Finally got off my ass and went to a Street Meet. :yes:

R33 GTST, stock clutch, turbo and suspension, standard bolt on mods, 197kw @ 0.85 Bar

Front 235/45/17 Dunlop FM901s Rear 255/40/17 Potenza GIII @ 35psi, lowered to 33psi at the end

First couple of runs @ 0.7Bar

Run 1 - me:

60' 2.433

ET 14.971 @ 96.37 MPH

Run 2 - my bro

60' 2.733

ET 15.278 @ 97.22 MPH

Was misifiring (needs retune) so boost wound down to 0.65 bar

Run 3 - vijay

60' 2.221

ET 14.892 @ 95.55 MPH

Run 4 - my bro (vs GTShortie)

60' 2.343

ET 14.730 @ 91.19 MPH

Run 5 - vijay (vs GTShortie)

60' 2.107

ET 14.516 @ 95.78 MPH

- It was the first time ever at a drag, let alone competing- never seen the staging process or the 'christmas tree' until we were racing. Our first races we both staged 2nd and wasn't ready for the start. By the end of the night I was staging early and waiting to drop the hammer

- I can't do burnouts. Last one of the nite I tried to step onto the brakes but I think I did it too much

- Shifted too early, around 6500rpm

- Dropping stock clutch does NOTHING for launches. Tried it the 2nd time and tramped badly.

- Retune next month, so I can run on high boost

But it was the best rush! :) Definitely be back there soon...

Anyone got any advice from the results??

1. At a street meet it doesn't matter if you launch immediately after the light turns green or wait a few seconds then go, your ET will be the same (reaction time doesn't matter), so stage up, compose yourself, then go when you're ready.

2. Don't worry too much about the burnout unless you're using soft semislicks.

3. Try lowering your tyre pressure even more, with 255/40/17 i'd be trying to get more sidewall flex by going as low as 20psi, but its a matter of trial and error.

4. What mods exactly do you have? I would have expected 95-97mph from a car making under 150rwkw.

What rpm are you launching at? With 255 rubber on the rear (drop it to about 20-25psi) you would be dropping the revs from around 4000-4500rpm i'd think? If you can nail a 2.0sec 60ft time you will drop close to a second instantly.

Rev it out more before changing, up around 6800-7000rpm somewhere. You may even be able to hold 3rd gear across the line and should be doing up around 100-102mph.

Hi, i've got virtually a stock car running a 3inch exhuast, stock clutch stock boost etc etc, my first time at the drags got me from a 14.6 down to a 14.1 at 97mph.

1st run = 14.53 at 96.4mph

2nd run = 14.32 at 97.15mph

3rd run = 14.11 at 97.7mph

4th run = 14.23 at97.5mph

5th and last was 14.64 at 96.4mph ( stock clutch gave up the ghost and slipped from the get go).

It was a great night and i will be going again now that i've got a new clutch and boost controoler. Can't wait to see what it will run now. PM me when you go and if i can i'll meet you there! Lots of sau ppl go.

      You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.

      R32 gtr transmission strength, billet plate

      By cosline · Posted

      Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik

      Spotted on the street....

      By Rezz · Posted

      Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
