    My plan was never to use the adjustable air horns as the permanent solution, but rather to use them on the dyno to see how various lengths impact the shape and the height of the torque curve. ...

    The adjustable airhorns from Emerald arrived. Given they slide into the TB, they have a narrower throat than the standard 90mm airhorns (43mm vs. 45mm). They also don't have a flared bell mouth...

    Looking at Jenvey's site, the TBs for the 2.5L are available in 48mm or 50mm whereas they make them from 40mm-50mm for the 2.0L & 2.3L heads either under their brand or partners like Raceline. I...

    Thanks Tom, is that 10-15hp increase compared to a stock 2.0L, stock 2.3L, or a ported head? How does it affect the shape of the torque curve? Is it all at the top end or does the revised shape...

    There is too big a hole in the bottom where the engine once sat. I'd have better luck with the ass-engined car in my garage since it is related to this:

    Staggered is stock; I'm just surprised by the delta. 185/245 is more extreme with my ass-engined car. Even the 620R -- which by all accounts is reasonably powerful -- only has a 185/215 stagger. ...

    I thought the CSR used 245 rears, but the S3/SV used 215? Does that significant difference in front & rear width result in a lot of understeer?
