hey guys.. i just installed my fp green with a EvoIII exhaust manifold and HKS 40mm wastegate on the manifold. I was wondering how much boost would be max to run with meth injection on 93 octane and be resonably safe? my mods are in my profile.. and i will be tuning and logging with dsmlink.. thanks
 
Well you got the car and tuning and logging devices. Your really the only one who can answer that question. If you want to run max boost. Start at a reasonable number, and lean til you get knock, then richen it up a little so theres no knock. Just repeat those steps as you raise the boost until you run out of fuel.
 
20 - 21 pounds should be fine with 660 injectors a large turbo and some management ( which you have all of them ) personally i only run 18-19 on the street just to stay on the side of safety as far as head gaskets, detonation and hoping IC pipes don't pop off... i blew the same IC pipe off twice on my way home from tuning a WRX and an S2000 today over in iowa.. I even have T-bolt clamps on it, but it's a new routing and i didn't have it tight enough i guess
 
I wish i could help you a lil more but, my friend runs a FP green w/ maf-t setup and i know on pump gas right now he's running 24lbs on 93 octane, we are in the same boat as you right now until he can get it dynod and tuned too see how far he can push it.


I would say go and let someone professionally tune it and go from there.
 
yea, i forgot you said meth injection.. then you could run a little more ( 2-3 more lbs) but just watch teh logger for knock and either back some timing out or ad some fuel to keep it minimal

You do realize that Methanol is another fuel and allows you to run more timing, more boost and a leaner AFR? So why would you add fuel or pull timing? Please dont spit out nonsense..

yes, i know what it is... but to add boost and not monitor timing and kncok would be your so called "non sense"

adding boost just because you think or have heard it's safe is what keeps mahchine shops and performance shops in business.... to make any mod without monitoring the effects of it is just plain stupid.... as for running leaner on meth...HAHHA.. go ahead and lean'er out and add more timing..i'm sure some one needs to sell a block, pistons, head etc.... making any change (especially more boost and more timing ) without checking it afterwards for adverse effects is non sense.....


sure i could say "add methonal and crank the boost" but when his motor blows and he comes to me asking why it happened, unless i told him to monitor what is going on, would pretty much make it my fault ( or more his own for taking a stragners advice ) but either way... when you make changes...verify that your motor is still running safe.

what if the alky/meth injection isn't jetted right and the motor pops? does that mean it's some defect in another part because "methonal allows you to run lean, add timing and more boost"?????? i think not... i've been dyno tuning for over 15 years, and if you want to add timing , boost and run lean because you've heard that it's "ok" to do becasue you run alky/meth, then go ahead, but i watch what i do and none of the motors i've tuned have blown up as a result of my tune ( i'm proud to say) and it's becasue i'm carefull about what i do. i don't just go on what other people say, i test the results and SLOWLY increase timing and boost and only lean out hte A/F's by watching ALL the other parameters... do what you want, but me telling some one to be carefull IS NOT non-sense, it's COMMON sense


EDIT: and by the way.. i am the tuner and track support on an alchy injected 64 chevy that runs 7.72'a in the 1/4 mile and it's never ahd any problems with the tuning or popping a motor, so i THINK i know what i'm talking about.. i may not know everything about a DSM and it's parts, but i DO know motors and forced induction theory good enough to be confident in what i'm posting


EDIT #2: you have a completely stock car... so tell me where your experience comes from? internet babble, or do you have some proof to back up what your saying i'm wrong or peaking "non-sense" about????...sorry if i'm coming off as a D!ck, but when people say that i'm spitting non-snense i tend to take offense as i speak from experience nad my own tuning methods which have proved reliable, not just from what i've read or heard
if anyone thnks i'm wrong ...pleaqse chime in and let me know.. i'm alwasy more willing to learn than to be bull headed about what i think is right

Where should I start? Maybe you missed the part in his post where he said he has dsmlink and that's what he is using to tune with.. Last I checked (last week), dsmlink was able to monitor knock, timing, and AFR..

