Build costs

[Relentlesscummins]

also depends on # of passes you expect it to hold, i got 812 on stock LB7 rods.............................................................. , but only lasted 2 dyno runs and 1 - 1/4 mile pass :spit:

Thanks:thumb:

Was that with twins on fuel ?

That was a stock LB7/turbo with intake, exhaust, lift pump, "12.40" tune, modded regulator and turbo inlet....and also the reason I later rebuilt it. :rofl: (I can laugh about it now)

So would you consider this more of a tune issue or messing with the regulator that caused your motor to fail not the hp. (For instance if you had not messed with the regulator and ran that tune but had ran say a bigger turbo to get the biger power do you think it would still have broke at those power levels, I am guessing you were trying to push the stock turbo/motor on fuel only to its max?)

Yes , ran 11.0 @ 123

This is quite OT, but explain how modding the fpr causes a motor failure please.

11.0? I'm not remembering

I just remember I was WAY quicker:coolspot:

I never seen anyone post that.

Thankyou

Yup. When we were playing with Casper's stock engine, we had run many passes (50? maybe more) at ~640HP. We cranked it up with a GT4202R, roughly 750HP IIRC (that was way back when 750HP was a lot, and a GT42 was large ), and were running about 11 flat at 120, and it didn't take long before it was smoking white at idle. Compression test told the tale.

Autopsy showed just bent rods, about .06" each, everything else was reused including the pistons. That engine had seen a lot of abuse, including >50PSI boost with the factory head bolts, and never a leak.

Since then, we have run from "rods only" up through 440+ CI fully built twin turbo engines. For us, no type of engine build has been 100% reliable, pistons being the limiter. No crank breakage. No cracked pistons.

Gimme some steel pistons, and I'll go 220mph. :woott:

I would like to see how these pistons would hold up. I think Mike Woods my have rans a set like them at one time.I saw these at SEMA in the J&E booth and had to get my hands on them and talk with the guys there. They said you have to run a special rod that runs a small wrist pin.

What are they made out of? What Rods run a smaller wrist pin to accomodate these pistons? Never seen them before....

Why steel pat? Aluminum cant get it done?

There just copies of the pistons i hade made 2.5 years ago for my pro truck...minus the coating. Once i sent greg pictures of them he had JE copy them.....like everything else he does.

The JE will work fine im sure, but there are major differences that cant be seen in a photo between the origonal and the copied part....

1800* and 21 passes tons of nitrous and no pistons issues'......

I seen them 3 years ago, so who did you copy them off of? oke:

What are your aluminum rods and pistons running?

 

[TheBac]

Why does Wade keep taking credit for every part ever designed for a Dmax? God, its tiring....

 

[McRat]

For reliability.

It has a higher melting point.

Aluminum can do the job for X seconds. X+1 is the issue.

Its called low self esteem, it makes people feel better about themselves. Dont give him a hard time about it, you know how them panzy jackwagons are.:roflmao:

21 whole 1/8th (cough... wimpy... cough) passes? OMG!!!

At a single national event, we ran Casper over 20 quarter passes at a higher HP level than you're running, and our pistons were OK too. They were stock pistons. Didn't see you there. It was the Finals (surprise, surprise, I guess your invite got lost in the mail).

When you get some seat time at the track, come back and bless us with your experthood. Until then, STFU about surviving several half track passes.

It's pretty rare that you'll see me trash talking other folk's racing efforts. But when it comes to your nonsense, I make an exception. You've trash talked just about every diesel racer on earth at one time or another, so I'm trying to speak a language you might understand.

Seems like the stock LB7 pistons seem to be pretty reliable from what everyone I have talked too has said:woott: Only wish the rods were stronger

 

[McRat]

PS - You should rethink that whole 1800°F thingy.

I'm not hitting that temp in 30 seconds straight at WOT.

It's not that the pistons aren't strong enough. It's that aluminum has a low melting point.
