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!
