R.I.P.S NZ

Looking back I did 1.39 in the drag-r at 1740kg on ET streets so Meremere's not toooo bad off the line I suppose, its the rest of the roller coaster ride and the bumps and lack of top end grip thats the problem, Reece runs 3-4 10th quicker in Aussie easy, he told me I'd be shocked how much power you can use from 1/2 track compared with here. On the aborted 9.7 run in the drag-r I had 5.something @ 117mph at 1/2 track and that car has gone on to run 9.4 @ 155mph on a pretty average air frield runway so you'd have to be talking 9.40-9.50 with 6.0 @ 114??? Rob

Not much of a de stroke if its 2935cc, are you sure thats right and you sure it fits? Rob

RB30.

Man you guys have well prepped tracks, very jealous indeed, well done on the pic mate, looks great, what 60s did you manage? Edit, just saw you'd done 1.37, not to shabby at all :-) Rob

Lol, your the pretty boy!! I don't think 1051awhp @ 1.9 bar without NOS is too bad??? Rob the Fag

It made 1051whp at 1.9 bar but we ran out of fuel supply so we backed the boost off a little and gave at a 75hp shot of NOS which probably gave us a little over 1051whp. The trusty slide rule says we needed 1100whp to run 155mph in 1740kg so it was probably around there with the nos I spose. Rob

We took all the 6 port kit off because people thought it was the only reason we went any good, lol. Truth is, we never did try it and we did go quicker once it was all removed, wether it had anything to do with the removal of the foggers or just the other changes we made after then, who knows. Rob

My 240z RB30 engine has stock used mains bolts so its pretty safe to say that studs are absolutly NOT needed.

A 26 head won't go straight onto a R33 RB25 block but it will on a R32 RB25 so check it all out properly before you get carried away. Rob

The head is located with the 2 dowels, no need for sleeves over the 11mm studs.

Normal RB25 11mm ARP head studs, don't bother messing with the block, its totally un neccessary even if you want to use a 26 head. Rob

Update on this car: 1200+whp, C16, 7.86 @ 177.4mph Worlds quickest and fastest 240z and RB30.

Update on this car. Changed to Q16, 1051whp @ 1.9 bar, no NOS. Ran 9.4 @ 155mph with a 1.5 60ft on a very slippery track TOTB8 in the UK still at 1740kg. Possibly the quickest/fastest full weight + street R34 in the world?? Rob

Mmmmmmmm, not sure about that mate, we've done back to back dyno runs in 4th and 5th gear and got almost identicle power curves, within 3-5whp or so. Rob

What a trip!!! Had a fantastic time. The owner of the Blue R34 GTR (Drag-r) invited me to come and have a drive at this years event after he won his class last year on his first ever outing in it. We went a week ahead so we could check over the car, go on the dyno and check the tune etc. With no changes other than going to Q16 from C16, we made 1051whp at 1.9 bar no NOS and then ran out of fuel supply, it turns out the fuel pumps wern't rated to quite what we thought once running at the pressures we needed them at. We did the best with what we had and headed off to TOTB the day before the meet to get through scrutineering etc, all passed no problem and we were entered in the street class. Somehow on the day, the organisers decided I was a Pro driver (which obviously I am not) and they put me in the Pro Class against some very serious and expensive machines, there's money over there like you wouldn't believe and some teams had big artic trucks, massive crews and were extreemly well set up indeed, we didn't even have a ground mat, umbrella or a chair to our name, lol. Race day turned out to be drizzly and the old runway surface at Elvington didn't look like it was ready to hand out good time slips unfortunatly, the general consensus was we'd be very lucky to run a 9, let alone beat our 9.7 time I did on my one and only run in NZ. My first run of the day was a 9.97 @ 145 mph and boy was it slippery but a 9 was already in the bag!! 2nd run, much the same 9.94 @ 144mph then it started to dry out a little, by now I had the hang of the sequential shifter and was ready to do a standing km run. They time the 1/4 mile and then you carry on to the 1km mark, 9.61 @ 144mph and on to 191mph on the km absolutly smoking the tyres. It turns out they had prepped the 400 meters for the drags but not from then on so once I crossed the finish line of the 1/4 mile and got onto the hardly used part of the runway it started to wheelspin and smoke was pouring off the tyres all the way to the 1km mark, great fun spinning all 4 tyres at over 300kph but it had to have slowed us down a fair bit. Here's a video of it: After qualifying we were doing really well. Best time of the day was in the street class (Mega $$ Pro class subaru on dot tyres (same as us) but they let him stay in street) with a 9.44 @ 150mph and in the Pro class the best was a 9.5 @ around 150mph. 1st round of racing we netted a 9.47 @ 147mph and then went on to run a 9.46 @ 155mph winning both rounds, both on a reasonably dry track. Had a buy in the semi final, it was really wet so decided to just do a 6th gear burnout the whole 1/4 mile, lol, here's the vid, turn up the sound: The final was also wet and the other guy had wet weather tyres on so I decided to not even race, it was too dangerous and it wasn't my car, I let him go and just went out and had some fun doing skids up the track again. So all in all a great day, got 2nd in the Pro Class and the following overall results out of around 200 entries: Quickest 60ft overall with a 1.48 Quickest Pro Class 1/4 mile with 9.46 2nd Quickest overall 1/4 mile time, best time of the day Ole Clarkson's subaru 9.44 Fastest Pro Class 1/4 mile speed with 155mph (251.1kph) Fastest overall 1/4 mile speed with 155mph (251.1kph) Fastest overall top speed in the standing km with 191mph (309.42kph) damp track Vehicle weight was also confirmed at the previous meeting at Santa pod as 1740kg so probably the heaviest car there too!! I'd like to thank Jason from Infomotive, Link, Jeff Ludgate (car owner), Sparks, Robin and everyone else who helped or supported us. Rob

