ok i have a question. im thinking about doing the dynoflash and a manual boost controller to get a little more power. but now im also thinking about just doing a boost controller and upping the boost to like 24psi, but i gotta know a couple of things first. i met a couple of evo guys who are boosting 24psi with no standalones, or flashes. first off can u boost 24psi safetly on a evo without a flash or standalone or should u have some kind of management? and if i get a dynoflash whats the most psi i should boost with it? can u boost around 24psi and than have a dynoflash or will i need a more serious management? cause if i dont need a flash or stand alone its alot cheaper but im not looking to cheap out. thanks.

 

no I would not go over 19 psi on pump gas with out a tune.

 

The simple answer would be no. When it gets colder outside you often spike so its a good idea to keep your boost between 19-20 psi.

If you are boosting 24 psi and your motor in still in one piece on pump gas with no EM your luck is going to run out and your motor will be gone or you just lie.

Running more than 24 psi is possible with race gas and or alky.

 

are these replies from personnal experiences or from reading forums?

19. To start easing over that, you need to start by having the right gear to monitor and log what's going on. AFR, AIT, EGT, Boost, Timing, Knock, etc. The rick starts to rise exponentially as you increase over 20 on the stock program..and you will need to start really tuning then.

 

my car ran like **** when I tried to run 20lbs. right before my flash... anybody who runs 24psi with no managment is asking for a blown motor.

 

The typical boost that is run with a Dynoflash is about 21psi. You'll be happy with a base mail flash and an mbc set at 20-21psi. If you haven't done it already the very least you should do is get a turbo-back exhaust and a K&N drop in filter...then send in your ecu to be flashed for those mods.
Don't go around running 24psi on pump gas.

 

also.... you are not really meant to run more then like 22psi max without headstuds.

 

hmm.....oops

I think you can run more than 22 psi without any fears with apropiate tuning, gas., and I think headstuds are really not needed until you make more than 400 whp but I am NOT 100% sure. (Can someone confirm this) After all head studs only cost about $95.

Has anybody with a TBE, cams, fuel pump, mbc blown an engine without headstuds?

 

You should get the headstuds, its cheap insurance....

 

I run my 04 RS at 24psi at the autocross on weekends with no problems. The car has a custom Dynoflash for Megan Racing downpipe,cat-delete pipe and cat-back exhaust, HKS intake, APS blow off valve and a Hallman pro RX boost controller. The trick is to run 110 race fuel and nothing less. I will be putting the car on the dyno tuesday to see what the power is. I have done this before and the only problem is that the ecu likes to spit that PO300 or PO304 code for random misfire or cylinder 4 misfire. Each time it did this I pulled the plugs and looked at them and saw no evidence of detonation and a nice clean brown color to the plug meaning a good burn.

 

When I went to an event I turned my boost down knowing that my car was going to be running in boost for extended periods of time. Also during the event I had more than enough power to tear up tires with. I was in 4th most of the session, downshifting to 3rd in some of the tighter turns and hitting well over 100 in the short straits.

 

Don't listen to those guys that you know. I don't know why you correlate running 24psi with a flash or tune, because they are not related. You can't just randomly turn up your boost to 24psi and expect to make safe power as if that overcomes the need for a tune. A tune is going to make more power no matter what boost you run. Then, you can also raise the boost for more ADDITIONAL power, but these factors need to be used hand-in-hand, and you shouldn't be near 24psi on an VIII on pump gas with or without a flash.

Get tuned, get the right mods, run 22psi, and have fun. There's nothing magical about 24psi, and I'm willing to bet those guys you know think they run 24psi, but really only run 21-22psi. Boost gauges are rarely accurate.

 

Very true. On my old WRX my boost gauge was always reading about 19 psi of boost when I had it turned up. When I actually had my car dyno tuned at the same setting the real psi turned out to be 16.8 or so.
