Modified 48mm Throttle Body mark 2.

8 years 5 months ago - 8 years 5 months ago #55285 by Whiz
Well my first real bodge mod so when I get time to fit, hopefully works.
Used some epoxy resin from poundland to fill the holes in two stages after slightly filing the inside of holes for it to grip to.
Little filing to smooth out and then to the little screws to decrease their profile and hopefully get a result. Even if it just works as a normal one without any gains will be a result.

Here's what I removed to improve airflow through the throttle body.






Phase 2 - I swapped the epoxy resin, which filled the screw holes, for some 'Quick steel' with more robust properies.


Quick steel fix I hope for butterfly...

Cut off quick steel.. there seemed to be two parts to it. Equal ball of black and grey stuff and using cold water, just a dribble , to mix and soften. Put some on hands to so that it doesn't stick to you...
Rolled into ball and then halved, pushing each bit through hole and spread slightly either side...

A quick file to be less protruding although will keep a slight lip each side - like so...




In situ :woohoo:

Its as good as a new one :) Any problem? Poundshop usually has something that will help along the way.

It wasn't that nice looking when I got it lol I didn't even want to touch it to start with lol

Silly question perhaps, does it matter which way up disc goes now that it's flat? It slotted in and closed like that but would that normally be upside down how I've got it?

Whiz, you have the disc or butterfly in the correct way. I am quite sure that it doesn't matter which way you put it in.

Looks like you've made a good job of that Whiz, well done

Great effort at this mod Whiz. The mod itself is one of your first and it's commendable that you've taken this on at such an early stage. :broon:

A lot of people are put off doing this mod because they have no soldering gear or are not confident enough to play with soldering. So, it would be interesting to see how the 'Quick steel' holds up. It's properties seem to be quite impressive - click click.

I think that you have done a good job with the application of the 'metal plugs' to ensure that it can't really pop out into your engine. Fingers crossed. :)

When it's all dried and cured and back in place, can you take the car for a good spin and let us know if you feel any noticable difference in lower end torque response and power and/or anything else you'd like to add.

Again, nice job and thanks for sharing it with the forum. :broon:

Thank you. I did draw my inspiration from that :-)
But in addition I filed the protruding ends of the spindle screws too.

What screws? The spindle screws? They still threaded in but just the tips flattened flush with spindle...

They should be filed down and once done why fill them?

I can confirm this held up to 60 miles of driving, both cool and calm.. and not so lol. The tb held up brilliantly. Response improvement is actually much sharper than I expected and the rpm needed reduced too. 70mph was 3200-3300ish and now been 3000-3100 so engine sounds calmer.
