I would like to try and 'decrease the stroke' and 'increase the bore' and keep aprox the same engine capacity and see how hard you could get it to rev.
correct me if i am wrong, this would increaes top end power but kill the low down torque?


you wont get a big enough bore to get a worth while decrease in stroke to make it worth while. which is why said to go for 3.8L with a 40thou bore and a shorter stroke.

my brother in law uses 4 litres as his speedway engines and he smashes everything in his class. i know they are speedway engines but the newest one got dynoed at almost 400 hp. there was a huge difference in the brand of headers/extractors with pacemakers being the best. i guess what i am saying is that these engines have huge potential.

how would oversizing the bore 40" decrease cacpacity? unless your talking about bore to stroke ratio or something??



it wouldn't.
what i was saying is decrease the stroke to to the piont at which you get 3.8L when using a 40thou over bore.

you would end up with a square engine at about 93.3mm stroke and bore with a piston speeds of 4285 at 7000rpm
as aposed to 4561 for the stock stroke.

you'd also get a 6mm longer rod which will help alot witht he poor stroke rod ratio the engine has


i smell something someone should try when their bored ;)


Ohh s**t yes!! I would love to see this done. Would be a really interesting experiment! 8-)

400fwhp would be well over 200rwkw. id like to see what was done to achieve this.? any further info?


and spinning a 4l to 8 grand.. that id like to see. the piston speeds would be absolutely phenominal, the weight of the piston would be incredible.

still dyno graph?

200rwkw+ seems the norm in speedway racing. Huge cams, big carby's and methanol all help.

200rwkw+ is somehow achieveable, fair enough.. With great difficulty and no driveability.

But revving to 8 grand?? I call s**t. Thats beyond ridiculous.


Cheers

seems to be alot of claimed 200rwkw+ speedways engines, and alot of smoke being blown up speedway racers a*** from a few people on this site.

still havn't seen any proof of these engines or proof that they are in some way streetable and would even run on 98octane petrol.

which makes it all pretty much usless, as almost all of us here are playing with our daily cars, not race cars.

there is no doubt 200+ is doable, when dealing with a race only engine, but i'd sure as hell love to see a streetable engine with that output.

I'd also love to see some of these people get there hands dirty and put in to practice what they preach to every all the time. because what they are showing us isn't at all that impressive from people that talk it up so much

you know who you are :wink:

Of course they dont run on 98 and of course they are not streetable. If the existance of such engines bothers you just close your eyes and pretend they dont exist :lol:

yeah you guys are right...as i stated they are race engines and dont run on 98 etc..

but wouldn.t it be fun to chuck one of these in a cortina or something?
fun being the operative word...far from practical though.


the young bloke that works there as well has a 250 xflow in a TE that does a 12.(not turbo) that one has fully programmable efi, big ports, big compression...you get the idea. was in a mag a couple of months ago, can't remember which one. will find out. [/quote]

you usually have something worthwhile to read but that post was possibly the dumbest post i have ever read. There are lots of ford 4.0/4.1 motors puttiong well over 350hp in speedways cars.. how can u deny this? have u ever been to speedway meeting?

I don't think you'll have much luck finding people who want to give out dyno sheets of race motors.

Try finding out just how much power a V8SC is REALLY putting out for instance. Almost impossible, especially from a larger team.
