its not quite a 13.7 but...

[adam 32]

GOT BOOST, how big a cooler are u running? whats the optimum size u know? my car cam from japan with a cheese grater/intercooler on it, seems to be doing the job for now but i may replace it at some stage (unlikely due to funding tho:P)

btw whats a GTS-R?

[GOT BOOST]

this is mine before i got it tanked

core size bout 350 high 600 wide and 100 thick race core.

get the biggest you can fit.and i'd reckon mines bout it.

without big mods.

[adam 32]

wow. did u remove the front support bar to fit it in? still running the std front bar, what hacking up of it have u done to allow for max air flow. can u post a pic of the cooler on the car?

On the subject of Zed 1/4 times.

The Wed. that I was down a friend drove his manual 300 down the 1/4 to a best of 13.1, and from memory all he has is an exhaust and boost. Respect where it is due, whether it be for the car or the driver.

[osc@r]

Rhino..

Sorry, but i find it VERY hard to believe that a 300 with only boost and zaust can pull a 13.1.

The TT models were quoted in Japan as 1580 kilos, pulling 14.5's in stock trim on 104 octane local fuel. There's a big step from there to 13.1 Maybe your mate has a little more under the bonnet than he lets on.

[GOT BOOST]

cut out some of support bar.but its still the standard bumper

had to remove grill section at bottom only and some of the bits that hold fog lights in nothing major.

the guy who fitted the tanks and pipework works from home and he's never done car stuff before (alloy boat builder).mine mounts the front of the chassis rails and ties into bonnet catch at top.

i will get you a pic soon, pity i didnt take one with bumper and support off it looks awesome then. its tapered at top to fit under headlights its so wide

[adam 32]

as i argued in the other thread, these times are a LITTLE fast

i have 4 mates with zeds (1 has 2, dont ask:P)

1. completely stock - 14.2

2. filter exhaust - 14.34

3. filter exhaust boost(12psi) - 13.8

4. filter exaust boost SAFC - never ran down track but got beaten by shannon who runs 13.6 - approx high 13s

5. twin td06s, full race engine (475rwkw) - 12.6 spinning the whole way

from this i conclude that low 13s and high 12s are impossible with only filter exhaust and boost on a 300zx

Ok , I think we can leave the arguments aside now and perhaps look at the more productive and interesting questions like :  

How to run a 13 with less than 200rwhp.

And

How to get a quicker launch and 60ft time in your skyline on race day.

Put it in a pintara station wagon with a single spinner diff

then youll get 13.8

But in all seriousness ive been to all but one wednesday drag meet this season, and the biggest problem i see with the r33 drivers at the drags is too much wheels spin

too Hard launches

try slipping the clutch a little go get moving and get boosting then once you are moving gradually apply the throttle, im sure your times will not suffer from this method, though your clutch may do.

I've been in contact with the guy who ran 13.1 in his Z.

He has the following mods:

Exhaust

Boost

Replaced the radiator fan with an electrically driven one ???

225 tyres

aftermarket sus.

clutch (6 months old)

And he has the heater on full bore when going down the 1/4 (he thinks it helps??)

He does a smallish burnout before each run. I'm not sure what the purpose of replacing the fan fulfills and I'm not sure how beneficial having the heater on for the run is but you can't deny the timeslip (I forgot to ask the terminal, I'll try to find out).

'Blame' his quicker time on the better aerodynamics of the Zed or the different rear-end setup of the R33's and Zeds, but at then end of the day I think it comes down to actually being able to get the best from your car. I'm the first to admit that I'm a long way from doing this with my R but I'm lucky because the 4WD takes a lot of the hassle out of the launches. But the more quick Skylines around the better in my book and things can only get faster:uh-huh:

[skyzerr33]

Ryan replacing the fan with an electric one gives u more hp to play with as the electrics are working the fan not the engine

same goes for the water pump.

[Guest Rhino]

I thought it was something like that, cheers Troy.

i swear your drag strips must run downhill

Actually i think the motorplex is the most downhill in aus, it drops the most over the quarter that the regulations allow, so we should have the fastest track.

As for the z's, they have an insane amount of straight line traction, must be a combination of a little extra weight, and a good suspension set up. (Not much sideways traction though!)

I reckon the extra grip, the slightly bigger engine = more torque, and the two turbo set up brings boost on earlier, again more torque. Thats gotta be the difference.

yep thats my mate who's zed run 12.56 i think it's best mph was 116.5 too i think! as a matter of interest i raced his brothers z the other night and i got him off the line by about 1/2 car but by about 80k's he just flew by and pulled about 3-4 lengths on me! his car has a 2 1/2 cat back system (cats-modified) 12psi, hks pod filter, loosened (3000) std convertor and thats it, i think the reason i got him off the line is the fact that his car wheel spins quite abit due to the 225 tyres being abit small/crappy!

[giz01]

the fan on the z is supposed to be multi speed or something so it really doesnt cause that much of a drag on the engine apparently

plus electric fan will not pull in the same amount of air either when required! plus a zed will pick up a heap of power from the filter mod compared to a sx or line! TTZ went from 14.2? to mid 13 on the street but i guess it possibly picked up some boost from the less restrictive intake maybe?

[giz01]

i was wrong mates z run 12.59!

Regarding our Drag Strip..(Perth)

Apparantly we have the best conditions on the Earth..

What with hot dry days for track prep...

Cold sea breeze (Fremantle Doctor) arriving mid-late afternoon

And really sexy chics to spur you on...

Why wouldn't ya!?!?!

[giz01]

hey from memory with couple of small mods eg advanced timing , boost & fuel one of the sub zero's skylines ran 13.2 or 13.4 plus it was auto when nearly std! So wats this ***** low 14 sec or high 13sec stuff all about? They didn't need pineapples or any of this other crap! just GOOD simple mods & good driving i guess!

[Hicks]

Drag racing is a skill that I doubt anyone here has mastered, or come close.

John tang's silvia pulled 11.4, but he wasn't driving. He hired someone to race it because the only times he was getting was 13's!! Imagine havin a 11 second car but could only pull 13's, You'd be pissed!!

[PSIKO]

If I were pulling 13's on an 11second car...I'd seriously be thinking about either having some lessons in how to drive, or giving up on taking my car to the motorplex ever again

he must've gotten a better time than 13's??
