Quoted Lith because he loves a oil leaking precision... 9.609 @ 146.10mph last night at the drags

Not bad for the baby 62mm, only got one pass and then got the boot

Yes..

 A rather mysterious Piglet has been keeping me up to date on the bacon you've been making. Absolutely huge effort - I am blown away... There is so much to be impressed with in regards to that result.

How confident are you that the same parts list you have would achieve the sake results?

I think that anyone could do it with the right knowledge and skills, but it's not a simple slap on a 6262 and do a 9.6

Yeah obviously - though the power to pull high 140mph trap speeds is no joke!   Funny, I was reading a thread with someone running a 6466 on a Supra and "on kill" they ran a few mid/high 9s at high 140mph traps before snapping a turbine shaft.  Your 6262 is punching high!

Here's a 6266CEA on my 30DET @ 24psi, held across 4200-7200rpm.  All basic build stuff, engine included.  8.4:1 CR, 265 degree 8.9mm fixed cams. Single scroll 0.84A/R on a 6boost manifold, 50mm gate plumbed back.  Running on petrol.

Timing scatter is currently an issue, did impact on tune/output so there's gains simply from fixing that (in progress now before the next event)

RB26 Head?  Will you be getting an E85 tune?  Looks like it's holding power quite well to redline currently, will be interesting to see it does with more stable triggering.   There is an outfit in NZ who do a very affordable cam trigger setup (but not using the flimsy stock Nissan drive) which fixes this kind of thing with the stock cam angle sensor configuration without going 10/10ths on a crank trigger setup, if you haven't gone there yet and were wanting a reliable trigger setup without going 4 digit costs.

No, just a 25 head with hydraulic lifters and upgraded springs + minor exhaust port adjustments.  The whole thing is loafing along, quite a bit more to extract if desired.

We'll resolve the triggering prior to the next event at end of May, and get it on the rollers at some stage just to validate the improvement.  Going with the cam trigger setup you mention, interested to see the difference in timing logs.

Probably staying with petrol at this point simply because it's not short on stick for what I need the car to do.  And I avoid the inevitable need to go with further fuel system upgrades.  Money better spent on tyres/event entry and actual seat time :)

Quick run on the dyno today just to have look at things, no tuning has been done with this turbo setup but was previously tuned with an unknown high flow on 14psi.

Currently does not have the  boost controller plumbed up and has 14psi gate pressure with a turbosmart 50mm on a 6boost manifold and 5862 turbo.

The dyno graph shows rpm about 300rpm different to last time it was on there, makes it look a bit laggy but it feels not that much different down low from the high flow and is a completely  different car now through the mid range and up top. Currently has 11 degrees of timing from 4500 rpm and up at 18psi.

Its given me a bit of motivation to get the new motor together and  get it on e85 and turn it up

Not a Skyline but this is a street engine RB26 (BC 2.8L Stroker kit) with a TH400 box, made 915whp through the auto and 1070whp through a manual on 35psi with a Precision 8285 (1.12 A/R) - sounds better than a mangmang. 

Cranked it to 40psi next meeting and cracked the factory block like a spider web, the car sadly hit the wall hard.

 

Also as a veteran of this thread I'm putting my PTE knowledge to a bit more use these days, I can help out any SAU Members interested in ordering Precision Turbochargers off my website.

Its on a Forged RB30, ported head Tomei 272's E85 

I like the turbo so far good response for what it is and it seems to make decent power.. Cant beat it for the money..

I sold my Precision after Precision rebuilt it and bought 2 Borg warners!! haha

Nice - any more specifics?  Been quite curious about the SX-E turbos and a few RBs seem to have them but no dyno sheets or hardly even any numbers, yours included now haha

    • 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.
