He wanted more.....NLS road racer round 2. stage ITB's!

i have seen a lot of the option 1... First time seeing such small filters.

Those look like motorcycle filters.

[M3NTAL Kev]

Its doable

It's might be a good idea to move the filtration further away from the air horns by using an airbox to smooth out the flow and reduce turbulence at the air horn opening. Years ago a bunch of us noticed this while tuning our e30 M3s on the DTM CF airboxes.

may have a plenum like a true race car has.

may have a plenum like a true race car has.

wouldnt that hinder performance...? i mean, usually on plenums with side entrances, cylinder one gets lean (too much air in) and cylinder 5(in our case) gets rich (too little air)

with individual filters, then all of them get the right ammount of air. Unless of course that the plenum was for the dd...

anyways, just wondering.

It depends on the shape of the airbox and volume of the plenum. You have to consider the flow of air into each trumpet. Having filtration that close to the trumpets may slow down flow and create turbulence - though it will sound fantastic. Keep in mind every modern race car with ITBs that you see runs some form of airbox.

BTW, that airbox looks really nice. TWM has some great components, but I don't see anything for the 5cyl. yet - the roller throttles, if modular would be great.

that was an example....
MOST true race motors have them. and it won't hurt.

[Bennett@C2Motorsports]

sooooooooo exciting!

[JC@DouglasVW]

Nice work Josh, I am jelly of the ITB's.

[spdfrek]

[nunumkv]

Sell me ITBs?

[brian81]

Id imagine the engine would not last nearly as long with itb. It seems like more of a track car so I guess its fine.

Incorrect. Here's what an M63 engine looks like with the cover off. 8 cylinders, 8 throttle bodies, 8 nasty looking runners.

My neighbor has 202,000 miles on his '01 M5 without any problems, if you don't count a lot of tires worn to the cords.

Whattt thats freakin crazy man, had no ideas those engines were like that.

All of the M cars have had ITBs with the exception of the US Spec. e36 M3 and the recent 1 series M.

This is incredible!

Looks awesome!!!! Subscribed

Im in.....

How much??

[pete@integrated]

that was an example....

Most "true" race motors need them because they have a mandated restrictor they need to breathe through, or two.

Why was this on FB before vortex??

Looks awesome.

Maybe this is why I never heard back from him today

so....the tehITB's i paid huge money to get custom built, waited 2 month longer then told...didn't fit at FIRST. i gave them 20+ pictures. measurements of everything even hood and rad clearance. EVEN gave them a oem manifold....ARGH!! oh well... with some machining and fitting...they NOW fit and fit well. plenty of room for a plentum if needed working on them more all this week. more to come.

Looks awesome.

yes, that and i just got back from one lap and i got hammered with a week and a half of return emails, calls, meetings and what happened when i was gone....sorry, just way too busy, i PM'd you a few times....so don't roll your eyes at me, i'll knock them out of your head buddy....and you DO know i'm joking with you! get ahold of me today...i'm 80% caught up! i'll do what i can to help you with your issue....but i'd say just re time it. and rotate it around theright way.

you can buy 2 turbo kits for this....fyi. because there is not kit. its ALL custom one off, must be done in house here.

plenum

Plenum volume seems a little small, no?

That's what I was thinking too.
