Success in this industry is based heavily on marketing and advertising. Forums are a fun place to share stories and 'sometimes' there are knowledgeable people with real experience sharing info. just sometimes.

I would trust Westech's results, third party, un-biased typically. I trust the dyno I use, the numbers it produces line up with on track performance (based on weight and speed). The customers they have are people that are often looking for small gains and have flushed out an engine combo for everything it is worth. I rarely see engines that are cheaper than 40K in the shop. He is a phenomenal carb guy. He doesn't over-inflate, sell engine packages that he claims will make XXXX HP nor does he advertise. He shows up at the NHRA races and races in Top Dragster. Word of mouth, track performance and reputation is what his small business is based on. He is continually humbling people that bought this or bought that which made XXXX HP on Joe Blow's dyno. Most leave with nothing to brag about. That is the REAL world, just sayin.

If your engine dyno sheets aren't several pages in length for one individual pull and include things like fuel flow (before and after), air mass measured (if done correctly!), BSFC and list specific correction factors it is hard to validate the engine dyno numbers until it is in the car and raced. They all help make sense of the horsepower and torque numbers.

Dyno calibrations are super important. It is amazing how many hacks are out there that own an engine dyno that don't have a clue how to calibrate or use their software and are not using all the inputs to acquire info needed to validate things. The average customer has no idea what they aren't seeing. It is equally amazing how many customers and end users are out there that get there XXXX HP engine and don't understand why it isn't performing at the track and are not educated enough to know they got screwed by their engine shop or who they bought parts from and the claims made were B.S. It often becomes a finger pointing contest in the end and no one person is holding ALL of the information to be able to point to the problem, it is he said, she said kinda story.

I agree with knowing and seeing fellow racers showing up at the track and not running the times they should based on the dyno numbers they claim. See that quite a bit,,,

1.8HP per cube is good power. 2.0HP per cube is stellar. 2.1HP per cube is outstanding and would be doubtful to see from any non-professional outfit not doing these kinds of builds in volume and would be the equivalent of a blind squirrel finding a nut, even for many of your professional shops who are not able to take the block from the crate to the final product and dyno. These kind of builds are not going to leave any stones unturned and will leave nothing on the table from cam and valvetrain design to compression ratio.

2.2HP per cube combos will use the best of the best and will be geared to racing only types of builds with detail focused on everything from super thin ring combos to fully ported and matched induction systems, elaborate windage control systems, optimized header size and design that capitalize on scavenging dynamics in the operating range the engine is designed to run at to spot on tuning using expensive fuels! I would expect to see that only from a one stop shop who specializes in NA builds (non-power adder) as the engine build often entails details and tricks not normally found in a power-adder type of set up, not always, but often. Otherwise if I see a post, dyno sheet or info being shared that claims XXXX HP it is 99% likely to be bullsh!t.

if Chris made 750 with a 414 even on a bias Dyno I want that as he used a Elbow and a 102 mm TB with a GM intake.

4500 should Cover that...it's a Tendicies for Hp Vs
