Severe Turbo Lag...suggestions???

[Vejita88]

Mk, here's the deal, im running the OPTION Stream Z '04 and noticed that it has a severe lag on the low RPM range. does the turbo do this, or is the engine suppose to run like this


thnx for any suggestions

this car has serious handling problems. better take (one of the) z lm versions to do whatever you're doing and sell the option car asap.

 

[Vejita88]

how much are they?

 

[Greycap]

You'll get one from the Japanese Championship and another from the All Japan GT Championship for free. The latter one is better and can also be bought for 1,350,000 Cr from the Nissan dealer if you don't want to wait until you win it. Look for Nissan Motul Pitwork Z (JGTC) '04.

Nothing you can do about it, except make it rev by holding X and square, then let go of square, hoping you burn out. Burnout is better than lag in this car. Also make it have close ratios after the first gear. I made mine shift to second at 65MPH, so when I finally get it up to speed, it would always stay in the rev range.

 

[Vejita88]

alright, i appreciate the help guys.

thnx

it has good power when it is close to red line but before like 6 grand rpm it has a lag of power. I kept the car because of the color

This car was bade for drag races and high speed runs as far as I know. It has two planet-sized turbochargers, and even the bored up engine is struggling to deliver them enough exhaust gases to make them spin. There's one more solution, and it's throttle in the bottle.

Run some high-speed races (Test Course?), and rack up some money to buy a better car. I won some racing series with the Option Z, but it was more difficult than it should have been, given the base chassis and horsepower. It's all 'show', and no 'go'.

 

[Renoff]

buy the amuse carbon skyline lol it has no lag whatsoever (not) try that falken rx7 it might be a goodie to use

Are you sure about that? I was able to beat a Nissan Skyline GT-R Concept LM in this car, by 10 seconds on 4 laps @ Deep Forest. All I did was add RM tires, ratios, and suspension settings.

Wow, racerx, you now have a "Crackhead" rating.

Smooth move, ex-lax.

 

[Gil]

The Option Stream Z is tailor made for drag racing.
You'll have to futz with the chassis to make it an efficient drag car.
On tracks with turns, your options are to play with the tranny till you get the car to run well, but it will continue to lag due to the sheer size of the turbos.
It is very fast, but not real quick.
It can be driven fast by very skilled hands, but there are so many cars that are much easier to drive.

 

[Rotary Junkie]

Waiwaiwait.

It's tailor made for drag racing yet it runs a bodykit with canards and a JGTC style wing? And it has road race slicks? HUUHHN?!?

Ummm, downforce maybe? And maybe the slicks are used for grip?

 

[Greycap]

It's not a drag race car, but a high speed open road racer. See Silver State Classic Challenge to see what it is about.

 

[Parnelli Bone]

I'm personally glad turbo-lag is back in gT4. I missed it in the 2nd & 3rd game!

 

[Rotary Junkie]

Thank you for the clarification, Grey.

Loon: Hmm... Last time I checked, downforce creates drag, drag hurts acceleration... Drag racing is just an acceleration contest. Drag slicks create more forward grip than road race, and are traditionally quite large (For the Zs power, 28*10.5s should work with a good suspension setup).

Thank you.

 

[Loon]

Isn't downforce also used to keep the car planted on the ground? So it won't flip?

I'm pretty sure all drag racing cars have some kind of equipment on them to create downforce, its a fine line of how much downforce you want so you won't lose acceleration.

 

[Leonidae]

BTW, this particular car crashed due punctured tyre.. promising isn't it? there wasn't much left afterwards..

 

[Rotary Junkie]

Loon: Actually, for "sane" speeds (slower than 6 flats in the quarter [even that's insane]), it's all about lowering drag. Then when 250+ is fully realistic through the traps, wings that actually produce downforce start getting used.

 

[Vejita88]

mk, i wasnt using this car as a drag car, i was running it in the GT World Champ race and thts when i realized the severe case of lag. anyone for setup suggestions?

 

[dimplz]

sell it and use the formula GT F1 car with baslist weight 20kg at -33

 

[Gil]

Waiwaiwait.

Ok, for straight line exhibitions of speed.
I imagine that it would do well in the 1000m dash at the Test Course.

 

[Rotary Junkie]

Well... It is suited to Like The Wind more than anything else. Launch WILL be a problem.

 

[Vejita88]

mk, im rid of this car now..c if i can find a good replacement.

 

[Rotary Junkie]

Hmm... Stock Fairlady Z. (z33)

 

[Orion]

Well the Nissan 350Z is much lighter than the Fairlady Z I heard, maybe he should consider that one. It is around 1350Kg, which is lighter than ANY Skyline GT-R with 276HP+.

 

[Leonidae]

And tuned with supercharger it'll deliver low 1'43 on GVS with wing and R3's. MFT version is already finished and waiting for it's time..

not really as im an avid racer and spent the day down a dragstrip today only the fools in supras seem to have mahoosive wings on the rear which really is just slowing the car down,.....not that it stood a cats chance in hell against all our escorts running fractions of the power on totally stock bodies

to be honest its only top fuel cars that benefit from wings as there crossing the line at 200+ mph so you kinda want a bit of stability
