    With reference to a ForEx rate off here as a baseline for calculations:
    http://markets.ft.com/markets/currencies.asp
    {changable but as of tonight-$1.89570/GBP}** this will vary affecting calculations ** and only valid at the point of transaction.

    sem $825.00
    throttle $150.00 <<limited qty @ this price, else $320
    gasket $75.00
    carriage $150.00
    totals $1,200.00
    using ForEx from above
    sterling ex vat/duty total is xxx.xx
    3% Duty
    17.5% vat
    Totals: xxx.xx inc vat price
    UK delivery 9.50

    ForEx on 17.08.08 - 1 = $1.86480 Good ole UK economy

    Here are some flow numbers from www.cylinderheadtech.com using a stock 20V Small unported head complete with stock cams flowed at max camshaft lift of 0.380" @ 25in hg with the SEM Small Port - Stock TB Hole (60mm) vs Passenger Side Stock Small Port Intake.

    Head without Intake flowed 187.65 CFM
    Head with Passenger side stock intake Manifold flowed 162 CFM without Throttle Body
    Head with SEM Small Port - Stock TB Hole without Throttle Body flowed 194.4 CFM ~ Translates into +32.4 CFM, equiv. to 20% increase in air flow over the stock intake manifold
    Total Flow - 776 CFM of flow equiv. to being Naturally Aspirated

    NOTE: This is not an open flowbench test where a superflow is used as that of the 1.8T Manifold Flowbench Test Results. This is completely different. The intake manifold is mounted to the head then flowed together with the head.

    They are some good numbers on the gas flow, as the dyno results show 30'ish Bhp from a manifold!. Thats a 10-12% increase

    If i had a 1.8T I'd be putting my name down for 1 straight off, Badger5

    Post #3, shows the manifold alone, even on std throttle body size on largeport head version, outflows the std manifold. De-restrict further with the 80mm t'bodies and its gains again.

    Flowbench tests-UK Independantly tested

    The opportunity and offer came up for Flowbench testing my new SEM manifold in the UK, so it was sent off to JP from JNL Racing to be bench tested.

    What follows is his independant test report . Prior to the test, RMR was his favoured manifold. Now there's a SEM on order. :)

    Read on.. and enjoy. (thanks to JP)

    Hi bill hope you well,

    Do they make this manifold with throttle body on lhs(cyl1) ?

    Do you think it would work ok with my audi? Dan K. build

    Dan has ported the head(agu).

    P.s. how did you get on with that g.box you had of me, is it ok?

    they only make the mani in one handed as per picture I'm afraid. It with larger throttle body is bolt on power more so with the power you already have. There is enough meat in the largeport version to accomodate another 8mm width on ports to port match if desired.

    box is working great thanks. many thanks for that. got me out of a hole.
