dry man. unless the wet is port injection like the pics above.
like stated before. an S2 it may work it being an NA. but when you hit boost and something goes slightly wrong.......boom.
well...from what ive read from super tuners.

there are numerous people running wet shot kits on volvo's under boost, fogger systems to be specific with no reported problems, these are "dry manifolds" as you describe, what about running additional injectors on a car ? i know under boost conditions its common practice especially with a piggy back type setup for people to just install the injector pre throttlebody and have it spray directly into the intake, hell volvo went as far in the 80's as making a cold start injector that did just that on their cars. is this theory that you preach or do you have something concrete to back it up ?

Best way: wet, port injected (as seen in the pics). Nitrous Express makes a plug and play way to do this.http://www.nitrousexpress.com/Catalog/2005/nxl.pdf
2nd: dry throttle body plate.
I'd advise against a wet throttle plate setup, but on the other hand You'd have to convert to a throttlebody injection to even do this.
Everyone here seems to be against spraying while you're in the boost. I think if the car is tuned, it would be better to spray while under pressure and here's why: Your charge air temp will be greatly reduced, meaning you will be able to run more timing and a leaner condition, which translates to more power. I think the intake temp drops alone will make it worth it. However, this also means you should be running a VERY good piggyback or a standalone computer, along with very good knock detection and the ability to retard the timing and add fuel in the event you run out of nitrous while deep in the boost. I think with a 50shot and moderate boost levels you will be safe with stock internals.
but remember what campeck says, when something goes slightly wrong. . . . . .. boom.
Good Luck.

sure volvo. I knwo it sounds dumb to say i read it in a book. but the book is written by a tuner who tuns engine management systems and has so much info in it. he has detailed description of lots of project cars hes done. and a certain crx comes to mind where the 3rd dyno run he did on a fogger system fried the valves.
im sure fogger systems will work great once some ppl have dicovered what works. but would you want to be the one who tried the "lower form" of nitroud first on YOUR car. if you dont know what works and arent willing to take the risks...dont do it. wouldnt you agree?
jeez. sorry for the spelling. and i dont mean any trouble volvo. some ppl seem to think i do. but i dont.

yes. those are cold start valves. they are to get the car running and thats about it.
they are not used for fueling each cylinder reliably and consistently. and shouldn't be because there are BETTER alternatives that are hardly not any more expensive nowadays.

no pioneers on porsche's side there... i was just using it as an example.
although they're only designed to be used at startup, its common practice for volvo tuners to do a simple hack that allows the use of the injector when needed.. such as running more boost.
