the 50t/.48ar is an awesome pump gas car. ive yet to really see anything that can hang w/ it here locally psi for psi...race or pump.
Mke, I take it your liken that .48 50T I am going to go over some interesting changes with Ben at AGP when I reorder. None of the changes will negate the current performance but might help it put out slightly more. I actually couldnt get it to surge even though some people say it surges. I would matt it at 2000 rpm and it would just go until the boost hit. didnt cause any problems.
Okay well went to the dyno 2 weeks ago. Here are some results the first graph is 20 psi and 24 psi, and the second graph is 26 psi and then tried to crank it up to 28 psi but my damn coupler from my charge pipe to the intercooler blew off. All runs were done on race gas with absolutely no knock the 26 psi run was at 18* of timing at redline. Also the car has no return or regulated rail all done at 58 psi fuel pressure. I am pretty happy with the numbers besides the 20 psi pull. Made 410 hp at 26 psi I was very happy with that. I have a AFC Neo but I was not using it to tune with at all, as you can tell by how rich I got.
Power Mods are as follows:
AGP DBB 50 trim
MPX 3'' dual exhaust (not cat or res)
AGP SCT flash
E.D. hardpipes
MPx FMIC
Lorenzo 62mm TB
Ported and Polish Intake manifold, matched to the throttle body
DCR full oil system with top end modifier
D.W. 750 cc injectors
Walbro 255 hp pump
Hallman MBC
I think that is it if I think of more I will list them but I am pretty sure that is all of them. Anyways here are the sheets.
Once you dial in the Neo to get you in the mid 11s on AFRs you will be making 400 at 20 psi and probably 440 at 24psi. You will spool sooner too. every turbo I have ever put on this car spools crappy below 11.0 AFRs.
i don't think with out a return line i will be at 400 at 20 psi, maybe 360 or so but not 400. i mean if i am great but the car runs amazing right now. i am going to be talking with kevin at agp to get my car dialed in at 20 psi. btw the car had not reached operating temperature on the first run, i didn't relieze it at the time of the pull, if that makes any difference.

I am seeing more and more amazing things as time goes on. Theres a car owned by one of the mods over here in NE that ran 128mph without a return line. I would say thats over 450hp right there. It looks like your car has plenty of fuel. I would just read your wideband and pull it where needed and you will be golden

i will give it a shot i am not really worried about dyno numbers, the only reason i went and got the car dynoed was because the indiana srt club had it's dyno day. I am going to get everything fine tuned and hope to see some 12's on street tires at the track. I had my goal set for 400 hp on the dyno so 12's shouldn't be to far off.
if those afrs are correct on the dyno sheet, youre in the 10s right after spool up till about 5500, lean that section out and boom like addicted said, 400 at 20psi

oh i plan on getting it taken care of. my biggest question is what effects on my afr's would it have by my car not being all the way up to operating temperature? i know it would be in closed loop but would it have the much of an effect on it. because kevin at agp was saying that at 20 psi i should be mid 300's no problem.
18* of timing at redline seems somewhat low, what was your tming throughout the powerband? you can prolly add some more timng to your table thatll help get you some more power
