using 19psi now and then on 1a chip?

[Markus74]

Hi all.
Recently had a vacuum leak fixed. Was warned that due to where the leak was (t piece off plenum for boost gauge), gauge may have been reading less psi than I was actually producing. Well the thing is it both feels like its pulling harder now and the boost hits about 19psi now quick as a flash.
I am at 1a with all necessary bits plus tubular Mani. I know I'm supposed to go Max of 17psi on jez chip but what damage will I be likely to get keeping it at 19psi?.
I very rarely use WOT, only give it the beans now and then, not on the limiter drifting or prolonged driving like a tit, my car is my daily. Ta

19 psi is well past what that Turbo can push, you'll just be throwing out hot air.
It's also past the amount of fuel the stock injectors can manage too.

Expect fun things like detonation and holes in pistons for xmas.

Turn the boost down, especially now as it's winter and you'll be getting colder denser air in anyway.

Doh!but it feels sooo good. Just didn't think a 2lb difference would be too detrimental. I'll wind it down ta

dont run 19psi on that setup

If you want more power, it will be a lot cheaper to turn it down then invest in upgrade parts to take it to Stage 2+ than it will be to leave it as is and risk having to invest in an engine rebuild. Det doesn't take long to spanner an engine as it tends to break the ring lands and broken chunks of piston rubbing up against the barrel walls isn't how it is supposed to be.

Thanks mate. Will do. Maybe you can answer this too. Asked on Horsham thread but no reply yet. Can jez remap my 1a chip for s15 injectors but minus the z32 AFM?. Can't afford to stretch to 555s

I'm sure he could map it but I bet the cost of mapping would be more than you would save on injectors

[Jonny Wilkinson]

The simple answer is yes.

Whether it is a good idea or not is another question.

People usually go with the off-the-shelf chips with a specific map (i.e. Stage x) if they can't afford a custom-written map. The downside is you need to match the spec of the car to the map.

If you go with a custom map, you can fit what you want to your car and get a map written that matches your spec. The downside is that the map becomes useless as soon as you change the spec.

With an off-the-shelf chip, you can sell the chip on to someone else.

Thing is, tuning cars costs money...one way or the other. Either you invest in the right kit (which costs money) and you minimise the risk that its all going to go bang or you go tuning on the cheap (crank up the boost) and accept the very much increased risk that is is going to go bang and cost you money in terms of a car you can't sell or the cost of a rebuild.

You pays your money and takes your choice but either way you pays your money.

Ahh I see. Hmm, back to the drawing board then :/ cheers

[sideways14a]

He could map it but it wouldnt be worth it imho, basically another 10-15hp as your limited to the afm and turbo.

Thanks man. All 'good under the hood' again, back to 17psi now. Treated it to some shell nitro fuel as its dirt cheap at the mo and despite turning down boost, car still feels naughty enough.
I'll stick to 1a for now then as cash is defo short, was just an idea about injectors as had been looking back at past threads & they seem to go for pretty cheap. I'll prob end up leaving it as it is for a good while as chip, tubby, 555s and maf are unachievable for a while

Gotcha, ta. That's a lot of dosh for a relatively small hike in power

[Mark]

This is what happens when you run too much boost

Things get pretty expensive from here on in, so be warned

[Markus74]

Waaaaaahh. I've actually been back out and further knocked it down a tad more as it was spiking a bit. Its a job to accurately watch what boost its hitting while keeping an eye on the damp road at the same time. Think its 17psi now

[Markus74]

Luckily, I have fook all dosh left now after welding and getting some other stuff done lol

[Jonny Wilkinson]

lol. I bet that wasn't just occasionally hitting an extra 2 psi though. That's a serious meltdown

Still, I suppose it doesn't much matter how scrap your engine is if its scrap
