I switched from an elbow to a 4150 accufab and it was a day and night difference in my car. Between that and some tuning I went from 11.60 @117 to 10.70 @126.
How much do you guys think that intake and a 4500 will pic up over what I already have.

LXR intake Yes they are available in 4150. BTW, The trade name of our cylinder head and manifold is LXR by Performance Induction. The cylinder head line was previously ETP. I bought ETP out of the cylinder head line and did not come up with a snappy name for the manifold until a few months ago. We are very close to releasing both L92 and cathederal port manifolds too. The manifold in the picture is a limited production piece due to in sufficient material for the flanges and we had to weld on new ones. We have to finish 1 thing at a time though. The cylinder head project has taken a long time to complete and sort out. Just wanted to let all the guys that I have been recieving messages from know that. Thanks Allen for posting your results.

I'm doing a top LS3 swap now. I had to go with a LS3 OE ported manifold. I want to go with a intake setup like this. I'd like this when I do a custom cam swap with this type of intake. I never thought the elbow setup was efficient.
