I was talking with TWM induction, and they informed me that the first production run for the k series is out in 54 mm.

Of course, it will not clear any stock hood and by cutting them you are compromissing performance.

I was pricing them up the other day.. Thought it might make a nice christmas present for the car

 

[MI4K20]

hmmmm..thats only for a TypeS head correct?? whats the price on them

 

[midoriek4]

twm told me hood cutting.

If you're in slo cali bring your car by my pad i have a die grinder and a cutoff wheel I'll fix your hood right up lol

I was talking to TWm the other day and they said that the 54mm wouldn't give the best response for the engine and that Skunk 2 was just moving up to a 54mm from the 52mm... I was recommended for the best gains to run the 52's.. So it looks like the 52mm ITB's will be making there way across to my car...

aye bro. dont mean to thread jack but what is your redline in your car?

 

[non vtec]

8800 I know a couple of people that go past that go past that, but personally I think 8800 is about far enough.. From my Knowledge most Hondas handle about 500rpm more than the given redline and still handle being daily driven... I also have a soft limiter in my car at 8600 so it stops any damage happening up the top end... Its mainly there as a shift point...

when you cut the hood, do you mean like cutting all the way through the hood?

That's true in most cases, but when you have cams, taking the rpms up to 9k+ helps greatly.

Tom of Camp1320 is having a huge sale on all TWM ITBs.

Hello everbody,

I am interested to know what tests are done to decide on 52mm or 54mm ITB's. Any dyno tests on trumpet lengths also?

 

[Goku]

on the power band, what would ITB give you the most ??
midrange , or top end ?? and would you benefit from a set up with ITB when your road racing the car ??

 

[K2e2vin]

on the power band, what would ITB give you the most ??
midrange , or top end ??

that would depend on the diameter of the itbs. itb's have better throttle response then

how about for road racing like a short track (similar to streets of willow)
what would be the best size ???

I have to ask what type of "road racing" you will be doing as I am not aware of any series that allows ITBs anyway. Neither Honda Challenge nor the new Honda Cup SCCA series will allow them...

How do the Toda throttle bodies compare to the kit from TWM.

What are the pros and cons of each?

Any realitive info is apreciates as Im in the market for throttle bodies in the near futre.

Price for one…Toda is way to expansive…you can get the TWM almost ½ the price.

The quality Toda is a lot better…

Size Toda is 48mm and TWM is 50 to 54mm…For the K motor it like it big…48mm is not enough…

Sometimes the Twm idle is hi but when you snap the throttle it goes back down…

That is sometimes..

 

[non vtec]

The TWM idle hassle we found to be one of the butterflies doesnt close up enough, if you are keen enough to machine it back you could get it to idle better.. as for the hi idle I think its mainly a problem when they are new as mine doesnt idle hi (have a sticky throttle) as much any more...

But hey when the car is only used for racing it doesnt really matter to much..

Will be coming out with ITB system for K20 in near future that fits under hood of RSX with throttle bore options of 48/50/52 and 54m/m, thick wall casting for porting etc, will have built in vacuum tree for clean application. www.haywardperformance.com LHP
