Why would I be butthurt exactly? I make more power currently with a liter less. Yea I am fully aware that in the grand scheme of things the big gun 4.7/4.9 can make more power. However being limited by the iron block or rods like yourself it does no good to make more power. It’s not a money thing it’s knowing what blower size fits my needs. My car would be slower with a 4.2/4.7/4.9 pullied to make ~1200.

Whatever works for you man, your opinion...like i said earlier, depends on your goals

That’s where you are wrong. It’s not about desired boost levels. It’s about your desired power goal and maximizing average power in a given rpm range. The heat argument from over spun 2.65s has no validation. The Weir racing car stays below 107IAT2 spun to 27k over a mile for example. Lazy boy is a perfect word to describe a under-spun twinscrew. That’s why a overspun 1100hp 2.65 will gap a 1100hp under spun 4.7 car all day with everything else being equal.

I guess if I had spent my money on something (anything) that is now challenged with contradictory facts (charts, graphs and engine dyno results) on a public forum, I would kick back also...............As I mentioned, I am not interested in overspinning (or spinning to the max), anything I own. I have found that in 45+ years of playing with cars, spinning things to the max only shortens life and/or damages stuff. I guess if you can afford that, more power to you. On the other hand, if you were shopping "best bang for the buck" because that is all you could afford.......Good luck with longevity on the big spins.

Another question that I have for the TVS diehards..........

If the TVS is the best blower out there (even best bang for the buck), Why would ANY 2013/14 GT500 owner ever replace their blower with something other than TVS????? The majority of 2013/14 owners that I have read about in their blower upgrade threads/posts are not changing out their oem TVS for some sort of "updated/upgraded TVS".........why is this????

No facts were presented just bias blower stand results with no real word dyno results to back it up. I am not interested in losing races with a under spun 3.6. The Eaton rotor pack is known for its longevity and is one of the reasons it’s used on OEM stuff. I had the opportunity to get a 3.6 and declined actually. Pretty happy I did given the results of my 2.65 so far.

The majority of them have upgraded to a better 2.3 case or 2.65. Lmao

I agree oem choice is used for longevity, they have to stand behind the warranty, but that is ONLY in the oem configuration/tune. Once the oem is extended past the oem specs. (modded/pullied, tuned), that all changes and no longer pertains to any "oem" longevity..........but I know you knew that also........

It is great that you are happy with the blower you have chosen/installed, that is the name of the game when modding.

Must have missed that memo, did a 2.9 on the 11, 3.4 on the 14.
To be fair, we are talking a few years ago...( 2011 / 2014 )

^^^^Yep, that is what I see on the actual owners threads, most all of them.

The TVS was sold to a earlier year GT500 owner for a "best bang for the buck" blower, and they (the 2013/14 owners), moved into a larger blower with "expansion room" without the blower having to squeal like a stuck pig when spun up for some power.

Good thing I didn’t say all of them. Using this as a reason why bigger twin screws are better is just another logical fallacy.

18,000 rpm. remember boost is just a measurement of restriction.
Of course but what I would like to see is for Kenne Bell to follow up the blower stand test with a same day dyno test if you think the VMP results are skewed.

Never said "better" about any of this because I have no first hand test data or first hand test equipment to state anything about tests or variables. Once a blower is put on an engine in a car, and we are now putting all of the variables into the equation, everything changes.

I like the KB tests, blower change/test only on the same engine in the same controlled environment........that takes ail of the variables that are attached to the engine and behind the engine out of the equation and we are comparing blower performance only.

Grabbing someone's chassis dyno test from the internet is like internet bench racing........The foolish just sit back and nod their head in agreement.

Then why would you even mention oem longevity if it does not apply here?, that is why I asked.

Are these Gen3 and Gen3R's warrantied for the length of a Ford powertrain warranty? If not, the oem Eaton rotor assy. in this discussion means nothing as it relates to Ford and oem Eaton rotor pack longevity.

Well, you know the 2.65 will also clean your house and cook your dinner, so you fools looking at other blowers better get with it.

Yep, and I appreciate that, I like when others run around and do my work, all while I sit back in my easy chair (Lazyboy). It's called "working smart".

This is failed logic 101. Why can’t you control the environment with a chassis dyno test exactly? Why can’t it test blower performance?

I didn’t mention warranty you did. My oem reference was simply implying Eaton rotors are known for their reliability even once over spun.
