Free Mods that don't work

I've got a spare LS1 intake in my garage, and my ported throttle body is due back this week. I have access to temperature dataloggers and chambers at work, so when everything gets back, I'm going to stick the intake and TB into the chamber, heat them up, and show that there's an absolutely negligible amount of air temperature difference at the incoming air outside of the TB, and the air coming out of the intake ports.
The coolant bypass is an engine bay cleanup mod - it has NOTHING to do with performance. If you consider it a "performance" mod, you might as well go buy some tornado intake spinny things and some exhaust turbo whistles - that'll probably net the same amount of power gained.

I saw that article. I just wish that they would have ran the dyno test after each mod was done to find out which of the free mods made the biggest difference and which ones did bumpkiss. This only shows that done together you can get a 10rwhp increase, but it doesn't mean that just doing 3 out of the 5 would have yielded the same result.

It eliminates the tubing running to the TB, and if you use one piece of tubing and zip-tie it neatly, it's out of the way and looks a lot better than ghetto-rigging a couple brass fittings that just hang under the TB. Plus, if you trim the coolant pipes off (not like you're going to be using them again), it makes the throttle body look cleaner, too.

i think free mods are just small ways to improve efficiency.. that all and the engine gains from it.. its already proven..
but i would say cutting weight is the best..

WRONG. I have had mine descreened for 4 years. Never had a issue with shift points, fuel mileage or any other problem. I did not have to retune the car because of it either. I only bought the HPT software earlier this year. I don't know where the issues of descreening came from but it must be from damaging the MAF rather than simply removing the screen. My car still gets 25mpg on the highway just fine.

MAF,MAP,throttle position,etc. are all used to determine load.
Speed,RPM,etc. are used to determine shifting.
To put it simply: de-screening a MAF is not a problem that requires black magic to solve for. It takes time,tuning software,some knowledge and a wideband to correct.

Bottom line is there are risks. If you cannot tune or don't have access to a professional tuner you are playing with fire with this mod.

Wow.... Just wow.
Conversation with Jon at TSP...
You: Hey man, I got 1000$ to buy a set of heads with.
Jon: I got a set, they will pick you up 40Rwhp.
You: Cool man, I will take them.
Jon: Well, I have a set also that is the same exact price that will pick you up 50Rwhp but you have to do ten jumping jacks after you put them on.
You: Nah man, I'm good... That seems like a lot of time/work for only 10Rwhp.
As close as I could get as to what this thread reminds me of... Then you have Redvert arguing with Nssane about descreening the MAF and people saying the TB bypass is an engine bay clean up mod.
Damn it man, just damn it.

Lemons I am in no way attempting to endorse laziness as you seem to be implying, see post #42 for my brief anti-lazy "get your *** off the couch" rant.

The TB bypass is an engine bay cleanup mod. It has NO impact on power - either at the crank, or at the wheels. How anyone can think that air moving through a throttle body that's about 3" deep, even at idle velocity, is going to somehow "heat the air up so much it makes you lose power" doesn't understand the basics of physics.
