ injector ballence.

I personally think that it would have been OK had it been internally ballenced, but that's exspensive, and not very practicle for street use, only full out racing!!

What I said was I have seen numerous factory cranks fail between the number two main and the first rod throw, upon further investigation we found the modifed injectors were way out of balance from cylinder to cylinder. Thankfully, they were not injectors that we had supplied. It did however cause us to change the way we test injectors for our customers. All our injectors are now flow tested as complete units at 160 MPA. Most shops only flow the tips at about 30 MPA at best and never test the bodies.

The internally balanced vs externally balanced debate will rage on forever. Most high rpm racing engines are internally balanced, this focuses all of the balance weight inside the front and rear mains. I don't feel it is a big issue (internal vs external) in a 6,000 rpm engine.

As we increase power further and further away from stock levels the natural harmonics of the engine also change requiring a balancer capable of absorbing and negating those harmonics. Hence the reason for the SoCal Super Damper.

Diesel Power spends alot of time on the phone getting advice from alot of people and seems to get his facts mixed up sometimes. What is really amusing is when he states as fact, something in a conversation I told him the week before. I know I have over 200 hours invested in phone conversations with him about engine design and building his engine for him and now he has decided to do it himself.

The first stroker cranks are made by scat for guy's 7.1 liter

This statement couldn't be further from the truth. :rofl:

Guy's, I don't make the cranks in house. In the beginning I had proto-types made by 4 major crank manufacturers and asked for bids in 25 piece runs. Crower was one of the companies I solicited a bid from, so I guess that is what that sales guy was talking about.

After inspecting the protoypes I then settled upon my primary and secondary vendors. I stand behind these cranks as if I made them in house so you have nothing to worry about there. Rest assured the vendors I use are very very good at what they do.

You may speculate all you want but I will not reveal my vendors, for obvious reasons. Sorry. :(

Crower makes one of the top cranks before you get into the HIGH HIGH dollar crankshafts. I've never ran the D-max version, but I've got three SBC cranks in the garage. I've never had an issue with quality or performance.

Just got off the phone with Crower. They say around $3000 for the crank and about 4mos wait time. He did say that Guy ordered 25 cranks, and it would be best to go through him. He also said that they make the 7.1 crank for Guy FWIW...

Thats prob racers net,Id try and get J or EB.I know on a SBC 4340 theres only around $125-150 diff in J and WD.If he bought 25 he would be would have bought in lower than master WD.But the set up might of been bad$$$$

But its like TA performance and there cranks and blocks, they could sell them cheaper than ya could get it anywhere else.I would think The foundry probably wants a 25+pc min order.

The way I read it, Guy says no 7.1 cranks have broke? Interesting...:rolleyes:

Exactly!!!

Since Guy wants to beat around the bush and make it "look like" he has had no failures and degrade me and make it look like im the ass here i'll tell you what GUY told me Himself.

First off, Guy you Might have spent at most 20 hours on the phone with me( i have phone records i'll post up if you like!!) So dont try and make chicken soup out of chicken shit!

Second, Guy im building a 100K project with a 1/4 of that money and funding---Thats why you are not buliding my engine, and i told you this last week and you were ok and understanding of this fact. Yet i have told you that i would use your ported heads and other various engine parts because of the help you have been to me, as money allowed!

Yet your post seems to me like you have a heartack about this, Well you yourself told me that the money i had would not be enough for you to build this engine, so with limited funds, i told you what i had to do, save money and build my own engine! If you did'nt want me to do it myself you should have bit the bullet and built an engine for what i could afford, but you did not and this IS what has to happen. you shouldent feel jaded about this at all. Thats just the way it is!

Now i feel like you dont even deserve for me to support you because of the way your worded you last post, making me look like a ass/ and or lier, but the truth is that YOU told me yourself that you HAVE HAD crank failures, but yet you come on here and lie to the diesel world about it at my exspence?

Thats not a good way to do bussines Guy!

My advise to you would be to Think before you post and appoligise to those you may have done wrong to, and most of all tell the truth about your cranks! Because really you have nothing to lose because you personally did not make the cranks, so it's not your fault the crank broke, but it is youre fault that you sidestepped the truth when asked.

If you want anything to do with me or any of my projects, and any of the bussines that will come from your products being on my truck then you need to make it right with me and the diesel community. You know my number!

I have heard that Wes Kusilek has broken more than one stroker crank. a) is or was he running SoCal stroker cranks? b) Is this information about breaking two of them true or false?

Just wondering.

Privately, I was told that it appears I'm "protecting" Guy Tripp.

Let me explain where I'm coming from:

Problems we had with Casper were always made public. And they were used for marketing purposes for aszholes. If you read the right threads, I've blown up 5 engines, blow up every truck I tune, my truck weighs 5000lb, the trans has blown up several times, I cheat at competition events, blah, blah, blah.

I've been banned from 2 sites for doing nothing but defending against such crap.

If this was DP, Guy would be banned because he replied to an attack. I'm not going to ban Guy, or Wade.

Wade is not a Dmax guy. He has done nothing for the Duramax community, and now he sells Duramax parts. If it looks like I side with Duramax folk over some Dodge guy hunting free parts, too bad. That's me.

Yes, I'm running the Guy 7.1 kit in our Bonneville effort. Yes, I buy parts from Guy. Whatever Guy told me in private about 7.1 kits was private. I just tuned another 7.1 truck and apparently it's a freaking animal.

Guy has done great things for the Duramax community, and he deserves at least a little respect for his efforts.

Im not passing judgment or anything, I just would like to know. We never get the full story with anything anymore.

You never did. Perhaps the "illusion" of the full story, but never the real deal.

There is a huge stink over rods right now, and trust me, you've only heard a fraction of it.

But I do not discuss failures except my own trucks, or trucks I'm involved with. It's up to the owners or folk involved with a truck to decide how much info they provide.

But it seems like many folk demand that others provide everything they know publically for free, yet seldom walk that line themselves.

After seing how much crap can happen when you have a high profile truck blow up, I really don't blame folk if they decide not make it public.

X2 Pat, I and others understand that, some would like to hear the whole story though. from Guy himself. If these cranks really were breaking (which I still havent seen evidence yet). Its kinda funny though, with the recent events and all....

per your second post:
Dont get the feeling I'm against Guy. These post never come out right. all the secret stuff only makes things worse IMO. People are led to conclusions.

and you are correct, I dont know the whole story with Nick ;)
