Yes I do,,,,,,sort of...... not that they have missed (and the factor of 1/10th of a horse was relative to my usual of sub 350cc engines) here 1/10th is all relative but really equates in size, and friction differential to about 1-2 hp per item.
Not that they have missed it, but they dont see benefit in it. There are some items like slicing lifter bores I dont know if they are legal, but all those items have workarounds I do know are legal, If I can reduce 60-70% of my valvtrain friction thats a good start, and pretty easy on this motor. Phase II will have all those items.
I dont think nearly anyone has "Missed" items like that, undercutting valve guides for example, you loose reliablity and its labor intensive, on an 8 it can be good for up to 8-10, especially at high RPM......
Anyone is who is aware of these items can do it, WILL they do it is another question entirley.
I think most people know of these items but MOST arent willing to commit the resources to 1-2 hp. We will (to my knowlede be the first running crank scrapers on these motors for Stock Eliminator) whats that worth ? about 2 hp ? maybe a hair more ?
The coatings and treatments, really most of those arent for HP, they are to try to gap some of the reliablity problems that will be introcuced throwing in "the kitchen sink" Running a motor on the verge of desctruction is the best way in my experience to pull power. How many others are willing to turn their engine into a pile of metal shavings ? But I am....so is the old man....
Maybe this isnt a "Stock Eliminator" approch to things, i dont know....the only thing I do know is how Ive always done things, so this is a comfort zone and Im aware of the expectations from a point of having to do-redo things to maintain a running package at all times.
Like myself and others have pointed out, Were new to stock eliminator, so maybe these things are best left to another class (id be running a FED this year a choice) but I am playing the cards I was dealt , and the DP project are those cards. If we do things different that other "Stockers" no suprise, but the processes and procedures work and have worked for us, if they need altered we can alter them.
I go through 3 checklists on every item, 1 the inital checklist, validated by me, the second checklist a verification of someone elses hands and eyes, also bringing and correcting other items, the third pass by me again. I have a clipboard, and ask my dad, hes the MASTER of Preflight checklists. Is that "Normal" for stock eliminator I have ABSOLUTLEY NO, 0 idea but were good with it, and it works......so well stick with it....
I am 100% ok with sacrificing reliablity for performance. IF I go into it with full knowledge of the payoff and consequences. My dad, when given the options will as well ALWAYS take the one that makes us fastest, IF he has an accurate expectation in terms of reliablity were loosing. If I have to tear down and inspect inbetween every nat, I will do that, it "takes what it takes" simple....to me I guess....and the part I enjoy
No I dont think most people miss the things, I will bet the opposite, that nearly every builder who hasnt implemented these things did so for a reason, they saw bad ink on the balance sheet from reliabilty to performance potential, they made what choice they made for reasons that suit them. I HAVE built knowingly slow cars and bikes IF the payoff was reliability, but I did so knowingly and with purpose.
I think they KNOWINGLY choose not to do these items for a plethora of good reasons that fit their scenario, budget, goals and knowledge.
Cheers

I just don't think you are going to be able to measure, coat, treat and degree in 250-300 extra horsepower. |
