Default HP thoughts, 3071, WI, etc

So folks, I already have built up the bottom end of my 94 with ETD rods and Wiseco 9.1-1's. Walbro fuel pump, FM fuel rail, wideband, etc. It's currently a FMII with 2560. I currently have on order a 3071R, 750's, and water/meth injection. Any ball park ideas of where my HP might end up? Running a full Link ECU so max boost is about 18psi.

The head is stock?
3" exhaust?
Stock coilpacks?

I think you're looking at the 320'ish whp range at 18psi if the exhaust is big enough. No telling what your limiting factor might be... spark blowout, fuel delivery, cooling... the WI will help with your timing curve tremendously though.

What kind of power is the current setup making.

Head is stock with a mild port/polish
2.5 exhaust but it's straight pipe and has the new FM cast turbo outlet.
Stock coils at the moment but waiting for the WeaponX COPS to be ready.
I did install a Walbro 190 so hoping this with the 750's should be plenty.
Cooling so far so good with a Mishimoto installed. Still with stock Oil cooler but will upgrade if necessary. I also have a oil temp gauge.

It's never been dyno tuned so the regular FMII is probably putting out about 240 or so.

I think you'll see over 375 with your current mods, ditch the Link and you'll be able to get over 450.

I don't see how you ******* drive these cars north of 350whp on a real dyno. 300whp is pretty fun though, its just easy to screw up...fast.

I'm counting on it being a hand-full. Gotta scare the crap out yourself every once in a while, keeps you grounded. You're right thought, I'm thinking when the boost rolls in hard better be heading in the right direction, especially with 215-45-15 T1S's. They won't last long....

At 19 psi (measured at the ECU), my 2.0 litre produced 355 rwhp uncorrected at 5,000 feet (which answers Hustler's question). Personally, I find it quite tractable around town and devastatingly fast on the highway or a twisty two-lane road - and I'm only running 205-50R15 RS2s. Wheelspin does happen in lower gears, of course, but I generally run one gear higher to compensate and rarely need to take it out of fifth at highway speeds. Adding the Mazda Competition differential bushing has eliminated wheel hop, so any wheelspin is progressive and quite controllable.

I suspect you'll be making close to 330 uncorrected at the wheels at 17 psi (maybe slightly lower due to the limited resolution of the Link). In any case, it will be lots 'o fun!

I almost wrecked my car last week leaving the apartment when I rolled into boost in part throttle in 3rd while looking for the GPS...almost stuffed it into a wall.

Woke you up quick, didn't it?

Mine is a garage queen. Only drive it when it's sunny outside. Drive the Tahoe as a daily.

With a 3071R and WI, you should be able to touch the low-mid 300s at 18psi. I expect to be at 300 with a 2871R and 100 octane with around that much boost, and high 300s with 22-23psi.

I'm making ~300whp at 15psi with a gt2860rs on the begi s3 kit. He should be much higher...or I'm a tuning god and don't know it, which I serious doubt.
