opinions on setting rev limiter!


ITBs are nice if you can get them running right and you can afford the cost of a proper kit.

The bodged bike kits seldom work properly for a variety of reasons.
 
It sounds mental yes, but you could lose power. It's well known that ITB's are very difficult to tune. I can't explain why it probably wont help much on stock internals and I understand why you want to know that. I have the same mentallity and people often mistake it for stubborness while in reality you just want to learn and want opinions that have theory and experience behind it.

Go ahead and try. And please report back after you had a tune. Would love to know the results.

Oh I understand your thinking, believe me! If you feel the need to have ITBs go for it! :)

i must admitt, I am searching now for some information on ITB's and it seems that they cán have a very good result on stock engines.

230whp with ITBs on a K20 S with a no close hood, that can be achieved on my setup without ITBs and a hood that closes. Weird no?
Im pulling out 218whp on a mild built B; with higher compression would get me to 225whp...interesting no?

There is no right or wrong here on my side, over $2.5K USD for ITBs just makes little sense.
Go for it and get back to us and tell us all the facts about the gains or loss?

I understand but that was not what I was trying to defeat. Some people, me included, stated that gains from a stock engine with ITB's will be very little, if existent. And that it might even lose on power. But from my short research I conclude that this is not necessarily the case and that my former statement was wrong :)

oops, my apologies.
I agree, with you on the above.
There are lower cost and more proven/reliable ways of getting there.

Curious, would ITBs pass MOT out there?
 
I haven't got a clue. Civics/Integra's with a cat can have a maximum of 0,5% CO @ idle, if you have a Civic that on paper has no cat (no idea if they're out there) the maximum is 3,5% at idle. Idle when warmed up that is.
 
I will try it and see how it goez, no harm in trying. I have heard they are difficalt to tune and i cant even find a basemap for them so will have to get it done by someone who know. Cheers for the opinions and help guys :)
 
Are they a proper kit, or a DIY kit made from bike throttles?

they are from a cbr100rr, i made the kit myself but all throttle bidies are the same so providing they are put together well and made well then i dont see how they would perform any different?
 
They are not. The cam on the throttle shaft is designed differently on a bike due to difference in the actuator (twist grip vs foot pedal) so the opening rates are a lot different. This causes a lot of problems with tip in fuelling using bike throttles as they open so much faster than car throttles.

They can be made to work, but it is more difficult than proper car kits, and even they are a ballache.
