Been playing with the GTR a bit...latest mods are an E85 conversion.

950cc injectors, HKS GT600 fuel pumps upgrade...and a tune from Willal.

Im also using the Sucrogen E85 (same stuff the V8 supercars use).

Result was 400kw atws..the thing is damn quick....leaves black lines from each tyre under acceleration in second gear.

Off to WSID on Wednesday to see where its at....then off to the Temora 1000 next weekend followed by a track day at Wakefield on the 27th.

Thanks to Martin at Willal for tunes

HKS pumps and 950cc injectors

awesome mate

keen to know why my car made more power on the same dyno and same fuel

what else do you have on the car? be interesting to know if you dont have an intake for eg, working out how much power it's worth working backwards from our dyno plots

in for your 1/4 times. I got rained out last sat and couldnt run

Edited by domino_z

Different dynos, different days, different fuels, and you had bigger inlet pipes etc domino. That explains most of the difference! :)

Other than that the tunes are fairly similar

How similar is fairly similar. I bought an email tune off you a while ago which is great. I have the cobb AP (Opviously) DW950cc injectors, HKS pumps, your (Willall) midpipe, the same down pipes as domino_z and ADM 2011 turbo inlet pipes (bigger ID).

Will one of your email tunes for E85 with confidence give me the same results as these guys with no issues?

Does your email tune cater for my specific mods? as I dont really want to have to take the car to SA if I can help it.

I will be running the sucrose E85 from the drum, will that make the tune different than that of domino_z which was your E70 tune?

Is there much of an advantage in getting the car dyno tuned by you rather than email tuned by you?

Do you need cobb data to do the email tune more accuaretely?

Sorry Martin for all the questions but I am really interested.

the way i understand it, given the willall maps have been based off running as low grade as e70, putting in sucro wouldn't really make that much of a difference - a bit like choosing bw different brand 98 rons

i may be wrong though, and if there's considerable gains to be had from the sucro juice, ill be coming past your place G35 for a top up before hitting the quarter :thumbsup:

So, went to Eastern Creek dragway last night...mixed result.

ran 10.96 @ 127mph

Had two runs....

First run the launch didnt feel clean so I got off it and braked at 3/4 track (to keep above 11.00)....ran 12.1 @ 69mph

Second run launch felt good so I stayed on it....

Looking at the data in my Vbox I should have stayed on it the first run..it was running strong at 7.0 @ 103mph half trrack and my 0-100klm/h was 3.0 sec ...second run was 3.2 sec

Looking at the video below you can see that the car actually bogged when shifting into second. Its hard to tell but 1st gear was all wheel spin (I had an aggressive 4000rpm launch map) I shifted at the rev limit but because of the wheel spin the vehicle speed was not there and she bogged...(the tacho goes as low as 3000rpm after the shift).

The bogging down probably cost me 2-3mph and a few tenths.

Looking at a heap of timeslips on the US GTR forums you can see low a 1.6 sec 60 foot is the norm....I think I would have nailed a 1.6 with a few more runs but there was no chance they would let me back on the track..

Enough excuses...

In car video of the run

Edited by Speedah

so what happens now, did they write down your numberplate so you cant go back

If you run under 12.00 (which I have done in the past) you need an ANDRA licence..the 10 sec pass is logged against you ANDRA licence number...

Someone else could take the car and probably get away with running

Speedah, do something about those brake temps before you destroy them.

This guy seems to be onto something - http://www.nagtroc.org/forums/index.php?/topic/61425-willall-gtr-brake-cooling-system-track-results-updated/

As the only effective brake cooling system that exists in the world for GTR its worth your consideration.

Forum sponsors CRD and Mercury both sell and install WR35WS :)

New wheels and springs installed today

Advan GT

20 x 10 front

20 x 12 rear

with 285 and 335 Michelins

Also fitted 1in lowered swift springs...these springs actually lowered the car 3/4in at the front and 1/2in at the rear.

Pics dont do it justice...looks very fat on the road.

Thanks to Michael at Acute Performance in the USA for a perfect transaction on the wheels/tyres and springs

I have also just done the 2012 front end conversion

    • @soviet_merlin Thanks mate!  Nothing too major but will hold me up for a while. I've got lymphomas to get taken off the back of my neck and the middle of my spine which always conjures scary thoughts!  It sounds worse than it is. Yeah great, conjuring more rabbit hole deepening , just what I need! 🤣  
    • I'd argue the F50 kit I got is very good value. For ~2k I got the calipers (refurbed condition), adapters, pads, brake lines, rotors, and top hats. I think you'd be pretty hard to get Evo/GTR/350z brembos + the additional hardware for similar money. Used market for a pair of front calipers alone I've seen tend to run anywhere from $1500-2000 depending on condition.    That said, something like a GTR or 350z brembo is a lot easier to adapt to the Silvia. 
    • Is there a significant price difference between the Evo/gtr/350z brembos vs the F50? Looks amazing.
    • I was actually being a tightarse at the time LOL... My OCD is tickling me into running a 2nd 8AN Teflon hose all the way down and removing the 2x OEM hardlines. My other side of my brain is telling me to run 2x hardlines front to back (also acts as a fuel cooler, so win win).
    • As I mentioned in an earlier post, I had some trouble with the Silvia's brakes dragging back in 2023. I managed to sort it out then, but the same problem came back to bite me late last year. Just take a look at the picture – I had a feeling the handbrake was acting up again, and I was right. Anyway, I'd been wanting to upgrade to bigger brakes for a while. Not that the Silvia's brakes were bad, but it was more of a "want" than a "need", you know? It was funny, though – at the time, I couldn't find any Evo Brembos, 350Z Brembos, or GTR Brembos for a decent price (of course, tons of them popped up online after I already bought my kit!). I ended up going with an F50 Brembo kit, which came with adapters, brake lines, 330mm rotors, and top hats. The F50 Brembo caliper was used in a few other cars too, like the FPV. I also decided this was the perfect opportunity to ditch the Silvia's ridiculous rear brakes and that awful handbrake (some of you were definitely right about that!). I picked up some R33 calipers and all the necessary bits – rear drums, backing plates, and new hardware to refurbish the calipers. Of course, it wouldn't be a project without a few hiccups. Turns out the brake master cylinder was playing up and basically (to put it simply) keeping the brakes engaged. I had it overhauled, and after some adjustments, everything was working again. The whole process took a while, as you can imagine. To top it off, the front right wheel bearings were shot and needed replacing too. This is a rare occasion where I'm posting an update while it's all still fresh! These pictures were taken just this afternoon.
