Mike Posted December 25, 2001 Share #1 Posted December 25, 2001 Here is a very cool L6 engine calculator.lengine.zip Link to comment Share on other sites More sharing options...
ZmeFly Posted January 20, 2002 Share #2 Posted January 20, 2002 is this fairly accurate, or close. or is it just for fun. also a suggestion. why not include, shaving the head on the calculator. Link to comment Share on other sites More sharing options...
Mike Posted January 20, 2002 Author Share #3 Posted January 20, 2002 Not sure if it's accurate or not. It was sent to me by one of the members. I can't remember who it was at this time.Yes, it would be good to know if it's accurate. I don't think it was put together for fun.. It's meant to be something for actual engine work.Hopefully the person who wrote it will visit the site and let us know about it. Link to comment Share on other sites More sharing options...
Ben Posted January 22, 2002 Share #4 Posted January 22, 2002 It was written by Walter Fath from the Sydney Z-Car Club. I obtained a copy from him August 1998, before it was publicly available & it is my understanding that it's on the money as far as accuracy is concerned.Bear in mind that you can select invalid combinations (KA24E pistons, L20A rods & L24 block for example) & get very interesting results. Even when using 'wrong' selections, you can still use them as a baseline for pin height, rod length, etc.I expect Walter is still on the IZCC mailing list, but it's been a while since I've heard from him.BenAdelaide,South Australia Link to comment Share on other sites More sharing options...
Bruce Woolmore Posted September 14, 2003 Share #5 Posted September 14, 2003 this is a great little tool - I'm looking at doing a rebuild, and was impressed to find so much data pulled together in on spot- agree with a previous comment that another couple of parameters for head and block cuts would make it PERFECT!

hf240z Posted October 30, 2003 Share #6 Posted October 30, 2003 Originally posted by Mike Here is a very cool L6 engine calculator. this is a very good program, the programmer must be very good. hopefully whoever the person is, will modify it a little bit to show if a certain combination is not possible. so a less knowledgeable car enthusiast like me will be warned. totally it is a very neat program.from this program i saw a good combination:an F54(L28) flat top using L24 rods and 2 mmm gasket gives a 10.19:1 compression. can an L24 rods be use on an L28 block without modification? can a 10.19:1 compression use a regular pumped gas without pinging?

nixcars Posted October 30, 2003 Share #7 Posted October 30, 2003 hf240z,This combo won't work because the pistons will be above the block @ TDC by 2.73mm. If you use the L24 crank the deck height will be right but capacity drops back to a 2.6 litre.Always check the deck height when using this calculator, you don't want to be too high or too low with piston deck height.I just ripped open an L28 with flat tops, P90 head & L24 crank that someone had put together some time ago. Now even if this combo engine had a turbo hanging off the side of it, the compression @ 6.6:1 would still be a little low. Nick. Link to comment Share on other sites More sharing options...
Brett240 Posted October 30, 2003 Share #8 Posted October 30, 2003 just how far out of the deck is too far?im 99% sure my pistons clear the deck by 2mm... Link to comment Share on other sites More sharing options...

Hi,what is your combination?are you using a L24 rods on a L28 block, piston, crank,head(p90)? Link to comment Share on other sites More sharing options...

Nick. so is it not possible too if i use a domed piston on an L28 block to increase the compression? Link to comment Share on other sites More sharing options...
Brett240 Posted October 31, 2003 Share #11 Posted October 31, 2003 its an L28 crank with L 14 rods and KA24e pistons with a P90 head, combustion chamber 46cc. problem is the block has been decked so putting those specs in the engine calculator wont be accurate. i know for sure that my pistons clear the block im just not sure how much(from memory 2mm is what it was) this was visible when we rebuilt the engine.
