Saying 200-220rwkw with decent tyres will get a 12sec is kind of pushing it...Considering both Al and berin were running slicks and 250+rwkw and were managing high 12's from memory...
spot on.

If i was to remove sway-bars, strut braces, and revamp my suspenion set-up, i think there would be a very low 12.

Yeah, and thats still with full slicks and 250+, so 200-220rwkw and 'decent tyres' isn't going to get an easy 12....i'm sure its do-able, but not without some skill

howd you do that with the stock injectors mick ??

Hey Justin. Just changed to a 040 and used a nismo fuel reg. Dont see more than 90% duty cycle.

Having said that you still have to let the car warm up because as SK has mentioned in the past about

fuel enrichment. It wasn't at full temp the other morning and gave it a squirt and saw the engine light

flicker, so i backed of straight away. Checked the hand controller and it had hit 100%. So about 10 mins

later when it was at full temp i tried the same thing again and didn't go over 90%. So in my case i think

i'll let the car (as i should anyway) get to full temp before ringing it's neck. :(

Set your car up and it's easy to run 12's with 200rwkw odd, hell my old bunky was capable at only 170rwkw odd (and it wasn't well setup really).

One method is to throw power at it and nothing else. This is lots of fun even though you don't get the most out of the car from a time perspective. It requires progressively more skill as the power goes up as the car becomes harder to control. Remember this is lots of fun :( But the driver skill becomes more of an issue to stay off the barrier. This is the case with big power cars that teeter on the line of having a setup to cope with the power. And all the fun of the fair for drag GTR owners who are trying to stop the car from kissing the concrete.

The other method is to set the car up better in terms of suspension and things to make the most of the power you have. The interesting thing is you then don't need as much driver skill. The skill comes back in when you play bracket racing and you are trying to get the timing right.

Overall a well setup car with 200rwkw is going to romp a 12 in consistantly. With simple instruction a new driver can step in and do the same. Thats a good sign you have it right.

i dont think so.

My car weighs in a smidge over 1400kg. 220rwkw, 12.9 @ 109 with 225 Simex

Now given my rear end isnt the same design as the R33, so i have less traction to boot. :(

And you cant use Berin/Al as examples as it was thier first time out there. Your not going to run the best times the first session out there on sticky tyres

Check the results that people like Robo's have achieved etc etc.

Its easily possible.

Last night at WSID I saw 4 R33 skylines running shocking times... with exhaust + FMIC from what i saw were in the mid 14's! I even spoke to some of the guys and they blamed poor traction but didn’t seem to be the case from the stands, i could be wrong... the only half decent SII R33 ran a 13.0.. when i approached the car at the pits, i saw a FMIC, Fuel Reg, Splitfires, MBC and exhaust... the turner claimed it also had a high flow turbo and PFC tuned and also claimed a unreasonable 290rw/kw.. which i thought was bit farfetched due to having a highflow... could i be wrong? I'd be pretty pissed if a 13.0 was the best time i could get with 290rw/kw...

Cheers

I think people need to move past 'driver skill' and take a good hard look at how poor the setup they run is for drag racing. The 'driver skill' argument is used by people the world over when they don't want to see something wrong with the car setup. Like I said though wheel spin can be fun too, and drag racing is just plain good fun no matter what.

If you can't run a 12 with 220rwkw in an r33 there is something wrong with the setup/driver.

JZZ30 soarer, 226rwkw, auto, street tyres, 12.9@113, 2.160ft. Seeing as a soarer weighs about 200kg or so more than an r33 and a 2.1 60ft isn't even that great from the soarer it should be pretty easy for a skyline.

I have already admitted my car's suspension set-up is totally wrong for drag racing, but i still like to get out there once in a blue moon, just for fun.

Ash: Your R31 is actually better suited for drag, as the rear wheels do not camber in on launches, thus has more rubber on the road, thus has better traction :/

I agree with Ash, Pm 'robo's' about his setup, its pumping out 231rwkw and he has managed a 12.1 @ 116mph on stuffed semi slicks..

Not bad at all, his car had loads of midrange, he also got a 12.5 with a smaller turbo setup and only 220rwkw..

Totally diferent car and suspension set-up

umm not really i mean some ppl have the idea you launch at 8000rpm then wonder why they get a shit launch due to wheel spin...theres a lot to do with it.

No my friend theres not a lot. Simple instruction is all thats needed and a bit of practice. The guys that launch at 8,000rpm and have too much wheel spin, like most, have never bothered to get advice or even experiment. Thats got nothing to do with driver skill but, rather just plain simple process applied to a small amount of practice.

Thats really quite an encouraging thing because it's got nothing to do with your gene's.

Al,

Robo's car has IRS like yours, so basically the suspension setup is the same.

To help you get more traction you can't look past what is one of the most overlooked and yet most effective mods : PINEAPPLES ! --- these little $100 beauties will give you a big improvement in grip, so slap them on if you haven't already.

Drag racing is always lots of fun even when you don't get the greatest times. Having a 'fun' attitude to it usually sees you do better times since you aren't all uptight about it. :)

      I know mentally you're set on the ATS clutch but honestly I'm a big fan of the Nismo Super Coppermix Twin. It's much cheaper and in some ways I think it's a better design for a street/circuit car.

      Just checked in first post and you should be able to bring it home November this year, right? I'm amazed you made it through four years of this. As hard as it feels now the rest will go by in a breeze in hindsight, I'm sure.

      Realized I haven't been back here in a while. Still here, still alive, still waiting for the car.  I went back again the only time last year from Oct-Nov for R's Meeting and drove it around some more, including a few laps on Fuji Speedway(in the wet, sadly). The car still feels good, but have a couple small things to address. I've been getting more parts but have slowed down still, and most of the bigger purchases are now out of the way. I find myself getting impatient more and more when it comes to getting started on this project; it's quite hard for me not being able to really dive in and start making this car my own because it's halfway across the world. At times it doesn't even really feel like I own one of these. Haven't really been motivated or had the desire to document the last trip on here or social media for, well, reasons... but here's some pics...it's also still alive and well as you can see: I've narrowed down to the last large part purchases(anything over $2k) before the engine build to be: 1) Ohlins Road & Tracks 2) ATS Twin Carbon clutch 3) Endless BBK with some custom options and 4) Kansai Service carbon driveshaft I don't think the budget exists for all of these this year, but I'll try for one or two items I think. Though, every time I look at my spreadsheet I sigh, shake my head, and get depressed just that little bit more.  'til later.

      It's a stunning location!  I've been to NZ twice but haven't made it to the North Island yet.  Definitely on the cards but the South Island is hard to tear yourself away from too... Looking forward to see what you can wring out of it once you can get it to hold together!  Be awesome to get a low 11 or even sneaking into the high 10's pass out of it.  That's a bloody quick car that most people will never experience in their life.  Enjoy!

      Nominally yes but I’m not really at that stage yet. Outsourcing to Japan is also a relatively good deal at the moment because their currency has devalued much more against the USD.  You would assume this but a lot has changed from the pandemic. Mechanics are in short supply and demand for fixing old cars has gone up from the cost of new cars. 250-300 USD/hr is not an unusual shop labor rate in California and you’re paying that regardless of whether the guy is competent or not. Coworkers have been quoted 3000 USD for a water pump and thermostat at a dealer on an N54. Oil changes went from ~75 USD to 150 on fairly normal cars like Civics. The cost of the oil and filter hasn’t even kept up with inflation.
