I've been building engine for many years and every thing u can name but i cant seem where to point the finger on this one .. heres the info ..

its a H motor car was on a good ok tune but was very rich 11.5-10.8 air/fuel
reving to 7500 rpms .. 15psi made 440whp on that very rich tune
I looked at his hondata map timing was around 25dreg on 110 octane

i pulled the engine apart for him just to check every thing out for the new season still ran fine before pulled . bearing looked good and all so i pull the rods out and look what i find (pics under).. all 4 rods bend oddy .. there IB rods I beam..
so now what im asking is do u think it was the cheap rods or the tune. I trying to figg out what to do since he needs new rods , its a h23 crank so theres not many rods out there crower or these and he do not want to spend the money on crower if he do not have to... let me know yah thoughts

 

Look at the small-end bushing, wrist pin, and conrod bearings. If they are scuffed or show signs of contact with the crank, then I wouldn't rule out the tune.

 

I've never seen that before...in for more info

 

Iheard that was called the S-beam rod.

 

no one can chime in?

 

wow those rods are bent to ****.......poor qualitly? or maybe the I beams are not meant to handle that kind of stress?

use a good set of H beams?

email jeff at IB and show him the pictures.....see what he says.

yeh i didnt want to start pointing fringers yet.. i know that the crowers are I beams

but on there site it says that I beams are made for allmotor.. so i know what there going to say
Im trying to figg out of theres any other reason this has happen , and has any one had this on a name brand rod

 

??

 

looks like it was just too much power for the rods which led to them bending which effectively led to lower compression...

id go with a better rod so this doesnt happen again...

any signs of detonation on the bearings or pistons, combustion chamber or spark plugs?

naw not really .. every thing look some what clean. only other thing i know about it is that he blew 2 headgaskets in the pass with this block he told me ..

but the main thing i was thinking can to much fuel with a long stroke that cause this?

 

so in 3days ,, no one can give me any info ??.. i know i cant be the only person who has seen this!

 

id say poor quality,

Ahh i gotcha. Yea i just asked him about it. Sounded similar because he had that headgasket issue and made similar power.

yeh he blew a headgasket running 22psi on a 15psi tune on pump gas lol

after he allready made 420's on 15psi

 

even all motor rods would hold 400whp.. how long has he ran the car, crank walk?? thrust washers were still in when u pulled the crank?

yeh i thought crank walk to when i 1st seen it . but thrust washers were still in there and all .. i have used these rods before on a 500whp b18c .. but i know they have a better rod to stroke ratio

something like that.. went from a 2.5inch downpipe to a 3 inch didnt touch the boost controller and did it by it self

the 2.5 had a nasty bend at the turbo tho ... thats why the 3inch free'd up so much more .. i been telling him we need to get back on the dyno or buy a wideband since we dont know how much more power that free'd up .. so it could be lil leaner at the same boost .. but its not my call or car

yea man i agree. It could very well be lean if the larger exhaust is causing it to creep that much more on boost.

 

damn, i've never seen anything like that before. in for more details...8)
