quick question on mod path!

[bd91talontsi]

ok so I've had my talon for a few months now and I'm ready to start upgrading farther! now that I've fixed all the bugs from the previous owner. My goal is to just get over 300 awhp
so here is what I have so far,
91 talon tsi awd
performance mods are as follows:
accel 8 mm plug wires
deleted emissions
hacked filter canister with open k&n
removed lower honeycomb
turbo xs FMIC (28x11x3)
2.5" intercooler piping
two stage boost (15psi/17psi)
2.5" downpipe
2.5" exhaust
straight through muffler(don't have a clue what kind)
test pipe
ngk bpr7es plugs
fidanza aluminum flywheel
fidanza street clutch
pocketloggers logger
auto meter boost and egt gauges


there is the list as of now, I was thinking of getting a 255lph fuel pump and a big 16g next

what kind of hp #'s should I be pushing now and what would I have with the fuel pump and 16g?

there isn't an awd dyno anywhere near here so I can't dyno my car

your best bet would be to tally up the numbers through the Modification path in the Tech/DIY...you can maybe estimate the numbers

A dyno is the only way to determine what kind of power you are, or will be, making. We don't guesstimate HP numbers here.

If you intend on getting a 255, consider an AFPR as well, to avoid overrunning the factory FPR.

your best bet is to get the 190lph walbro, its what i run and it is 100percent better than stock and you dont have to mess with your fuel rail by changing the FPR since it wont overrun it. just my 2 cents....

If you have no intention of ever going over 300whp then the 190 lph fuel pump is fine, if you plan on going over 300 then get a 255 and an AFPR.

You need something to do fuel control, a good old Apexi AFC works just fine if you spend the time to understand what your logger is telling you. While you are at it bigger injectors are also something you are going to need, don't go over 650's on the AFC without getting an eprom to correct for the larger injectors.


Turbo comes after fuel control, a B16g is a fine turbo but there are other turbo's out there.

If you do get the bigger pump (255) make sure the AFPR you purchase is a 1:1 rising rate regulator. The best route in my opinion and experience will be an Aeromotive.

I've seen way more than one walbro 190 overrun a stock FPR pretty good. You should get an adjustable fpr w/ any fuel pump upgrade. Which will be required for this level.

Your stock maf even w/ the lower honeycomb removed will definately be overrun at this level. I know from personal experience, you're looking at around 28 lbs/min max before the 1g maf starts skipping hertz counts and your ecu thinks airflwo has gone down. Then the ecu shortens injector pulse width. and BOOM!

Upgrade to a 2g maf or MAFT. or an evo maf. Dial in your fuel trims w/ you injector upgrade w/ the stock maf. Then look at maf calibration if you run other than a 2g maf when running dsmlink. W/ an safc2, I'd just get a good idle tune and then use a wideband to get everything in line.

Your 14b will be hard pressed to reach that number in stock fashion. Upgrade to a used 7 cm^2 turbine housing for relatively cheap and you should be able to reach that goal. You have enough intercooler to more than make up for the ineffciency of the compressor at this level.

You will however still be really pushing that turbo. Just take care of it. Cool down before shut off and running the stock air to air oil cooler will help w/ it's survival.
