So I dropped my car off at Advan about 8pm on Monday, arriving almost immediately from Melbourne after a great 2,500 kms of virtually fault free, very spirited driving on straight 98 pump with 315kws. I filled the car with E85 before I dropped her off and the next morning, the EOS PI kit, stage 3 fuel pump and N20 TMAP sensor we hooked up.

The first car in Australia to run Hexon RR700s and 100% E85 pulled an awesome 412kw atw!

Ok, so there was nearly 5 litres of 98 pump left in the tank, so that would make it approx E79.

I'm pretty chuffed to be in the 400kw club, but honestly, anyone who's gonna run upgraded turbos, PI and 100% E85 should get there easily. I know Justin said these won't be Pure Stage 2 killers, but I was kind of hoping for more. Pushing him to try and extract a bit more so I can temporarily take title of most powerful 335i in Australia until someone with Pures goes all out, but it looks like Marty will keep it for now with his 422(?)kws!

I know American dynos run higher numbers and our fuel quality may be different to theirs, but how Ken Wedge managed to pull 500kws, I was hoping for around 425kws.

Justin smsed me the dyno results and I haven't really asked for more details on the tune, boost, WGDG, AFRs etc, but will get those later. He says there's not much left in the turbos.

I wonder if an extra 5 litres of E85 will make much difference at all and will be keen to see the United fuel quality after my E85 content analyzer gets hooked up!

All in all, nearly a 100kw gain from E85 makes me pretty happy and once my upgraded chromoly Driveshaft Shop axles arrive, I'll be installing them along with the MFactory LSD I purchased nerly 18 months ago along with a diff lockdown kit and hit the drags to claim world's fastest E93!

I've never been to the drags before, so it will be a huge learning curve for me and I wouldn't hold your breath for amazing times until I get 10 to 20 runs under my belt maybe!

Overall extremely happy with how the RR700s performed during my drives in Melbourne and the responsiveness they provide. Yes, there is a bit of lag under 3,000rpm but when pushed, power delivery is very linear.

Soon, my car will be off to the panel beaters for a while to fix the damage sustained from hitting a Kangaroo on the way to Melbourne! It may take a while to get back on the road as I have to wait for another 1M front bar to arrive from overseas and get insurance to approve it, but once I do, I gladly welcome any of the forum regulars to have a drive of my car if they are considering upgraded turbos!

Damn app doesn't like uploading photos. Will try imgur

[JB4-335]

Nice. Well done.

Do you have a log of the dyno run?

[Coupes33]

Congratulations on achieving 400+rwkw. How much torque is it producing? The torque curve from the dyno would be good to see.

[tawfeeqh]

Well done mate great results! Can't imagine how it would drive.

American dynojets are very high reading compared to the Aussie Dyno Dynamics and Mainline dynos. From your chart you are peaking at 25 psi. Ken was running his turbos to 27-28psi, but if Justin says there is not much left in them probably no point in pushing them any further.

I remember seeing the 600s on the Hills mainline making around 360rwkw on e60 with Kens flash only. He was also peaking at 26-27 psi I think. I guess its not just about boost, but also "timing" advance and how many degrees being run. Two different tuners (Tribela, Wedge) may have slightly different approaches. Also your car is JB4 with backend e85, Ken's was straight flash controlling PI through Haltech P1000. There is always debate from the tuners on whats better/ worse i'm certainly not a tuner so not in a position to comment, however there may not be a lot of difference in peak power running either setup who knows.

Would be interested in seeing your logs and your AFRs and WGDC as well as lpfp and hpfp.

Anyways good luck with the rest of your build. This is surely the most powerful and meanest convertable bmw in Aus - take that crown lol

[bradsm87]

That is an excellent result. The 5% extra ethanol will make no difference. I wouldn't push it harder.

Don't worry about american dynos. They output lies!

[tawfeeqh]

This was a pure stage 2 on a mainline dyno in Melbourne. I believe it was running around 25psi too also tuned by Tribela. Can't really compare as two different cars and two different dynos but at least you have some reference. Also not sure if there was still room for more power with these.

[R32GOJIRA]

Dude that is a wicked result.
Gotta make you feel a little better after hitting that roo.
Looking forward to seeing what you can do with it on the strip.
Good luck

[DR-JEKL]

Well done Kent, great to see your car putting out some great numbers!

I bet she feels like a weapon now, I know my car feels great on the highway etc with a lot of torque with only a mere 316 rwkw and what ever torque she's putting out...

That boost curve looks a bit funky whats going on there?

[_ink]

Awesome result Kent! You should definitely be happy with that result.

The logs are really important mate, more so than the dyno chart imo.

Marty's car is manual, so less valve train loss mate. Also, the octane benefits of ethanol max out at e60, so I don't see the bump up to e85 from e79 doing much in added power.

This is a phenomenal result on your auto transmission Kent, be happy and soak it up!

[Socket]

Nice work Cashy awesome results... RR700 FTW

[AYEDEE]

Great to hear that the car ran well. As for that kangaroo i hope you were on Full boost !

Would meth injection get him more power or is the same issue?

[E85 335]

Awesome results. Well once I get mine back next week I will throw it on the dyno once i have the tune done and we can compare results of Pure's vs Hexons. I am excited to see that people are making huge power with their setups.

sorry bud I only made 413rwk so far at 23psi

Still have other issues to sort out

I was actually there when the car was getting tuned, meth would not have helped

They let the car cool down and tried rerunning it and made the same.

Looks like the turbos may be maxed out.

[tawfeeqh]

Which RBs are you running again marty? std RBs or stealths, if you dont mind me asking. You reckon you will cross 420rwkw when all your stuff is sorted?

Need to see logs

[kOncept]

Congrats, great results!

I'm not sure how accurate this tool is but it may help you compare DD vs Dynojet figures.

http://mkiv.supras.org.nz/dyno.htm

According to that calculator 500rwkw on a Dynojet is roughly 420rwkw on a DD so you're not far from your expected figure.

[bradsm87]

There is no issue and meth would not likely add power at all due to the already very high concerntration of E85 and PI. It's an epically high power figure and the turbine wheel which is smaller than that of standard RBs is absolutely maxed.

The high reading American dynos just give Australians way too high expectations.

[E85 335]

100% Meth injection pre intercooler will make a difference. Thats what I will be running.

I really don't understand how there can be such a big variance between dynos makes no sense we are talking over 10% difference.

maybe someone can explain to me??? : which dyno is correct the higher or lower reading one? I mean power is measured in a standard unit of measure (Watt) so either you're making said quantity of power or you're not....
