Pawley, got standard dump pipes, but HKS front pipe, I would assume front pipes would make a noticeable difference, may push your terminal speed to about 114mph???

Don't quote me on that though.....

Okay lads, I'm just concluding a new DVD being released through the same outlets as High Octane, and HPI in May called 'Car Crazy', and in it is a feature story about drag racing, including a story about tuning a near stock GTR to run in the 11s. In the first part of the story the car consistantly runs in the low 12s with 220 - 230kW at all four wheels as measured on C&Vs dyno. The 60ft times were between 1.7 and 1.8 seconds. At this stage the mods included:

HKS dump pipes and full exhaust

HKS cam gears

Japanese ECU (non-tunable)

HKS pod filters

1-bar of boost

Nismo twin plate clutch

From here the car is being tweaked to achieve a high 11 second pass while retaining the stock turbos, fuel system and engine. I'll be using unleaded ANDRA approved 105 octane fuel, higher boost pressure, a different (albeit cheap) ECU upgrade, suspension tuning, and a mild wieght reduction (spare wheel/jack, stereo system).

Should be running the 11 second configuration during a private filming session at WSID next week.

My friend ran 11.4 at 121mph, on 1.2 bar, advanced timing ,extra injector triggered by a hobb's switch and a cheap water injection setup. I then got him some R34 turbo's and it went 11.3 at 124mph!, power?, never seen a dyno! It's an early R32GTR., Back in the early day's when Munro and Willalll were only running low 11's with big dollar setup's.

Well doen Jack, so damn close to that 11sec pass.

You gotta nail those 60 footers in the 1.7s mate. :)

Thanx Emre, you probably know how it feels, been there before haven't ya?

Yeah my 60 ft times have been around the 1.85s, but that's with 265/35/18 hankooks, might have to get the original 17s with sticky rubber and I'll be in the 11s for sure....

What am I doing wrong...

I have 240 kw at all 4 and get a reaction time of 0.46 and a 60 ft of 1.7 (average) and a terminal speed of 108mph (average) my best to date is 12.365 but average about 12.50...by the way I tried my hand at a bracket meet last night and won $100 and a trophy...

so why are you all faster...i also have steel wheels and 1.3 bar

ricknismo, your 60ft times are superb, but looks like your midrange is suffering....

108mph is definetly not good for a flat 12, considering I'm getting 114mph....

With steel wheels usually u get more lag, so maybe that's your problem???

Don't quote me on that though.....

You got a decent clutch???

It doesn't work out with the averages mate. What is your best 2-3 mph so far...?

If you are not pulling 114mph, you only have a dyno printout of 240kw.

      Rusty roof repair

      Nah that is not actually a lot. Just painting my GTR frontend and the little bits to make sideskirts/nismo flare pieces work correctly/fit on the sedan/mount up correctly came to about $7000. Is it a lot? Sure. None of this is economical. Economy would be shelling the car and buying a 2010 Corolla to commute in. The perspective of all of this is different.

      I don't see any issues here. I've been saying all along this is a big job, the price reflects that.  When the car comes back perfect I'm sure it will feel like money well spent.

      Remember, take original quote. Double it. Then add a bit more. It's how any project goes.

      Rusty roof repair

      By PranK · Posted

      So, I started this repair and got as far as "fixing" the holes with some fibreglass. God all those years working on boats came back quickly. I decided I'd reach out to some rust guys just to see what they would say about it. I came across a guy about 40 mins away and went to see him. He said the windscreen needs to come out, that there might be some more bits around the windscreen and he'd quote them at the time. But his quote was $300 to remove and replace windscreen and $3k for the damage he can see. He said he could respray the roof for $1200 and the bonnet for another $800 (somebody has previously rattle canned it, its horrendous). This is $5300 + any small additional bits. It's a lot, I get that and the name of one of my fave youtube channels 'Not Economically Viable' comes to mind.  I'm not being financially rational, but I've taken him up on the quote. He's opening a new shop in November with more room, so we're waiting for that. I'll leave the currently missing headliner out until then. I'm looking forward to it being fixed and having the paint looking nice again (lots of clear coat issues on the roof too). / flame suit on.
