Hi guys,

Need to know what would be an alternative for a TWM air box in order for my ITBs to breath better. Its now all tuned with EMS and putting out 161kw at the wheels with a B20B blcok and B18C head. There is no room for room for a ram air pipe from the bumper as you can see from the picture below. I have thoughts of cutting a hole through my CF bonnet and putting an air scoop but it might look horrible.

Is there such thing as hood shaker for the B Series? Anyway, need your ideas, thoughts, and comments.

Thanks.

 

window screen and hoseclamps FTW!

 

Guys around here seem to like this filter setup. Do a search for it

I think this is what I'm gonna end up using. for TWM stuff you would just want a blank backing plate to cut to fit the ITB's

 

I'd do the Jenvey mod.

 

What's the Jenvey mod?

I know with the older TWM stuff when they were three piece setups (manifold, ITBs, stack) and you could replace the manifold section with a Jenvey piece, but I thought that was to get around the fact that TWM did no research on the B16 setups and only on the GSR. It's my understanding that the port's approach to the b16 head is faulty. I didn't know you could mod the newer TWM stuff other than welding up the injector ports or whatever.

excuse my ignorance, please, I'm still learning.

I do have a set of 45mm TWM DCOE style ITBs on a Jenvey manifold for a B16, but they aren't installed yet. Like I said, still learning.

That would involve tossing the TWM's onto Ebay and installing Jenvey ITB's
Just get a fiberglass hood like this:

Lots of fresh air!

 

i think SMSP meant for him to get rid of them and get the jenvey's instead.
edit: b19coupe beat me to it.

donf can vouch and prove this to be the best itb mod

 

hi b19coupe. How would the air get into that reverse scoop on the hood? I know air pressure will flow from the hood up to the windscreen but how will it go back to that big scoop thing?

 

there is actually positive pressure there forcing air down at the itb's

 

have you cowelled(sp?) your hood? that area where the hood meets the windshield is a vaccum area....so when the hood is cowelled hot air is not blowing out, air from outside is sucked into the enginebay right where your itb's are
try it out, it only takes about 2 or 3 bucks of washers, and it looks ****** sweet

 

Cowelled meaning raising the hood up with washers?

 

I can vouch for the hood cowl trick.
I didnt believe it at first but then i tried a little experiment. I drove around for a bit,stopped, and touched the intake manifold. Ouch! Too hot to keep your hand on!

Then I go some nylon spacers and longer bolts and raised the back of the hood about 15mm.I drove around just like before for about the same amount of time.When I touched the intake manifold, it was only warm to the touch. I couldnt believe what a difference it made! So the spacers stayed on!
I didnt really notice any acceleration improvement though,but im sure its helping
