i get my car dyno tuned every spring and its usally spot on. i stay just below 12:1 in the high R's in boost and dont see any spikes with my wideband. idk how to really judge tune quality other than saying its street driven and ive never gotten less than 35mpg highway on E85 at my full power level. seems good to me but i guess i cant compare it to a known GREAT tune

well its not a base map. I know guys that thing a basemap is a tune.

I dont know if leed is still running his stock b18, but I think he was putting somewhere in the range of 450+ on stock internals. But its a top notch tune!

im just thinking if that bottom end is already done we could put it together with the ls bottom end instead but that raelly doesnt make sense with a brand new built head on a bottom end that im nervous about reving past 7

all i got to say is that seems far fetched to say they don't stretch when making considerable hp.


but then again this info is coming from the guy who said mini-rams boost creep  :-*

Horsepower is a compressive load and has nothing to do with tensile loading, which is the only load the rod bolt recieves.

I said piss poor wastegate angles cause boost creep.  Have you read Maximum Boost, or any other basic primer on the subject?

I'm sick of you arguing with everything I say not because you disagree on some factual, physical, theoretical, or first hand experience level but because you don't like me.  Either emit some tech from your cumtrap or you're gone from this site. I can make that happen real quick, asshole.

And I get this in my PMs:


also you have yet to say you were wrong on that mini-ram that i built. so don't yell at me when your the hypycrit.


Fuck you, dude.  You built a manifold with a wastegate exit that required the exhaust gasses to turn tighter than 90 degrees, I pointed it out and that it was a problem at low boost, and when it was pointed out the car had a 15 psi wastegate and was going to be a track vehicle I said oh that's okay then it'd work fine for that. AND THEN YOU FLEW ALL OVER ME ABOUT IT LIKE I DIDN'T KNOW WHAT I WAS TALKING ABOUT DESPITE DEALING WITH BAD DESIGNS FOR A LIVING.  Do you know what inertia is?  You dont blow air in one direction and have it magically do u-turns because it wants to take a scenic route.  Divergent and convergent merge collectors are used for a reason.  

How about you do two things for me?

1) Open up Maximum Boost and look at the pretty picture of the shallow angle divergent wastegate exit on the 25 year old F1 car.
2) Stop arguing with everything I say, in multiple threads, on a non-factual non-logical level.

Your a fucking idiot arent you?  

HP has absolutely nothing to do with the tensile strength of a rod bolt. Piston speed and mass are the limitations of the rod bolts.  When a piston/rod is on the power stroke, its forcing the rod down on the crank, the bearing shell and oil wedge take the beating, not the rod bolt.  Power has little to do with it.

i think the same people who came up with the idea that rods bolts need to be changed decided block guards were a good idea.

then they obviosuly do it so people like you who actually think they would sell hardware thats too weak and make them feel like they are getting something extra in the deal.

ive yet to hear of a sinlge rod bolt failure other then some honda tech faggots who heard someone that knew someone that had them fail, meaning the person was a retard and fucked something up and blamed it on that.

there JD i asked a question :'(

You remember the early Eagles that had the bad rep for having a small rod bolt?  The ones Jojo Callos made 1200 whp with on a bet, and then ran that engine for a season with no failures?  Why did they upgrade that hardware since it's obviously not needed?

The answer is simple, they "upgrade" hardware to satisfy no nothing faggots who talk about shit they don't understand, and can't understand even after it's been explained to them 3-4 times.

The so called upgrade also in some cases increases rotating mass if the boss area of the rod is enlarged to handle the larger fastener. (usually you try to reduce it)  Look at some of the shit the cup cars are running now.  6mm titanium valves, 20mm wrist pins, Honda big end rod dia., etc.  Bigger isn't always better, afterall isn't that now why imports get some respect. 

Also, Shot-peening does not increase the strength of a rod or any other component, it merely relieves surface stresses, to help reduce the chance of a fracture to form.
