    Full Race engine.. how usable on the road ?

    Hi

    I'm getting a full race x-flow engine. How usable will this be on the road ?

    It's out of a national hotrod. Some of the spec is...
    All steel innards (crank,rods,pistons etc)
    Twin 50's
    Dry sumped
    blah blah
    180 bhp
    revs safly to 9000rpm

    Am i gonna be able to drive this on the road... as in how much of a bugger will it be to drive ?

    Cheers

    Craig

    You will probably find there is little useable power below 4,000 - 5,000 rpm, It's likely to be very cammy so yes, it's probably going to be a real bugger to drive down to the supermarket!

    Do i remember correctly that there was an article in Classic Ford about remapping the ignition or something to sort this out ? I think it was a mk2 escort that the engine was in. I think it also had a national engine in ? Anybody else rememeber this ?

    Cheers

    Yes I remember that.
    It was a mk2 Harrier I think and Northampton motorsport(?)
    did the biz with a electronic ignition kit and a rolling road etc.
    A peaky engine will always be relatively hard on the clutch and difficult to drive smoothly.

    ask the harris boys they drive their mk1's on the road ones a very highly tuned crossflow and yes it does sound a bit lumpy on tickover
    i think you will have to learn to slip the clutch and try not to get stuck in traffic

    Difficult engine in traffic, but with 180bhp and all steel innards it sounds worth it Wouldnt like to see how much MPG you get though, 15-20 maybe?

    Cheers, Gomp.

    I've been told that it will get 12 mpg... I pick the engine up tonight. I'll post some pics if you like, Wait till you see the clutch ! Speaking of. Anybody recomend a clutch that will cope with 180bhp ? I want to be able to use it though, that is push it down without going to the gym.

    I think it will be worth it with all steel innards

    Cheers

    My 1.6 x-flow in my escort gives me about 20mpg at the moment and it is standard, what do you guys recommend? A really good tuned, clean carb etc

    I had a Harris built engine on twin 48s in my kit car, Nothing below 3500 at 4500rpm it went mad, I span that puppie a few times very lively. I found I could live with the down sides for that much fun. Idled rough, slip cluth to pull away, leave big gaps in traffic before pulling away.
    Had a stanard escort english axle - it ate a few of them.