Cleaned, crack tested, no knife edging or lightening etc, just a oil pump drive and balancing, so stock as in not an aftermarket billet or knife edged or lighted crank, just as pretty much everyone else runs their RB30 cranks, nothing special about it at all. Rob

18-20psi and 7500rpm straight away and full power rpm within 500-750km max with 2 oil changes. IMO more boost is more important than more rpm but 10psi and 5000rpm is being real soft on it. I'd have had a basic mineral oil in there too and only go to full synthetic well AFTER you have done full power mapping. Rob

There will be a reason you bent a rod and I'd be pretty sure you had a dud rod or another issue all together. A friend has a RB30 with stock rods in a track gtst, he runs well over 500wkw/8000rpm and its been going for a very long time. I still maintain that stock parts are incredibly durable if everything is setup and tuned properly and its highly unlikely you'd be hurting parts from power alone, there will surely be other factors. My 240z engine with a totally stock, unfilled, non braced 2wd RB30 block with a stock crank running around 1400hp, 9500-10,000 rpm is WAY beyond what I was told by everyone was possible yet with extreemly carefull setup and tune it has been reliable and we intend to push them alot further yet with the ultimate goal being a 6 and 200mph on the same old stock block and crank and I genuinley think we'll do it. Rob

7 years, 1.5 bar + 100hp NOS, 450wkw with nos, low 10s, 7200rpm limit, stock bottom end with new rings and bearings only. the power your after is effortless on stock pistons, its all in the tune.

Well done Marko, glad she's all up and running, I nearly had to buy more memory for my computer to cope with all your e-mails, lol. Don't be too gentle on the motor mate, the first 500k's are the most important. Rob

Based on what? The worlds most powerfull, quickest and fastest RB30 uses Argo so they must be plenty good enough I'd say.

The 240z race weight was 1277.5kg as it was REALLY over built when they did the rear end, lots of thick heavy box section in the rear. The new car which is getting the 240z motor is quite a bit lighter so hopefully we'll get the times down some more and keep the Aussie's (who are obviously on the way) at bay Rob

Just to clarify a few points. I agree with the above guys, there is absolutly no point in revving the enigne to 9000rpm unless your still making good power at that point, you will probably find your motor will be falling away at around 7800-8000rpm. The RB30 in the 240z has a stock crank (with our mods) stock cradle, stock mains bolts, perfect balancing, top class pistons and rods, normal tomei pump, normal wide type oil pump drive, RIPS wet sump and a world class cylinder head built to cope with 11,000-12,000rpm. We regularaly run 9000-9500rpm and power is still climbing at that point, we hit 10,000+ during the burnout at times and have seen over 11,000rpm over bumps or when sudden wheelspin has occured. Its not just a matter of putting the above parts together and its going to rev that high, I assure you there is ALOT more to it than that but with correct preperation, blueprinting and very anal assembly we have proven reliable at around 1400hp at those rpm levels. My advise would be keep the rpm as low as possible to get the power you want. Robbie.

RIPS RB30/26 streetable engine Stock RIPS prepped 2wd block, no filler or braces, fully water cooled. Stock RIPS prepped crank RIPS 2wd wet sump, tomei oil pump RIPS RB26 head, brand new with tomei parts RIPS inlet plenim with 90mm TB RIPS custom exhaust manifold GT45 turbo Twin turbosmart 50mm progates 75hp NOS kit 1200whp @ 9000rpm, 2.1 bar on C16, 7.86 @ 177.4mph

All depends what turbo your using as to how much boost you could run, 2 bar with a GT45 is obviously going to be different to 2 bar with a TD05. 600-700hp at around 7000rpm can be reliable if its setup and tuned correctly but we have had one customer with a GT42 with C16 run 1.8 bar for quite some time (around 850hp) then wind it up to 2 bar where it cracked a ring land on 1 piston only, he's unsure why.
