Maybe, @stealthfoz dynos are all different..

Not too worried as it's not a race car only diference to run down is ET streets rather than the nt05's.

What setup is the s13?

Should be a pretty big weight difference?

Auto/stock manual/something else?

I've Still only done 2 full runs, just with a stock 33 box, maybe I'm also a shit driver haha

other run was 10.4 @ 143, still haven't gone full boost in any gear, nearly full boost in 4th but I've got it pulled out of other gears for traction, will be putting more boost into 2-3-4th gears next time, but I'm happy with 1st with the 1.4 60'

mine weighs 1300kg, manual. rb25/30.

its got an RB26 in it stealthfoz.

Everyone seems to think having a manual box and ET Streets is a big reason for not getting the et down but there are plenty of people who can do it so don't know why this car wont. I would love to have Royce's 60 foot time

^whats the clutch like?

The more i watch mates race. The more i think that anything more than

A big single plate may shock the tyre to much and you need that slip

To get the car to roll out a few ft before smashing the tyre

I know radials are a lot worse for that aswell

I would agree with that darren, ive stuck with a single plate for that reason, also bit lest shock for the gearbox, so they last longer.

You still on a stock bottom end??

Im currently sitting in the ~420kw bracket (same dyno as royce) with an r33 gtst so for argument sake say 1450kgs.. so in theory i should be running 130/135mph? I havent taken the car to the motorplex yet as i need to sort the diff and shafts out first but im very keen to have a shot and back up the figure hopefully.

Surely torque has alot to do with the MPH.. a 400kw 25 would run slower then a 400kw 30 would it not?

Even a 100kg difference between cars would have to have quite a toll on the MPH surely.

what are people's thoughts on the impact on the 1/4 MPH when comparing the 32 GTR with a 33/34 GTR.

500kw on a 32 would give you 140mph, however the 33/34 have another ~100kgs on the 32.

From some calculators online, it seem the MPH would be 3-4 miles lower on a 33/34 GTR with the exact same setup as a result of the additional weight.

Partially explains why all the fastest street GTRs are 32s...

I think weight is often over looked for sake of tugging over dyno figures.. Doesnt matter if your car is 2000kgs and 500kw if its not running 140mph alot of people will still just call BS on the figure and not even think to consider weight.. I recall afew years back mercury motorsports being criticised about there dyno figures because nitto (34) wasn't running as high mph as some r32 gtrs with similar power... in realitly it was a full weight road car with a cage lol..

Hi made 554 rwkw 6466 gen2  32went 10.4 @140.7mph  on a  1.8360foot was happy with mph

Done  a 1.52 60 foot snapped rear left shaft was really chasing a 9 on stock bottom end 

 

Tuned at jem

i did exactly the same. i lowered rear tyre pressure to 14 and Adam turned up the 2step. next launch snapped the rear shaft.

 My Speedo cable was out  so no 2 step was shattered after I did 1.52 60  as I'm on bought time with the stock box

 

What clutch are you running  usmair

OS GIKEN triple plate at the time.

Have now upgraded to a quad plate as a result of a misdiagnosis.

I've got a 6 speed GETRAG though

    • Put a camera facing your dashboard so you can film the gauges. Head out to a straight but of road, and filming it as you go from a stand still at wide open throttle to as fast as you can/feel comfortable doing. Then film the dash board as you for example accelerate like normal onto a freeway. This will give us an indicator from Speedo of your expectation of slow, and will give us the rpm reading too to see if it's shifting. (Auto still has tacho from memory)
    • Buy yourself the cooling system pressure tester. Being able to pump it up, and have a gauge on it, AND have a cold engine makes it much easier / practical to diagnose. Additionally as the engine isn't running, you can listen for pin hole leaks as well as watching if pressure drops away. In addition, you can pressurise and while doing so, watch all the little rubber hoses. Some fail very brittle, and will just leak, while others can end up very soft and bulge. While a bulging hose isn't necessarily leaking, one of those small ones starting to stretch / expand in a bad way is an indicator that you'll be looking to replace that one soon   Depending on if this is a project car, or you'll be dailying it in the summer months would alter how I'd be most comfortable with driving the car and how I'd replace. If you're planning to use it as a daily, with no backup, I'd pull the engine, and replace all the external oil/water lines in one big swoop. At the same time do the timing belt, water pump, tensioners etc. Do not open the engine at all. We just want to replace all the things that are inexpensive as a single item, but a PITA when they go. By doing the above, you've made the car from a bunch of age related issues more reliable. If it's a project, and you like swearing while trying to reach into dirty hard to reach places to replace a single hose that may or may not be the leaky one. Just replace the leaking/bad ones as they need it. If it's a project and you'd rather swear at the car once and enjoy it as much as possible, then refer to the process I mentioned in how I'd want to do it if it were a daily. However, the approaches above do come down to how much spare pocket change you have. Pulling the engine and dropping over a thousand dollars on parts, may not be practical for you. Oh, if engine outing, I'd replace as many silicon/rubber inlet joiners as possible too.
    • Yeah, they're pretty dumb though...ie; they'll throw a solenoid error if the solenoid is dead, shorted, wiring is open circuit, or even if the driver transistor has failed (they can't self-diagnose much, they can only test inputs/outputs)... but if you wanted to try, I believe it's this protocol....(uses a long pulse indicator with short pulse counter)...    
    • Yeah I'll do what I can without taking off any major parts for now. If it becomes clear I won't get far with the engine in the car I'll have to think about the next steps. I am not too stuck on keeping everything 100% OEM, if there is better solutions, like converting most lines to braided with AN adapters, I'd rather do that than buy overpriced new "shit" parts.
