Toby Posted January 31, 2011 Report Posted January 31, 2011 BTW Andy - what's it like being pinto powered? Wash your mouth out Really? I though you were going pinto (spit) powered?
andypipe Posted January 31, 2011 Report Posted January 31, 2011 BTW Andy - what's it like being pinto powered? Wash your mouth out Really? I though you were going pinto (spit) powered? No way. Dropped the old x flow off at HT saturday for a freshen up
andypipe Posted January 31, 2011 Report Posted January 31, 2011 Good boy! How was last season for you? Shit. Only got one race in. Massive brake problems and engine down on power. All go for this year
Toby Posted January 31, 2011 Report Posted January 31, 2011 Sorry to hear that mate. You need loads of power if you're brakes are stuck on! Good luck for the next season. Back to the topic?
mk1super Posted January 31, 2011 Report Posted January 31, 2011 I'd love a 2.0 x flow. X flows just have such a nice sound on webbers
w p e Posted January 31, 2011 Report Posted January 31, 2011 Will big stroke steel cranks still require the block to be machined? iirc, on a 84mm crank you need to macheine the cam, otherwise the rod bolts will hit the cam ? *I THINK* I guess a deasil (sp) crank would be a good upgrade, but no good for a high reving engine? but maby make a more torque'y fast road engine?? i dunno Not just the cam , the rods hit the cam and the crank hits the block so not easy work like you would know . toby its in the w/shop somewhere coming to an old s**t box soon
down2earth Posted February 1, 2011 Report Posted February 1, 2011 Going back to Ax blocks I see there is one for sale at www.trackstarracingservices.com but very pricey in comparison to the one that sold on PH the other week for around £500! What about creating a large capacity xflow but using all 1600 5 main bearing blocks inc the fiesta block but all subject to having the block/cam clearance mods i.e. 83.5mm bore x 88mm stroke = 1927cc @Toby have you seen the 'Replica 'L' Block with a difference' as its described ? available in iron and alloy for about a year now it will take a 90mm bore with ease and has been made to overcome the shortage of blocks to build FVA / FVC engines as period blocks are obsolete and the 'L' block proved unsuitable !

I think there is a limit to the stroke that it is possible to run in a crossflow. If you need to notch the cam with an 84mm stroke you'd need to cut the cam in half to get 88mm !
DAZZA Posted February 2, 2011 Report Posted February 2, 2011 Im no engine speclialist and admit to getting a bit lost with these bore and stroke calculations. I love the torque of a Pinto, just feels strong even in relitively mild tune. Even quick xflows just feel like u have to wring their necks before they do anything. So can someone just build one and take me for a spin and ill eat my words!
Nick Mexi-cos Posted February 2, 2011 Report Posted February 2, 2011 Your wish will be my command , we all agree the pound for pound the Pinto is a better option but there nothing like getting beat by a xflow and looking under the bonnet and seeing something the size of a lawmower engine thats just kicked ya ass , the whole point of a xflow is the ringing the neck out of it Revs We like Revs

Btw, what size tyre/rim combo are you running , my dads 4 door mk1 is calling me Sorry for the temporary thread hijack ,although it does have a 711m 1600 x flow fitted puddy
puddy Posted February 2, 2011 Report Posted February 2, 2011 Just found this snippet of info on the lcr forum as well ... "I was at QED today, on the counter was a bare twincam head which looked the dogs, all bright and shiny. They have 4 heads left out of a batch of 40 that they had produced, there will be another batch of 20-30 heads produced in the coming months. I got talking to them about some of their new products, the first was the front timing cover, they have started to reproduce these, they are currently being tested and should be available soon, they look to be correct in all respects, they are the TDC – 30 degree item ( sorry Peter) they will sell for £295 and will be ready to fit with water pump, chain pad, and front oil seal, QED will also offer them in bare form. They are also in the process of reproducing L blocks that will be correct to the original block, unlike the 1600 block produced by Cosworth in the States which has redesigned the oil gallery so that the block can be taken out to 2 litres. The L Blocks need to be tested and will only be released after they have been proved. QED have already produced a Ally L Block which has been in use for some time. I think the guys at QED should be congratulated on investing the time and effort in producing these items to keep our cars going." Rick the op is a very knowledgeable guy and not prone to b/s. puddy
down2earth Posted February 2, 2011 Report Posted February 2, 2011 @Fiesta Steve an 88mm stroker crank will fit the blocks as mentioned previuosly with mods - I know this on good authority and the cam will fit once neccessary adjustments have been made Some more bore / stroke calculations for you DAZZA 81mm bore x 88mm stroke = 1814cc 84mm x 88mm = 1951cc 85mm x 88mm = 1997cc 86mm x 88mm = 2045cc I think the safe Bore limit would be 85mm depending how good your block is but best to have it x-rayed to be sure so in theory you could have a 1997cc Xflow with your 1600cc 5 main bearing block with a 88mm stroke ! What ever engine you got just do what you can to satisfy your needs be it road/race/drag and everything else in between its all good fellow petrolheads @Nick Mexi-cos agreed mate. But remember torque does increase and the rpm at which peak power is generated drops in proportion which may mean you can avoid expensive steel bits in the bottom end to cope with the higher revs which a smaller capacity engine would need to run for the same power output. Bet you cant wait though to be out in your Ax tina should be lovely @puddy mk1 & mk2 cortina's are QED The 'L' block I know of is not a QED or usa block just did a bit of research to find the info about it, we are straying away from a 2.0 X-FLOW so I'll get me coat...although a Lotus block is a 5 bearing block ! ummm a stroked Lotus engine theres another story in the making

