    Re: Tuned Rover V8 ...disappointed!

    I had a Rover powered Pop. It was a lot heavier than people thought , it weighed something like 2700lb from memory.

    I dynoed the motor at 225hp without gas , we added the bottle and ran 11.5 with the wheels up.

    Its really difficult to get lots of power from a Rover , a Chevy is much easier and cheaper to make power.

    2700lbs works out around 1227 kg , pretty near the 1200 area I was expecting from the spec , like I said earlier I'm very surpised by that weighbridge figure for this Pop.

    Hi mate,this pop should be a lot better than it is,you say its running rich,it sounds like a carb problem.The rover should run fine with a good 390 cfm holley,check that you havn't got a rejetted 600 holley.Hope its been some help.cheers Paul.

    I took a Ford Pop hotrod in p/x on a 400bhp skyline Gtr i just sold..
    The 'Pop' is the green one on fleabay at the moment..
    The engine is a Rover 3.5 V8 that was all new around 12 months ago....its got around 900 miles on it now.
    Specs are:
    (SD block)
    A.R.P bottom end (mains, caps ,shells, rods)
    Big valve wildcats heads fully reworked, ported & flowed
    Viper hurricane cams
    Rhoads lifters
    cloyes timing chain
    Edelbrock performance inlet manifold
    Holley 390cfm performance carb
    Holley 600 lph fuel pump & Holley fuel filter
    Hedman headers
    Edelbrock air intake
    M.S.D electronic ignition Ecu
    M.S.D blaster multispark coil
    Mallory electronic distributor
    Moroso competition sump
    lightweight alloy engine pulleys
    Accel ignition leads
    NOS Cheater Nitrous oxide system.
    Transmission is:
    3 speed Borg warner auto box with remote oil cooler mated to a competiton propshaft
    Jaguar E-type rear axle shell fitted with strengthened halfshafts & diff

    I,m disapointed with the performance ....i know it was never going to be like the skyline but am i asking too much?
    The engine is running very rich, sooty plugs etc, i,ve had the Holley carb floats adjusted and the mixture screws adjusted but still running rich....is this the norm on this engine?
    I know the Holley can be a nightmare to set up!
    I would have expected more from this setup with the car being so light....
    Any ideas people?
    Hi, Are the heads reaily wildcat ?? As wildcat stage 1 heads are the best you can get for a small rover, (Stage 2 for a bigger engine) I wasnt aware that edelbrock have an intake that fit the wildcat heads unless you have the adaptor, In which case id swap it for a huffaker high rise. You are using a 390 holley carb which is too small and i wouldnt even use on a standard rover. You should be using 500cfm or even 600cfm imo. The cam you are using (viper hurricane) is just a mild fast road cam for a standard engine. If you speak to ian richardson at wildcat he would recomend a 248 mechanical one for this type, The compression should be around 10.5/1 and get a higher stall converter and you will be heading in the right direction. Just my opinion and going from experience Hope you do some tweeks with it and see how faster it should be.

    Re: Tuned Rover V8 ...disappointed!

    Standard untuned Rover consumes 365 cfm , are you talking 500 Edelbrock or Holley as they are totally different flow rates ?

    I had a webber which i belive is same as edelbrock when i had a mildly tuned rover. I was told that the webber 500 was a better carb to use on rover v8 than the 390, It seemed more responsive with mine.

    Yup, Weber IS Edelbrock but the flow rate is measured differently ie a 500 Edelbrock is not the same as 500 Holley ( if they do one ? ) A 600 Holley is HUGE for a 3.5 /3.9 Rover unless a large amount of work done to need it to consume 600cfm . Larger venturis slow down bottom end pick up , different states of tune for track and street
