@FunctionFirst @SaudQureshi Typically, a motor designed with a longer stroke length than cylinder bore diameter (undersquare) will have more torque (especially in diesels), but some drawbacks would be that it wouldn't be as reliable to constantly rev at high since pistons speeds will be faster. Oversquare motors tend to be able to rev higher. Square motors, like the K20 (86mm x 86mm bore & stroke per cylinder) are more "balanced".
I'm no mechanical engineer, but I don't think the ratio of 1hp : 1lb/ft torque equals a motor with balanced power.
@Gerben aka Suburuuh My theory is the track is pretty safe by design. It seems like there is are lots of soft barriers and good runoff space where it counts near the end of the faster sections. Also, the 4-point harness will be plenty safe in a frontal collision and won't offer spinal compression given that the seat is FIA-certified or as strong as an FIA-certified seat.
@JDMized I'm pretty sure 5zigen knows what they are doing if they set the FF record at Tsukuba. I'm also sure that since that is the car they work on physically and have been in and out of it, they have a better idea than you do.
@JDMized @speedhunters_dino Dino be trollin. Please keep sharing your knowledge, JDMized.
@speedhunters_dino @pwhyze @JDMized Shhh... Look here: FIA Appendix J, Article 253:Page 3/20, Article 6.2 http://argent.fia.com/web/fia-public.nsf/1B58641F5BF3AF4AC1257A8A0038BF8D/$FILE/253%20(12-13)-(28.09.2012).pdf
No Renault R26R?
When properly sorted, driven well, and placed in competition in the right class, FWD doesn't really have much of a disadvantage. I drive a FWD car and enjoy it, but I know it's not ideal in many performance driving situations. At least it's easier and more forgiving to drive. Just can't really adjust rotation and rear slip angle like you can with RWD. BTW, Renault makes some of the best-performing FWD cars besides Honda. I wish they could sell their cars in the U.S.
@varilight @somebodysb2 Not really. It's because of a few reasons. In low-power classes, there's not much advantage RWD has over FWD. Also, the drivers of the RWD BMW WTCC cars can't hop curbs to lift the inside drive wheel from the ground then land while still planted in the throttle otherwise they risk breaking the half shaft. There's also a slight but noticeable weight disadvantage of the BMW 3-series WTCC chassis. They just can't reduce any more weight from the chassis. The FWD cars take better advantage of lifting the inside drive wheel over curbs to corner faster without putting enough stress to break driveshafts.
Ooh you've got a point there. Schroth does mention in their instructions that the tail straps should be crossed if not fixed to a location within 200mm of the shoulder point, or something along those lines.
They won't significantly weaken if you don't bend them one way, then back the other way. That would stretch and weaken the metal. In the install, they intend for them to be bent in one direction once into the angle you need. In my opinion, these brackets would be just as sketchy as using factory anchor points, which are just holes with threads with a high grade bolt installed, but factory anchors are designed to withstand approximately (if I can recall) hundreds if not thousands of pounds of force over several seconds.
Schroth uses the same bendy brackets in their harness systems mounted the same way as these Takata harnesses. They have DOT and TÜV safety approval and have been through crash testing.
What do any of you safety experts know about crash safety and design of harnesses? I'm not sure what approving safety organizations Takata has to go through for this 4-point harness, but I know Schroth has a very similar system that is mounted the same way and approved by the likes of the TÜV and DOT. They've gone through crash testing with all hardware and components mounted as they instruct their customers to do. I recently got flak about my Schroth harnesses on a forum I frequent. I'd say it's a good idea to install these if they've been tested thoroughly and have been deemed to be as safe as the factory belt system from proper safety organizations. The webbing in the factory belts do weaken over time, and installing proper harnesses may even be safer.
@jimmyhoffa Schroth also has their Rallye 4 and Quick-Fit 4-point harnesses mount to the rear seat belt anchor points. They're also approved by the TÜV and DOT. I think they are the only harness to have DOT approval. I know even the FIA approves mounting a harness up to a -45º angle from the shoulder, but +/-10º is what they recommend.Dino also stated that he's looking into a harness bar to reduce the angle of the harness from the shoulder. He obviously posted that statement because he knew people would tell him to mount them higher.If you don't want the look of the harnesses in your car but still want to be held firmly in your seat using the stock 3-point belt, look into the CG-Lock.
Why should there be any "rules" to engine swaps? A motor is just a motor, albeit a different one. There's always something to appreciate in an engine swap, even if you're not the one who owns and drives the car. If the owner wanted a particular swap for whatever reason, then it's justified to him, and not you.
Camel Toeing... Heh heh
@ToyotaSupraMan I agree. They would make more money from renting it out for private testing than from the tourist driving. When somebody would wreck on track badly enough, they would shut the track down temporarily to get the mess cleaned up. This could last anywhere between one hour to at least half the day. Sure, they charge the person who wrecked a heavy fine to make up for lost business, but it doesn't make up for it completely.The track fees have gone up every year from when I was first there 3 years ago. It used to be only 20€ per lap, and last year, it was raised to 26€ per lap. The price increase didn't keep very many drivers away, though.
Hey, a buddy of mine gave me one of those Hakosuka GT-R's. It's still in the box.
My dream!
Sweet! I was stationed in Germany and lived in Bitburg up until a few months ago! I miss that place.
I like TRD's simple tuning package. I think a lot of people get the wrong idea about the new 86. I don't expect it to be fast, just like I don't expect a Miata to be fast. It's all about having a lot of fun in a very well-balanced car.
