The 3540 in 1.06 turbine is a huge turbo for a Rb25det, and he's only 3m/h faster, I think I can get that mileage on 23psi with G3 on MT tyres.

And yes I'm making an 11 blade wheel profile for the SL2 at moment. Aiming at T67's power with 20G's response.

The vid I linked was on a .82a/r housing - he got that mileage on ~20psi on pump gas, so comparing 23psi on E85 is hardly apples and apples. I wasn't trying to compare the GT3582R with your turbo anyway, the GT3582R *IS* a large turbo (on your boost level and E85 it'd push him WELL into the 130mph range) and it is, or at least should be a lot laggier as well.

All I was trying to demonstrate is that an R33 can get into the tens even with a manual if it has the power to trap at 125+mph

I was reading through the thread and was going to weigh in anyway, though looks like you're very much on the page I am reading from - so I'll +1 with with a bit more anecdotal evidence to support it

The ATR28SS15 would be a perfect turbo for your application. I didn't look into some thing even smaller as it doesn't make that much of a difference in response but did loses quite a lot of power. I'

^ lol... maybe I'll use a 3" intake pipe and add in more bends.. that usually gets the suuuuuuuuuuuuuuuutuuututuutut going LOL. Anyhow, some real world facts to back up the results.. errbody likes ti

Rizz89: Well if we did that high flow on the VL then it will be bit laggy for the Rb25det how ever it should produce more power due to larger wheel profile. Get Plazamaman's cooler kit, proper injectors and a tune.

R33's pretty heavy, is the Skyline in the video been fully stripped for drag? I will ask Trent to lose few pounds or askt Cat to drive for the next drag. :D

Nah I don't think so - though to be honest it was a long time ago so memory is a bit hazy but it was the owner's street car. The head light removal was just a thing done somewhere along the line to see if it made any difference from memory. The car was dynod at 450kw @ hubs as raced - I am sure there is no correction that you could do which would have brought it under 400kw (TCF was 1.00 and no AIT sensor manipulation was done) even though 450kw is a bit optimistic for most fair comparisons sake. It didn't have the strongest power delivery hence not being that quick for the power, it was running only 20psi and it's peak power was at just over 8000rpm and given that it was a stock motor/oil pump/etc he couldn't really rev it much higher to make the most of the peak power and hope to survive a run

Again not sure what the relevance is, I was just talking about trap speeds vs 1/4 mile times.

Hey guys
Good Results this time around at the drags :):):):)

12.807 @ 110.56 mph ( 177.92 kmh )

It was what i think a perfect launch.

hat was with Full 36 psi in my new KU36 tyres.

his shows you hypergears do go hard :):):)

340 HP Fyi

Congratulations on the time Jay-rod. Good tyres and more practice made a difference. Great work.

Artz: haha yes, having Trent sitting behind steering wheel is like me driving with light weight Porsche wheels with carbon fibra bonnet and boot, plus no interior. He's used to drag VLs with Nos also lot more experienced.

Pretty close to spot on Jay-rod.

340hp at the crank and aprox skyline weight should do 12.2 and 110mph as a theoretical best.

You do have more than that at the fly but this is using a formula to work it out. I think if you were to be doing 112 or so your HP would be spot on for expectations. So your results are good.

Didnt you guys run RSR's? In theory they are slightly better than the KU36?

Yeah I thought Federal RSRs were higher spec than Kumho KU36 too. :S

Either way excellent time Jay-rod - hope that I can get into the 12's my next time out.

I'm running RSRs. They are pretty good on road, probably because I rarely drive it on full throttle. They are not good drags.

Yeah i just mentioned it as i am running them too and at 360kw it grips up pretty hard in 3rd on a street surface so i thought a prepped track would be even better.....

Anyway, Back to the turbos :yes: keep up the good work guys!!!!

      Fuel Filter replacement

      By GTSBoy · Posted

      What's wrong with the OEM filter. They do the job perfectly. As to your actual problems. Stop driving the. Take it to a mechanic. If you actually do have a fuel delivery limitation and you are putting it under load, you could be killing it.

      ER34 AT ECU and HKS SLD pins

      By Duncan · Posted

      I don't know the answer, but my uneducated guess is this will not work (or, not as you want it to). I would wire the SLD into VSS1, I bet that is what the limiter uses However, I also bet the ECU compares VSS1 and VSS2 and throws and error if they are different. Best suggestion I can make is wire it into VSS1 and see how you go, I guess the error will only appear above 180 when then SLD is active. If it appears at lower speeds put a switch into the SLD earth (or power supply) and only turn it on when you need to go over 180.

      Fuel Filter replacement

      By Diomedes_ · Posted

      Hi all, So, looking to do some general maintenance on the car, as it has developed a some slight (related?) problems; Three problems that I think are related. 1999 R34 GTR RB26 - engine will sometimes cut out while left on idle, but will keep going if I keep throttle input. Usually after having driven a while. Its random, somedays wont happen at all, others will happen once or twice in a half hour drive. - Second issue is that while driving, the car will sometimes not be able to get past 3k rpm, no matter how much throttle input I apply. - Lastly, car will sometimes be real laggy climbing through rpm, but if I apply lots of throttle problem will seem to clear and go back to normal. All issues come and go, again somedays no sign of any problem, other days will just be stuttering around for ages.   I think it might be either the fuel system, or maybe the AFM?   Either way, I am going to clean the AFMs, and replace the fuel filter, use some injector cleaner in the next few fill ups, and might look at doing the fuel pump aswell.   Question I have, is filter such as; https://www.efisolutions.com.au/pro-fuel-filter-30-micron-an8-orb-black Fine to replace the normal filter? Their product page says as a prefilter only and not as the main EFI filter, so I'm guessing I would still need the stock one? Can I get an aftermarket one that has AN8 fittings to replace the OEM one? Or is the OEM one just something you have to live with?

      I say this and there’s a Nistune r34 GTT MT ECU for sale on eBay.de but I need to figure out compatibility between the AT harness and MT ECU - TCS considered. I figure this HKS SLD is a quick bandaid anyhow.
