A couple of the drivers did, all that happened was they got taller.

(Sorry, I could not resist)

Others do not run stickers of what they actually run because it does not look as cool in the magazines.

RDY4WAR, yes my Fram issues were during that era. First one was on our dragster. We did not have our dyno setup yet so we figured we would dial it in at the track like we always did. Fired it up and had extremely low oil pressure. We put different gauges on as well as in different places in the engi...

Having studied bypass events with pressure probes before and after the filter, I can assure you that bypass events are rare. With a 5w-40 oil, high volume pump, and a standard Wix 51515 filter, the only time I found a bypass event on that SBF was when the engine was free revved from idle to 6000 rp...

No wonder some people are detonating their engines to pieces... Very true. A friend of mine brought back an engine we built him because his uncle “set the timing by ear”. Whole new set of pistons, rings and bearings later we put it back to where it needed to be and told him to never let anyone touc...

Great question! Poorly atomized fuel and bad wet flow characteristics have a big impact. But last time I tried to stick my head in the combustion chamber which the engine running ended poorly, so I have to imagine what is going on based off of experience (of my own as well as others). Testing timing...

Performance engines are spoiled brats. When you give them what you want they are pains in the neck. Give them what THEY want and they are great ( just like my kid). Compression, cam event timing, chamber shape, spark plugs used, measured squish, fuel and afr, intake design and many other variables a...

When you say budget what are you thinking for the actual Budget? If I wanted a budget bbc engine that made good solid torque I might start with a late model 454 (gen 6). They are four bolt main and it’s cast crank and rods would do just fine in a well built “torquie” truck engine. You can use the fa...

When you say “cruising around” what does that mean? Local car cruise? Burger joint car show? Daily driver? Hook to a trailer every now and again? I ask these questions as the use is a little vague. Flat tops on a 4.25 stroke can be anywhere from dismal to north of 9 to 1. I would guess around 8.3 to...

If I have my own dyno and it makes 300 hp I won't get laughed out of town. As long as your money is green you will never get laughed out of town. They want good paying customers back. On a serious note, a day at a dyno shop with your engine could be infinitely valuable. A good operator has seen ple...

just be aware that Superflow no longer supports the 901's. Replacement electronics are getting really hard to find. I bought a new 901 in 1988 and it served me well for a long time. When I had a major electronic failure in 2017, I bought the "902" upgrade kit that eliminated all of the old electron...

I have no experience of those LS MLS gaskets but I have disassembled similar gaskets and used what amount of layers have suited my needs many times on high cylinder pressure Japanese turbo engines. I have done that many times with high compression race engines, but never turbo. Why pay double for l...

whether what he wrote is still 100% correct, outdated, or 100% false, you can still learn from it. Try and understand what his line of thinking about a given topic was, at that time, and worry less about the numbers. Maybe he's 100% correct. Maybe his line of thinking was spot on, but he had the eq...

"the EGT is the System's Speed ( Speed of Sound FPS ) you have to work with, and the "Timing" of the returning negative pressure Wave @ TDC-Overlap is where huge amount of TQ and HP gains are , so the earlier EVO event is ... the longer the Primary Tubes need to be . Now, does the use of methanol h...

No need to worry or be intimidated. Just plan it out well and put it together. It will be great. If you go to someone to have your system flowed, ask a thousand questions about tuning as well as how they like to see you maintain it between races. As said earlier, a clean system and great maintenance...

Thanks for the tips on how to better use our dyno to its fullest.
