well currently im at a different power level but my last dyno was 407hp/391trq. That was 25psi on 91 octane and really conservative timing (stupid 91!)

 

Nice numbers none the less.

What turbo are you running again, and what's different about the setup now (boost, fueling, hardware, ect ect)?

 

He was tuned on ethanol and a littler more boost and ramped in a little more. Not to aggressive on timing though.

 

nice think he has the 5557 pte journal...so i cant wait to see wut my 5857 does if he's putting down 407 on a conservative tune.....reading everyones post on upgrading and just enjoying the balts is making me sooooo sad!!!

 

yea i have the JB 5557. Now i am running e30 but i just got done rebuilding my engine. I also have a ported head and intake mani. But i think im going to drop some boost a little and do e47. Purely to save my tranny till i get some money saved up to build it lol

so i guess power level i may not be all that different but just different specs and mods

 

It all depends on dyno, heat, elevation and etc.

 

Nice numbers man! 30 whp from just an aggressive adjustment is pretty sick LOL, lets see the graph! I wonder if I'm anywhere near that to be honest. I want to be a little above 400whp for daily . I'm really considering switching to e85/47 or something.

BTW, I don't think I've seen above 25.5 PSI ether on my boost gauge with the EFR. Is this a coincidence?

 

Yeah, the boost gauge won't read past that. Mine stops at 25.5PSI and I'm running the 3 bars as well. I have to just go by the mechanical boost gauge.

 

damn RPD lol

 

I missed this post apparently. The graph is in the original post and yes I think the 25.5psi thing is purely a coincidence.. lol

I would love to see what this turbo can do on e47 with a 5th injector setup as well. He and I have been talking about setting up some more dyno time to really push the turbo just to see what can be done with it, but ONLY on the dyno.... nothing for the street. I'm shooting for a solid 450whp but we'll see what happens.

 

congrats OP very nice numbers and power band!

 

yea should be fun to see some high numbers on the dyno to see wat this thing can do...

Thanks bro deff feels good.. Im doing my exhaust tomorro and goin back to adjust the wastegate and see if we can squeeze a bit more out of the car..

 

Congrats on the #s man!!!! This is good **** and 09cobaltss1 props to you for tuning and having learned to tuned. Good **** guys.

As for the sensors, according to some logs that Term2 has done he has been able to determine that Stock sensors can read up to 2.7Bar, while upgraded sensors a little more than 3. I think it was a great idea going with a mechanical boost gauge than relying on the RPD, never know what its software limits are. On the Sky's our boost gauge is in the gauge cluster in the DIC. Mine always reads 24psi even though on the dyno with boost anaylizer I have seen 26psi. Currently I'm doing logs on a 27psi tune and I only see 23psi on the DIC.

 

Thanks dude!!! seems like the rpd is reading ok till 25.5 lol idk if it goea over that but in the logs as john said it was almost identical lol we will see tomorro i guess..

 

Hey thanks for the good words man. Truth be told, I've been tuning for a little while now. I just don't put myself out there maybe as well as I probably should. I'm always learning though!

 

so how does a 2900lb car @ 400whp feel anyways?...lol

 

Like a little freakin rocket.. lol

 

How do you guys put that power down? Traction is even bad sometimes on stock turbo with bolt ons and tune, jesus.

 

depending on baro pressure is where the map will have either more or less able kpas!

 

A good tuner can help with that lol... good tires are also a good idea

 

boost ramp that ****! Make it come in slow .. If you know what i mean (dirty thoughts here<<<<<<)

 

Exactly!! Saves ur motor tranny and tires lol

 

No problems really with traction. It's all the same, but then again I'm on NT05's

 

I would like to see 450whp as well! I'm hoping to hit that with e47, would I need a 5th injector for that?

PS I want to see the whole graph with the curve lol, not just the numbers. Post it up ixxghostxxi

 

I put re-11's on I can actually get a little traction in 2nd now! Haven't tested it out on kill yet though, and its been 90* every day too. Can't wait for fall and cooler temps.

Sorry for the off topic. Been awake going on. 48 hrs now.
