Did You Dyno Your R34 With Zorst Only?


Recommended Posts

What dyno was it?

On a Dyno logic one, I've seen an R34 GTX-T series 2 get 169rwkw running about 12psi, stock ECU and CES 3" Exhaust (split dumps), auto. A series one auto R34 GT-T with nothing but K&N panel filter, stock boost and an Apexi Cat-back 3" exhaust do 147rwkw. Neither car had front mounts.

Mine has more than just exhaust and boost so I won't post mine.

175.1rwkw with 3" turbo back exhaust & Just Jap 600x300 front mount.

Stock boost & computer, manual box.

edit - Mine seems a little high going by the above numbers... suppose it just comes down the dyno I suppose.... I'd like to think I have a heathy motor :)

Wow these are some high figures! I was only hoping to get about 170-180rwkw with turboback exhaust, fmic, 13psi and pod.

I just fitted a full exhaust on Sat and I must say the difference is huge. I'll see if I can get a dyno run in for you.

Managed to get 176rwkw with my stock turbo, but the timing was being pulled due to overboost retard. Had I realised exactly what was happeneing at the time would have been able to drop the boost and probably make more power.

Manual Box

3" Split dump/front, 3" Blitz cat back

Pod with heat sheild and standard snorkel

Standard ECU

Standard IC

Stock Boost

2 dyno runs with identical results - 168rwkw

From memory;

100% stock = 147 rwkw

Cat back = 168 rwkw (boost went up 1.5 psi)

Split dump and Magic cat = 183 rwkw (boost went up a little bit more, say 1 psi)

Standard R32GTR intercooler and my own design of 63 mm pipework = no dyno

Power FC, tune and boost up to 10 psi = 205 rwkw

GCG Ball bearing High Flow, 1.5 bar boost, tune + injectors = 248 rwkw

Tomei Poncams, 1.4 bar + tune = 265 rwkw

:) Cheers :laugh:

Yeah mine was the one with the Apexi cat back and panel filter pulling 147kw atw from a Dyno Logic dyno at our SAU dyno night. Apparently it was reading lower for everyone that had previously dynoed on a Dyno Dynamics...so as SK predicted...with catback...*should* read somewhere closer to 160 for stock with catback only?? :blink:

SK; is your motor stock standard?

Other that the mods above, I also ported it, then volume matched and polished the combustion chambers. I used a standard headgasket with o'rings around the combustion chambers. That's it for when I had it. I sold it 3 years ago, don't know what been done since.

:blink: cheers :)

Shhh n15m0; my car is stock.... :(

Anyways; got off the dyno on Friday with 225.31rwkw @ 10psi of boost... had a boost leak issue (will post up a proper thread about it later today).

Funny thing is that it shoots to 18psi by 4,500rpm - holds till 5,500rpm then slowly drops back to 10psi by 7,200rpm. 1 bar of boost was reached by 3,500rpm. Pulls like a motherF' when the boost kicks in; just not up high :/

New boost controller for me; and maybe some welding!

    • Vanos solenoid problems and basically all sensors die an early death 
    • Yep, back in the day when you could pick up a Stagea RB25 NEO for $1,500 it was worth it. These days... just chuck your V8 or B58 in.
    • from my limited BMW experience: - they burn oil WTF (B48 FTW 170kW engine) - dump oil every 5,000km and you'll be ok.. until it drops a bearing and rebuild time. replace engine with B58
    • I would avoid the AWD motor in a RWD using a modified RWD sump and pickup. The way the pick up is positioned, you'll have oil pick up issues on hard acceleration on a track around bends. Even with a baffled, gated sump. I suppose if you don't race on a track and it's used for straight line activities or street use you might be ok.
    • They absolutely are, but the thing is, if you're only exposed to these circuits for a while, what I normally think is good driving suddenly isn't so much. I was a pussy at the Nurburgring (GP) entering corners at 180kph - the difference in the balance of the car suddenly becomes so much more pronounced and I'm still a bit regarded at left-foot braking - something I now practice on my commute. So the (dream) plan with the E90 is to make it a 325i Cup car. Whether I get there or not is another matter. In my mind the simplicity of having the NA variant and cost made it a bit more appealing. Plus, like mentioned above, I'm actually too much of a pussy for big power. Of course I f**ked up by not researching enough on the N53 vs N52, the latter being more robust without the DI system.  Suspension-wise on the BMW, and I've been reading the technical requirements for the 325i cup, basically everything except struts has to be standard - bushes are free. I figure you get about 5-10mm adjustment with the rear camber bolts which should translate to 0.5- 1.5 degrees of adjustment. So with coilovers, lowered at 30/40mm I expect I can dial out some of the camber from a drop and attain -1.5 to -2. If necessary, I could get the same effect as the M3 arms with some offset bushes. There is a limitation on ARB width to qualify, although I absolutely want to get either M3 ARBs (can't say sway incase I upset GTSBoy) or the H&R ones - both of these are the cheapest options. Like mentioned, M3 arms are on the way and I should have them fitted within the next week. How are the BC Racing coilovers btw? Reviews are mixed but I think for me they would be fine; a friend of mine uses them on his R34 for track driving and has nothing bad to say. I'm looking at these or the ST coilovers (German brand, new to me) as prescriped the in Cup spec sheet. They're both similarly priced and offer camber adjustment. It's fine but it really upsets my OCD. I've got a couple of options for dialing out the rear camber and keeping my ill-fitting wheels: raise the rear a little bit, say 5mm, that should permit -2.5 camber or drop the front to restore that slight bias of more negative camber up front (not optimal with the roads here). The next alignment won't be until at least next year and I really need to rebuild the rear subframe. For now, I'm not using it at all on the streets except occasional blasts through the German countryside. I was covering about 10k kms p/year in Japan, I expect this to now be about 3-4k. You could say buy better sized wheels, and yes, I should have. But the wheels came from the Z and price of good wheels is just insane now. Again, a couple of options: get a new set (I want 17" RPF1s) or buy two used 9.5J TEs, both are about the same price excluding shipping.
