    Anyhow dyno'd it hit 229hp and 196 torques

    this was with all the extra work i did
    Impressive result! What was the 'extra work'?

    replaced the cone filter with the carbon viper kit! not driven it yet but im hoping that will flow better and keep the intake temp down







    and the next mod im considering is the plx gauge to keep things monitored

    @mark i think reading your thread again im roughly at the same stage you were with yours im gonna be peplacing my spark plugs for higher power ones

    did you look into replacing injectors? and where did you fit the mini non return valve? as i've never even thought of that!

    gauge is an essential, do it quick. spark plugs need to be one grade cooler , not sure what you mean by higher power ?.

    injectors were ok at this level of tune. the NRV goes in the breather line on the injectors, it stop blowback through them on boost, gives about 0.5psi

    Air filters make alot of difference. I tested a few on the RR, ITG made the best power, 12hp over the Simota !

    do you know how much boost you're making ? (accurately)

    Did you fit a lightened flywheel ?

    not got a clue what boost it makes accurately yet!
    and once the gauge is sorted then im looking into lsd's and also flywheel and clutch upgrades!

    and am i right in saying that valve goes on the end of the pipe that comes from the intake boot and onto the injector vacuum pipes?
    as if its beneficial i'll order one now!

    Correct with the NRV yes.

    flywheel and clutch make a big difference

    dont suppose you still have the part number for the NRV?
    and which end went to the injectors white or black?
    sorry for all the questions! but never heard of that done before

    dont have the part number for the NRV. cant remember what end went which way either. easy enough to work out though if you blow through it.

    have you upped your exhaust manifold size and exhaust ? sports cat ?
    manifold helps keep it running cooler

    Big bore throttle body ?

    still on the standard exhaust manifold with a full stainless system but with the standard cats still in there!
    is it worth going for sports cats?
    as before the FI plans it was a question i asked and people said that the m44 engine needed the back pressure and didnt run well with sports cats or with a de cat!

    you was informed wrong there, maybe on a turbocharged m44 , but a supercharger works slightly differently with regards to back pressure.

    i think your current state of tune will give around 200hp.

    get all the other smaller bits done, they all add up. exhaust is a biggy, especially for the cooling side of things
