I want 12's!

[riggaP]

I want my car to run mid to high 12s. Heres my plan:

Trust V-SPL coola 600x270x76

K&N pod with cai

Full stainless 3" exhaust including dump

s-afc

boost at 12-13psi

255 street tyres

everything else stock

Will that be enough? I may also add a heavy duty clutch if I need it. At the moment the only mods I've got are a cat back zorst and k&n pod and best so far is a 14.307@98mph on 205 tyres at normal inflation.

What hope do I have?

Have a look on the SDU forum, Rev210 is on the same mission and is getting consistent mid 13s with a couple more mods than you have now

I think you'll need alot more then that. If you look at how rev got a 13.4 he did alot more then you and still only got that. It'll take alot more to get under 12.

[Doctor]

With those mods you want you should get about a 13.2?

Youll need a bigger turbo, T3/4 or TO4 should do the trick with a larger fuel pump and fuel pressure reg. Dont run huge boost due to high compression in 33's.

reduce the pressure in your rear tyres.

Knock your timing to around 18 degrees.

Run very good fuel 100+RON

Make sure tuning is spot on.

That should get into the 12's if you know how to launch well.

I think you may need a bit more, I agree that rev's car is getting close, but it is a freak. I think a 13.2 or 13.1 would be achievable with that setup, but feel free to prove us wrong.

I also am aiming at high 12sec 1/4.

i've got turbo back exhaust, high flow turbo and cat, pod, FMIC, and profec b EBC. Saving for larger fuel pump, fuel pressure reg and a powerFC.

Would 12s be possible when finished?

Mate,

Check out my 13.4 'how to' thread. Do what I did. It will cost less and if you add the 255 tyres (I'd go simex to get more traction for your $$$) you might crack the 12's without the S-afc.

If you can get the 60ft down to 1.9 a 12.9second pass is on the cards if the car is a carbon copy of mine. Think about it 12sec pass without any extra fuel management.

here is my thread about the 12sec. pass.

MRK25T,

With some sorting out 12's can be achieved. The signature 1/4mile you have indicates some serious problems tho'.

GTS-vspec,

My car isn't the freak. I am baby yeah!

Just let me break....er....tune your car like mine and times will tumble.

I checked out that thread... the reason for starting this one . Over your setup I'll have a full zorst, pod with cai, safc, 3psi more boost, and bigger tyres... minus the flywheel and pineapples. That should be worth more than half a second right???

Rev210,

I haven't been down the 1/4 mile yet, I just felt left out not having power figures or 1/4 mile times in my sig.

What sorting out do you mean?

[GTS-t VSPEC]

MRK25T,

With a hiflowed turbo then you can get 12's not problem, the stock turbo really limits the achievable power, but even still 12's are possible.

rev, Yes you are a freak, who else would buy a V8 Volvo:lol:

I have a full exhaust, the turbo to cat is thermo wrapped.

The Pod isn't any better than the K&N panel filter I have.

There are plenty of guys with a S-afc, more boost and big tyres and such who don't even crack a high 13, let alone a mid 13. What you are proposing dozens of people have already done and have not achieved even 13's let alone 12's.

The pineapples are a 'must have'.

The flywheel alone is worth 4 tenths.

The larger intercooler might hinder your 1/4 mile time if you are using the stock turbo, unless its rated to 300HP or just under. Besides I don't think you need to spend the money there to get the 12's your after.

Have fun trying, I know I always do.

[GTS-t VSPEC]

Yes, many people even with that setup are getting embarrisingly slow times, alot has to do with learning how to race the car, I dropped a good 8 tenths without changing anything, just learning to drive.

See'ya:burnout:

[meggala]

my little rb 20 is on 14.00 @ 98/99 mph and the car still has 3 tenths in the 60' I reckon more boost and more tuning its the fine tuning that counts not the oput right hp.

my believf is th r=un 12's you will need a bigger turbo or to cut weight substationallly

[meggala]

btw if your on the east coast rev210 has an edge he races at motor plex there is nearly half a second time difference there

meggala

[rev210]

meggala,

I know your only joking when you say that.

I reckon we have more high 14 sec GTSTs per head of population than anywhere else, motorplex or not.

[riggaP]

OK so basically with the setup above plus pineapples, light flywheel, high flowed turbo, slicks, all professionally tuned, and with me learning to launch it properly, 12s are possible.

A few quick questions,

rev210: why the pineapples? You say pods arnt any better than panel filters. So why is it that almost any hi po car in magazines use pods not panels?

meggala: did you shave almost a second off by just having good tyres/suspension setup? Do you recommend hard or soft suspension?

Hey Rev, out of interest what yr model is your GTS25t?

Matt - he has a 1995 model. I swear the 1995 ECU's have different maps. When I run mine up on a dyno I'll try the 1995 and the 1993 ECU's I have and compare.

I found a web site in Japan that quoted all the different firmware updates for the nissan ECU's, and just in the R33 GTS-t's there is about 7 different versions !!!! But they didn't say what the differences were

Rev210 - a bit off topic, but did you wrap your front/dump pipe in thermal wrap while it was still on the car, or was the pipe off when you did it??? I'm thinking about doing mine and I just hope I don't have to take the damn thing off to do it
