Throttle body cleaned! (with pics)

[Pasty]

Just thought I would put some before and after pics up of the throttle body on my 172 cup

Before:

Oily, dusty residue had collected in the 'mouth' of it, and also half of the chamber was caked in same.

After:

Thats better!

seemed to improve tickover very slightly

(please excuse crappy phone pictures)

nicely done, it looks like theres quite a bit of filing down could be done to help flow on this TB?

 

[Lagerlout]

I don't think the TB is a major restriction tbh.

Worth cleaning. Although ,my idle went crazy for a bit when I refitted it.

Can you see the bit that the screw screw into, that's a restriction to airflow on WOT on these types of TB, minimal gains but worth doing on a sunday afternoon imo.

 

[Martin_172]

there was a guy selling re worked 172 TB's on ebay with quite a bit of modifiying done but apparently they arn't a restriction and the 90 degree bend on the hose going from TB to airbox is more of a restriction.

Brake cleaner and a paintbrush, rinsed with more brake cleaner

 

[Simon_172]

can you use WD-40 to clean it? lol >_>

 

[zack40]

sorry to bump in guys! speaking to a mate whos putting a larger tb on his mondeo... is there a bigger one available... i know alot of ppl would say its not worth doing would just like to know if theres one available like off the v6 or something?
Thanks

 

[Gregg]

is the tb easy to remove? think mine could do with being cleaned as on 65k now so probably full of crud

No point as the TB is not a restriction on the sport.

 

[Neil G]

As above...filing down etc on this TB waste of time but if it makes you feel better then go ahead lol

 

[mattjk]

you cant just file it down unless you want a 2krpm idle lol

I'd argue that, we get very good gains with a 70mm body.

 

[caister]

Can you provide details of this???

 

[sideways danny]

what are you after? proof of gains or details of the conversion?

yeah yozzasport are testing their new one out i believe, its a stock one thats taken to pieces and then machined out and a larger butterfly is added (72mm IIRC but i maybe wrong)

same as this http://www.lohen.co.uk/shop/proddetail.asp?prod=LohenThrottleBody

 

[caister]

It would be nice to see proof of gains as weel as details of the conversion as I have always been told the TB on the clio is not the main point of restriction and I am interested to see how much of a difference it actually makes.

 

[manicmonkey]

yeah lots of people jumping on wagons and repeating what someone said about it not having an effect, but no hard proof

 

[sideways danny]

Needs to go hand in hand with a re-map. I've seen loss of power by just bolting on a bigger body (on other marques), but if you map for the extra air you're onto a winner. You do have to be careful to strike a balance between size of butterfly, and throttle control. Much bigger than 70mm and the throttle becomes like an on/off switch as just slightly opening the throttle lets in a lot of air very quickly.

Same I'd take his word over others aswell

The TB isnt exactly small compared to the ports.

 

[sideways danny]

as with pretty much anything, you'll get the best out of these things if you use mods that compliment each other. As you rightly say the ports are small, so enlarging and matching these whilst re-working the plenum for the large body works well. I'm personally not in a position to post graphs, which would be handy right now.

 

[Fred@BTM]

size isn't everything boys

 

[sideways danny]

that a confession?

 

[Fred@BTM]

noj ust everyone seems upset by their bodies

 

[Andyman]

Proof? What size do cup racers use?

Go figure ...

 

[mattjk]

Proof? What size do cup racers use?

Go figure ...

I dont know, What size do they use?

 

[Fred@BTM]

standard mk1 172 body

 

[mattjk]

lol enough said assuming its the same size as the FBW couterparts?

 

[Fred@BTM]

erm, i'm not 100% sure tbh

 

[manicmonkey]

how much are the teams allowed to change on the racers? i woulda thought they would have done it if they could, as every bhp counts

 

[Fred@BTM]

zero

 

[Dash]

size isn't everything boys

Only where it matters.
