OK now it's a contest, I am guessing 340rwhp and the winner gets an old truck lug nut.

The ol' Gt3076R wont run outta breath until 525hp. I wonder how many psi it will take to Jam 50 lbs/min thru there?
Iguess I should build another intercooler while I'm at it. Although I guess it would be cool (and funny) to see what the stocker can do. P1/P2 ought to be hilarious.
Like I said I really really like Liquid cores being a street/strip kinda feller. I have used the A/c system on a few different cars for the Heat exchanger and it's VERY effective.
I'll sweeten the pot, your old truck lugnut + an exploded saturn trans (FWD, dont get scared now lol)
Ok before I put my official WHP estimate down lets define the parameters.
What kind of exhaust are we talking?
Intake setup?
Lets also estimate for max power under 1 degree of KR on 93 pump.
So Stock intercooler eh? ( arg ) Dude seriously I wouldnt. I mean at first is fine, but if you wanted another 40 whp upgrade, new intercooler plus tuning will = nice gains.
You tell me what the exact setup will be, and I'll guess within 8 whp.
1st test will be
1)pumpgas
2)stock exhaust
3)stock intercooler
4) shooting for 18psi (and if the F'er dont gimme it I have a Eboost2)
only mods will be the GT3076R and accompanying BOV/Gate.
tuned by HPtuners on a Land-and-Sea dyno. For comparison's sake it's pretty similar to a mustang dyno or 12-15% lower then a dynojet.
Winner gets gargemel's old lugnut, a blownup saturn trans and oh hell why not a carbon/Kevlar engine cover in your choice of color.
Closest without going over wins! Bob Barker'd be proud!
Yep got limp mode with everythign Ive tried on this thing,Randy.
Some dataloggin,some reflash and 5 min later no more limp mode.
I have the factory sensor stuck in a 4" pipe. no limpmode. It's all relative.
What I havent been able to do is stuff double the lbs/min thru the motor with this little peeshooter. But it will give me some nice data and insight into what measures the PCM will take against it. Perhaps it may help the boys @hpt.
So lets put limpmode out of our head, if it gets really pissed at me over the HIgh psi I will reduce boost until it's happy. Im most interested to see if she tries to shut the Throttle down on me.
I have a feeling it wont though. It only reduces boost on me when I have deviations from CMD to actual A/F. It only reduces throttle angle at redline and if it goes over 22psi. I think if I can maintain A/F and keep it below 20 psi she's just gonna sing her little heart out for me.

I have no doubts about the turbo's ability, I just wonder how you will overcome the ECM NAZI, that sucker is mean and does not take well to being messed with. I know the stock turbo will spike to 300 rwhp, but almost instantly goes limp. I think if anything I maybe high with the 340, if HPT comes out with an update soon I will change my number.

Indeed,
well I do speak half-ass German,lol.
well I havent run into an obstacle yet with the Ecm that hasnt beenable to be programmed around. But it hasnt gone this far out of parameter either.It should prove interesting nonetheless.
my guess would be that the liners fail around 600hp. give or take. Sine Im chasing the power up the Rpm band the net cyl pressure goes down to make the same Hp @ a higher RPM. Just more frequent bangs.
It will be interesting to see if the piston crown or ringlang gives way before the Cyl wall does.
Well I know for a fact that the injection cycle still occurs during the intake stroke NOT the compression stroke during PE mode (as Per a Bosch whitepaper) so duty cycle is calculated as it is in any other car. That being said, Ive only logged a max of 29% duty cycle.
Mind you now, as RPM's increase the injection window narrows so Duty cycle goes up by default even @ the same PW.
The primary/secondary pump should be able to support 400whp. That is my opinion based on the datamining done thus far.
cyl wall will definately let loose first. open deck design = split block, lets just say i know first hand. the pistons looked fine other than where they got wedged in the bore when it split.
i'd like to think 400 hp would be possible with an intercooler, exh, tune and turbo upgrade but i dunno with the stock stuff
just like a f'n honda. Ive had them split top to bottom on my dyno. But that was detonation (Someone gave the Dizzy a turn,advancing the timing about 20deg) Open deck sux, too hard to keep the bores from walking unless you recess them into the Head deck.
My reasons for experimanting with the stock stuff is simple= curiosity. I have (4) 4bar pressure sensors hooked to my HPT module.
When I post my findings you'll see difinitivly the P1/P2 from the stock intercooler, P1/P2 across the turbo (turbine inlet pressure Vs outlet pressure) and post Cat.
