Granted the hp is up there, but the tq isnt...arent people getting like 340+ wtq on stock turbos? If Im wrong straighten me out please, Im just wondering. Do you still have more tuning to do?
WAYYYYYYYY more tuning.... im sure he will see 400lb or whp when fueling issue is figured out

Yep way too rich. Or the sniffer on the dyno is not accurate. That could be a big reason it is not making as much power as it should. Even at 20 psi breathing through the stock components it should be making way more torque than it did. HP up top above 5500 would definately suffer some because of stock parts though. Torque should be closer to 370-380.

Which GT2871R is this? What's the inducer side of the compressor wheel? 51.2mm, 49.2mm, or 53.1?

What's the A/R housing?

Im going to play devil's advocate here a min... lets take a look at that a little closer. I run a 12.8 AFR and feel (even with DI) that that is too lean. An AFR into the 11's and still making 345whp is pretty good. Not to mention SAFE. I have built several turbo cars now, one being a 700hp 13b RE Cosmo powered FC3S S5. He runs 1260cc primary/ 1680cc secondary injectors (and a 255 Walbro in tank) with a street/side ported motor and a GT45 60 trim turbo. With our tune w/ Wolf 3D he makes near 700hp at only 13psi running an AFR of 10.8. But he can beat that car like Vince the Sham Wow guys hookers and see EGTs into the 1300's n not worry a bit about grenading that motor. With the right conditions, upgraded IC/IC piping (keep in mind its only 2" all the way thru, when in reality it should be 2 1/4" hot side, 2 1/2" cold side) and an intercooler thats rated for at least 600hp... with the additional airflow provided from the GT2871R running at around 20 psi, you have to figure thats somewhere in the 140% more cfm than the K04 running 23 psi... that stock equipment is going to run out of room. And quick.

but since I regressed a little too far... Maybe you could up your AFR to over 12 but if you can make good power and run a bit rich, I would go that route and eliminate the worry of burning holes in your pistons

[QUOTE=SportredSS;3931430]You obviously dont read the whole post he has plus the mods he has........ He needs IC, Charge pipes, CAI and two or so more lbs of boost ... That should be worth 28-34 more whp...

Some guys are getting 330-335whp on stock turbo with no upgrade turbine wheel or anything else.....

Plus, the DI engine likes the heat, it creates a better, more complete fuel burn in DI cars....

Lastly do yourself a favor as many of the kids on this site do not understand... anytime you add more than 70 or more whp to ANY car, you need to increase the size of your fuel pump otherwise you'll have starvation. R\R the fuel pump before you upgrade the DI system.... >> ( which we are all waiting on HPT to free up the Fuel system under the hood)........._


Yes, he might be able to make similar pwr with the stock turbo at 28+ psi and at this rate the turbo will not last at all....[/QUOTE]



PLEASE PLEASE PLEASE STOP POSTING>..no you dont need a new fuel pump when you add 70 whp or more to any car... look at this site there are VERY few people that are running different fuel pumps and there are alot of people running 70+ whp over stock..

and no obviously look at some other numbers on the site .. just cuz your tune is shitty and you didn't get 300 whp out with just a tune ... doesn't mean that you need to spin the turbo to rediculous places out of it's efficiency range to get power.. there's someone on here that made 316 whp from just a tune .... at 22 psi or so if i remember... hell add some supporting mods albeit that this car needs .. and you'll have similar numbers Terminator2 on here has the same whp and trq on stock turbo...

and i love how you contradict yourself too .. you way people are getting 330 or so whp on stock turbo.. but then say it'll take 28 psi to make 345 whp on stock turbo LAWLZ..

finally... ZZP with their turbo upgrade has ran everything on full stock.. cept the turbo pgrade and made better numbers yes it's a different turbo i know ..

The 2871R they use has am .86 A/R exhaust housing which will cause the car to spool a lot slower. As for the air/fuel ratios, it looks to me like he is a little lean up top which may be killing power. Not to mention the fact it is a canned tune from a car on the east coast that was placed on a car in a very different climate. The potential is there when he gets his new sensors and dials in the tune a bit.

Personally I wish Synapse would have used the 2871R with the .63 A/R exhaust housing as it would have been a better choice in my opinion.

Im pushing around 330whp right now and only at 23psi so what the **** you talkin about 28spi?!?!??!

No tuner in their right mind would set a stock turbo to 28psi plus the 2 bar maf sensores wouldnt allow it and if they did that turbo would be gone in a matter of days

this looks like a big waste of money.

and you getting blow by and then taking your car back to stock for warranty is just wrong. Man up and fix your car.
