Ben has tried more than 5 turbo combos on this engine alone, while logging temps and pressures.

You would be amazed at the power some of these little turbos can make.

As far as I know the turbos are off the shelf -5's.

.64 turbine housing.

I'm glad you assume the compressors wont make that much power.....apparently it is actually the turbine that is getting close to the flow limit.

Same turbos on a F355 Ferrari also make over 450kw @ wheels on only 16psi (different dyno).....

My own track car with 2.6 engine and -5's makes over 400kw @ wheels on pump.

This engine is the culmination of 8 years of Race Pace RB development.

It was built as a challenge for a stock appearing/mannered engine to have monster power and response.

In the last 12 months it has seen over 10,000km of road use and various track/tarmac rally events and is still going strong.

I want it!

what a great read this thread was - educating myself on these larger capacity rb's is very interesting & now makes more sense why the r35gtr has gone the route of increasing cc's!

after reading this thread & talking to ben from racepace...he obviously knows his engines.

i may have missed it but is this engine in a gtr with the rb26 head?

john (JFKGTR) - did u get my pm :thumbsup:

Hardly something to compare to RPMGTR...your over 60rwkw short.

The thread is about big capacity RB's, he is contributing relevant data regarding a large capacity RB.

Ever heard the term STFU? :thumbsup:

Ever heard the term GFY.

Btw this thread is about RB29 Wow.

Btw this thread is about RB29 Wow.

And people reading about RB29 WOOOOWWWWW are here to say wowww look at the 2.9L go. Its perfectly relevant for someone else to give a comparison to a 3L, so that those reading this thread can make informed decisions about what they want to do with their own cars.

No need to be sour and say 'your 60kw short'. Crap like that is why there are 1000 RB30DETs on the road and only a handful of people willing to share their knowledge and experience.

Reading over this thread again really got me thinking on how Ben managed to get the results he did using pump 98 on such a low boost pressure.

You would be hard pressed even with E85 on a well sorted motor. To do it with 98 is an achievement in itself as the motor would need to be extremely knock resistant.

High(ish) comp with tricky chamber shaping would have a big part to play I think. I know its the package as a whole that makes it work but to achieve peak torque so low in the rev range and keeping it all the way over 8000rpm isnt as simple as a good exhaust/turbo combo etc.

Im sure even with a bigger turbo setup it would still blow anything out of the water response wise.

Anyone with some inside info want to share some knowledge? or is the answer going to be worth $50,000? :)

Seeing as the car with this engine is for sale, I might as well spill some of the 'Ben's secret specs'

Custom billet crankshaft 84mm stroke

Custom titanium rods

Custom forged pistons 86.5mm bore

Custom chamber/port shape

Variable cam timing

12 injectors

Thats the basics, Im sure there are lots more tricks in there.

I was reading about the new version of the HKS Vcam system last night. This is probably old technology for all I know...

http://www.nengun.com/hks/valcon-ii-rb26-v-cam-system

It seems like an easy way to go to get the wide power band without having to engineer your own VVT system. This setup, some step 1 springs and a ported head is looking to be the top end recipe for my next engine.

It's a bad comparison.

Clearly he came here to big note himself (why else would you thread dig)...

Read the 400kw thread for more details if you really wanna get into it.

Please read the thread in 400 kW.

I posted the link to get a reaction. Was not expecting a bad one.

I have no axe to grind, just want to share my experience on the best GTR forum in the world.

I guess the comparison I can make is I spent about $14,500, all work done by others.

I now have close to a brand new motor, new turbos. Surely this is valuable to others.

I had the opportunity to purchase a built bottom end from ben at racepace in 2009 but I missed out by 1 day. It was only advertised for a few days, he had high demand but then he sold racepace from what I heard?

Gasco123 - Greg at pro engines is a good guy as he ended up building my 3ltr and I too had very good results

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
