Not going to get it done this winter since I am just getting started with parts accumulation. I am putting together a 550CI + big block TT combo for my 2003 cobra. Planning to back it with a th400.
I am going to try and keep my inexpensive this winter, last winter i spent way to much money on this money pit. This year i want to get the tune/o2 sensor issue figured out hopefully it is just a wiring harness. Crank up the boost to 25-26 psi on E85 hoping for 900+ rwhp but would be happy in the 800s. If a new wiring harness doesnt fix my o2 issues and cant figure anything else out i will probably switch over to a stand alone engine management unit like a holley or bs3. I would also love to put an auto in it over winter but i dont think the funds will be available this year.
What seems to be the problem and what's your current combo, turbos/injectors/fuel pumps? Shouldn't be hard to get over 900 as mine made 932 @ 25 psi with a single. Had more in it but maxed out my injectors.

ever since i went to have the car retuned for the first time when it had a kb on it they have not been able to tune the car properly, for some reason both tuner i have taken it to have had issues with o2 sensors were they had to turn off all 4 sensors. we though maybe it was from when i changed the clutch that i put the harnesses on the wrong side but those got switched from side to side with no change. Now we are down to a bad wiring harness so that is getting switched out right now to see if that helps anything.
current set up is 2-garrett 60s/ acceleronics 95 lbs/hr injectors with a versafueler / 3-300 lph walbros w/ a glenns performance sleeper tank. my biggest restriction will be my injectors but once i get everything figured out on a pump gas tune i am going to be taking the car down to Bob Kurgan to have him do a e85/98 tune on it and i see it getting 900+ just depending on what the injectors allow
we recently made 1062rwhp on e70 in des moines, IA on 25psi and stock ecu with 160lbs inj... and 2 months ago i made 945rwhp on a single 76mm with 80lbs injectors, stock ecu, and e85..

Wow those are some awesome numbers Bob I really wish my car would have been done in time for when you were up in Indy a couple weeks ago. Do you see yourself coming back to the Midwest any time this year?
