Default V8 Throttle Body MOD

Hey yall; I've tried the search already; I thought at one point we had a guy posted about the Stock V8 THrottle body Mod where the fins were cut off the throttle body to mimic the Holly performance one.. and also boring out the throttle body..

I'm looking to modify my stock one and wanted to compare what all was cut off (Im assuming everything) anyone know the thread that can hot link me?

Id buy a dremel I never thought I would use mine much but I do use it a lot. Comes in handy for various things. You can get one for 40 bucks

What did you do about the air hat bolt and bridge? I was thinking about possibly bending a threaded post.. seems the plate there looks like it would further restrict; if we get rid of that it might help the small little gain we get off the mod.. I think i seen spectre make a pre bent one too in the shape of a 's' sorta shape.

I suggest saving the material under the air hat mounting bolt and only cut out the rest.


See how it feels then decide on removing the rest I don't think leaving that small an area intact will reduce any gains you may receive.

Yeah i just see that bulky flat metal as being more restriction on air flow IMO.. Just like that little flat piece of plastic in the factory air hat; the aftermarket hats for the 'open air systems' aka (so called) CAI's have it too just different and in a different position; when i cut mine out it seemed the throttle response was slightly noticeable. half and WOT. low end its questionable.. not much a gain there other than trying to not restrict the natural air intake...

Exclamation

The problem I see with an S allthread fix is you may find your air hat will not seal 100% and may come lose on you.

Is a very minimal if any increase in power worth getting dirty air down your intake?

I say make sure the air hat seals 100% and just cut out as much as you can.

I question if you get any benefit from this at all its more mind over matter you think it helps.... I think it runs better.

How do you figure the airhat wouldn't seal right anymore? Mine seals just fine.

I tried a mod like that in the past with poor results we tried all kinds of things and found the air hat leaked the S fix has an inherent flaw in that it tends to have pull more to one side depending on how much you tighten the wing nut.

It is a bent bolt after all

Its more a Z than an S

I used a thick o-ring and a washer to make sure the nut both seals at the top and puts even pressure on it. The air hat sits perfectly on the throttle body for me.

Lots of Chevys (including mine) use an S-shaped air cleaner stud. They work just fine. If it were offset 6" or something, I could see it being a problem, but the way it is, it doesn't make any difference.

Well.. I'm finished with mixed impression..

First here are the images; not quite like the original but i think it gets the job done just the same. First it's 88 and humid as all get up.. so not a fair test but not as 'pepy' however I noticed by the real time MPG at different speeds i was +3-4 reading.. so I call that an epic WOOT.

I drove around for a good while to see if it holds while the ECM adjusts its curve.. so far its holding strong.. I'll have to circle back around on this but if it truly holds 3-4 mpg gain.. I'm going to LULZ.. but to be honest I probably assume it will only be 1 mile or so difference if anything.. but lets see what happens.

I was quite intimidated by this project once i started.. but once i got going on it with some decent progress it was better. I messed up here or there but i think i got it ok. Good enough for me. I'm not trying to create a drag truck or nothing.




This was cleaned 2 years ago....




Cut the flange off.

Thumbs up

Looking at the Pic you could have opened the side into that pocket just a little?


Smart thinking on the bracket I like it
