ITB + LS2

3.5 TB + ProFlow

OMG

OMG!!

I needs this on my 4.8!!

Now add 180 degree headers...

mind blown....

I've been reading up on ITBs all night. Awesome thread. Mmmmmmm 180* headers make me tingly

I wonder how fast a stock 4.8 rotating assembly plus solid lifters will spin before it grenades.

If I was doing a V8 with ITBs it would be in this fashion:

So far 7700 rpm . . .

I agree, but IIRC that manifold isn't cheap by any means.

OBX LS1 ITB ~$1300-1400

Peeps bag on them since they are knock offs. Apparently, the the butterflies like to stick.

All of the other options (Jenvey, Harrop, etc) are ~$3700+

No, but I figured I could use a 5.0 lower GT40 manifold and fab up the 90° from exhaust pipe or something.

Of course this wouldn't be for an LS ... oops

Hmm, I wonder how big a batch I'd need to order to get the Chinese to turn that manifold out with a common ITB base pattern in zytel like the stock one for under $100 a unit.

That would be awesome and you would be rich!!
