yeah like dezz said 193kw. running wolf3d. 60ft time 2.3 which is what most others were getting with same mods and power as me. 100km in 5th is the same as you guys 2600rpm. mechanic suggested clutch slipping but i think i would have notice that. also maybe cat has caved in? its only about 5mnths old though.

oh and what igzactly is granny shifting?

having the cat caved in shouldn't affect it much unless it has caved in and is blocking the air. normally when they cave in they just blow out the exhaust.

it could well be a slipping clutch. remember that the strip is a lot stickier than the road, so there is more chance of it slipping. many people have fried clutches at the strip that were fine driving on the road.

your gear ratios are a touch taller than most. i checked mine yesterday and i do 3750rpm at 80kmh in 3rd (like the others) but that shouldn't make that much difference.

what rpm were you changing at? was it chirping gears on the changes, or would it rev up for a split second? how many runs did you get done? was there anyone there with similar mods that got much better times?

and most importantly, did you have your windows up or down, and was the aircon off?

if you had the windows down, then that is your answer right there. that makes a huge difference at 100mph.

I ran 14.1 @ 106 miles at the drag day. My car is very similar except running 1rwkw less (192rwkw). He has Wolf3d i have a SAFC. He is also running 14psi, im running 12.

So i was getting an extra 11miles over the line with basically same power.

I know Jason didnt run with windows down, as no one was able to anyways. Im guessing the aircon would have been off aswell.

yeah windows were up, air con off. chripped a little from 1st to second thats bout it though. tried changing at few different rpms didnt make a difference. was changing at 6500, 7000, 6250 still the same.

dezz, mark and leigh had same power same mods. leigh has a slightly different engine thinks its been bored out to a 2.6 but still running same power. dezz got same as me 14.5 but he was getting through his gears.

think my cars just a dud. ive got to run 2 more psi than everyone else to get the same power to start with. dont think they are running a pod either. stock air boxes.

im runing a pod.

Sometimes i hear that running anything above 12psi doesnt really do much.. maybe try and reduce it to 12 and see if it makes a difference. It may be dieing off when it gets up around 12-14 anyways!

maybe take it somewhere else to get her tuned ??

think my cars just a dud. ive got to run 2 more psi than everyone else to get the same power to start with. dont think they are running a pod either. stock air boxes.

yeah thought about that. did a bit of research before i went to sabaddin but he checks out ok. heaps of people recomend him. hes on the actual wolf3d add in hot fours as a dealer and had his first car at 14 running on wolf. hes grown up with it and im sure has had enough experience to know what hes doin. but cant hurt to have someone else have a look. might get it dynoed again at sabaddin just to check ive still got the power i thought i had. does feel sluggish now but then again it doesnt take long for you to get used to the power when you increase it.

If you're getting 100KMp/h @ 3100rpm in 5th, you've got a 4.375:1 diff, ie R33 auto diff, same ratio as most RB20 R32's. I've got the same ratio in my HR31 with RB25 box. It can be a bit of a pain on the highway (really could use a 6th gear) and you basically never use first unless you've practically come to a stop.

With standard 4.11:1 R33 manual diff you should be getting around 2800-2900rpm for 100k's in 5th.

yeah thats how i see it. if it dies i'll just have to go hiflow. in a way im hoping it does. but as it turns out i might be selling my car. need a ute for work. roof racks on a skyline? i dont think so. so touch wood my turbo doesnt blow. only problem with selling is, have you seen how many skylies are for sale? theres like 9 pages of them on car sales. be nice to hold on to her and have a ute but cant afford that. only had her for eight months.

yeah cubes thats something ive been meaning to check out. dont have a hand controller or boost gauge so i'll have to find out when i get it dynoed again, if i even bother trying to fix it now.

    • Hey all  im wondering if you can help me please I have put a rb20 box in my r34 gtt as my auto packed up and a friend had a spare box I know it’s not ideal but it will get me up and running for now. we have done the conversation and everything is working great but my Speedo we got a s13 speed sensor but my Speedo reads double now and I bought a speed converter but still not having any luck.  so I thought I’ll reach out and pick your brains  any help would be appreciated please as I wanna drive my car again 
    • Drain it. I got official Matic D but you can get whatever is listed as Matic D compatible.
    • Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻   
    • Nice car! I’m glad folks in the US have gotten past the FnF and are buying real cool cars like the 260RS I was with a bunch of mates in Portland about a year ago and spotted a green Stagea (just a regular 2.5T AWD) parked about 2 blocks away and they were like “a what?” So I made a bet with them for a round of beers and said “ok one of you run down there and tell me if the steering wheel is on the correct side” 5 mins later the American comes trudging back up the hill and goes “he’s right guys. Ok what beer do you want?”
    • Should replace OR drop the tank, give it's good clean. Might be worth replacing that entire fuel level/pump/cradle thing with this: https://frenchysperformancegarage.com/products/fpg-s13-180sx-r32gtst-single-pump-hanger-kit-billet-hat-6-v3-fpg-089?gQT=2
