    yup. that could be a very clever mod if it is proven to be effective. to prove that its effective you need to get back on the same rollers to get a good comparison.

    no rollers are the same. i could go from rollers at X to the rollers at Y and mysteriously gain 20bhp.

    rollers are only good for measuring gains before and after mods and having a visualisation of the your power output... thats about it

    Could it be that the first rolling road figure was wheel horsepower, and the second number was before drivetrain losses, hence the difference?

    either way its pretty much no help. each set of rollers has its own random number generator for tranny losses too.

    just need to get it back on the original rollers! [:D]

    Sounds like a challenge to me!!!! the whole development so far has cost me 225 quid. is the mk2 8v head the same inlet fitment as the 2E mk3 ?????? the AGG manifold is best as its completely square in its body.

    no both figures are flywheel horsepower, RR sessions were done by same guy on 2 diff roads.

    i remember seeing those in the magazines back in the day. did they really get close to the claimed BHP?

    lol not really a challenge, thats a bit too direct, but im sure you wouldnt be against a quick comparison ;)

    will it be easy for you to get the car back on the original RR?

    yeh the guy who does my tuning has a 2wd road and a 4wd road in his workshop so it wil be on the original road that it was on the first time round. i had Omex throttle bodies and Omex standalone fuel managment on the car for a week or so and produced huge power but created a few problems!!!!!

    ooooh quick comparison sounds like fun!!!!

    race! race! race!

    would be very interested in before and after. if it so dramatic then the pb manifold gets it!

    it produces around 215bhp. but ..... its not about the BHP is about throttle response and torque etc coz with the Omex u can map (fuel/air/timing) 10 different throttle positions for every 500 rpm so u get max power eveywhere no matter wat gear you are in!!! plus u can load diff maps for diff circuits etc!!

    oh ... and it has launch control on it :p

    um .... 800 for the Omex control box. 51 for the wiring loom 1800 for Omex bodies and manifold and injectors are personal preference. i using Saab ones at the mo.

    takes about 6 hours to map it properly thru the whole range!!!!
