Interesting to note the SR22VET is superior on all accounts. Its over half a litre smaller.

It goes to show that cylinder head technology pays out a lot more than cubes.

I think there is more to it than that - compare it with similar sized smaller and "higher performance" wheels to an HKS T04Z, and even the larger (and older tech) HKS T51R Kai on an RB28 running pump gas: kaibb%26%2Bto4z%2Bpower.jpg

Going by that, a T04Z spools better than both turbos - and a T51R Kai is not far off them at all.

Regardless, yeah - SR22VET is way up there in terms of efficiency, while RBs are not so much... by todays standards.

The head on Ninos's engine is top shelf and costs more $$ than what most people are prepared to pay, hence a nice result. That and his engine is a result of endless testing by Advance Motor mechanics and associated companies/people.

Its is all about combo rather than bolting on an "awesome" turbo and expecting to get the same results as others.

Glad to see we agree.

I was not implying the VET head alone is all the difference, but the technology implemented in that cylinder head is clearly a winner. That means both the factory VET side of things and the work the said firms have put towards it.

Lith when I look at those graphs I still see that the RB28 you posted is behind. I typically look for the point where the incline starts to nose over and I consider that to be the point where the motor has hit its threshold. The said VET is hitting that point at 4,700 whereas the RB28 you posted is 5100 on one of the turbos and 5500 on the other.

Obviously there are only hundreds of RPM in it for vastly older tech turbos but I think it notable to consider the big difference in capacity between the two motors. Plus, my comments were actually specific to the two results shown rather than general. I am more than confident that we can find a VET result which is shadowed by an RB.

Agree Ninos engine is sensational and I'm expecting similar results with mine but isn't that RB28 on 93 octane? If so then not really a like for like comparison or even comparable IMO.

Those turbos on 93 octane are not going to perform anywhere there capability on any engine let alone that one.

Yeah definitely, the thing that really does impress me about it is that power is huge for a 64mm compressor on pump gas - I reckon. I'm not sold on the power delivery, though - I think there are competitors which would do that with better delivery at this stage.

Went out again last night with new suspension, looking forward to a prepped track and getting the car to hook up. Ran a PB on lower trap speed and a slower 60ft so that's a good start! 2730lb, only thing removed was the passenger seat and side pipe fitted. Looking forward to get this thing to hook up so we can tap out the 7175!

Different angle with incar

    • 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.
