THROTTLE BODY Upgrade

[Edmond Ugljesa]

Hi I had a VP and I put a 5.0 TB , de baffled the manifold and an eBay resistor in the iat sensor. Home made cold air induction. As in I wrapped the plastic intake with 10mm foam, then aluminum foil tape. Fitted a 100 mm pvc pipe from air box. Down to the lowest part of plastic grille. Fully loaded with tools and over 300k on the engine I dragged of a standard VN in good Nick and lower km. Mine was a wagon. I had a lot more weight. Cheers.

The bellmouth was put on by holden because people complaining about VN being to jumpy. That s why. I removed it and instantly more responsive! Even before the 65mm TB!

In regards to the bigger throttle body on VN to VR. Yes. On a standard VP with the baffle in the manifold removed it made it a lot more jumpy. I put a resistor later in the iat sensor. Again a difference you can definitely feel. The baffle first felt better. But I scored a 65 mm TB and put it on . I thought it was in my head so I removed it. Took it for a drive. I only drove up the street and turned around. Put the v8 TB back on. Then I was happy. Felt crisp, nice punch. Don't forget the ECU relearns to a certain degree. Cheers. I recommend it.

You do one at a time! That s how you can tell the difference

I was just thinking again about the bellmouth removal. I asked about it over two years ago and was told it won't do much at all by removing it, basically a "Muppet Mod. The stock set up is slightly restrictive on mine, even with the V8 TB a dyno run told me that. I'm yet to mess with the BM as I'm convinced that it needs to remain on a NA set up VR Buick. I love a few opinions on whether I should remove it or leave it on place.

Plenty of people remove it with no ill effect mate, try it and see

Mani is coming off in a week or so, so yeah might tell him to leave it out. It could be the cause of the slight restriction on the intake side.

Each to his own. It made my VP feel jumper! Like the push in the seat feeling was more!

That s what I did. One at a time as my budget wasn't high. First was bellmouth, then iat resistor, then scored 65 mm TB from my brother to try and it all worked! Little bit by bit!

My ute doesn't set you back in the seat, even at WOT and I have 124rwkw, where stock is about 92-94kw. I even have 3200 stall convertor, 3.45s and could probably still be beat by a late model Hyundai in a 50m drag.