Monitoring the effects of what you're doing is called common sense.. I don't think I have to tell someone to use that everytime they modify their car, it's usually implied.. If they lack in that department, then they should step FAR far away from any vehicle..

If the kit isn't jetted correctly then it's installer error, in which ill effects will happen when it's not correctly installed and setup..

I never said "don't be careful" either, I basically said adding fuel on top of fuel and retarding the timing is not a way to get power from a motor/make it faster.. IMO, I would leave his 'tune' where it's at once he installs the meth and tune off of that..

I'm glad you're the tuner and track support of a 7 sec car.. That makes all the difference in the world to this thread..

When/why did MY car situation come into this? Does it matter that my car is stock? Does my car being stock represent that I'm a noob to modifying cars? Do you know my life story? If so, would you care to share it with everyone? This has no relevance on this thread.

The non sense part was about telling him to add fuel on top of adding fuel and retard timing when he installed his meth (which is a type of fuel as I'm sure you know).. That would make his car run AWFULLY rich, possibly enough to where fuel is dripping out of his exhaust (depending on what his current AFR is), and it would most likely run worse than it did.. Quite possibly fouling injectors within a few minutes time of idling..

I don't tune cars for a living, but I do have enough common sense that tells me fuel + fuel - timing (does not) = power..

then we shouldn't have a problem.. all you said to me was that methanol is another fuel that allows some one to go leaner, more boost and more timing... my only point was to be carefull and add stuff slowly and monitor it... if you're agreeing with that, then there's no point in us even bickering about it.basicly i took what you said as me not having any clue what i was talking about. sorry

Good rebuttal, well done. ROFL I'm glad you guys could work things out, now lets answer his question without all the extra "stuff" thrown in.
 
Well you got the baddest things to tune your car with. Seems like a nice setup, tune the piss out of it and let us know, cause thats the only way to find out....
 
wow.

I have almost the same stuff as you....

Turbo, fuel, tranny, clutch, .

You have Link.. which I believe, you need more fuel to run link vs. an e-prom ecu...

I run 20 psi on pump... With no link, and no meth inj.

I'd say 22-24 is a good place to start.

I'm runnin 40lbs base fuel pressure. I see 80% inj dc.

Great turbo though.... I'm trappin 118mph...

What do you mean you need more fuel to run link vs. an e-prom ecu?

Anyway, I have the Green turbo and it is amazing. For a journal bearing turbo, the spool is absolutely incredible. Im running 20 psi right now max. I have 660's and running DSMlink with AEM wideband(best mod out there). I don't have meth injection tho and I don't have have a cometic headgasket or arp studs. Maybe someday, but you should be able to run 22-24 psi safely. But like everyone before said just tune for knock if you don't have a wideband.
 
I'm putting together my 97 gsx now (hope to start it this weekend) with very similar setup and i was hoping to run 25-26 lbs on the street and going to be dynoing in the next two or three weeks. Let us know how you make out.
 
Ever go to the Dyno? Looking at the GREEN for 950 shipped..I have 650CC DSM chip stg3 and will tune with link when the turbo goes in.
 
I ran 27psi on my fp green with nothing more then 93 octane on 650's.

Don't try this at home kids.
 
A friend is currently running 27-28 PSI on a 2.0 with a FP green, flowing 49-50 lbs/min according to DSM Link. 93 octane with water/meth injection. Currently in process of switchto ing E85 so he doesn't have to bother with the water/meth set up.
 
I would start safe and run from there, I have seen cars with very similar set-ups run totally different. back off the timing, make sure your running rich and slowly crank the boost. I ushually start with a slow set-up, meaning a lot of timing retard, lots of fuel and I start to crank the boost and do some data logs. once you start detonating or running lean you can start to determin how much boost you will be able to run. As for the alchol injection, I have had the best luck tuning the car to get a base tune and then I start adding the alchy mix and see how the car reacts.

As always, error on the safe side and have a friend help you tune so he can watch the laptop while you do third gear pulls.....on the racetrack of course......
