-7's on 98 wont make 320-330

or

-7's on ethanol wont make 367

or both?

on top of Dyno's being a tuning tool.

Never had same results from different shops. I have Dyno charts that vary by 50kws

R/R seems average for ESP

Shoot 6F not 8 as it is sometimes to give better readings.

I don't know the capability of -7's on ethanol. What is their max?

Look Team,

Iv'e had heaps of fast cars, and this one seems nice and punchy. Even if it's within 10% who cares... It's still a built GTR.....That runs on Ethanol and a Haltech.

Feel free to meet me on the 24th of Jan at Wakefield for the fifth gear trackday. I'll be there as per usual, not hating on a keyboard.

Cheers. James

Great power James. You were a monster on the track day and given this power you'll be hitting 1:06's on the 24th? haha

Don't worry about the haters, everyone is going to have their opinion with a select few actually giving a thumbs up. I think people take it personally when a tuner gets more power out of something someone else couldn't. Should've seen what people said when I got a PowerFC as an ECU haha !

Might come down and watch on the 24th :)

not hating.

just saying that dont be disappointed when it doesnt run 130mph at the strip.

Also

esp is at 1800ft elevation and its summer.

so add 6% to that power figure for sea level conditions....makes it 390rwkws....

from -7s @23psi

but is wasnt the peak figure that made me say -5s it was the shape of the curve

not sure why everyone is on the defensive bandwagon lol isn't the whole point of a forum is to share info so we see what setups work for others, nice GTR much better track car than the 4 door :nyaanyaa:

Exactly,

I'm not trying to take anything away from James' car.

Id be happy to own it myself.

But when a dyno sheet pops up with 40kws more than every other -7 2.6 setup out there, and there are lots, there will be people who ask questions.

When I went searching for results for E85 on dash 7's I couldn't find any. Most peeps seem to go bigger, but they were already on the car so why not give it a crack.

Obviously I had it flex tuned and on 98 it made 300kw which seems normal. Perhaps -7's just respond well to E85.

As this was my old car I can confirm the -7's. The higher compression pistons probably help too. As for dynos when this car was running 98 it made 310kws at JEM and 296kws at ESP, so i belive it. Also wish I had gone the E85 route now....

Happy to see you looking after the car man.

Yeah but what we find here is arm chair experts that have never owned a GTR in their lives basing opinions on what they've read rather than real results.

It's not that different from results i had with -7s from a totally different workshop. I wasn't on E85 yet I had significant more work than most people with those turbos (head work, cams, 2.8 etc).

^^ Hey Shaun,

Well, I was told by ESP that the center diff, or is it transfer case, needs some love, (a change of fluids) and is causing the wobblieness on the graph, so maybe do both at once? haha

But really right now it is frighteningly quick as is. Very different car now. The E85 makes it come on boost a lot quicker and ramps harder.

Feel free if you want to come visit, and i'll take you for a spin.

James

    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
    • You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
