Urgent how do I remove spindle from 1*2/197 throttle body?!?

[BenMc]

As title says really peeps cheers!

 

[Fred@BTM]

why? If you're thinking about polishing it etc don't waste your time!

 

[BenMc]

Sorted now anyway bud and making 64mm lol

 

[Fred@BTM]

and you're still wasting your time

 

[BenMc]

A guy on the 197 forum has done it on his and noticed a decent improvement so can't go wrong really bud.. Especially when the machinist at work is sorting you out

 

[Fred@BTM]

fair enough, but it won't make any difference!

 

[BenMc]

Not on it's own will nearly make difference but with other breathing mods course it will? Bigger volume of air can pass but not too big to be struggling ... If it doesn't work in the end oh we'll but least was worth the try

 

[Dan519]

I also believe it's pointless. any improvement is a placebo effect

 

[172Ben]

inlet is still the same size though surely

its like having a bigger plug, piping is still the same...

 

[gti6steve]

Pointless end of

 

[Russ_16v]

Agreed, the inlet is the factor you want to be working on, increasing the size of the tb will just make the throttle less progressive.

 

[BenMc]

Like I said on its own not much or nothing ... Sort other breather mods out inc porting etc should see some gains like that lad has off 197...

 

[Russ_16v]

Alot of work for no noticable difference - trust me iv been through it over the years, as has Fred, Danny and a lot of us.

Some even loose power.


Though are you talking about a 1*2 or 197 mate?

 

[BenMc]

197 bud ...

[BenMc]

Just some info I found...

 

[Russ_16v]

Well at the end of the day its your choice dude, Id still not bother - for the tiny increase you may get in bhp, you will end up with a snappy throttle - but its your car!

 

[BenMc]

Just using a spare one I've got so can change it back I can see where your con from too so cheers for advice

All well and good, but the throttle body isn't the most restrictive part of the intake system. I believe it's the upper inlets that are.

But if you have a spare one, why not play I spose

bernoulli theorem, read up about it

bernoulli theorem, read up about it

arggg, college physics lesson flashbacks

 

[Fred@BTM]

i did it at uni, i can see why students become drug users! boring hell!!!

 

[BenMc]

Just using a spare one I've got so can change it back I'll research it Fred cheers

I actually had to use that at work the other day!! FML
