Hi, can i put a nitrous kit on my 97 850 GLT wagon? If so what hp shot?

[flyfishing3]

[T5power]

go for the 100hp wet shot. when you install it let us know how it goes

Ive run a 100hp wet shot a few times, but on the lower compression t5 engine. I don't know how the higher compression GLT and the smaller turbo will react however, it most likely won't be good.

To the OP: This is not a good place to ask about about nitrous, as only a handful of members have run it on their Volvos. Most here do not understand or are afraid of it. Nitrous application is basically the same on any port fuel injected engine. Do some external research on the fundamentals, and then, if you have any specific questions, such as "where do I mount the WOT switch", ask those here.

But to answer your questions:

Yes you can run nitrous on your car and you should always start with a 35hp shot and move up from there. 50 shot should be ideal. Anything more and you will need a progressive system because of the nasty boost spikes associated with small turbos.

TorqueSteer speaks the truth, most members will dismiss any questions about nitrous but as long as your smart about it I don't think its any more dangerous than a MBC.

Yup, the key is being smart about it. Unfortunately, the smart nitrous setups cost almost as much as a turbo upgrade and custom tuning. After pricing out af gauges, progressive controllers, rpm window switches, ignition timing adjustments, bottle warmers, bottle openers etc..the cheap and easy thrill of nitrous is suddenly competing in price with other upgrades.

Yeah im in the same boat as you.

But if I may share some of my "wisdom." with the OP. If you are trying to put nitrous in a daily driver, its just not worth it. Yes I took the time to invest a lot of time and money in a very safe and reliable nitrous system, but in the end, I decided to sell the kit and go with a traditional turbo upgrade (no MBC lol) and custom tuning capabilities. Nitrous is fun and addictive, and while I don't regret it, I'm much happier now with the extra power coming from a turbocharger rather than nitrous.

Go for the 100 wetshot-- wtf????

That's ffff'd up!

For what reason?

[Gizmo]

I'd assume the typical reasons... MBCs are crude, can spike, don't have the associated fuel-map improvements that tune-related boost-increases do, and MBCs don't prevent high boost in the relatively-low RPM bands.


That said, I like mine. Just have to be conservative with it.

basically, every fly boy that comes on here gets all hopped up for major POWAAH wants one.
doesn't understand the diff between a MBC and EBC.
the lemmings don't understand timing, fuel, afr, many do not have a boost gauge. etc etc.
never heard of stage 0 etc etc.
they have no understanding on what it actually does,

i believe in a good tune and what i does. the safety of the engine is the key and a BC doesn't care about the engine.

generally nobody installs them correctly and starts a thread asking why the have 5psi or 25psi.

good car componenants usually can't be fabbed at Home depot.

for the right people, yeah they are fine. they can help stabilize a tune etc, get a couple extra psi.

but its trick and thats all it is.

Do you have/ever had a mbc or ebc?
I have mine set at 14 psi, works great for the past few months..
And the statement about good car components from the depot, is a very pompous thing to say.
Just because something is cheaper does not mean it can't do the same job usually just as well.
And just because a company has a really glorified looking mbc does not mean that it will perform any differently from a $10 shipped ebay mbc.

Come on now.

Do you ever pause and think about what you've typed, even for a second, before clicking the "add reply" button?

[TorqueSteer]

MBCs work, there is no argument about that. But if you want a safer, smoother boost curve that is optimal to your tune, electronic boost control is the undisputed way to go. All OEMs and almost all high power, reliable turbo setups use electronic boost control. When I switched to electronic boost control, it was a night and day difference; yeah I used MBCs for awhile to up my boost, but I knew it was a hack shortcut and I never actually defended them as being a great option. I welcome anyone on here to post that they have switched back to manual boost control after going electronic (and not because you couldn't figure out how to adjust it ).

Well, for starters, do you care about part-throttle boost control? An MBC certainly doesn't. I ran one for the better part of a year, and ended up taking it out and going back to stock boost because I hated how it loved making lots of boost at 1/2 throttle. Even at stock boost levels, the ECU was running it so lean I could hear the detonation on cold days

Yeah, you've got to be really careful about MBCs on cold days. And johnloves850's, I would dial that down to about 13psi... I ran an MBC at 13 for three years with no issues whatsoever. BUmped it up to 14psi, and I toasted an exhaust valve within 7 months. Granted that could have been cumulative, as I'm sure the anti-mbc crowd will point out, but upon tearing down the motor, everything but the two exhaust valves of one cylinder looked absolutely fine. the other four valves were even within spec where they could have been reused with a little lapping.

If I am missing something here, though, please point it out... I am fairly inexperienced in the way of turbocharged engines. I understand the part-throttle boost control concerns, but with my MBC by 15G wasn't making full boost until above 3500. Isn't that more of an issue of proper wastegate setup?

^^ edit, valves of the other four *cylinders* looked fine

does advance auto sell plywood?
if you tried explaining to MRS X in the plumbing isle, will she understand your trying to fool your car into going into full boost instantly?

listen, do what you want. all i'm saying is a MBC is not the quick/cheap solution to long term high performance and the majority of people who want them, have no idea what they are getting into.
