I'm building an 88 EF with a K24. I'm concerned about the low. I'm excited to see what the CRX looks like when you're done. I'm curios to see how far back you can get the motor. Also, I designed bolt in custom mounts to adapt a tucked radiator without having to drill the core support. Should fit the CRX if you don't already have a clean solution. I've been meaning to make a repository. any who, great video.
Again always topics of interest for everyone. Regarding suspension I have just had similar issues . Whilst designing double wishbone/ pushrod suspension for our e36 GTR . I started around the steering rack inner pivot points and used this for the centre line of my bottom arms . Then keeping the bottom arms and rack horizontal at ride height I designed the upright and steering arm brackets . After setting the wheel at aprox 4 deg neg camber / 7 deg castor I then designed my top arm . Mounting that horizontal and to give no camber gain . With that I can then have multiple locations for the top arm to induce camber gain and some adjustment of roll centre. With spacing the arms as far apart as possible ( vertically) it gives the suspension more rigidity . Travel is restricted to aprox 15-20 mm droop on the front and 50mm under compression . Went for pushrod suspension as droop / ride height / spring pre load are simpler to set . Ended up moving the engine 300mm further back for rack / bonnet clearance and weight distribution . Drew everything up in cad and had mock ups laser cut . Have to see if it goes round corners now !!! 😵💫 Nice to see your flywheel, is it all alloy / 1 piece including the ring gear ?
YT had a bit of a spaz and put the wrong comment (I deleted now) on here for you sorry. It mixes them up in the backend sometimes but I have just learnt what to look for with it happening to this post now! It sounds like you have given yourself the best chance for success when it comes to going around corners as fast as you anticipate! It's a chromoly unit that is 1 piece, including the ring gear 😎 - Taz.
@@hpa101 ha ha no worries I get spazed out myself anyway. Yeah a bit of testing and geometry mods should eradicate any handling issues that the 70’s yank tanks were renowned for 😵💫. It looked like an all alloy flywheel from the content, that was the main reason for my question Taz . That would have been one option for me and just get one water Jet cut and balanced. Don’t like the idea of an alloy one falling to bits and having an argument with the bell housing and my feet . !! Our s58 had the 8 speed box but I’m considering using the flex plate and then making an alloy boss for the 7 1/4 inch clutch to bolt too . Super light and cost effective. Cheers for the reply 👍
Would there be a benefit of using the K24 block even for a 2.0L build (suppose an 86mm diameter inner liner or a shorter stroke billet crank) considering that the taller dek height would allow for a better rod ratio? I suppose there is a weight increase of the rods themselves in this case to consider.
I've wondered about the same thing myself. The larger bore and short stoke, with longer rods, has many potential advantages - about the only negative I can think of, from a power standpoint, is it may be harder maximising the compression ratio. As you say, the rods will be heavier, as may the pistons, but they would be travelling a shorter distance so that will be partially compensated for, the intertial loading around TDC will be significantly reduced so potentially allowing more rpm and dwell at BTD would be reduced. There's a Greek chap with a VERY extensively modified N/A Ford Cosworth 2 litre turning close to 12k rpm and putting out over 400hp - it sounds MENTAL! ua-cam.com/video/G3snibHTZpw/v-deo.html Since been repowered with an M5 engine of unknown spec'.
You guys rock! I'm an avid listener, probably have listened to all podcast over 10 times. I get about 5 hrs of hpa in a day between that and the courses I've purchased. (Professional Big Rig Driver.) Lot of time on my hands lol. I've heard recently about the giveaways in the latest few. I can't seem to find where to navigate on the site. Could you guide me in the right direction? Thanks Taz
That's commitment mate! Glad to be doing something that you enjoy and thanks for the support 😎 Bookmark this link: hpcdmy.co/giveaway It refreshes to the latest giveaway no matter what it is. Markku here is trying hard to keep them rolling and I think already has another 5 or so lined up after this current B-G Racing one. They will always be free to enter too, so never any harm having a crack at them. Best of luck and thanks for listening/watching Josh! 🤘 - Taz.
We have plans for webinars around that, for MoTeC too. We haven't had a chance to lay out a proper game plan yet as we're still clearing up a few previous goals already in the works first. Any specific questions about it all? - Taz.
You make the adjustments to suit. In this case given an aftermarket gearbox is going in it is 'easier' as you need to sort that out no matter where the engine is - Taz.
If you actually look at it, it's a standard TILTON 5.5" clutch assembly - you can match the spring rate, leverage ratio, plate number, and friction plate material options to match the engine torque you expect. There are several other manufacturers who can also supply similar clutches - if you have the budget you can even go for a full carbon-carbon assembly in push, or pull, configuration. If you can't find someone to machine a matching lightweight flywheel, TTV in the UK may have something to do the job. however, going to this extreme is 'overboard' for 99% of people's needs, and there may be other options that are much better suited for them.
Sure. If you send me one I can gift wrap it and send it back? Maybe? 😅 This EMtron prize went to a chap called Adam, but you never know next time. It's always a long shot but it's worth a shot right 🍀 - Taz.

Lowering peak piston speed for higher rpm ceiling has negative effects re peak velocity and pulse strength for intake and exhaust.

@@silverwolf4095 Realtive to an NA build though, Yeah? otherwise it's just more inertia under load... I think

Hey guys are you updating the Emtron suite to showcase there new updates eq torque modelling tools and tuning 👍👍
We have plans for webinars around that, for MoTeC too. We haven't had a chance to lay out a proper game plan yet as we're still clearing up a few previous goals already in the works first.
Any specific questions about it all? - Taz.
Cool. Maybe grab a CAN TCU and nock out a 8hp and DCT conversion while your there ✌️
Do I need to run two MTron KV8 controllers if I have a V12 that I want sequential FI and ignition?
Take a look at the KV12 - emtron.world/product/kv12/
Moving the engine back in a Fwd car, how do you deal with the angle the front axles get?
You make the adjustments to suit. In this case given an aftermarket gearbox is going in it is 'easier' as you need to sort that out no matter where the engine is - Taz.
Where is that clutch and flywheel sourced from?
The clutch just came from a local supplier (Cardwells) who we use often as they have good service, and the chromolly flywheel was custom-made - Taz.
If you actually look at it, it's a standard TILTON 5.5" clutch assembly - you can match the spring rate, leverage ratio, plate number, and friction plate material options to match the engine torque you expect.
There are several other manufacturers who can also supply similar clutches - if you have the budget you can even go for a full carbon-carbon assembly in push, or pull, configuration.

however, going to this extreme is 'overboard' for 99% of people's needs, and there may be other options that are much better suited for them.
Mind me asking where the flywheel was made. I need one to suit a K20 also@@hpa101
Can you send me an EMtron KV8 please? Thanks.
Sure. If you send me one I can gift wrap it and send it back? Maybe? 😅
