Joel,

I'd rather have something that's quick 0-100km/h..... 100-200km/h.....& 200km/h-0 :P No good being quick to 100 but nothing left after that.

I had an interesting dream the other night...... I was side by side with a 280+rwkw Commodore doing 80-90, we both accelerated & I didn't see tail lights x2.

With very grippy tyres (i.e. RE540's - D01J's) 250+rwkw can be used to full effect on the street (once heated) although very grippy tyres can be a tad costly for daily use.

Back to the topic......

A STOCK GTS25t using ELF Turbomax (+ advanced timing) & running slicks would NOT get into the low 13's. Of course it depends on your definition of stock? I take stock as meaning factory standard, no modified parts AT ALL apart from the slicks. You can advance the timing as your not replacing anything but that's about it. High 13’s but not low!

Matt - That Commodore, Have you heard Jaffa is having some work done to the VX?

280rwkw would be needed to sit level with the 33. :P

All depends on the Budget. :)

0-100 or should I say 0-160 is fairly decent with a 200rwkw R32.

That will do me. :D

As sub zero have claimed they ran a 12.8 with slicks advanced timing elf and exhuast.

So your telling me an exhaust will give you 1 full second in the 1/4 ??

If an exhaust system is restrictive enough a 1 second improvement is very possible. Ask any of the SA guys @ a recent Tilbrook dyno day. SPOOLIN's modified GTS25t made 219rwkw & then after replacement of the *very* restrictive cat & cat back section followed up with 282rwkw. A gain of 63rwkw is more than enough to reduce a 1/4 time by a full second.

Bottom line is...... until someone goes out & runs 13.3 or less (what I consider low 13's) in a factory standard GTS25t using only slicks, high octane fuel & advanced timing then I'm not convinced.

Maybe my last comment will gee someone up to prove me wrong :D If so good on 'em.

I can't believe a 12.8 from ~120rwkw in a 1400kg car.

Then again that bloke with the LJ type torana was making around 120rwkw and that weighs in at 1300kg's, He ran some where in the 12's with a really hard launch.

Joel,

The LJ only ran that quick as it was geared (diff & box) for 0-400m only! It was/is flat out doing much over 185km/h. Your car would manage a 12.8 if you set the gearing up to suit 0-400m, in fact seeing as you like 0-160km/h & off the lights stuff why don't you? :D

Yeah I knew Jaffa was having H/C done a while back. Jaffa's LS1 suffered from the dreaded oil consumption :D So why not go for it in the rebuild. The 280+rwkw Commodore I dreamt about has H/C too (+ a 300kw eng to start with) I also dreamt about another successful 80km/h run vs. a 240+rwkw Commie Ute.

260rwkw 1500kg (car with driver)

300rwkw 1700kg (ditto)

I would've thought the above would be closely matched. I could be way off though?

I remember reading somewhere a kg removed is worth more than a hp gained.

I sure hope so to ken doll :D i to belive 13.3 or less is a low 13, subzero have there is hope..

ermmmmm H/C?

ahh Also Remember I do like those Rolling runs Matt. :)

LOL.. Do you tell your Wife about these dreams?

Or does she wake you up and tell you to stop throwing your legs and arms around from changing gears? :D

H/C = Heads & Cam package

:lol: She hears all about the dreams I have (not that she's all that interested) Naa she doesn't cop any stray feet or hands, the roll cage & harnesses keep the limbs on my side of the bed :D

:lol: They must've got their wires crossed dude. It should've been, "Fabio..... the most beautiful man in the world" :)

Who do you know in the RAAF that knows me?

Yer but look at the tyres. And ask what RPM he launched at.

I run those cheapo Simex tyres and they grip so damn wheel where I find it really hard to spin second up out of a corner and first gear doesn't spin on launches.

Bridgestone B530's, older style Donuts, Baraum & Goodyear F1's all would do the above & all with the same width 225 50' 16.

Ahh Rob (or Roo) I should've guessed! His RX7 is getting some serious HP these days! (big turbo & all) Xtra grunt so he can get himself in trouble with the law "again" :P

REV's 13.4 is an awesome time! I know REV had his new S-AFC II fitted, be interesting to know if he'd tweaked the mixtures @ all?

Goes to show just how tough it would be to crack a low 13 with nothing more than slicks, high octane juice & a bit of timing advance. The biggest restriction would be the factory exhaust system. I still think low 13's in a standard GTS25t (with blah blah...) is very unlikely, but maaaaaaaybe possible?

    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
