Hiya, I just installed my autometer boost guage, was about to install my turbosmart bleed valuve but I noticed that I'm alreayd hitting 10-11 psi in 4th at about 5000rpm now I thought r33 stock was like 7 psi from what I know my car is pretty much stock just had apexi dunk exhaust and K&N pod filter. is this normal.

like 1-2 are only boosting at like 7psi but soon as I hit 4000+ in 3rd or 4th its str8 up to 10-11 psi

could I have installed guage wrong or is this normal?

whats your std guage readin?

it does sound a little high for only exhaust and filter. these will increase boost slightly as it allows the engine to breath easier do a search, the basic mods on R33s are fairly well documented. maybe this is what boost is achieved by doin the exhaust and filter

would make sense seeing as last time i went to the dyno the guy said it was running at 10psi which was a little weird considering at the time i had no mods other than the cat back thats on it.

my car runs 7psi up to 5000rpm then over that it hits 10psi. I have a remapped std computer by selection, and I think its this that has changed it. Pull out your ecu and look for stickers on back side etc, as it could have been done in jap.

nark - put boost gauge on a stock r32 the other day and got 10psi too.. maybe 32's run 10psi stock?

maybe it does dAVE still waiting for my cupholder to come in... they were sold out when i went in on friday which pissed me off cause i wanted to have it in on the weekend.

will install it this week and have a look... the one the car has in the cluster doesnt work at all... maybe there was an aftermarket one installed originally and they took it out when they sold it??

either way its running pretty well :D

This is the standard setup for a stock R33. There is a "flutter" valve that is commanded open by the ECU when you get to 4500-5000 rpm. This bleeds air from the wastegate control line. Less pressure in the line => wastgate not open as much => more boost.

    • 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.
