Yer sorry buddy. It is the maximum, but is done by many R33's. -+10rwkw appears to be a good figure to go by. Average was a bad choice of word. EDIT: Well maybe not +10rwkw.. lol

It is one complete attached core but contains 2 rows. Have a good look, either that or you've been ripped.

Munna, That is a higher than average figure for those mods on the usual Sydney, Adelaide, Melbourne, QLD Dyno's. 195rwkw is usually (many many r33's) done with 11psi, powerfc, exhaust, fmic. Your mods generally get around 180rwkw. But that being said 15rwkw is well within the dyno variation.

StockyMcStock. I know of a RB30DET making around 320rwkw using a GT35R .82. That only just makes 1 bar by 3500rpm on the road accelerting as you would in gear, by 4000rpm it will make any boost you throw at it. Big exhaust a/r's scare me. I think the Rb20DET mentally scard me. Comparing a/r's doesn't give the same result. For example a .82 GT35R creates the same amount as back pressure and flows the same as a 1.06 GT30R. Imagine a 1.06 GT35R. I guess all you can do is select the exhaust a/r to match the power output. My thinking is its no good going a GT35R 1.06 rated to flow 700hp when you are only going to use 500-600hp. A GT35R .82 apparently flows 620hp where the GT35R .62 apparently flows 550hp or just over 500hp, I forget the exact figure.

Its clear the average power made from a rb25 turbo on a rb25 is around 200rwkw. They can be squeezed to 210rwkw. On the rb20det the rb25 turbo should make close to 190rwkw, the rb20det runs more boost than the rb25 obviously.

My R32 GTS-T radiator is a 2core. My understanding is the GTR radiator is the same. Only the Silvia's got the single core.

It was the .82 a/r. The specs are some where in the damn long thread, I rememeber the total power made was somewhere around the 250rwkw mark, which sounds a little low when I've also heard of them topping around 300rwkw. Do you think the SB8006 should be able to keep up 1.06? With the GT30 I don't think it was the compressor side of things causing a problem, I think it was more so the exhaust side dropping VE.

Lag time correct? This apparently has an affect one how well the O2 sensor controls the afr's in closed loop mode.

I need to know. It could be an alternative to the GT35R. The GT35R may be a little too big for what I want. The GT30's tend to flatten out the top end over 5000rpm.

I think your confused with Skylines Downunder.

Do you mind posting the dyno charts & Injector size & injector duty cycle at peak power?

Does it look like the 10cm housing Troy?

I'm starting to really like these TD06 turbo's. Where was peak power made?

Yer not sure on the fuel economy, A couple of things I can think of?!? Accelerating around slowly and boost starts to build I lick the throttle back a little to let the BOV bleed the boost. RB20 general driving I used to change up at around 3000rpm. RB30, I change up just over 2000rpm, some times i throw it in a high gear and let the torque lug slowly to the speed limit. What injectors are you running? Spray patterns and good atomisation make a noticable difference to economy.

RB30-Power, Have you had it tuned? My ECU really didn't like running boost. Mine played up big time, big power dips. Without boost or very minimal. It was fine. The PowerFC was much better. The Ignition was to aggressive, fueling was fairly close.

Looks very nice Dave.

It will be fine. IF its tuned well. The only reliability issue could be the N/A has no oil squirters to help remove heat from the pistons. RB30ET's dont run piston oil squirters so in practice it probably isn't an issue for moderate power levels. If compression was an issue throw in a thicker head gasket. Thats not difficult, especially if done before the motor is dropped in.

lol... There was bugger all room in the dyno room. It was either the passenger door, the front guard or the rear wheel.

Unlike the rb20det it makes a difference if I boost it around everywhere. The RB20DET would always get 470km's to a tank of juice. The RB30DET if heavy with the foot will get a minimum of 430 and a best of 520 with a light cruising foot.

I too cruise around at 50km/h in 5th. Put the foot down a little boost comes up quick and accelerates away easily. Since the new motor I also find my self pulling out of corners/round abouts in third and fourth from as low as 1000rpm. I've always dropped it in fifth when cruising at a steady speed. If I need to accelerate, drop it back a cog. Maybe this is why I used to get 470km's to a tank of juice (50l) with the rb30det and recently managed 520km's from the rb30det?

Limited space in the dyno room. Mr. Darren. At the time of taking the vid I was actually watching for any little bits of detonation. Little white puff of smoke.

hehe he had no choice, knock levels were reading too high. I don't know Shaun personally but have known of him for quite a few years now, he has tuned quite a few high powered RB's and to date, touch wood, hasn't popped any. He does get good power out of them also so he does have a nack with tuning.

It hits .1v higher, now 4.1v. Prior to the tune the most I saw was 4v. Previously I wasn't reving it out, changing up around 3500rpm. The stock AFM was hitting 4.98v. So basically the Z32 drops voltage by 1v at those airflow levels. Standard cruise and idle airflow voltages appear to be the same if not very very similiar. One thing I have noticed is with the Z32 it tends to idle and cruise slightly richer. With the stock AFM it was dead on 14.7:1 both cruise and idle. Now it tends to sit on 14.2:1 on idle and 13.9-14:1 on cruise, I'm unsure if this small amount will affect fuel economy. It could be my O2 sensor has decided to kick the bucket as I've fitted the Z32 afm.

I popped out to grab some fried rice for tea. lol Thats my excuse anyhow. For those interestered. Boot down up to 4850rpm saw 90% duty cycle, 4.1v on the Z32 AFM and 13 knock. She broke traction all the way through second twisting the car around when I came off the throttle to grab the next gear. It definitely has some torque. Alf.. That flamin' Alf Fisher avtar is shocking.. lol

Shaun did say he had to pull a heap of timing out of the top end, small turbo. Lots of backpressure which may have caused reversion then detonation.
