STATUS Posted March 11, 2013 Share Posted March 11, 2013 That first one (if it was usmair or whatever), didn't come close to the MPH to back it up, in fact the MPH showed it has zero gain, where the "dyno" said there was 40rwkw... I'd like to see Trent's result hit the strip and pump out a MPH. As with a few other people on here actually... It seems some have pretty "hefty" increases that seem to defy what everyone else are getting. (not having a go at anyone here either, just wanna see more info). tbh i retune around 3 e85 cars a week from other shops (please understand i dont mean all just some) and tbh some tuners still dont understand E85, we generally get a gain every time. we dont do drag cars (i have 0 intrest in drag) but EVERYTIME the owner will better their PB at any given circuit track. 70-80% of our tuning is now e85 so we live and breath it daily, some cars dont get the benefits but many do, the cars that do are the ones limited on 98 by a fundamental element not turbo sizing and -7's fall smack bang in this category. S15 are another good example 220rwkw on the std turbo up from 195rwkw is a common result.... normally restricted by a so called too small a turbo.... 11% increase on such a small output is super impressive. Generally a GTR making 310-315 will always make 340-350 on e85 with no increase in boost if tuned correctly (providing there are no intake or exhaust bottlenecks). The basic rule of this extra power is the same rules that gain power on 98. i know we are getting legit results just by the numbers in the mapping, anyone who understands the fuel will know what im referring too. Ash im happy to show you in person where these other tunes are falling short. i have all the saved maps from the cars im referring too. Also if anyone is not getting the results they should im more than happy to view their ecu file and give feedback on why they havent got the results.

Buraz Posted March 11, 2013 Share Posted March 11, 2013 what setup and ecu?Runs a power fc, -5's, built engine, full exhaust, fuel system etc. All supporting mods really, I can't think of anything major its missing. This was on a dyno dynamics. To be honest it feels way more than 12kw increase, it's a beast now I'm happy with it (except from blowing the gearbox last night) I just find some other results are much higher.

usmair Posted March 11, 2013 Share Posted March 11, 2013 Just an update on mine... -9s on e85 when I took it to the strip and ran 11.7 it had a pretty big boost leak this was confirmed when I took it Unigroup's dyno day and I make 315kw (on a hot day). Yavuz said on a cool day it would make around 330kw. He also confirmed that there was definitely a boost leak somewhere. I put on hard pipe kit on (did it myself) but there is still a leak. I took it to PowerTune on saturday to see if it made a difference. We did 3 power runs... all three made 332-335kw (this was the same dyno that gave me the 370kw reading). so i think the unigroup vs powertune numbers are comparable. There is a big screech and a boost leak. the dyno shows boost dropping from 24 to 22psi. I've left the car with PowerTune and they will fix the leak hopefully this week. Then its back to WSID!!

Hadouken Posted March 11, 2013 Share Posted March 11, 2013 I agree with your comment of 310kw to 340kw. But 310 to a increase of 370 is huge for a same boost application Link to comment https://www.sau.com.au/forums/topic/403940-getting-more-power-out-of-7s/page/4/#findComment-6779264 Share on other sites More sharing options...

But 310 to a increase of 370 is huge for a same boost application Its not the same its running more boost 18psi on pump 98 vs 22psi on e85. i also stated anything over 22psi netted no more peak power.

JimmyRickard Posted March 13, 2013 Author Share Posted March 13, 2013 How reliable is United's E85? Is it a bad idea to base a tune on just their fuel? And just to be clear, is 370rwkw achievable with my setup?

Mick_o Posted March 13, 2013 Share Posted March 13, 2013 Any E85 is reliable mate tune your car to the fuel you use. I tuned my car with the caltex E85 & my car has never missed a beat! Dunno if this is true or not but I think caltex has more servos selling this stuff so id be more inclined to tune on that stuff as its more readily available. As for 370kw on -7's id say not likely at all I would think even -9's on E85 would struggle to hit 370kw Link to comment https://www.sau.com.au/forums/topic/403940-getting-more-power-out-of-7s/page/4/#findComment-6781884 Share on other sites More sharing options...

Mick_o Posted March 13, 2013 Share Posted March 13, 2013 Just tune for E70 as that's generally what it is all year round but that's something for your tuner to sort out. Well I stand to be corrected if there is 370kw -7 setups out there lol Link to comment https://www.sau.com.au/forums/topic/403940-getting-more-power-out-of-7s/page/4/#findComment-6781926 Share on other sites More sharing options...

Hadouken Posted March 13, 2013 Share Posted March 13, 2013 Because it wont just be 85% ethanol. It will more than likely range from 70-85 just like what the sign on the bowser.
