    Trust me folks , slide throttle is always slower than butterflies .
    Stroked engines are slower reving unless you re-address the rod ratio . This is done on mine by using longer rods , shorter pistons and also increasing the block height (alloy motorsport blocks are taller than iron pinto blocks).
    This means a 2.7 is still a fast pick up and not lazy . I will demonstrate this with a tyre smoking full weight street legal low 11sec 1/4 mile later .

      May be 15" wheels - bigger tyre footprint time.
      Never will i fit 15's or arches on my mk1 , i'd rather wheelspin and slide about , lol . Mind you it does that now so no change there then .

        It's all about the inlet airflow and the disruption to the airflow a butterfly will make.

          Still a longer stroked engine can't rev as quick - why have F1 engines been short stroke multi cylinder engines for years ?

            ht

            Marks not chasing the numbers,,,,but the engine revs that's for sure

            It had to be kept old skool to look at,,,hence slide throttle mainly hand made by HT,,,,,,Looks the part

              Yes slide throttle is cool and looks faster that's for sure , lol . Shame he's not getting it done in time for this summer as i was looking forward to going out in that . Doubt Nick will be getting his 2.5 engine working either now he's selling his Escort . Looks like i'll have too wait until i fit mine then .

                F1 is different , they can't sit in traffic or idle without blowing up either !!!! Plus an engine is £50,000,000 .

                    I've not , when you stroke an engine out properly then there's no reduction in rpm pick up compared to the original 2 litre configuration . Do it wrong and they get lazy so for example stuffing a massive big crank into a standard block height = lazy engine . Lazy = slow usually .

                      Also another thing too consider when building a race engine is torque . Big engines make more torque than small engines as torque is mostly capacity related . So the goal is too get as much torque as possible for as much of the time as possible without it being lazy (slow reving) .
                      That's what mine will be like , lots of power and torque but fast reving as well . If you compare a decent 16v pinto engine to a duratec or honda etc then the torque gap is massive . The lesser engines struggle too make torque and that's why they always lose in a race to a 16v pinto of the same capacity .
                      Morel of the story = stick with a Ford engine and then you can't lose .

                        310bhp without going mad and 350bhp if we push it with wild cams and mega compression etc . Whatever it is it will go like fooooook so i'm expecting low 11sec 1/4 mile times on street rubber with all the weight still fitted (so faster than a decent new supercar) .
                        It will look standard from the outside though so they won't be expecting it .

                          I love a Mustang but that's not my competition . It makes the same amount of tyre smoke though .

                            I agree with some of that but increased stroke makes the piston travel further up and down. Since the amount of time allowed for this movement is not increased, the piston speed increases with a stroked crank (piston must move a further distance in the same amount of time). Large increases in stroke can decrease an engine's ability to perform optimally at high rpm. Engines used at sustained high rpm usually will be better with less stroke and more bore (oversquare).
                            An engine with a stroked crank will usually produce more overal horsepower than an engine with a bore kit with the same displacement.

                            Just one question will you be using a dry or wet sump ?

                              Got dry sump on my 2 litre version but i might run wet sump on the big engine . As my new crank is massive it will smash through my dry sump pan so i need too replace it either way .