Toby Posted February 3, 2011 Report Posted February 3, 2011 Interesting post mate... @Fiesta Steve an 88mm stroker crank will fit the blocks as mentioned previuosly with mods - I know this on good authority and the cam will fit once neccessary adjustments have been made Has this been done on a crossflow or a Lotus? I believe the diameter of the notched out sections of the cam will be down towards 18mm diameter with an 88mm stroke. If the shaft is just a jack shaft for the oil pump and dizzy then this sounds fine, but a little anorexic for a cam - especially a wild one. I would like to think a steel cam is this set up and even then it seems like it might be a bit flexible - there's only 3 bearings on the cam and 4 on the rocker shaft which is about that diameter..... That said, if you have it on good authority and the engine is built and proven I'll eat my words.... @Nick Mexi-cos agreed mate. But remember torque does increase and the rpm at which peak power is generated drops in proportion which may mean you can avoid expensive steel bits in the bottom end to cope with the higher revs which a smaller capacity engine would need to run for the same power output. Bet you cant wait though to be out in your Ax tina should be lovely This is all true but....can you get an 88mm stroker crank that's not steel? And what are our concerns when spinning a crank? It it crank speed or piston speed? The longer the stroke obviously the faster the pistons are going (further to travel in the same time). This puts loads on the con rods, pistons and not to mention the crank. The reason a small crossflow will rev is partly because the demand on the heads breathing capacity is reduced. The bores are similar on all the crossflows so we are talking about the stroke in particular. As you increase your capacity (purely by stroking for the sake of argument) the speed of demand increases and the abilty for the head to cope reduces - hence, as you rightly say, the revs drop. This is an indication of the increased piston speed. This increased piston speed is what will make things fall appart - potentially!

Couldn't have been put better! lol Apprt from the agreeing with the Pinto bla bla - and even if we did we wouldn't say it!
Toby Posted February 3, 2011 Report Posted February 3, 2011 @Toby have you seen the 'Replica 'L' Block with a difference' as its described ? available in iron and alloy for about a year now it will take a 90mm bore with ease and has been made to overcome the shortage of blocks to build FVA / FVC engines as period blocks are obsolete and the 'L' block proved unsuitable ! No I haven't mate - sounds like I need one! And a winnnig lottery ticket!
Toby Posted February 3, 2011 Report Posted February 3, 2011 toby its in the w/shop somewhere coming to an old s**t box soon I'd have a look under a great big crossflow shaped pile of dust! Will any of still be alive when this is finished? I hope Nick's paid you already - he'll never afford it out of his pention money. Oh and you spell Cortina like that!
Toby Posted February 3, 2011 Report Posted February 3, 2011 Btw, what size tyre/rim combo are you running , my dads 4 door mk1 is calling me puddy Nice car mate, you can help him with that just a soon as yours is finished!

Oh and you spell Cortina like that! state pension toby , looks like i will be fitting lawnmower engine in the old girl , on the point of revs iam hoping mine does hold out and still rev a bit as ive gone really short with pistons and long rods ' not xflow pistons '
puddy Posted February 3, 2011 Report Posted February 3, 2011 Btw, what size tyre/rim combo are you running , my dads 4 door mk1 is calling me puddy Nice car mate, you can help him with that just a soon as yours is finished! Mine ain't coming out again anytime soon I am afraid, x flow mk1 tina is definitely looking the way to go,we need to meet up and discuss this mate puddy
Nick Mexi-cos Posted February 4, 2011 Report Posted February 4, 2011 Thats the Way Puddy get toby to build ya a screamer Xflow , 2011 the year everyone goes back to basic XFLOW YEAR
