CUL8R Posted January 13, 2022 Share Posted January 13, 2022 Id try getting a quote through Pack Send from Australia, they offer very competitive prices and sharp turn around I brought over a gearbox and had it here within a week Quote Link to comment Share on other sites More sharing options...
Popular Post Roman Posted January 14, 2022 Author Popular Post Share Posted January 14, 2022 Last night at Nightspeed. Suuuper busy, but it was really awesome to see a big crowd at the drags, lots of spectators too. Was a cool atmosphere. So first run, set the hoosiers to around 20psi which is very high, but wanted to start out conservative. Ran a 14.092 @ 100.21 mph with a 2.33 60ft. So first run and I've beaten the Carina by every single metric. What the hell! But so stoked! I was convinced at this point that I'd get a 13 tonight. Second run we dropped the pressures a bit, launch wasnt so good and I ran a 14.1 with a higher 60ft. At this point I figured I'd probably cursed myself saying I'll get a 13. Looking at the logs of both runs, the motor was bogging a bit when I was trying to roll into the throttle and clutch. So third run, set a launch limiter at 5500rpm. Full throttle sitting on line, dump the clutch. And holy fucken shit. No wheel hop no big spinning, just felt like stretching out and releasing a rubber band. It felt so much faster than my first run, I crossed the line realizing it must be a 13. Absolutely fucking stoked beyond belief Get my time slip and was blown away 13.83 @ 99.6 mph with a 2.1 60ft Was in about 5000 out of 100 fizz mode, it was so cool. I didnt get any more runs, because it was incredibly busy and was already 10.30pm or so by the time they started the eliminations. But it's incredible to think that it could still possibly go faster yet. Even just doing that time was incredible. It felt like it could have easily launched another 500rpm or 1000rpm higher and hooked up good. Will be back! 43 6 Quote Link to comment Share on other sites More sharing options...

keltik Posted January 14, 2022 Share Posted January 14, 2022 I went into the cupboard and found a hat just so I could raise it to you sir. So it's as quick as a sr20det Hilux and faster than anything I've taken down meremere 5 1 Quote Link to comment Share on other sites More sharing options...

Any thoughts on tweaking the suspension some more? Also massive congratulations impressive result, thats with full street trim as well yeah? can always lose some more weight Quote Link to comment Share on other sites More sharing options...
Roman Posted January 15, 2022 Author Share Posted January 15, 2022 Thanks. Honestly I dont think it's even at the point where tweaking the suspension more is needed. I only got 3 runs and I dont think I'm too close to dialling it in yet on those tyres. I reckon launch another 500 or 1000rpm higher and my 60ft would drop even more. Not full street trim, I dont normally have the back seats in, but took out the passenger seat this time. 4 Quote Link to comment Share on other sites More sharing options...
xsspeed Posted January 15, 2022 Share Posted January 15, 2022 So good. I feel it in my bones that this wants to keep on revving higher and I want to hear it with big exhaust k thx pls 3 Quote Link to comment Share on other sites More sharing options...
deankdx Posted January 15, 2022 Share Posted January 15, 2022 at this point you'd have to consider sticking the seats back in for a run just to say "it runs a 13 in street trim" other than the slicks. (assuming it can) looking forward to hearing what an exhaust can do.. even if it just sounds better with dorts front and rear Quote Link to comment Share on other sites More sharing options...
kpr Posted January 15, 2022 Share Posted January 15, 2022 I dont recall those tyres dropping trap speed at low pressure. well not significantly anyway. 10psi and 8k launch should get it moving. need to run less in them than if it were a rwd 13.8 is pretty impressive, but should go at least 13.6 i recon 6 1 Quote Link to comment Share on other sites More sharing options...
Popular Post Roman Posted January 15, 2022 Author Popular Post Share Posted January 15, 2022 Yeah, after my second run I had a sinking feeling I had some beginners luck and I wasnt going to dip into a 13. I was praying for like a 13.999999 haha. But then when it hooked up like that I just knew. Man it was awesome. And yeah, my last run was the fastest and I only got 3, so it's potentially not even tapped out as it is. Still just blows my mind that it's even possible for a 1500cc NA setup to do anywhere near that sort of time. Also just like my first time going on a track with semi slicks. It goes to show just how important the right tyre is. See people spending $$$$$$ on their car but then on the wrong tyre for the job. Cheapest way to go fast. Especially when you borrow them from @Stu haha I just had a look through logs from my fast run. Looks like after dumping the clutch the rpm falls to minimum of 4500, which is great as below that is the area I really need to avoid. So I'm 100% keen to go back and try a higher launch rpm. And now super keen to get the exhaust done. 24 1 Quote Link to comment Share on other sites More sharing options...
shrike Posted January 15, 2022 Share Posted January 15, 2022 So exhaust and a 50 wetshot of Nitrous and aim for a 12.9? 2 Quote Link to comment Share on other sites More sharing options...
Roman Posted January 16, 2022 Author Share Posted January 16, 2022 Nah I'm good for the NOS, realistically my rods are probably on a limited life already! Maybe if I fit those stronger rods though... I think with ITB you'd go for a dry shot and control the fuel addition with with the computer, so you just add injector duty when nitrous is on. Use a secondary fuel map that uses bottle pressure vs rpm as the load axes. Use the ECU to trigger the map change and the nitrous solenoid. Keeps the setup a lot simpler and less messy with extra fuel lines and nozzles everywhere. It's a pity nitrous is so expensive though, it's a cheap buy-in but becomes uneconomical very very quickly in NZ. As we cant buy any of the cheap non medical grade nitrous here unfortunately. In America, nitrous refills are incredibly cheap by comparison, as you can buy "car grade" shitty stuff. 2 Quote Link to comment Share on other sites More sharing options...
shrike Posted January 16, 2022 Share Posted January 16, 2022 @Romansounds like you need to get another Prius engine from the wreckers and build the bottom end with beefier rods and some other go fast mods (cleaning up casting marks etc etc) just don't add any speed holes Good point on the Nos dry shot, typically when I've seen/done Nos its always been when injectors are getting close to the limit on 4 cylinder turbo setups (2200cc injectors) in saying that these days dual injectors per cylinder is more common I forget this is N/A sometimes, effectively you've gotten double the factory horsepower which in most cases would be a bar of boost to achieve (general rule of thumb obviously) Didn't realize the cost of it in NZ was that nuts, its about $14 per 500g here (but can get cheaper options if buying in bulk etc) though the states is like $3.5usd a lb or $1.70usd a lb if you buy 60Lb at a time Though I guess if you work it out then at $14 a run its not that cheap as i'd expect you to use a lb per run and $140 per refill of a 10lb bottle isn't cheap Keen to see the exhaust gains tbh Id say what about pre intake C02 cooling but as your running ITB it wouldn't be that easy, dry ice on the intake manifold between runs? :p Still got sound deadening? 1 Quote Link to comment Share on other sites More sharing options...

IMO anything faster than 15 seconds needs a proper drag tyre otherwise you are wasting time with any performance mods if you can't use 100% of it to get down the track I've had a few sets of drag specific tyres even on mid-low 14 second cars and if nothing else it makes the car a lot more consistent which is very important if you want to get anywhere in DYO I've raced the VG on street tyres quite a few times, that doesn't have much power and its auto and even then it's a bit of an unknown if it's going to hook or spin 2 1 Quote Link to comment Share on other sites More sharing options...

The air going into intake different story NOS goes against the whole NA tuning thing imo. may as well just jam a 150 shot on a stock echo - maybe someone should do this 1 2 Quote Link to comment Share on other sites More sharing options...
