actually you probly wont pick up anything other than a marginal gain. probably not even noticeable. not unless you are running a very consistant set up. ei slicks, stalled a4, full drag susp, etc etc. if you are running a stock suspension, stock tranny, street tire car...the margin for error increases by a lot and any small hp gains that this intake will give you, will be much harder to be realized in your ET.

I've read in other posts that you will trap 2 mph faster but not notice
difference in ET.

Gave me exactly a tenth on my cam & bolt on car so something less than that on stock internals.

Yes my cammed, bolt-on, stalled, 3.73 geared car. Mostly Stock suspension w/o front sway bar and M/T Drag radials. Just BMR lower control arms and relocation brackets.

i was hoping for a solid tenth....i have headers and everything and drag radials, lid, ported TB all that good stuff so i think a tenth is reasonable guess for gain...

On my 98 automatic, I'm in the 8.20s-8.50s @ 88-90 mph in the 1/8th mile with the most basic bolt-ons and with stock 3.23 gears. Of course, I just keep spinning my *** off the line.
