20G-LT + Dynoflash tune. I am VERY interested to see the results as that will probably be how I go eventually.

 

David B - if I got the 20G-LT and planned to run methanol with it, would I still need upgraded injectors or could I get away with stock injectors with the use of methanol.

 

Here´s a tidbit for you...On a basic mods Evo IX, equipped with an FP EvoGreen turbo, the stock injectors go static(100% D.C.) somewhere between 22- 24# of boost. That's on a pumpgas tune without alky.

 

Edit: Sorry, I mistakenly double tapped the "send" key.

 

I was wrestling with the same dilemma that you are, Soon2B..., about trying to run an FP Green which I ordered, on the stock injectors. My reasoning was that since Alky fuel tables in general, tend to be leaner than pump gas fuel tables, that maybe I could get away with running leaner AFR´s with the Evogreen and the stock injectors on an Alky map.

I even carried this line of reasoning one step further...I figured that even if I decided not to run alky, that maybe I could get away with running the EvoGreen in conjunction with the stock injectors at boost levels up to 27#, if I did it on race gas, since race gas allows for tuning leaner AFR´s than pump gas does.

Then I spoke to Robert at Forced Performance and he told me that during testing of the EvoGreen, on his Evo IX(w/stock cams, I think), the stock injectors go static at about 22#(or maybe he said 21#, I can´t remember) of boost.

I, myself decided WTF, I´d better play it safe. So I´m gonna throw in some 720's that I have sitting around the garage and have my ECU scaled. Better safe than sorry. That way whether or not I decide to do Alky...my motor won´t run the risk of leaning out and detonating to hell.

Or look at it this way...your 20G-LT compressor wil be moving a comparable amount of air to a Garrett 3071 or a 50-trim, and I wouldn´t trust the stock injectors on either one of those two turbos.

 

i was told to run 680cc injectors on stock ecu with the fpgreen

 

Race gas lets you run leaner, but the lower specific gravity of the fuel almost completely negates any benefit there. You end up with very nearly the same capacity.

On my car at 21 psi I move 42 lbs/min with the silencer in, and 45 lbs with it out. This would lead to 100% and 107% IDCs repectively on stock injectors, as an example.

680s are the smallest you should run, they just barely support this turbo.

^^^^
Good Info, thanx

 

Any numbers for this turbo on a IX...does the price justify the gains?

 

on pump gas i would say it is a waste of money. Thats a steep price and little gain for a 20g on a ix

 

$1,700 bucks for 20whp. And that was on the car with an AEM EMS and 94 octane, not 93 or 91. I guess it is up to the buyer if it is worth it.

 

I know that you cannot run the stock injectors on this turbo on pump gas. But methanol acts as a fuel, so Im wondering if I can run methanol injection with the FP Green on stock injectors.

 

any track times yet, like full weight...

 

I'd like to know the same thing

 

IMHO, You hit the nail on the head. That is a very expensive 20WHP.
