So i'm lookin for more power(aren't we all), my mods are in my sig. I am running a powerdyne(I know! I'm on a budget here). I am running the stock block and am wanting a little more power without the BOOM that is bound to happen eventially. I was thinking maybe methanol or something like that. My intake temps are around 135-140 with an abient temp of 80. So I'm open for ideas here. I haven't ran it yet but i want to get in the 11's. Thanks in advance.

We'll need a little more info first, is the powerdyne maxed out allready at this point? What are you usung to tune the fuel enrichment and ignition timing now? Running meth wont really get you any more power unless you use the cooling effects of the meth to run more boost or more timing.

get the alky injection and a different cam.. what tune do you have?

Dennis93TA

It's dyno tuned. I don't know much about it. I could probably copy it with my burner and look at it.I think it's as good as it gets until i raise the octane level or more boost(don't think the bottom end will like that)

bmwmcars

did you add a 2bar or 3bar map sensor and tune for that?

Dennis93TA

Still have the factory map.
This is a speed density tune also.

Are you wanting to increase boost with the meth injection, or just looking for more power with your current pullies ( more timing etc)?

Dennis93TA

either way really, just don't want to compromise the stock block. I'd feel more comforatable leaving the boost alone and adding more timing. I geuss i've probably run out of power options without a rebuild though.

Kraest

Change your cam to something more boost-friendly.

breakmyfootoff

How much boost are you seeing now? What timing are you running? I dont think I would go above 26 to 28 degrees of advance on a blown application, are you using a BTM for timing retard?

Raising the octane level will possibly reduce power on it's own, unless you already have a detonation issue that it would correct....otherwise you'd need to add boost and only add octane if necessary to keep it out of the bang zone. Be careful if you decide to do something like that. Raised octane will actually lean out your A/F ratio (due to slower burning fuel I guess) so you may need to add some fuel to compensate.

You still haven't said how much boost you're currently pushing. If you need more boost you have some limited options with the PD, limited, but they are there. If you're already at 7# or so I'd say forget increasing the boost.

Dennis93TA

I think i'm just gonna leave it alone. i am running 7lbs and that block won't take anymore probably. I'm gona go forged eventually then i'll up the boost.

canbaufo

Yup, I'd probably wait. Even though the cam isn't ideal the power gain from a cam swap wouldn't be worth the trouble with no more boost than that, so I'd wait to do it until the forged rotating assembly comes about. Then you'd be better off to switch to a higher boost blower, just a buy a used one.

Dennis93TA

That's what i'm thinking. I was just wondering if i could have picked up some more ponies with a bolt on. I like the cam because it sounds ooh so good, and the amount of boost i'm running i didn't think it even mattered anyway. When it blows, i'll put in a blower cam and run about 16lbs on a ATI or Vortech with an aftercooler.

canbaufo

Excellent choice, you may not really want that much boost unless you just want crazy power (may need more injector, replace gaskets more often, potential detonation a bigger concern, etc). I researched intercooled setups awhile back and got a lot of feedback as well. In the end I was most impressed with the Aftercooler setup and decided the optimum blower for my setup would be a V2 (I'll take a good deal on a V1 though). The aftercooler setup needs work to really be efficient though (bigger tank especially, arrange the flow differently from stupid instructions of course, and a better pump). Water is a better heat exchanger than air/air setups and the ability to ice it is nice too.

If not for lack of $$$ I would have already made the switch
