All bleed style boost controllers suffer from this problem. we have also found that boost drops off in top gear. Best way to solve this problem is to install Turbosmart E'Boost. E'Boost 1 is on special for $600 as new E'Boost has been released. They work prime with no spiking or boost bleed.

Mate, honestly I wouldn't even bother with a bleed valve. They all spike and suffer when trying to hold boost up the top of the rev range. Save your pennies and get a Turbo Smart E-Boost. They're on super sale at the moment for $600.00.

Remove the faulty bleed in the mean time.

yeh i was looking at them...they look pretty neat and have heaps of functions hey.

They have heaps of safety features which eliminate overboost, as well as excellent wastegate controll. you can keep gate closed for longer which brings boost on harder & faster. there are also outputs for launch control or N.O.S etc

Hey

what type of bleed valve do you have at the moment, so we no to stay clear of it :D ???

BTW is there a electronic boost controller.. that doesnt have heaps of functions and is realy cheap ? Paying like $400-600 for a boost controller is like half the cost of an ecu :rofl:

I've just picked my self up a cheapo ball and spring type bleeder. Its not actually a bleeder, the knob adjusts the tension held on the ball.

Should work well as I've had a similiar type before which worked really nice.

its a TURBOXS boost controller, from SPEEDWORKS.....hey ZYMOTIC do you recon that boost controller is quality or dodgy???

Don't they have a little allen key in them to adjust spike?It may pay to have a look and if it does have a fiddle.

All styles of bleed valve are ugly. We are a turbosmart agent, there product is good but still suffers from boost spike. its just how bleed valves work. Im not sure what type of ecu you can buy for $1000, but if it controls engine management & boost, i suggest you buy it. ive been selling Haltech & Microtech for three years & they require stand alone boost controllers as an addition. Apexi ecu have boost control features , but by the time you pay for it, then upgrade air flow meter, you are spending good money. Trust me, E;Boost controllers are worth every dollar. Customers i have sod them too were the same as you until they drove the car after i fitted it, they were very impressed,

check out the article on autospeed.com.au and do a search on 'audi boost', i think it is a norgen setup boost controller.... i have one on my car and it NEVER spikes and has a wastegate creep.. costs $100ish and works perfectlly!

Sounds like the go. How controllable is the wastegate, do you controll it with Ecu?

there are basically 2 knobs... the first controlls boost and the second controls creep... mine is under the bonnet but you can mount them in cabin if you like..

It takes a while to tune but once it is it controls boost perfectly. i have never had boost spike since..

If it works its all good, but you have too compare apples with apples. Boost spike & creep are most evident when you revue a dyno run or drag run through a data logger. you would probably be suprised with the results.

i also have to knobs, but they say one is for coarse boost increase and the other one is for fine boost increase????

maybe the fine one is for creep?

I have one the same as yours maccaz I dont have problems with boost spikes had it tuned at Ice Performance boost holds pretty well I run 10.5 pounds drops off to 9.5 by redline but Ice Performace said this is pretty good and even the electronic boost conrollers do that to a degree and yes they did tune the boost while on the dyno. They said Unless you have something like that (while pointing to GTR with a huge turbo) an EBC is not really worth it.

This type of turbo xs vavle have a ball and spring design so that the wastegate does not open until the set boost level is seen (no wastegate creep) this results in faster spool up. I have the brass part of the controler open by half a turn and then fine tune the boost with the top blue part.

Its interesting that yours spikes and mine does not.

      You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.

      By cosline · Posted

      Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik

      Spotted on the street....

      By Rezz · Posted

      Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
