i dynoed my 33 gtst today and got 207.2 hp @150kph and 837nm @130kph ,@9 psi

Mods are fmic ,safc,pod filter

Also found out that the exhuast is stuffed cause when dynod at 11psi it produced 203hp so i need to get a 3inch and i should be able to get 220hp at 12psi.

Anyone else got a read out with the same mods???Is this a good read out???

yeah... more to the effort than the actual amount!

Did you wind the boost to 9psi ?

cause one you do the zorst... you should have 9psi without dialing in anymore.

Just cause it's more flowing and the turb's won't be spinning as hard due to less restrictive exhaust.

Running more boost on a restrictive exhaust will have the negative effect you noted.

make sure it's turbo back though. the most important part in my opinion is the dump pipe. Allows the turb's to spin way more freely.

I dynoed it at ATS ,Yeah i sounded pretty low to but its a auto and theres more off a loss through the drivetrain then a manual.Does anybody no the exact amount of power u lose through the drive train??Also i just spoke to ats and they said they can make a 3inch exhaust mandrel bent from turbo back tig welded with hi flow cat +muffler for $1100.And it should go heaps better ,i looked at the cat and u cant even see through it !!also the middle muffler has broken up .Most skyline's run rich yet mine was leaning out due to poor airflow .If i can put done 250hp when im finished with more boost and a good tune ill be happy,if not then ill have to just put a microtech and T04.lol

I got my car dyno'd this week and it reached a max of 175.1hp.

The line on the graph stoped at 5500rpm, I cant remember what run this was, but the car was hitting boost cut all the time.

I'll try and attach a scanned image of it when I go to gf place later so someone can explain if my car is running ok or not.

Mark

spoke to him again and he explained that the calabration on the a/f sensor was out cause i have a 6inch dump pipe and two much of the exhaust gas gets around it???And that the standard settings where even leaner ??i dont no but he did tune it for cruising more than power ,And they have been working on turbo cars for like 20years .Ill see how it is after the exhaust is on and post the dyno sheet up.Also about the torque i think its traction too cause i thought 837nm is alot of torque for any low mod car.

    • For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?
    • 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.
