Best Size T/B?


W80 YAU said:
So Kieran, would you say a bigger tb is fine for a boosted engine??

I have a Skunk2 inlet with skunk2 tb (either 68 or 70mm, cant mind) for my boosted c4.
My mechanic hasn't really said anything so far regarding skunk2 tb being too big so im presuming that will be fine then??

To be honest mate I wouldn't really know, when It comes to turbo setups Im still learning. So couldn't say Better or worse. Since im not sure Im not going to even try and give you advice, as it seems a lot of people seem to love doing on the net.

Not a big fan of giving unsure gueswork advice.

I completely see where your coming from, but im not one of those people that think "bigger is better". However a 3" intake pipe gave me an extra 5mph top end speed on a 1 mile straight stretch of road.

If you class that as a good analogy of proven gains then Im going to give up now as Im clearly wasting my time trying to help. I have writen up some substancial facts on what world know top Engine tuners use for their engines, take from them what you like. If you want to waste your money go ahead.
 
You're not trying to help anyway your basically trying to tell me im full of ****. If you think the stock intake pipe is the best just because its oem you need your head checking.
 
Guess it was useless buying a 70mm tb then for a n/a setup lol
 
Totally agree with Kieran here.

I spoke with my tuner (Henry Roy - who is very well known) when I was thinking about a skunk2 inlet and throttle body and he said it would be absolutely pointless and my car would be better with just standard inlet and tb.

I have heard this off many people now. So tbh I wouldn't waste my money on a big tb after hearing what many people have said.
 
I'm sure if kieran thought you were full of ****, he would tell you mate.
What he's getting at is that 5mph extra top end doesn't mean the car is more powerful.
Too many variables to say that!
Speed of the wind on the day, amount of fuel in your tank, passengers on board, etc, etc.
You probably did get a hp gain from the intake pipe, however I'm sure that on a dyno, it wouldn't be anymore that 2hp...not noticable in an everday situation.
And if your butt dyno did feel 2hp difference then you should be workling for dyno dynamics, as a portable dyno lol.

I was trying to help the OP of this thread. Also anyone else who is researching larger Throttle bodys.

You are inputing useless information and confusing the thread. With nothing but what you "imagine" is better. This>

Also you still haven't noticed this thread is about larger throttle bodies not intake piping, which although are both part of the intake of an engine are infact two different parts and influence in different ways. Considering you are yet to input anything intelligent or even fesably relevent. I would advise you reconsider suggesting that I am the one who needs their head checking or any other insult you may consider.

If in fact you still think that you know so much about intake dimensions/design then maybe you should give Cosworth/Mugen/Toda a call to promply inform them that they are dumb and are using Throttle bodys/intake piping that is to small.

:win: :win: Best Comment :win: :win:

I'll also add that, Abraham Lincoln once said:

"It is the measure of a man, that he can admit when he’s wrong"
 
Throttle bodies can be looked at like the top [wide opening] of a funnel, no matter how large it is, or how small it is or how long it is, the governor is the smallest port on the funnel leading out. In this case it would be the head of the engine. Once the head is addressed to pump more air/fuel the next bottle neck is the exhaust system...but that is a totally different topic right, Kind-a?!?!

This is not news to anyone building engines, really folks, really...

I would like to point out an issue with aftermarket TB's that use different metals; metal expansion! My large TB from skunk2 binds up when hotter than normal outside temps are reached. The butterfly binds-up against the TB housing causing a stuck open or closed butterfly. Taking the fun factor right out of the equation, not that there was a ton of fun added by installing an expensive TB. I can see that skunk2 has tried to address this very issue regarding the butterfly binding up. They have this coating all around the edge of the butterfly [which has worn out on my setup, causing it to again, bind up].

I say pass on this modification until you have a proper head that can handle flowing more air/fuel.

In terms of the TB your probably right, but i dont like the way you basically laughed at me when i mentioned using a 3" intake pipe. How can you say that terrible rubber pipe is better than a constant smooth 3" pipe? It's not. If you had been a genuine guy trying to help people fair enough but you come across with massive attitude! Just chill dude!
 
Sorry for the attitude.

But really just hate seeing people be given missleading advice.

Also still on the Fact this thread is about "Throttle Body" sizing!, going on about intake pipe is quite Irrelevant and missleading.

P.s the inside of an OEM rubber pipe is quite smooth.

Smooth is not always what you want, just depends on what you are trying to achieve.

Telling others to do something like "chill" will most of the time end up in achieving just the opposite. Just say'n...
 
Have to say kieran often offers lots of advise on here and has done for years now, That much is evident for any regular forum user..

Pretty unfair to say he isn't a genuine guy who isn't out to help.

:nice: he did also apologise..

Yeah apologised because of his attitude towards me. I was only giving my personal point of view and i get shot down like that! Don't think il state my opinion from now on if people belittle you like that on here.

No No dude, don't hold back your opinion.. when you say "on here" Thats not the way this forum is dude, If anything its famous for the opposite. :D

From a 3rd person point of view, i don't think he was trying to belittle you, but of course if you took it that way, who am i to tell you any different.

I think He was more getting to the point of saying, Unless you can show proof or evidence then its not worth posting the information.. that and the topic is on T/B.

I very much doubt it was personal, as kieran said it does get annoying when people post things saying it is best or better with nothing to back up that claim.

Honestly dude don't take any offence to it, Added the fact that this is all typed out so you can never truley gauge how someone is speaking. sometimes i type like i'm pissed off and having a Rant but i am very rarely angry.

but don't think you should hold back your opinion for the reason of how someone may have come across..

its only the internet buddy...chill :D

you are entitled to your opinion but if its completely unfounded you open yourself up to some criticism by those that know more.

I wouldent take it too hard, Topher is right

wish i could have said what i did in fewer words like this :nice: :D
 
Think You have taken this whole thread the wrong way.

I know I sound like a douch 90% of the time on here but generaly im just a bit blunt.

But (more bluntness to follow), advising "opinions" have no place when it comes to engine tuning. Engine tuning is science and physics. Opinions belong in the sections about looks and fashion. If you don't "know" something is benificiall or can't give any reason other than what you think/feel is better without any research then Its not really fair to advise someone else to spend their hard earned cash on something. Thus why I did't even attempt to advise W80 YAU regarding boosted application, as Im not sure on its effects.

Main reason in bold to why I jump on these subjects. As when I was still learning I used most of these forums as resource areas. Ended up wasting money from taking wrong advise. So when ever I know something to be a wast of money I tend to stick at keeping the explanation correct as much as I can.
