E85 Fp black, stock block
Mikey has a point, the 03 engine is a little weaker. Your are referring to a 35r compared to a black that is spooling around 400 to 500 rpms faster. Although, I do think this dyno is reading a little higher than a dynojet. To the Op, I think you have a fun ride and nice power curve! So I hope you enjoy it.
Where did you get your info? Don't talk anymore.
yea it feel damn good and ive turned it down a notch for everyday use , that and i really dont rod the **** out of my car so im not to worried about my motor right now. Hopefully over winter i will be 2.3 anyway then i can see what that black really can do
Even if this dyno reads a little high I don't think 28-29 psi on the stock block is unsafe especially on a good e85 tune.
And I don't think 450tq is the automatic breaking point for the motor even on a DJ.
Good work by JM on the tune, looks like a fun ride timmay. Where in idaho do you live?

Just seemed like everyone got their **** in a bind when I say be careful with the tq on the stock motor.
I see a lot of people losing the stock motor becuase of tuners. Boost isn't the problem as much as the cyclinder pressure and tq numbers. I believe that all stock motor should never see more than 15* timing or more than 425tq if you expect for it to last. jmo

i fully agree on the tuning, tq numbers depend i think over reving would cause more stress personally
im not doubting what your saying, like i said above ive turned it down a touch so less to worry about
and btw my peak timing is about 16 deg

One thing that you need to account for is elevation, at higher elevations you can get away with a tad more timing. Timmay is at 5000 feet of elevation. At sea level obviously timing would be a bit lower.
Elevation plays another roll in cylinder pressures. So 2 degrees at peak boost/tq and 16 degrees peak RPM (7700rpm) is not going to hurt the motor, not on E85 and 5000 feet of elevation anyway.

Sick numbers. When does it fully spool? Also what turbo did you come from previously? I'm trying to decide if I should just sell my red since it's not installed and get a black lol.
Also on another note, what causes people to throw rods? Is it from the rod bolts breaking?

id have to check logs to see RPM it depends on where i go from, i want to say around 5-5500 im full boost, i came from a gay *** buschur 20g, made 400/400 on it last year on e85

Of course not man!
Nice, my sister lives in Challis and so we got thru Pocatello on our way up there. Next time I come thru we should meet up, I'd like to check out your car.
I wasn't saying you were wrong I just disagree to an extent. As far as the stock SB goes TQ isn't the ultimate factor. Its dangerously high spikes in cylinder pressures which comes from detonation. With a good tune things can be kept together pretty well. Each motor is different and yes there is a certain safe limit for TQ on the stock bottom end but I don't think its automatically 425TQ or 15* of timing.
Also 8's and 9's take different timing.

Every car is going to be different, some evo's can take some timing while others cannot. It's all about how the car is setup. Just gotta tune each car to what it likes, and tuning via MBT too.
