Hey ppls. After a fair few kilometers I have only good things to say about them. I never used to be able to launch with anything more than 2500 rpm with a clutch dump and be left with anything else but wheel spin. Also, my previous tyres would break traction in first almost as soon as I made decent boost. Yes, my old tyres were crappy. The new Hankooks, well they are great. Although I haven't tried any big launches as I haven't been to Calder Park yet, they seem to hook up great. I've tried some reasonable launches at about 3500 with a fairly rough dump and the damn things just bite and off you go. With the clutch out in first, I now don't break traction until at least 5000 rpm, and by that stage, I'm having to grab second anyway, because it's less than a a split second after that I'm on the rev limiter anyway. Pulling second sees as very breif chirp and then traction all the way. Cornering, well it turns corners pretty well on the street. I haven't got right up it yet, as I haven't been on any twisties or a race track yet, but on my normal streets it's all good. All in all, I can't fault them. Maybe I might even have more luck at the next DECA day with them!! BASS OUT

Apparently I didn't post this picture in this thread, only in my WTB thread. This is the picture I was talking about. The pics above are Big Carls pics.

Discopotato03 Hey dude, those aren't my pics, they are Bigcarls. I just posted them for him. I'm not sure of the turbo or specs. Unless you are talking about the picture of the whole turbo including compressor cover, bearing cartridge, exhaust housing and dump pipe. If you are, I'm only buying it for the exhaust housing, hence it will be machined for the high flow anyway. I don't know heaps about turbos, so if you have some more suggestions about exhuast housings for a highflow, let us know, as it seems some really really good gains are possible just from freeing up the exhuast flow. All help appreciated. BASS OUT

Supply is proving to be a biatch for the VG30DET turbos.

Cool. I figure, it's only a tiny image, I'll see if the bank will allow me to transfer $0.30 to your account!!

Where's the photos of Deca? :innocent:

Here they are.

bigcarl You just need to make the files less than 105 kB, use photoshop or something to reduce their actual size. Then use advanced reply button, and "Manage Attachments" Browse to the pictures, press upload once all the pics are found, wait for the upload to finish, then press submit. Or, Cheers PETE

Here is what we are looking for

Yep, Thanks Joel. You rock.

Yeah, I'm going to put in either some 550s or 720s but I'm just curios about how all the calcs work.

I now know they are rare, that's why I spent 4 hours last night scouring the America sites and wreckers and sending heaps of e-mails and trying to call a few people as well. I have a couple of leads so far, but if I have to go to the states to find them, I'm scraping the bottom. Cheers Pete PS. I can find plenty of good condition VG30DET turbos, just no buste ones.

Still looking

So it's a little harder than just a straight chart. Boost pressure and the like also comes in. Bugger.

1988 Series 1 VN Commodore Executive. V6, 5 Speed. Base Model, weighed nothing. Was a bloody weapon. I did Extractors, Custom Cold Air, Splitfire Plugs (!!!) LSD, Clutch and Suspension, Tyres etc. It's the car I learnt to drift in. It was crazy fun in the wet and sometimes dry. Learnt a lot of things about car control in that thing. Great fun.

Steve. Using that calculator, I use the following figures Desired Horsepower = 422 Number of Injectors = 6 Brake Specific = 0.65 Max Injector Duty = 0.90 System Fuel Pressure = 40 psi I get 557 cc per minute for like 200 rwkW (460 hp at fly)...... Is this right, doesn't sound it. Please explain where I'm going wrong.

When you are measuring pressure and injector sizes, what pressure should I use to calculate?

Have a look at the link, tell me where I'm going wrong, because it did sound a little strange. What is the Standard Fuel rail pressure of a Skyline, and what is a resonable pressure for raising too to keep safe on all types of injectors?

Cool. I will do. 550 cc injectors, is that rated at 550cc per minute/hour what? 550 horsepower I got 8cc per minute. is that about right? makes 480 cc per hour.

Hey guys. I'm looking at new injectors soon and I had a hunt for a bit of a power/injector sizes thread but couldn't find one. I'm not exactly sure how to do the workings out so I thought I might ask somebody to put together a little table. Criteria: powers of say 200, 220, 240, 260, 280, 300, and so on up to say 500 rwkW Injector sizes to suit. I guess you could have the graph in both stock fuel pressure and a resonably raised fuel raril pressure. Injector duty should not exceed 90% for safety. So, who can do the math? BASS OUT

I thought that it wasn't done much because you had to remove the VVT solenoid to do it, thus loosing the effect of the VVT. Higher grunt down low and up high. This wheel makes it possible to try the adjustment without removing the VVT system.

I'n some country towns it's illegal to park with the FRONT IN. They make you reverse park as a law. Fines if you dont. Go Figure

I guess you could use the turbo shaft as a rotor, and either pump power to it to make it spin, or suck power from it when it's making boost to charge the battery..... Maybe.

Anybody trying this cm adjustment want to try the inlet cam adjustment as well? I've got some adjustment rings which you can try. PM me for details.

Has anybody found me an exhaust housing yet?
