Hehehehe...

I'm afraid it isn't that simple Linus... As the late Ayrton Senna once said,

"It's easy to drive a slow car fast, but difficult to drive a fast car fast".

What this means is that it's easy to extract near-maximum potential out of a slow car (fast lap times, fast ETs, etc), but it's much much harder to drive a fast car to it's full potential. I guess you'll find this out when you start making proper horsepower out of your s15 :)

The RotorMaster RX7 that we saw run a 7.8 second pass (or something like that) was amazing yes? How do you think it would go with Street tyres? I'd predict a 30.5 @ 172 mph... When you go over a certain horsepower level, there's no point in running with street tyres (well, not 18" street tyres anyway, perhaps 15" Nitto NT-555Rs would be okay), you need slicks to put the power to the ground.

I've spoken to a lot of people who are very experienced drag racers, and expressed my disappointment at the times and they all laughed at me when I told them what tyres I was using... Basically the unanimous opinion was I was kidding myself if I expected to set a fast ET with those tyres. Fast Terminal Speed, yes, but Fast ET? No way.

So I'm going to have to put the slicks on to put the power to the ground, and run the fast ET that everyone judges the car on... I now know how Mario feels when people won't accept a car unless it's run a fast time down the 1/4 Mile... Albeit to a slightly lesser extent :)

You're 110% correct there :)

I just installed a NISMO triple plate clutch in, and I guess it has moved the "weak point" of the drivetrain to the driveshafts...

What's going to happen after I put billet driveshafts in? The gearbox will most probably go BOOOOM tinkle tinkle tinkle :)

As Troy said yesterday at Eastern Creek,

"Terminal Speed is to see what the car can do... ET is for those who want to spend another $20,000 actually doing it"

:bahaha: :bahaha: :bahaha: :bahaha: :bahaha:

well i prefer ur earlier intention of racing ur car on street tyres because that's where u'll spend most of ur time driving. since u mentioned Ayton Senna, i'd like to draw ur attention to another famous quote:

'it doesn't matter if you win by an inch or a car length, winning is winning' :) hahhaahah

Driving yes. Racing no.

Yes, well obviously I've found out that my combination of 18" rims, DMS coilovers and Triple Plate clutch is quite useless for launches on street tyres... Too much power.

But the DMS coilovers, 17" D01Js and Triple Plate are *EXCELLENT* for track work, which is great, because that's what I prefer by FAR... I'm only doing drags for a side activity because it's just another avenue of motorsport that I enjoy...

"Winning is winning"? On the drag strip, unless you're racing a mate, the only person you're racing against is yourself... So I guess I won AND lost? I don't street race, so that quote was quite irrelevant methinks...

No... It was a friendly squirt for 100m between friends whilst driving to get food.

You haven't said one positive or encouraging thing in this thread. All you are trying to do is bring me down.

Thanks for your input, but I don't need it.

hahahahaa....bring it on!!! man u guys take it too serious...i've been whipped by a number of cars.....u win some u lose some..

im not touching VISHES, i've already had my ass returned back on a platter by him, i'll only do rolling starts from now on

I'll have to give VISHES that much.... I remmeber my first encounter with him at the wollongong cruise..... I was looking over my right shoulder and the GTS-T was no where to be seen

....... look over my left shoulder.... "WTF is that S15 still doing there?"

    • Thanks for that, I'll check it all out. I can always do the brakes last anyway if its a problem.  The 16's are super cool, if they do fit I'll cruise around with them for a bit.  
    • Well, that's kinda the point. The calipers might interfere with the inside of the barrels 16" rims are only about 14" inside the barrels, which is ~350mm, and 334mm rotors only leave about 8mm outboard for the caliper before you get to 350, And.... that;s not gunna be enough. If the rims have a larger ID than that, you might sneak it in. I'd be putting a measuring stick inside the wheel and eyeballing the extra required for the caliper outboard of the rotor before committing to bolting it all on.
    • OK, so again it has been a bit of a break but it was around researching what had been done since I didn't have access to Neil's records and not everything is obvious without pulling stuff apart. Happily the guy who assembled the engine had kept reasonable records, so we now know the final spec is: Bottom end: Standard block and crank Ross 86.5mm forgies, 9:1 compression Spool forged rods Standard main bolts Oil pump Spool billet gears in standard housing Aeroflow extended and baffled sump Head Freshly rebuilt standard head with new 80lb valve springs Mild porting/port match Head oil feed restrictor VCT disabled Tighe 805C reground cams (255 duration, 8.93 lift)  Adjustable cam gears on inlet/exhaust Standard head bolts, gasket not confirmed but assumed MLS External 555cc Nismo injectors Z32 AFM Bosch 023 Intank fuel pump Garret 2871 (factory housings and manifold) Hypertune FFP plenum with standard throttle   Time to book in a trip to Unigroup
    • I forgot about my shiny new plates!
    • Well, apparently they do fit, however this wont be a problem if not because the car will be stationary while i do the suspension work. I was just going to use the 16's to roll the old girl around if I needed to. I just need to get the E90 back on the road first. Yes! I'm a believer! 🙌 So, I contacted them because the site kinda sucks and I was really confused about what I'd need. They put together a package for me and because I was spraying all the seat surfaces and not doing spot fixes I decided not to send them a headrest to colour match, I just used their colour on file (and it was spot on).  I got some heavy duty cleaner, 1L of colour, a small bottle of dye hardener and a small bottle of the dye top coat. I also got a spray gun as I needed a larger nozzle than the gun I had and it was only $40 extra. From memory the total was ~$450 ish. Its not cheap but the result is awesome. They did add repair bits and pieces to the quote originally and the cost came down significantly when I said I didn't need any repair products. I did it over a weekend. The only issues I had were my own; I forgot to mix the hardener into the dye two coats but I had enough dye for 2 more coats with the hardener. I also just used up all the dye because why not and i rushed the last coat which gave me some runs. Thankfully the runs are under the headrests. The gun pattern wasn't great, very round and would have been better if it was a line. It made it a little tricky to get consistent coverage and I think having done the extra coats probably helped conceal any coverage issues. I contacted them again a few months later so I could get our X5 done (who the f**k thought white leather was a good idea for a family car?!) and they said they had some training to do in Sydney and I could get a reduced rate on the leather fix in the X5 if I let them demo their product on our car. So I agreed. When I took Bec in the E39 to pick it up, I showed them the job I'd done in my car and they were all (students included) really impressed. Note that they said the runs I created could be fixed easily at the time with a brush or an air compressor gun. So, now with the two cars done I can absolutely recommend Colourlock.  I'll take pics of both interiors and create a new thread.
