Alright guys so my car is fully bolted and needing a retune. I have a 2009 so my injector seals are not e85 friendly. I go to school down in the city where e85 is everywhere. Im thinking about getting the Opel Injectors before my retune and running some E this summer. Is that a bad idea or no? I think I should be okay but would like more input. My head is stock 100%. Also ZZP will be tuning my car on their dyno.

Also, what kinda numbers are you guys pushing on a 24-25 psi e85 tune ? Thanks

Get them

Cobe

Lol okay looks like im getting them. Hahaha no seriously tho why do you say that

cmiller8006

There bigger, lowers injector duty cycle. And gives you room to grow

Cobe

Okay then im going to get them. What kinda numbers do you think ill make ?

The injectors dont add any power. Expect 20~30hp max from switching to E

Damn, this little ni.gga still around? How's college? You doing good? You actually man up, mature or you still clubbing and being the high school honey glazed ass troll you were?

Cobe

I know the injectors wont at this point in time. They will once im built and I was wondering how much more I would make on E . Is 400wtq possible ?

Hahaha I never went anywhere and yeah I operate and set up CNC here at a family owned tool making shop 55 hours a week and go to specs howard for digital media arts . I might still troll a lil

Unless you plan on upgrading your intake cam with a larger hpfp lobe, and/or plan on going with a larger turbo with e47, I really don't see the need for the larger injectors. Also consider this. If you just slap on larger/higher flowing injectors into the system, you're now exploiting the primary weakness in the system to begin with. Which is the hpfp no longer keeping up with volume demands and rail pressure tanking even worse than it would to begin with now that the injectors flowing more, which now results in ever larger injector pulse widths that now starts trickling down to further issues and ultimately leaning out. If you plan on doing all of this, I say then go for it. Otherwise don't even bother.

I also have an 09 (clearly judging by my name.. lol) and I've been running an ethanol blend in one form or another for over 3 years no and never once have had an injector seal issue. Is it POSSIBLE that your engine came with the incorrect seals? Sure. You however won't know until you, A) pull the injectors to check, or B) run ethanol and find out when they fail. Granted the ladder isn't the best option BUT, point is, you likely won't need the larger injectors and if you do, plan on shelling out quite a few more bucks to back the weakest point in the high pressure system to begin with. The hpfp.

Wouldn't the injectors act like stock unless tuned for anyway?

just save up for a zfr cobe

PrincessTurbo

what kind of gains with fuel lobe cam and these injectors would you expect on a fuel hungry stock turbo lhu?

25HP ? If I can run full e85 stock turbo again I would be thrilled.

I don't think you will make much more power but you will be able to make more torque. And the ease of not having to mix fuel each time you fill up

PrincessTurbo

Man I wonder if its even worth it then. Term said my rail pressure was dropping really badly on my new engine and I was wondering if maybe just a fuel lobe cam and some opel injectors would bring it back to life again. I mean it pulls fine but it isnt the " same " he said the new setup flows more air so needs more fuel and thats what I am basing this all off of. currently running an E blend ratio .

they are cheap enough and worth it to get more fuel imho... i completely maxed the stock fuel system out at 442whp with absolutely nothing left for fueling on the top end.

PrincessTurbo

If I got a 20 hp gain on new lobe and injectors retuned I would be happy . Is that hopeful ?

Omiotek

iTrader: (2)

i dont see why not..... theres a lot of variations but i think you can get there with an aggressive tune. but more or less the thing is to just ensure not running out of fuel until you get to the bigger numbers

PrincessTurbo

Well I just ordered GM stage 1 sensors, fuel cam , new trans , clutch, opel injectors.


I would like some peoples opinions of tuners as of lately I just emailed terminator and he sold his HPT cable

So who is reasonable and trustworthy to upload a GMS1 tune copy the tables over and do a remap etc?


Sucks term used to hook me up.

Ryan I was making 359whp running e85 (@26psi) and stock turbo and Term said I was "pretty close" to maxing out the fuel system at that time.
At our altitude we can get away with a little less fuel of course, I'm sure that setup at sea level would have had issues...

Yes it sucks that he no longer tunes, he was the only guy I trusted with my car. If you find someone else let me know

PrincessTurbo

Yeah Adrian, I was like hey bro when can you tune me again..

When he told me he sold the cable my heart sank. We got love for ya term

Not a hard on just tuner love.

Terminator said I could benefit from some fuel cams my new block/head flows that well. Might as well get fueling checked out and nailed out before carrying on. Sending this core to be built in 2 weeks.

Cobe

Okay I understand but wouldn't zzp just tune the injectors so they arent causing those problems??

09CobaltSS1

Sure, but I still don't see the point in it. I made 350whp stock turbo with e47 on completely stock fuel system with zero issues. There is absolutely no hp gain to be had with going to these injectors on the stock turbo plain and simple. Is there a benefit to having them? Sure, if you're running straight e85 and/or upgrading the turbo. Even then, you would still need the supporting mods to supply the higher demands of the fuel and injector size. Just my .02

You cant go wrong with 09CobaltSS1. Really knows his stuff. Kind of an ass tho Seriously though, I had an issue that required logging and tuning and more logging and tuning, turned out to be a split hose on the boost canister in the end, he never quit till I was spot on. If you are looking for a GMS1 style setup, I think he could hook you up......

PrincessTurbo

So far James is the only one coming up.... Anyone else ?
