Yeah had a bit of problem getting traction for awhile - I didn't let down tyre pressure or anything though so next time I'll make sure I take some slicks or stockies to get a better time :laugh: First time I've taken it down too so gotta work on a perfect launch for limited spin I think!

Oh bugger :) Not even on the octane photos??

Well I am happier now after finding out there was indeed a problem with my car on the night :huh:

I had it tuned Wednesday and drove straight to the drags

It Made 355rwHP @ 18psi from 315rwHP @ 14 psi previous, and it definately felt faster on the 2 squirts I gave it on the way down to the Motorplex, i felt fairly confident it would do an 11.9.

Previously (with 315 @ 14psi) I had ran 3 x 12.6's @ 180kmh

On Wednesday (with supposedly 355 @ 18psi) I ran a 12.4, 12.6 & 12.8 all at 180kmh :)

Turns out somewhere between the tuners and the drags the PFC Boost controller has reverted back to 14psi, or its has a boost leak, as all it boosts to now is .95 bar which would explain why the times were exactly the same.... :laugh:

Goes in Monday to be sorted out.

yeah i saw a few traction issues

mind you, a few people were running like heavy 17 and 18 inch rims with not that much rubber

reducing tyre mass, and increasing sidewall height for the drags is a good idea - firstly reducing sprung mass (less tyre mass = less inertia = quicker of the line) and secondly allowing the rim to 'spin' in the tyre and allowing more grip (sidewall wrinkle on drag cars)

its funny, ive heard convo's between guys in their 'fully sic commodores' complaining that there running shit times, and ive asked them what there setup is. the answer: full stereo system, big 17,18,19 inch heavy chromies, tight coilover suspension systems. HELLOOOO, thats ur problem right there!!!

Haha mine are 19s :) Hence why stockies next time! Comparing the difference will be interesting actually.

do you have stock lsd?

i watch one of your runs and ur backend was all over the place most of the track :laugh: we got the same power and once im into 2ndish traction is everywhere!

aww sorry for missing you out GODTHRILA... I think these are you...lol

Yeah I stayed in the stands most of the night. I had my son and his friend watching the speedway so coudln't leave them....

I came down to the pits but noone parked up :).. lol and I don't think two 7yr olds would of been allowed in the staging lanes.

Yes, after the first pass on slicks and a close call with the wall I was relagated to using street tyres, which didn't make for any fast times, but still a great night.

If someone has footage of the spin then please post it up :(

In a total of 4 passes I spun, shredded my wheel nuts, and blew off my intercooler hose. But it could have been much worse. At least I gave the commentators something to chat about :wave:

Where's my money biatch, you were owned by me all night hehehehe, but congrats when you finally got down the track with a great terminal.

I was Very happy that even on street tyres I ran a very low 12 @ 119mph so I know that 11's are on the cards, maybe hig 10's. We will have to that again paully when you get back. Score 4 - Nil to me (smack that ass)

Everyone,

Thanks for coming down, it was great to see so many liners and we put the trevs to shame with they hard fought 14's lol. It was great to catch up with everyone in a speed format. See everyone there again sometime.

Paully,

Now that I have seen this pic, Im glad that I was past you when it happen as Im sur eyou would have T-boned me, I think we both better think about our tyre set-up next time LOL :happy:

Haha, you were miles gone by the time I ended up like that, but pity there isn't a vid to show the real story :happy:

I will admit your ET's kicked my ass all night. I was however happy with the 125mph terminal speed and 0.007 reaction time. I may well be down in two weeks time to try my luck again :(

Paully,

Hey Paully,

You are going to have to explain how you ended up like that for those of us that weren't there to see it :) haha

Since you have had your car back you have pointed it the wrong way on the cruise, and sideways at teh drags...what's going on? :) maybe you should swap engines with me :)

Jason, Simple story really. Don't run slick tyres with radials on the front, cause there is a high chance you can spin :) Yes, seem's like I'm making a habit of facing the wrong way, which I'm sure won't change when I go to Wanners on Thursday night :)

i got a small vid of the begining of the spin on my camera, daughter thought is was me (to many grey skylines on the night) and and decided to look instead of taking all of the spinout. will post soon

oh really ? u serious hmm well i saw sumone who looked just like him then lol i na white 33 black rims and had plates arhh 33 lol i puled up next to em and said hi and he gunned it looeked like mitch to me unless ... lol

    • You are selling this? I have never bought something from marketplace...i dont know if i trust that enough. And the price is little bit "too" good...

    • It would be well worth deciding where you want to go and what you care about. Reliability of everything in a 34 drops MASSIVELY above the 300kw mark. Keeping everything going great at beyond that value will cost ten times the $. Clutches become shit, gearboxes (and engines/bottom ends) become consumable, traction becomes crap. The good news is looking legalish/actually being legal is slighly under the 300kw mark. I would make the assumption you want to ditch the stock plenum too and want to go a front facing unit of some description due to the cross flow. Do the bends on a return flow hurt? Not really. A couple of bends do make a difference but not nearly as much in a forced induction situation. Add 1psi of boost to overcome it. Nobody has ever gone and done a track session monitoring IAT then done a different session on a different intercooler and monitored IAT to see the difference here. All of the benefits here are likely in the "My engine is a forged consumable that I drive once a year because it needs a rebuild every year which takes 9 months of the year to complete" territory. It would be well worth deciding where you want to go and what you care about with this car.
    • By "reverse flow", do you mean "return flow"? Being the IC having a return pipe back behind the bumper reo, or similar? If so... I am currently making ~250 rwkW on a Neo at ~17-18 psi. With a return flow. There's nothing to indicate that it is costing me a lot of power at this level, and I would be surprised if I could not push it harder. True, I have not measured pressure drop across it or IAT changes, but the car does not seem upset about it in any way. I won't be bothering to look into it unless it starts giving trouble or doesn't respond to boost increases when I next put it on the dyno. FWIW, it was tuned with the boost controller off, so achieving ~15-16 psi on the wastegate spring alone, and it is noticeably quicker with the boost controller on and yielding a couple of extra pounds. Hence why I think it is doing OK. So, no, I would not arbitrarily say that return flows are restrictive. Yes, they are certainly restrictive if you're aiming for higher power levels. But I also think that the happy place for a street car is <300 rwkW anyway, so I'm not going to be aiming for power levels that would require me to change the inlet pipework. My car looks very stock, even though everything is different. The turbo and inlet pipes all look stock and run in the stock locations, The airbox looks stock (apart from the inlet being opened up). The turbo looks stock, because it's in the stock location, is the stock housings and can't really be seen anyway. It makes enough power to be good to drive, but won't raise eyebrows if I ever f**k up enough for the cops to lift the bonnet.
    • There is a guy who said he can weld me piping without having to cut chassis, maybe I do that ? Or do I just go reverse flow but isn’t reverse flow very limited once again?
