look at all these people with mods tho.... hicks is pulling 13.7 (BEST)  

and he's got 14psi, POD, full zorst, FMIC.. all that...  

if you can pull a high 13 stock, why spend $2500 on those mods ?

hence my theory of not getting a stocker in the 13s....

Traction a big part of drag racing is the 60ft put some slicks on that sucker and watch the times tumble..

not much differance? go learn what mods do to a car kabab.. i woulda thought u'd have half a clue considering how long u been on forums. Exhausts.. especially on turbo cars help, not just by the better flow but by the inherent boost increase which comes with this better flow etc. So an exhaust is a decent mod for a car. put a stock exhaust on and see how asthmatic your car feels especially top end.

As kabab said, on the R33 GTS-t, you will maybe gain 1-2 rwkw by doing the cat-back section. This is because the restriction is found in the dump pipe, not the cat-back section. After going the dump, front pipe and 3" cat, I noticed a HUGE increase in power, but didn't notice any power increase at all when I bolted the cat-back section on.

Air filter was probably good for another 1-2rwkw...

So at that stage, I managed a 14.3 with a STOCK CAR (plus 4-6rwkw in mods)... Hardly earth shattering mods.

I have got a 13.8 sec pass with a mildy modified R33.

The conditions were as per the signature below. Namely 8psi ,over 100kgs in the boot + boxes of crap on all the seats and little 205's.

Having said all that my car is not stock (ie: it has mods). I don't believe the factory stock car could get past a flat 14 or 13.9 tops. If the stock turbo was taken to 20psi for one run (might take a few turbos before it did a run without blowing up) it might get a mid 13. Quite a pointless excercise.

Nissan slacked off on lots of areas from factory. Thus far the only mods to my car have been to correct the cheap ass inefficient parts. All the mods have added something to the power but not effected the fuel ecconomy exept to improve it.

Next trip down the 1/4 I'm trying for a flat 13 (with new clutch and light flywheel), big ask for the 205's but it will be fun trying.

Well it isn't "stock" then is it...every little mod makes a difference.

kabab, you've gone off topic.

Last night you said a bone stock R33 GTS25T can pull low 13s, no exhaust, no boost, nothing, except slicks.

Considering Andrew was trapping at 95mph, with a couple of very minor mods, a 93-94mph trap speed has no hope in hell of pulling a low 13 second pass, even on slicks.

You say most of the R33s you see are running low 14s with crappy 60 foot times, don't forget, most of the guys here are running modified cars, not bone stockers. Nobody above has the said car.

I dont think any of the guys here think its possible either. That is all :D

Argh, this is a frustrating thread, so much misstruth's flying around.

Firstly Elf fuel will only give horsepower if the engine is tuned for the fuel. And the fuel will probably stuff up your oxygen sensor and cat and perhaps even rubber fuel lines.

Also a quicker 60 foot time will improve your trap speed, which is kind of obvious. if you get off to a better start then you have more track to gain speed. That being said a "stock" (No exhaust no mods full stop) will be lucky to get into the 13s, however one with full exhaust pod and somehow tuned for the elf fuel, with slicks would go close to a 13.3

Bab out of all people you should know better.

Throw in a tank of ELF on a stock R33 and watch how crap it will perform without touching a thing. Mainly because of the high density of the ELF fuel, it burns much slower, so running standard timing and fuel maps will run rich and crap. The reason they retune for racing fuel is advance the timing to ignite the mixture earlier so it has time to burn and have it burn complete for more power. It will produce more power because there is a greater force on the piston earlier and at high rpm it will ignite the mixture before TDC instead of later (with ignition lag obviously). So whack slicks and ELF in a bog stock R33 and it will go worse than another on street tyres.

Id say most people with these times just need a bit more practice at drag racing...ive been my few times and hell its not easy to launc hright, anybody can drive down the track, but to launch quick and quell wheelspin (like Merli's learning!!!) is very hard and takes a long time to get it right...

but then Merli's 13.1 was still hell impressive so congrats bruddah!

Finally, someone agrees with me that ELF will be useless unless you can do something with it... then by modifying the ECU it will no longer be a stock R33 GTS25T :D

I agree, bring on a demo... im not paying.. not my claim to prove ;)

Well, its not stock either (bleed valve for 9psi, no zorst, no pod, nothing else), but I ran 14.2 the other day. That was running on R tyres, so they are a fair bit stickier than regular, but not full slicks.

Unfortunately we did not get 60' times so I can't tell you if they were good or not. Trap speed was 96mph.

But this does seem to suggest you could get high 13s in a stocker with a great launch. I could only go to about 4000rpm off the line without significant wheelspin, so there is probably time to be made with better tyres.

if you want to find out the time of a stock R33, my car is available :D  

oh and my tyres are kinda due for replacement...does this count as slicks LOL :lol:

heh, she already offered. ;)

Sounds good Shell, wednesday week?

:burnout: :burnout: :burnout: :burnout:

exstaic ran a 13.8 with exhaust and s-afc running street tyres 10 12 psi I think mid 13's are possible may be a 13.4 babs is on the mark you dont need a bigger cooler unless you are fitting a bigger turbo in reality merli made reasoanble power witha stock cooler.

meggala

I ran a 13.9 at 101 mph at Eastern Creek on 4/12/2002. I have a sedan with 2 3/4 inch exhaust from cat back, pod filter with a cheap UAS partition and running 8psi. I can't run anymore boost due to spiking problems.

That day was really hot (36 celcius) and I had 5 runs. There was a group GTS T's together that day. During daylight none of us could break into the 13's or the 100 mph. There was 5 of us and we were doing from 14.1's - 15.1's at 93-96 mph. Would you believe as the sunset, these times did not really change ???.

On my last run after the sun had gone down I let my rear tyres down to 18psi, choose not to do a burn out as this only heats up the intercooler and ripped a 101 mph 13.9. I don't believe any of the other guys with GTS T's managed a 13 sec or 100+mph pass that day.

Unfortunately we were not getting our 60 ft times that day so I can't really compare 60 ft times to see whether that is where the difference was, although I'm pretty sure that the 13.9 would have been a result of a good 60 ft time.

Guest Skyline King

Guys.........

when TRY09s was 4ORCD (stock at first) it ran a 12.8 @113mph

it had a 3" exhaust ,pod filter,standard auto not manual,1 bar of boost and avgas and tolunene it ran those times with street rubber not slicks 1.8 60 foot.

exhausts make a HUGE difference to a skyline about 30-40bhp

and an air pod about 5-10bhp,most skylines don't like boost above 10psi as the ignition starts to detonate so hence the racing fuel,you can make 260bhp with these mods and tuning but as soon as you go back to std fuel and setup your looking at 140-160bhp.....hope this helps everyone....

thank you

    • Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi 
    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off. 
    • I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell.
