Thursday October 20th, i will be dynoing my car and getting 680cc injectors installed. WOOT. Ill have to post my dyno chart when i get done, and video LOL.

Matt D. · 10-12-2005

You upgraded your injectors because...? Why dyno your car, do you have some way to tune it now?

Jakey · 10-12-2005

Does your car have a mod list besides a T28 & boost controller Tom?

tpunx99GSX · 10-12-2005

Mods:
T-28
Boost Controller
SAFC 2 (in dire need of a good tune
Exhaust
Intake
HKS SSQV
680 cc Injectors *getting installed right before getting on the dyno
Rewired Fuel pump

injectors are to large for the combo, result: car will run like shit and make crap for power.
Good luck

tpunx99GSX · 10-12-2005

we shall see. Eventually i will be going with a 50 trim and my FMIC will go on. I would think the 680s should be fine for the setup, and being able to back off the fuel using the safc they should be able to tune it fine. We shall see, and if it runs like crap then we will have to go down to some 550s or something along those lines.
BTW Josh you never got back to me about the price list i sent you.

TheBlizzard · 10-12-2005

Yeah Tom 680s are way too big for the mods you have, the AFC might not have enough room to compensate for them. You might be able to get a half way decent WOT tune, but its the idle that you are going to have a lot of trouble with. Just get some 550s, that will be more than enough injector for that T28.

-30 should work for those injectors on the safc. What does averyone think he will put down. I am guessing right around 200whp.

Jakey · 10-12-2005

SAE corrected 200whp

I'm thinking 190whp, if the body kit is still adding a few ponies.

tpunx99GSX · 10-12-2005

Mind you i will be running 16-20psi

tpunx99GSX · 10-12-2005

Im hoping for ~250 after the tune.

I stand corrected, 189 whp.

LOL, no stop saying that or you will jinx me. "Ive got hiiiigh hopes, we got hiiiiigh hopes, we got high apple pie in the Skyyyy hopes"

The stock 450s might have been good enough.

Around -30% will work fine for the low throttle and idle, but in the high throttle settings you usually have to go a lot farther negative. If it doesn't flow much air, though then you might be fine. On a bigger turbo with 660-680s on a 2G you often enough up being in the -42% to -50% range on the AFC. The main drawback to going so far negative on the AFC is that it puts the ECU into the wrong airflow maps and often trys to run too much timing, which results in knock. 2Gs don't run nearly as much timing as a 1G, so that might help a little, and without a DSMLink to see if it's knocking or not you won't know how much it is retarding timing, so you can instead just pretend it's fine.

It should run fine though, I hope you have a FMIC for that much boost.

why not just get an eprom ecu and socket and chip it?

Thanks for the info. So your saying if i got the 680s it would in effect be fine, just a lot of negatives. But if i got the 550s that would put me less negative correct?
I have a FMIC, its just not installed or piped up on the car yet, would that work. LOL Ive run 16-20 on a daily for the past 8 months without hitting any fuel cut, but we will see i guess. LOL
The shop im going to said that Cams might help out as well, but i dunno...

Put the intercooler on it before the dyno, why wait?

Jakey · 10-12-2005

What shop is your car going to?

niterydr · 10-12-2005

argg...
We are telling you tom, that with the 680's on a t-slightly to small, the car is going to run like ASS and make shit for power. Either resize your injectors, wait until the larger turbo, and find something else to tune with. See what they can do with your factory injectors and the fmic, keep the 680's out of there.
